The sun position tracking system sensor has the advantages of simple structure, low cost, high precision and capacity of providing all-weather photoelectric signals and can be widely applied in photovoltaic industries.
Description
Technical field
The present invention relates to a kind of photovoltaic, particularly a kind of sun location tracking system sensor.
Background technology
The sun location tracking system sensor is used for the front end signal collection of accurate tracking position of sun system.The solar energy power generating utilization can be mapped on the photovoltaic panel very much in illumination, accomplishes through the photoelectric effect of photovoltaic panel then.As the energy-collecting device of photovoltaic generation is that the position of the battery windsurfing and the sun is closely related, if it is vertical with sunshine to remain battery windsurfing energy collecting face, can in limited scope, collect maximum sun power so.Research shows, solar facilities to the tracking of position of sun with do not follow the tracks of, its energy utilization ratio differs 30%, it is very necessary therefore to carry out round-the-clock tracking.In recent years, for reducing cost of electricity-generating, concentrating to generate power also comes into one's own more, and especially the volume production of high power concentrator battery (arsenic electrochemical cell) make the high power concentrator application more extensive, and high power concentrator is to sun location tracking accuracy requirement high (± 0.1 degree).Generally take the tracking means of Purely mechanical and the electromechanical tracking device of clock type at existing solar tracking device, tracking accuracy is on the low side, causes solar facilities daylighting effect bad.
Summary of the invention
The purpose of this invention is to provide a kind of high-precision sun location tracking system sensor, to improve to solar energy utilization rate.
In order to address the above problem, the present invention adopts following technical scheme:
Sun location tracking system sensor of the present invention has a lighttight cylinder, and the cylinder top is provided with transparency glass plate.The cylinder bottom is provided with an electro-optical package.On the electro-optical package in cylinder, be provided with photoelectric sensor in several, be provided with corresponding photoelectric sensor outside several along the cylinder outward flange along the cylinder inward flange.As preferably, the photoelectric sensor of cylinder outer edge is evenly distributed, and electro-optical package is divided into four quadrants, and when inside and outside photoelectric sensor respectively was 8, effect was better.Circuit board and hardware are set below the electro-optical package.The base back cover is used in the cylinder bottom.The height of cylinder can not be too high or too low, otherwise measurement and tracking effect are bad.For obtaining measurement effect preferably, cylinder heights should be between 0.8 to 1.5 meter, and measurement effect was best when wherein cylinder heights was 1 meter.
Sunshine is a semicircle crescent at the shade of the inside and outside formation of cylinder, and the shade thickness in the middle of the crescent moon is maximum, so the present invention can be distributed in inside and outside the cylinder with 8 inside and outside photoelectric sensors, and each sensor is preferably at a distance of miter angle.So at any time have at least 3 interior photoelectric sensors respectively, 3 outer photoelectric sensors are positioned at the shadow region, thereby guarantee precision, and can respond to the sunshine of each angle, do not stay the dead angle.
Sun location tracking system sensor of the present invention is divided into two kinds of mode operations, can be automaticallyed switch to high-precision fixed bit pattern by the coarse positioning pattern.When the tracking angular deviation was big, sun location tracking system sensor utilization cylindrical outer sensor sample cylinder shade of the present invention was followed the tracks of.Because the cylindrical outer shade is obvious inadequately, degree of accuracy is not high, therefore when angular deviation hour, system gets into accurately and follows the trail of.When the sunlight deviation got into a preset scope (being generally 0～5 °), photoelectric sensor was measured in the sun location tracking system sensor utilization cylinder.Because the effect of blocking of cylinder, the cylinder interior shade is obvious.According to the intensity of illumination of each quadrant in the four-quadrant, the sun location tracking system sensor obtains intense light irradiation quadrant and the low light level according to quadrant signal, and confirms solar azimuth in view of the above.
Beneficial effect: the present invention has simple in structure; Cost is low; Precision Gao Bingke provides the characteristics of round-the-clock photosignal; Therefore sun location tracking system sensor of the present invention has strengthened the formed shade scope of sun misalignment angle owing to used cylinder, so photoelectric sensor is measured more accurate.

Embodiment
With reference to the accompanying drawings illustrated in detail is carried out in enforcement of the present invention.
Embodiment 1
Please referring to Fig. 1, sun location tracking system sensor of the present invention includes transparency glass plate 1, cylinder 2, interior photoelectric sensor 3, outer photoelectric sensor 4, electro-optical package 5 and base 6.Cylinder 2 is processed for lighttight material, and the cylinder top is one meter to the electro-optical package height.Transparency glass plate 1 is arranged on cylinder 2 tops.Cylinder 2 bottoms are provided with electro-optical package 5.On the electro-optical package 5 in cylinder 2, be provided with interior photoelectric sensor 3 along the cylinder inward flange, photoelectric sensor 4 outside the cylinder outward flange has been provided with.Interior photoelectric sensor 3 respectively has 8 with outer photoelectric sensor 4, and 45 evenly is provided with according to being separated by.Electro-optical package 5 evenly is divided into four quadrants, and each quadrant all has 2 interior photoelectric sensors, 2 outer photoelectric sensors.Circuit board and hardware are set also with base 6 back covers below electro-optical package 5.
Open water placing flat of the present invention can be gathered the sunshine angle position in the sun.Sunshine passes transparency glass plate 1 irradiation and advances in the cylinder 2, simultaneously because the blocking of cylinder 2 lighttight barrels, on electro-optical package 5 with shading.Outer photoelectric sensor 4 can the perception shade the position, interior photoelectric sensor 5 can the perception cylinder in position and the intensity of interior each quadrant illumination of cylinder of shade.Sensor measurement of the present invention to above-mentioned information send into computing machine after, according to the program that writes in advance, can calculate the angle of sunshine, and control solar collecting device turn to sunlight.
Use solar tracking system sensor of the present invention, like 0.2 ° of sun angle deviation, then the shade length of sunlight generation is 3.49mm.0.54 ° the subtended angle because sun arrival point club has an appointment is when sunshine center incident sensor; To not have shade in the tube; And the shade of the outer 9.43mm that can have an appointment of cylinder is accomplished the signal of location with this as sensor.
