Description

Unmanned Security Alarm System {MANLESS PRESERVATION ALARM SYSTEM FOR PREVENTION OF INVASION}

The present invention relates to an unmanned security alert system, and more particularly, to an unmanned security alert system that detects a person who has invaded a specific space and alerts it to the outside or the inside.

A general unmanned security alert system detects an intruder (person or animal) who is not an insider, such as an insider, in a home, office or factory.

Such an unmanned security alarm system is a state-of-the-art system that secures the shortcomings of the simple system and improves the performance of the system after the development of a simple system that notifies the intrusion by detecting whether the door is opened or closed by a door detection device installed at the entrance. Vision alarm systems are being developed.

By the way, the vision alarm system is to determine the intrusion state from the outside in accordance with the detection of any object movement using the camera to inform the fact of the intrusion, there is a disadvantage that can not know the intrusion facts completely, if there are blind spots, In order to compensate for such a disadvantage, a plurality of cameras must be installed, but there is a problem in that installation cost and management cost are made.

In the case of a detection system using infrared rays, the detection range is narrower than that of the camera, so when the detection area is wide, the detection system needs to be installed more than the case of the camera.

The present invention has been made to solve the above problems, if there is an intruder in a certain specific space to detect the blind spot and three-dimensional space reliably to communicate to the outside and inside by communication or other alarm means Its purpose is to provide an unmanned security alert system.

In addition, the detection means is effective to include a camera for imaging the intruder, and an image recognition unit for analyzing and recognizing the movement from the image captured by the camera and output the result to the control means.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the present invention. 1 is a convex block diagram showing an unmanned security alert system according to the present invention.

Unmanned security alarm system according to the invention is installed in any particular space, such as a room, living room and kitchen and office of the home, as shown in Figure 1 to prevent intrusion into the specific space from intruders, A sensing unit (1) for detecting an intrinsic smell or sound generated from an intruder by at least one of smell and hearing, and amplifying a sensing signal of the sensing unit (1) with a gain of a predetermined size, and filtering the noise signal from it again Compares the detection signal processing unit 3 for shaping the waveform with the output signal from the detection signal processing unit 3 and a reference signal for security (a signal learned from a detection signal of an internal person repeated a plurality of times in the normal state). And a control unit 5 for judging and generating an alarm signal based on the result, and at least one of outdoor and indoor based on the alarm signal of the control unit 5. Toward at least any one of sight and sound and has communication lines alarm unit 7 for alarm. At this time, the sensing signal processing section 3 is composed of an amplifier section, a filter section and a waveform shaping section.

The sensing unit 1 is composed of a gas sensor 9, a microphone 11, and an infrared sensor 13 to operate individually, and the gas sensor 9 detects intrinsic odor gas generated from the intruder. Detects and outputs an odor signal, the microphone 11 converts the intrinsic sound generated from the intruder into an electrical sound signal, and outputs, and the infrared sensor 13 detects the temperature generated by the intruder to the electrical temperature It is converted to a signal and output.

The controller 5 repeatedly stores all data of the insider detected in the normal state, that is, the odor signal from the gas sensor 9, the sound signal from the microphone 11, and the temperature signal from the infrared sensor 13 a plurality of times. In addition, the learning algorithm classifies this by time zone and stores the learning data. Then, the learning data is compared with the current sensing signal input from the sensing unit 1 and determined, and an alarm signal is generated based on the determination. The learning algorithm, the learning data and the comparison and determination algorithm are stored in the control memory unit 15, and arithmetic operation of the data in the control memory unit 15 is performed by the microprocessor 17.

That is, in order to allow the system to distinguish between outsiders and insiders, the controller 5 analyzes the characteristics of the insider's sensed data, ie odor data, sound data, and temperature data in a steady state, and learns the final learning data ( Reference data signal), and in the unattended security state, compare and determine the learning data and the output signal of the detection signal processing unit 3, that is, the data signals for the sense of smell, hearing, and temperature of the current intruder. According to the result, an intrusion is generated as an alarm signal.

The alarm unit 7 generates a warning light 19 which visually informs the intrusion fact based on the alarm signal from the control unit 5, and generates an alarm sound that informs the intrusion fact as an alarm sound based on the alarm signal. The unit 21 and a transmission communication unit 23 for starting a communication to a place at a position remote from the intrusion fact via a communication line and informing the intrusion fact by voice based on the alarm signal. Here, the warning light 19 blinks until the system is reset with a predetermined brightness, and the warning sound is a sound having a specific frequency or the fact that the intrusion is actually, that is, "where there is an intrusion now". At this time, the voice of the communication unit 23 and the voice of the warning sound are stored in the control memory unit 15.

And, the communication unit is connected to the external command recognition unit 25 for applying an external remote command through the communication line dedicated to the reception to the control unit 5, the control unit 5 is the external command recognition unit An access blocking unit 31 for closing the entrance and exit of the specific space is connected by a command applied to (25). That is, the entrance blocking unit 31 opens and closes the door and locks the closed door.

In addition, in order to improve the reliability of the alarm signal of the control unit 5, a special sensing unit 1, that is, the image recognition unit 29 and the camera 27 are sequentially connected to the microprocessor 17. 27 captures the image of the intruder in real time, the image recognition unit 29 analyzes and recognizes the movement from the captured image and outputs the result to the control unit (5).

On the other hand, the microprocessor 17 is provided with an external expansion port 33 that can be connected to extend the elements and devices having a unique sensing function in addition to the function of the sensing unit (1).

The unmanned security alarm system as described above continuously learns the detection data of the insider in the normal state, and detects the learned data signal and the smell, sound, temperature and image of the intruder in the case of the crime state. It compares and judges the presence of intruders in the room and conducts emergency communication to the police station, security office, or crime prevention center, or alerts you to intrusions or alarms indoors or outdoors.

At this time, the emergency communication informs the intrusion fact by ARS voice, and the warning sound by voice and sound. In addition, when the exterior recognizes the intrusion from the outside and transmits the door closing command to the system by communication, the doorway of the room is closed to block the intruder's escape route.

The present invention is capable of three-dimensional three-dimensional detection by the smell, sound, temperature and image of the intruder, so it is possible to accurately recognize the intruder located in the blind area and to alarm through the communication, as well as indoor and outdoor, the entrance and exit quickly It can block intruders and block intruders, providing an unmanned security alarm system that can maximize the effectiveness of almost complete security crimes.
