With The Implementation Of Building Security System Information Technology Office Of Modern 5a Level

China’s enterprises are in rapid development stage, a variety of new building erected in recent years. In the past the intelligent building security system’s structure has been complicated, and very complicated in operation, it’s need to with the points table to switch the surveillance video, but cannot found the incidents and suspicious behavior timely, it has a bad evident in the linkage of video surveillance systems with alarm system and access control system. In signal transmission process, there is much interfere factors and tedious maintenance, so it has a great significance in exploring new information security system design for modern 5A class office building. This paper is divided into five levels analysis of security systems.First, the paper has a in-depth discussion and analysis in the early history of the development of security systems, concrete building methods, features and shortcomings exist in the system. Detailed analysis of the current situation and the lack of the subsystems of security systems, such as surveillance systems, access control system, alarm system and power supply system.Second, with the being implemented E-town’s technology center project, the paper select the most advanced network monitoring system, network access control systems and network alarm system for analysis, research in a reasonable manner to conducted system integration, via Ethernet protocol to the linkage of system, solve the problem of the real-time of security system and the complexity in construction and operation.Third, adding intelligent video analysis system in video surveillance systemto enhance the efficiency of the system, reducing the workload of security personnel.Analysis the power security system, combined with the design of the power supply system and the engine room, achieve safe and reliable power supply system and good equipment operating environment.Fourth, it has a secondary development of the IVMS-8700 intelligent integration platform, integrate the sub-system of security system, use the same platform to achieve integration and linkage, solve the problem of interfaces and protocols’ incompatibilities of video surveillance systems, access control systems and alarm system.Fifth, make a conclusion and analysis the design deficiencies of information technology in security system and the future direction of the design in intelligentsecurity information system.Currently the system has successfully applied in E-town’s Center project. Test results show that the system can achieve integration and linkage response in the subsystem of security system, and system configuration is simple and easy operation,the performance is stable, data is safe and reliable, it has achieve the desired design goals.
