DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an AVM system in which the position of a mobile station is specified and transmitted / notified to a base station.
(Automatic Vehicle Monitoring Sistem), which relates to a method for managing the position of a mobile station.

[0002] Conventional AVM systems generally include an automatic system such as a distributed transmission system or a distributed reception system, and a semi-automatic system based on manual registration by an operator. However, in these AVM systems, the mobile station itself does not have a function of specifying its own location.

On the other hand, an AVM system in which a mobile station itself can specify its own position is in the spotlight. In other words, self-contained navigation systems using dead reckoning navigation and GPS (Global Positi
This is an AVM system in which the mobile station itself specifies its own position using an oning system, and transmits its coordinate data to the base station. Incidentally, as a good example in which the position of the moving body can be specified by the moving body itself, a navigation device can be exemplified.

That is, in the latter AVM system, the base station manages the coordinate data transmitted by the mobile station in the base station, so that the base station can monitor and manage the operation state of the mobile station in close examination. it can.

[0005] Therefore, there is a need for an AVM system that can efficiently manage the location of a mobile station in its operation by utilizing such advantages. For example, in a taxi business, a luggage transportation business, and the like, a system for efficiently distributing vehicles is provided.

[0006]

[Prior art]

(1) AVM System for Identifying Current Position on Mobile Station Side FIG. 4 is an AVM system for specifying the navigation position of the mobile station by the mobile station itself, and is a block diagram showing a configuration example thereof. Although a plurality of mobile stations 1 are generally present, one mobile station 1 is represented in FIG.

[0007] 1) Configuration and operation of mobile station [0007] As a method of specifying the position of a mobile body such as a vehicle, there are a self-contained navigation system by dead reckoning navigation and a navigation assistance system such as GPS.

That is, the self-contained navigation system is a method in which the moving speed and the moving direction of the moving object are integrated with the elapsed time with the origin position as the starting position, and the position at the time is obtained. In addition, the navigation assistance system is a method of obtaining the position using radio waves emitted from a plurality of wireless stations.

In FIG. 4, a location processing device 3 of the mobile station 1 is a device for obtaining the position of the mobile station 1 as coordinate data. Incidentally, the coordinate data is, for example, coordinates represented by latitude and longitude, and is an XY coordinate system that is predetermined and promised on a map. The location processing device 3 in FIG. 4 is a device that uses both the self-contained navigation system and GPS.

That is, based on the traveling speed V _S obtained from the wheel speed sensor of the vehicle, the traveling direction D _{S of the} vehicle obtained from the terrestrial magnetism sensor, and the timer (clock) incorporated therein, the origin position is determined as the starting position, This is an apparatus that uses a self-contained navigation system for obtaining a position at a location and a system for obtaining a position using radio waves received by a GPS receiving antenna 12. However, a system using only one of them may be used.

The coordinate data obtained by the location processing device 3 as described above is transmitted to the communication interface 4
Is transmitted to the base station 2 by the wireless device 5 via the wireless LAN.

The transmission timing of the coordinate data to the base station 2 includes a polling transmission from the base station 2,
There are transmission at predetermined time intervals, transmission at predetermined movement distance intervals, and the like.

2) Configuration of Base Station The base station 2 is provided with a radio 6 for receiving the coordinate data transmitted by the mobile station 1, and converts the coordinate data received via the communication interface 7 into an AVM data processing device. Enter 8

[0014] The moving position of the mobile station 1 is displayed on the display device 10 from the coordinate data representing the position of the mobile station 1. The database 9 is a storage device for storing map data, coordinate data of the map, and the like, and the keyboard 11 is an input device for giving instructions to the AVM data processing device 8 and thus the AVM system.

3) Operation of base station FIG. 5 is a diagram for explaining a conventional mobile station management method. FIG. 5 (a) is a model diagram for explaining a mobile station management area on a map, and FIG. 5 (b) is a conceptual diagram of a database. ,.

That is, map data in a wireless service area capable of managing the position of the mobile station and coordinate data of the map are created in advance, and the map data file 13 of the database 9 is created.
It is stored in. In addition, the mobile station, that is, a taxi or a luggage transportation vehicle, preliminarily prepares area allocation data for dividing and managing an area (area A, area B, area C,...) In charge of customer service, and prepares an area allocation data file 14. It is stored in.

That is, the map illustrated in FIG. 5 (a) and the coordinate data at each point of the map are stored in the map data file 13. , District C,... Are stored in the district allocation data file 14.

Therefore, the AVM data processing device 8 shown in FIG. 4 can access the map data file 13 to display the map on the display device 10 and, based on the received coordinate data of the mobile station 1. , The position can be superimposed and displayed on the display map.

A district allocation data file 14 is searched based on the coordinate data of the mobile station 1 to determine which district (district A, district B, district C,...) The coordinate data belongs to. You can ask.

Therefore, if the positions of all the mobile stations are monitored and individually managed for each area (area A, area B, area C,...) And displayed on the display device 10, the vehicle from the customer can be obtained. When the dispatch request is issued, it is possible to provide a prompt dispatch service for each district.

[0021]

However, problems still exist in such a convenient AVM system.

That is, since the prior art has focused on easy creation of district allocation data, as shown in FIG. 5 (a), it is divided into squares having a certain distance in the east-west-south-north direction and managed. Areas are set and mobile stations, that is, vehicles are managed. In other words, the configuration is such that the actual terrain, streets, roads, railways, rivers, and other conditions are completely ignored.

For this reason, there are cases where quick dispatch service cannot be provided to customers.

For example, a vehicle located in the district B has the south exit 18 and the north exit 17 of the station 16 as a dispatching service area. You need to make a detour.

The same applies to the district A and the district D. In the district A, the area across the railroad 15 through the railroad crossing 19 must be set as a dispatching service area. The area across the river 20 must be the dispatch service area.

The technical problem of the present invention is to provide an AVM capable of providing a quick dispatch service to a customer and reducing a burden on a vehicle driver by establishing a management method capable of efficiently dispatching a vehicle. It is to realize a system.

[0027]

FIG. 1 is a diagram for explaining the basic principle of the present invention. FIG. 1A is a block diagram for explaining the configuration.
(b) is a figure which shows the example of division of a management area. Although a plurality of mobile stations are generally present, one mobile station 1a is represented in FIG.

The present invention is a mobile station management method in which a management area is determined in consideration of a mobile station 1a, that is, a traveling route of a vehicle. The AVM system targeted by the present invention is a system having the following configuration.

That is, the mobile station 1a has its own location computing device 23 for specifying its own position as coordinate data,
A radio 5a capable of transmitting the coordinate data to the base station 2a.

On the other hand, the base station 2a includes a radio 6a capable of receiving the coordinate data transmitted by the mobile station 1a, a map data file 13a in which a map is converted into data, and a predetermined management area in which the map is determined in advance. (District a, District b, District c, ...
.) A district allocation data file 14a storing data to be divided for each is provided, and the data files 13a and 14a are searched based on the received coordinate data of the mobile station 1a, and the mobile station 1a is located. And a position management system 24 for determining a management area (district a, district b, district c,...) To be managed.

Then, in the AVM system having such a configuration, the management of the mobile station is performed as follows.

That is, the management area (district a, district b,
(District c, ...)) is divided and determined along the terrain on road traffic, and a district allocation data file 14a is created.
Is a method of managing the position of the area by the district allocation data.

The terrain on road traffic refers to the terrain on which vehicles can pass. That is, the terrain is along the road laying direction.

[0034]

According to the mobile station management method in the AVM system of the present invention, the operation state of the mobile station 1a can be divided and divided according to the terrain on road traffic. That is, basically, along the road, the management area (District a, District b,
District c, ...) is determined and its management area (District a, District
(b, district c,...) The operation of the mobile station 1a can be managed by grouping each group.

Therefore, even if the straight-line distance on the map is short, there is no case where an area that is detoured on the road traffic terrain is divided and divided as the same management area. The terrain on road traffic includes road traffic regulations such as one-way traffic.

Therefore, it is possible to provide a dispatch service without delay in response to a dispatch request from a customer.

[0037]

Next, a practical example of how the mobile station management method according to the present invention can be embodied will be described with reference to examples.

(1) Configuration The AVM system to which the present embodiment is applied, that is, the navigation position self-determining AVM system in which the mobile station itself specifies its position, has the same configuration as the AVM system illustrated in FIG. The only difference is the configuration of the district allocation data file 14 (FIG. 5) stored in the database 9.

FIG. 2 is a diagram for explaining the embodiment, and is a diagram for explaining an example of district allocation. Note that the map data in the figure is the same as the map data illustrated in FIG.

That is, the area on the north side of the railway 15 is defined as the area Aa, the area between the railway 15 and the river 20 is the area Ba, and the area on the south side of the river 20 is divided and managed as the area Ca. Configuration.

That is, the railway 15, the river 20, the railroad crossing 19, the bridge 21,
In this configuration, obstacles that cause an increase in dispatch time and a decrease in dispatch efficiency of a mobile station, that is, a vehicle, such as a bridge 22, are eliminated.

(2) Operation FIGS. 3A and 3B are diagrams for explaining the operation of the embodiment. FIG. 3A is a flowchart illustrating the management procedure, and FIG. 3B is an example of a chart managed and displayed for each district. .

That is, when the base station 2 receives the coordinate data of the mobile station 1, that is, the location data in step S101, the position of the mobile station 1 is superimposed and displayed on the map (FIG. 2) in step S102.

Subsequently, in step S103, the district allocation data file of the database is searched to determine the district (area Aa, district Ba, district Ca) where the mobile station 1 is located. And it expresses in step S104.

FIG. 3B is an example of the expression, in which the numbers (102, 122, 135, 127, 105,...) Of the mobile stations are displayed in a one-column table format for each area.

Therefore, when a customer's dispatch request is issued from the corresponding area, an instruction may be given to the customer to dispatch the vehicle having the mobile station number indicated in the corresponding field to the customer. It should be noted that in this vehicle allocation, there is no detouring or detouring that may hinder vehicle allocation.

By the way, when the mobile station number is displayed,
By displaying the mobile station in the order registered in the relevant area (area Aa, area Ba, area Ca) and giving a dispatch instruction in that order, it is possible to manage the dispatch waiting time in the mobile station fairly. .

[0048]

As described above, according to the mobile station management method of the present invention, the allocation of mobile stations, that is, vehicles, can be performed without waste.

Therefore, the AVM which can provide a quick dispatch service to the customer and reduce the burden on the vehicle driver
The system can be realized.
