It is a conceptual diagram which shows one Embodiment of the emergency condition grasping | ascertainment system by this invention. It is a functional block diagram explaining one embodiment same as the above.

  Hereinafter, an embodiment of an emergency situation grasping system according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a conceptual configuration of this embodiment, and FIG. 2 shows a functional configuration of this embodiment. 1 and 2, an imaging apparatus (hereinafter described as a camera) 11 is installed in a monitoring target area. The monitored area is a place where there is little traffic, for example, an alley, a building, an underpass, a school road, a park, a dangerous place without street lights, and the like. A plurality of cameras 11 are installed at these locations to be monitored at intervals. In the example of FIG. 1, it is attached to the utility pole 12 arrange | positioned at predetermined intervals along a street. As shown in FIG. 2, the camera 11 is equipped with a swivel base and a projector, and is posture-controlled toward the object to be imaged by an imaging control device 15 controlled by the data processing device 14 on the site 13 side. Accordingly, the projector is turned on to image the object. The video signal picked up by the camera 11 is sent to a data processing device 19 of an information center 18 provided at a remote place through a transmission line 16 constituting an infrastructure network.

  As shown in FIG. 1, the information center 18 is configured to be able to input an emergency alert signal from a mobile phone 21 existing in the monitored area. Here, the emergency alert signal transmitted from the mobile phone 21 is received by the receiving antenna 22 of the base station of the telephone company (mobile carrier), transmitted from the transmitting antenna 23, and received by the receiving unit 18a of the information center 18. The The data processing device 19 of the information center 18 includes an imaging device position storage unit 25 in which position information of a plurality of cameras 11 provided on the site 13 side is stored.

  When the data processing device 19 of the information center 18 receives the emergency alert signal from the mobile carrier, the data processing device 19 specifies the position of the mobile phone 21 that issued the emergency alert signal based on the received signal from the mobile carrier. Then, a plurality of cameras 11 that can image the specified position are selected from the data stored in the imaging device position storage means 25. Images picked up by these selected cameras 11 are recorded in the recording device 26. The captured image of the camera 11 closest to the position of the mobile phone 21 is displayed on the monitor. At this time, camera control such as turning of the camera and zooming operation is performed as necessary to capture an optimal image. In addition, an image captured by another selected camera 11 can be arbitrarily selected and switched and displayed on the monitor.

  Here, the reason why a plurality of cameras 11 capable of imaging the position of the mobile phone 21 that issued the emergency alert signal is selected is as follows. In general, a captured image of the camera 11 closest to the position of the mobile phone 21 that has issued the emergency alert signal (which is also an emergency occurrence site) can capture the situation of the emergency occurrence site in detail. However, depending on the situation of the emergency occurrence site, there may be a blind spot with respect to the imaging range of the nearest camera. In such a case, even if the distance is a little far, an image of another camera that reliably captures the emergency occurrence site from another angle may be more effective in grasping the situation of the emergency occurrence site. Therefore, a plurality of cameras 11 capable of capturing an emergency occurrence site are selected, and their images can be arbitrarily switched. With this configuration, it is possible to accurately grasp the situation of the emergency occurrence site with the most appropriate video. In addition, by recording images taken from different angles, it is possible to accurately analyze the situation of the emergency occurrence site.

  In the above description, the occurrence of an emergency event is transmitted to the information center by means of an emergency alert signal from the mobile phone 21, but the present invention is not limited to this. For example, in order to warn the vicinity of the occurrence of an emergency situation on the site 13 side, an alarm ringing device (hereinafter, described as a siren) 28 using a siren or a bell may be provided together with the camera 11. In this case, an emergency call button 29 for sounding the siren 28 is provided near the siren 28. Therefore, when the emergency call button 29 is operated, the siren 28 nearby is sounded, and an emergency call signal is generated by operating the emergency call button 29, and this emergency call signal is transmitted to the information center 18 through the transmission line 16. The data processing device 19 is configured to be input.

  When the emergency notification signal is input, the data processing device 19 of the information center 18 specifies the camera 11 corresponding to the installation position of the operated emergency notification button 29 from the imaging device position storage unit 25. That is, if the installation position of the emergency call button 29 is registered in advance, the camera 11 corresponding to this installation position can be specified. At the same time, the other camera 11 capable of imaging the installation position of the operated emergency call button 29 (which is also an emergency occurrence site) is specified. The captured images of the plurality of specified cameras 11 are recorded in the recording device 26, and can be arbitrarily selected and switched and displayed on the monitor.

  Even when configured in this way, a plurality of cameras 11 capable of imaging the occurrence site are selected, and by arbitrarily switching these images, the situation of the occurrence site can be accurately grasped with the most appropriate video. . In addition, by recording images taken from different angles, it is possible to accurately analyze the situation at the site of occurrence.

  When the emergency alert signal from the mobile phone 21 is input to the information center 18, the siren 28 is located closest to the mobile phone 21 that has issued the emergency alert signal by the operation of the monitor who has confirmed this emergency situation. What is to be performed may be caused to ring from the information center 18 side through the transmission line 16.

  Further, on the site 13 side, a speaker 31 may be provided near the installation position of the camera 11 so that the instruction content from the information center 18 can be output as a voice. That is, in the information center 18, when an emergency alert signal from the mobile phone 21 from the site 13 side or an emergency notification signal from the emergency notification button 29 is input, an image captured by the camera 11 corresponding to the monitor is displayed on the monitor. To check the situation of the occurrence site. In this case, if a speaker 31 is provided near the installation location of the camera 11 at the site 13 (also near the site where the emergency occurred), the supervisor who grasps the situation at the site can respond via the transmission line 16. The speaker 31 can output an instruction corresponding to the situation of the emergency occurrence site.

  This instruction is given by the monitoring staff of the information center 18 while monitoring the emergency occurrence site with the monitor, so that an accurate instruction can be given. For example, when an emergency alert signal is input that a passerby has had a heart attack, the supervisor instructs the reporter where to store the AED (automated external defibrillator) and how to use it. be able to.

  In addition, an interphone 32 may be provided near the installation position of the camera 11 on the site 13 side so as to be able to interact with a monitor of the information center 18. Also in this case, a specific instruction can be given from the information center 18 side to the emergency reporter by operating the emergency call button 29 using the intercom 32.

  In the above-described configuration, when an emergency alert signal is transmitted from the mobile phone 21 existing at the site 13 in the event of an emergency situation, the mobile carrier receiving antenna 22 receives the signal and the transmitting antenna 23 sends it to the remote information center 18. An alarm is issued. At this time, the mobile carrier detects the emergency command position from the received radio wave intensity of the emergency alert signal, and sends the location information of the mobile phone 21 to the information center 18 together with the emergency alert signal.

  When the information center 18 receives the emergency alert signal, the information center 18 identifies an emergency occurrence site based on the location information of the mobile phone that has transmitted the emergency alert signal. Then, the data processing device 19 searches the imaging device position storage means 25 and selects a plurality of cameras 11 capable of imaging the specified position. Images picked up by these selected cameras 11 are sent to the information center 18 through the transmission line 16 of the network, and are recorded (recorded) in the recording device 26, respectively. At this time, camera control such as turning of the camera and zooming operation is performed as necessary to capture an optimal image. Moreover, the captured image of the camera 11 that is closest to the position of the mobile phone 21 that has transmitted the emergency alert signal (which is also the site where the emergency occurred) is displayed on the monitor.

  Usually, the captured image of the camera 11 closest to the emergency occurrence site captures the situation in detail, but depending on the situation, the situation in the site may not be sufficiently captured due to entering the blind spot. . Therefore, the selected image picked up by the other camera 11 is selected and displayed on the monitor. In other words, by capturing an emergency occurrence site from another angle with another camera, it is possible to accurately grasp the site situation. In addition, since the captured images of the plurality of cameras are recorded in the recording device 26, the situation analysis after the fact can be appropriately performed.

  At this time, the monitor of the information center 18 can sound the siren 28 installed at the site 13 as necessary to notify that an emergency has occurred around it.

  If the caller of the emergency situation is not carrying a mobile phone, pressing the emergency call button 29 installed with the siren 28 causes the siren 28 to ring and indicates that an emergency has occurred. The information center 18 can be notified through 16. Also in this case, a plurality of cameras 11 capable of capturing an emergency occurrence site are selected from the position information registered in advance of the pressed emergency call button 29, and these captured images are recorded (recorded) in the recording device 26, respectively. And the captured image can be displayed on the monitor.

  The monitor of the information center 18 gives an instruction to the site through the speaker 31 installed at the site 13 while confirming the video displayed on the monitor. In addition, when the whistleblower can be contacted, the situation at the site can be confirmed by mutual communication using the intercom 32.

  Based on these confirmation results, emergency contact is made with the public facilities (the police station 35, the fire station 36, the school 37, etc.). The public facility which has received this notification is notified of the exact location from the information center 18 and rushes to the site.

  The system of the present invention can also be applied to emergency notifications of crimes (traffic violence, molesters, etc.) in transportation such as trains by simplifying the system components. In the case of a train, an emergency call is sent to the conductor, so you can check the situation by rushing to the vehicle on site.

  Currently, surveillance cameras installed in the city have captured a wide area, so it was impossible to grasp the situation occurring in a specific place. Since the positional relationship can be accurately grasped, optimal real-time video can be taken by automatic control turning and zooming. Further, since the notification is from a predetermined base, it is possible to specify the exact location where the emergency has occurred. By identifying the location of occurrence accurately, it is possible to speed up the initial response to the site.

  Furthermore, since the danger warning can be issued by the siren 28, the speaker 31, and the like, and the intercom 32 can be used for mutual communication, these infrastructure facilities can be effectively utilized even in the event of a disaster.
