For example, information such as 〇〇he floods and earthquakes. The area code indicates an area to which the emergency information data 109 is distributed. The regional information distributor distributes the emergency information data 109, sets the content of the emergency information, that is, sets the attribute code for each of the attribute codes, and registers it in the distribution center 1. This will be described later. The urgency indicates the urgency of the emergency information data 109.

FIG. 3 shows an embodiment of the configuration of the emergency information providing device 2 on the local information distributor side of the present invention. Example of region code registration on region information distributor side FIGS. 4 and 6
This will be described in detail with reference to FIG. As an example, it is assumed that an emergency information providing device 2 of a regional information distributor that distributes information to a region X as shown in FIG. The area information distributor assumes various distribution destinations of disaster information that are expected in advance, and classifies the area X for each attribute of emergency information. Each of the divided areas is called an area.

An area is the smallest regional unit that distributes the same information. Classification methods include, for example, differences in evacuation sites, street addresses,
If it is emergency information at the time of the flood, it is classified based on the river. Area registration is done by address. For example, the area of All is, for example, ○ address 番 chome, □ address ■ chome. Thus, the area X is divided into areas. Next, the registered areas are grouped, and finally, the area division data shown in FIG. 6 is created and registered. Each of the divided areas has a tree structure shown in FIG. The registered data is written in the regional information database 205 of the emergency information providing device 2 and the regional information database 106 of the distribution center 1.

An embodiment of the processing performed by the local information distributor when a disaster occurs will be described with reference to FIG. FIG. 7 shows a simplified processing procedure. When a flood occurs in the area X, the area distributor inputs the flood as an attribute code in the input unit, and the area division data B (FIG. 5) corresponding to the attribute is output from the area information database 205 to the display unit. .
With reference to the area division data, B1 is input as an area code to be distributed. If Bl is input, Bll, B1
2. The same information will be distributed to the area B13.

Next, the contents of the emergency information to be distributed, the time to be displayed on the client side, the data type ID, and the degree of urgency are input and transmitted to the distribution center 1. The distribution center 1 calls out the area division data from the area information database 106 from the distribution source and the attribute code of the received emergency information data 109. Next, specify the area to be distributed from the area code,
Client information existing in the distribution area is called from the client database 105 and emergency information is distributed to the client terminal 110. Client terminal 110
On the side, the control unit 402 checks the data type ID of the emergency information data 109, determines the display mode on the display unit 403, and displays the emergency information.

In the case of disaster information or the like, there are cases where it is necessary to distribute information having different levels of detail depending on the distribution area even if the contents are of the same kind. For example, in the case of regional information, detailed information such as an evacuation site may be used for an area near the epicenter and simple earthquake information may be used for an area far from the epicenter. When there is a request for distribution of such a plurality of emergency information data 109, the priority of distribution to the client terminal is determined based on the size of the area range indicated by the area code of the emergency information data 109.

For example, as shown in FIG.
If there is a request for distribution of two types of emergency information data 21 and A, the two emergency information data 109 need to be distributed to the client having the area code A21. The emergency information data 109 having the area information of A21 is distributed with priority, and the emergency information data 109 having the area information A is distributed to the other client terminals 110. FIG. 9 expresses the regional structure in order to clearly show the structure of the regional division to be distributed.

The data management unit 203 stores the information of the emergency information data 109 transmitted to the distribution center, the data ID, the attribute code, the area code, the urgency, and the distribution time.
Write to B. If the emergency information data 109 having a higher degree of urgency is already being delivered to the area where the emergency information data is to be delivered, the communication is notified from the delivery center to the data management unit 203 and is displayed on the display unit 204. indicate.

Based on this information, the regional information distributor calls the previously distributed emergency information data 109 from the distribution management database 206, changes the urgency and the regional code, and determines whether to redistribute again.

FIG. 10 shows an embodiment of the configuration of the emergency information distribution control unit 103 that performs processing when the distribution center 1 receives the emergency information data 109 from the local information distributor. FIG. 1 shows one embodiment of
This will be described in detail with reference to the flowchart of FIG. The transmission / reception unit 10 transmits the emergency information data 109 transmitted from the local information distributor.
1 (S1). Next, the emergency information data 109 is passed to the data information acquisition unit 301.

Next, the process proceeds to the processing (S2) in the data information acquisition unit 301. Emergency information such as disaster information often has different transmission information depending on the distribution area, and it is necessary to simultaneously receive a plurality of pieces of emergency information data 109 as shown in FIG. 5 and classify them by area. Therefore, the data information acquisition unit 301 checks the number of the emergency information data 109 and checks whether a plurality of emergency information data have been received. When there is one emergency information data, the data information added to the emergency information data is acquired, and the data information is passed to the distribution area determination unit, and (S
Go to 5).

When there are a plurality of pieces of emergency information data, the data information acquisition section 301 acquires the data information of each piece of emergency information data as a process of (S3), and checks whether or not the distribution destination area overlaps. The overlap is, for example, a case where the emergency information data # 1 is designated as a disaster summary throughout Tokyo and the emergency information data # 2 is designated as a detailed disaster information in Shinjuku. In this case, the emergency information data #
1 is desirably distributed throughout Tokyo except for Shinjuku-ku, and emergency information data # 2 is desirably distributed to Shinjuku-ku.

When there is no overlap, the emergency information data # 1 is designated for distribution to Shibuya-ku and the emergency information data # 2 is designated for distribution to Shinjuku-ku. In the latter case, since the emergency information data and the distribution area have a one-to-one correspondence, the distribution area may be determined for each emergency information data. To determine whether or not the distribution areas overlap, the area code written in the data information is checked.

The area code has a tree structure as shown in FIG. 6 and, of the area IDs to be compared, the link is traced from the structurally lower area code to the upper level, and the higher area ID is obtained.
In this case, it is determined that the distribution areas are overlapping. For example, when comparing Al and All, Al is higher and A
12 is the lower order. Obviously, region codes at the same level do not overlap. If the distribution areas do not overlap, the data information of each emergency information data is passed to the distribution area determination unit, and the process proceeds to (S5).

When the distribution areas overlap, each data information is passed to the distribution priority determining section, and the processing of (S4) is performed as follows.
Decide which emergency information data is to be transmitted to which area with priority. At this time, a distribution source ID, an attribute code, and an area code are used. The region and the region structure indicated by the region code are checked by referring to the region information database 307 from these three IDs written in the respective emergency information data.

The area indicated by the area code is, for example, Tokyo, Shinjuku-ku, or the vicinity of 00 elementary school. What is the regional structure?
The Tokyo metropolitan area has a tree structure shown in FIG. 6, which is composed of Shinjuku Ward, Shibuya Ward, and the like. Next, the emergency information data is distributed to the designated area by the above-described method. Using the example of FIG. 9, the actual distribution destination of the emergency information data designated as the area code A is the area code All, A1
2, A22, and A23. The area code in the data information is rewritten from A to All, A12, A22, and A23, and the processing by the distribution priority determination unit ends. Pass to.

In the distribution area determination unit 303, as the processing of (S6), the distribution area is determined by participating in the area information database 307 using the distributor information, the attribute code, and the area code. The procedure for determining the distribution area by the distribution area determining unit 303 is to search the area information DB for area division data as shown in FIG. 6 from the distributor information and the attribute code, and then determine the distribution area from the area code.

In the processing of (S6), the distribution management unit 304 checks whether another emergency information data has already been distributed to the distribution area of the emergency information data determined by the distribution area determination unit 303 and is currently being displayed. In the case where the emergency information data is distributed, the distribution management unit 304 writes the distribution record in the distribution management database 308. Therefore, the distribution management unit 304 can make a determination by referring to the distribution management database 308.

When the emergency information data is already distributed to the area to be distributed, the degree of urgency in the distributed data information is checked as a process of (S7). If the urgency of the new emergency information data is higher than or the same as that of the distributed emergency information data, the process moves to the distribution client determining unit 305 to distribute the new emergency information data.

If the urgency of the new emergency information data is lower, the distribution source is notified of the data information of the emergency information data as the process of (S9). In (S8), the distribution information of the emergency information data to be distributed is written to the distribution management database 308. FIG. 12 shows an example of information written in the distribution management database 308. The contents to be written are, for example,
Distributor, data ID, attribute code, urgency, area code, and distribution time. Based on this information (S7),
The distribution management as in (S9) is performed.

In the delivery client determining unit 305, (S1
In step 0), the client terminal to be delivered is specified. The client terminal 110 existing in the distribution area is extracted from the client database 309 based on the distribution area determined in (S5). The distribution of the ordinary advertisement data to the client terminal 110 specified by the distribution unit 306 is interrupted (S11), and the distribution is passed to the emergency information data transmission / reception unit and distributed to the client terminal 110 (S12).

The distribution center knows the position information of the client terminal 110 by registering the client ID in the client DB of the distribution center. Also, PHS,
Mobile phone location information detection service to client terminal 1
10 allows the distribution center to use the client terminal 11 without registering the fixed location information in advance.
It is possible to know the position of 0.

FIG. 13 shows an apparatus configuration of the client terminal 110 as an embodiment. The control unit 402 controls the display of emergency information data and advertisement data on the display unit and records the data on the storage device 404. Information displayed on the display unit 403 is advertisement data and emergency information data. The display mode on the display unit 403 is changed based on the data ID of the emergency information data transmitted from the distribution center 1. FIG. 14 shows an example of the display mode of the emergency information data. For example, when the emergency information data is character information as shown in FIG. 14, the emergency information data is displayed in a part of the advertisement data already displayed, and the emergency information data is displayed on the entire display area of the display unit. If it is data that uses, rewrite it with advertising data. The control unit 402 reads the data type ID in the data information added to the emergency information data to identify the information expression form.

The embodiment of the client terminal of the present invention has the storage device 404, and the client I
D is stored. Client ID for distribution center 1
When transmitting the client ID, the control unit 402 reads the client ID stored in the storage device 406 and transmits and receives the client ID.
Send to The transmission / reception unit 401 receives the advertisement data and the emergency information data from the distribution center, and sends them to the control unit 402.

The client terminal 11 in the embodiment of the present invention
No. 0 has a storage device 404, in which emergency information data and advertisement data are temporarily stored in the storage device, and can be called from the control unit 402.

As the transmitting / receiving unit and the input unit, a PHS or a mobile phone can be used. As a result, the position information of the client can be easily transmitted to the distribution center.

The display unit 403 has a built-in backup battery, can perform power failure compensation, uses low power consumption, and uses thin liquid crystal. As a result, it is possible to receive and display emergency information data in a power outage state such as during a disaster.

Normally, the advertisement data from the wide area information distributor is displayed on the client terminal 110, and the terminal can be installed at no cost or at low cost based on the advertisement cost.
