Abstract

The invention provides a system and a method for communication non-interference type channel extension in a photovoltaic power station. Operating data of intelligent equipment of the photovoltaic power station are connected with a communication acquisition unit in a monitoring system host machine through a communication channel. The system comprises a port server and a logic analyzer which intercommunicate through a bus; the system also comprises a real-time data base and a watch dog module which are respectively connected with the logic analyzer; the port server of the system is respectively connected with an intelligent equipment communication channel and a monitoring equipment communication channel; the logic analyzer is connected with a scheduling monitor system by extending the communication channel. According to the system and the method, the channel is expanded on the basis that the original communication channel is not damaged or attenuated.

Description

technical field [0001] The present invention relates to a method in the technical field of photovoltaic power station monitoring, in particular to a system and method for communication non-interference channel expansion of photovoltaic power station. Background technique [0002] In recent years, new energy represented by solar energy and wind energy has developed rapidly around the world. At present, solar energy is one of the most promising clean energy sources in the world, and all countries regard the utilization of solar energy resources as an important part of building sustainable development strategies.
