Description
Technical field
The present invention relates to field of solar energy, in particular to a kind of tracking and device of solar tracking device.
Background technology
Traditional solar panels are fixed angle and orientation, can not fully effectively utilize sun power like this.If solar panels can be followed the tracks of the sun, guarantee that the incident angle and the solar panels of sunshine are perpendicular, then can improve the utilization ratio to sun power of solar panels.The appearance of solar tracking device has well solved the problems referred to above, and sun tracker can be realized the tracking to the sun, improves solar energy utilization ratio.
In existing solar tracking device, mainly contain following 3 kinds of control modes:
1) computing method: through local longitude and latitude and time, controller calculates the corresponding angle of each special time, controls whole device then and turns to suitable position.Controller can be selected single-chip microcomputer, DSP or other for use.
2) look-up table: calculate the corresponding angle of special time solar panels through PC, these data are kept in the controller,, control whole device and turn to suitable position then in these specific times.
3) sensor method:, continue the position of adjusting gear through the relation of current attitude of sun-sensor real-time detection apparatus and solar incident angle degree.

The mode of mixing control that adopts is also arranged in the prior art, and particularly, system adopts sensor method control when weather conditions are good, and system adopted computing method and look-up table when weather conditions were bad.Decision systems is operated in the factor of which kind of control mode and is in the mode of this mixing control: the signal to the sun angle sensor returns is judged; If the information that sensor signal is returned is for there being illumination; Then adopt sensor method control, otherwise adopt computing method or look-up table.This decision procedure is too simple, and several kinds of situation below the existence may cause erroneous judgement disconnected:
1) sensor sends wrong signal because causes such as the water inlet of raining have been gone bad.Sensor is because be directly exposed in the air, and needs optical processing system, and sealing property is relatively low, very easily damages.
2) sensor is operated in close-loop control mode because rainwater or leaf attached on the optical processing system, have been judged as illumination, but there is very mistake in the data of returning.
3) sensor is because non-solar irradiation causes misoperation.
It is thus clear that the solar tracking device of this mixing control is affected by environment bigger, system is unstable, thereby causes error bigger.
