Description

Detailed Description of the Invention

[0001]

The present invention relates to, for example, an AVM system (Automatic Vehicle) for a taxi business.
e Monitoring System: automatic display system for vehicle position and the like), a display system of a map screen display device of a base station and a regional display device.

[0002]

2. Description of the Related Art An AVM system is composed of a base station and a plurality of mobile stations, and collects data such as position, dynamic information, vehicle number, etc. of each mobile station from the base station via a wireless line. The data is displayed on each display screen of the map display device and the regional display device of the base station.

FIG. 4 shows an example of the display on the map display device, and FIG. 3 shows an example of the display by region on the display device by region.
Shown in

As shown in FIG. 4, the area where the mobile station operates is divided into areas of a predetermined size in advance. FIG.
In the example shown in (1), it is equally divided into 12 districts of district numbers 1-12. In the figure, reference numerals 100 and 101 indicate the location and dynamic display of the mobile station, and it is shown that the mobile station with the vehicle number 100 exists in the area 1 and the mobile station with the vehicle number 101 exists in the area 2. Is displayed on the display screen of.

FIG. 3 is an example of an area-specific display for displaying the data of mobile stations located in each area of the area numbers 1 to 12 in a tabular format. In the figure, a indicates a display field for district names, and b indicates a display field for vehicle numbers of mobile stations.

The area division of the display screen for each area is made to coincide with the area division in the map display shown in FIG.
Based on the data such as position, movement information, and vehicle number sent from each mobile station, the vehicle number of the current position is color-coded and displayed on the map display screen of FIG. In the display column of the display screen, color-coded display according to the movement is similarly performed. For example, in an AVM system for a taxi business, in order to efficiently distribute vehicles, a mobile station in which a customer is in a real vehicle state is displayed in red, and an empty state is displayed in white. ing.

Further, the map display screen shown in FIG. 3 can be enlarged or reduced in size by switching the screen, which facilitates grasping the vehicle display on the map.

For example, FIG. 3 shows a wide area display showing the entire operating area of the mobile station. By selecting the middle area setting switch provided on the console of the base station, the map screen is enlarged at a predetermined magnification. You can switch to the middle range display. Further, by selecting the narrow area setting switch, the map screen can be switched to the narrow area display with a higher magnification. On the contrary, by switching the map screen display to the narrow area display and then selecting the middle area setting switch or the wide area setting switch, it is possible to switch the map screen to the middle area display or the wide area display reduced by a predetermined magnification.

[0009] The taxi dispatcher carries out the dispatch operation while looking at the data display of the mobile station displayed on the above-mentioned area-based display screen or map display screen.

[0010]

SUMMARY OF THE INVENTION In the above-mentioned method, when the areas for the district display screen and the map display screen are set independently, the vehicle display is erased from the area display screen when the vehicle moves. It may end up. Therefore, it is necessary to make the areas of the display screen for each area and the map display screen match.

At this time, if the districts are divided into rectangular or square shapes regardless of the road display on the map, the administrative divisions such as municipalities will be ignored, and the districts and the district-by-division display screens will be ignored. There will be a discrepancy with the name. Further, since it is irrelevant to the moving state of the vehicle, there is a possibility that vehicles running on the same road may be partially displayed in different areas.

An object of the present invention is to provide an AVM system capable of making the display screen of a base station easy to see by properly setting the settings for each district in consideration of the above points. .

[0013]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention divides districts into areas along the administrative divisions such as municipalities by performing the divisions along the road display displayed on the map display screen. By setting the minutes, the areas on the map display screen and the display screen for each area can be easily seen. In addition, the settings for each district can be set on the map display screen using a mouse or a trackball to simplify the operation.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 and 2 are views showing an example of a method of dividing a district according to the present invention. In order to divide the areas along the road on the map display screen, the same area name as the city name or the town name can be set. Further, even on curved roads, it can be set within one district, so that the vehicle display on the district display screen can be easily seen.

An embodiment of the present invention will be described below. s2
Is a display screen for each area according to the present invention, and t2 is a corresponding map screen and areas.

As indicated by t2, broken lines representing districts are set along the road on the map. The area-specific display screen corresponding to each area is designated as s2. Up to 12 districts can be set for each district.

In the setting method, the locus is displayed by dragging the pointer on the road on the map screen with a mouse or a trackball (not shown). When confirmed, set the minutes for each district by button operation.

[0018]

According to the present invention, since each district can be set along the road display on the map display screen, the regions on the map display screen and the area-specific display screen can be easily displayed. In addition, the districts that match the Kutasea vehicle dispatching business can be set up according to the administrative divisions as needed.

Further, since the actual setting operation for each district can be performed by using the mouse or the trackball, the operation of the base station can be simplified.
