DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a map retrieval command system for retrieving a map of a location from a map database based on input location information such as an address, and outputting a command to a remote location from the retrieval result.

[0002]

2. Description of the Related Art Conventionally, for example, in a fire department, when receiving a 119 report in a communication control room, the user asks the report location, opens an atlas, confirms the report location, and then asks the situation to confirm the situation. Based on the results, a dispatch command is issued to the waiting room using the in-house broadcast. In the waiting room, when a dispatch command is received, the information is collated with an on-board atlas using a fire-fighting radio or the like, and heads to the reporting location. The above situation is shown in a flowchart.
As shown in FIG. On the other hand, devices are arranged at both the headquarters and the branch office of the fire department, and these are connected to a LAN (Local area network).
k) or a system connected to a WAN (wide area network).

[0003] Such a system is disclosed in, for example, Japanese Patent Application Laid-Open No. Hei 7-160982. FIG.
1 is a block diagram showing a configuration of a command map transmission system disclosed in the publication. In this command map transmission system,
By inputting a command such as dispatch and a map search command at the input unit 1 of the headquarters device located at the headquarters, the control unit 7 reads map data from the map database, and the determination unit 3 selects A map corresponding to the search command is determined. Then, the determined map is displayed on the display unit 4, further compressed by the data processing unit 5, and transmitted from the output unit 6 together with a command such as dispatch. The signal at this time is transmitted to a branch office via a communication network 8 such as a LAN. In the branch office apparatus, a signal from the headquarters apparatus is taken in by the input unit 9, and the map data in the signal is sent to the data processing unit 10 by the control unit 13 and decompressed. The decompressed map data is displayed on the display unit 11 together with a command such as dispatch, and printed by the printing unit 12. As described above, in the command map transmission system disclosed in Japanese Patent Laid-Open Publication No. Hei 7-160982, the map database 2 is placed only at the headquarters of the fire department, and the map retrieved from the map database 2 is transmitted to the branch office. Is displayed and printed.

[0004]

In the electronic command map transmission system described above, a map database is placed only in the headquarters device of the fire department, and the map is transmitted to the branch office every time a command is issued. However, it takes time to transmit the map from the headquarters device to the branch office device, and the transmission time hinders a reduction in the time required for emergency dispatch. In this case, even if the data to be transmitted is compressed, the larger the data, the longer it takes. By placing a map database in both the headquarters device and the branch office device, it is possible to reduce the amount of transmission between the headquarters device and the branch office device, but if the map data of the headquarters device is updated, the difference data If the data at that time is large, the transmission takes a long time, which hinders a reduction in the time required for emergency dispatch.

Accordingly, an object of the present invention is to provide a map search command system which can display and print a map at a branch office at any time in a short time according to a command from the headquarters of a fire department. .

As described above, since the map information storage means is provided in each of the command transmission device and the command reception device, when the data amount of the map of the command transmission device and the data amount of the map of the command reception device match, the capacity is large. Since it is not necessary to transmit the map data, the communication line connecting the command transmitting device and the command receiving device can be a conventional low-speed analog line.

According to a second aspect of the present invention, in the map search command system, the command receiving device includes a display unit for displaying a map and a printing unit for printing and outputting the map. When the position information and the map information amount are received, a map of the disaster area is searched from the own map information storage unit based on the received position information, and the information amount of the map obtained by this search is equal to the received map information amount. If the capacity is the same, the searched map is displayed on the display means and printed by the printing means, and when the information amount of the own map is smaller than the received map information amount, the difference map information amount at that time is predetermined. If the value is equal to or more than the value, the map retrieved from its own map information storage means is displayed on the display means and printed by the printing means. Requesting, when receiving the differential map information transmitted from the command transmitting device by this request,
Update own map information based on the received difference map information,
If the information amount of the own map is smaller than the received map information amount, and if the difference map information amount at that time is equal to or less than the predetermined value, the command transmission device is requested for the difference map information at that time. Upon receiving the difference map information transmitted from the command transmitting device, updating the own map information based on the received difference map information, displaying the updated map on the display unit, and printing the updated map on the printing unit. Features.

On the command receiving device side, when the information amount of the map from the command transmitting device does not match the information amount of its own map, the difference information amount of the map is a predetermined value (relative to the total transmission capacity). Value or the absolute value of the information capacity), and if it is equal to or more than the predetermined value, the map information is displayed on the display means and printed by the printing means. On the other hand, it requests the difference map information, and updates its own map information based on the difference map information. On the other hand, if the information amount of the difference between the map information amount of the command transmitting device and the map information amount of the command receiving device is equal to or less than a predetermined value or the difference is zero (none), the difference of the difference to the command transmitting device is determined. After requesting map information and updating its own map information based on the difference map information, the latest map information is displayed on the display means and printed by the printing means.

As described above, when the difference map information is equal to or larger than a predetermined value, the transmission of the difference map information takes a long time, so that the old map information is displayed and printed first.
Then, since the old map information is updated by requesting the map information of the difference, although the accuracy of the map is lacking for the time being, unnecessary data transmission can be prevented, so that the time required for emergency dispatch can be reduced. . When the difference map information is equal to or less than a predetermined value or is zero, the transmission of the difference map information is completed in a short time, so that the map information is displayed after updating the old map information with the difference map information first.・ Because we print
An accurate map suitable for the current situation can be obtained, and unnecessary data transmission can be prevented, so that the time required for emergency dispatch can be reduced. Therefore, according to the present invention, it is possible to display and print the map on the command receiving device side at any time in a short time.

The data capacity of the map is determined by its own data capacity analysis unit 26A.
Analyze with. Then, it is determined whether or not the data capacity of the searched map is the same as the received map data capacity. If the data size of the searched map is the same as the received map data size, the searched map is displayed in the command notification as “Disaster classification”, “Disaster location”, “Dispatch target”, “Map number”,
The information is displayed on the monitor 20 together with the “name” and “telephone number”. In this case, when displaying the map on the monitor 20, the "disaster point" is set at the center of the screen of the monitor 20. In addition, a disaster point mark is displayed at the “disaster point”. Also, a water mark is displayed based on the “water rate” of the instruction notice.

FIG. 4 shows an example of a map displayed on the monitor 20 of the command receiving device 12. As shown in FIG. As shown in this figure, the command transmission device 11 is displayed at the top of the monitor screen.
In accordance with the notification confirmation window 42 displayed on the display, the disaster classification 50, the disaster point 51, the dispatch target 52, the map number 53,
Boxes 50 to 55 for displaying each item of command notification are displayed, showing the name 54 of the caller and the telephone number 55 of the caller, and a disaster point mark indicating a "disaster point" is displayed at the center of the screen. (Flag) 56 and a water mark (circle) 57 indicating “water use” are displayed. Here the irrigation is 3
Since there are places, three water mark 57 are displayed.
In addition, as a matter of course, only the water mark 57 in the display range is displayed.

After displaying the map of the disaster area, the disaster point mark 56 and the water mark 57 on the monitor 20, the control processing section 26 prints the map on the monitor 20 based on the contents of the "disaster classification" of the instruction notice. Print at 23. in this case,
If the "disaster category" is "urgent", only one sheet is printed. The staff in the dispatch waiting room will be dispatched with this printed map.

When the control processing unit 26 determines that the data volume of the map retrieved from the map database 24 is smaller than the received map data volume, the difference at that time is a predetermined value (relative value of the total transmission capacity or information). (Absolute value of capacity) is determined. In this determination, when it is determined that the difference is equal to or greater than the predetermined value, the searched map is displayed in the command notification as “disaster category”, “disaster location”, “dispatch target”,
The information is displayed on the monitor 20 together with the "map number", "name" and "telephone number", and the map on the monitor 20 is printed by the printer 23 based on the contents of the "disaster classification" of the instruction notification. Then, after displaying and printing the map, it requests the command transmission device 11 for map data corresponding to the difference. When the difference map data is transmitted from the command transmission device 11 in response to this request, the difference map data is received and the own map data is updated.

Here, when the difference between the data capacity of the searched map and the received map data capacity is equal to or larger than a predetermined value,
The searched map, that is, the old map is displayed on the monitor 20 and is further printed by the printer 23 because if the difference map data is transmitted from the command transmitting device 11, it takes time to transmit the data, which affects emergency dispatch. . Therefore, when the difference map data is equal to or more than a predetermined value, the searched map, that is, the old map is used, and after displaying and printing the map, the difference map data is requested to the command transmission device 11 and the old map is used. Update the map data and use it at the next emergency dispatch.

On the other hand, if the difference between the data size of the searched map and the received map data size is equal to or smaller than a predetermined value, the control processing unit 26 requests the command transmission device 11 for the difference map data. When the difference map data is transmitted from the command transmission device 11 in response to this request, the difference map data is received, and its own map data is updated based on the difference map data.
Then, after updating its own map data, the latest map is displayed on the monitor 20 together with the "disaster classification", "disaster point", "dispatch target", "map number", "name" and "telephone number" of the command notification. Display and furthermore, "disaster classification" of command notice
The map on the monitor 20 is printed by the printer 23 on the basis of the contents of.

Here, if the difference between the map data capacity of the searched map and the received map data capacity is equal to or less than a predetermined value, even if the command transmission device 11 requests the difference map data, the data transmission is performed in a short time. It does not affect emergency dispatch. Therefore, when the difference map data is equal to or smaller than a predetermined value, the difference map data is requested to the command transmitting device 11, and based on the request, the old map data is updated and the latest map is displayed and printed. After transmitting the position information and the map data capacity as described above, the command transmitting device 11 transmits the difference map data if requested from the command receiving device 12. The map data of the difference is a coordinate axis when the map search command system 10 uses the vector system for displaying the map, and becomes a bitmap file when the raster system is used. The objects of the map data of the difference are mainly a newly-installed fire hydrant and fire prevention water tank, a newly constructed building and a demolished building, and the like.

Next, the processing flow of the command transmitting device 11 and the command receiving device 12 will be described with reference to the flowchart of FIG. Upon receiving the 119th report in the communication command room, the staff member of the communication command room grasps the disaster location from the information from the reporter and searches for the address in the command transmission device 11 (step S1). Then, the user inputs using the keyboard 14 and the mouse 15 to each item of the notification confirmation window 42 displayed on the monitor 13 of the command transmission device 11,

Then, upon receiving the command transmitted from the command transmitting device 11, a map of the disaster location is searched from the map database 24 based on the "map number". Then, the contents of the searched data amount of the map and the contents of the map data transmitted from the command transmitting device 11 are checked, and the update status of the searched map is checked (step S3). If the data amounts of the two maps are different, the difference data amount is analyzed (step S4). Next, it is determined whether or not the analyzed data amount of the difference is equal to or more than a predetermined value (step S5). When it is determined that the data amount of the difference is equal to or more than the predetermined value, the searched map, that is, the old map is displayed on the monitor 20. And printer 2
Printing is performed in step 3 (step S6). After displaying and printing the old map, it requests difference map data from the command transmitting device 11 (step S7). The command device 11 is
Upon receiving the request from the command receiving device 12, the request is confirmed (step S8), and then the difference map data is transmitted to the command receiving device 12 (step S9). When receiving the difference map data transmitted from the command transmission device 11, the command receiving device 12 updates its own map data based on the difference map data (step S10).

On the other hand, if it is determined in step S5 that the analyzed data amount of the difference is equal to or smaller than a predetermined value or is zero (none), a request is made to the command transmission device 11 for difference map data (step S11). When receiving the request from the command receiving device 12, the command device 11 confirms the request (Step S8), and then transmits the difference map data to the command receiving device 12 (Step S9). When receiving the difference map data transmitted from the command transmission device 11, the command receiving device 12 updates its own map data based on the difference map data (step S12). Then, the updated map is displayed on the monitor 20 and printed by the printer 23 (step S13).

As described above, in this embodiment, the command transmitting device 11 and the command receiving device 12 are provided with the map databases 16 and 24, respectively, and the command transmitting device 11 sends the command receiving device 12 the position of the disaster area. Specify the map of the disaster area by sending the information. If the data amount of the map of the command transmitting device 11 does not match the data amount of the map of the command receiving device 11, the command receiving device 12 has its own data amount. After the map data is displayed on the monitor 20 and printed by the printer 23, the map data of the difference is requested to the command transmitting device 11, and the old map data of the own device is updated based on the map data of the difference. On the other hand, if the data amount of the difference between the map data amount of the command transmitting device 11 and the map data amount of the command receiving device 12 is equal to or smaller than a predetermined value or zero, the command transmitting device 11
