Design of Hardware for Solar Power Generation System Data Acquisition and Transmission

In order to ensure the reliability of solar power generation system,some of the key parameters(such as current,voltage,frequency,etc.)needs to be controlled with real-time monitoring to comprehend the wroiking state of the whole system.Taking ST′s ARM9 as the core of the hardware platform,hardware design of the data collection and transmission sections in the monitoring system is described.RS 232,RS 485 and Ethernet communication interfaces based on ARM were developed to reaiyze the monitoring of the key parameters of the solar power generation system in order to control the solar power system real-time running situation.The efficiency of solar power generation system can be improved with the method.
