The acoustic sensor 11 receives sound and converts the sound into an electrical signal, and transmits the electrical signal to the controller 60 through a network.

The air quality sensor 12 forms an abnormality detection signal and transmits the abnormality detection signal to the control unit 60 through the network when an abnormality occurs in the air quality due to toxic gas and volatile substances emitted from the terror suspect.

When the heat sensor 13 detects heat above a reference temperature when heat is generated by explosives and fires, the heat sensor 13 forms an abnormality detection signal and transmits the abnormality detection signal to the controller 60 through a network.

When the smoke detection sensor 14 detects smoke generated when an explosive is exploded, an smoke detection sensor 14 forms an abnormality detection signal and transmits it to the control unit 60 through a network.

The weight sensor 15 may be installed in, for example, a trash bin, and when the terrorist is thrown out and becomes heavier than the reference weight, the weight sensor 15 detects an abnormal weight to form an abnormality detection signal and transmits the abnormality detection signal to the controller 60 through a network.

By using the above-described multi-sensor 10, the one-dimensional monitoring by the photographing of the digital camera 20 can be compensated for more accurate monitoring.

The digital camera 20 photographs each section of urban railway history. In the present embodiment, the digital camera 20 is installed in a ticket gate, a trash can, a platform, a transfer passage, a staircase, and the like in a city railway history. In addition, the digital camera 20 may photograph each carriage of the railroad car and each zone of the platform divided into a plurality of zones.

The display unit 50 may be provided in plural so as to display image data photographed by a plurality of cameras, or the display unit 50 may be divided into a plurality of screens to simultaneously display data photographed by a plurality of cameras.

When the predetermined multi-sensor outputs the abnormal detection signal, the controller 60 recognizes the face of the terror suspect based on the image photographing the area where the multi-sensor 10 outputting the abnormal detection signal is installed. At this time, the control unit 60 receives images captured by the video server 30 in a plurality of areas including each passenger car of the railway vehicle in the city railway history. For example, the controller 60 sets the recognized user as a terror suspect when a user who roams in a platform or a trailing area in a city railroad history is recognized in an image photographed by the digital camera 20.

In addition, the controller 60 compares the recognized suspect's face with images taken by a plurality of different cameras to track the suspected terrorist, and forms a request message for removing the terrorist and transmits it to the history management office. Here, since a technology of recognizing a face of a person from image data photographed by the digital camera is a known technique, detailed description thereof will be omitted.

In addition, the controller 60 may use face matching technology when comparing a terror suspect face with images captured by a plurality of different cameras. The face matching technique may be implemented by using a method of tracking a subject by using features of a face in Korean Patent Registration No. 10-0407319 (announced Nov. 15, 2003). For example, the controller 60 may recognize a subject having a facial feature of a terror suspect among a plurality of subjects existing in images captured by a plurality of different cameras. According to another exemplary embodiment, a technique of tracking a subject by connecting a plurality of cameras may be used.

When the suspected terrorist is captured based on an image captured by a camera installed in the ticket gate (not shown), the controller 60 transmits a control signal to the ticket gate controller 40 to keep the ticket gate closed so that the terror suspect cannot pass. do. In addition, according to another exemplary embodiment, the controller 60 may generate an alarm when a terror suspect attempts to pass through a ticket gate based on the captured image, or may request an arrangement and arrest of a terror suspect in a security system located outside the history.

According to another embodiment, the controller 60 transmits the situation to the station office or the general management room through the wireless communication unit (not shown) when the terror suspect goes out of history. In addition, according to another embodiment, the control unit 60 detects that the suspect has committed an act of terrorism, such as dumping an object or intentionally losing an object, and trying to pass through a ticket gate. Broadcast through and do not allow passage through the turnstile.

The multi-sensor 10, the video server 30, and the controller 60 described above are connected to the digital camera 20 installed in a plurality of zones through a network (for example, an optical LAN). In addition, the video server 30, the display unit 50, and the controller 60 described above may be provided in a station room (not shown) of urban railway history.

2 illustrates a method for monitoring urban railway history terrorism according to an exemplary embodiment. As shown in FIG. 2, a plurality of digital video cameras 20 installed in a city railway history and a passenger car photograph each preset zone, and the captured image data correspond to the zone where the corresponding camera is installed in real time to the video server 30. ) And (S1).

The multi-sensor 10 installed in a plurality of preset zones in the city railway history detects at least one of air quality, heat, smoke, weight, and the like (S2).

When the multi-sensor 10 detects an abnormal state of air quality, heat, smoke, or weight in a predetermined area of a city railway or each passenger vehicle of the railroad car (S3), the controller 60 controls the multi-sensor 10. By receiving a predetermined abnormal detection signal from the image data of the area in which the abnormal state is detected is read by the video server 30, and the suspected terrorist based on the read image data (S4).

The controller 60 tracks the suspected terrorist by comparing the recognized terror suspect's face with images captured by a plurality of different cameras. That is, the control unit 60 recognizes the camera and the camera installation location for photographing the recognized terror suspect, tracks the terror suspect, and requests the terrorist to remove the terrorist object (S5). According to another exemplary embodiment, the controller 60 may perform an automatic tracking function of the digital camera by linking multiple cameras.

The controller 60 outputs a control signal to the ticket gate controller 40 when the suspected terrorist is located at the ticket gate, based on an image photographed by a camera installed in a predetermined section of a city railway and each passenger vehicle of the railroad car. Prevent terrorists from passing through the ticket gates (S5).

On the other hand, although not shown in the drawing, when a suspected terrorist boards a predetermined railroad car and moves to a city history where the railroad car will next stop, the control unit 60 performs wireless communication from a digital camera installed in each passenger car of the railroad car. Based on the transmitted video, it is determined which vehicle the recognized terror suspect is located in. Then, the control unit 60 transmits the checked passenger car information and the terror suspect information (for example, characteristic information of the terror suspect face, etc.) to the station or general management room of the city to be stopped next through the network. Accordingly, even if a terror suspect is moved on a railroad car, a terrorist suspect can be tracked in connection with the station or general management office of each railway station.

With such a configuration, the operator does not need to continuously monitor the camera by automatically monitoring each railway car of the city railway and railway cars using an image camera and a multi-sensor. In addition, by supplementing the limitations of the existing video surveillance system through a multi-sensor, the reliability of the image data is increased, and the maintenance cost due to malfunction of the camera can be reduced. In addition, it is possible to obtain more excellent terror surveillance effects by adding multi-sensors while maximizing the existing video surveillance system.

According to another embodiment, when an abnormality is found through the multi-sensor, a digital camera may be used to monitor the image as an image, and the multi-sensors may be used as a verification of the behavior of the person determined to be a terrorist.

According to another embodiment, closed-circuit television (CCTV) or digital cameras, which are generally visible, can be utilized, but night vision equipment such as infrared cameras can be used to identify the culprit during power outages or at night. In addition, it is possible to use a variety of devices, such as a device for detecting the body temperature of the human body using a thermal sensor.

According to the embodiments described above, by monitoring the terrorist acts of the urban railway using a camera and a multi-sensor, it is possible to promote the safety of urban rail users and to monitor the terrorism in real time.

Such a method and apparatus of the present invention have been described with reference to the embodiments shown in the drawings for ease of understanding, but this is merely exemplary, and those skilled in the art may have various modifications and equivalent embodiments therefrom. I understand that it is possible. Therefore, the true technical protection scope of the present invention will be defined by the appended claims.
