Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] figure 1 The overall module structure of the solar tracking system is shown. The photosensitive sensor 1 transmits the current signal to the circuit 2, and the circuit 2 transmits the processed signal to the MCU data processing system 3, and the MCU data processing system sends a signal to the driving mechanism 4 according to the corresponding light intensity, azimuth angle and altitude angle signal, so as to Adjust the orientation of the solar installation. The drive mechanism includes a program tracking part and a stepping drive part. The program tracking component is used to calculate the sun position according to the program when the light intensity is insufficient, and obtain the maximum possible light-receiving surface. When the light intensity is sufficient, the signal is received and processed by the azimuth stepping motor drive circuit 4-1-1...

Description

technical field [0001] The invention belongs to the field of solar energy utilization, and in particular relates to a solar tracking sensor control circuit. Background technique [0002] In solar energy utilization, it is desirable to keep the device facing the direction of direct sunlight to ensure the most efficient use of sunlight. The solution adopted is to use a tracking sensor to generate a signal, and the driving device adjusts the orientation of the solar device according to the signal. The entire tracking sensor includes a photosensitive sensor and a circuit. The photosensitive sensor outputs the detection signal to the circuit. The circuit generates azimuth and altitude angle signals after processing, and outputs them to the drive system after being processed by the data processing system. The drive system adjusts the azimuth and altitude according to the corresponding signals. angle to keep track of the sun. Contents of the invention [0003] The invention pro...
