Abstract: In order to solve problems of low labor efficiency, large labor intensity, low accuracy and poor real-time performance of traditional equipment spot inspection system, an equipment spot inspection system based on wireless communication was proposed. The system, which is designed by use of technologies of single-chip microcomputer, wireless communication and computer information management, has multi communication ways, including wireless radio frequency RF communication, GSM communication and internet communication. The system can on line inspect main parameters of field equipments such as vibration, temperature, pressure and so on, and can make an early warning according to environmental conditions. Meanwhile, the system has function of remote monitoring. The test result showed that the system has good stability and significantly improves operation management quality of equipment spot inspection system.
