Automatic operation and maintenance system of large-scale photovoltaic power station based on Beidou and SLAM fusion

Abstract

The invention relates to the technical field of photovoltaic operation and maintenance, and discloses an automatic operation and maintenance system of a large-scale photovoltaic power station based onBeidou and SLAM fusion. The system comprises at least one operation and maintenance robot provided with a Beidou communication module and an edge computing processor, and the operation and maintenance robot is further provided with a visual sensor, a thermal infrared imager and a laser radar sensor which can exchange information with the edge computing processor; and the Beidou communication module communicates with the edge computing processor through an SPI, a Mesh module is further arranged in the Beidou communication module, and a plurality of SLAM algorithm modules are arranged in the edge computing processor. The automatic operation and maintenance system has the beneficial effects that the specific position and size of a hot spot are accurately detected by utilizing each sensor, and by means of a Mesh networking technology and an SLAM algorithm, the offset power generation amount caused by the hot spot can be accurately calculated while a hot spot distribution image of a photovoltaic panel in the whole area is obtained. And finally, the information such as the accurate position of the hot spot is transmitted to a remote data center without obstacles through a short messagetechnology carried by the Beidou.

Description

technical field [0001] The invention relates to the technical field of photovoltaic modules, in particular to an automatic operation and maintenance system for large-scale photovoltaic power plants based on the integration of Beidou and SLAM. Background technique [0002] Photovoltaic modules are the core components of photovoltaic power plants, any small problem can cause huge losses, and the "hot spot effect" is undoubtedly the most troublesome problem, because hot spots may cause damage to the entire photovoltaic module. It is understood that a hot spot that occupies about 1 / 60 of the battery area will affect 1 / 3 of the power generation of the entire photovoltaic panel, and will also reduce the service life of photovoltaic modules by at least 10%. In severe cases, the solar cell modules will be permanently damaged or even burned, causing irreparable losses. [0003] "Hot spot effect" means that under the sunlight, some components of photovoltaic modules cannot work norma...

AI Technical Summary

Problems solved by technology

[0007] Manual inspection makes it difficult to find hot spot problems with the naked eye; the module area is too large, the inspection cycle is long, and hot spots are not found in time; when the terrain and environment of photovoltaic power stations are relatively complex, manual inspections have great potential safety hazards

[0008] Unmanned aerial vehicle inspections cannot accurately mark the location of hot spots, and cannot accurately judge the degree of hot spots
