With deepening research on wave energy converters（WEC）, it is urgent to develop a reliable and sound data acquisition and device control technology for WEC. According to the characteristics of the ＂Sharp Eagle No.1＂ floating wave energy converter, two independent monitoring subsystems have been developed, including the mobile PC monitoring subsystem based on wireless serial port with the functions of real-time data acquisition and wireless communication, as well as the SD card monitoring subsystem based on DSP with the functions of automatic data acquisition and storage. The monitoring system achieves real-time wireless monitoring of power generation data as well as automatic data acquisition and storage in SD card in the converter for the ＂Sharp Eagle No.1＂.The redundancy design by adopting different technology roadmaps improves the reliability of WEC monitoring system in real sea tests. The experiment results show that the monitoring system is featured by stable performance and low operating costs. The two sets of data from the two monitoring subsystems are real-time, comprehensive and complementary. The research is of great significance for analyzing the real-sea performance of WEC and promoting the development of wave energy.
