Problems solved by technology

[0002] At present, the solar azimuth measurement method mainly uses the direct detection of the difference in the intensity of sunlight on both sides of the sensor base surface to determine the azimuth, which will lead to confusion and unclear indication of the sensor under cloudy conditions, thus giving wrong azimuth feedback, resulting in the actuator being always in the In a state of chaotic operation, very few solutions based on the sun and shadow discrimination method are interfered by environmental pollutants, such as fallen leaves or dust covered sensors that produce shadows that cause interference and make it impossible to determine the true orientation

Embodiment

[0028] Such as Figure 1-4 As shown, the inventive method is based on the solar azimuth measurement sensor, which includes a base 1, a support 2 vertically fixed on the base 1 and a horizontal fixed axis 3 arranged on the support 2;

[0029] The horizontal fixed shaft 3 is provided with a circular base, and the upper surface of the circular base is provided with a projection needle 4; the projection needle 4 is perpendicular to the upper surface of the circular base; the projection needle 4 Made of opaque material, its bottom end is fixed at the center of the upper surface of the circular base, that is, the projection needle 4 is coaxial with the circular base;

[0030] The upper surface of the circular base surrounds the projection needle 4 with an annular photoresistor array 5, the annular photoresistor array 5 is composed of N photoresistors 5.2 numbered 1 to N arranged in series on the annular substrate 5.1 Composition; the adjacent photoresistors 5.2 on the annular subst...

Abstract

The invention discloses a method for measuring the azimuth of the sun, which is based on a sun azimuth measurement sensor. The azimuth of sunlight can be judged according to the shadow projected by aprojection needle on an annular photoresistor array, and the azimuth indicated by the sensor can be mapped according to azimuth angles corresponding to photoresistors numbered 1-N; in cloudy days without sunlight, the resistance of each photoresistor tends to be consistent due to small shadow identification degree, so that the sampled voltages are basically equal; and the sensor can output an invalid value so as to prevent frequent mis-adjustment when the sensor is applied to a solar cell panel azimuth adjusting mechanism.

Description

technical field [0001] The invention relates to a method for measuring the azimuth of the sun. Background technique [0002] At present, the solar azimuth measurement method mainly uses the direct detection of the difference in the intensity of sunlight on both sides of the sensor base surface to determine the azimuth, which will lead to confusion and unclear indication of the sensor under cloudy conditions, thus giving wrong azimuth feedback, resulting in the actuator being always in the In a state of chaotic operation, very few solutions based on the sun shadow discrimination method are interfered by environmental pollutants, such as fallen leaves or dust covered sensors that produce shadows that cause interference and cannot determine the true orientation. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above shortcomings of the prior art: to provide a method for measuring the azimuth of the sun which is ...
