Abstract

PURPOSE:To switch the entrance/exit mode of an entrance/exit gate for optimum control of the flow of people near the entrance/exit gate. CONSTITUTION:The traffic information of people around a ticket barrier is read (S1). Based on the read information, respective degrees of necessity ai* and bi* of the entrance/exit mode of a ticket barrier are calculated (S2) with the help of fuzzy inference. The degrees of necessity ai and bi, which are forcasted based on an ordinary traffic pattern and set in advance, and the degrees of necessity ai* and bi* obtained from the actual traffic condition are added to calculate the final degrees of necessity ai and bi of the entrance/ exit mode (S3). A mode is decided based on the degrees of necessity ai and bi and a preset threshold Rth (S4). Based on the decision result, control output for mode switching for each ticket barrier is issued (S5). Thus, the ticket barrier can be efficiently switched for control, and congestion around the ticket barrier can be prevented.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an entry/exit mode switching control device for an entry/exit gate that switches and controls the entry/exit modes of a plurality of rows of entry/exit gates arranged at an entrance/exit for both entry and exit purposes.

0002

[Prior Art] This type of entrance/exit gate is an automatic ticket gate (automatic ticket gate) equipped with a ticket gate function (operates as an entrance gate) and a ticket collection function (operates as an exit gate), which is provided at a station ticket gate, for example. (hereinafter referred to as ticket gate), etc. Such a ticket gate has a pair of ticket gates installed parallel to each other at the ticket gate, and has an entry side and an exit side when viewed from the concourse side.
It has two pairs of doors that each rotate horizontally.
By controlling the opening/closing of the entry side door, it operates as an entrance gate to check the ticket gates for people entering from the concourse side to the platform side, and by controlling the opening/closing of the entry side door, it operates as an entry gate and operates as a gate for people entering the platform from the concourse side. Tickets are collected from the side to the concourse side, and the system is configured so that it can be switched between an entry mode and an exit mode as appropriate.

[0003] Here, the flow of people at the station ticket gate is as follows:
It varies greatly depending on the time of day and the arrival and departure status of trains. For example, regarding time of day, there are many people who come in when they go to work in the morning, and there are many people who come out when they leave work in the evening. Also, regarding the arrival and departure status of trains, when a train arrives, the number of participants increases. Furthermore, for example, if the ticket gate closer to the platform where the train arrived is in the entry mode, and the ticket gate closer to the platform where the train is about to depart is in the exit mode, the person heading to the ticket gate from the train arrival platform and the ticket gate People heading to the train departure platform through the gate cross on the entrance side (platform side) of the ticket gate, and the flow of people trying to exit the ticket gate blocks the passage of people trying to board the train. For this reason, it is necessary to appropriately switch and control the entrance/exit mode of the ticket gate depending on the time of day, train departure/arrival status, etc.

0004

[Problem to be Solved by the Invention] By the way, as mentioned above, the traffic situation of people at the ticket gate is generally determined by the time of day, the arrival and departure status of trains, etc. It is possible to envisage normal traffic patterns at For this reason, in the past, the switching of the entry/exit modes of multiple ticket gates was controlled by time or manually based on pre-assumed traffic patterns, thereby facilitating the smooth flow of people entering and exiting the ticket gates. We are trying to make this happen.

[0005] However, in cases where traffic conditions differ from the normal traffic pattern due to, for example, one of the ticket gates breaking down or the train schedule being disrupted or the departure and arrival times of trains being changed, the conventional Control methods cannot provide sufficient countermeasures. The present invention has been made in view of the above circumstances, and is an entry/exit mode switch for an entry/exit gate that enables switching control of the entry/exit mode optimal for the traffic situation even when a traffic situation different from normal occurs. The purpose is to provide a control device.

[0006]

[Means for Solving the Problems] Therefore, the present invention has the following features:
As shown in the figure, multiple rows of entrance/exit gates for both entry and exit are installed at the entrance/exit, and the entry modes of the plurality of entrance/exit gates are changed according to the traffic conditions of people on the entrance and exit sides of the entrance/exit. An entry/exit mode switching control device for an entry/exit gate that controls switching of exit modes in groups includes a traffic situation detection means for detecting the traffic conditions of people on the entrance and exit sides of the entrance/exit, and calculation means for calculating, by fuzzy inference, the degree of necessity to set each entry/exit gate to the entry mode and the degree of necessity to set it to the exit mode, respectively, based on the calculated degree of necessity to set the entry mode and the degree of necessity to set the exit mode; , based on the degree of necessity for the entrance mode and the degree of necessity for the exit mode, preset for each gate based on the normal traffic patterns of the entrance and exit sides of the entrance and exit, which are assumed from the unique characteristics of the entrance and exit. The present invention includes a mode determining means for determining the entry/exit mode of each entrance/exit gate, and a control means for controlling mode switching of each entrance/exit gate based on the determination result of the mode determining means.

[0007]

[Operation] In this configuration, the traffic situation detection means detects the traffic situation of people on the entrance side and the exit side of each entrance/exit gate installed at the ticket gate. The calculation means calculates the degree of necessity for each gate to be set to the entry mode and the degree of necessity for the gate to be set to the exit mode, respectively, based on the detected traffic conditions. The determination means is based on the degree of necessity for the entry mode and the degree of necessity for the exit mode, which are preset based on the normal traffic pattern assumed from the unique characteristics of the entrance/exit, and the calculated current traffic situation. Switching between the entry and exit modes is determined for each gate based on the degree of necessity for the entry mode and the degree of necessity for the exit mode. The control means controls mode switching of each gate based on the determination result of the determination means.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to an automatic ticket gate installed at a station ticket gate will be described below with reference to the drawings. In FIG. 2, the station ticket gates are equipped with n ticket gates serving as entry/exit gates for both entry and exit, and ticket gates G1, G2, . . . corresponding to entry/exit gates 1 to n are arranged. Gn
is configured. The ticket inspection machines 1, 2, . . . , n have the same configuration, and the ticket inspection machine 1 will be explained. Ticket gate machine 1
has a pair of ticket gate bodies 1A and 1B installed parallel to each other along the traffic direction, and is located on the concourse side (left side in the figure).
It has two pairs of doors 2 and 3 on the entrance side and the exit side, respectively, which rotate in the horizontal direction when viewed from above. Each ticket gate main body 1A,
On the top of 1B, there are ticket slots 4A and 4B for inserting tickets.
is provided, and ticket exits 5A and 5B are provided in front of the door attachment part.
is provided.

[0009] When the entry mode is set (the ticket gate operates), the person on the concourse side inserts the ticket into the ticket slot 4B of the ticket gate main body 1B, which has a ticket gate function. The door 3 on the entry side when viewed from the course side opens. In addition, when the mode is in entry mode (ticket collection operation), the person on the platform side (on the right side in the figure) inserts the ticket to the station into the ticket slot 4A of the ticket gate main body 1A that has a ticket collection function. By inserting it, the door 2 on the entrance side as seen from the concourse side opens. In addition, each ticket gate G1, G2,
..., the predetermined areas A1, A on the home side corresponding to Gn
2,..., An and the predetermined area B1 on the concourse side,
Cameras 6 and 7 serve as traffic condition detection means for detecting the traffic conditions of people in B2,..., Bn, respectively.
They are installed on the platform side and the concourse side. The cameras 6 and 7 input information regarding the number, direction of movement, and speed of passersby to the control unit 8 by processing the captured images using, for example, a CCD, which is a solid-state imaging device.

The control unit 8 has a built-in microcomputer, and controls each ticket gate 1 according to the flowchart shown in FIG. 3 based on information from both the cameras 6 and 7.
, 2,..., n, the degree of necessity of the entry mode and the degree of necessity of the exit mode are calculated by fuzzy reasoning, and based on these calculated degrees of necessity and the characteristics unique to the ticket gate, such as time of day and train departure/arrival status, etc. Assumed ticket gates G1, G2,・
..., Gn Optimum based on the degree of necessity to use the entrance mode and the degree of necessity to use the exit mode preset for each ticket gate 1, 2, ..., n according to the normal traffic pattern of the entrance side and exit side Based on the determination result, a mode switching control signal is output to the ticket gate machines 1, 2, . . . , n at the ticket gate to perform group control. Here, the control unit 8 corresponds to calculation means, determination means, and control means.

Next, the mode switching control operation of the apparatus of this embodiment will be explained based on the flowchart of FIG. First, in step 1 (indicated by S1 in the figure and the same applies hereinafter), information regarding the traffic conditions of people on the platform side and the concourse side is input from both cameras 6 and 7. The above information includes:
The number of people moving in the exit direction (towards the ticket gate) in each area Ai (i = 1 to n) on the home side XAi and their average speed VAi, the number of people moving in the opposite direction to the exit direction XB
i' and its average speed VBi', and the number of people moving in the entrance direction (ticket gate direction) in each area Bi (i = 1 to n) on the concourse side XBi and their average speed VBi, opposite to the entrance direction The number of people moving in the direction XAi' and their average speed VAi'.

In step 2, the ticket gate Gi (i=1
For the i-th ticket gate i corresponding to . In this embodiment, when calculating the degree of necessity ai*, bi* for the entry/exit mode of ticket gate i,
In addition to i, the inference is made by taking into consideration the traffic conditions at ticket gates Gi-1 and Gi+1 on both sides of i.

Using fuzzy set membership functions for the number of passersby X and their average speed V shown in FIGS. Find the degree. Here is an example of a rule. ■ if (XAi+1 is PB) and (
VAi+1 is Z) and (XBi is Z)
then bi * = 1 ■ i
f(XBi′is PB)and(VBi′is
Z) then ai *=-1 rule ■ is when there are many people heading towards the exit direction on the home side of the neighboring ticket gate Gi+1, and their speed is very slow.
If the home side of ticket gate i+1 is crowded with contestants and there are very few people heading toward the entrance direction on the concourse side of ticket gate Gi, this means that ticket gate i is set to the entry mode. Rule ■ is that many people enter the platform side of ticket gate Gi and their speed is very slow.
This means that if the platform side of is crowded with visitors, ticket gate i will be closed. Note that the above rule is an example, and there are many other rules.

[0014] Then, the minimum matching value of the antecedent part of each rule multiplied by the value of the consequent part is the necessity degree ai *
Alternatively, the matching degree value aik* or bik* (k=1 to m indicates the rule number) for each rule of bi*. Furthermore, the degree of necessity aik* or bik* calculated for each rule is added, and the total value is the degree of necessity for the entrance mode of ticket gate i based on the current traffic situation calculated from the entire rule. ai* and the degree of necessity for the participation mode is bi*.

[0015] In step 3, the degree of necessity to set the ticket gate i in the entry mode and the degree of necessity to set it in the exit mode are determined in advance based on the normal traffic pattern that can be assumed based on the time zone, train departure and arrival conditions, etc. bi ′, the degree of necessity ai * for the ticket gate i to be set in the entry mode based on the current traffic situation calculated in step 2, and the degree bi * Degree of necessity for each entry mode ai
(ai=ai'+ai*) and the participation mode necessity degree bi (bi=bi'+bi*) are calculated.

In step 4, the values ai and bi of each degree of necessity calculated in step 3 are set to a preset threshold value Rth.
The entry/exit mode switching of ticket gate i is determined by comparing with the above. For example, when ai <Rth, bi <Rth,
It is determined that the ticket gate i is stopped and the ticket gate Gi is not used. Further, when ai > bi and ai > Rth, the ticket gate i is determined to be in the entry mode. vice versa,
When ai <bi and bi >Rth, the ticket gate i is determined to be in the entry mode.

In step 5, a mode switching control signal is output to each ticket gate machine 1, 2, . . . , n based on the determination result in step 4. That is, when the ticket gate machine i is determined to be in the entry mode, the drive control is performed to check the tickets for people on the concourse side, and conversely, when the ticket gate machine i is determined to be in the exit mode,
Drive control is performed to collect tickets from people on the platform side. In this embodiment, an example of an automatic ticket gate installed in a station as an entrance/exit gate for both entry and exit is shown, but it goes without saying that the present invention can be applied to other such entrance/exit gates. .

[0018]

[Effects of the Invention] As explained above, according to the present invention, the entry/exit modes of a plurality of entry/exit gates are switched based on the traffic conditions such as the number of people near the entrance/exit and the flow of people using fuzzy reasoning. Since the structure is configured to perform control, it is possible to efficiently switch between entry and exit modes, and the flow of people at the entrance and exit can be facilitated. In addition, if applied to ticket gates at stations, for example, even if traffic conditions are different from normal due to disruptions to train schedules, it will be possible to select the optimal mode for the traffic conditions, thereby preventing congestion at ticket gates. .
