Description

Surveillance system with intruder erasure function and its control method {SUPERVISION SYSTEM HAVING INVADER CAPTURE FUNCTION AND METHOD THEREOF}

The present invention relates to a surveillance system, and more particularly, to a surveillance system for monitoring whether an intruder has occurred and to combat an intruder when an intruder enters, and a control method thereof.

In general, in case of monitoring whether an intruder enters a specific place, a CCD camera or CCTV is installed in the monitoring place, and the guards observe the video taken by the CCD camera or CCTV in a central control room away from the monitoring place to generate an intruder. Monitor whether or not.

In this way, when the security guard monitors whether an intruder is generated through the monitor, if the intruder intrudes into the monitoring place, the security guard moves to the monitoring place to combat the intruder.

However, in the past, security guards must always watch the monitor to monitor the occurrence of intruders, so the guard must always stay in place, thereby increasing the cost of system maintenance. In addition, when an intruder occurs while the guard is away, the guard cannot know whether or not the intrusion occurs, so there is a disadvantage in that the response due to the intruder is not made quickly.

In order to solve this drawback, even if the guards do not always observe the monitor, a system for informing the presence of intrusions by automatically calling the guards when an intruder has been developed.

However, this system also has a disadvantage in that it can not respond quickly to the intruder's intrusion operation as the security guard detects that the intruder invades the monitoring site and then takes time until the security guard arrives at the monitoring site. As a result, the damage of the intruder may be increased, thereby reducing the reliability of the surveillance system.

Therefore, an object of the present invention is to monitor whether or not an intruder enters, and to automatically invade an intruder when the intruder invades, thereby improving surveillance security performance.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a monitoring system having an intruder eradication function according to an embodiment of the present invention, and FIG. 2 is a flowchart of an operation of the monitoring system having an intruder eradication function according to an embodiment of the present invention.

As shown in FIG. 1, a surveillance system having an intruder erasure function according to an embodiment of the present invention includes a CCD camera 10, an object detecting unit 15, a data input unit 20, and a microphone 25. The microcontroller 30 connected to the output terminal thereof, the warning unit 35 connected to the output terminal of the microcontroller 30, the image display unit 40, the signal transmitting and receiving unit 45 and the intruder elimination unit 50, the memory 55 ) And the camera rotating part 60.

The CCD camera 10 is installed at a place to be monitored and photographs an intruder who invades the monitoring place to generate a corresponding video signal. Instead of the CCD camera 10, another imaging apparatus (CCTV, etc.) capable of generating an image signal can be used.

The object detector 15 detects a moving object that invades the monitoring place and outputs a corresponding object detection signal. In the embodiment of the present invention, the object detection unit 15 detects a change in temperature due to a body temperature of an intruder and detects a corresponding object. It consists of a plurality of infrared sensors for outputting signals, but is not limited thereto. The object detecting unit 15 is not installed in only one part of the place to be monitored, but is installed in various parts to efficiently detect an intruder who invades the monitoring place.

The data input unit 20 inputs a telephone number of a security guard for notifying whether an intruder is generated or not, and inputs data for setting various control values required for the monitoring operation, and may be made of a keyboard or the like.

The microcontroller 30 determines whether an intruder is generated according to an image signal and an object detection signal input from the CCD camera 10 and the object detecting unit 15, and when the intruder enters the monitoring site, a warning operation and an intruder eradication are performed. Output a plurality of control signals for.

The warning unit 35 includes a speaker 351 for outputting a warning message indicating to go out when a person intrudes under the control of the microcontroller 30, and a warning display unit 352 for outputting a warning sound or a warning light. Is done. The warning display unit 352 may be formed of a buzzer or a lamp.

The image display unit 40 displays an image corresponding to the image signal photographed by the CCD camera 10 under the control of the microcontroller 30, and may be installed at a monitoring location or installed at a central system.

The signal transmission / reception unit 45 dials the security guard's telephone number set by the data input unit 20 according to the control signal output from the microcontroller 30, and transmits the signal to the security guard's terminal 47 and the signal through the communication network 46. Voice signals, text signals). The communication network 46 may be a telephone network or a wireless communication network. Accordingly, the signal transceiver 45 may transmit or transmit a signal to be transmitted by wire processing or wireless processing under the control of the microcontroller 30.

The intruder elimination unit 50 eradicates the intruder who has invaded the monitoring site under the control of the microcontroller 30. In the embodiment of the present invention, the intruder elimination unit is composed of a gas gun that fires a certain amount of anesthesia gas at the monitoring site to combat the intruder. However, the present invention is not limited thereto, and a variety of devices (eg, net guns) may be used to prevent and invade an intruder's action.

The camera rotating unit 60 includes a motor for rotating the CCD camera 10 at a predetermined angle (for example, about 180 °) under the control of the microcontroller 30.

The microphone 25 is installed in the monitoring place, and converts the voice of the intruder or various sounds generated by the invasion operation into an electrical signal and outputs it to the microcontroller 30.

The memory 55 stores the image photographed by the CCD camera 10 in units of one frame.

In the embodiment of the present invention, the CCD camera 10, the object detecting unit 15, the microphone 25, the warning unit 35 and the intruder elimination unit 50 are installed in the monitoring place, the microcontroller 30 ), The video display unit 40 is installed in a central control room away from the monitoring place.

In addition, the monitoring system sound having an intruder erasure function according to an embodiment of the present invention can be driven according to the AC power applied from the outside, and may further include an auxiliary battery to be able to drive in the event of a power failure.

The operation of the monitoring system having the intruder erasure function according to the embodiment of the present invention having such a structure will be described.

When power is applied, the microcontroller 30 initializes all the devices, and then drives the camera rotating unit 60 to rotate the CCD camera 10 at a predetermined angle. Accordingly, the CCD camera 10 rotates to photograph the monitoring place, and at this time, the object detecting unit 15 detects a moving object in the monitoring place, that is, an intruder.

When the intruder enters the monitoring site, the object detector 15 detects a temperature change caused by the intruder's body temperature and outputs a corresponding object detection signal. Since the object detecting unit 15 is already known, a detailed description thereof will be omitted.

When the object detection signal is output from the object detection unit 15, the microcontroller 30 processes the image signal output from the CCD camera 10 according to an image recognition algorithm to determine whether an intruder is a human.

In more detail, even when a temperature change due to a change in air conditioner wind or a temperature change by an animal such as a cat or a dog is detected, an object detection signal may be output from the object detecting unit 15, so that the microcontroller 30 Determines whether the intruder is a human based on the image signal photographed by the CCD camera 10.

In addition, the microcontroller 30 may determine that an intruder is generated when a signal corresponding to a specific sound detection of a monitoring place is output from the microphone 25, and in this case, the animal may be invaded. Likewise, it is determined whether the intruder is a human based on the video signal.

The microcontroller 30 processes the video signal output from the CCD camera 10 in accordance with an image recognition processing algorithm such as contour processing, feature extraction, and the like to determine whether the captured intruder is a person (S110 to S120). Since the image recognition processing algorithm is a known technology, detailed description thereof will be omitted.

When the intruder who enters the monitoring place is a person, the microcontroller 30 drives the image display unit 40 to display the captured image (S130 to S140), and drives the signal transceiver 45 to drive the data input unit 20. Dial the phone number set by (S150). At the same time, the microcontroller 30 drives the warning unit 35 to output a warning message or the like to the intruder (S160).

The speaker 351 of the warning unit 35 outputs a warning message such as 'intruder go out' and at the same time, the warning display unit 352 sounds a warning sound or emits a warning light to warn the intruder to go out. .

As the warning operation is performed as described above, the signal transmission / reception unit 45 transmits a dial signal to the security guard's terminal 47 through the communication network 46, and the microcontroller 30 is connected to the security guard's terminal 47. The signal transmitting and receiving unit 45 transmits a message indicating that an intruder has occurred to the terminal 47 of the security guard. This message may be transmitted to the terminal 47 in the form of a voice signal or a text signal.

When the security guard receives a message indicating that an intruder has occurred through the terminal 47, the security guard can talk with the intruder who has invaded the monitoring site through the terminal 47. That is, when the security guard speaks a warning message or the like to the terminal 47, the corresponding signal is received and processed by the signal transmission / reception unit 45 through the communication network 46, and then the speaker 351 is controlled by the microcontroller 30. It is output as a warning message of a security guard sent through. When the intruder speaks a response message, the response message is processed as an electrical signal through the microphone 25 and then transmitted to the terminal 47 of the security guard through the signal transceiver 45 and the communication network 46. Therefore, even if the security guard is not in the central control room, etc., the intruder can be threatened to go out (S170 to S180).

When the intruder exits according to the warning message, the microcontroller 50 stops the driving of the warning unit 35 and ends the warning operation such as the warning message output (S190 to S200).

However, if the intruder still does not go out despite the warning message is output, the microcontroller 30 determines whether the set time has elapsed since the output of the warning message (S210). As described above, the warning message output operation is continuously performed (S220).

On the other hand, when the set time has elapsed, the microcontroller 30 combats the intruder so that the intruder can no longer perform illegal activities. In the embodiment of the present invention, if the intruder continues to perform illegal activities as described above, the microcontroller 30 drives the intruder elimination unit 50 to fire a certain amount of anesthetic gas toward the intruder (S230). ).

Thus, the anesthesia gas causes the intruder to lose his mind and prevent further illegal activities.

On the other hand, in addition to determining whether the set time has elapsed, it is also possible to determine whether the number of warning message outputs has exceeded the set number of times and perform an intruder eradication operation when the set number of times has been exceeded.

In the above embodiment, a warning operation is performed only when the chip particle is a human by the CCD camera 10 after detecting that an intruder is generated by the object detector 15, but the object detector 15 is not limited thereto. Even when it is detected that an intruder is generated by the warning operation may be made immediately.

That is, when a signal according to the intruder is output from the object detection unit 15, the microcontroller 30 immediately drives the warning unit 35 regardless of the signal output from the CCD camera 10 to perform the above-described warning operation. Perform and notify the occurrence of chipping to the security guard through the signal transmission and reception unit 45. In addition, even though the above-described warning operation continues for a predetermined time or continues for a predetermined number of times, when the signal according to the intruder detection is continuously output from the object detecting unit 15, the microcontroller 30 drives the intruder eradication unit 45. To defeat the intruders.

In addition, the image photographed by the CCD camera 10 may be transmitted to another system through a signal transceiver.

As described above, according to the embodiment of the present invention, it is possible to provide a monitoring system having an intruder eradication function that can not only effectively monitor a specific place but also stop illegal activities of an intruder.

In addition, by automatically eradicating the intruder, it is possible to prevent damage caused by illegal activities of the intruder.

In addition, as the warning operation is performed only when the intruder is a human, frequent or unnecessary warning operations can be prevented from occurring. Therefore, the monitoring efficiency is improved.

In addition, security personnel can easily know whether an intruder occurs from anywhere, thereby improving the reliability of the surveillance system.

This invention is capable of various modifications and implementations without departing from the scope of the following claims.
