Problems solved by technology

Because it uses a sensor to accurately sense four-quadrant light, it can only be perceived when the light intensity is high, so its sensitivity is low
At the same time, the four-quadrant light device is prone to dust and is not easy to remove, which affects its control accuracy

Embodiment Construction

[0012] The present invention will be further explained below in conjunction with the accompanying drawings.

[0013] Such as figure 1 and figure 2 As shown, the high-sensitivity photosensitive system of the solar tracker includes a housing 2, a light intensity regulator and a spot receiving sensor. The light intensity adjuster can adopt two structural forms, the first is the combination of the condenser lens 6 and the color-changing mirror 7, and the second is the color-changing condenser lens 1 used alone. The housing 2 can be a cube or a cylinder, and the color-changing condenser lens 1 is preferably arranged on the top of the housing 2 and sealed with the housing 2, such as figure 1 shown. The condenser lens 6 is preferably arranged on the top of the housing 2, and a color-changing mirror 7 is arranged between the condenser lens 6 and the light spot receiving sensor, and is used in combination with the condenser lens 6. The condenser lens 6 is in phase with the housing ...

Abstract

The invention discloses a high-sensitivity light-sensing system of a solar light tracker, which includes a housing, a light intensity adjuster and a light spot receiving sensor; the light intensity adjuster is arranged on the housing, and the light spot receiving sensor The device is arranged in the housing, and the light spot receiving sensor is set at the light spot gathering place of the light intensity adjuster; the light intensity adjuster is a combination of a condenser lens and a color-changing mirror or a color-changing condenser lens; the light spot The receiving sensor includes a wiring board, a photocell assembly arranged on the wiring board and lead wires drawn from the wiring board. The high-sensitivity light-sensing system of the solar tracker of the present invention has outstanding advantages including: simple structure, convenient manufacture, cost saving, the lens itself also has a self-cleaning function, and is not easy to fall dust; the sun using the high-sensitivity light-sensing system The light tracker has the advantages of high sensitivity, easy control, and high precision. It has good economic prospects and can produce good social benefits.

Description

technical field [0001] The invention relates to a solar light tracking system, in particular to a high-sensitivity photosensitive system of a solar light tracker. Background technique [0002] Existing solar tracking devices are divided into two categories: electric and mechanical. Mechanical tracking devices are rarely used due to their disadvantages such as poor stability, low precision, and low sensitivity. Electric tracking devices are also High price, complex control, low precision and other shortcomings, but can not meet the requirements of use. A heliostat controller is disclosed in CN201037709Y. The heliostat controller includes a sunlight sensor and a control circuit. The sunlight sensor includes more than two groups of photosensitive elements, a hollow shading tube and an aimer, and the inner wall of the hollow shading tube There are at least a first group of photosensitive elements and a second group of photosensitive elements, and the control circuit includes a ...
