  According to the present invention, it is possible to monitor a building and a detailed damage situation in the vicinity of the building that are expected to suffer an earthquake disaster with images.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows a system configuration diagram of an earthquake situation monitoring system according to an embodiment of the present invention. In the example shown in FIG. 1, there are a condominium 1A, a condominium 1B, and a condominium 1C in the jurisdiction of the local government. In addition, a camera 9A that monitors the apartment 1A, a camera 9B that monitors the apartment 1B, and a camera 9C that monitors the apartment 1C are installed.

  In the embodiment of the present invention, an apartment has been described as an example. However, it is not necessary to use an apartment, and any building that should be monitored when an earthquake occurs may be used.

  The cameras 9 such as the cameras 9A, 9B, and 9C may be, for example, a web camera or a security camera installed near the entrance of an apartment, but are not limited to a disaster prevention camera. The installation location of the camera 9 may be any location as long as the situation of the disaster can be understood.

  In the earthquake situation monitoring system shown in FIG. 1, video data transmitted from the camera 9 via the network is received by the earthquake situation monitoring apparatus 10 in the monitoring center and displayed on the display device of the earthquake situation monitoring apparatus 10. . The earthquake information server 20 distributes earthquake information to the earthquake situation monitoring apparatus 10 via a network.

  The earthquake information is information relating to the seismic intensity of the jurisdiction of the local government for which notification is determined in advance or the seismic intensity of each place when an earthquake occurs. Furthermore, information regarding the epicenter and the seismic intensity of the epicenter may be included.

  Here, the apparatus block diagram of the earthquake condition monitoring apparatus 10 which concerns on embodiment of this invention is shown in FIG. The seismic situation monitoring device 10 is shown in FIG. 1, for example, a control unit 11 composed of a CPU for executing a program, a memory 12 composed of ROM, RAM, etc., a database 13 for managing seismic values indicating the degree of seismic resistance of buildings. The network interface 14 for transmitting and receiving information via the network, the input unit 15 including a keyboard and a mouse, and the display device 16 execute an earthquake condition monitoring method. The database 13 includes storage means such as a hard disk and a memory and a program for managing data.

  Further, the video reception unit 17, the earthquake information reception unit 18, the risk level determination unit 19, the risk level determination unit 21, and the display control unit 22 illustrated in FIG. 2 are, for example, program modules and are executed by the control unit 11. Is done.

  The video receiving unit 17 receives video data indicating a condominium in the jurisdiction of the local government or a surrounding state including the apartment via the network interface 14. The video data received by the video receiver 17 is transmitted from the camera 9A, camera 9B, and camera 9C.

  The earthquake information receiving unit 18 receives earthquake information about the seismic intensity in the jurisdiction of the local government from the earthquake information server 20 or an earthquake detector (not shown) via the network interface 14 when an earthquake occurs. The earthquake information may include information in addition to the seismic intensity in the jurisdiction. For example, as other information, the seismic intensity and the seismic intensity at the epicenter may be used. Further, the earthquake information may be information that can specify an expected seismic intensity and an expected arrival time of an earthquake within a jurisdiction area.

  The risk level specifying unit 19 specifies the risk level of the apartment based on the seismic intensity and the seismic value. The seismic intensity processed by the risk specifying unit 19 is the one received when the earthquake information receiving unit 18 receives the seismic value processed by the risk specifying unit 19 in each jurisdiction managed in the database 13. The seismic value of the apartment.

  For example, an example of the seismic value managed in the database 13 is shown in FIG. In the example shown in FIG. 3, there are seismic values corresponding to the apartment 1 </ b> A, the apartment 1 </ b> B, and the apartment 1 </ b> C. In the embodiment of the present invention, the smaller the value, the stronger the earthquake. That is, among the apartment 1A, the apartment 1B, and the apartment 1C, the apartment 1A has a structure that is most resistant to earthquakes, and the apartment 1C has a structure that is most resistant to earthquakes. The earthquake resistance value is one index value indicating the degree of earthquake resistance.

  If the example shown in FIG. 3 is used, the risk identification part 19 will calculate a risk with the calculation formula which shows the relationship between a seismic value and a seismic intensity. In addition, the greater the risk, the more susceptible to the earthquake. The degree of danger is one index value indicating the degree of danger.

  If the seismic value is X and the seismic intensity is Y, the risk level can be expressed by a function f (X, Y) that increases as X increases and increases as Y increases. . For example, the degree of risk can be expressed by the following linear function (calculation formula). Risk = f (X, Y) = αX + βY (α and β are positive constants). The degree of risk may be expressed by a non-linear function. Further, instead of the function, a table (so-called look-up table) for determining the degree of risk from X and Y may be used.

  The risk determination unit 21 determines whether or not the risk of each apartment specified by the risk specification unit 19 is equal to or greater than a predetermined threshold.

  The display control unit 22 displays the video of the camera 9 on the display device 16 from the data received by the video reception unit 17. Further, the display control unit 22 causes the display device 16 to display an image corresponding to each apartment whose risk level is equal to or greater than a threshold value.

  If it is determined that the risk level of each of the plurality of buildings is equal to or higher than the threshold value, a predetermined number of risk levels are selected from the risk level in descending order, and an image corresponding to the selected risk level is displayed. May be.

  An example of the operation of the earthquake condition monitoring apparatus 10 according to the embodiment of the present invention configured as described above will be described with reference to the drawings. FIG. 4 is a flowchart showing the operation of the earthquake situation monitoring apparatus 10 according to the embodiment of the present invention.

  4A, first, when the earthquake information receiving unit 18 receives earthquake information (S1), the risk specifying unit 19 selects one apartment, and acquires the seismic value of the selected apartment from the database 13. (S2).

  Based on the acquired seismic value and the seismic intensity of the earthquake information received by the earthquake information receiving unit 18, the risk specifying unit 19 calculates the risk using the calculation formula as described above (S3). The risk determination unit 21 determines whether or not the apartment risk calculated by the risk determination unit 19 is equal to or greater than a threshold (S4).

  When it is determined that the degree of risk is greater than or equal to the threshold, the display control unit 22 causes the display device 16 to display an image corresponding to the apartment when it is determined that the risk is greater than or equal to the threshold (S5). Subsequently, the risk specifying unit 19 confirms whether or not there is an unselected apartment (S6), selects the next apartment from among the unselected apartments, and repeats the processes after S2. If all apartments have been selected, the process ends.

  Here, in the apartment 1A, the apartment 1C, the apartment 1C, and the apartment 1C whose risk level is determined to be greater than or equal to the threshold is the apartment 1C as shown in FIG. 5A. 16 is displayed. If it is all apartments that have been determined that the degree of risk is greater than or equal to the threshold, images of all apartments are displayed on the display device 16.

  Thus, FIG. 4B showing a process for limiting the number of videos will be described. In addition, the same code | symbol is attached | subjected to the same thing as the process of Fig.4 (a).

  First, when the earthquake information receiving unit 18 receives earthquake information (S1), the risk specifying unit 19 selects one apartment and acquires the seismic value of the selected apartment from the database 13 (S2).

  Based on the acquired seismic value and the seismic intensity of the earthquake information received by the earthquake information receiving unit 18, the risk specifying unit 19 calculates the risk using the calculation formula as described above (S3). The risk determination unit 21 determines whether or not the apartment risk calculated by the risk determination unit 19 is equal to or greater than a threshold (S4).

  When it is determined that the risk level is equal to or higher than the threshold value, the display control unit 22 stores identification information for identifying the apartment and the risk level when it is determined to be equal to or higher than the threshold value in the memory 12 (S7). Subsequently, the risk specifying unit 19 confirms whether or not there is an unselected apartment (S6), selects the next apartment from among the unselected apartments, and repeats the processes after S2.

  When all the condominiums are selected, the display control unit 22 assigns the display order to the apartment images in descending order of the risk level among the risk levels stored in the memory 12 (S8). Next, the display control unit 22 displays apartment images up to a predetermined number (referred to as the display number) in accordance with the display order (S9).

  For example, it is assumed that the condominium 1A, the condominium 1B, and the condominium 1C are determined to have a risk level equal to or higher than the threshold, and the condominium 1C, the condominium 1B, and the condominium 1A are in descending order. Therefore, the display order is also the order of the apartment 1C, the apartment 1B, and the apartment 1A. In this case, when the number of displays is 2, two images of the apartment 1C and the apartment 1B are displayed on the display device 16 as shown in FIG. In other words, the video is limited by the number of displays.

  The display control unit 22 stores the risk level of each apartment regardless of whether the risk level is equal to or higher than the threshold value, and selects a predetermined number of risk levels in descending order from the risk level. A video corresponding to the degree of danger may be displayed.

  As described above, according to the earthquake situation monitoring apparatus 10 according to the embodiment of the present invention, if the degree of risk is equal to or greater than the threshold, the display device 16 displays an image showing the apartment or the surrounding area including the apartment. It is possible to monitor the detailed damage situation of apartments and condominiums that are expected to suffer serious earthquake disasters. In addition, since the risk level is selected in descending order and the video corresponding to the selected risk level is displayed, the screen size of the display device 16 is limited and a large number of videos cannot be displayed. The number of displays can be limited and displayed efficiently.
