Research On Long-Distance Monitoring System Based On Web

Mainly from the angle of hardware and software architectures, long-distance monitoring system was discussed, then takes the Temperature and Smog Monitoring System on Tunnel Cable of Shanxi Aluminum Factory as background, how to realize it was deeply studied.Long-distance monitoring system was simply introduced in the first chapter, then the task of this paper was presented. In the second chapter, building network, field bus and intelligent instrument techniques of modern control and monitoring system were dwelled on. The building network scheme of long-distance control and monitoring system based on Web and the Temperature and Smog Monitoring System were both given. In chapter three, the software functions buildup of monitoring system was introduced. Then the software realization scheme of C/S , B/S mixed mode and its pertinent techniques were discussed and the Temperature and Smog Monitoring System was analyzed. In chapter four, utilizing the C/S and B/S mixed mode which based on ActiveX control with multithread, COM communication and socket communication techniques being integrated, the Temperature and Smog Monitoring System was realized. The sub-function modules of the application server, the Web server and the client were discussed in detail.The development and application of long-distance monitoring system were studied through universal mode and actual case, the feasibility of virtual COM applied in the industry monitoring system was demonstrated; Adopting C/S, B/S mixed mode,the software has strong data manipulation and affair processing abilities of C/S mode as well as the strong point of simple client of B/S mode; Using multi-thread technique in the design and realization of application server, the utilization rate of CPU was increased greatly, the information processing speed was quickened and the real-time degree of system was improved synchronously.
