The community perimeter burglar alarm system is an important system for intelligent community management, including intrusion alarm system, patrol check-in system, access control system, closed-circuit television monitoring system, telephone alarm system, emergency help system...

       With the vigorous development of intelligence, people have put forward higher and higher requirements for living conditions. As an important part of the security system, the perimeter alarm system is getting more and more attention.

As one of the monitoring and information means of the security status of the work area, the perimeter defense system can be combined with the internal intercom system to echo the work intensity of the management personnel and improve the management quality and management efficiency. As a powerful auxiliary means of modernization, the perimeter defense system transmits the danger signals of various sites on the site to the main control center or the sub-control room. The duty management personnel can objectively monitor the monitoring areas without visiting the site. Uniform mobilization of the situation was found, saving a large number of patrol personnel and avoiding many human factors. In view of a management model, the perimeter prevention system is the most capable of this task, prompting residents to do their own work in a tight and orderly atmosphere, and can improve the reputation of the community, with a good environment, all-round security. Guarantee can create good social and economic benefits.

First, the system consists of

The community perimeter burglar alarm system is an important system for intelligent community management, including intrusion alarm system, patrol check-in system, access control system, closed-circuit television monitoring system, telephone alarm system and emergency help system.

1. Intrusion alarm system

The intrusion alarm system generally consists of a detector, an alarm controller, a linkage controller, an analog display screen, and a searchlight. For the general intrusion alarm system, the line type detector is often used, and the surface type detector can also be used according to the special requirements of the user. Line type detectors mostly use outdoor type dual/four-way active infrared detectors or laser detectors to form an anti-illegal crossing alarm system without leaving a dead angle. The system should adopt fuzzy control theory technology to effectively avoid the impact of detection alarms due to leaves, sundries, small birds, small animals, blizzards, etc., while ensuring that any large objects and people illegally overturn the fence or fence behavior immediately alarm. When the detector detects the intrusion signal, it sends an alarm to the community property management alarm center. The alarm center linkage controller opens the relevant area searchlight, sends an alarm siren, starts the video recorder, simulates the electronic screen to dynamically display the alarm area, and the alarm center monitors the computer to pop up the electronic map. And make an alarm record.

2. CCTV monitoring system

TV monitoring system is one of the important means of modern management, monitoring and control. It can directly view the actual situation of the monitored place through the camera and its auxiliary equipment (such as lens, pan/tilt, etc.), and can record the captured images with video and multimedia technology. It obtains a large amount of information, at a glance, and judges that the event is correct. It is an effective method for alarm review, dynamic monitoring, process control and information recording. The intelligent community requires the CCTV system to have a certain linkage control function. Therefore, the linkage interface of the intrusion prevention and other emergency situations should be provided on the console. When the linkage control alarm signal is received, the recorder is automatically activated to record the monitored area with the alarm. At the same time, the staff of the property management center can control the gimbal to track and monitor according to the alarm source and take corresponding measures.

3. Access control system

The access control system is an important channel for intelligent residential management. The door control system controls the access of personnel and controls the behavior of people in the building and related areas. Install access control devices such as card readers, fingerprint readers, PIN pads, etc. at the building entrance, elevator, etc. In order for a household to enter, they must have a card or enter the correct password, or both, or a special finger to be approved. The access control system can effectively manage the opening and closing of the door, ensuring that the authorized access personnel can freely enter and exit, and restrict unauthorized personnel from entering. At the same time, the entry and exit personnel code, access time, and entry number are registered and stored.

4, patrol check-in system

The patrol system is a means by which the manager examines whether the patrol arrives at the designated location at the specified time on a patrol route. The patrol system helps managers analyze the performance of patrol personnel, and managers can change patrol routes at any time through software to match the needs of different occasions and print out concise reports on computers and printers. The wireless patrol system consists of information buttons, patrol handheld recorders, downloaders, computers and their management software. Information buttons are installed at the scene, such as near the entrance of each residential building, in the canteen, underground parking lot entrance, garage, next to the main road, etc.; the patrol handheld recorder is carried by the patrol personnel on duty; the downloader is connected to the handheld record. A component for communicating information with a computer; it is placed in the room where the computer is located. No line connection is required between information buttons, between information buttons and computers, information buttons, and patrol handheld recorders. Therefore, the wireless patrol system has the characteristics of simple installation, no need for a dedicated computer, convenient expansion, and easy modification of the patrol route. The patrol system is set up for the completed residential community, and the wireless patrol system is easy to select. The cable patrol system is that the patrol personnel send a signal to the management computer at the specified time and place to indicate normality. If the signal is not sent to the management computer within the specified time, or not according to regulations The order of the signals appears and the system will consider the exception. In this way, problems or dangers of the patrol personnel will be quickly detected, thereby increasing the security of the community.

Second, the system design

 Now take a certain community as an example to introduce the design of the intelligent community perimeter burglar alarm system. The system pays attention to perimeter prevention, excludes dangers from the community, emphasizes overall prevention, takes the community as the center, and does not take the residents as the center for prevention; emphasizes three-dimensional prevention and combines various preventive measures. Infrared intrusion detection system and TV monitoring system are set up in the perimeter of the community. There are access control systems and TV monitoring at each entrance and exit. There are emergency help system, glass break detector and switch alarm in the house, at the main intersection of the community and the main public. The location has a telephone alarm system.

Infrared is a non-visible light source. It is difficult for an intruder to detect or evade. The defense boundary is very obvious, and the active infrared alarm has a long transmission distance. Considering the large range of the cell, the intrusion detection system uses an active infrared alarm. The system is installed on the fence, in the balcony of the house, in the windows and in areas where it is not convenient to reach the patrol.

The CCTV monitoring system installs cameras in important parts and places of the community, providing security personnel with electronic eyes to directly monitor the internal and external conditions of the cell in the control room, and can record in real time after receiving the alarm signal, and record the situation on the scene for replay afterwards. analysis. An all-round adjustable high-definition camera is installed at the main entrance of the community, and a good night vision effect can be ensured. At the entrance of the unit door and the garage door, there is a super wide-angle camera covering the entire entrance area. The camera in the garage is equipped with a monitor head to ensure timely alarm when someone breaks. During installation, we strive to achieve no dead angles and no waste of cameras, and equipped with long-term video recorders to record the signals transmitted back by the camera. For recent data, you can freely play back the pictures taken by any camera, and set the time, date, location, and camera number for easy analysis and processing.

 The access control system has a card reader at the entrance and exit. Residents of the community are required to enter and exit with IC card. IC card loss is immediately reported and the card information is cancelled. Visitors must register. Vehicle access and charging are also managed by IC card. Monthly cards are available for long-term users. Temporary IC cards are available for visiting vehicles. All IC cards are charged by the card reader and linked with the CCTV monitoring system for all incoming and outgoing personnel. The vehicle is automatically monitored.

A combined detector with a glass break detector and a magnetic switch is installed in the residence of the household. The product has an alarm relay (normally closed contact) and a strip of permanent magnet, regardless of the glass break alarm or the magnetic switch. As long as one party detects an intrusion, it triggers an alarm. There is also an emergency help system in the house, which uses the local area network to connect the household and the control center. When an emergency occurs, the control center can be connected with a single click, and the control center will give a sound and light prompt, and the computer will call up. An electronic map showing some basic information about the household, the on-duty staff can arrive in the shortest possible time.

The patrol sign-in system uses dynamic real-time online patrol technology to conduct cell patrol computer management. The patrol line of the community is based on the importance of the patrol points of the community, the actual route, the distance, etc., and is optimized by computer to form dozens of patrol routes, which are stored in the patrol management computer database, and the specific on-duty patrol route is The computer is randomly determined to avoid collusion between inside and outside.

Set up alarm calls at major intersections and major public places in the community. When the residents find the situation, pick up the phone and talk to the control center. The phone position can be displayed immediately on the electronic map of the control center, and linked with the CCTV monitoring system to adjust the position of the camera, display the image of the area, and make The recording device records the situation in the area.

Conclusion

With the rapid development of science and technology, the perimeter alarm technology has also developed rapidly. The intelligent community anti-theft alarm system is developing in a multi-functional direction. Combining modern detection technology, communication technology and computer network technology will be more effective. Ensure the safety of residents' lives and property, and exclude dangers from the community as much as possible.
