[Embodiment 1]
Based on FIGS. 1-8, the disaster prevention support system which concerns on this Embodiment is demonstrated. First, based on FIGS. 1-3, the structure of the disaster prevention assistance system which concerns on this Embodiment is demonstrated.

  FIG. 1 shows a building which is a fire prevention object provided with the disaster prevention support system of the present invention, and the evacuation route includes obstacle information including position information and discovery time for an obstacle on the evacuation route. As an obstacle information collecting means for collecting and transmitting the information, a monitoring camera 5 and an obstacle sensor 6 are provided.

  The monitoring camera 5 monitors the evacuation route, is connected to the image receiving device 4, and sends out a captured image signal thereto. The monitoring camera 5 and the image receiving device 4 are connected by a signal cable. However, a wireless communication device may be provided for both to communicate using a wireless signal.

  The obstacle sensor 6 monitors the visual field of the monitoring camera 5 and is connected to the obstacle monitoring device 3 to send an obstacle detection signal to the obstacle monitoring device 3 when an obstacle is detected. The obstacle sensor 6 and the obstacle monitoring device 3 are connected by a signal cable. However, a wireless communication device may be provided on the obstacle sensor 6 to communicate with the wireless signal.

  The monitoring camera 5, the image receiving device 4, the obstacle sensor 6, and the obstacle monitoring device 3 constitute an obstacle information collecting unit. Among these, the image receiving device 4 and the obstacle monitoring device 3 do not need to be provided in the evacuation route, and are provided, for example, in the disaster prevention center.

  The support server 1 is a signal that is disposed in a disaster prevention center or the like, is connected to an obstacle monitoring device 3 and a display unit 2 that is a display unit, and is a communication unit that receives obstacle information transmitted by the obstacle monitoring device 3. Received by the receiver 1a. The information processing unit 1b is a determination unit that determines the degree of an obstacle based on the position and size of the obstacle and outputs a determination result when the obstacle information is received via the signal reception unit 1a. The information processing unit 1b is also an information processing unit that generates caution information described later. The determination result is displayed on the display unit 2 connected thereto via the information processing unit 1b. The storage unit 1c is a storage unit that stores the determination result and the received obstacle information in association with each other. Further, the information processing unit 1b of the support server 1 is connected to an operation unit K that is an input means, and can input information artificially. The information processing unit 1b is connected to a communication unit 1d connected to the network N, and can communicate with the patrol guard terminal M1 and the terminals M2 to Mn (n is a natural number) via the network N. The communication unit 1d is a notification unit that delivers obstacle information, obstacle warning information described later, and caution information described later to the patrol guard terminal M1 and the terminals M2 to Mn. The obstacle from the patrol guard terminal M1 It is also a communication means for receiving information. The network N may be a public network or a dedicated LAN that constructs a network only in a building. Moreover, although the network N may perform wired communication with a cable, it is desirable to perform wireless communication that allows the patrol guard terminal M1 and the terminals M2 to Mn to move freely. (See FIG. 2).

  The patrol guard terminal M1 is a terminal device that is used when the patrol guard possesses the patrol guard and receives and displays the patrol route generated by the information processing unit 1b of the support server 1. The terminals M2 to Mn (n is a natural number) are possessed by disaster prevention personnel such as fire prevention managers, and the obstacle information, the obstacle warning information described later, from the support server 1 through the communication unit 1d and the network N, It is a terminal device that receives and displays information such as important information. It is desirable to connect to the network N by wireless communication in view of the fact that it is always possessed so that information can be received even at the destination and that it can be moved for patrol security (see FIG. 1).

  Since the patrol guard terminal M1 and the terminals M2 to Mn can be common hardware, the M1 and M2 to Mn in that case are hereinafter collectively referred to as the terminal M.

  FIG. 3 shows an example in which the terminal M2 to Mn for the patrol guard terminal M1 and the disaster prevention officials to receive information are configured by the terminal M which is common hardware. For example, they can be configured with a communication terminal called a commercially available smartphone.

  The terminal M includes a communication unit Mb as a communication unit that communicates by connecting to the network N, and a position detection unit Mc that is a position detection unit using GPS or the like. As this position detection means, the most recent access point in the network N in which communication with the terminal M is established may be used. The terminal M includes a display unit Md as a display unit for displaying characters and images, an operation unit Me as an input unit that is a man-machine interface for inputting information, and a camera device Md as an image capturing unit. The display unit Md and the operation unit Me may be integrated using a touch panel. And the terminal M is connected to said Mb-Md, and has the control part Ma which is a control means which controls the whole terminal M (refer FIG. 3).

  Next, the operation of the disaster prevention support system according to the present embodiment will be described with reference to FIGS.

  When the obstacle sensor 6 installed to detect an obstacle in the field of view of the monitoring camera 5 that monitors the evacuation route detects the obstacle X2 (see FIG. 1), the obstacle sensor 6 monitors the obstacle detection signal. The data is sent to the device 3 (S101). The obstacle monitoring device 3 that has received the obstacle detection signal receives the image data of the monitoring camera 5 corresponding to the obstacle sensor 6 that has transmitted the obstacle detection signal via the image receiving device 4 and receives the support server 1. The support server that received and received the image data stores the position information and the discovery time together with the image data as obstacle information in the storage unit 1c (S102).

  In addition, in the case where an erroneous detection such that a person enters the monitoring range of the obstacle sensor 6 and is detected as an obstacle occurs, a human sensor (not shown) for monitoring the monitoring range of the obstacle sensor 6 is provided. While the human sensor detects the presence of a person, the obstacle detection signal of the obstacle sensor 6 is temporarily ignored, or the following warning level determination operation associated with the obstacle detection is temporarily suspended. You may make it. Then, when the person leaves, the normal obstacle detection operation is restored.

  Next, with reference to FIG. 5, an operation for determining the degree of failure due to the obstacle X2 based on the obstacle information received by the support server 1 and setting the warning level according to the determined degree of failure will be described. . In other words, the support server 1 is also a determination unit that determines the degree of failure, and the information processing unit 1b of the support server 1 performs this process. Here, for convenience of explanation, it is assumed that three warning levels (large, medium, and small) are set. However, the present invention is not limited to this, and it depends on how the warning is issued depending on the degree of failure. It is determined appropriately.

  First, the support server 1 determines from the position information included in the received obstacle information whether the position of the obstacle X2 is a position that hinders the closing of automatic closing devices such as fire doors, fire shutters, and smoke shutters. It is determined whether or not (S201). If an obstacle is placed in such a place, the automatic closing device that is controlled to be closed in conjunction with the fire cannot be closed, and the fire spreads or smoke from the fire flows in, evacuating. Since there is a possibility that the route cannot be used, the degree of failure is large, and the warning level is set to the maximum “large” (S202).

  In the above determination (S201), when the obstacle X2 is in a position that does not interfere with the closing of the automatic closing device, the support server 1 performs image processing in the information processing unit 1b to determine the size of the obstacle, The degree of failure is determined by the size. For example, if the size of the obstacle is such that the evacuation route width is completely blocked, it is obvious that the degree of the obstacle is large, and the warning level increases as the proportion of the width of the obstacle X2 in the evacuation route width increases. Setting is performed (S204 to S206).

  In other words, the information processing unit 1b of the support server 1 determines the degree of the obstacle based on the position and size of the obstacle when receiving the obstacle information, and outputs a warning level as a determination result. It is.

  In order to detect the obstacles as described above, it is desirable that the obstacle sensor 6 and the monitoring camera 5 are provided at a position for monitoring the trajectory closed by the automatic closing device and a position for monitoring the direction of travel of the evacuation route.

  Next, a high risk time zone is determined, and a risk according to the time when the obstacle X2 is found is determined. The high-risk time zone indicates a high-risk time zone when there is a failure in the evacuation route, and differs depending on how the building that is a fire prevention object is used. For example, in department stores outside business hours (for example, at night), there is no possibility that ordinary customers are in the building, so the risk during this time period is small, and conversely, the business hours of department stores are high risk hours. . In hotels, nighttime is a high-risk time for guests. From such a viewpoint, the high risk time zone is appropriately determined according to the use form of the building.

  Then, it is determined whether or not the time zone in which the obstacle X2 is found is a high risk time zone (S207). If it is a high risk time zone, the previously determined warning level (S204 to S206) is maintained (Yes in S207), and if it is not a high risk time zone (No in S207), it is determined first. The warning level is reduced by one step from the warning level (S204 to S206).

  Note that the adjustment of the warning level as described above is merely an example, and the warning level may be adjusted as appropriate depending on whether or not it is a high-risk time period. For example, the warning level may be added when the obstacle X2 is in a position where it is difficult to close the automatic closing device or when the obstacle X2 is found in a high risk time zone.

  As described above, when an obstacle is found, the support server 1 determines a warning level for the obstacle, associates it with the corresponding obstacle information, and stores it in the storage unit 1c as obstacle warning information. (S209).

  Next, with reference to FIG. 6, the operation | movement which produces | generates caution information based on the memorize | stored obstacle warning information, and notifies a disaster prevention person concerned is demonstrated.

  The support server 1 refers to the obstacle warning information periodically stored in the storage unit 1c every time a predetermined period elapses, and extracts the position with a high occurrence frequency or warning level to generate “careful information” Then, the person concerned with disaster prevention is notified (S401, S403).

  In other words, the stored obstacle warning information is the information stored in the storage unit 1c in association with the obstacle information and the warning level determination result. Further, the information processing unit 1b of the support server 1 sets a position where the degree of obstacle is large and a position where obstacles are frequently placed based on the obstacle warning information as a position requiring attention. The information processing unit 1b of the support server 1 is an information processing unit that extracts a tendency of a time zone in which an obstacle is placed at a position requiring attention and periodically creates a report as attention information.

  The timing for notifying the attention information may be a predetermined time such as immediately before the start time. By doing in this way, the disaster prevention person H2 (see Fig. 1) who is in charge of the relevant area can confirm the site and instruct corrective action, and also call attention to the person concerned in the area at the morning meeting. Can be encouraged. When the notification to the disaster prevention personnel is completed, the operation of the disaster prevention support system returns to the normal monitoring state (next step of S403).

  In addition, during the patrol guard described later, since the obstacle information is being collected, the generation and notification of the caution information is suspended until this is finished (S402). Therefore, when the timing to generate caution information and notify the disaster prevention personnel is known in advance, it is desirable to set a patrol guard time zone so as to avoid this time zone.

  Next, with reference to FIG. 7, an operation for immediately notifying obstacle-related persons of obstacle warning information when an obstacle is found will be described. Such an operation is important in that a quick response is required in a hotel where people are always staying in the building.

  Before entering this operation, the obstacle warning information is generated according to the degree of the obstacle X2 (S209). First, a response instruction is added together with all the obstacle warning information, and the disaster prevention person H2 (see FIG. 1) in charge of the corresponding district is notified via the communication unit 1d (S301). In other words, the obstacle warning information for the disaster prevention personnel who manage the corresponding area requests a report of a response result including a response instruction for the obstacle.

  Subsequently, all the obstacle warning information is notified to a fire prevention manager such as a fire prevention manager via the communication unit 1d (S302), and further, the occurrence of the obstacle and its position information are notified via the communication unit 1d. Then, it notifies the other disaster prevention personnel H3-4 (see FIG. 1) as obstacle warning information (S303).

  Since these notifications are performed continuously, they are practically broadcast notifications. And it provides necessary information according to the position (responsible district and authority) of disaster prevention personnel and supports them so that they can play the role of fire prevention management.

  The disaster prevention person H2 (see FIG. 1) who has received the obstacle warning information of the area in charge returns whether or not to respond to the response instruction. For example, a reply is made by operating one of the buttons “available” and “not available” displayed on the touch panel of a smartphone which is the portable terminal M2 (see FIG. 1).

  When a response “Available” is received from the disaster prevention personnel H2 in the district corresponding to the obstacle warning information (S304), the support server 1 waits for a “response completed” response from the disaster prevention personnel H2 in charge of the relevant district. (No in S307). This is based on the premise that the person in charge of disaster prevention in the district always responds, but if there is any risk ahead of the person in charge of disaster prevention in the district, in the sense of ensuring the safety of the person in charge of disaster prevention in the district, You may make it time-out in predetermined time and make another disaster prevention person express to the spot.

  When receiving a response of “completion of response” from the disaster prevention personnel in the relevant district, the support server 1 stores the information in the storage unit 1c in association with the obstacle warning information (S308). In other words, the response result input via the terminal possessed by the disaster prevention personnel in the corresponding district is stored in the storage unit 1c in association with the obstacle warning information. Then, the series of processes is terminated and the normal state is restored.

  When there is no reply from the disaster prevention personnel H2 in the district corresponding to the obstacle warning information, the support server 1 waits until a predetermined time elapses (No in S305), and when the predetermined time elapses (Yes in S305). Then, the fact that no action has been taken is associated with the obstacle warning information and stored in the storage unit 1c (S306), and a series of processing is terminated to return to the normal state. However, since there is no correction for obstacles as it is, countermeasures by fire prevention managers, security guards, etc. are required in the high risk time zone. In addition, when there is a grace time for handling instead of the high risk time zone, it is necessary to perform some kind of handling during that time.

  In addition, there may be a case where the disaster prevention person H2 in the relevant district is far away from the relevant district and returns “cannot handle”. Moreover, there may be a case where the disaster prevention person H2 in the corresponding district is absent. In preparation for such a case, it is desirable to appoint alternative personnel in advance. Then, it is desirable to have the terminal M, register it in the storage unit 1c of the support server 1, and notify the obstacle warning information and the response instruction instead of the disaster prevention person H2 who cannot respond (see FIG. Not shown). Such operation is appropriately determined.

  Next, with reference to FIG. 8, operation | movement of the disaster prevention support system regarding patrol guard is demonstrated.

  The patrol guard H1 (refer to FIG. 1) possesses the patrol guard terminal M1 (refer to FIG. 1), inputs that the patrol guard terminal M1 starts patrol when starting the patrol guard, and this is entered. The terminal M1 transmits a message to that effect to the support server 1 (S501).

  The support server 1 that has received the patrol start signal via the network N and the communication unit 1d refers to the storage unit 1c and checks whether or not there is caution information (S502). If there is caution information, the support server 1 generates a patrol route including a position with the caution information so that the patrolling security terminal M1 includes the position with the caution information so that the location with the caution information is focused. The traveling route is transmitted, and the traveling route is instructed to the patrol guard H1 (S503). If there is no caution information, the support server 1 instructs the patrol guard H1 on a normal patrol route registered in advance (S504).

  The patrol guard H1 performs patrol guard according to the instructed patrol route and checks whether there are any obstacles in the evacuation route (S505). When the obstacle X1 (see FIG. 1) is found on the evacuation route or when the suspected obstacle X1 (see FIG. 1) is found (discovered in S506), the patrol person H1 is a patrol terminal. The object X1 is photographed by the camera device Md provided in M1 and transmitted to the support server 1 (S507). At this time, the patrol terminal M1 transmits the position information based on the provided position detection unit Mc and the imaging time together with the image data.

  The support server 1 that has received the image data of the object X1 via the network N and the communication unit 1d stores this in the storage unit 1c as obstacle information. Then, as described above, the degree of obstacles is determined to generate obstacle warning information (see FIG. 5), and this is associated with the obstacle information and stored in the storage unit 1c, and notifications to persons concerned with disaster prevention are made. Perform (see FIG. 7).

In addition, when the patrol guard H1 does not find an obstacle or an obstacle-like object (no discovery in S506), the patrol route is instructed until the patrol is completed (No in S508), and seems to be an obstacle or an obstacle. If the tour ends without finding an object (Yes in S508), the end of the tour is input to the patrol guard terminal M1, and the tour ends (S509). At this time, the patrol guard terminal M1 transmits the end of patrol to the support server 1 (S510), and the support server 1 that has received this stores the patrol guard end in the storage unit 1c and ends the series of patrol guard operations. (Not shown).
[Embodiment 2]
The disaster prevention support system according to the present embodiment is substantially the same as that of the first embodiment, and the only difference is the determination means for determining the degree of obstacle due to an obstacle. That is, the determination unit of the first embodiment automatically determines the operation shown in FIG. 5 by using image processing or the like, whereas the determination unit of the present embodiment has a human operation as shown in FIG. The degree of failure is determined.

  The operation of the disaster prevention support system according to the present embodiment will be described by applying the operation described in FIG. 9 instead of the operation of the first embodiment described in FIG.

  When the obstacle sensor 6 detects the obstacle X2 (S101), the image data (S102) of the obstacle X2 included in the obstacle information sent from the corresponding monitoring camera 5 to the support server 1 or the patrol guard Obstacles detected by the support server 1 via the network N and the communication unit 1d by photographing the object X1 detected by the person H1 during the patrol guard with the camera device Md of the patrol guard terminal M1. The image data (S507) of the object X1 included in the object information is automatically displayed on the display unit 2 which is a display unit disposed in the disaster prevention center, for example, via the information processing unit 1b of the support server 1. (S210).

  And the disaster prevention person monitoring in the disaster prevention center sees the image projected on the display part 2, and determines whether it is an obstruction (S211).

  When it determines with the target object projected on the display part 2 not being an obstruction, a determination process is complete | finished without doing anything (No of S211).

  When it is determined that the object projected on the display unit 2 is an obstacle (Yes in S211), the disaster prevention personnel or the fire prevention manager monitoring at the disaster prevention center determines the degree of the obstacle, The determination result is input to the support server 1 via the operation unit K as input means (S212). Note that the determination criteria are based on the determination performed by image processing as shown in FIG. That is, the degree of inhibition of the obstacle that obstructs the closing of the automatic closing device or the obstacle that completely blocks the evacuation route is judged to be the largest, and the degree of inhibition is judged by the size of the obstacle that occupies the evacuation route. .

  The support server 1 to which the degree of obstacle is input stores the determination result in the storage unit 1c as the obstacle warning information in association with the image data.

Since other operations are the same as those in the first embodiment, description thereof is omitted.
[Embodiment 3]
The disaster prevention support systems described in Embodiments 1 and 2 can also be used as refuge difficulty information in evacuation guidance when a fire occurs.

  In the present embodiment, when a fire occurs, a fire signal from an automatic fire alarm facility is input to the information processing unit 1b via the signal receiving unit 1a of the support server 1, and the support server 1 that has received the fire signal is stored in the storage unit 1c. The latest information of the obstacle information stored in the terminal is transmitted to the terminal M possessed by the disaster prevention person via the communication unit 1d as the refuge difficulty information and notified.

  The evacuation difficulty information here does not mean that evacuation is impossible, but means information that is considered when selecting an evacuation route. However, if there is obstacle information or obstacle warning information for which patrol security is performed every day and attention information is stored as a result and no response is stored, the evacuation route that passes through the location is careful. It can be said that this is not a route that should be used whenever possible.

  In this way, an evacuation route that passes through a position where caution information for which no response result is stored is stored may be notified to the terminal M possessed by a disaster prevention person as a route to be avoided.
