Dual-wireless communication photovoltaic power station remote monitoring system in RS485 bus architecture

Abstract

The invention provides a dual-wireless communication photovoltaic power station remote monitoring system in RS485 bus architecture. The dual-wireless communication photovoltaic power station remote monitoring system mainly comprises a data acquiring layer, a data relay layer and a data processing layer; a ZigBee wireless network of the data acquiring layer is used for immediately uploading the data of important power equipment in a distributed photovoltaic power station to the data relay layer, the data relay layer is used for sending the data to a remote database server at the data processing layer through a 3G wireless network so that an administrator of the power station can access the remote database server through the Internet to immediately check the scene running state. The system provided by the invention has the advantages that the monitoring system is designed to be out of the limitation of the distance of the photovoltaic power station, the manpower maintenance cost is saved; through the adoption of the dual-wireless communication mode of the ZigBee and the 3G, the condition of wiring at the complex power station scene is avoided while guaranteeing the data transmission rate and accuracy, the construction cost is saved.

Description

technical field [0001] The invention relates to the field of remote monitoring of photovoltaic power stations, in particular to a remote monitoring system for photovoltaic power stations with ZigBee and 3G dual wireless communications of RS485 bus structure. Background technique [0002] At present, solar photovoltaic power stations are mainly built in some remote and backward areas. The geographical environment of the site is complex and the public facilities are outdated, which is not suitable for the long-term on-site duty of the staff. , in the same area, the distance between various distributed photovoltaic power stations is relatively long. To realize the centralized management and monitoring of each distributed photovoltaic power station, it is urgent to realize the remote data monitoring of photovoltaic power stations. [0003] The existing monitoring system for photovoltaic power plants generally adopts a wired form or a single wireless form. At present, the power p...
