Coal Ground Substation Monitoring System Of Wireless Network Design And Research

This paper surface coal mine substation parts of the country, the management level is still lower the status quo, put forward a TIs DSP chip TMS320LF2407 core processors for the smart terminals, the substation voltage, current, such as real-time monitoring, intelligent terminals and in the upper between use of safe, reliable wireless communication module communication.Achieved by radio remote data collection, monitoring and control, for the erection of special cable (or cable), the lease of telecommunications green, a low cost, efficient construction, operation and reliable, and easy to maintain. Wireless communications technology has been infiltrated to the industrial area, its simple installation and maintenance costs low is the most prominent advantages, in recent years, become a wireless network in the field of rapid industrial development of the hot spots of industrial automation products is the new growth point in the future .Paper discusses the various substation relay algorithm, algorithm tuning of the various settings, hardware protection devices, as well as control the on-chip chip TMS320LF2407 various hardware features, characteristics, intelligent terminal data acquisition and FIR filtering, FFT fast Fourier transform. of the equipment staff on a monitor.Intelligent terminal between the PC and wireless communications, real-time, and high reliability. Played an intelligent terminal system flexible, changeable, reliable communications features. The PC system using Visual Basic 6.0 Windows-based software development friendly man-machine interface. Use MSCOmm communication control programming for the operating personnel on the equipment once the supervision, fast display can be simple, convenient, reliable equipment on the first manual intervention. In addition, the system can also provide a safeguard, dialogue-friendly interface.Finally paper discusses hardware module test and debug the part of the process, the results of the basic performance indicators meet the requirement, and the test results are analyzed and summarized.
