TECHNICAL FIELD
[0002] The present invention belongs to the technical field of rail transport, and more
particularly relates to a method and system for joint control of vehicle doors and
platform doors applied to high-speed railway.
BACKGROUND
[0003] With the development of rail transport, high-speed railway has become one of the
most important means of transportation in people's daily life. Which is, however,
accompanied by safety accidents that often occur between the platform and the track.
Therefore, installing platform doors systems on high-speed railway platforms is the
trend. Platform doors are mostly built in a platform area between a train entrance
and a train exit for separating the platform space from the train running space. After
a train arrives and stops in the platform area, platform doors are opened allowing
passengers to get on and off the train, and then are closed before the train is started.
Thus, platform doors can provide a safer ride for passengers. Due to actual operation
needs, various types of trains would stop at the station every day with each type
of train corresponding to a different requirement for opening and closing the platform
doors. Furthermore, situations of asymmetric forward and backward rides may arise,
which require the accurate determination of the side of platform doors that need to
be opened or closed according to the direction in which the station track receives
the train. Therefore, there is an urgent need for a platform doors control solution
that is compatible with a variety of train types and that can satisfy a variety of
train operation schemes.
[0004] In an existing high-speed railway platform doors control system (hereinafter platform
doors system), a ground device acquires train entrance and stopping accuracy information
through microwave carrier waves, and autonomously controls the opening and closing
of corresponding platform doors when determining that the related conditions are met.
While this solution is compatible with various types of trains and satisfies various
train operation schemes, it poses high requirements for the accuracy of determination
of the platform doors system itself. In particular, this solution requires that the
platform doors system can accurately determine a train's operation state and the door
side information of train doors to be opened or closed, and determine the timing for
controlling the platform doors to act, according to the speed and location of the
train. Once the platform doors system makes an erroneous judgement, the platform doors
may be mistakenly opened or closed, affecting the operation order and efficiency.
Therefore, there is a need to improve the stability and reliability of the platform
doors system, thereby improving the operation efficiency.
SUMMARY
[0005] In view of the above problems, the present invention provides a method and system
for joint control of vehicle doors and platform doors applied to high-speed railway.
[0006] There is provided a method for joint control of vehicle doors and platform doors
applied to high-speed railway. The method includes the following operations.
[0007] A vehicle-mounted device sends an open-or-close-vehicle-doors command to a first
ground device.
[0008] The first ground device determines a validity of the open-or-close-vehicle-doors
command, and performs a processing operation depending on the determination. The processing
operation includes the following operations.
[0009] If the open-or-close-vehicle-doors command is valid, the first ground device correctly
generates an open-or-close-platform-doors command according to the open-or-close-vehicle-doors
command, and the first ground device further decides whether to send the open-or-close-platform-doors
command to a second ground device depending on a monitored timing of the open-or-close-platform-doors
command.
[0010] If the open-or-close-vehicle-doors command is invalid, the open-or-close-vehicle-doors
command is discarded and subsequent processing actions are terminated.
[0011] The second ground device converts the open-or-close-platform-doors command received
from the first ground device into a platform-doors-relay-driving command recognizable
by a platform doors system, and sends the platform-doors-relay-driving command to
the platform doors system.
[0012] After the recognizable platform-doors-relay-driving command is received, the platform
doors system performs an open-or-close-platform-doors action.
[0013] The second ground device captures platform-doors-relay-state information, converts
the platform-doors-relay-state information into first platform doors state information
recognizable by the first ground device, and sends the first platform doors state
information to the first ground device.
[0014] The first ground device converts the first platform doors state information into
second platform doors state information recognizable by the vehicle-mounted device,
determines a validity of the second platform doors state information, and decides
whether to return the second platform doors state information to the vehicle-mounted
device depending on the determination. The first ground device may further decide
whether to return the second platform doors state information to the vehicle-mounted
device depending on a monitored timing for returning the second platform doors state
information.
[0015] Furthermore, the first ground device determines that the open-or-close-vehicle-doors
command is valid when following conditions are all simultaneously met.
[0016] A train stops still and accurately.
[0017] There are platform doors on a station track where the train stops.

according to the open-or-close-vehicle-doors command. This operation includes the
following conditions.
[0019] When the open-or-close-vehicle-doors command is directed to the train doors on the
left side, it is determined there is set up platform doors on the platform side corresponding
to the train doors on the left side.
[0020] When the open-or-close-vehicle-doors command is directed to the train doors on the
right side, it is determined that there is set up platform doors on the platform side
corresponding to the train doors on the right side.
[0021] When the open-or-close-vehicle-doors command is directed to the train doors on both
sides, it is determined that there is set up platform doors on both sides of a platform
of the station track where the train is located The open-or-close-vehicle-doors command
is directed to opening or closing trains doors on at least one side. This step includes
following conditions.
[0022] The train doors on the left side are command-free, and the train doors on the right
side are opened or closed.
[0023] The train doors on the left side are opened or closed, and the train doors on the
right side are command-free.
[0024] The train doors on the left side are opened or closed, and the train doors on the
right side are opened or closed.
[0025] Further, the operation of determining the platform doors side corresponding to the
train doors includes the following operations.
[0026] If the direction in which the station track receives the train is a forward direction,
the sides of the platform doors are consistent with the sides of the train doors.
[0027] If of the direction in which the station track receives the train is a backward direction,
the sides of the platform doors are opposite to the sides of the train doors.
[0028] Where the forward direction is a forward direction of a line, and the backward direction
is a backward direction of the line.

field, a turnback flag field, and an open-or-close-doors command field.
[0032] Further, the turn-back mark is generated by the vehicle- mounted device determining
whether the train turns back.
[0033] If the train turns back, the vehicle-mounted device generates an immediately-turn-back
flag.
[0034] If the train does not turn back, the vehicle-mounted device generates a not-immediately-turn-back
flag.
[0035] Further, the vehicle-mounted device determines whether the train turns back according
to mode changes of a currently servicing end and a non-currently servicing end, which
specifically includes the following.
[0036] When the currently servicing end switches from a non-sleep mode to a sleep mode so
that it descends to the non-currently servicing end, the non-currently servicing end
is switches from the sleep mode to the non-sleep mode so that it ascends to the currently
servicing end, then the vehicle-mounted device determines that the train turns back.
[0037] When modes of the currently servicing end and/or the non-currently servicing end
are not changed, then the vehicle-mounted device determines that the train does not
turn back.
[0038] Further, the operation that the first ground device decides whether to send the open-or-close-platform-doors
command to the second ground device depending on the monitored timing for sending
the open-or-close-platform-doors command includes the following operations.

the first ground device sends a message to the second ground device indicating that
there is no command directed to the corresponding platform doors, and then resets
the time threshold timer.
[0041] Each time the first ground device receives the open-or-close-vehicle-doors command
and determines that the open-or-close-vehicle-doors command is valid, the first ground
device sends the open-or-close-platform-doors command to the second ground device
and restarts the timing.
[0042] When the first ground device determines that its communication with the vehicle-mounted
device is interrupted, the first ground device regards a command for controlling platform
doors of the station track where the train is located as no command, and resets the
time threshold timer.
[0043] When the first ground device determines that its communication with the second ground
device is interrupted, the first ground device sets states of all platform doors of
a station corresponding to the second ground device to unknown states, sets a platform
doors control command to no command, and resets the time threshold timer.
[0044] Further, the operation the first ground device converts the first platform doors
state information into the second platform doors state information recognizable by
the vehicle-mounted device includes the following.
[0045] The first ground device generates second platform doors state information corresponding
to the open-or-close-vehicle-doors command based on the first platform doors state
information, the open-or-close-vehicle-doors command, and the platform doors database
stored by the first ground device.
[0046] Further, the operation of deciding whether to return the second platform doors state
information to the vehicle-mounted device depending on the determination includes
the following.
[0047] When it is determined that the second platform doors state information is valid,
the first ground device immediately returns the second platform doors state information
to the vehicle-mounted device as an acknowledgement of the open-or-close-vehicle-doors
command.
[0048] When it is determined that the second platform doors state information is invalid,
the first ground device does not return information to the vehicle-mounted device.
[0049] Further, the operation that the first ground device determines the validity of the
second platform doors state information includes the following.
[0050] When the open-or-close-vehicle-doors command is directed to the train doors on the
left side while the train doors on the right side are command-free, it is determined
that the second platform doors state information is valid when the platform doors
corresponding to the train doors on the left side are in an open or closed state;
[0051] When the train doors on the left side are command-free while the open-or-close-vehicle-doors
command is directed to the train doors on the right side, it is determined that the
second platform doors state information is valid when the platform doors corresponding
to the train doors on the right side are in an open or closed state.
[0052] When the open-or-close-vehicle-doors command is directed to the train doors on both
sides, it is determined that the second platform doors state information is valid
when the platform doors corresponding to the train doors on the left side are in an
open or closed state and the platform doors corresponding to the train doors on the
right side are in an open or closed state.
[0053] Further, the operation that the first ground device further decides whether to return

[0093] The present invention provides a method for joint control of vehicle doors and platform
doors applied to high-speed railway. The method includes the following operations.
[0094] A vehicle-mounted device sends an open-or-close-vehicle-doors command to a first
ground device.
[0095] The first ground device determines a validity of the open-or-close-vehicle-doors
command, and performs a processing operation depending on the determination. The processing
operation includes the following.
[0096] If the open-or-close-vehicle-doors command is valid, an open-or-close-platform-doors
command is correctly generated according to the open-or-close-vehicle-doors command,
and the first ground device decides whether to send the open-or-close-platform-doors
command to a second ground device depending on a monitored timing for sending the
open-or-close-platform-doors command.
[0097] If the open-or-close-vehicle-doors command is invalid, the open-or-close-vehicle-doors
command is discarded and subsequent processing actions are terminated.
[0098] The second ground device converts the open-or-close-platform-doors command received
from the first ground device into a platform-doors-relay-driving command recognizable
by a platform doors system, and sends the platform-doors-relay-driving command to
the platform doors system.
[0099] After the recognizable platform-doors-relay-driving command is received, the platform
doors system performs an open-or-close-platform-doors action.
[0100] The second ground device captures platform-doors-relay-state information, converts
the platform-doors-relay-state information into first platform doors state information
recognizable by the first ground device, and sends the first platform doors state
information to the first ground device.
[0101] The first ground device converts the first platform doors state information into
second platform doors state information recognizable by the vehicle-mounted device,
determines a validity of the second platform doors state information, and decides
whether to return the second platform doors state information to the vehicle-mounted
device depending on the determination, and the first ground device can further decide
whether to return the second platform doors state information to the vehicle-mounted
device depending on a monitored timing for returning the second platform doors state
information.
[0102] Embodiments of the present invention will be described in detail with reference to
FIG. 1. FIG. 1 is a data flow diagram of a method for joint control of vehicle doors
and platform doors according to the present invention. As shown in FIG. 1, the method
is described as follows.
[0103] The vehicle-mounted device sends an open-or-close-vehicle-doors command to the first
ground device.
[0104] The first ground device determines a platform doors side corresponding to train doors
according to the open-or-close-vehicle-doors command. This step includes following
steps. The first ground device verifies that the open-or-close-vehicle-doors command
is valid, then stores this command and performs the subsequent processing, otherwise,
the first ground device discards this command and terminates the subsequent processing,
so as to improve safety of an action of the platform doors. Specifically, the open-or-close-vehicle-doors
command is determined to be valid only when following conditions are met simultaneously.
- 1. A train stops still and accurately.
- 2. There are platform doors on a station track where the train stops.
- 3. A platform doors side corresponding to train doors is determined according to the
open-or-close-vehicle-doors command. This step includes following steps.
[0105] When the open-or-close-vehicle-doors command is directed to the train doors on the
left side, it is determined that there is set up platform doors on the platform side
corresponding to the train doors on the left side.
[0106] When the open-or-close-vehicle-doors command is directed to the train doors on the
right side, it is determined that there is set up platform doors on the platform side
corresponding to the train doors on the right side.
[0107] When the open-or-close-vehicle-doors command is directed to the train doors on both
sides, it is determined there is set up platform doors on both sides of a platform
of the station track where the train is located.
[0108] 4. The open-or-close-vehicle-doors command is directed to opening or closing trains
doors on at least one side. The step includes following scenarios.
[0109] The train doors on the left side are command-free, and the train doors on the right
side are open or closed.
[0110] The train doors on the left side are open or closed, and the train doors on the right
side are command-free.
[0111] The train doors on the left side are open or closed, and the train doors on the right
side are opened or closed.
[0112] All of above conditions must be satisfied, otherwise it is determined that the open-or-close-vehicle-doors
command is invalid, and the first ground device does not covert or send the open-or-close-vehicle-doors
command.
[0113] Furthermore, the step of determining the platform doors side corresponding to the
train doors includes following steps.
[0114] If the direction in which the station track receives the train is a forward direction,
the sides of the platform doors are consistent with the sides of the train doors.
[0115] If the direction in which the station track receives the train is a backward direction,
the sides of the platform doors side are opposite to the sides of the train doors.
[0116] The forward direction is a forward direction of a line, and the backward direction
is a backward direction of the line. The open-or-close-vehicle-doors command sent
by the vehicle-mounted device contains the direction in which the station track receives
the train, and the first ground device directly accepts the information. The vehicle-mounted
device knows whether the current train operates in the forward direction or in the
backward direction according to a train orientation of a cab activated by the vehicle-mounted
device with respect to a Last Related Balise Group (LRBG) direction.
[0117] The first ground device verifies that the open-or-close-vehicle-doors command is
valid, then stores this command, and generates a corresponding open-or-close-platform-doors
command according to the open-or-close-vehicle-doors command in conjunction with a
platform doors database stored by the first ground device. The open-or-close-vehicle-doors
command includes a train carriages grouping type field, a vehicle station track receiving
vehicle direction field, a turnback flag field, and an open-or-close-doors command
field. According to actual operation needs, the train grouping includes various types,
such as 8 carriages grouping, 16 carriages grouping, and 18 carriages grouping, but
it is not limited to that. When platform doors are set in the station, it will consider
all current possible operation scenarios. Therefore, the first ground device accurately
generates the corresponding open-or-close-platform-doors command (positions and the
number of platform doors, and platform doors are closely arranged) according to the
actual grouping type of the train, so as to ensure the safety of the system and order
of the operation. Exemplarily, the train grouping is described using 8 carriages grouping,
16 carriages grouping and 18 carriages grouping as an example, and the specific solution
is shown in the following table.

[0118] It is to be noted that the solution of the present invention in which the open-or-close-platform-doors
command is generated according to the open-or-close-vehicle-doors command has stronger
flexibility, and in addition to situations listed in the table, supports expansion
of more train grouping types. The vehicle-mounted device needs to determine whether
the current train is turned back to generate the turn-back flag in the table. The
turn-back flag includes an immediately-turn-back flag and a not-immediately-turn-back
flag. The determining method is to set a currently servicing end (in a non-sleep mode)
at one end of the train and set a non-currently servicing end (in a sleep mode) at
the other end of the train. In fact, the currently servicing end and the non-currently
servicing end are two working states of vehicle-mounted devices on two train heads.
Exemplarily, using the Beijing-Shanghai high-speed railway as an example, when the
train drives from Beijing to Shanghai, the vehicle-mounted device on the train head
1 is the currently servicing end and is in the non-sleep mode, and it works normally
to monitor the safe operation of the train, while the vehicle-mounted device on the
train head 2 is the non-currently servicing end and is in the sleep mode, and it does
not execute any train safety protection function. When the train is driven from Shanghai
to Beijing, the train turns back, and the currently servicing end and the non-currently
servicing end are switched. That is, the vehicle-mounted end on the train head 2 becomes
the currently servicing end and is in in the non-sleep mode, and it works normally
to monitor the safe operation of the train, while the vehicle-mounted device on the
train head 1 becomes the non-currently servicing end and is in the sleep mode, and
it does not execute any train safety protection function.
[0119] When following conditions are simultaneously satisfied, the vehicle-mounted device
determines that the train turns back and the turn-back mark is generated.
[0120] The original currently servicing end switches to the sleep mode and descends to the
non-currently servicing end.
[0121] The original non-currently servicing end switches out of the sleep mode and ascends
to the currently servicing end.
[0122] Otherwise, it is determined that the train does not turn back, and the not-immediately-turn-back
flag is generated.
[0123] Problems that the communication network is interrupted or the communication data
is lost may exist, and the action of the platform doors system needs time. Therefore,
in order to improve the reliability and safety of the system, before the first ground
device sends the open-or-close-platform-doors command to the second ground device,
the first ground device needs to monitor the timing for sending the open-or-close-platform-doors
command. The specific steps of monitoring the timing for sending the open-or-close-platform-doors
command are as follows.
- 1. The first ground device keeps sending the open-or-close-platform-doors command
to the second ground device, for a period of time. Exemplarily, the period of time
for sending is set to T.
- 2. When a preset time threshold T set by a time threshold timer is exceeded, the first
ground device sends a message to the second ground device indicating that there is
no command directed to the corresponding platform doors and resets the time threshold
timer.
- 3. Each time the first ground device receives the open-or-close-vehicle-doors command
and determines that the open-or-close-vehicle-doors command is valid, the first ground
device sends the open-or-close-platform-doors command to the second ground device
and restarts the timing T.
- 4. If the first ground device determines that its communication with the vehicle-mounted
device is interrupted, for the sake of safety, the first ground device regards a command
for controlling platform doors of the station track where the train is located as
no command, and resets the time threshold timer.
- 5. If the first ground device determines that its communication with the second ground
device is interrupted, for the sake of safety, the first ground device sets states
of all platform doors of a station corresponding to the second ground device to unknown
states, a platform door control command is set to no command, and the time threshold
timer is reset.
[0124] When the open-or-close-platform-doors command meets the sending timing, the first
ground device sends the open-or-close-platform-doors command to the second ground
device. The second ground device converts the open-or-close-platform-doors command
into the platform-doors-relay-driving command recognizable by the platform doors system,
and sends the platform-doors-relay-driving command to the platform doors system. The
platform doors system specifically executes the doors open/close action.
[0125] The second ground device keeps collecting a platform doors relay state, and converts
the platform-doors-relay-state information into first platform doors state information
and sends the first platform doors state information to the first ground device. The
first ground device generates second platform doors state information according to
the first platform doors state information, the open-or-close-vehicle-doors command
and the platform doors database stored by the first ground device, and sends the second
platform doors state information to the vehicle-mounted device. Before the first ground
device feeds back the second platform doors state information to the vehicle-mounted
device, the validity of the second platform doors state information needs to be determined,
or the timing for returning the second platform doors state information is monitored.
[0126] Specifically, the situation in which the validity of the second platform doors state
information is determined is as follows.
- 1. When the open-or-close-vehicle-doors command is directed to the train doors on
the left side while the train doors on the right side are command-free, it is determined
that the second platform doors state information is valid when the platform doors
corresponding to the train doors on the left side are in an open or closed state.
- 2. When the train doors on the left side are command-free while the open-or-close-vehicle-doors
command is directed to the train doors on the right side, it is determined that the
second platform doors state information is valid when the platform doors corresponding
to the train doors on the right side are in an open or closed state.
- 3. When the open-or-close-vehicle-doors command is directed to the train doors on
both sides, determining that the second platform doors state information is valid
when the platform doors corresponding to the train doors on the left side are in an
open or closed state and the platform doors corresponding to the train doors on the
right side are in an open or closed state.
[0127] The step of monitoring the timing for returning the second platform doors state information
is as follows.
[0128] The first ground device keeps sending the open-or-close-platform-doors command to
the second ground device, for a period of time. Exemplarily, the period of time for
sending is set to T.
[0129] In the time of T, if it is determined that platform doors move in place, the first
ground device immediately feeds back the second platform doors state information to
the vehicle-mounted device as a feedback of the open-or-close-vehicle-doors command.
[0130] When the time of T is exceeded, the first ground device does not return information
to the vehicle-mounted device.
[0131] If the first ground device determines that its communication with the second ground
device is interrupted, the states of the platform doors are reset to unknown states.
[0132] Furthermore, it is determined that the platform doors move in place only in following
situations.
- 1. When the open-or-close-vehicle-doors command is directed to opening the train doors
on the left side while the train doors on the right side are command-free, it is determined
that the platform doors move in place when the platform doors corresponding to the
train doors on the left side are in an open state.
- 2. When the open-or-close-vehicle-doors command is directed to closing the train doors
on the left side while the train doors on the right side are command-free, it is determined
that the platform doors move in place when the platform doors corresponding to the
train doors on the left side are in a closed state.
- 3. When the train doors on the left side are command-free while the open-or-close-vehicle-doors
command is directed to opening the train doors on the right side, it is determined
that the platform doors move in place when the platform doors corresponding to the
train doors on the right side are in an open state.
- 4. When the train doors on the left side are command-free while the open-or-close-vehicle-doors
command is directed to closing the train doors on the right side, it is determined
that the platform doors move in place when the platform doors corresponding to the
train doors on the right side are in a closed state.
- 5. When the open-or-close-vehicle-doors command is directed to opening the train doors
on the left side and opening the train doors on the right side, it is determined that
the platform doors move in place when the platform doors corresponding to the train
doors on the left side are in an open state and the platform doors corresponding to
the train doors on the right side are in an open state.
- 6. When the open-or-close-vehicle-doors command is directed to opening the train doors
on the left side and closing the train doors on the right side, it is determined that
the platform doors move in place when the platform doors corresponding to the train
doors on the left side are in an open state and the platform doors corresponding to
the train doors on the right side are in closed state.
- 7. When the open-or-close-vehicle-doors command is directed to closing the train doors
on the left side and opening the train doors on the right side, it is determined that
the platform doors move in place when the platform doors corresponding to the train
doors on the left side are in closed state and the platform doors corresponding to
the train doors on the right side are in an open state.
- 8. When the open-or-close-vehicle-doors command is directed to closing the train doors
on the left side and closing the train doors on the right side, it is determined that
the platform doors move in place when the platform doors corresponding to the train
doors on the left side are in a closed state and the platform doors corresponding
to the train doors on the right side are in a closed state.
[0133] When the second platform doors state information is valid or the second platform
doors state information meets the feedback timing, the first ground device feeds back
the second platform doors state information to the vehicle-mounted device as an acknowledgement
of the open-or-close-vehicle-doors command.
[0134] In FIG. 1, the NOP refers to "no operation", and the "reset" refers to that the open-or-close-vehicle-doors
command is reset to no command, the open-or-close-platform-doors command is reset
to no command, and the platform door state is reset to the unknown state.
[0135] The present invention provides a system for joint control of vehicle doors and platform
doors applied to a high-speed railway. The system includes a vehicle-mounted device,

command is correctly generated according to the open-or-close-vehicle-doors command,
and the first ground device decides whether to send the open-or-close-platform-doors
command to the second ground device depending on a monitored timing for sending the
open-or-close-platform-doors command.
[0140] If the open-or-close-vehicle-doors command is invalid, the open-or-close-vehicle-doors
command is discarded and subsequent processing actions are terminated.
[0141] The first ground device being further configured to convert the first platform doors
state information into the second platform doors state information recognizable by
the vehicle-mounted device and decide whether to return the second platform doors
state information to the vehicle-mounted device includes the following.
[0142] The first ground device decides whether to return the second platform doors state
information to the vehicle-mounted device depending on the validity of the second
platform doors state information, and can further be configured to decide whether
to return the second platform doors state information to the vehicle-mounted device
depending on the monitored timing for returning the second platform doors state information.
[0143] The second ground device is configured to convert the open-or-close-platform-doors
command into a platform-doors-relay-driving command recognizable by the platform doors
system and send the platform-doors-relay-driving command to the platform doors system,
and is further configured to collect and convert the platform-doors-relay-state information
into the first platform doors state information and send the first platform doors
state information to the first ground device.
[0144] The platform doors system is configured to perform an open-or-close-platform-doors
action.
[0145] In this system, the first ground device bears a key role, and it needs to correctly
generate the open-or-close-platform-doors command according to the open-or-close-vehicle-doors
command, so as to ensure the correctness of the open-or-close-platform-doors command;
it needs to determine the timing for sending the open-or-close-platform-doors command

doors system, so as to allow the vehicle-mounted device and the train driver to accurately
know the condition of the joint control of the vehicle doors and platform doors in
time for taking further measures.
[0146] FIG. 2 is a schematic diagram of a system according to the present invention. As

wired communication manner: the first ground device sends the open-or-close-platform-doors
command to the second ground device, and the second ground device sends the first
platform doors state information to the first ground device.
[0149] A relay interface is performed between the second ground device and the platform
doors system in a wired manner: the second ground device sends the platform-doors-relay-driving
command to the platform doors system and collects the platform-doors-relay-state information.
[0150] FIG. 3 is a block diagram illustrating the internal modules of a first ground device
of the system according to the present invention. As shown in FIG. 3, the first ground
device includes an open-or-close-vehicle-doors command verifying and storing module,

command sending module, an open-or-close-platform-doors command sending timing monitoring
module, a platform doors state receiving and storing module, a platform doors state
converting module, a platform doors state sending module and a platform doors state
feedback timing monitoring module. Specifically, the open-or-close-vehicle-doors command
verifying and storing module verifies the open-or-close-vehicle-doors command after
receiving the open-or-close-vehicle-doors command and stores and sends the open-or-close-vehicle-doors
command to the open-or-close-platform-doors command generating module after determining
that the open-or-close-platform-doors command is valid. The open-or-close-platform-doors
command generating module converts the open-or-close-vehicle-doors command into the
corresponding open-or-close-platform-doors command and sends the open-or-close-platform-doors
command to the open-or-close-platform-doors command sending module. The open-or-close-platform-doors
command sending timing monitoring module determines whether the open-or-close-platform-doors
command meets the sending timing and sends the open-or-close-platform-doors command
to the open-or-close-platform-doors command sending module depending on the determination.
The open-or-close-platform-doors command sending module is configured to send the
open-or-close-platform-doors command to the second ground device when the open-or-close-platform-doors
command sending timing monitoring module determines that the open-or-close-platform-doors
command needs to be sent.
[0151] The platform doors state receiving and storing module receives and stores the first
platform doors state information sent from the second ground device and sends the
first platform doors state information to the platform doors state converting module.
The platform doors state converting module converts the first platform doors state
information into second platform doors state information corresponding to the open-or-close-vehicle-doors
command. The platform doors state feedback timing monitoring module is configured
to determine the validity of the second platform doors state information and whether
the second platform doors state information meets the feedback timing and sends the
second platform doors state information to the platform doors state sending module.
The platform doors state sending module is configured to return the second platform
doors state information to the vehicle-mounted device when the platform doors state
feedback timing monitoring module determines that the second platform doors state
information needs to be fed back.
[0152] It is to be noted that in the present invention, the first ground device and the
second ground device can also be combined as one ground device, and this ground device
converts the open-or-close-vehicle-doors command sent by the vehicle-mounted device
into the corresponding platform-doors- relay-driving command; and the above functions
of the first ground device can also be integrated onto the vehicle-mounted device,
and the vehicle-mounted device directly sends the open-or-close-platform-doors command
to the second ground device.
[0153] In the present invention, the first ground device fully verifies the validity of
the received open-or-close-vehicle-doors command, monitors the timing for sending
the open-or-close-platform-doors command, and decides whether to return the platform
doors state to the vehicle-mounted device and monitors the feedback time according
to the state of the platform doors system, so that the reliability and the safety
of the system for joint control of vehicle doors and platform doors are improved,
thereby improving the efficiency of operation.
[0154] Although the present invention has been described in detail with reference to the
above-mentioned embodiments, it should be understood by those skilled in the art that
the technical solutions described in the above-mentioned embodiments may still be
modified, or part of the technical features therein may be equivalently substituted.
