  The network 102 is a telephone line, a wireless network, the Internet, and the like, and connects the monitoring device 400 to the mobile terminal 103 and the monitoring center 200. In the present embodiment, an example is shown in which TCP / IP is used as the communication protocol and IPv4 format is used as the network address format. However, the protocol related to the network of the monitoring system according to the present embodiment is not limited to these, and any protocol may be adopted.

  Next, details of the monitoring center 200 will be described. FIG. 2 is a block diagram showing a functional configuration of the monitoring center 200. As shown in FIG. 2, the monitoring center 200 includes a disaster information acquisition unit 202, a specification unit 203, a command unit 204, a transmission / reception unit 205, a monitoring processing unit 206, a communication control unit 201, and a monitoring device database 207. And a monitor 210.

  The disaster information acquisition unit 202 acquires disaster information from the disaster information providing server 100 via a network. In the present embodiment, when a disaster occurs, the disaster information acquisition unit 202 receives the disaster information transmitted from the disaster information providing server 202 by e-mail, thereby acquiring the disaster information. . However, you may comprise so that disaster information may be acquired by acquisition methods other than an email.

  The specifying unit 203 specifies the monitoring device 400 whose monitoring area is the disaster occurrence area included in the disaster information acquired by the disaster information acquiring unit 202 with reference to a monitoring device database described later.

  In the present embodiment, the monitoring device 400 is specified using the area information included in the disaster information. However, the present invention is not limited to this, and the monitoring device 400 is based on any information included in the disaster information. 400 can be identified. For example, when the monitoring device 400 is specified uniformly only from the area information, it is assumed that the monitoring device 400 that targets a building that has not been damaged particularly in the earthquake-resistant structure is specified. In order to avoid this, buildings with earthquake-resistant structures are not extracted uniformly only from regional information, but earthquake intensity such as “Seismic intensity 3 or higher” is also extracted from disaster information and installed in the surveillance area. The monitoring device 400 can be identified from the seismic intensity of the earthquake and the area information according to the characteristics of the building. In addition, the monitoring device 400 can be specified based on all kinds of information such as tsunami information and typhoon information from disaster information.

  The command unit 204 performs a process of transmitting a disaster status confirmation command that is a command to confirm the disaster status to the monitoring device 400 identified by the identification unit 203.

  The transmission / reception unit 205 receives a captured image of the monitoring area and an abnormal level indicating the level of the disaster situation from the monitoring device 400 or transmits various data to the monitoring device 400. Here, the transmission / reception unit 205 corresponds to the receiving means in the present invention.

  The monitoring processing unit 206 displays a captured image of the monitoring area from the monitoring device 400 received by the transmission / reception unit 205 on a monitor, or executes monitoring processing according to an abnormal level of a disaster situation described later.

  The communication control unit 201 controls communication with the monitoring device 400, the disaster information providing server 100, and the mobile terminal 104 via the network 102, and specifically corresponds to a network board or the like.

  The monitoring device database 207 is a database for managing a plurality of monitoring devices 400 connected to the network 102. FIG. 3 is a data structure diagram showing an example of the contents of the monitoring device database 207.

  As shown in FIG. 3, the monitoring device database 207 includes a monitoring device ID that is identification information unique to the monitoring device 400, a monitoring area that is monitored by the monitoring device 400, and identification information on the network of the monitoring device 400. A certain IP address and the report destination of the administrator of the monitoring apparatus 400 are registered in association with each other. For example, when the monitoring device is connected to an ISDN or an analog telephone line, the identification information is a telephone number of the monitoring device.

  Next, details of the monitoring device 400 will be described. FIG. 4 is a block diagram illustrating a functional configuration of the monitoring apparatus 400. As shown in FIG. 4, the monitoring device 400 according to the present embodiment includes a plurality of sensors 401 a to 401 n, a microphone 402, a speaker 403, an input / output control unit 410, a control unit 420, and a communication control unit 430. And an image storage unit 440, a report destination database 450, and an abnormality level table 460.

  Sensors 401a to 401n are human sensors, for example, an infrared sensor that detects the presence of a person based on a change in the amount of received infrared light, or a blocking sensor that detects the presence of a person by blocking reception of infrared light or the like. These are various sensors for detecting abnormalities in a monitoring area, such as an atmosphere sensor for detecting the presence of a person by disturbance of electromagnetic waves, and a magnet sensor for detecting opening / closing of a door by a magnet.

  The microphone 402 acquires a voice uttered by a human or the like, and the speaker 403 outputs the transmitted voice.

  The input / output control unit 410 is a processing unit that controls input / output of various data by input control of the imaging device 101, sensors 401 a to 401 n, microphone 402, and output control of the speaker 403.

  The image storage unit 440 is a storage medium such as a hard disk drive (HDD), and stores a reference image 441 that is a captured image in a normal situation where no disaster has occurred in the monitoring area. Further, the image storage unit 440 is configured to sequentially store the captured image 442 in the monitoring area captured by the imaging device 101 every time it is captured.

  The control unit 420 controls the entire processing of the monitoring device 400, and mainly includes an image analysis unit 421, an abnormality determination unit 422, an abnormality alarm notification unit 423, and a transmission / reception unit 424.

The image analysis unit 421 performs a known image processing on the captured image 442 and the reference image 441 is intended Mel determined image difference value by comparing the two images. Here, the image difference value uses the number of pixels of the difference between the reference image and the captured image. However, the image difference value is not limited to the number of pixels of the difference, and a luminance difference value or the like may be used.

  The transmission / reception unit 424 performs processing for receiving a damage status confirmation command from the monitoring center 200 and transmitting a captured image and an abnormal level of the damage status to the monitoring center 200. The transmission / reception unit 424 corresponds to transmission means and reception means in the present invention.

  The abnormality determination unit 422 determines whether or not a disaster has occurred in the monitoring area from the image difference value obtained by the image analysis unit 421 when a damage status confirmation command is received from the monitoring center 200. In addition, when the abnormality determination unit 422 determines that a disaster has occurred, the abnormality determination unit 422 performs a process of determining an abnormality level indicating a level of the disaster situation based on the image difference value.

  In this embodiment, the image analysis unit 421 obtains an image difference value between the captured image and the reference image, and the abnormality determination unit 422 determines whether the image difference value causes damage. It may be determined whether or not the disaster is caused only by the captured image. For example, when a monitoring area is damaged, paying attention to the high possibility that an object is scattered, edge detection processing is performed as image analysis processing by the image analysis unit 421, and the edge detection processing is performed by the abnormality determination unit 422. It can be configured to determine that a disaster has occurred when a predetermined number or more of dispersed edges are measured. Here, the captured image, the image difference value, and the abnormality level correspond to information based on the captured image in the present invention.

  The abnormality alarm reporting unit 423 receives the damage status confirmation command, and when the abnormality determination unit 422 determines that a disaster has occurred, the notification destination of the mobile terminal 103 of the manager of the monitoring center 200 and the monitoring device 400 Process to send a disaster warning to. In addition, the abnormality alarm reporting unit 423 outputs an intrusion alarm to the speaker 403 when a situation such as a suspicious person intrusion is detected in the monitoring area by the abnormality determination unit 422 when no damage status confirmation command is received. Perform the process.

  The report destination database 450 is a database in which the report destination of the administrator of the monitoring device 400 is registered, and is stored in a storage medium such as an HDD. FIG. 5 is a data structure diagram showing an example of the report destination database 450. In the report destination database 450, as shown in FIG. 5, an administrator ID, which is identification information unique to the manager, and a report destination such as the portable terminal 103 of the manager are registered in association with each other.

  The abnormality level table 460 is a table that defines a range of image difference values corresponding to the abnormality level indicating the level of the disaster situation. The abnormality level table 460 is referred to when the abnormality determination unit 422 determines the abnormality level. An abnormal level corresponding to a range including the obtained image difference value is determined.

FIG. 6 is a data structure diagram showing an example of the abnormality level table 460. In the abnormality level table, as shown in FIG. 6, the abnormality level, the range of the image difference value, and the degree of damage are associated with each other. In this embodiment, abnormal levels are divided into 0 to 5, abnormal level 0 indicates a state without affected disaster has not occurred (Damage Assessment 0), as a reference level the abnormal level 1, such reference level or more abnormal level (s) shows a state where affected by disaster occurred has occurred.

  The range of the image difference value is a range of the number of pixels of the difference between the reference image and the captured image. In the present embodiment, a range of image difference values (100 or more) corresponding to an abnormality level of 1 or higher is a pixel detected as a difference when an object falls in order to more accurately determine that a disaster has occurred. The value is used as 100.

  The content of the abnormal level table shown in FIG. 6 is an example. The number of abnormal levels, the reference level of the abnormal level determined to be a disaster, and the range of image difference values corresponding to each abnormal level are arbitrary. A value can be used.

  Further, in the present embodiment, in the range of image difference values (0 to 99) in the case of an abnormal level 0 in a state where no disaster has occurred, a person has an image difference value of 50 to 99 (reference level 50). The range is detected as a difference value when moving, and the range of the image difference value for determining that a suspicious person has entered the monitoring area when a disaster has not occurred.

  Next, the monitoring process by the monitoring system according to this embodiment configured as described above will be described. In the monitoring system of the present embodiment, when the monitoring center 200 acquires disaster information from the disaster information providing server 100, the monitoring device 400 that specifies the area where the disaster has occurred is specified as the monitoring area. A damage status confirmation command is transmitted to the monitoring device 400. The monitoring apparatus 400 that has received the damage confirmation command determines whether or not a disaster has occurred by comparing the reference image and the captured image, determines an abnormal level, and if a disaster has occurred, the captured image The abnormal level is transmitted to the monitoring center 200, and a disaster warning is transmitted to the monitoring terminal 200 and the portable terminal 103 of the administrator of the monitoring device 400. And the monitoring apparatus 400 which received the captured image, the abnormal level, and the disaster warning executes a monitoring process according to the abnormal level.

  First, the monitoring process in the monitoring center 200 will be described. FIG. 7 is a flowchart of a monitoring process procedure performed by the monitoring center 200 according to the first embodiment. In the monitoring center 200, the disaster information acquisition unit 202 is waiting to receive disaster information from the disaster information acquisition server 100 (step S701).

  When disaster information is received from the disaster information providing server 100 by the disaster information acquisition unit 202 (step S701: Yes), the specifying unit 203 monitors the regional information included in the received disaster information and the monitoring device database 207. The monitoring device 400 corresponding to the monitoring region of the monitoring device database 207 included in the region of the monitoring device database 207 included in the region of the monitoring device with the same region or the received disaster information is specified (step S702). Specifically, the monitoring device ID of the monitoring device 400 corresponding to the corresponding monitoring area in the monitoring device database 207 is specified.

  Next, the command unit 204 acquires an IP address corresponding to the monitoring device ID of the monitoring device 400 specified by the specifying unit 203 from the monitoring device database 207, and designates this IP address to indicate the disaster situation in the monitoring area. A disaster status confirmation command to be confirmed is transmitted (step S703). The monitoring device 400 that has received the damage status confirmation command determines whether or not a damage has occurred in the monitoring area, as will be described later, and if a disaster has occurred, the imaging device 101 images the damage status. Images, abnormal levels and damage warnings are sent. On the other hand, when no disaster has occurred, an abnormal level 0 indicating that no disaster has occurred and no damage is transmitted.

  Therefore, the transmission / reception unit 205 of the monitoring center 200 determines whether data or a disaster alarm has been received from the monitoring device 400 within a certain time (step S704). Then, when data or a disaster alarm is received by the transmission / reception unit 205 (step S704: Yes), it is determined whether or not the disaster has occurred by checking whether or not the abnormal level in the received data is 1 or more. Is determined (step S705).

  If the abnormal level in the received data is not 1 or higher, that is, if the abnormal level is 0 (step S705: No), it is determined that there is no damage in the monitoring area, and the reception of disaster information is awaited (step S701).

  On the other hand, when the abnormal level in the received data is 1 or more in step S705 (step S705: Yes), it is determined that a disaster has occurred and the captured image in the received data is output to the monitor 210 (step S705). S706). Then, the transmission / reception unit 205 transmits the received disaster warning to the portable terminal 103 that is the report destination of the administrator corresponding to the monitoring device ID of the specified monitoring device 400 (the monitoring device 400 that is the transmission source of the received data) (step) S707). Next, the monitoring processing unit 206 executes monitoring processing according to the received abnormal level (step S708). The monitoring process may be determined in advance corresponding to the abnormal level, and the specific contents of the monitoring process can be arbitrarily determined.

  As a monitoring process according to such an abnormal level, the following process is given as an example. For example, when the abnormal level is lower than a certain reference, the monitoring processing unit 206 displays the captured image from the monitoring device 400 on the monitor and automatically dials the telephone number of the administrator of the monitoring device 400. In the case of the maximum abnormal level, the monitoring processing unit 206 automatically dials the telephone number of the administrator of the monitoring device 400 and the fire department or a preset report destination, and further directs the guard to the monitoring area. In addition, information on the monitoring area is attached to the guard's waiting area (not shown) and a report is made. In addition, the monitoring processing unit 206 performs the above-described automatic dialing in order from the monitoring device 400 having a high abnormality level. In this way, it is possible to perform preferential and appropriate monitoring processing according to the abnormality level.

  In step S704, if nothing is received from the monitoring device 400 within a certain time (step S704: No), the fact that there is no response despite the transmission of the damage status confirmation command indicates that the monitoring device 400 is installed. It is determined that the disaster situation is more severe as the communication state is paralyzed in a certain area, and the monitoring processing unit 206 executes monitoring processing corresponding to the maximum abnormal level (step S709).

  Next, the monitoring process in the monitoring apparatus 400 that has received the damage status confirmation command in step S703 will be described. FIG. 8 is a flowchart showing the procedure of the monitoring process by the monitoring apparatus 400.

  First, in the monitoring apparatus 400, it is determined whether or not a disaster status confirmation command has been received from the monitoring center 200 by the transmission / reception unit 424 (step 801). When a damage confirmation command is received from the monitoring center 200 (step S801: Yes), the image analysis unit 421 acquires a captured image of the current monitoring area from the imaging device 101 via the input / output control unit 410. (Step S802). Then, the image analysis unit 421 performs known image analysis processing (step S803).

  As the image analysis processing, for example, contrast optimization processing (processing for expanding gray scale gradation and reducing bias, etc.) for imaged image data, edge detection processing (specifically, for each pixel of image data) Each process such as a process for detecting an edge by calculating a change amount of a pixel value with respect to a neighboring pixel based on one pixel is performed. However, the image analysis process is not limited to this, and other image processes may be executed.

  Next, the image analysis unit 421 compares the captured image with a reference image 441 that is a captured image of a normal monitoring area in which no disaster has occurred and is stored in the image storage unit 440 to calculate an image difference. Processing is performed to obtain an image difference value (step S804).

  Next, the abnormality determination unit 422 determines whether or not the image difference value is equal to or greater than a first threshold (step S805). Here, the first threshold value is a threshold value for determining whether or not a disaster has occurred in the monitoring area. In the present embodiment, a value 100 that appears as an image difference value when an object falls is set to the first threshold value. Used as a threshold. That is, if the image difference value between the captured image obtained by the image analysis unit 421 and the reference image 441 is 100 or more, it is determined that there is at least a damage that causes the object to fall. For this reason, in the abnormal level table 460 shown in FIG. 6, an image difference value of less than 100 is set as an abnormal level 0 as no damage, and an image difference value of 100 or more is set as an abnormal level 1 or higher as damaged.

  In step S805, if the image difference value is less than 100 (step S805: No), the abnormality determination unit 422 determines that there is no damage, and the transmission / reception unit 424 indicates that no disaster has occurred and no damage has occurred. An abnormal level 0 indicating that is transmitted to the monitoring center 200 (step S809).

  On the other hand, if the image difference value is 100 or more in step S805 (step S805: Yes), the abnormality determination unit 422 determines that a disaster has occurred and refers to the abnormality level table 460 to determine the image difference value. Determines an abnormal level corresponding to “range of image difference values” (step S806).

Then, the abnormality alarm notification unit 423 transmits a disaster alarm indicating that the disaster has occurred to the monitoring center 200 (step S807), and the transmission / reception unit 424 determines the captured image of the current monitoring area and the abnormality determination unit 422. The abnormal level thus transmitted is transmitted to the monitoring center 200 (step S808). Thus, it is possible to grasp the disaster situation to the monitoring center 200. In this embodiment, the captured image and the abnormal level are transmitted to the monitoring center 200, but instead of transmitting the abnormal level, the image difference value and the captured image obtained in step S804 are used as the monitoring center. Alternatively, it may be configured such that only the image difference value is transmitted to the monitoring center 200. In this case, whether or not a disaster has occurred on the monitoring center 200 side may be determined based on the image difference value.

  Returning to step S801, if the disaster confirmation command has not been received from the monitoring center 200 (step S801: No), the monitoring device 400 performs normal monitoring processing when no disaster has occurred (step S810). .

  Next, the normal monitoring process will be described. FIG. 9 is a flowchart illustrating a procedure of normal monitoring processing by the monitoring apparatus 400. First, the abnormality determination unit 422 determines whether an abnormality signal is input from the sensors 401a to 402n via the input / output control unit 410 (step S901). Then, while no abnormal signal is input (step S901: No), the process returns to step S801 in FIG.

  On the other hand, when the abnormality determination unit 422 determines that an abnormality signal has been input from the sensors 401a to 402n (step S901: Yes), the image analysis unit 421 performs input / output control of the captured image of the current monitoring region from the imaging device 101. Obtained via the unit 410 (step S902), and image analysis processing similar to step S803 is performed (step S903).

  In this embodiment, the captured image is acquired when it is determined that an abnormal signal is input from the sensors 401a to 402n. However, the present invention is not limited to this, and the sensors 401a to 402n are not used. In addition, when it is determined that the monitoring area is abnormal, the image analysis unit 421 may acquire a captured image of the current monitoring area from the imaging apparatus 101.

  Next, the image analysis unit 421 compares the captured image with the reference image 441 stored in the image storage unit 440, performs image difference calculation processing, and obtains an image difference value (step S904).

  Next, the abnormality determination unit 422 determines whether or not the image difference value is equal to or greater than a second threshold value that is smaller than the first threshold value (step S905). Here, the second threshold value is a threshold value for determining whether or not an abnormal state such as a suspicious person invading has occurred, although a disaster has not occurred in the monitoring area. Then, a value 50 that appears as an image difference value when a person moves, such as when a suspicious person enters and an object falls, is used as the second threshold value. That is, if the image difference value between the captured image obtained by the image analysis unit 421 and the reference image 441 is 50 or more (less than 100), it is determined that a suspicious person may have entered.

  In step S905, if the image difference value is less than 50 (step S905: No), the abnormality determination unit 422 determines that there is no abnormality in the monitoring area, and returns to step S801 in FIG. Waiting for receipt of damage status confirmation command.

  On the other hand, in step S905, when the image difference value is 50 or more (step S905: Yes), the abnormality determination unit 422 determines that the suspicious person has entered the monitoring area, and the abnormality alarm notification unit 423 determines whether the suspicious person has entered. An intrusion alarm indicating the intrusion is output to the speaker 403 via the input / output control unit 410 (step S906). Then, the abnormality alarm reporting unit 423 transmits an intrusion alarm to the portable terminal 103 that is the reporting destination of the administrator registered in the reporting destination table 450 (step S907). As a result of such processing, the monitoring device 400 executes normal monitoring processing while the disaster status confirmation command is not received.

As described above, in the monitoring system according to the first embodiment, when the monitoring center 200 acquires the disaster information from the disaster information providing server 100, the monitoring apparatus 400 that uses the area where the disaster occurs as a monitoring area confirms the damage status. The monitoring device 400 that has transmitted the command and received the damage status confirmation command determines whether or not a disaster has occurred by comparing the reference image of the normal monitoring area where the disaster has not occurred with the current captured image. When a disaster occurs, the captured image, the abnormal level indicating the level of the disaster situation, and the disaster warning are transmitted to the monitoring center 200, and the monitoring center 200 executes a monitoring process according to the abnormal level of the disaster situation. Therefore, the captured image is transmitted to the monitoring center only when a disaster actually occurs, so the amount of data transmission is reduced and multiple monitoring on the monitoring center side are performed. It is possible to realize labor saving centralized monitoring area.

  Further, in the monitoring system according to the first embodiment, when the monitoring device 400 determines an abnormal level indicating the level of the damage status based on the image difference value and determines that the monitoring area is damaged, Since the captured image is transmitted to the monitoring center together with the determined abnormal level, the monitoring center 200 can grasp the abnormal level of the disaster situation, and performs preferential and appropriate monitoring processing according to the level of the disaster situation. be able to.

(Embodiment 2)
In the monitoring system according to the first embodiment, when the monitoring device 400 receives the damage status confirmation command, all the captured images of the disaster status are transmitted to the monitoring center 200. However, in the monitoring system according to the second embodiment, Only when the abnormal level is equal to or higher than a certain reference level, the captured image of the disaster situation is transmitted to the monitoring center 200.

  The network configuration of the monitoring system according to the second embodiment and the functional configurations of the monitoring center 200 and the monitoring device 400 are the same as those of the first embodiment.

  In the monitoring apparatus 400 according to the present embodiment, the transmission / reception unit 424 determines whether or not the abnormality level determined by the abnormality determination unit 422 is equal to or higher than a reference level. The level is transmitted to the monitoring center 200, and when the level is less than the reference level, processing is performed to transmit only the abnormal level to the monitoring center 200 without transmitting the captured image of the disaster situation.

  In the monitoring center 200 according to the present embodiment, the monitoring processing unit 206 determines whether or not the captured image is included in the data received from the monitoring device 400.

  Next, the monitoring process in the monitoring apparatus 400 that has received the damage confirmation command in the present embodiment configured as described above will be described. FIG. 10 is a flowchart of a monitoring process performed by the monitoring apparatus 400 according to the second embodiment.

  The processing (steps S1001 to S1007, S1011) from waiting for receiving the disaster status confirmation command from the monitoring center 200 to the transmission of the disaster alarm to the portable terminal 103 by the monitoring device 400 according to the first embodiment ( Steps S801 to S807 and S809) are performed in the same manner. Also, the normal monitoring process (step S1012) is performed in the same manner as the process (step S810) by the monitoring apparatus 400 of the first embodiment.

  When the disaster warning is transmitted to the administrator's portable terminal 103, the transmission / reception unit 424 determines whether or not the abnormality level is 3 or more, which is the reference level (step S1008). Here, although the reference level is set to 3 in the present embodiment, the present invention is not limited to this, and any level can be set as the reference level.

  In step S1008, when the abnormal level is 3 or more which is the reference level (step S1008: Yes), the transmission / reception unit 424 transmits both the captured image of the disaster situation and the abnormal level to the monitoring center 200 ( Step S1009).

  On the other hand, when the abnormal level is less than the reference level of 3 (step S1008: No), the transmission / reception unit 424 transmits only the abnormal level to the monitoring center 200 without transmitting the captured image of the disaster situation (step S1008: No). S1010). Thereby, the captured image of the disaster situation is transmitted to the monitoring center 200 only when the level of the disaster situation is an abnormal level higher than the reference level.

  Next, monitoring processing by the monitoring center 200 that has received a captured image or an abnormal level will be described. FIG. 11 is a flowchart of a monitoring process procedure performed by the monitoring center 200 according to the second embodiment.

  In the monitoring center 200, processing from waiting for receiving disaster information to determining whether or not the abnormal level in the received data for the damage status confirmation command to the monitoring device 400 is 1 or more (whether or not a disaster has occurred) (Steps S1101 to S1105, S1110) are performed in the same manner as the processing (Steps S701 to S705, S709) of the monitoring center 200 of the first embodiment.

  In step S1105, when the abnormal level in the received data is 1 or more (step S1105: Yes), the monitoring processing unit 206 checks whether or not the captured data is included in the received data from the monitoring device 400. (Step S1106). When the captured image is included in the received data (step S1106: Yes), the monitoring processor 206 outputs the captured image in the received data to the monitor 210 (step S1107).

  On the other hand, in step S1106, when the captured image is not included in the received data (step S1106: No), the captured image is not output to the monitor 210.

  Then, in the same manner as in the first embodiment, the transmission / reception unit 205 receives the received information on the mobile terminal 103 that is the report destination of the administrator corresponding to the monitoring device ID of the specified monitoring device 400 (the monitoring device 400 that is the transmission source of received data) The disaster warning is transmitted (step S1108), and the monitoring processing unit 206 executes monitoring processing according to the received abnormality level (step S1109).

  As described above, in the monitoring system according to the second embodiment, the monitoring device 400 transmits the captured image of the disaster situation to the monitoring center 200 only when the abnormal level of the disaster situation is equal to or higher than a certain reference level. Since the captured image is output to the monitor, only the captured image having a high level of damage and having a damage status equal to or higher than the reference level can be transmitted, and the monitoring process according to the level of the damage status can be performed on the monitoring center 200 side. At the same time, the amount of data transmission can be further reduced.

(Embodiment 3)
In the monitoring system according to the first and second embodiments, when the monitoring device 400 receives the damage status confirmation command, the captured image of the disaster status is transmitted to the monitoring center 200 together with the abnormal level. In such a monitoring system, only the abnormal level is transmitted from the monitoring device 400 to the monitoring center 200, and when the captured image is requested from the monitoring center 200, the captured image is transmitted to the monitoring center 200.

  The network configuration of the monitoring system according to the third embodiment and the functional configurations of the monitoring center 200 and the monitoring device 400 are the same as those of the first embodiment.

  In the monitoring apparatus 400 of the present embodiment, the transmission / reception unit 424 first transmits the abnormality level determined by the abnormality determination unit 422 to the monitoring center 200. Then, the transmission / reception unit 424 performs processing for transmitting the captured image of the disaster situation to the monitoring center 200 when a request for the captured image is received from the monitoring center 200.

  Further, in the monitoring center 200 according to the present embodiment, the transmission / reception unit 205 further exceeds the second reference level where the abnormal level is a certain level when the abnormal level received from the monitoring device 400 is a level where the disaster has occurred. If it is equal to or higher than the second reference level, a request for a captured image is transmitted to the monitoring device 400, and a captured image transmitted in response to the request for the captured image is received. Processing is in progress.

  Next, the monitoring process in the monitoring apparatus 400 that has received the damage confirmation command in the present embodiment configured as described above will be described. FIG. 12 is a flowchart of a monitoring process performed by the monitoring apparatus 400 according to the third embodiment.

  The processing (steps S1201 to S1207, S1211) from waiting for receipt of the damage status confirmation command from the monitoring center 200 to the transmission of the damage alarm to the portable terminal 103 by the monitoring device 400 according to the first embodiment ( Steps S801 to S807 and S809) are performed in the same manner. Further, the normal monitoring process (step S1212) is performed in the same manner as the process (step S810) by the monitoring apparatus 400 of the first embodiment.

  When the disaster warning is transmitted to the administrator's portable terminal 103, the transmission / reception unit 424 transmits the abnormality level determined by the abnormality determination unit 422 to the monitoring center 200 (step S1208). Then, the transmission / reception unit 424 determines whether a request for a captured image has been received from the monitoring center 200 within a predetermined time (step S1209). If a request for a captured image is not received from the monitoring center 200 within a certain time (step S1209: No), the process waits for receiving a damage status confirmation command from the monitoring center 200 (step S1201).

  On the other hand, when a request for a captured image is received from the monitoring center 200 within a certain time (step S1209: Yes), the captured image is transmitted to the monitoring center 200 by the transmission / reception unit 424 (step S1210).

  Next, monitoring processing by the monitoring center 200 that has received the abnormal level will be described. FIG. 13 is a flowchart of a monitoring process performed by the monitoring center 200 according to the third embodiment.

  In the monitoring center 200, processing from waiting for receiving disaster information to determining whether or not the abnormal level in the received data for the damage status confirmation command to the monitoring device 400 is 1 or more (whether or not a disaster has occurred) (Steps S1301 to S1305 and S1312) are performed in the same manner as the processing (Steps S701 to S705 and S709) of the monitoring center 200 of the first embodiment.

  In step S1305, when the abnormal level in the received data is 1 or more (step S1305: Yes), the transmission / reception unit 205 further determines whether the received abnormal level is 3 or more, which is the second reference level. It investigates (step S1306). If the received abnormality level is 3 or more, which is the second reference level (step S1306: Yes), the transmission / reception unit 205 transmits a request for a captured image of the disaster situation to the monitoring device 400 (step S1307). Then, it waits to receive a captured image from the monitoring device 400 (step S1308).

  Next, when the transmission / reception unit 205 receives a captured image of the disaster situation from the monitoring device 400 (step S1308: Yes), the monitoring processing unit 206 outputs the captured image in the received data to the monitor 210 (step S1309). .

  Here, if the abnormal level is less than 3 which is the second reference level in step 1306 (step S1306: No), transmission of the request for the captured image, reception of the captured image, and output to the monitor 210 are not performed. I will not.

  Next, in the same manner as in the first embodiment, the transmitter / receiver 205 causes the administrator's report destination mobile terminal 103 corresponding to the monitoring device ID of the specified monitoring device 400 (the monitoring device 400 that is the transmission source of received data) to The received disaster warning is transmitted (step S1310), and the monitoring processing unit 206 executes monitoring processing according to the received abnormal level (step S1311).

  As described above, in the monitoring system according to the third embodiment, only the abnormal level is transmitted from the monitoring device 400 to the monitoring center 200, and when the captured image is requested from the monitoring center 200, the captured image is transmitted to the monitoring center 200. Since the monitoring image is output to the monitor on the monitoring center 200 side, it is determined that the monitoring area is damaged, and the monitoring device 400 captures an image only when the monitoring center 200 requires it. It is only necessary to transmit an image, and the amount of data transmission can be reduced, and labor saving of centralized monitoring of a plurality of monitoring areas on the monitoring center 200 side can be realized.

  The monitoring center 200 of the present embodiment includes a control device such as a CPU, a storage device such as a ROM (Read Only Memory) and a RAM, an external storage device such as an HDD and a CD drive device, and a display device such as a display device. It has an input device such as a keyboard and a mouse, and has a hardware configuration using a normal computer.
