[Conventional technology]

Conventionally, there has been a mobile station (taxi) device for this type of AVM system as shown in FIG. In the figure, 1 is a CPU that performs processing and creates codes, 2 is a car number setting unit that manually sets the car number, and 3 is a Sari/Impost signal receiver, which has overlapping transmission areas in each region. This system receives position information from sign posts that are distributed in a manner that prevents traffic from occurring.

Further, 4 is a memory for storing various information and procedures necessary for processing the CPUI, 5 is a counter, 6 is an antenna duplexer for sharing the antenna of the command radio and the sign post signal receiver 3; 7 is for exchanging codes between the IJit-less machine and the CPUI (7) MODEM (
Ilo, including a modem (modulator/demodulator), C0DEC (code/decoder),
8 is a radio device for communicating with a base station, and 9 is a taxi meter, which functions as an actual vehicle information indicator that outputs actual vehicle or vacant vehicle information to the CPUI.

Next, the operation will be explained. The mobile station sends the necessary data to the central (base station) as an AVM system, but
This includes information on the mobile station's dynamic state (in the air, actual vehicle), location for 2 hours, and vehicle number.

Position information is received by the sign post signal receiver 3 via the antenna and antenna duplexer 6 at the mobile station from sign posts distributed in each region, processed by the CPU, and stored in the memory 4. Obtained by memorizing. When the mobile station moves from one location to another as it travels, it receives a new signpost signal for that area, updates the memory contents, and always stores the location information from the signpost at its current location.

The operation will be explained in more detail below using FIG. 4. That is, the mobile station device interlocks with the taxi meter 9, receives information on actual vehicles and empty vehicles, and judges this (step 101).
If the vehicle is empty, as shown in FIG. 4, every time a transmission signal from a sign post is received (step 102), the position information is stored in the memory 4 of FIG. 3 (step 103), and the counter 5 is reset. and (step 104) make it count the time. In addition, when the vehicle becomes an actual vehicle, the time is not counted, and the position information is only memorized (step 109) when the sign post signal is received (step 108).

As the process described above has passed, when a request for data transmission is transmitted from the command center to the mobile station via the radio 8 (steps 106 and 110), the vehicle number (this is the time slot assigned to each mobile station in advance) If assigned, no need to send) 9
The location, whether the vehicle is empty or an actual vehicle, and the residence time within the transmission area of the sign post only in the case of an empty vehicle are sent to the control room by the radio 8 via l107 (steps 107, 11).
1).

In the control room, a central processing unit not mentioned here collects and processes this data, and when a customer requests distribution, it can display vacant vehicles in the area prioritized by residence time, etc., so it is possible to dispatch vehicles. Efficiency can be improved.

[Problem that the invention seeks to solve]

In the conventional mobile station device of the vehicle position display system, the above data was sent from the mobile station, so when there is an empty vehicle, it is possible to efficiently dispatch a vehicle, but it is difficult to dispatch the vehicle during extremely busy hours. When the actual number of taxis is high, it is difficult to find a vacant taxi, and because it is difficult to find a vacant taxi at a busy time when the most efficient taxi allocation is to be achieved, the objective cannot be achieved.

This invention was made in order to eliminate the drawbacks of the conventional ones as described above, and it is possible to send out the actual vehicle time after it becomes an actual vehicle, so that when there is no vacant vehicle, the base station can check the possibility that the vehicle will become vacant soon. It is an object of the present invention to provide a mobile station device of a vehicle position display system that can find a high-priced actual vehicle and allocate the vehicle.

[Means for solving problems]

The mobile station device of the vehicle position, etc. display system according to the present invention includes an actual vehicle time measuring means that receives a signal from an actual vehicle information indicator and measures the actual vehicle time, and a radio device that operates when a data transmission request is received from a base station. and transmission control means for transmitting actual vehicle time and position information.

[Effect]

In this invention, the actual vehicle time measuring means counts the time since the actual vehicle became a vehicle, and the position information storage means stores the position information from the sign post, and this information is stored in response to a transmission request from the base station. is transmitted to the base station.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
The figure is an overall configuration diagram showing an embodiment of a mobile station device of a vehicle position display system according to the present invention. As is clear from FIG. 1, this embodiment is provided with a sign post signal receiver 3 for receiving position information from a sign post, an actual vehicle information indicator 9 for emitting information on actual vehicles and empty vehicles, and an actual vehicle time measuring means. 52 measures the actual vehicle time after the actual vehicle information indicator 9 issues the actual vehicle information, and the position information storage means 51 measures the actual vehicle time.
The location information received by the sign post signal receiver 3 is stored, and the transmission control means 53 is configured to transmit the actual vehicle time and location information when there is a transmission request from the base station.

FIG. 2 shows a specific equipment configuration of the embodiment apparatus shown in FIG. The equipment configuration of this mobile station is similar to the conventional device shown in FIG. The processing details are the same as those shown in Figure 4 in the case of an empty vehicle, but in the case of an actual vehicle,
The content of processing by the CPU is different, and this is shown in FIG.

That is, in the case of a real vehicle, the counter 5 shown in FIG. 3 should be reset only when the vehicle becomes a real vehicle based on the information from the taximeter 9 (steps 201, 202), and the elapsed time in the real vehicle 1 is counted. Then, when the actual vehicle is running, the signal from the sign post is received (step 108), the position information is memorized (step 109), and when a signal from a new sign post is received as the vehicle is driving, the position information is updated as usual. It's the same.

With the configuration and processing method of the mobile station as described above, the information from the mobile station is the car number 1 position when the car is empty.

Information on the residence time there is sent to the base side (steps 106 and 107), and in the case of an actual vehicle, information on the car number 2 position and the time since the vehicle became an actual vehicle is sent to the base side (steps 110 and 204). . However, the car number does not need to be transmitted if a time slot has been assigned to the mobile station in advance.

Therefore, when the base receives a call from a customer requesting a ride, as a result of computer processing based on the information from the mobile station mentioned above, (1) a predetermined priority order of vacant car numbers in the area; (For example, give priority to empty cars with a long residence time within a certain period of time, etc.).

(2) If there are no vacant cars in that area, the next real car in that area will be automatically searched, and the real car that has been in use for a certain period of time (for example, the statistical average of real car time) will be automatically searched for. are displayed in order of priority starting from the longest one.

By performing the above processing on the base side, there are no vacant vehicles in the area using conventional methods, so it is possible to avoid customers, or as a second-best measure, to search for vacant vehicles in other areas far away. During busy times when the number of actual vehicles is high, it becomes possible to find and order vehicles that will soon become vacant in the area or nearby areas.

Therefore, it is possible to greatly improve the situation in which the conventional rAVM is useless because there are no empty cars at the critical time when it is needed (i.e., during busy times).

〔Effect of the invention〕

As described above, according to the mobile station device of the vehicle position display system according to the present invention, the actual vehicle time in the case of an actual vehicle is transmitted as data from the mobile station together with the position information, so that it can be used in areas where there are no vacant vehicles. This has the effect of being able to identify actual vehicles that will become vacant soon, further improving vehicle allocation efficiency.
