A WSN-based large electrical equipment on-line monitoring system

In this paper, a new wireless sensor network (WSN) for large electrical equipment on-line monitoring is proposed, designed and implemented. The design of the wireless monitoring system emphasizes to solve the problems of traditional wired on-line monitoring system wiring too much, cost too high, fault diagnosing and maintaining difficulty and so on. The hardware design for wireless sensor network node and base station based on the CC2431 chip and the program design of transplanting TinyOS into the sensor nodes and base stations are discussed in detail. Then, a based on Visual C++ and database program technique system management software is proposed and implemented. The experiments show that the system possesses real-time data gathering, data storage and search, data curve drawing, low power consumption, wide coverage, no region limitation, and good operation performance.
