Photo-thermal power generation is as a kind of effective way of new energy development, more and more be applied in practice at present, the catoptron that traditional photo-thermal power generation system adopts mostly is monolithic minute surface fabricated structure greatly, that is: multiaspect monolithic mirror is fixed on the same support, reach the effect of orienting reflex by the position of regulating support, yet there is following shortcoming in this structure: pony support causes installed capacity low, can not practical requirement; Large-scale support physics poor stability, position regulating system power consumption height; The incident angle control accuracy is low.Therefore need the reflecting system of traditional photo-thermal power generation system is improved.
The utility model content
The utility model provides a kind of heliostat reflection control system based on earth's axis, test sun physical location by the solar azimuth angle tester in this system, and by signal processing circuit the signal of preset angle velocity information output in the pc is monitored, when if presupposed information and detecting information have deviation, by presupposed information in the treatment circuit countercharge PC, and followed the tracks of by the interlock of dsp controller control heliostat group's polar mounts mechanism.Heliostat is linear array, the initial position predetermined fixed, and the Dsp controller can be transferred to follower with the azimuth information of input, and control whole heliostat group's interlock and follow the tracks of adjustment, when position of sun changes a angle, heliostat normal position deflection a/2 angle.
The utility model adopts following technical scheme:
A kind of heliostat reflection control system based on earth's axis, establish the PC1 of preset angle velocity information in comprising, with signal processing circuit 2, dsp controller 3, scrambler 4, the motor 5 that is positioned at polar mounts follower 10 and a plurality of heliostat 6 linearly aligned heliostat groups that the interior PC1 that establishes the preset angle velocity information is connected successively, the solar azimuth angle tester 7 that can export position of sun signal 8 is connected with signal processing circuit 2.
Described heliostat group uses pole axis follower 10, the interlock of each heliostat azimuth mechanism, and initial position fixes, and light can be reflexed on the heat collector 9.
Dsp controller connects pole axis follower 10 by cable or wireless transmission.
The inaccurate problem of the tracking sun that the utility model adopts the real-time monitoring of sun tester can effectively solve with the variation of seasonal variations declination degree or no-fix causes well during because of initial installation.
Description of drawings
Fig. 1 is a kind of heliostat reflection control system figure based on earth's axis.
Fig. 2 is a kind of heliostat reflection control system synoptic diagram based on earth's axis.
Embodiment
In conjunction with illustrated in figures 1 and 2, in will comprising, establishes native system PC1, signal processing circuit 2, dsp controller 3, scrambler 4, the motor 5 that is positioned at polar mounts follower 10, heliostat 6, the solar azimuth angle tester 7 that can export position of sun signal 8 and the heat collector 9 of preset angle velocity information.
In this example, a plurality of heliostat 6 linear array become the heliostat group, and the heliostat group uses pole axis follower 10, the interlock of each heliostat position angle adjusting mechanism, and initial position fixes, and heat collector 9 places the place ahead, and each heliostat can reflex to light on the heat collector 10.In establish the preset angle velocity information PC1 be connected on the dsp controller 3 by signal processing circuit 2, dsp controller 3 can connect pole axis follower 10 by cable or wireless transmission.Solar azimuth angle tester 7 output signals 8 are connected to signal processing circuit, solar azimuth angle tester 7 not only can the real-time testing position of sun, the information of PC1 output that can also be by establishing the preset angle velocity information in 2 pairs of the treatment circuits is monitored, and uses this method can effectively solve with the variation of seasonal variations declination degree or no-fix causes well during because of initial installation the inaccurate problem of the tracking sun.Scrambler 4 connects motor 5, by scrambler 4 reception information, and outputs to motor 5, and drive motor 4 drives link gear and rotates, thereby makes each heliostat 6 deflections.Test sun physical locations by solar azimuth angle tester 7 in this system, and monitor by the signal of preset angle velocity information output in 2 couples of PC of signal processing circuit, when if presupposed information and detecting information have deviation, by presupposed information in the signal processing circuit 2 countercharge PC, and followed the tracks of by the interlock of dsp controller 3 control heliostat groups' polar mounts mechanism.Heliostat 6 is linear array, the initial position predetermined fixed, dsp controller 3 can be transferred to pole axis follower 10 with the azimuth information of input, controls whole heliostat group's interlock and follows the tracks of adjustment, when position of sun changes a angle, heliostat normal position deflection a/2 angle.
