Technical Field
[0001] The present invention relates to a device and method for evaluating the traveler
travel condition.
Background Art
[0002] The carrying capacity required for elevators increases with the increasing number
of high-rise and large scale buildings. The carrying capacity can be maintained by
increasing the number of elevators, while causing a compression of the floor area.
For this reason, the elevator structure has become diverse, such as a multi-bank system
designed to operate elevators by classifying destinations into a plurality of groups
such as lower floors and higher floors, a sky-lobby system designed to change elevators
at middle floors by using shuttle elevators, and a combination of the sky-lobby system
and the multi-bank system. From the perspective of travelers using increasingly diverse
elevators, it is important that each traveler can smoothly move from the building
entrance until arriving at the destination.
[0003] Patent Literature 1 discloses a technique that simulates the flow of people horizontally
and vertically in a consistent manner within a building, by combining a floor travel
flow simulator that simulates the movement of people within the floor, an elevator
movement simulator that simulates the movement of elevators, and an elevator boarding
simulator that simulates the boarding of travelers onto elevators, and then displays
the flow of people within the floor as well as the elevator operation condition.

Summary of Invention
Technical Problem
[0005] However, the technique described in Patent Literature 1 does not take into account
the change in the elevator structure. The time when travelers move within the building
may be affected by the elevator structure and possibly vary depending on the elevator
structure. However, it is difficult to evaluate this point by the technique described
in Patent Literature 1.
Solution to Problem
[0006] To achieve the above object, a traveler travel condition output device according
to the present invention includes: a travel time calculation unit that obtains a first
travel time for each user from when the user enters the building to when the user
arrives at the elevator hall, a waiting time in the elevator hall from when the user
arrives at the elevator hall to when the user gets on an elevator, and a second travel
time taken for the user to move from getting on the elevator to arriving at the destination
floor, and collects the information of the first travel time, the waiting time, and
the second travel time to calculate the travel time statistical information of the
user from entering the building to arriving at the destination floor; and a display
unit for displaying the travel times. The travel time calculation unit calculates
travel time statistical information in a first elevator structure, as well as the
travel time statistical information in a second elevator structure. The display unit
displays the travel time statistical information in the first elevator structure,
together with the travel time statistical information in the second elevator structure.
Advantageous Effects of Invention
[0007] According to the present invention, it is possible to evaluate how the time when
travelers move within the building changes depending on the elevator structure.

[0012] The description of the configuration of the traveler travel condition output device
with reference to Figure 1 ends here.
<Description of data>
[0013] Next, characteristic data in this example will be described with reference to Figures
4, 5, 6, and 7.
[0014] Figure 4 shows an example of the elevator operation record data 111. A column 401
represents the time when an elevator-related state change occurs. A column 402 represents
the target car number only when a specific elevator car number is targeted. A column
403 represents the changed elevator state. A column 404 represents the vertical travel
direction of a target car number only when the target car number is placed in the
column 402. A column 405 represents the position (floor) of a target car number when
the target car number is placed in the column 402, or otherwise representing the position
(floor) at which an event of state change occurred. A column 406 represents the estimated
value of the number of travelers of a target car number only when the target car number
is placed in the column 402. It is assumed that the elevator operation record data
are recorded in ascending order of the time in the column 401.
[0015] A record 411 shows that a call button for going upwards is pressed in the elevator
hall on the first floor at time 8:49:04. A record 412 shows that the No. 1 car will
move upwards at 8:49:35 while opening the door on the first floor, and at this time,
the number of travelers is 0. A record 413 shows that the No. 1 car will move upwards
at time 8:49:45 while closing the door on the first floor, and at this time, the number
of travelers is 4.
[0016] Figure 5 shows intermediate data when the elevator waiting time and the number of
waiting travelers are calculated by the traveler elevator waiting time calculation
unit 102 from the elevator operation record data 111. A column 501 represents the
floor on which the elevator waiting time is calculated, a column 502 represents the
waiting time, a column 503 represents the elevator traveling direction, and a column
504 represents the number of waiting travelers. It is assumed that the waiting time
is the time from when the call button of the direction to move is pressed in the elevator
hall to when the elevator traveling in the same direction as the pressed button first
opens the door. This waiting time is the waiting time of the traveler who first arrives
at the elevator hall, which could be the maximum value of the waiting time. Here,
the average of the waiting time can be halved on the assumption that travelers arrive
at uniform intervals. Further, it is assumed that the number of waiting travelers
is the difference between the number of travelers at the time when the elevator opens
the door and the number of travelers at the time when the elevator closes the door.
[0017] Figure 5 outputs the waiting time and the number of waiting travelers as intermediate
data used in calculating the traveler elevator waiting time, for each call of elevator
and each arrival and departure of the elevator corresponding to the call, in the traveler
elevator waiting time calculation unit 102.
[0018] The calculation method of each record in Figure 5 will be described with reference
to Figure 4. In a record 511, a waiting time of 31 seconds is calculated, based on
the elevator operation record data 111 in Figure 4, from the time between when the
elevator call button is pressed at the time of the record 411 and when the No. 1 elevator
car arrives and opens the door at the time of the record 412. Further, the number
of waiting travelers is calculated to be 4 from the difference between the number
of travelers at the time of door opening in the record 412 and the number of travelers
at the time of door closing in the record 413.
[0019] In a record 512, a waiting time of 17 seconds is calculated, based on the elevator
operation record data 111 in Figure 4, from the time between when the elevator call
button is pressed at the time of a record 414 and when a No. 2 elevator car arrives
and opens the door at the time of a record 417. Further, the number of waiting travelers
is calculated to be 2 from the difference between the number of travelers at the time
of door opening in the record 417 and the number of travelers at the time of door
closing in a record 419.
[0020] Figure 15 shows an example of the data of traveler elevator waiting time that is
calculated and output by the traveler elevator waiting time calculation unit 102.
This data is calculated from the temporary data in Figure 5. The statistic index value
of the waiting time is recorded for each elevator bank and each stop floor. Here,
assuming that the statistic index value is an average, 1501 shows that the average
waiting time is 43 seconds on the first floor when using a lower floor bank, and 1502
shows that the average waiting time is 40 seconds on the first floor when using a
higher floor bank.
[0021] Figure 14 shows an example of the data of traveler floor to floor travel time that
is calculated and output by the traveler floor to floor travel time calculation unit
103. This data is calculated from the temporary data shown in Figure 6. The statistic
index value of the floor to floor travel time from a reference floor to each stop
floor is recorded for each elevator bank. Here, assuming that the reference floor
is the first floor and the statistic index value is the average, 1401 shows that the
average travel time from the first floor to the second floor in the lower floor bank
is 16 seconds. 1402 shows that the average travel time from the first floor to the
third floor by using the elevator in the lower floor bank is 31 seconds. 1403 shows
that the average travel time from the first floor to the seventh floor by using the
elevator in the higher floor bank is 39 seconds. 1404 shows that the average travel
time from the first floor to the eighth floor by using the elevator in the higher
floor bank is 54 seconds. Here, the travel time from the first floor to the second
floor and from the first floor to the third floor does not linearly increase because
the travel time changes in the case of traveling from the first floor to the third
floor, between when traveling directly to the third floor from the first floor without
stopping on the second floor and when traveling to the third floor after stopping
at the second floor depending on travelers on the same elevator, due to the stopping
time on the second floor, the acceleration and deceleration time for stopping at the
second floor, and the like. The calculation method of the travel time in the traveler
floor to floor travel time calculation unit 103 will be described in detail below.
[0022] Figure 6 shows the data obtained by calculating the number of travelers getting on
the floor to floor elevator and travelling between floors as well as the travel time,
as intermediate data used to calculate the traveler floor to floor travel time, in
the traveler floor to floor travel time calculation unit 103 from the elevator operation
record data 111. A column 601 shows the departure floor of floor to floor travel,
a column 602 shows the arrival floor of floor to floor travel, a column 603 shows
the time taken for each traveler to travel between floors by using the elevator, and
a column 604 shows the number of travelers traveled. The floor to floor travel time
may also include the door opening/closing time and the standby time in the elevator,
in addition to the elevator operation time.
[0023] Further, it is assumed that the number of travelers is the number of travelers when
the door opens on the departure floor or the number of travelers when the door closes
on the arrival floor.
[0024] The calculation method of each record in Figure 6 will be described with reference
to Figure 4.
In a record 611, an operation time of 10 seconds is calculated, based on the elevator
operation record data 111 in Figure 4, from the time between when the No. 1 car closes
the door and starts from the first floor at the time of the record 413 and when the
No. 1 car arrives at the second floor and closes the door at the time of a record
415. At this time, the number of travelers is 4.
[0025] In a record 612, an operation time of 15 seconds is calculated, based on the elevator
operation record data 111 in Figure 4, from the time between when the No. 1 car closes
the door and starts from the second floor at the time of a record 416 and when the
No. 1 car arrives at the fourth floor and opens the door at the time of a record 418.
At this time, the number of travelers is 1.
[0026] In a record 613, an operation time of 20 seconds is calculated, based on the elevator
operation record data 111 in Figure 4, from the time between when the No. 2 car closes
the door and starts from the first floor at the time of the record 419 and when arriving
at the fourth floor and opening the door at the time of the record 412. At this time,
the number of travelers is 2.
[0027] In a record 614, an operation time of 20 seconds is calculated, based on the elevator
operation record data 111 in Figure 4, from the time between when the No. 1 car closes
the door and starts from the fourth floor at the time of a record 420 and when arriving
at the first floor and opening the door at the time of a record 423. At this time,
the number of travelers is 0.
[0028] Figure 7 is a diagram showing an example of the traveler travel line data. The travel
line data is the data showing the connection relationship in the travel network in
the building, such as between the elevator hall and the building entrance or office
entrance. Figure 7 shows the traveler travel line data in a multi-bank system building,
showing that travelers can directly move from the first-floor entrance of the building
to the lower floor bank and the higher floor bank. Here, only the entrance and the
elevator banks are selected as targets for the travel line. However, it is also possible
to select various facilities and equipment as targets, such as restaurants, observation
rooms, shops, restrooms, and smoking rooms located in the building. The explicit input
may be omitted, without inputting the data as shown in Figure 7, by taking into account
the travel line in the processing unit or the like.
[0029] The description of the data ends here.
<Description of the processing unit>
[0030] The method of calculating the statistic index value of traveler floor to floor travel
will be described with reference to Figure 2.
[0031] As described with reference to Figure 14, the floor to floor travel time by elevator
greatly varies depending on stops at intermediate floors. Figure 16 shows a graph
comparing the operation time between the case of direct operation from the first floor
to the third floor and the case of stopping at the second floor, in which the change
in the operation time due to stop at the intermediate floor is described. A vertical
axis 1602 of the graph represents the position in the height direction as well as
the floor number, and a horizontal axis 1601 represents the time. When starting from
the first floor at time of 1603 to travel to the third floor in direct operation,
the elevator arrives at the third floor at the time of 1604. On the other hand, when
the elevator stops at the second floor, it takes time in the respective periods of
deceleration for stopping at the second floor, stopping time at the second floor,
and acceleration for going from the second floor to the third floor. It can be found
that the presence or absence of the elevator stopping at intermediate floors depends
on the destination of other travelers on the same elevator, and that the traveler
travel time also varies depending on the number of stops at intermediate floors. The
description of the change in the operation time due to elevator stop at intermediate
floors ends here.
[0032] When considering the average travel time of floor to floor travel, it is necessary
to take into account the number of stops at intermediate floors. Thus, the processing
unit is designed to establish operation patterns showing combinations of intermediate
stop floors at which the elevator stops just before stopping at the arrival floor,
and express the travel time of each operation pattern as the sum of the average travel
time in the case of direct operation from the intermediate stop floor to the destination
floor, and the average travel time from the departure floor to the intermediate stop
floor, to obtain the average travel time from the departure floor to the destination
floor by the weighted average of the number of travelers from the intermediate stop
floor to the destination floor.
[0033] As an example, Figure 2 shows an operation pattern from the first floor to the third
floor as well as an operation pattern from the first floor to the fourth floor. The
movement indicated by the solid arrow shows direct operation and the movement indicated
by the dashed arrow shows that the elevator can stop at intermediate floors.
[0034] As described above, there are two patterns in the operation from the first floor
to the third floor. The average travel time from the first floor to the third floor
is obtained by the weighted average of the number of users with respect to the travel
time of each operation pattern. A more specific calculation method of the average
travel time from the first floor to the third floor is as follows. That is, the average
travel time from the first floor to the third floor in a movement 214, as well as
the sum of the average travel time of a movement 223 from the first floor to the second
floor and the average travel time of a movement 215 from the second floor to the third
floor are weight-averaged by the number of travelers arriving at the third floor in
each movement.
[0035] Similarly, there are three patterns in the operation from the first floor to the
fourth floor. The average travel time from the first floor to the fourth floor is
calculated by the weighted average of the number of users with respect to the travel
time in each operation pattern. A more specific calculation method of the average
travel time from the first floor to the fourth floor is as follows. That is, the average
travel time from the first floor to the fourth floor, the sum of the average travel
time of a movement 221 from the first floor to the second floor and the average travel
time of a movement 212 from the second floor to the fourth floor, and the sum of the
average travel time of a movement 222 from the first floor to the third floor and
the average time of a movement 213 from the third floor to the fourth floor are weight-averaged
by the number of travelers arriving at the fourth floor in each movement.
[0036] As a prerequisite for the calculation of the average travel time, it is assumed that
the travel time in each floor is independent unless the floors between which the elevator
moves overlap such as from the first floor to the third floor and from the third floor
to the fifth floor. Based on this assumption, it is possible to calculate the average
travel time from the departure floor to the arrival floor by adding the average travel
time from the departure floor to an intermediate stop floor and the average travel
time from the intermediate stop floor to the arrival floor. Further, assuming that
the travel time in each floor is independent, not only average but also dispersion
can be obtained by the same procedure. Note that it is possible to obtain the average
travel time from the departure floor to the intermediate stop floor, which is necessary
for the calculation assumption, by recursively calculating the average travel time
from the departure floor to the arrival floor (the intermediate stop floor) with the
intermediate stop floor as the destination floor, or by sequentially calculating the
average travel time by defining the calculation order in which each floor nearest
the reference floor is defined as arrival floor.
[0037] This calculation method is shown in Figure 17 as recurrence formula.
[0038] Figure 3 is a diagram showing the outline of the process and data flow with respect
to an example of the traveler travel condition output device according to the present
invention. The process and data flow will be described with reference to Figure 3.
[0039] The floor travel time calculation unit 101 reads a distance 302 from the doorway
to the elevator hall from the layout data 111, calculates a floor travel time 303
from the average human walking speed previously set as the distance (for example,
4 km/h), and outputs the result to the travel flow output unit 104.
[0040] The traveler elevator waiting time calculation unit 102 reads the elevator operation
record data 112, calculates a traveler elevator waiting time 304 through conversion
to the intermediate data shown in Figure 5, and outputs the result to the travel flow
output unit 104.
[0041] The traveler floor to floor travel time calculation unit 103 reads the elevator operation
record data 112, calculates a traveler floor to floor travel time 305 through conversion
to the intermediate data shown in Figure 6, and outputs the result to the travel flow
output unit 104.
[0042] The travel flow output unit 104 receives the floor travel time 303 output from the
floor travel time calculation unit 101, the traveler elevator waiting time 304 output
from the traveler elevator waiting time calculation unit 102, and the traveler floor
to floor travel time 305 output from the traveler floor to floor travel time calculation
unit 103, and arranges the input data into a building travel time table which is intermediate
data shown in Figure 14. The travel flow output unit 104 further draws a travel flow
306 from the building travel time table and outputs the result to the travel line
data 113.
[0043] In other words, the travel time calculation section (the floor travel time calculation
unit 101, the elevator waiting time calculation unit 102, and the floor to floor travel
time calculation unit 103) of the traveler travel condition output device 100 obtains,
for each user, a first travel time taken for the user to move from entering the building
to arriving at the elevator hall (floor transfer time), a waiting time in the elevator
hall from when the user arrives at the elevator hall to when the user gets on an elevator
(traveler elevator waiting time), and a second travel time taken for the user to move
from getting on the elevator to arriving at the destination floor (traveler floor
to floor travel time), and collecting the information of the first travel time, the
waiting time, and the second travel time to calculate the travel time statistical
information of the user from entering the building to arriving at the destination
floor. The display unit (travel flow comparison display unit 105) displays the total
travel time. The travel time calculation unit calculates the travel time statistical
information in the first elevator structure as well as the travel time statistical
information in the second elevator structure. The display unit displays the travel
time statistical information in the first elevator structure, together with the travel
time statistical information in the second elevator structure.
[0044] Further, the travel time calculation section may calculates the maximum value, average,
or dispersion of the time obtained by summing up the information of the first travel
time, waiting time, and second travel time of the user, as the travel time statistical
information.
[0045] Further, the first elevator structure may mean that the elevator directly goes from
the reference floor to the destination floor, and the second elevator structure may
mean that the elevator stops at intermediate floors, in addition to the destination
floor, in the operation of going from the reference floor to the destination floor
(an example will be described below with reference to Figure 10).
[0046] Further, the travel time calculation section may also calculate the average of the
time taken for travelers to move from a reference floor to a destination floor, by
obtaining a weighted average of the travel time from the reference floor to the destination
floor, by dividing the sum of the value weighted by multiplying the elevator operation
time when the elevator directly goes from the reference floor to the destination floor
with the number of users, and the value weighted by multiplying the travel time when
the elevator stops at intermediate floors in the operation of going from the reference
floor to the destination floor with the number of users moving through each floor,
by the total number of users directly going from each intermediate floor and the reference
floor to the destination floor.
[0047] Further, the display unit may display the travel flows showing the traveler elevator
waiting time, the elevator floor to floor travel time, and the door opening time at
each floor, by changing one or both of color and line type so that the displayed travel
flows can be identified by type.
[0048] Further, the second elevator structure may be defined such that any one or more of
the following elements are changed with respect to the first elevator structure: the
elevator layout, the number of elevators, the layout specification, and the traveler
travel demand.
[0049] Further, the display unit may set one or more reference values in advance for the
required time to transfer between any two points and states, check the required time
of the travel flow against the reference value, and display the travel flow by changing
one or both of color and line type.
[0050] Further, in the travel time calculation section, the second travel time is calculated
based on the operation record data obtained from an operation management system (not
shown). The operation record data may use one or both of the record data of physical
operation of the elevator and the past record data of virtual operation such as computer
simulation of the elevator (which will be described in detail below in Example 2).
[0051] Further, the first elevator structure and the second elevator structure include either
the building using the sky-lobby system in which travelers are expected to move by
changing elevators, or the multi-bank system in which the elevator bank to be used
varies depending on the destination floor (which will be described in detail below
in Example 3).
[0052] The description of the process and data flow ends here.
<Output and effects>
[0053] The travel flow 306 output by the travel flow output unit 104 will be described with
reference to Figures 9, 10, 11, and 13.
[0054] The graph in Figure 9 is a travel flow showing the movement from the building entrance
to an office entrance which can be the movement destination in each floor. A vertical
axis 951 represents the position (floor) in the height direction, and the horizontal
axis represents the travel time from the building entrance in which the building entrance
is defined as 0. The time of the travel flow is assumed to be the statistic index
value such as the average and maximum value of the travel time of each individual
traveler.
[0055] In the case of moving to lower floors, 901 represents the building entrance. After
departure from the building entrance, 902 represents arrival at the elevator hall
for lower floors. The time between 901 and 902 represents the travel time from the
building entrance to the lower-floor elevator hall, which is drawn by using the floor
travel time 303 calculated by the floor travel time calculation unit 101. Travelers
wait for elevator arrival at the elevator hall, and 903 represents elevator arrival.
Here, the period from 902 to 903 represents the time from when the travelers arrived
at the lower-floor elevator hall to when the elevator arrived, which is drawn by using
the traveler elevator waiting time 304 calculated by the traveler elevator waiting
time calculation unit 102. When the elevator arrived at 903, the travelers get on
the elevator and 904 represents elevator departure. The elevator starts at 904. 905
represents elevator arrival at the second floor and 906 represents elevator departure
after travelers get on and off the elevator at the second floor. Similarly, with respect
to the subsequent stop floors, 907 to 914 represent departure and arrival, sequentially,
at each floor until the elevator arrives at the highest floor. The line showing the
departure and arrival is drawn by using the traveler floor to floor travel time 305
calculated by the traveler floor to floor travel time calculation unit 103. Further,
it is also shown that, after the elevator stops at each floor, each traveler getting
off the elevator arrives at the destination on the floor. In the case of the second
floor, the traveler gets off the elevator between 905 and 906, and 915 represents
that the traveler's arrival at the destination on the second floor. The destination
arrival is represented by 916. Similarly, 917 to 919 represent destination arrival
on each floor. The line from the elevator stop to the destination arrival on each
floor is calculated using the floor travel time 303 calculated by the floor travel
time calculation unit 101.
[0056] In the case of moving to higher floors, 921 represents arrival at the elevator hall
for higher floors. Here, the travel flow line is slightly displaced in the vertical
axis direction so as not to overlap the lower-floor travel flow. However, the higher-floor
travel flow can also be displayed overlapping the lower-floor travel flow. Travelers
wait for elevator arrival at the elevator hall, and 922 represents elevator arrival.
When the elevator arrived at 922, the travelers get on the elevator and 923 represents
elevator departure. The elevator starts at 923. 924 represents elevator arrival at
the seventh floor, and 925 represents elevator departure after travelers get on and
off the elevator at the seventh floor. Similarly, with respect to the subsequent stop
floors, 926 to 931 represent departure and arrival, sequentially, at each floor until
the elevator arrives at the highest floor. Similar to the case of the lower floors,
it is also shown that, after the elevator stops at each floor, each traveler getting
off the elevator arrives at the destination on the floor, and 932 to 935 represent
destination arrival on each floor. It may also be possible to represent the destination
floor arrival or the destination arrival on each floor by connecting each point with
a line, without discriminating between lower floors and higher floors.
[0057] Figure 10 is a diagram of a simplified representation of the travel flow shown in
Figure 9, which shows only the arrival time at each floor. This can only show the
time when travelers can arrive at each floor, excluding detailed information. In the
comparison of travel flows or the like described below, the comparison may be easier
when detailed information is removed.
[0058] Figure 11 is a diagram in which information of the magnitude of the number of moving
travelers is added to the travel flow shown in Figure 9. The line segment thickness
is changed according to the number of travelers moving a specific range for each time
of the travel time and the elevator waiting time. For example, the thickness of the
line segment from 1122 to 1123 shows that the number of travelers who use the elevator
moving from the first floor to the seventh floor is more than 2500 and less than 5000
per hour. From this figure, it is possible to check where the travel time is long
and the number of users is large. In other words, the travel flow comparison display
unit 105 (display unit) can display the first travel time (floor transfer time), the
waiting time (traveler elevator waiting time), and the second travel time (traveler
floor to floor travel time) by weighting each of them based on the number of users.
[0059] Figure 13 is a diagram showing the travel flow when travelers move from each floor
to the building entrance. This travel flow is used to evaluate the flow of travelers
going to the entrance of the building, for example, when having lunch and leaving
their office. The vertical axis remains representing the position (floor) in the height
direction. However, the horizontal axis represents the time required to move from
each point to the building entrance, in which a building entrance 1300 is defined
as 0. For example, 1311 represents that the travel time from the movement start point
on the fifth floor to the building entrance is 128 seconds, and 1312 represents that
the travel time from taking the elevator down from the third floor is 66 seconds.
[0060] Figure 18 shows an example of outputting the result of the comparison of one or more
travel flows by the travel flow comparison display unit 105. The diagram of the comparison
result of the travel flows is described with reference to Figure 18. The travel flow
for the one-bank system that provides elevators programmed to stop at all floors is
indicated by 1801. In the multi-bank system in which elevators programmed to stop
at lower floors and elevators programmed to stop at higher floors are separately provided,
the travel flow for lower floors is indicated by 1802 and the travel for higher floors
is indicated by 1803. Here, as a result of comparison and evaluation without changing
the number of elevators and the specification in each system, it can be found that
the time taken to arrive at the destination is shorter in the one-bank system than
in the multi-bank system with respect to all stop floors. For example, it can be found
that 1812 which represents the arrival at the sixth floor in the multi-bank system
is faster than 1811 which represents the arrival at the sixth floor in the one-bank
system.
[0061] This example compares examples by changing the operation system. However, it is also
possible to compare the travel flows by changing only the elevator specification with
the same operation system, or by changing the number of elevator users or the use
conditions. In this way, by comparing the travel flows in various cases, it is possible
to intuitively know to what extent the travel time taken to each floor is improved
in each case.
[0062] Further, it may also be possible to compare the travel flow calculated from the operation
record data of an actual elevator installed in an actual building with the travel
flow calculated from the operation record data of the elevator by simulating the movement
of the elevator under the same and different conditions by using computer simulation
or other technique. In addition, it is also possible to evaluate the accuracy in estimating
the travel in the building by using computer simulation, by comparing the travel flow
calculated from the operation record data of the actual elevator with the travel flow
calculated under the same conditions by using computer simulation or other technique.
[0063] In other words, according to the present embodiment, it is possible to receive the
elevator operation record data and output the travel flow obtained by calculating
the time taken for travelers to move in the building. As a result, the time distance
of the whole building can be visualized by this travel flow. Further, by comparing
a plurality of travel flows obtained by calculating under different conditions, it
is possible to compare the time required for individual travelers to move in the whole
building. In particular, by comparing the travel flow obtained by calculation in computer
simulation with the travel flow obtained by calculation in actual elevator operation,
it is possible to evaluate the reproducibility by the computer simulation, regardless
of the trifling difference in the elevator operation.
<Example 2>
[0064] An example of the traveler travel condition output device and method according to
the present invention will be described below with reference to drawings. The basic
configuration of the device, data format, data and process flow, and the like, are
the same as those in Example 1, so that descriptions thereof will be omitted.
[0065] In this example, the elevator operation record data 111 to be received is different
from that in Example 1. This example uses travel record data of elevator based on
a destination floor reservation system, which is a system in which when a traveler
presses a button of destination floor from a terminal or other device provided in
or around the elevator hall, an elevator to stop at the pressed floor is indicated
to the traveler, without calling elevator by pressing the up and down button upon
boarding the elevator.
[0066] In the following, only the operation record data of the destination floor reservation
elevator is described with reference to Figure 12. Figure 12 shows an example of the
operation record data of elevator based on the destination floor reservation system.
In the destination floor reservation system, each individual traveler using an elevator
inputs the destination after arriving at the elevator hall before getting on the elevator,
so that the arrival time at the elevator hall, the departure floor, and the destination
floor are recorded in the operation record data of elevator of this system with respect
to each individual elevator user. The time at which the traveler operated the terminal
is recorded in a column 1201, the destination floor input to the terminal is recorded
in a column 1204, the floor on which the traveler operated the terminal (namely, the
departure floor) is recorded in a column 1207, and the elevator car number that the
terminal indicates to the traveler is recorded in a column 1205.
[0067] A record 1211 shows that a traveler who goes from the first floor to the second floor
operates the terminal at time 8:49:04 and is instructed to get on the No. 1 car. A
record 1212 shows that a traveler who goes from the first floor to the fourth floor
operates the terminal at time 8:49:10 and is instructed to get on the No. 1 car.
[0068] The traveler instructed to get on the No. 1 car by the terminal gets on the No. 1
car arriving just after the instruction. From a record 1215, it can be found that
the elevator on which the travelers of the records 1211 and 1212 will get arrives
at time 8:49:35. The description of the operation recode data ends here.
[0069] The method of calculating the traveler elevator waiting time from the operation record
data will be described. With respect to all travelers getting on elevator, the difference
between the terminal operation time and the elevator arrival time is calculated as
the waiting time of each traveler, and then the statistic index such as average is
calculated. The calculation result is output in the format of the traveler elevator
waiting time shown in Figure 15 in the same way as in Example 1. At this time, it
may also be possible to calculate the traveler elevator waiting time through the data
in Figure 5, similarly to Example 1. The description of the calculation method of
the traveler elevator waiting time ends here.
[0070] With the traveler travel condition output device and method of this example, it is
possible to output the travel flow that accurately reflects the traveler waiting time.
<Example 3 >
[0071] An example of the traveler travel condition output device and method according to
the present invention will be described below with reference to drawings. The basic
configuration of the device, data format, data and process flow, and the like are
the same as those in Example 1, so that descriptions thereof will be omitted.
[0072] In this example, the travel flow in a building using the sky-lobby system designed
to transfer a plurality of elevators will be described with reference to examples
in Figures 8 and 19.
[0073] Figure 8 is a diagram showing an example of the data in the sky-lobby system as the
traveler travel line data in Example 3. Figure 8 shows the traveler travel line data
in a sky-lobby type building, which shows that travelers can directly move to a lower
floor bank (802) from an entrance (801) on the first floor of the building, but it
is necessary to transfer to a shuttle bank (804) to go to a higher bank (805).
[0074] In the building in Fig. 19, a shuttle elevator going from the first floor to the
seventh floor, without stopping between floors, is provided, in which the seventh
floor corresponds to a sky-lobby floor. In the sky-lobby floor on the seventh floor,
an elevator bank programmed to stop at all floors from the first to seventh, as well
as an elevator bank programmed to stop at all floors from the twelfth to fifteenth
are provided. 1901 represents the arrival of the shuttle elevator at the first floor
and 1902 represents the arrival of the shuttle elevator at the seventh sky-lobby floor.
1903 represents traveler arrival at the elevator hall of the elevator bank programmed
to stop at all floors from the seventh to eleventh. 1902 and 1903 represent the movement
of the traveler arriving at the seventh floor to the elevator hall, which is drawn
by using the floor travel time 303 calculated by the floor travel time calculation
unit 101. 1904 represents the arrival of the elevator of the elevator bank programmed
to stop at all floors from the seventh to eleventh, at the seventh floor. 1903 and
1904 represent the traveler elevator waiting time from when the traveler arrives at
the elevator hall to when the elevator arrives, which is drawn by using the traveler
elevator waiting time 304 calculated by the traveler elevator waiting time calculation
unit 102. Further, 1905 represents traveler arrival at the elevator hall of the elevator
bank programmed to stop at the seventh floor and at all floors from the twelfth to
the fifteenth. 1902 to 1905 represent the movement of the traveler from arrival at
the seventh floor to the elevator hall, which is drawn by using the floor travel time
303 calculated by the floor travel time calculation unit 101. 1906 represents the
arrival of the elevator of the elevator bank programmed to stop at the seventh floor
and at all floors from the twelfth to the fifteenth, at the seventh floor. 1905 and
1906 represent the traveler elevator waiting time from when the traveler arrives at
the elevator hall to when the elevator arrives, which is drawn by using the traveler
elevator waiting time 304 calculated by the traveler elevator waiting time calculation
unit 102.
[0075] The description of the travel flow in the building using the sky-lobby system ends
here.
[0076] With the travel flow output by the traveler travel condition output device and method
of this example, the traveler travel condition output device and method can also be
applied to buildings designed to transfer a plurality of elevators.
