Abstract : A great deal of various decentralize sensors are used in electrical machine state
monitoring system. In this paper, a real-time three-axes magnetic monitoring system of electrical machine is designed reasonably based on CAN. The three-axes magnetic sensor is designed and debuged, the node of sensor network is modularization designed, and the protocols of CAN’s transport layer is principly programmed. A smallest CAN system is constructed, which validated that the system based on CAN is feasible, real-time, effectively, and very dependable.
