Design of the photovoltaic generating system signal acquisition card based on DSPIC30F3011

Briefly analyses the characteristics of photovoltaic generating system,and on this basis to determine the DSPIC30F3011 microcontroller as photovoltaic generating system controller,and design the outer core circuit and the software of the data processing.Using the characteristics of simple structure,additional RS232 combined LCD screen,for real photovoltaic generating system operation result shows.The experiment proves,signal acquisition card is simple in structure,reliable in operation.
