Abstract

The invention relates to a direct-current carrier authentication system and authentication method for monitoring a photovoltaic module. The authentication system comprises a voltage acquiring circuit, a current acquiring circuit, an environment monitor, an MCU micro-processor, a carrier communication module and a power supply management module. The authentication method is used for the interactive control and identification authentication between a main combiner box monitoring node and a sub-photovoltaic module monitoring node. By means of the technical scheme, the direct-current carrier authentication system and authentication method for monitoring the photovoltaic module can solve the difficulties in photovoltaic module fault monitoring and communication guarantee of an existing solar power system. The direct-current carrier authentication system and authentication method for monitoring the photovoltaic module can monitor the voltage, current, temperature and other similar information of the photovoltaic module in real time and upload data or issue a command by means of the direct-current carrier technology so as to quickly discover a photovoltaic module fault, improve the system working efficiency and guarantee the monitoring system data security.

Description

technical field [0001] The invention relates to the technical field of new energy photovoltaic module monitoring, in particular to a DC carrier safety authentication system and authentication method for photovoltaic module monitoring. [0002] Background technique [0003] At present, it is mainly checked whether the photovoltaic modules are working normally by monitoring the current and voltage of the inverter in the solar power generation system. This method can only monitor whether a certain string of photovoltaic modules is working normally, and cannot accurately locate the faulty solar panel at the first time. If a solar panel is damaged in the component array of a large-scale photovoltaic power station, it will bring losses to the power generation system, and relying on manual inspection is time-consuming and laborious, which cannot meet the requirements for system emergency repair. In addition, most of the communication methods in existing solar power generation sys...
