[0001] The present invention relates to a queue management system suitable for use in controlling
the serving order of customers at, for instance, a supermarket counter, or the like.
The system might also be employed in pharmacy prescription dispensaries, hospital
and doctor's surgeries, cafes, restaurants and canteens although the present invention
should not be construed as being limited for use in any of the above. The queue management
system of the present invention may be used at any location where people have to wait
for any form of goods or service.
[0002] Queue management systems are well known in many situations, in particular at supermarket
counters. The systems currently in use employ interconnecting wiring between a staff-operated
signalling device and a customer display unit.
[0003] According to one aspect of the present invention there is provided a queue management
system comprising:
means actuable on arrival of a customer at a service point;
a display means for displaying an indication relating to a customer being served;
at least one remote control unit linked to the display means and capable of causing
an indication displayed by the display means to be updated; and
a processing unit adapted to process data received from the actuable means and the
display means and to provide information to enable the system to be monitored.
[0004] According to a second aspect of the present invention, there is provided a queue
management system comprising:
means actuable on arrival of a customer at a service point;
a display means for displaying an indication relating to a customer being served;
and
at least one remote control unit linked to the display means and capable of causing
information displayed by the display means to be updated;
wherein the link between the or each remote control unit and the display means is
"wireless" and comprises a receiver/transmitter arrangement.
[0005] The means actuable on arrival of a customer at a service point is preferably a dispensing
means for dispensing to a customer on arrival at a service point an indication of
their relative position in any queue at the service point. The dispensing means may
be a ticket dispenser, for example in the form of a printer. The dispenser is capable
of being actuated by a customer, for instance by operation of a button, to cause the
printer to issue a numbered ticket providing the customer with an indication of his/her
queue position. It is to be appreciated that the indication of queue position need
not be a number but could be some other recognisable character which would enable
the customer to determine his/her queue position, for instance a letter, or combination
of letters, of the alphabet. At present, it is preferred that the queue-position
indication is a number which is sequentially updated for each new customer arriving
at the dispenser.
[0006] Alternatively, the actuable means may be actuable by a customer (either directly
or indirectly) without dispensing a ticket. For example, the customer might enter
(or have entered on their behalf) an identification such as his/her name which is
then displayed on the display means when it is that person's turn to be served. The
actuable means might be actuable by, for example, something on the person of the customer,
such as a magnetic card or transmitter of some description.
[0007] The display means may be a conventional display unit having the capacity to display
a character or series of characters indicative of the queue-position being served
at the head of the queue. Typically, the displayed indication will be the number of
the ticket of the customer who has last been called for serving. This enables other
customers waiting to determine the number of people in the queue ahead of them. It
is within the scope of the present invention that the display unit displays other
information in relation to the status of the queue. For example, it may merely identify
the customer actually being called for serving.
[0008] Other display units may be provided as "slave" units on the main customer display.
Alternatively, or in addition, other remote display units could be provided at separate
locations, for instance in a manager's office. Such additional, or "slave" units,
could be connected to the main unit or could be updated directly by a signal from
one of the control units. The system may include means for indicating a change in
the information displayed. For example, the display may temporarily change colour,
or a display change may be accompanied by a chime. Typically, the display means will
be operated from the mains supply although it may include a battery-backed count memory
to avoid loss of information should the mains power be interrupted.
[0009] The or each remote control unit preferably includes a single button which causes
a signal to be sent to the display means to advance the display unit by one step (i.e.
one digit if the display is a numeral). The signal may be transmitted to the display
unit by conventional means, such as via a wire link. Alternatively, the arrangement
may be "wireless" with the link being constituted by a transmitter on the remote control
unit and a receiver on the display unit. The signal, in this embodiment, may be an
infra-red signal or any other form of electro-magnetic wave, for example a radio or
ultrasonic signal.
[0010] The main display means may be adapted to send signals to other remote displays, either
via a "wireless" arrangement similar to that described above or a conventional wire
link. Alternatively, secondary display units may be operated directly by a signal
from the or each remote control unit.
[0011] In the embodiment in which the remote control units are "wireless", each may be powered
by a battery for ease of handling. It is to be appreciated, however, that the remote
control unit may be powered from the mains supply.
[0012] In addition to the remote control units for operation by serving staff, there may
also be provided a master remote control unit capable of being operated by, for instance,
a manager or supervisor. This master remote control unit would be substantially the
same as the standard remote control units for operation by sales staff but might include
three separate buttons: a first button for advancing the count by one step on the
display (without any time delay between advances); a second button for a fast advance
of the display; and a third button to reset the display or displays to zero. As with
the standard remote control units, the master remote control unit may be rechargeable,
standard battery powered, or may be powered from the mains supply.
[0013] The processing unit is adapted to process data received from one or more of the dispensing
means, the remote control unit(s) and the display means. In many applications the
most important data for the processing unit to collect in order to enable monitoring
of the system are the time and number of each queue-position indication issued and
the time of serving of each sequential position at the head of the queue. This data
would allow the processing system to provide information as to the time taken to serve
customers during the day, variations in the length of the queue during the day, the
rate at which tickets are issued and a simple tally of the number of customers served
on each day. Moreover, this arrangement would enable a remote indication of a large
build-up of customers to be detected and this might allow the manager temporarily
to allocate extra staff to clear the backlog of customers.
[0014] Conveniently, the processing unit may be contained together in a single unit with
the dispensing means which controls the dispensing of queue-position indications.
The processing unit may collect data on the time at which each queue-position is served
directly from the remote control unit or via a transmission from the display unit.
[0015] For a better understanding of the present invention, and to show how the same may
be carried into effect, reference will now be made, by way of example, to the accompanying
drawing which illustrates schematically a queue management system in accordance with
the present invention.
[0016] The queue management system shown in the figure comprises a dispensing means 1 for
dispensing to a customer a queue-position indication, a main display means 2 for displaying
information in relation to the service position at the head of the queue, "slave"
customer display units 3, three remote control units 4 and a master remote control
unit 5.
[0017] The dispensing means 1 comprises a printer and processing means. On operation of
a button or the like by a customer, the printer issues a ticket. The tickets 6 issued
by the printer 1 are preferably numbered sequentially. The customer display 2 includes
a display panel 7 on which the number of the ticket currently being served is displayed.
The slave displays 3 also display the number being served. The display unit is powered
from the mains 8.
[0018] Each remote control unit includes a button 9 which a member of serving staff operates
when it is desired to update the number on the display unit 2. This will normally
be after each customer has been served. The display means 2 includes control circuiting
which prevents too rapid an advance of the numbers displayed in order that each number
will be displayed for long enough to be noticed by the customers, even if the control
units are operated twice within a short space of time. For example, once the display
has advanced once, any further advance is inhibited for, say, 30 seconds. The unit
may also include a repeater display 20 to inform the staff operator of the customer
to be served next. Thus, the display means transmits the current ticket or serving
number to the remote control units for the benefit of the operating staff. Also, to
ensure that customers are alerted when the display changes, each change may be accompanied
by an audible chime, and the display may temporarily change colour. Communication
between the remote control unit 9 and the display 2 is by a "wireless" system in the
illustrated embodiment, employing an infra-red link. Thus, each control unit includes
an infra-red transmitter and the main display means 2 a receiver. The display means
2 may also include a transmitter for transmitting an indication of the number of the
ticket currently being displayed to the dispensing means 2 which also functions as
the central processing unit.
[0019] The master control unit 5 includes three buttons 10, 11 and 12, which enable the
following action to be taken: advancing the counter on the display unit by one digit,
fast advance of display numbers on the display unit and resetting the display unit
to zero. The master control unit 5 may be battery or mains powered.
[0020] In the embodiment illustrated, the ticket dispensing means 1 is housed together with
the processing means which processes data received from one or more of the dispensing
means, the remote control units and the display unit. Thus, the processing unit collects
information from the dispensing means 1 as to the time a customer takes a ticket together
with the ticket number. The processing means also collects information as to the time
at which the display means 2 is updated in response to a signal from a remote control
unit 4. By collating and processing the data, information can be provided on, for
instance, the following: the time taken to serve customers during the day, variations
in the length of the queue, the rate at which tickets are issued and also a simple
tally of the number of customers served on each day.
