Abstract:Valves are widely applied in many enterprises, its working condition is directly related to system security and economic effectiveness. Because the industrial characteristics of scattered field of the valve installation is not easy to wiring, using wireless transmission valve state parameter monitor broad prospects. This design of micro control unit adopts Si1000 is a RF chip integrated microprocessor and wireless transceiver module, and has advantage of low power consumption and long distance transmission, compared with most existing transceiver module working in 2.45GHz. In this paper it introduced a Si1000 based wireless status monitor hardware design of the valve, and develop the initialization of the MCU program monitors from standing between master station and communication program. The measured show that micro controller for Si1000 status monitor from the station, can meet the needs of the long-distance wireless communication with master station.
