Photovoltaic power plant all-sky scanner

1. Overview of photovoltaic power station all-sky scanner

Photovoltaic power station all-sky scanner is also called photovoltaic power station sky scanner and photovoltaic power station cloud monitor. Photovoltaic power station all-sky scanner uses all-sky cloud images to obtain cloud motion vectors and cloud shapes of different thicknesses in the future time period. Trend. With the development of natural science, cloud observation continues to be valued. In the early days, cloud observation required professionals to observe with the naked eye and manually record the observation results. The accuracy of the observation results varied greatly depending on the experience and technical level of the observer. In order to reduce labor costs, improve observation accuracy, and realize unattended all-weather automatic observation of the sky, manual observation is gradually replaced by photovoltaic power station all-sky scanners. The photovoltaic power station all-sky scanners are combined with the application of machine deep learning algorithms, which greatly It improves the degree of automated cloud observation and enhances people's ability to research and utilize solar energy resources.

2. Function description of photovoltaic power station all-sky scanner

The FT-TK2 photovoltaic power station all-sky scanner is a new generation of fully automatic, full-color sky imaging equipment independently developed by our company. The equipment has a large viewing angle of 220°. Through IOT intelligent network technology, it can obtain real-time image information and Meteorological data is transmitted to the back-end computing center. After the data is processed by quality control and AI image recognition models, real-time image data, cloud coverage, light transmittance and additional weather data are provided to user terminals in various forms.
