The specific embodiment
Be described in further detail below in conjunction with the structure and the operation principle of accompanying drawing control device for tracing sun position provided by the present invention.
Fig. 1,2,3 and shown in Figure 4 is the calcspar of control device for tracing sun position provided by the present invention and the sensing mechanism structural representation that constitutes control device for tracing sun position.Constituting this control device for tracing sun position comprises: thickness is at the base plate with certain mechanical strength 1 of 5-20 millimeter, this base plate is provided with the double-layer cross shape light barrier 2 that is made of eight light barriers of certain altitude, 3,4 and 5 (wherein, double-deck light barrier spacing is the 0.5-10 millimeter, the height of double-layer cross shape light barrier is 10-100 a times of double-deck light barrier spacing), the place, four angles that forms at light barrier on the base plate is provided with four circular holes 6 respectively, 7,8 and 9, in these four circular holes, be fixed with first respectively, second, the third and fourth photo controller spare 10,11,12 and 13 are individually fixed in the above-mentioned circular hole.The light barrier 2 that constitutes double-layer cross shape light barrier and 5 and 3 and 4 also is that horizontal direction and vertical direction are respectively arranged with two circular holes 14,15, is fixed with the 6th and the 7th photo controller spare 16,17 in these two circular holes respectively; Above-mentioned formation plays sensing mechanism.Wherein, first, second, third, fourth photo controller spare and the 5th and the 6th photo controller spare pass through mould/number conversion processing mechanism 18 circuits and data microprocessor 19 respectively, and the transducing signal processing mechanism that constitutes; Above-mentioned signal by microprocessor respectively the level by first and second drive circuits 20,21 and control solar aggregation apparatus to vertical to rotation control the controlling organization that motor 22,23 connects and composes.
The operation principle of above-mentioned control device for tracing sun position is:
When system works, at first by gathering in the base plate or the luminous intensity of six pairing six zonal rays of light-sensitive element fix, be input to the A/D conversion module with the form of voltage, input to the single-chip microcomputer processing again.
System adopts twin shaft control, orientation control and elevation angle control.At first carry out orientation control, one, two, three, four district's intensity signals according to the first, second, third, fourth photo controller spare place correspondence that collects in real time, analyze through the microprocessor comparison operation, draw the relative position information of the sensor and the sun, output port output control information by microprocessor, be input to motor-drive circuit by photoelectric isolating circuit, decide the direction of rotation of orientation control either-rotation motor; When orientation control either-rotation motor begins to rotate, microprocessor just begins the intensity signal in five districts of the 5th photo controller spare correspondence is carried out continual circulating sampling analysis, and each light intensity value is stored in a certain memory cell, so that compare with next sampled result, sampling analysis once takies 0.1 second approximately.Because the rotation of orientation control motor, drive mechanism makes daylighting equipment and sensor move towards solar direction, the light intensity in five districts can constantly strengthen, when in a single day processor finds that the light intensity in five districts begins to reduce, expression daylighting equipment and sensor begin solar motion dorsad, and processor can send the motor instruction that stops operating immediately, orientation control finishes, and begins elevation angle control then.In like manner, processor is according to one, two, three, the four district's intensity signals that collect in real time, analyze through the microprocessor comparison operation, draw the relative elevation location information of the sensor and the sun, output port output control information by microprocessor, the operation of control elevation angle control motor, begin simultaneously the intensity signal in six districts of the 6th photo controller spare correspondence is carried out the circulating sampling analysis, in case find the light intensity decreasing in six districts, processor can send the motor instruction that stops operating immediately, elevation angle control finishes, and finishes once and adjusts.
Because factors such as influencing each other between the control of machine error and orientation and the elevation angle control, a twin shaft adjustment may precision not reach requirement, can be provided with by program to carry out 2-3 adjustment continuously, finishes once complete double-axis tracking and controls.
In above-mentioned control device for tracing sun position:
---because the reflection of light and the light intensity parameter of the sun direct projection of photo controller spare is exerted an influence, the base plate and the light barrier that constitute the sensing mechanism structure adopt black material to make, or get final product in its surperficial blacking in order to reduce; In order to overcome the problems referred to above, sealing strip 25 sealings are adopted in four the end 24 that double-layer cross shape light barrier forms equally.
---in order to improve the control accuracy of control device for tracing sun position, the double-deck light barrier spacing that constitutes double-layer cross shape light barrier is set, generally be set between the 0.5-10 millimeter; The height setting that constitutes double-layer cross shape light barrier simultaneously is between 10-100 times of double-deck light barrier spacing.
---get final product in order to simplify the structure of the sensing mechanism that constitutes control device for tracing sun position, directly the first, second, third, fourth, the 5th and the 6th photo controller spare to be fixed on the base plate.
