Problems solved by technology

This kind of tracking device is easy to design, and its disadvantage is that: general photosensitive devices have a wide photosensitive angle, and due to the scattering of sunlight, this method is not sensitive to the deviation of the sunlight angle; in addition, photosensitive components are often covered by dust , so that the light-sensing ability of the photosensitive element is weakened; or when the two photosensitive elements are polluted to different degrees. Their output will form an inherent deviation
The active tracking device avoids a series of problems in the passive tracking device. Its advantage is that it has high stability and can track the position of the sun accurately in theory. However, the actual situation is that due to the effect of the earth's atmosphere, sunlight will occur Refraction, which changes the angle of incidence of the sun, this refraction effect can cause significant errors in active tracking

Abstract

The invention discloses an active solar energy tracing method comprising the following steps: manually adjusting the initial posture of a solar energy device with an illuminated face to ensure that the illuminated face is vertical to an solar incident ray; obtaining current time; by taking the initial posture of the solar energy device and the current time as the references, obtaining device data according to the current time, and adjusting the direction angle and the altitude angle of the solar energy device at fixed time to realize active solar energy tracing. The invention also discloses a device used for the above solar energy tracing method, comprising a solar energy device with an illuminated face, a posture adjusting device of the solar energy device, a current time acquiring device, a controller and a press key system connected with the controller. The tracing method and the device of the invention have favourable precision and stability.

Description

Technical field [0001] The invention belongs to the field of industrial control, and specifically relates to a solar tracking method and device, in particular to an active solar tracking method and device. Background technique [0002] The solar tracking system can be used in various solar collection devices, especially solar power generation systems and solar water heaters, which can effectively improve solar collection efficiency. An efficient solar tracking system can be used as the sun rises and falls every day and the seasons change at any time. Adjustment. [0003] At present, the commonly used tracking systems mainly adopt passive tracking methods, that is, photosensitive devices are used to perceive the position of sunlight. Chinese patent ZL200510094900.8 discloses a sun tracking device and tracking method based on tracking attitude feedback. The device includes a sensor and a motor that are electrically connected to a light-receiving panel and a controller. The light-re...
