| Frequently occurrence vicious accidents lead to tremendous losses of people's lives and property. It is difficult to carry out real-time monitoring hazards which using traditional method of safety monitoring, and hidden dangers maybe buried. Therefore, it is a very urgent issue for safety supervision and administration departments that how to take full usage of modern network communications technology and computer technology to improve the efficiency of production safety supervision. The thesis is based on national scientific and technological support projects "Big cities major hazards monitoring and safety production integrated systems development", making a research and development of Networking-Tank Monitoring System which is short by N-TMS. N-TMS uses computer hardware and software technology, making remote monitoring and automation management for tanks, and achieve comprehensive security management for tank-owned enterprises.The thesis sums up the development of monitoring technology at home and abroad, uses theories and methods such as system engineering, safety engineering, information science and control science, according to the design ideas of independent modules and security features, raises the model of N-TMS, studies structural components and modules integration of monitoring system, as well as analyzing data structure design. Meanwhile, taking the comprehensive requirements of data transmission and environment situation, and using BP neural network, builds a green channel between areas of tanks and monitoring center. It is effectively guaranties the real-time and reliability of the monitoring system. In addition, making Industrial gas companies as research objects, initially authenticates the two main functions, green channel and leakage accident rapid assessment, and the results show that the monitoring system has a good practical. At last, from data acquisition and data processing optimize, forms performance optimization approach of N-TMS.
