Description

 The present invention not only remotely monitors a monitoring target person such as an intruder in the monitoring target area by detecting infrared rays emitted from the human body using infrared detection means such as a thermal camera, but also responds to the monitoring target person. The present invention relates to a commander identification device and a command support system capable of accurately commanding a commanded person such as a security guard from a remote location.

As is well known, infrared detection means such as a thermal camera is a device for detecting and imaging infrared rays generated by the temperature of a target, and has a high perceptual imaging capability in bad environments such as bad weather. Therefore, in recent years, it is widely used in the security field (see, for example, Patent Document 1 below). Such a security thermal camera is particularly adjusted to detect infrared rays generated by the body temperature of a person.
Japanese Patent Laid-Open No. 10-308939

  By the way, the body temperature of a person is approximately 37 degrees, and there are very few individual differences. Therefore, naturally, the infrared intensity generated by the body temperature has very little individual difference, and the person imaged by the thermal camera looks almost the same except for the size of the body. For this reason, in addition to remotely monitoring surveillance subjects such as intruders in the surveillance target area, conductors such as guards who respond to the surveillance subject while the conductor waiting in the remote area sees the infrared image When conducting remote command, it is difficult for the conductor to distinguish the monitored person and the conductor from the infrared image in a situation where the monitored person and the conductor are intermingled. It becomes.

 The present invention has been made in view of the above-described circumstances. In the case where the monitoring target area is remotely monitored using the infrared detection means and the commanded person is remotely commanded, the commanded person existing in the monitoring target area is provided. It is an object of the present invention to provide a commanded person identification device and a command support system capable of discriminating a person other than a commanded person and conducting an accurate command.

 In order to solve the above-mentioned problem, in the present invention, as a first solving means related to a conductor identification device, an infrared generator that is attached to the body of the conductor and generates infrared rays, and the conductor And a timing control means for controlling the infrared generation timing by controlling the infrared generation means.

 Further, as a second solving means relating to the conductor identification device, in the first solving means, the timing control means is the generation timing of the infrared rays individually assigned in advance as the identification information of the conductor. The infrared generation means is controlled so that the infrared rays are generated according to the above.

 Further, in the present invention, as means for solving the command support system, the above-described commandee identification device mounted on the body of the commanded person who is active in the monitoring target area, and the infrared ray that detects infrared rays in the monitoring target area The detector is installed in a standby place of the conductor who conducts the commanded person, and for imaging the infrared generation state in the monitoring target area based on the infrared detection result by the infrared detector Data processing means for generating image data, and an image that is installed in the waiting area of the conductor and that represents the generation status of infrared rays in the monitoring target area based on the image data generated by the data processing means And image display means for displaying.

  According to the present invention, the subject identification device that generates infrared rays at a predetermined timing is attached to the commanded person, thereby remotely monitoring the monitored area using the infrared detection means and remotely commanding the commanded person. In this case, the conductor can distinguish between the conductor and the person other than the conductor from the image displayed on the image display means (that is, the infrared image), and grasps the positional relationship and behavior of the two to accurately identify the conductor. It is possible to take command.

 Hereinafter, with reference to the drawings, an embodiment of a person identification apparatus and a command support system according to the present invention will be described. As the command support system according to the present embodiment, for example, an intruder (monitored person) in a monitoring target area set in an airport or a station premises is remotely monitored, and a guard who is a commanded person responding to the intruder is used. An example of a security system for remotely commanding a member will be described. That is, the commanded person identification device according to the present embodiment is attached to the above-mentioned guard, and enables discrimination between a guard and a person other than the guard (that is, an intruder) in the monitoring target area.

  FIG. 1 is a schematic configuration diagram of a security system according to the present embodiment. In FIG. 1, reference numerals 10 </ b> A and 10 </ b> B are guards (conductors) who guard the monitoring target area 100. Reference numerals 11A, 12A, 11B, and 12B denote infrared markers (infrared generation means), reference numerals 13A and 13B denote timing control devices (timing control means), and reference numerals 14A and 14B denote mounting belts. Reference numeral 20 stands by at a standby place 200 installed in a remote location of the monitoring target area 100, and is a conductor who remotely commands the guards 10A and 10B from the standby place 200. Reference numeral 30 denotes an intruder who has entered the monitoring target area 100. Reference numeral 40 denotes an infrared camera (infrared detection means), reference numeral 50 denotes a PC (Personal Computer: data processing means), and reference numeral 60 denotes a monitor (image display means). The infrared markers 11A and 12A and the timing control device 13A mounted on the guard 10A constitute a conductor identification device according to the present invention. Similarly, the infrared markers 11B and 12B and the timing control device 13B attached to the guard 10B constitute a conductor identification device.

  The infrared marker 11A is mounted on the top of the guard 10A and is electrically connected to the timing control device 13A via a signal cable or the like. A predetermined occurrence occurs under the control of the timing control device 13A. Generate infrared rays at the timing. The infrared marker 12A is mounted on the upper arm of the right arm of the guard 10A and is electrically connected to the timing control device 13A via a signal cable or the like. Infrared rays are generated at the generation timing (same timing as the infrared marker 11A).

  The timing control device 13A is mounted on the abdomen of the guard 10A via the mounting belt 14A, drives a battery provided therein as a power source, and controls the infrared markers 11A and 12A to control infrared rays. Control the generation timing. In addition, in the internal memory of the timing control device 13A, the generation timing of infrared rays individually assigned as identification information of the guard 10A is set in advance, and the timing control device 13A is individually assigned to the guard 10A. The infrared markers 11A and 12A are controlled so that infrared rays are generated at the generation timing.

  The generation timing of the infrared rays in the infrared markers 11A and 12A described above can be defined, for example, at a timing according to the Morse code. For example, individual identification information “A” can be assigned to “•-” and “S” can be assigned to “. Note that the generation timing of infrared rays is not limited to the Morse signal, but may be specified at a timing in accordance with another encryption signal or a standard uniquely established in the present system.

The mounting belt 14A is a belt used for mounting the timing control device 13A to the body of the guard 10A, and a passive member that assists the identification of the guard 10A by sewing an infrared opaque material on the surface thereof. It is desirable to use a marker.
In addition, the mounting positions of the infrared markers 11A and 12A and the timing control device 13A in the guard 10A may be changed as appropriate, and the infrared marker 11A at the top of the head may be mounted on a hat or a helmet.

  The same applies to the infrared markers 11B and 12B, the timing control device 13B, and the mounting belt 14B attached to the guard 10B. That is, the infrared generation timing individually assigned as identification information of the guard 10B is set in advance in the internal memory of the timing controller 13B, and the timing controller 13B is individually assigned to the guard 10B. The infrared markers 11B and 12B are controlled so that infrared rays are generated at the occurrence timing. In addition, although FIG. 1 illustrates the case where two guards 10A and 10B are arranged in the monitoring target area 100, the same as the guards 10A and 10B even when a plurality of guards are arranged. Of course, it is equipped.

  The infrared camera 40 is installed in the vicinity of the monitoring target area 100, detects infrared rays generated in the monitoring target area 100, and the infrared detection result (specifically, the infrared intensity distribution in the monitoring target area 100). Is output to the PC 50. The infrared camera 40 and the PC 50 are electrically connected via a communication cable or the like. Or you may use the infrared camera 40 which has a function which transmits an infrared detection result to PC50 by radio | wireless.

  The PC 50 is a personal computer installed in the waiting place 200 of the conductor 20, and a CPU (Central Processing Unit) 50a and a storage device 50b such as a hard disk are provided therein. Based on the video signal input from the infrared camera 40 via the communication cable, the CPU 50 a generates image data for imaging the generation state of infrared rays in the monitoring target area 100 and outputs the image data to the monitor 60. To do. The storage device 50b is at least a guard who should command at least guard information (director information) representing a correspondence relationship between the guard who is the commandee and the generation timing of infrared rays individually assigned to the guard. Saved for the number of people. That is, the storage device 50b stores at least guard information regarding the guard 10A and the guard 10B.

  When the CPU 50a generates image data for imaging the generation status of infrared rays in the monitoring target area 100, the infrared generation timing in the monitoring target area 100 and the guard information stored in the storage device 50b. Based on the above, the individual identification of the security guard who is the source of infrared rays in the monitoring target area 100 is performed, and the individual identification result of the security guard is imaged together with the infrared generation status in the monitoring target area 100 Generate data. The monitor 60 is, for example, a liquid crystal display, and is installed in the standby place 200 of the conductor 20, and the generation status of infrared rays and the guards in the monitoring target area 100 based on the image data generated by the CPU 50 a in the PC 50. An image representing the individual identification result is displayed.

  In this embodiment, the case where the security guard information is stored in the storage device 50b in the PC 50 is exemplified, but the security guard information may be stored in an external storage device of the PC 50 or the like. Although not shown in FIG. 1, since the conductor 20 commands the remote guards 10A and 10B while looking at the display image on the monitor 60, the guards 10A and 10B can communicate with each other so that they can talk to each other. A voice communication device is mounted, and a voice communication device is also provided at the standby place 200.

  Next, the operation of the security system according to the present embodiment configured as described above will be described with reference to FIGS. In addition, during the security of the monitoring target area 100, the infrared markers 11A, 12A, 11B, and 12B attached to the security guards 10A and 10B are individually assigned to the security guards 10A and 10B by the control of the timing control devices 13A and 13B, respectively. Infrared rays are generated at the generation timing assigned to.

  FIG. 2 is a flowchart showing the operation of the security system according to the present embodiment. As shown in FIG. 2, when the monitoring target area 100 is photographed by the infrared camera 40, infrared rays generated in the monitoring target area 100 are detected, and the infrared detection result (that is, the intensity of infrared rays in the monitoring target area 100). A video signal representing the distribution is output to the PC 50 (step S1).

  The CPU 50a of the PC 50 obtains digital data representing an infrared detection result (infrared intensity distribution) in the monitoring target region 100 by digitally converting the video signal input from the infrared camera 40 (step S2). And CPU50a extracts the person who exists in the monitoring object area | region 100 based on the digital data showing an infrared detection result (step S3). Specifically, in the region where the person exists in the infrared intensity distribution, the infrared intensity near 37 degrees, which is the body temperature of the human body, appears in a human shape, so that the 37 degrees collected in such a human shape. A region where the infrared intensity in the vicinity appears can be extracted as a person existing in the monitoring target region 100.

  Subsequently, the CPU 50a confirms whether or not the infrared rays emitted from the infrared marker are blinking for each person extracted as described above, thereby determining whether the person is a security guard or a person other than the security guard (that is, the intruder 30). ) Is identified (step S4). That is, in this step S4, when the CPU 50a confirms that the person blinks infrared rays emitted from the infrared marker, the CPU 50a identifies the person as a guard (step S5). At this time, the CPU 50a has not identified whether the person is the guard 10A or 10B. On the other hand, in step S4, when the CPU 50a cannot confirm blinking of infrared rays emitted from the infrared marker to the person, the CPU 50a identifies the person as a person other than the guard, that is, the intruder 30 (step S6).

  Then, the CPU 50a measures the blinking timing of the infrared marker for each person identified as a security guard, that is, the generation timing of infrared rays emitted from the infrared marker (step S7), the measurement result of the generation timing of the infrared rays, and the storage device 50b. The individual identification of the security guard is performed based on the security guard information stored in (step S8). Specifically, for example, as shown in FIG. 3, the infrared generation timing of “pattern A” is assigned to the security guard 10A, and the infrared generation timing of “pattern B” is assigned to the security guard 10B. When the security guard information shown is stored in the storage device 50b, the CPU 50a identifies the security guard whose infrared ray generation timing measurement result is “pattern A” as the security guard 10A, and the infrared ray generation timing measurement result is “ The guard of “pattern B” is identified as the guard 10B.

  Then, the CPU 50a visualizes the generation status of infrared rays in the monitoring target area 100 (that is, the presence status of the person in the monitoring target area 100 extracted in step S3) and the individual identification result of the security guard in step S8. Image data is generated and output to the monitor 60 (step S9). The monitor 60 displays an image representing the presence status of the person in the monitoring target area 100 and the individual identification result of the security guard based on the image data generated by the CPU 50a (step S10). FIG. 4 is an example of an image that is displayed on the monitor 60 and represents the presence status of the person in the monitoring target area 100 and the individual identification result of the security guard. As shown in FIG. 4, the person whose positions corresponding to the infrared markers 11A, 12A, 11B, and 12B are blinking is a guard, and the guards 10A and 10B are in accordance with the blinking timing (infrared generation timing). And the individual identification result are displayed. In addition, as shown in FIG. 4, you may make it display the result identified with the intruder with respect to persons other than a guard, ie, the intruder 30. FIG.

  By repeating steps S1 to S10 as described above, the monitor 60 displays in real time an image representing the presence status of the person in the monitoring target area 100 and the individual identification result of the security guard. The conductor 20 can grasp not only the presence or absence of the intruder 30 in the monitoring target area 100 but also the positional relationship and actions of the intruder 30 and the guards 10A and 10B by viewing the screen of the monitor 60. Even in a situation where the intruder 30 and the guards 10A and 10B cross each other, the guards 10A and 10B can be commanded accurately. That is, according to the security system according to the present embodiment, when the monitoring target area 100 is remotely monitored using the infrared camera 40 and the guard is remotely commanded, the security guard and the intruder existing in the monitoring target area 100 are used. It is possible to identify and accurately conduct.

This is particularly effective for the conductor 20 to quickly grasp the positional relationship and actions of these persons when there are a large number of guards and intruders present in the monitoring target area 100. On the other hand, when the number of persons existing in the monitoring target area 100 is small, the video signal output from the infrared camera 40 is converted into image data as it is and displayed on the monitor 60, and the infrared marker displayed on the monitor 60 is displayed. Based on the flashing status, the conductor 20 may be identified as a security guard or an intruder, and the security guard may be identified individually.

It is possible to provide a configuration in which an operation key that can be manually controlled is provided, and predetermined information is notified to the conductor 20 by the generation timing of infrared rays by the guard 10A operating the operation key. As a result, even if the voice communication device or the like cannot communicate with the conductor 20, information can be provided from the guard 10A to the conductor 20.

(3) In order to prevent the infrared markers 11A, 12A, the timing control device 13A and the mounting belt 14A from being abused over the hands of outsiders, the timing control device 13A is provided with a security key insertion portion, When an attachment / detachment detection switch is provided on the buckle portion of the attachment belt 14A, and the attachment belt 14A is removed after the attachment belt 14A is attached once and the security key is removed from the timing control device 13A, the internal circuit of the timing control device 13A determines The mode may be shifted to a mode in which the control of the infrared markers 11A and 12A is prohibited, and the mode is not canceled until the security key is inserted again.
