GPRS Based Monitoring System of Solar Photovoltaic-illumination Tunnels

In the illumination of decentralized tunnels in indigent power region, which is difficult to achieve the centralized monitoring and unified management, the intelligent monitoring system of solar photovoltalc-illumination tunnel is an ideal method. An embedded controller was adopted in this paper, and the monitoring system was designed for solar photovoltaic-illumination tunnels based on GPRS wireless communication data remote transfer. The paper presents the composing and the key technology of system. The hardware structure and software flowchart of the illumination controller have been presented in detail. The experiment shows that the system can control the illumination of tunnel according to the standard. The system has reliable performance and is of value to popularization.
