Oil Well Working Status Inspection System

The SCADA system has become a grown-up and widely-used automation system mode of supervising and control through several decades of development and improvement since the introduction of 'SCADA system' in 1940's . the application of SCADA system varies with various environment and practical demand.This article deals with briefly the generation, growth and evolution and the concrete practice of SCADA system in present managing mode and social reformation by analyzing and studying conventional SCADA system.The article considers sufficiently the demand of the system cost, function and reliability imposed by practical condition and introduces in detail the of constitution, system betting and function of . This article devises at length the wireless data transmission which was not devised in traditional SCADA system and gives the technology demand, performance guideline and circuit parameter Of this module, which reduces the system cost greatly and set up condition for its spread.The article states in detail the work mode of main station device of receiving card, I/O card, driving circuit, the devising of sounding circuit using single- chip CPU and introduces the shell devising of RTU.Energy saving, avoiding being destroyed and installation handily, especially energy saving is characteristic of this system. The selection and use of encode and decode circuit simplify the system circuit and improve the reliability of wireless data transmission.At last, this article introduces the application and generation of this system and the great economic and social benefits of using this system according to statistical information.
