Abstract

The invention discloses a photovoltaic generation and large public building integration wireless remote networked monitoring system. Intelligent wireless monitoring devices are arranged at the output ends of each group of photovoltaic array and the input and output ends of each group of inverter, form an electric quantity data wireless acquisition network with a ZigBee central node, and converge acquired data to the ZigBee central node, and the node is connected and communicates with an RS485/RS232 converter and a ZigBee/general packet radio service (GPRS) wireless gateway to realize GPRS/Internet network-based electric quantity data wireless remote real-time transmission. Therefore, a monitoring center remotely monitors electric quantity information output by each photovoltaic array and the electric quantity information output in the grid-connected working of the inverters and a common power grid, an electric quantity database of a photovoltaic generation system is established, and a good informational foundation is laid for the scientific utilization of renewable energy sources.

Description
