| Abstract: | In order to solve the monitoring need of large PV system,the technology of MCU,the display of screen menu,the technology of RS232 RS485 were investigated.After the analysis of cost,the execute time,the memory,the peripheral resources of MCU,the security and integrity of transmission line,the structure and content of menu,a complete hardware system and software system based on Atmega128 of AVR MCU,and RS232 RS485 technology of improved Modbus protocol were designed,then the monitoring on PV course was complemented real-timely,exactly,and detailedly.The results of testing indicate that this design achieves the expected target in time,content,function,and stability.This design proves to be data real-timely,functions plentifully and result finely. |
