JP 2006-2011147 A

  However, when information is transmitted using radio waves as in the prior art described above, since the location of the transmission source cannot be specified from the transmitted radio waves themselves, there are many devices that detect the occurrence of disasters. There was a problem that it was difficult to install.

  For example, when a device that detects the occurrence of a fire and notifies by radio waves is installed in many facilities, even if a fire department etc. receives a notification from that device, the received radio wave itself is Since it is not possible to identify whether the notification is a notification, there is a possibility that a prompt action cannot be taken.

  If the correspondence between the identification number of the device and the installation location is registered in the database in advance and the identification number is included in the information transmitted by the device, the notification source device can be specified at the notification destination. The more devices that detect the occurrence of a disaster, the more man-hours required for database maintenance.

  The present invention has been made to solve the above-described problems caused by the prior art, and even when a large number of disaster detection means are installed, the occurrence location of the disaster can be accurately determined without increasing the maintenance man-hours. The objective is to provide a disaster observation system and disaster analysis program that can be identified.

  According to this aspect, the disaster detection means transmits information about the detected disaster to the sky using light rays, and determines the location of the disaster based on the image data taken from the sky. Even when a large number of disaster detection means are installed, it is possible to accurately specify the disaster occurrence position without requiring man-hours such as centralized management of identification numbers and positions of each disaster detection means.

  Further, the disaster analysis program disclosed in the present application is obtained in one aspect by capturing, in the sky, a signal transmitted by the disaster detection means that detects the disaster using the two types of light beams having different wavelengths simultaneously.

Even when a large number of detection means are installed, the disaster occurrence position can be accurately specified without requiring man-hours such as centralized management of identification numbers and positions of the disaster detection means.

  In addition, the above-mentioned problem can be solved by applying any combination of the constituent elements, expressions, or constituent elements of the disaster observation system and disaster analysis program to methods, apparatuses, systems, computer programs, recording media, data structures, and the like. It is effective to do.

  According to one aspect of the disaster observation system and the disaster analysis program disclosed in the present application, even when a large number of disaster detection means are installed, the occurrence location of the disaster can be accurately identified without increasing the maintenance man-hours. There is an effect.

  Exemplary embodiments of a disaster observation system and a disaster analysis program according to the present invention will be described below in detail with reference to the accompanying drawings.

  First, the overall configuration of the disaster observation system according to the present embodiment will be described. FIG. 1 is a diagram illustrating the overall configuration of the disaster observation system according to the present embodiment. As shown in the figure, the disaster observation system according to this embodiment includes a plurality of disaster detection devices 100 installed in a building 11, a power pole 12, etc., an airship 20 equipped with a disaster observation device 200 described later, and a communication satellite. 30 and a disaster countermeasure center 40 in which a disaster analysis device 400 described later is installed.

  The disaster detection device 100 detects the occurrence of a disaster on the ground, and transmits a signal corresponding to the detection result to the sky using two types of light beams having different wavelengths. By using two types of light beams having different wavelengths, the light source can be distinguished from other light sources such as aviation obstacle lights, and signals can be easily detected under various conditions. For example, if visible light and infrared light are used, signal detection is facilitated by infrared light during the day and visible light at night.

  The airship 20 is dispatched to a disaster area when a disaster such as an earthquake occurs. Recent airships are capable of flying at a speed of about 130km / h due to performance improvements, and if it is only necessary to arrive in the disaster area within 3 hours, it will cover the whole of Japan with about 5 airships. Can do. When the airship 20 arrives at the affected area, the airship 20 stops at an altitude of several hundred meters to several thousand meters for a long time, and observes the situation on the ground.

  The disaster observation device 200 mounted on the airship 20 uses an imaging device to photograph the signal transmitted by the disaster detection device 100 together with the terrain and structures in the observation area 1 and generate image data. The disaster observation apparatus 200 transmits the captured image data to the disaster countermeasure center 40 via the communication satellite 30.

  The disaster analysis device 400 of the disaster countermeasure center 40 analyzes the position and type of the signal included in the transmitted image data, and generates disaster data indicating where and what disaster has occurred based on the analysis result. To do. For example, the disaster data is obtained by adding a symbol indicating the type of the detected signal to the position where the signal is detected in the image data. The image data transmitted from the disaster observation device 200 includes the topography and structures seen from above, so that it is possible to obtain disaster data that can easily grasp the location and situation of the disaster even by adding symbols. It is possible to take effective measures.

  As described above, the disaster observation system according to the present embodiment grasps the disaster occurrence position and the situation based on the signals transmitted from the disaster detection apparatus 100 to the sky using two types of light beams having different wavelengths. According to this method, since the position of the disaster detection device 100 that detected the disaster is recorded in the image data taken from the sky, it is easy to locate the disaster occurrence place even if a large number of disaster detection devices 100 are installed. Can be identified.

  Next, the disaster detection apparatus 100 shown in FIG. 1 will be described in detail. In the following description, the same parts are denoted by the same reference numerals.

  FIG. 2A is a perspective view illustrating an appearance of the disaster detection apparatus 100. As shown in the figure, the side wall and the bottom surface of the disaster detection apparatus 100 are made of a refractory material 101 in order to prevent damage due to heat in the event of a fire. The upper surface of the disaster detection apparatus 100 is made of a transparent tempered glass 102 formed into a dome shape. By forming the tempered glass 102 into a dome shape, it is possible to minimize refraction of light rays irradiated to the sky even when the disaster detection device 100 is tilted to some extent, and to prevent shielding by falling objects. it can.

  A water intrusion port 103 is provided below the side wall of the disaster detection apparatus 100, and the water detection sensor 111c inside the disaster detection apparatus 100 detects water that has entered from the water intrusion when a flood occurs. The disaster detection apparatus 100 has a waterproof structure so that circuits and mechanisms other than the water detection sensor 111c are not submerged even when water enters from the water intrusion port 103.

  Of the side walls of the disaster detection apparatus 100, a conductive wire 104 through which a weak current flows is embedded in a side wall in contact with a building or the like. When a building or the like cracks due to an earthquake or the like and the conductor 104 is disconnected along with the crack, the disconnection sensor 111e inside the disaster detection device 100 detects the disconnection.

  FIG. 2B is a transparent diagram illustrating the inside of the disaster detection apparatus 100. As shown in the figure, a light emitting unit 120 is provided inside the disaster detection apparatus 100. In FIG. 2B, illustrations other than the light emitting unit 120 are omitted.

  The light emitting unit 120 is an apparatus for irradiating two types of light beams having different wavelengths toward the sky via the tempered glass 102. The light emitting unit 120 includes a light source 121 that emits a light beam having a certain wavelength, a light source 122 that emits a light beam having a wavelength different from the light source, and even when the disaster detection apparatus 100 is tilted with a tilt of a building or the like. And a movable part 123 for changing the direction of the light emitting part 120 so that the light is emitted.

  In addition, in order for the disaster detection apparatus 100 to detect water increase, it is necessary to install the disaster detection apparatus 100 at a position of about 1 m to 2 m above the ground. When the disaster detection apparatus 100 is installed at this position, when the building to be installed is tilted due to an earthquake or the like, the building itself becomes a shielding object, and the disaster detection apparatus 100 may not be able to transmit a signal toward the sky. There is. This problem can be solved by installing the disaster detection apparatus 100 on two different surfaces of the building. For example, if the disaster detection device 100 is installed and placed on the east and west sides of a building, the disaster detection device 100 installed on the east surface can transmit a signal to the sky even if the building is tilted to the west.

  FIG. 3 is a block diagram illustrating a functional configuration of the disaster detection apparatus 100. As shown in the figure, the disaster detection apparatus 100 includes an inclination sensor 111a, a temperature sensor 111b, a water detection sensor 111c, a power failure sensor 111d, a disconnection sensor 111e, a pulse length determination unit 112, and a pulse length storage unit. 113, a pulse generation unit 114, an attitude control unit 115, a rechargeable battery 116, and a light emitting unit 120.

  The tilt sensor 111a detects the tilt. The inclination sensor 111a can detect the inclination of the building due to an earthquake or the like. The temperature sensor 111b detects the temperature. An increase in temperature due to a fire can be detected by the temperature sensor 111b. The water detection sensor 111c detects the presence of water. The water detection sensor 111c can detect an increase in the water level due to water increase. The power failure sensor 111d detects the stop of power supply to the disaster detection apparatus 100. The occurrence of a power failure can be detected by the power failure sensor 111d. The disconnection sensor 111e detects breakage of the conducting wire 104. Breakage of the building can be detected by the disconnection sensor 111e.

  The various sensors described above are examples, and the disaster detection apparatus 100 does not have to include all of these sensors, and may include sensors different from these sensors.

  The pulse length determination unit 112 determines what signal the light emitting unit 120 transmits based on the detection results of the inclination sensor 111a, the temperature sensor 111b, the water detection sensor 111c, the power failure sensor 111d, and the disconnection sensor 111e. Specifically, the light emitting unit 120 is configured to simultaneously transmit a pulse signal of some length using two types of light beams having different wavelengths, and the pulse length determining unit 112 includes a tilt sensor 111a and the like. The pulse length is determined based on the detection result.

  The pulse length storage unit 113 stores setting data for the pulse length determination unit 112 to determine the pulse length. FIG. 4 is a diagram illustrating an example of setting data stored in the pulse length storage unit 113. As shown in the figure, the pulse length storage unit 113 defines a pulse length for each sensor when a predetermined signal is detected by various sensors.

  When the setting data stored in the pulse length storage unit 113 is as shown in FIG. 4, the pulse length determination unit 112 sets the pulse length when the disconnection sensor 111e detects the disconnection of the conducting wire 104. When it is determined as 1 second and the power failure is detected by the power failure sensor 111d, the pulse length is determined as 2 seconds. If the water level sensor 111c detects a rise in the water level, the pulse length is determined as 4 seconds. If the temperature sensor 111b detects a temperature exceeding the threshold value, the pulse length is determined as 8 seconds. When the inclination exceeding the threshold is detected by the inclination sensor 111a, the pulse length is determined to be 16 seconds.

  In addition, when a situation indicating the occurrence of a disaster is detected simultaneously by a plurality of sensors, the pulse length determination unit 112 sets the pulse length corresponding to each detection result as the pulse length. For example, when the setting data stored in the pulse length storage unit 113 is as in the example shown in FIG. 4, a temperature exceeding the threshold is detected by the temperature sensor 111b, and at the same time, an inclination exceeding the threshold is detected by the inclination sensor 111a. If detected, the pulse length is determined to be 24 seconds, which is the sum of 8 seconds and 16 seconds. In the example shown in FIG. 4, since the pulse length is set to a multiplier of 2, it is not unclear which sensor corresponds to the total pulse length.

  FIG. 5A is a diagram illustrating an example of a pulse signal transmitted by the light emitting unit 120. As shown in the figure, the light emitting unit 120 periodically transmits a pulse signal having a length determined by the pulse length determining unit 112. In the example shown in the figure, the light emitting unit 120 transmits a pulse signal every 60 seconds. The value of 60 seconds is determined so as to be larger than the pulse length of 31 seconds when the detection results of all sensors are reflected in the setting data example shown in FIG. . The example in FIG. 5A is an example in which a temperature exceeding a threshold is continuously detected by the temperature sensor 111b, and a signal having a pulse length of 8 seconds is transmitted.

  FIG. 5-2 is a diagram illustrating an example of a pulse signal when a plurality of situations are detected. The example shown in the figure is an example in the case where the temperature exceeding the threshold is continuously detected by the temperature sensor 111b, and at the same time, the inclination exceeding the threshold is continuously detected by the inclination sensor 111a. A signal having a pulse length of 24 seconds, which is the total of seconds, is transmitted.

  In the above description, one pulse length is set for each sensor type, but the pulse length may be set according to the magnitude of the detection value of the sensor. For example, the pulse length may be set differently when the temperature detected by the temperature sensor 111b is 40 to 60 ° C. and when the temperature is 60 ° C. or higher.

  Returning to FIG. 3, the pulse generation unit 114 generates a pulse signal having the pulse length determined by the pulse length determination unit 112 and supplies the pulse signal to the light emitting unit 120. The attitude control unit 115 controls the movable unit 123 of the light emitting unit 120 so that the light emitted from the light emitting unit 120 is directed upward. The rechargeable battery 116 supplies power to each unit when power supply from the outside stops. The light emitting unit 120 simultaneously emits two types of light beams (for example, visible light and infrared light) having different wavelengths from the light source 121 and the light source 122 in accordance with the pulse signal supplied from the pulse generation unit 114.

  Next, the disaster observation apparatus 200 mounted on the airship 20 will be described in detail. FIG. 6 is a block diagram illustrating a functional configuration of the disaster observation apparatus 200. As shown in the figure, the disaster observation apparatus 200 includes an imaging unit 201, a GPS (Global Positioning System) 202, an observation data storage unit 203, and an observation data transmission unit 204.

  The imaging unit 201 captures a signal transmitted by the disaster detection apparatus 100 together with the terrain and the structure in the observation area 1 using an imaging element or the like, and generates image data. The imaging unit 201 may be configured to record the signal transmitted from the light source 121 and the signal transmitted from the light source 122 in different image data, or both signals having different wavelengths in the same image data. May be recorded.

  The GPS 202 acquires the current position of the disaster observation apparatus 200. The observation data storage unit 203 stores the image data generated by the imaging unit 201, the current position acquired by the GPS 202, and the current time in association with each other as observation data. The observation data transmission unit 204 transmits the observation data stored in the observation data storage unit 203 to the disaster countermeasure center 40 via the communication satellite 30.

  Next, the disaster analysis apparatus 400 installed in the disaster countermeasure center 40 will be described in detail. FIG. 7 is a block diagram illustrating a functional configuration of the disaster analysis apparatus 400. As shown in the figure, the disaster analysis apparatus 400 includes an observation data acquisition unit 401, a control unit 410, and a storage unit 420 that stores various data. The observation data acquisition unit 401 acquires observation data transmitted from the disaster observation apparatus 200 via the communication satellite 30 and stores the observation data in the storage unit 420 as observation data 421.

  The control unit 410 is a control unit that controls the entire disaster analysis apparatus 400, and includes an observation data correction unit 411, a light source detection unit 412, a disaster type analysis unit 413, and a disaster information generation unit 414.

  The observation data correction unit 411 corrects image data included in the observation data 421 acquired by the observation data acquisition unit 401 and stored in the storage unit 420. Even when the airship 20 is stationary in the sky, the airship 20 is shaken or swung by the influence of the airflow. Due to this influence, each image data photographed by the disaster observation apparatus 200 is slightly shifted. The observation data correction unit 411 corrects this shift so that the same object is located at the same pixel in any image data. This correction can be realized by applying, for example, a camera shake correction technique used in a video camera or the like. This correction can also be performed in the disaster observation apparatus 200.

  The light source detection unit 412 detects a light source corresponding to the disaster observation apparatus 200 from the image data corrected by the observation data correction unit 411. Specifically, the light source detection unit 412, when light of two types of wavelengths emitted by the disaster observation apparatus 200 is detected from the same or neighboring pixels, the light source corresponding to the disaster observation apparatus 200 Detect as. It should be noted that the two types of wavelengths of light have different easiness to be detected depending on time zones, weather conditions, and the like. Therefore, when the light source detection unit 412 detects one of the two wavelengths of light in the image data, the light source detection unit 412 temporarily changes the determination level so that the light of the other wavelength is easily detected. Examine the pixel. In this way, even under conditions where it is difficult to detect one light source, it is possible to accurately detect light sources of two types of wavelengths using the other light source as a clue.

  The disaster type analysis unit 413 analyzes which type of disaster the light source detected by the light source detection unit 412 indicates. Specifically, the disaster type analysis unit 413 checks how long light emission has continued for each light source detected by the light source detection unit 412, and the duration is stored in the storage unit 420. The type of disaster is determined by collating with the existing pulse length data 422. The contents of the pulse length data 422 are the same as the setting data shown in FIG. When the content of the pulse length data 422 is the same as the setting data shown in FIG. 4, the disaster type analysis unit 413 fires the disaster detection device 100 at the position of the light source if the duration of light emission is 8 seconds. If the duration of light emission is 24 seconds, it is determined that the disaster detection apparatus 100 detects the occurrence of a fire and the inclination of a building or the like at the position of the light source.

  The disaster information generation unit 414 generates disaster data 423 indicating what kind of disaster is occurring at which location based on the analysis result of the disaster type analysis unit 413, and stores this in the storage unit 420. An example of the disaster data 423 is shown in FIG. The data shown in the figure includes a symbol corresponding to the disaster type determined by the disaster type analysis unit 413 at the position of the light source detected by the light source detection unit 412 in the image data transmitted from the disaster observation apparatus 200. It is added. Since the image data includes the landforms and structures on the ground, any kind of disaster can occur anywhere just by adding a symbol corresponding to the type of disaster to the position of the light source in the image data. The data useful for planning quick and appropriate measures can be obtained.

  In addition, the position information of the disaster observation apparatus 200 included in the observation data 421 is used to convert the position of the light source detected by the light source detection unit 412 into a latitude / longitude and an address, and the latitude / longitude and address and the disaster type analysis. The disaster data 423 can be recorded in association with the disaster type determined by the unit 413.

  Next, the operation of the disaster observation system according to the present embodiment will be described. FIG. 9 is a flowchart showing the operation of the disaster observation system according to the present embodiment. As shown in the figure, in the disaster detection apparatus 100, the pulse length determination unit 112 confirms the output of various sensors such as the inclination sensor 111a (step S101), and refers to the pulse length storage unit 113 to determine the pulse length. Determine (step S102). Then, the attitude control unit 115 corrects the direction of the light emitting unit 120 (step S103), and the light source 121 and the light source 122 of the light emitting unit 120 are light beams having respective wavelengths with the pulse length determined by the pulse length determining unit 112. Are simultaneously irradiated toward the sky (step S104). The disaster detection apparatus 100 repeatedly executes steps S101 to S104.

  When the airship 20 arrives above the disaster area, in the disaster observation apparatus 200, the imaging unit 201 captures the ground (step S201), the GPS 202 acquires the current position (step S202), and the observation data storage unit 203. The image data, the current position, and the current time are associated and stored as observation data (step S203). If a predetermined time has elapsed since the previous transmission (Yes at Step S204), the observation data transmission unit 204 transmits untransmitted observation data to the disaster countermeasure center 40 via the communication satellite 30 (Step S205). The disaster observation apparatus 200 repeatedly executes Steps S201 to S205 during the disaster observation process.

  Further, in the disaster analysis device 400 of the disaster countermeasure center 40, the observation data acquisition unit 401 acquires the observation data transmitted from the disaster observation device 200 (step S301), and stores it as the observation data 421 in the storage unit 420. (Step S302). Then, the observation data correction unit 411 corrects the observation data (step S303), the light source detection unit 412 detects the light source (step S304), and the disaster type analysis unit 413 identifies the type of disaster occurring at the position of the light source. Is analyzed (step S305). Then, the disaster information generation unit 414 generates disaster data 423 (step S306) and stores it in the storage unit 420 (step S307). The disaster analysis apparatus 400 repeatedly executes steps S301 to S307 during the execution of the disaster analysis process.

  Note that the configurations of the disaster detection device 100, the disaster observation device 200, and the disaster analysis device 400 can be variously changed without departing from the gist of the present invention. For example, a function equivalent to that of the disaster analysis apparatus 400 can be realized by mounting the function of the control unit 410 of the disaster analysis apparatus 400 as software and executing the function by a computer. An example of a computer that executes the disaster analysis program 1071 in which the function of the control unit 410 is implemented as software is shown below.

  FIG. 10 is a functional block diagram showing a computer 1000 that executes the disaster analysis program 1071. The computer 1000 includes a CPU (Central Processing Unit) 1010 that executes various arithmetic processes, an input device 1020 that receives input of data from a user, a monitor 1030 that displays various information, and a medium that reads a program from a recording medium. A bus 1080 includes a reading device 1040, a network interface device 1050 that exchanges data with other computers via a network, a RAM (Random Access Memory) 1060 that temporarily stores various information, and a hard disk device 1070. Connected and configured.

  The hard disk device 1070 includes a disaster analysis program 1071 having the same function as the control unit 410 shown in FIG. 7 and disaster analysis data 1072 corresponding to various data stored in the storage unit 420 shown in FIG. Is memorized. The disaster analysis data 1072 can be appropriately distributed and stored in another computer connected via a network.

  Then, the CPU 1010 reads out the disaster analysis program 1071 from the hard disk device 1070 and develops it in the RAM 1060, so that the disaster analysis program 1071 functions as the disaster analysis process 1061. Then, the disaster analysis process 1061 expands the information read from the disaster analysis data 1072 as appropriate to an area allocated to itself on the RAM 1060, and executes various data processing based on the expanded data.

  The disaster analysis program 1071 is not necessarily stored in the hard disk device 1070, and the computer 1000 may read and execute the program stored in a storage medium such as a CD-ROM. . The computer 1000 stores the program in another computer (or server) connected to the computer 1000 via a public line, the Internet, a LAN (Local Area Network), a WAN (Wide Area Network), or the like. You may make it read and run a program from these.

  As described above, in the present embodiment, the disaster detection device 100 transmits information related to the detected disaster to the sky using light rays, and this is based on image data taken from the sky by the disaster observation device 200. Since the disaster analysis device 400 determines the location where the disaster occurred, even when a large number of disaster detection devices 100 are installed, man-hours such as centralized management of the identification numbers and positions of the disaster detection devices 100 are required. The location of the disaster can be accurately identified.
