I. Project Background
With the rapid development of China's national economy, the improvement of people's living standards and informatization, people's requirements for living environment and safety requirements are also increasing. However, the frequent occurrence of violence in the campus and the security situation of the school are unremarkable. As a result, the burglar alarm bus system provided by Zhongan Consumer IoT Sensor (Shenzhen) Co., Ltd. was provided. It can provide a safe and reliable burglar alarm management platform. It uses today's most advanced security technology to provide communication with superior units and departments. The entrance and exit of the alarm communication between the society, realize the informationization of school burglar alarm, and provide better security services for school office.
1 ) The main entrances and exits, important departments, and important protected areas of the entire building are subject to alarm monitoring to effectively prevent the occurrence of various cases, and detectors are installed in each department.
2) Multi-level intrusion prevention for the main entrances and exits, important departments, and important protected areas of the entire building, and recording of various types of alarm events, so as to provide an effective means for building security prevention.
3) The construction of an integrated security and protection platform is conducive to daily operations and management, thereby providing a more operable management platform for government security prevention. The powerful intelligent linkage mechanism makes full use of the maximum performance of the security system, thereby providing a stronger "technical defense" support for the security prevention of government buildings.
In the design of the school anti-theft alarm system, from the perspective of strictness of prevention, it is divided into two parts, one is the elevator room, the main entrance and exit; the other is the financial, archival, and leadership offices and other important departments, which are protected by infrared microwave double-detection detectors Illegal intrusion. The other part is to block certain key office departments in the building, such as archives, etc. All detectors are centrally controlled by the security center, so the school anti-theft alarm system needs to use a large-scale bus alarm control system.
C9000 is the management monitoring software of LHB9000, a bus-type host of China Security Corporation. It synchronizes the status of the host in real time, displays the current event information, and can conduct operations such as arming and disarming, parameter configuration, etc. on the host through a more convenient interface than the keyboard. It provides zone structure, user information, and event information viewing and management. Real-time display of electronic map, voice alarm and other functions. Perform corresponding event recording and alarm display on the alarm events transmitted by the alarm control host, and perform voice alarms and report printing at the same time, and can output on the map of the user's location or zone map. Management software can automatically record system events, operation records, registration information and other operations that occur in the system. Security system management software can remotely perform operations such as arming / disarming, bypassing; query historical record conditions; perform data backup, data recovery and other operations on historical data.
The system topology is as follows:
Fourth, system advantages
1. Easy to expand
One alarm host can be expanded to a maximum of 248 programmable zones, and 31248 zones can be expanded through the keyboard zone, so you can connect up to 31248 pairs of infrared radiation alarm probes. Since the alarm probes can be connected in series, theoretically, the front-end alarm probe The number can be expanded infinitely. In addition, as long as the alarm probe is hung on the bus, it does not need to be directly connected to the host.
The operation content that the direct alarm management personnel need to grasp is very simple, only 2 ~ 3 commands can be used, basically all personnel can operate it, and the alarm response generated by this alarm system can be output through a high-power alarm, which can effectively stop crime Illegal invasion of molecules, and can give effective reminders to security and management personnel. The management personnel can also divide the defense area into several areas and number them. Each area can be individually armed and disarmed through the bypass design, which makes the management appear flexible and convenient.
3.Simple construction, stable and reliable
The construction difficulty of the bus-type alarm system is relatively low, mainly reflected in the simple pipe wiring, and because fewer bus cables are used, the system works more stable and the error rate is low. Wider coverage than ordinary alarm systems. Although the cost of the equipment of the bus-type alarm system is relatively high, when the system is divided into many areas and the prevention area is large, the superiority of the bus is reflected, and the cost will be much lower than that of the ordinary alarm system. cost of.
The maintenance of the bus-type alarm system is simpler. Although the bus-type alarm system is very different from the ordinary alarm system, their implementation meaning is the same, both to enhance the security of the area and prevent the intrusion of criminals. If the defense zone of this system fails, it will automatically leave the system without affecting other defense zones, and there will be a zone fault prompt in the system for easy maintenance and replacement.
