Embodiment Construction

[0025] In combination with the following application scenarios, the embodiments of the present invention will be described with reference to the accompanying drawings.

[0026] Photovoltaic modules (commonly known as solar panels) are made of solar cells (two specifications of the whole piece: 125*125mm, 156*156mm, 124*124mm, etc.) or solar panels of different specifications cut by a laser cutting machine or a steel wire cutting machine. Batteries are assembled together.

[0027] During the production of photovoltaic modules, or after the photovoltaic modules have been in operation for a long time, external defects such as cracks, fragments, and broken grids may occur on the cells. At present, the traditional defect detection is that professional technicians inspect photovoltaic modules, find abnormalities, identify and judge, and finally record the defect type. The purpose of the present invention is to timely and accurately detect the defects of the cells and reduce the cos...

Abstract

The invention discloses a remote photovoltaic module monitoring device. The device is electrically connected with a single photovoltaic module, and comprises a shell and a function module in the shell, wherein the function module comprises a sampling module, an adjustment module, a central processing module, a relay module, a wireless communication module and a defect detection module; the sampling module is used for collecting sampling data of the photovoltaic module; the adjustment module is used for adjusting output voltage and output current of the photovoltaic module; the central processing module is used for controlling the adjustment module to adjust the output voltage and the output current of the photovoltaic module after the sampling data is collected; the relay module is used for controlling short circuit and open circuit of the photovoltaic module; the wireless communication module is used for sending the sampling data and the processed data to a cloud server; and the defect detection module is used for carrying out defect detection on a battery piece in a sampled photovoltaic module image. The remote photovoltaic module monitoring device is capable of monitoring the working states of photovoltaic modules in real time and timely and correctly detecting the defects of abnormal battery pieces, so as to timely discover conditions and give alarms.

Description

technical field [0001] The invention relates to the field of photovoltaic modules, in particular to a remote monitoring device for photovoltaic modules. Background technique [0002] With the further development of solar photovoltaic power generation technology and its wide application, photovoltaic modules are an important facility for solar power generation, and more and more attention has been paid to whether the finished products of the modules are qualified. In distributed photovoltaic power plants, due to the series-parallel connection of photovoltaic modules, the DC voltage after confluence can reach thousands of volts. Since there is no special person responsible for daily management (such as 24-hour inspection), abnormal situations, such as some components not working properly, or even fires caused by excessive temperature or abnormal wiring, cannot be detected in time, which will inevitably affect the normal operation of the photovoltaic power station. To a certai...
