Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a nuclear power plant,
The present invention relates to an intrusion monitoring device installed in a facility such as a petroleum stockpiling base or a water purification plant to detect an illegal intruder or the like in the facility or the facility and issue a warning.

[0002]

2. Description of the Related Art With the increase in various important facilities and equipment as described above, there is an increasing demand for effective security systems against illegal intruders from the outside.

Conventionally, as an intrusion monitoring system, surveillance cameras are installed at several places to photograph the surveillance area, and an operator looks at the images and images transmitted from the surveillance camera to detect illegal intruders, or Laying a fence around,
A method has been adopted in which an electric current is passed through the fence and an intrusion detection sensor is installed so as to detect the presence or absence of intrusion when an intruder touches the fence.

[0004]

However, if the surveillance camera only monitors the area, the intruder can be easily found, but the action against the intruder and the action for the countermeasure are delayed, and the intrusion detection sensor is used. With this method, the intrusion detection and the action to the intruder are quick, but there is a problem that it is difficult to grasp the intrusion situation at the site.

The present invention is intended to solve the above problems, and to promptly detect an intrusion into the surveillance area, grasp the situation, and simultaneously perform an action to an intruder. The purpose is to

[0006]

The present invention which achieves the above objects is as follows. (1) In an intrusion monitoring device that detects an intrusion into a surveillance area, a surveillance camera that captures the surveillance area, an intrusion detection sensor installed in the surveillance area, and an intrusion detection signal obtained by the intrusion detection sensor An intrusion monitoring device, comprising: a control unit for directing a shooting direction of the surveillance camera to a point where the occurrence of the above-mentioned problem and outputting a voice message toward the point where the intrusion occurs. (2) The intrusion monitoring device according to (1), wherein the intrusion detection sensor is any one of a tension sensor, an infrared sensor, a vibration sensor, and the like. (3) The intrusion monitoring device according to (1), wherein the surveillance camera performs pan-tilt operation. (4) The intrusion monitoring device according to (1), wherein the voice message is transmitted from a speaker provided in the monitoring area.

DETAILED DESCRIPTION OF THE INVENTION An intruder monitoring device embodying the present invention will be described in detail below with reference to the drawings. FIG. 1 is an overall configuration block diagram of an intrusion monitoring device embodying the present invention.

A fence W equipped with an intrusion detection sensor t is installed in a field F, which is a monitoring area, and
A plurality of surveillance cameras c1 and c2 capable of pan-tilt operation for photographing the field F are installed.

As the intrusion detection sensor t, for example, a tension sensor, an infrared sensor, a vibration sensor or the like is selected and installed according to the application and the installation place. These intrusion detection sensor t and surveillance cameras c1 and c2 are connected via cables to a central instrument room C as a surveillance center, which is installed at a location apart from the field F. The intrusion detection sensor may be in any form other than the above tension sensor, infrared sensor, vibration sensor, etc. as long as the function is the same.
Any form and method may be adopted.

In the central instrument room C, the control unit B is supplied with signals from the intrusion detection sensor t and the monitoring cameras c1 and c2. The control unit B includes a camera control device, a switcher, a screen division device, and the like that configure this system, and monitors m1, m2 that display the transmitted real-time image, video or video image, and surveillance cameras c1, c.
It controls the camera operating devices p1 and p2 such as a touch panel for operating the pan / tilt operation and the like of FIG.

The control unit B has monitoring cameras c1 and c2.
A recording unit R for continuously recording the image of the intrusion before and after the occurrence of the intrusion, an intrusion detection sensor t in the monitoring area (field F), and a lamp indicating the positions of the monitoring cameras c1 and c2 are provided, and the intrusion detection sensor when the intrusion occurs. A graphic board G is provided which represents the position and the corresponding surveillance camera position.

In the present invention, in the field F,
Alternatively, the speaker s is installed near the surveillance cameras c1 and c2. The operation and the like will be described later. The speaker s may be configured to be built in the surveillance cameras c1 and c2.

In such a system, in a normal time, that is, when no intrusion occurs, the operator in the central instrument room C looks at the monitors m1 and m2 and the graphic board G to check the state of the field F. The monitoring cameras c1 and c2 are monitored by operating the camera operating devices p1 and p2 as necessary.
To perform a pan-tilt operation, or record an image or video in the recording unit R.

Here, it is assumed that a human P enters the field F as an illegal intruder. The sensor t installed on the fence W detects this and transmits a signal of "intrusion" to the control unit B of the central instrument room C.

The control unit B receives the signal of "intrusion" and pans and tilts the monitoring cameras c1 and c2 so as to photograph the place where the intrusion occurs, and the monitoring cameras c1 and c2.
Monitors images at the point of intrusion m1, m
Supply to 2. As a result, the operator can acquire the intrusion occurrence and the images and videos of the monitoring cameras c1 and c2 at the intrusion occurrence point.

Then, the operator uses the graphic board G
Check the location of the intrusion, and if necessary, use the camera operating device p
1 and p2, the pan / tilt operation of the surveillance cameras c1 and c2 is performed, or the image and video at this time are recorded in the recording unit R.

Further, in the present invention, the control unit B which has received the signal of "intrusion" transmits an operation signal to the speaker s, whereby the speaker notifies the intruder P of "intrusion". Messages such as "Do not enter here" and "Please leave immediately" are output by voice. Alternatively, a buzzer sound, a bell sound or the like is emitted from the speaker s to prompt the intruder P to leave the field F.

As described above, according to the present invention, in addition to the intrusion detection by the intrusion detection sensor and the video monitoring by the surveillance camera, when the intrusion actually occurs, the intruder can also be warned by voice.

[0019]

As described above, according to the intrusion monitoring device of the present invention, the following effects can be obtained. It is possible to quickly detect illegal intrusion into the surveillance area, at the same time as the detection direction of the surveillance camera is directed to the intrusion point, the situation of intrusion can be visually recognized from the image and video, Furthermore, by giving a voice message to the intruder, it is possible to simultaneously perform an action on the intruder.
