Photovoltaic power generation system data collecting device and collecting method based on Zigbee

Abstract

The invention discloses a photovoltaic power generation system data collecting device based on a Zigbee. The photovoltaic power generation system data collecting device comprises a plurality of collectors and at least one collecting gateway. The collects are respectively connected with at least one detected device of a photovoltaic power generation system and collect and send the electric power data of the detected device. One end of the collecting gateway is connected with at least one collector through a Zigbee wireless network and receives the electric power data, and the other end of the collecting gateway is connected with a power station monitoring server and uploads the electric power data to the power station monitoring server. Compared with the prior art, distribution type photovoltaic power station monitoring is achieved through the mode of the Zigbee wireless network, the monitoring problem of large-scale photovoltaic power stations and photovoltaic power stations similar to village distributed type roofs can be solved, pulling and burying road-crossing cables are of no need in using process, data traffic cost is avoided, and low cost and intelligent management of the power station is achieved. In addition, the invention further discloses a photovoltaic power generation system data collecting method based on the Zigbee.

Description

technical field [0001] The invention relates to a data collection device and a collection method, in particular to a data collection device and collection method based on a Zigbee photovoltaic power generation system. Background technique [0002] With the gradual maturity and improvement of photovoltaic power generation technology, in order to meet the needs of photovoltaic power generation into the grid, it is necessary to implement real-time monitoring and information collection for photovoltaic power generation to ensure the stability of photovoltaic power generation systems. The real-time monitoring data of photovoltaic power generation include: meteorological parameters of the system working environment, mainly including temperature, solar radiation intensity, wind speed and forecast of severe weather; secondly, the working voltage and current of solar panels; all the above information is obtained by the power station monitoring system through the communication channel ...

AI Technical Summary

Problems solved by technology

[0003] The monitoring system of the current distributed rooftop photovoltaic power station generally adopts the following schemes for data collection: 1. Use a collector with GPRS as the communication interface, and all data will be returned to the central server through GPRS. This method is due to the GPRS data traffic The cost is more expensive, which increases the cost of system operation; 2. To use an industrial-grade wifi network, an industrial-grade wifi network needs to be built, and the network cost is relatively high; 3. Use 485 data lines and optical fibers to monitor each roof independently first, and then Connect to the central server in the form of Ethernet, the single monitoring cost of this method is relatively high
