In FIG. 2, the user information database 111 includes items such as "user ID", "destination", "location information", "safety information", and "attribute information". The "user ID" is information for identifying a user such as an employee. The "destination" is information to which a safety confirmation e-mail or message is sent. The "user ID" and the "destination" may be shared. The "position information" is position information such as latitude and longitude received from the user's terminal device 3. It is desirable to accompany a time stamp so that it is possible to refer to the received position information later. The "safety information" is the content of the reply from the user to the safety confirmation, and includes, for example, "safety", "injury (movable)", "injury (immovable)" and the like. "Attribute information" is information such as a user's name, gender, age, and affiliation.

The facility information database 112 includes items such as "facility ID", "location information", "seismic resistance", and "attribute information". The "facility ID" is information for identifying facilities such as buildings and areas where employees and the like may be located. "Position information" is information that defines the position range of the facility, and is defined by the coordinates of the corner points of the plan shape of the facility, as well as the coordinates of the center and the radius. "Earthquake resistance" is a value indicating the resistance of a facility in the event of a disaster accompanied by an earthquake, and is set in advance based on the age of the facility, the seismic standard value set in the building standard, and the like. Here, the highest seismic resistance value is "10" and the lowest seismic resistance value is "1". Seismic resistance "10" corresponds to robustness that can withstand large-scale earthquakes (seismic intensity 6 to 7), and seismic resistance "1" corresponds to cases where there is a risk of total destruction in a large-scale earthquake. "Attribute information" is information such as a facility name.

Returning to FIG. 1, the setting information 113 holds parameters such as an unsafe threshold value and a maximum distance (radius) used in processing. The unsafe threshold is a threshold for determining whether or not the response is unsafe based on the unsafe ratio (the ratio of the replies indicating unsafeness to the total number of replies for each facility located) in the reply to the safety confirmation. As the non-safety threshold value, for example, a value such as "20%" or "25%" is set. The maximum distance (radius) is the maximum value when the estimated influence range is set around the facility determined to be unsafe. As the maximum distance (radius), a value such as "1 km" is set.

The reply may be sent by e-mail or message, or may be sent via writing on a dedicated website or the like.

When a predetermined number of replies are collected, the aggregation / unsafe ratio calculation / judgment unit 104 aggregates the contents of the replies from the user information database 111, calculates the unsafe ratio for each facility, and determines whether or not it is unsafe. However, it has the function of allocating each facility to either safe, unsafe, or unconfirmed. The estimated damage degree calculation unit 105 has a function of calculating the estimated damage degree for the facility determined to be unsafe. The estimated impact range determination unit 106 assumes the estimated impact range of the radius corresponding to the estimated damage degree on the virtual security map centering on the facility determined to be unsafe, and it is unconfirmed whether it is safe or unsafe. It has a function to determine whether the facility is affected. Here, for example, it is assumed that an unidentified facility exists within the estimated influence range and is affected when the seismic resistance is lower than that of the central facility.

The non-safety ratio calculation / judgment unit 108 has a function of calculating the non-safety ratio from the calculated estimated damage degree for an unconfirmed facility and determining whether it is safe or unsafe depending on whether or not it exceeds the non-safety threshold. ing. The result output unit 109 has a function of outputting the returned safety information and information such as the status of each facility (safety, unsafety, unconfirmed, etc.) to the administrator. In addition, the total / unsafe ratio calculation / judgment unit 104 to the non-safe ratio calculation / judgment unit 108 have a function of reprocessing from the total / unsafe ratio calculation / judgment when more replies are collected due to the passage of time. have. When reprocessing is performed, the learning / supplementing unit 110 compares the current result with the previous result, and if there is a discrepancy in the determination result, adjusts the setting information 113 and adjusts the result. It has a function to make corrections.

On the other hand, the terminal device 3 possessed by the user includes a position information transmitting unit 31 and a reply transmitting unit 32. The position information transmission unit 31 has a function of periodically transmitting the position information of the terminal device 3 acquired by GPS (Global Positioning System) or the like to the safety confirmation device 1. When the reply transmission unit 32 receives a safety confirmation email or message from the safety confirmation device 1, it has a function of transmitting a reply to the safety confirmation device 1 via the email or message or writing on the website. ..

<Operation>
FIG. 5 is a sequence diagram showing a processing example of the above embodiment. In FIG. 5, the position information transmission unit 31 of the terminal device 3 periodically acquires the position information of the terminal device 3 (step S101), and transmits the acquired position information together with the user ID to the safety confirmation device 1 (step S102). ). When the position information receiving unit 101 of the safety confirmation device 1 receives the position information accompanied by the user ID from the terminal device 3, it registers it in the user information database 111 (step S103). That is, the received location information is registered in the location information column corresponding to the corresponding user ID. It is desirable to register with a time stamp indicating the date and time of reception.

After that, when the safety confirmation transmission unit 102 of the safety confirmation device 1 receives the notification of the occurrence of a disaster from the Japan Meteorological Agency or the like (step S104), the safety confirmation transmission unit 102 sends an e-mail or a message requesting the safety confirmation to the user registered in the user information database 111. Transmit (step S105). Upon receiving this, the reply transmission unit 32 of the safety confirmation device 1 inputs a reply from the user (step S106), and includes the user ID and the safety information in the safety confirmation device 1 via an e-mail, a message, or writing to a website. Send a reply (step S107). In order to facilitate the reply in the event of a disaster, it is desirable that the safety information can be input from options such as "safe", "injured (movable)", and "injured (immovable)".

When the reply receiving unit 103 of the safety confirmation device 1 receives the reply from the terminal device 3, the reply receiving unit 103 registers the safety information included in the reply in the user information database 111 (step S108). That is, the safety information included in the reply is registered in the safety information column corresponding to the corresponding user ID.

After that, the aggregation / unsafe ratio calculation / judgment unit 104 aggregates the reply contents from the user information database 111 when a predetermined number of replies are collected, calculates the unsafe ratio for each facility, and determines whether or not it is unsafe. Judgment is made, and each facility is assigned to one of safe, unsafe, and unconfirmed (step S109). FIG. 6 is a diagram showing an example of processing of aggregation / non-safety ratio calculation / determination by the determination unit 104. First, the aggregation / non-safety ratio calculation / determination unit 104 compares the position information of each record in the user information database 111 with the position information (position range) of each facility in the facility information database 112 to determine the location of each user. Specify the facility ID of the facility to be used. That is, when the latest position information of the user is included in the position information (position range) of the facility, the user is assumed to be located in the facility. The comparison of the location information may be performed in consideration of a slight error, or the location information of the facility information database 112 may be set in consideration of the error in advance.

Next, the aggregation / non-safety ratio calculation / determination unit 104 aggregates the safety information for each facility ID, and indicates safety (for example, "safe") and non-safety (for example, "injury (movable))". "Injury (immobility)") is counted, and the unsafe ratio is calculated by the ratio of the unsafe number to the total of both. Then, the aggregation / non-safety ratio calculation / determination unit 104 determines that the calculated non-safety ratio does not exceed the non-safety threshold value of the setting information 113, and determines that it is unsafe if it exceeds it. It is predetermined whether it is determined to be safe or unsafe when the unsafe ratio is equal to the unsafe threshold. Facilities that are not judged as either because there are no or few replies are considered unconfirmed.

Returning to FIG. 5, the estimated damage degree calculation unit 105 then calculates the estimated damage degree for the facility determined to be unsafe (step S110). FIG. 7 is a diagram showing an example of the relationship between the non-safety ratio and seismic resistance and the estimated damage degree. The horizontal axis shows the non-safety ratio, the vertical axis shows the seismic resistance, and the dashed line sloping to the lower right shows the relationship between the non-safety ratio and the seismic resistance, where the estimated damage level is constant. It gets higher as you go toward. Although the portion where the estimated damage degree is constant is shown by a straight line, it may be represented by a curve. That is, the higher the non-safety ratio, the higher the estimated damage level, and the higher the seismic resistance, the higher the estimated damage level if the non-safety rate is the same (if the non-safety rate is high in a facility with high seismic resistance, the damage level is considerably large). , The estimated damage level increases along the two axes of non-safety ratio and seismic resistance. In addition, the region where the unsafe ratio is larger than the unsafe threshold is regarded as unsafe. The estimated damage rate is expressed by a function f of unsafety ratio and seismic resistance (non-safety ratio, seismic resistance), and the estimated damage degree can be obtained by substituting the non-safety ratio and seismic resistance into the function f.

Returning to FIG. 5, the estimated influence range determination unit 106 then sets the radius corresponding to the estimated damage degree on the virtual security map centering on the facility determined to be unsafe (each facility in the case of a plurality of facilities). Assuming an estimated range of influence, it is determined whether or not a facility whose safety or unsafeness has not been confirmed is affected (step S111). The radius of the estimated influence range is obtained based on the non-safety ratio from the maximum distance of the setting information 113 (the radius when the non-safety ratio is 100%) (for example, if the non-safety ratio is 50%, half of the maximum distance is the radius). ). FIG. 8 is a diagram showing an example of the estimated influence range determination, in which facilities A, D, F, H, and I determined to be unsafe exist within the target range of the virtual security map SM, and each of them is defined. The estimated influence range of the radius corresponding to the estimated damage degree is drawn in the center. In addition, facilities B, C, E, G, and J are unconfirmed facilities. The numbers in the circles indicating the facilities indicate earthquake resistance.

Whether or not it will be affected shall be determined, for example, if an unidentified facility exists within the estimated impact range and is less seismic than the central facility. In FIG. 8, facilities B and C are included in the estimated influence range of facility A, and both are judged to be affected because they have lower seismic resistance than the central facility A. Further, although the facility E is included in the estimated influence range of the facility D, it is determined that the facility E is not affected because the seismic resistance is higher than that of the central facility D. Facility G is included in the estimated influence range of both facilities F and H, but it is judged that it is not affected because it has higher or equivalent seismic resistance than the central facilities F and H. Since facility J is not included in any of the estimated impact ranges, it is determined that it is not affected. Facilities that are determined not to be affected by any estimated range of impact are tentatively determined to be safe.

The above estimated range of influence is determined by the non-safety ratio and the estimated damage level obtained from seismic resistance, but if the damaged state of the facility is known, the non-safety ratio of the facility is adjusted (set) accordingly. ) May be done. As a result, when the facility is severely damaged (for example, in the case of total destruction), the estimated range of influence is increased, the range of influence on the unconfirmed facility is expanded, and the judgment is made more realistically.

In addition, the example judgment "affected when an unidentified facility exists within the estimated impact range and the seismic resistance is smaller than that of the central facility" has the advantage of narrowing down the subsequent processing targets. On the other hand, there is a possibility of leaking unidentified facilities that actually affect them. For example, when receiving information that the central facility has an earthquake resistance of "5" and that facility is in a completely destroyed state, and estimating damage to surrounding facilities based on that information, the surrounding earthquake resistance "5" If there is a facility of "7", there is a possibility that the facility of seismic resistance "7" will also be affected by partial destruction. Therefore, if it is desired that a wide range of unconfirmed facilities be targeted, all unconfirmed facilities will be affected by omitting the process of determining whether or not the unconfirmed facilities will be affected (step S111 in FIG. 5). It may be said that there is a possibility of receiving. In addition, only "whether an unconfirmed facility exists within the estimated influence range" may be determined, and the magnitude of seismic resistance may not be determined.

Returning to FIG. 5, the estimated damage degree calculation unit 107 then calculates the estimated damage degree for the unconfirmed facility determined to be affected, considering the seismic resistance of the facility and the distance from the central facility. (Step S112). FIG. 9 is a diagram showing an example of obtaining the estimated damage degree, and is an example of calculating the estimated damage degree for facilities B and C existing within the estimated influence range of the facility A in FIG. In FIG. 8, the vertical axis is the distance from the central facility and the horizontal axis is the estimated damage degree. The smaller the distance (closer to the central facility), the higher the estimated damage degree, and the larger the distance (farther from the central facility). ) Indicates that the estimated damage level is lower. Since facility A has the maximum seismic resistance of "10", the maximum value of the distance from the central facility is the maximum affected distance, and the part where the distance is zero is the estimated damage level of the central facility A. ing. The estimated damage level is calculated from the distances of facilities B and C from the central facility. In terms of implementation, the estimated damage degree can be obtained by applying the distances of facilities B and C from the central facility to the mathematical formula expressing the relationship shown in FIG. In addition, FIG. 10 conceptually shows how the estimated damage level is obtained from a diagram showing the relationship between the seismic resistance of the facility and the non-safety ratio. For example, if the non-safety ratio of facility A is 100%, the estimated damage level is the distance from facility A to facilities B and C from the points of seismic resistance: 10 and unsafe ratio: 100% in the upper right. The lowered value is the estimated damage level of facilities B and C.

Returning to FIG. 5, the non-safety ratio calculation / judgment unit 108 then calculates the non-safety ratio from the calculated estimated damage degree for the unconfirmed facility, and whether it is safe or unsafe depending on whether or not it exceeds the non-safety threshold. Is determined (step S113). FIG. 11 is a diagram showing an example of obtaining the non-safety ratio, and conceptually shows how the non-safety ratio is obtained from the estimated damage degrees of facilities B and C obtained in FIG. 10. That is, for facility B, the estimated damage degree is obtained from the position extending downward from the intersection of the line where the estimated damage degree is constant and the seismic resistance: 1 of facility B. Since this facility B exceeds the non-safety threshold, it is determined to be unsafe. For facility C, the estimated damage level is calculated from the position extending downward from the intersection of the line where the estimated damage level is constant and the seismic resistance of facility C: 5. This facility B is judged to be safe because it is smaller than the non-safety threshold. In terms of implementation, the estimated damage level is calculated by a mathematical formula that expresses the relationship between the non-safety ratio, seismic resistance, and the estimated damage level.

Returning to FIG. 5, the result output unit 109 then outputs the returned safety information and the state (safety, unsafe, unconfirmed, etc.) of each facility to the administrator (step S114). The output format may be one in which the result screen is displayed on the monitor of the safety confirmation device 1, or one in which an e-mail containing the result is sent to the administrator.

After that, when more replies are collected from the terminal device 3 due to the passage of time, the aggregation / non-safety ratio calculation / determination unit 104 to the non-safety ratio calculation / determination unit 108 aggregate / non-safety ratio calculation / determination (step S109). Reprocessing is performed from the same content as above (step S115). Then, the learning / supplementing unit 110 compares the current result with the previous result, and if there is a discrepancy in the determination result, adjusts the setting information 113 and corrects the result (step S116). ), And output the result (step S117). For example, if an unconfirmed facility that has been determined to be unsafe is determined to be safe, the unsafe threshold is adjusted to the larger side and the maximum distance to the smaller side. On the contrary, if the unconfirmed facility that was judged to be safe is judged to be unsafe, the non-safety threshold is adjusted to the smaller side and the maximum distance is adjusted to the larger side. After that, the same process is repeated according to the passage of time and the number of replies.
