Design and Realization of Solar Cell Monitoring System Based on Wireless Sensor Network

Aiming at solar cells of the photovoltaic power station in decorate with remote, quantity, and easy to change and variety of features, this paper introduces a kind of wireless sensor network through real-time monitoring solar cell module, the design of the working state of the solar cells will be sent to the PC, make management through the PC interface can know exactly what the working state of every board, thus greatly simplify the maintenance of photovoltaic power station. First, through the source node acquisition solar cells of the voltage and current information, and the wireless network will carry information to base station node, the base station each node receiving the information source node and through the serial line transmitted PC. The whole monitoring system used the CC2430 as the main hardware platform and software of the ZigBee protocol stack. The experimental results show that the relative error voltage in 0.4 V within the current relative error in 0.04 A less than. The stability of the system is better, and satisfactory to solar cells monitoring stability requirement.
