Embodiment Construction

[0008] Such as figure 1 As shown in , the probe of the self-adaptive solar automatic tracking sensor for photometric sensing accuracy of the present invention includes a photocell base 1 , photocells 2 and 3 , and photoresistors 4 and 5 . The photocells 2 and 3 are installed on the photocell base 1 at an obtuse angle inwardly, and the photoresistors 4 and 5 are respectively installed on the left and right sides of the upper surface of the photocell base, and are respectively connected with the opposite photocells. figure 1 The upper left corner is marked with the X-axis, Y-axis and Z-axis corresponding to the schematic diagram of the sensor of the present invention. The space Cartesian coordinate system, the probe can be installed on the device that needs to rotate around the Z-axis to provide a drive signal for the corresponding servo mechanism. The light source that needs to be tracked (such as the sun) emits light on the photocells 2 and 3. When the sensor is not facing the...

Abstract

The invention provides a solar automatic tracking sensor which can independently adjust the tracking precision according to the change of the intensity of sunshine. The sensor adjusts the sensitivity of the whole sensor by using the characteristic that the resistance value of the photoresistor changes with the change of light intensity, and uses the voltage generated by the photocells at an angle to be compared with the comparator to output an electrical signal to drive the motor to rotate and adjust the angle of the panel to track the sun. . It can make full use of energy and reduce system wear.

Description

technical field [0001] The invention relates to a solar tracking sensor capable of adaptively adjusting tracking precision according to the intensity of light, and belongs to the technical field of solar energy applications. Background technique [0002] In the field of solar energy, real-time automatic tracking of the sun is an effective way to improve the utilization rate of solar energy, so many solar power generation systems use real-time automatic tracking to generate electricity. When the automatic tracking power generation system is under good sunshine conditions, only high-precision tracking can efficiently use solar energy. If lower precision tracking is used, the system's utilization rate of solar energy will be reduced. However, if the system still tracks with high precision under poor sunshine conditions, such as cloudy and rainy days, morning and evening, it will cause the automatic tracking system to waste energy and accelerate wear and tear. In order to give...
