Description

  The present invention relates to an intrusion monitoring apparatus that monitors an intrusion into a monitoring area, and more particularly to a technique that facilitates intrusion monitoring.

  In general, there are known intrusion monitoring apparatuses that are installed in facilities such as a nuclear power plant, an oil storage base, a water purification plant, and the like, take an image of a monitoring area in the facility, and detect illegal intruders in the facility. Such an intrusion monitoring apparatus will be described with reference to FIG. FIG. 5 is an overall configuration block diagram of the intrusion monitoring apparatus.

  In the monitoring area F, a fence W provided with a plurality of intrusion detection sensors t1 and t2 is installed, and a plurality of monitoring cameras c1 and c2 capable of pan / tilt operation for photographing the monitoring area F are installed. For example, the monitoring camera c1 captures the vicinity of the installation position of the intrusion detection sensor t1, and the surveillance camera c2 captures the vicinity of the installation position of the intrusion detection sensor t2.

  The intrusion detection sensors t1 and t2 and the monitoring cameras c1 and c2 are connected to a control unit B installed at a location away from the monitoring area F via a cable. Signals from the intrusion detection sensors t1 and t2 and the monitoring cameras c1 and c2 are given to the control unit B.

  The control unit B controls the display of the transmitted real-time image or video image on the monitors m1 and m2, and controls the camera operating devices P1 and P2 such as a touch panel for operating the pan / tilt operation of the monitoring cameras c1 and c2.

  The control unit B includes the recording unit R that continuously records the images of the monitoring cameras c1 and c2 before and after the intrusion, the intrusion detection sensors t1 and t2 in the monitoring region F, and the monitoring cameras c1 and c2. A graphic board G is provided that includes a lamp that indicates an installation position, and that indicates an intrusion detection sensor installation position and a corresponding monitoring camera installation position when an intrusion occurs. A speaker s is installed in the vicinity of the monitoring cameras c1 and c2.

  In such an intrusion monitoring apparatus, in normal times, that is, when no intrusion occurs, the operator looks at the monitor m1, m2 and the graphic board G to monitor the state of the monitoring area F, and if necessary. Then, the camera controllers P1 and P2 are operated to cause the surveillance cameras c1 and c2 to perform a pan / tilt operation, or an image is recorded in the recording unit R.

  Here, it is assumed that the human P enters the monitoring area F as an illegal intruder. The sensor t1 installed on the fence W detects this, and transmits a signal “intrusion” to the control unit B.

  The control unit B receives the “intrusion present” signal, operates the panning / tilting operation of the monitoring camera c1 so as to photograph the intrusion occurrence point, and the monitoring camera c1 supplies an image of the intrusion occurrence point to the monitor m1. Thereby, the operator can acquire the image of the intrusion occurrence and the monitoring camera c1 at the intrusion occurrence point.

  Then, the operator confirms the entry point on the graphic board G and records the image at this time in the recording unit R.

  Further, when the control unit B receives the “intrusion present” signal, the speaker transmits an operation signal to the speaker s, so that the speaker is inaccessible to the intruder P and immediately leaves. Please output a message such as “Please do” and prompt the user to leave the monitoring area F.

  Patent Document 1 describes such an intrusion monitoring apparatus.

JP 2003-44965 A

  By the way, in order to grasp the intrusion occurrence state, the operator must confirm the intrusion occurrence point and the image of the point by looking at both the monitor m1 and the graphic board G, which is complicated.

  Further, when the operator wants to check the image of the intrusion occurrence point later, the operator has to reproduce the image recorded in the recording unit R and view it on the monitor m1, which is complicated.

  In addition, for example, since power is not supplied to the intrusion detection sensors t1 and t2, the intrusion detection sensors t1 and t2 are not operating, and the detection sensitivity of the intrusion detection sensors t1 and t2 is low. Intrusion detection may not be performed.

  When the intrusion detection sensors t1 and t2 are infrared transmission sensors, the amount of light received by the infrared transmission sensor gradually decreases and the detection sensitivity decreases due to dense fog or rain, and the infrared transmission sensor outputs an alarm.

  The objective of this invention is providing the intrusion monitoring apparatus which can confirm the condition easily, when the intrusion to a monitoring area | region generate | occur | produces.

Note that there are a plurality of intrusion detection sensors, and in order to simplify the description, the installation position Ls of the intrusion detection sensor is displayed in a band shape.

  When the intrusion detection sensor t1 detects the intrusion of the person P, the graphic display unit 20 identifies and displays the intrusion occurrence point La (installation position of the intrusion detection sensor t1) by blinking, lighting or changing the display color. Furthermore, the graphic display unit 20 displays the image D of the intrusion occurrence point La, for example, at the lower right thereof.

  The operating state represents, for example, whether power is supplied to the intrusion detection sensors t1 and t2 and is operating. The detection sensitivity state represents the detection sensitivity of the intrusion detection sensor. As described above, when the intrusion detection sensor is an infrared transmission sensor, the intrusion detection sensor outputs an alarm when the detection sensitivity decreases due to dense fog or rain.
