product details

I. Overview

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 achieve unattended, all-weather automatic observation of the sky, all-sky imagers are gradually replacing manual observations. All-sky imagers, combined with the use of machine deep learning algorithms, have greatly improved cloud visibility. The degree of automated observation has enhanced people's ability to research and utilize solar energy resources.

2. Function description of FT-TK2

The FT-TK2 all-sky imager 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. It is transmitted to the back-end computing center, and 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.
