[Abstract]:Energy shortage and environmental pollution have become a bottleneck restricting the development of society. Ocean energy, as a renewable and clean energy, mainly includes tidal energy, wave energy, temperature difference energy, etc. Countries all over the world pay more and more attention to the exploitation and utilization of oceanic energy. This project is supported by 2011 Special funding Project of Marine Renewable Energy, "Research and experiment on the key Technologies of Wave Energy supply for Ocean data buoy observing system", aiming at the ocean in the depths of wave power generation devices. The offshore monitoring system of wave energy generator based on STM32 is designed to monitor the working state of wave energy generator in real time. The maintenance mode of wave power generating equipment is changed from scheduled maintenance to condition monitoring and on-demand maintenance. Firstly, the paper introduces the basic structure and working principle of wave energy generator, and designs an offshore monitoring system framework for wave energy generation equipment, aiming at the monitoring requirements of voltage, current and rotational speed of wave energy generator. The system is mainly composed of data acquisition and processing module, data remote transmission module and data monitoring terminal. The system adopts master-slave structure, data monitoring terminal as host computer, data acquisition and processing module as slave machine. Based on this framework, the following contents are emphatically studied: 1 by analyzing the working principle of various voltage, current and rotational speed sensors and combining the requirements of the monitoring system, the Hall voltage sensor and Hall current sensor are selected. Hall speed sensor to collect the voltage, current, speed signal; According to the need of data remote transmission, DTU (GPRS data transmission unit is adopted as the data remote transmission module. (2) the sensor interface circuit and RS232 interface circuit are designed by using STM32F373VC microprocessor, and the slave computer program is designed. The function of A- / D conversion and speed calculation is realized. A Modbus communication protocol program is designed to package the monitoring data according to the Modbus communication protocol after the machine responds to the query message of the host computer, and sends the data to the DTU, through the RS232 interface. The data is transmitted to the host through the GPRS wireless communication network. 3 the software of data monitoring terminal is designed, and the network communication based on TCP protocol is realized by socket interface. The Modbus host program and the interface display program are designed. The host sends the query message to the slave, and the data monitor terminal receives and parses the data packet and the data display, and saves the data. Finally, in the laboratory environment, using frequency converter, motor, generator, three-phase rectifier bridge and DC electronic load to build a generator working platform, using the monitoring system designed in this paper to the generator voltage, current, The speed is monitored in real time. The experimental results show that the monitoring system works stably, achieves the expected design goal, and can meet the needs of offshore monitoring of wave power generation devices.
