At this time, on the vehicle position / video display device 22, a symbol representing the position of the vehicle is displayed in different colors according to the vehicle state together with the map. FIG. 6 shows a map display example.

The cycle of transmission to the centralized center is a short cycle from the pressing of "mobilization" by the status input button of the vehicle status input device 12a to the pressing of "standby" which ends the disaster activity, and other disasters. When there is no activity, it is automatically set to a long cycle.

When it is necessary to grasp the position of the vehicle at a centralized center during patrols, movements between fire stations, etc. at times other than disaster activities, press the short cycle setting button of the vehicle state input device 12a. Correspond.

With this system, all vehicle positions and vehicle states under the jurisdiction can be completely unified, and the site of the disaster can be specified by the incoming call of No. 119, and the information of the work target is also grasped. Therefore, in the centralized center, in the event of a disaster, it is possible to direct a vehicle at the shortest point that can be dispatched to the site.
This is especially useful when multiple disasters occur at the same time.

The vehicle position / image display device 22 displays the current position of the vehicle on which the on-site conductor is on board when the vehicle is heading to the site. At this time, when switching to the map of the disaster site, the work instruction device 61 is used.

(3) Site If support information such as a building drawing is required at the site where a disaster activity is performed, the centralized center searches for the necessary information and outputs it to the FAX printer 13b wirelessly. This is possible even on the way to the scene. Various information near the site is displayed on the map of the centralized center. Detailed support information is displayed on the screen by clicking the symbol on the map on the screen. An example of support information display is shown in FIG.
The support information includes the following, which can be used to instruct the site by wireless communication or to send necessary related information to the FAX printer 13

・ Fire hydrant and water usage information ・ Notification information for dangerous materials, etc. ・ Road information such as road construction, one-way traffic, road width, etc. ・ Floor level and height of building ・ Information for vulnerable people such as elderly people living alone on the map in FIG. If you click the IJ department store at the fire site indicated by the arrow, the display will change to the one shown in Fig. 7 (1) and the building name, fire extinguishing equipment, etc. will be displayed as text information. Further, when a drawing of the building is required, clicking the drawing reference as an arrow displays the drawing of the building as shown in FIG. 7 (2). If necessary, click FAX transmission and the FA of the vehicle
It is also possible to send these support information to X.

These pieces of information are necessary for the site, but traffic information and information such as the number of floors of the building affect the formation of dispatched vehicles (whether a ladder car is dispatched, the route to the site), so the disaster location When it becomes clear, it will be added to the factors for selecting dispatched vehicles.

As the situation at the site can be understood by the centralized center,
Information such as a video of a video camera and a handwritten memo is read by the video input device 12b and transmitted. At the centralized center, it is displayed on the vehicle position / video display device 22. The work instruction device 61 is used to switch the display between the image and the map.

[Other Embodiments] As an embodiment having an effect of displaying wide area information, in the case of a disaster emergency activity support system, it is possible to grasp the arrangement of all vehicles in the case of deploying vehicles over a wide area such as a forest fire or flood damage. It is especially useful for conducting command orders. Further, although the disaster relief activity support system adopted in this embodiment does not normally have a task of patrol at all times,
As another example, in the police, security patrol cars, etc. shown in the field of industrial use, there are many vehicles that are constantly moving by patrol, and the fact that the headquarters can accurately grasp the position of the entire vehicle It is indispensable for command and order such as vehicle allocation.

In the example of the map display, the vehicles are simply displayed by symbols, but naturally it is also possible to display each vehicle individually or to display the traveling direction of the moving vehicle. Although the position measurement uses the GPS as an example, any method such as a geomagnetic sensor or a gyro may be used.
