Solar power wireless monitoring system based on ARM7

In order to solve the problem of data monitoring in solar power system, the paper discussed the data acquisition of ARM7 and principle of serial communication. And the design scheme combined GPRS wireless communication and the highly effective energy conservation chip LPC2114 was presented, the system not only made the data information transmit to the monitoring center real-time and effectively, but also realized unmanned watching. In the system composition, this paper proposed modular design, which adopted RS485 communication between communication module. The design makes the data reliable transmission, the system structure is simple, and the performance is stable, which also provides conditions for the system upgrading in the future.
