Embodiment Construction

[0030] This solar photovoltaic two-dimensional brake tracking control system includes a motor control chip for solar photovoltaic panel steering, sensors, intelligent calculation storage units and operators, and is characterized in that the sensor is installed in parallel with the solar photovoltaic panel to actually measure and calculate solar energy The pitch angle and orientation of the photoelectric panel are fed back to the intelligent computing storage unit. There is a calculation program in the intelligent computing storage unit. According to the designed program flow in the automatic tracking mode, the control system will store the sunrise and sunset times and sunlight luminosity of each province in the memory. Comparing the set threshold with the real-time measured output voltage data of the sensor, judge whether it is sunny or cloudy, and switch freely between sunny and cloudy modes; several principles in the algorithm of the calculation program in the intelligent calc...

Abstract

The invention discloses a solar photovoltaic two-dimensional brake tracking control system. The system is characterized in that a sensor and a solar photoelectric panel are arranged in parallel, thereby actually measuring and computing a pitch angle and orientation direction data of the solar photoelectric panel so as to feed back to an intelligent computation storage unit MCU; daily experience sunrise, sunset and darkness time, and the illuminance data in the full-year at a use point are firstly stored in the intelligent computation storage unit, and the illuminance sum is greater than a setting value, and default value is 2.0V; a theoretical value is computed through a formula; according to a program flow under an automatic tracking mode of the control system, the intelligent computationstorage unit reads voltage data output by an epoxy plate, the set threshold is compared with the sensor voltage data to judge the sunny day or cloudy day and freely switch between the sunny day modeand the cloudy day mode. The device is compact in structure, high in stability, and high in expansibility, the damage on a motor by start current is reduced, the direct solar radiation direction is precisely located, and the power generation efficiency is improved. An the stable, efficient and intelligent photovoltaic power generation mode is realized.

Description

technical field [0001] The invention relates to a photothermal collection facility utilizing solar energy, a brake control device capable of automatically tracking the angle of direct sunlight, which is applied to a photothermal collection device with two-dimensional motion function requiring high efficiency in photovoltaic power generation. Background technique [0002] The structure, control circuit and sensor form of the existing automatic tracking control system for solar photovoltaic power generation devices are: [0003] 1. Fixed in the way of no freedom and horizontal rotation [0004] At present, a relatively common photovoltaic power generation mode is to place solar photovoltaic panels at an elevation angle of 45 degrees due to the south. Due to such a placement form, the equipment has no degree of freedom and cannot rotate, so the rated power generation can only be reached from 10:00 to 14:00 in summer. The advantages of this solution are low cost and easy insta...
