Learning type time-controlled tracking device and tracking method thereof

Abstract

The invention provides a learning type time-controlled tracking device and a tracking method thereof. A solar panel is used as a light sensing device to measure the daytime duration, and the tracking start and stop of the solar panel are determined. A travel limit switch is used as an azimuth reference. The daytime duration of the previous day is used as the tracking tine of the day, and the tracking rotation angle of the solar panel of the day is determined. The device can adapt to sunshine time changes and solar angle changes in different regions and different seasons, and completely gets rid of the influence of latitude, longitude and clock. The device provided by the invention has the advantages of simple structure, low cost, reliable operation and high adaptability, is less subject to environmental influence, and is free of manual setting and intervention. Compared with a real-time detection tracking system, the device is greatly simplified, is effectively prevented from the influence caused by climatic conditions and geographical environment, and has greatly improved reliability. Compared with the existing fixed-angle and fixed-duration time-controlled tracking method, the device has significantly improved tracking accuracy.

Description

technical field [0001] The invention belongs to the technical field of solar panels automatically tracking the sun, and in particular relates to a learning type time-controlled tracking device and a tracking method thereof. Background technique [0002] At present, most of them use the photoelectric tracking technology scheme of photoresistor switch to track solar energy. The advantage of this scheme is high sensitivity, but the disadvantage is that it is greatly affected by the weather. Brighter lightning at night will cause the tracking device to fail to track the sun, and even cause malfunction of the actuator. [0003] The traditional solar tracking technology only determines the inclination angle of the solar panel based on the collected current illumination parameters, completely ignoring the differences in the sun's orbit and sunshine time in different latitudes and seasons. Contents of the invention [0004] The object of the present invention is to provide a lear...
