Design Of Wireless Multi-parameter Sensor Testing Network Based On CC2430

With the development of science and technology, wireless sensor network (WSN) including sensor technology, information processing technology and network communication technology emerges. WSN is a new developing field in modern wireless communication. It is one of ad hoc network by a large number of sensor network nodes, which can realize data collection, quantification processing and transmission, and has a very wride development space and application prospect. The system is designed based on WSN (ZigBee stack) in this paper.Multi-parameter, including temperature, salinity, dissolved oxygen, pH, turbidity, and pressure, testing and control is very important in the aquaculture. At present, water instrumentation is often based on RS-232 or RS-485 in china aquaculture industry. However, wire communication mode is limited by wiring, is difficult in the special enviroment, is expensive and can not satisfy the large-scale faming. So a new detection method is needed to replace the existing detection methods. In the paper, WSN is used in multi-parameter, it is adapted to the modern large-scale factory faming.ZigBee WSN is used for data communication, it adapt to a number of parameter nodes and wide distribution. First, this paper analyzes the significance of the research and market value. Second, it describes briefly the general design plan. Third, the paper analysises datailed theoretical and circuit diaqram design of multi sensor. And last but not least, it in-depth studys ZigBee stack. Multi-parameter detection and ZigBee stack are combined and these can realize wireless sensor network. End node is combined by CC2430 SoC and it can realize filework intellective detection instrument. The controller of Router and coordinator is all composed by CC2430, and the coordinator can realize manifole function including liquid crystal display (LCD) of fieldwork, vision basic 6.0 (VB6.0) of long-distance inspect, button controlling and multi menu. These can realize multi-parameter of temperature, salinity, dissolved oxygen, pH, turbidity, and pressure and otherwise inspect. The system performs steadily and efficiently in practical test, and it can be easily applied to other monitoring areas, and a huge technological upgrading space and a good developing prospect.
