[Prior art]
Conventionally, when getting on a taxi vehicle from a station, a passenger has to go to the taxi platform (station parking lot) from the station premises and search for the taxi vehicle.
[0003]
[Problems to be solved by the invention]
By the way, when there are a plurality of exits of the station, for example, the east exit and the west exit, the passenger generally uses the taxi hall at the entrance / exit closest to the destination. However, at the taxi landing at the entrance where the number of people entering and exiting is extremely small, the number of taxi vehicles waiting is small. For this reason, a situation occurs in which a person who gets on a taxi vehicle from a taxi landing at a doorway where many taxi vehicles are waiting avoids an entrance / exit where there are few taxi vehicles waiting, and reaches a destination earlier.
[0004]
Therefore, conventionally, there has been a demand for knowing the number of taxi vehicles waiting at the taxi landing in the station premises. Also, if the weather is extremely hot or extremely cold, there is also a request to wait for a taxi vehicle in a station equipped with air conditioning rather than waiting for a taxi vehicle at the taxi platform outside, for this reason, in the station premises, There is an increasing demand to know the number of taxi vehicles waiting.
[0005]
Therefore, the present invention pays attention to the above problems, and a taxi number display system capable of knowing the number of taxis waiting in a taxi hall in a station, and a taxi number counting method used in the taxi number display system. It is an issue to provide.

DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described below with reference to the drawings.
FIG. 2 is a diagram showing an embodiment of a taxi number display system that implements the taxi number counting method of the present invention. As shown in the figure, the taxi number display system is provided near the entrance of the taxi hall, and includes an entrance roadside device 200A that performs wireless communication with an onboard vehicle 100 equipped with the vehicle-mounted device 10 that passes through the entrance. An exit roadside device 200B that is provided near the exit of the landing and performs wireless communication with the mounted vehicle 100 passing through the exit, and the number of taxi vehicles that are provided in the station and are waiting at the taxi landing are displayed. And a display 300 (= display means).
[0016]
In addition, taxi vehicles and ordinary vehicles enter the taxi hall in a mixed manner. Moreover, the vehicle-mounted device 10 described above has a storage medium (not shown) that stores a vehicle ID (= vehicle identification information) for identifying the mounted vehicle 100, and the inquiry signal transmitted by the entrance and exit roadside devices 200A and 200B. In response to the reception, a response signal including the vehicle ID is transmitted.
[0017]
Furthermore, the above-mentioned inlet side device 200A, the outlet side device 200B, and the display device 300 are each connected to a microcomputer 400 (hereinafter, μCOM 400). The μCOM 400 includes a central processing unit (CPU) 401 that performs various processes in accordance with a processing program, a ROM 402 that is a read-only memory that stores a processing program and the like performed by the CPU 401, and a work that is used in various processing processes in the CPU 401. The RAM 403 is a readable / writable memory having an area, a data storage area for storing various data, and the like.
[0018]
The ROM 402 has a vehicle ID area. In this vehicle ID area, vehicle IDs of all taxi vehicles using the taxi hall (hereinafter referred to as taxi vehicle ID) are stored in advance. Then, the CPU 401 in the μCOM 400 described above counts the number of taxi vehicles waiting in the taxi hall using wireless communication performed between the entrance or exit roadside device 200A or 200B and the mounted vehicle 100. Counting processing and display processing for displaying the counted number on the display 300.
[0019]
The detailed operation of the taxi number display system described in the above outline will be described below with reference to the flowcharts of FIG. 3 and FIG. First, the CPU 401 performs an entrance process as shown in FIG. 3 at regular time intervals. In this entrance process, the CPU 401 first transmits an inquiry signal to the entrance roadside device 200A (step S1).
[0020]
If the entrance roadside device 200A does not receive a response signal in response to the transmission of the inquiry signal (N in step S2), the CPU 401 determines that there is no mounted vehicle 100 passing through the entrance roadside device 200A, and immediately returns. To do. On the other hand, if there is a mounted vehicle 100 that passes through the entrance roadside device 200A and enters the taxi hall, the mounted vehicle 100 transmits a response signal including the vehicle ID in response to receiving the question signal. To do.
[0021]
When the response signal is received by the entrance roadside device 200A (Y in step S2), the CPU 401 next transmits the vehicle ID transmitted from the mounted vehicle 100 passing through the entrance roadside device 200A among the taxi vehicle IDs. It is determined whether or not there is a match with (passing vehicle ID) (step S3). This determination makes it possible to determine whether the mounted vehicle 100 passing through the entrance roadside device 200A is a taxi vehicle or a general vehicle.
[0022]
If there is no ID that matches the passing vehicle ID among the taxi vehicle IDs (N in step S3), the CPU 401 determines that the mounted vehicle 100 passing through the entrance roadside device 200A is a general vehicle, Return immediately. On the other hand, if there is an ID that matches the passing vehicle ID among the taxi vehicle IDs (Y in step S3), it is determined that the mounted vehicle 100 passing through the entrance roadside device 200A is a taxi vehicle, and the entrance road side It is detected that the taxi vehicle has passed through the vessel 200A. As is apparent from step S3, the CPU 401 functions as an entrance passage detection unit.
[0023]
Next, the CPU 401 matches the passing vehicle ID among vehicle IDs of taxi vehicles (hereinafter referred to as standby taxi vehicle IDs) stored in a standby taxi vehicle area in the RAM 403 as storage means described later. It is determined whether or not there is (step S4). In the standby taxi vehicle area, the vehicle ID of the taxi vehicle that has once passed through the entrance roadside device 200A is stored until it passes through the exit roadside device 200B. Therefore, it is possible to determine whether or not the taxi vehicle detected in step S3 has passed through the entrance roadside device 200A more than once without passing through the exit by the determination in step S4.
[0024]
At this time, if there is an ID that matches the passing vehicle ID among the waiting taxi vehicle IDs (N in step S4), the CPU 401 determines that the taxi vehicle has passed through the entrance roadside device 200A for the first time. The number m stored in the number area in the RAM 403 is incremented (step S5).
[0025]
Thereafter, the CPU 401 functions as a counting means and performs display processing for displaying the number m on the display 300 installed in the station premises (step S6), and then uses the passing vehicle ID as a standby taxi vehicle ID as a standby taxi vehicle. Store in the area (step S7).
[0026]
On the other hand, if there is an ID that coincides with the passing vehicle ID among the waiting taxi vehicle IDs (Y in step S4), the CPU 401 determines that the passage has passed through the entrance roadside device 200A for the second time or more, and addition stop means And returns immediately without incrementing the number m described later. Therefore, even if there is a taxi vehicle that passes through the entrance twice, for example, by performing a back travel near the entrance, the second and subsequent passes of the entrance roadside device 200A are not added, and the taxi vehicle can be accurately waited. The number can be counted.
[0027]
By the above entrance processing, the number m is incremented each time the taxi vehicle passes through the entrance roadside device 200A, and the passing vehicle ID is stored in the standby taxi vehicle area as the standby taxi vehicle ID.
[0028]
Next, the CPU 401 performs an exit process as shown in FIG. 4 at regular intervals at a timing different from the entrance process. In this exit process, the CPU 401 first causes the exit roadside device 200B to transmit a question signal (step S8).
[0029]
If the exit roadside device 200B does not receive a response signal in response to the transmission of the inquiry signal (N in step S9), the CPU 401 determines that there is no mounted vehicle 100 passing through the exit roadside device 200B and immediately returns. To do. On the other hand, if there is a mounted vehicle 100 that passes the exit roadside device 200B and exits the taxi hall, the mounted vehicle 100 transmits a response signal including the vehicle ID in response to reception of the question signal.
[0030]
When the exit roadside device 200B receives this response signal (Y in step S9), the CPU 401 next transmits the vehicle ID transmitted from the mounted vehicle 100 passing through the exit roadside device 200B among the standby taxi vehicle IDs. It is determined whether or not there is a match with (passing vehicle ID) (step S10). This determination makes it possible to determine whether the mounted vehicle 100 passing through the exit roadside device 200B is a taxi vehicle or a general vehicle.
[0031]
At this time, if there is no ID that matches the passing vehicle ID among the waiting taxi vehicle IDs (N in step S10), the CPU 401 determines that the mounted vehicle 100 passing through the exit roadside device 200B is a general vehicle. Return immediately. On the other hand, if there is an ID that matches the passing vehicle ID among the waiting taxi vehicle IDs (Y in step S10), it is determined that the mounted vehicle 100 passing through the exit roadside device 200B is a taxi vehicle, and the exit It is detected that the taxi vehicle has passed through the roadside device 200B. As is apparent from step S10, the CPU 401 functions as an exit passage detection unit.
[0032]
After that, the CPU 401 functions as a counting unit, and after decrementing the number m (step S11), performs a display process for displaying the number m on the display device 300 installed in the station premises (step S12). And CPU401 erase | eliminates ID which corresponds to the said passing vehicle ID among waiting taxi vehicle ID (step S13), and returns. By the above exit process, the number m is decremented each time the taxi vehicle passes the exit roadside device 200B, and the standby taxi vehicle ID that matches the passing vehicle ID is deleted from the standby taxi vehicle area.
[0033]
As described above, the number m of taxi vehicles waiting in the taxi hall is counted using the wireless communication performed between the entrance roadside device 200A and the exit roadside device 200B and the mounted vehicle 100, If the indicator 300 that displays the counted number m is installed, it is possible to know the number of taxi vehicles waiting in the taxi hall in the station premises.
[0034]
Further, by identifying that the mounted vehicle 100 passing through the inlet or outlet roadside devices 200A and 200B is a taxi vehicle based on the passing vehicle ID obtained by the inlet or outlet roadside devices 200A and 200B from the mounted vehicle 100, the taxi Even when taxi vehicles and ordinary vehicles coexist in the hall, the number of taxi vehicles waiting can be counted reliably.
[0035]
In the above-described embodiment, in the entrance process, the mounted vehicle 100 that passes through the entrance roadside device 200A is checked by checking whether the taxi vehicle ID stored in the ROM 402 matches the passing vehicle ID. It was determined whether the vehicle is a taxi vehicle (see step S3 in FIG. 3). However, for example, if the response signal transmitted by the mounted vehicle 100 includes taxi information indicating that the vehicle is a taxi vehicle in addition to the vehicle ID, the mounted vehicle 100 is not affected by the taxi vehicle ID. It can be determined whether or not the vehicle.
[0036]
Furthermore, in the above-described embodiment, whether or not the mounted vehicle 100 passing through the exit roadside device 200B is a taxi vehicle by checking whether or not the standby taxi vehicle ID and the passing vehicle ID match in the exit process. (See step S10 in FIG. 4). However, as in the entrance process, the taxi vehicle may be identified by collating whether the taxi vehicle ID and the passing vehicle ID match.
[0037]
【The invention's effect】
As described above, according to the first and second aspects of the present invention, even if there is a taxi vehicle that passes through the entrance twice by, for example, performing back travel in the vicinity of the entrance, the addition stop means causes the second time. Since the passes are not added, a taxi display system and a taxi number counting method capable of counting the number of taxi vehicles waiting more accurately can be obtained.
