Design Of Nanjing College Of Information Technology Digital Security System

In recent years, the campus security, harm against students, school rights cases have often occurred, the internal security management of university only by people defense is not enough; campus security has become a hot topic in a high degree of social concern. With the full application of information and digitization, digital security defense is fully developed and mature, especially the development of the digital security campus particularly rapidly. Based on the personnel identity information and behavior event as the core, digital security defense automatically monitor and control the movement of persons, goods flow, information interaction and emergency events, judgment and intelligence analyze on site conditions fatly the fusing the digital monitoring video, and automatically send alarm information to the network upper management. In the security system in a large number of technologies are used such as digital image processing, encoding and decoding, digital transmission and etc. Compared with the traditional security system, digital security system can fully meet the people’s growing demand for security system with higher system performance, clearer transmission image and higher anti-interference ability.Firstly, the digital security defense system theory is introduced in this thesis. Then, the structure of digital security defense system, design basis and principles are described. Based on analyzing the security requirement of the system of Nanjing College of Information Technology, the overall design is given in the college digital security defense system which including video monitoring system, intrusion alarm design ideas and design of monitoring point. Finally, the design of integrated management security defense system platform and the function description of the management platform are given. The design and engineering implementation of digital security system reflect new design ideas in new period university security with prevention first and evidence complementary, provide more reliable security for the establishment of a harmonious and peaceful campus.
