Abstract:    Wave power generation has become one of the effective means to alleviate the energy crisis. However, the wave energy power generation system is not always efficient and unstable, therefore, it is extremely important for monitoring the position and status of the wave energy power generation device. Based on Beidou satellite intercommunication, this paper designs an monitoring system which monitoring the operation of wave generating system, and will send information to the remote monitoring center, finally, monitoring system adjusts the operation parameters of wave power generation system. From the experiment, it can be concluded that the monitoring system plays a monitoring role and improves the output power.
