【Abstract】 A general fault diagnosis platform for online analyzer system based on wireless sensor networks is proposed. To improve the system performance, layered instrument fault diagnosis mechanism, redundant network formation mechanism, "pulsation" mechanism of network and dynamic switch mechanism for end nodes in different networks are designed. Meanwhile, the hardware principle of end nodes and gateway modules as well as main software functions of wireless nodes and gateways are presented to realize a general fault diagnosis platform with high reliability and real-time. Finally, the practical applications are presented.更多还原
