Abstract
The invention provides a condensation sun automation tracking system. The condensation sun automation tracking system comprises: a solar energy collection module, a heat collector, a sensor and a CPU, wherein the heat collector is fixed on one side of the solar energy collection module through a support and receives sunlight reflected by the solar energy collection module; the sensor is fixed on the solar energy collection module; the CPU is connected with the sensor and the solar energy collection module. In the condensation sun automation tracking system of the invention, the sensor is used to monitor a focusing situation on the heat collector in real time; the senor is connected with the CPU and collected image information is processed; a focusing direction of the solar energy collection module is adjusted through the CPU. Therefore, the situation that focusing is not accurate due to mechanical drift can be avoided and thermal utilization efficiency can be increased.
Description
Technical field
The present invention belongs to field of solar energy on broad sense, in this solar tracking system field of refering in particular to focusing type solar heat collector, relate in particular to a kind of optically focused solar automatic tracking system.
Background technology
Solar collector especially refers to the pole axis tracking system device, follows the tracks of the motion of the sun with respect to the earth, thereby makes collection sun power, reaches higher efficient and lower cost.
The photovoltaic solar cell plate is widely used on the Application of Solar Energy of dwelling house or commerce.Because the motion of the relative earth of the sun, the sunshine that causes shining on the fixing photovoltaic battery panel has incidence angles in the different moment or annual different time every day.This kind incident ray can reduce the collection efficiency of solar panel and reduce the electric weight that this solar panel produces.Because the solar energy of collecting is directly proportional with cosine angle, i.e. angle between the vertical surface of the incident angle of sunshine and solar panel, the loss that this effect caused is the cosine losses of knowing.For improving the collection efficiency of sunshine, solar panel can use a tracker to make it keep approaching vertical position with sun incident light.
Tracker can be widely used on the focusing solar panels, through large-area optical collector with solar light focusing on a small size solar collector, this solar collector can be photovoltaic cell or photothermal converter.For focus is remained on the target receiver, this tracker will be followed solar motion, to keep focusing.
In the actual use; When large-area optical collector gathers sunshine on the one small size solar collector, because constantly moving of position of sun needs the eyeglass on the optical collector constantly to adjust direction; To focus on the solar collector; But optical collector is difficult to once sunshine perfectly gathered the center of solar collector, the edge of possible optically focused to solar collector, and this situation can reduce the service efficiency of sun power greatly.
Summary of the invention
The object of the present invention is to provide a kind of optically focused solar automatic tracking system, comprising: solar collection module; Heat collector is fixed in a side of said solar collection module through support, accepts the sunshine that said solar collection module reflects; Said optically focused solar automatic tracking system also comprises: a sensor, be fixed on the said solar collection module; One CPU links to each other with said sensor, said solar collection module.
Optional, said solar collection module is heliostat or fresnel reflector.
Optional, said sensor is cmos image sensor or four-quadrant position transducer.
Optional, said optically focused solar automatic tracking system also comprises an optical attenuator, said optical attenuator is overlying on the said sensor.
Owing to adopted technique scheme; Compared with prior art, the present invention has the following advantages: optically focused solar automatic tracking system of the present invention adopts the focusing situation on the sensor in real time monitoring heat collector, and sensor links to each other with CUP; The image information of collecting is handled; Regulate the focus direction of solar collection module again through CPU, thereby avoided mechanical drift to cause focusing on inaccurate situation, improved the efficient of heat utilization.
