Design and Simulation of the Solar Tracking System.pdf

1、Scientists generally accept that for mankind the solar energy is the fittest, the safest,the most green and the most ideal replaceable energy in future .The current solarenergy converting rate roughly is 10％～20%.Analysis

2、 indicated that adopting thesolar tracker can increase 37% the rate of receiving energy .Research anddevelopment of the two axes solar tracker can increase the reception efficiency andopen widely the exploitation realm o

3、f the solar energy.
　　The studying content in this paper is the design of the solar tracking system andits electric control system．The system can realize tracking to the solar azimuth andaltitude angle in real time．We

4、 devised the position of the sun in celestial bodies,corresponding to design the two-dimensional position of the sun tracking devices andpropose the real-time tracking control program by the use of PC/104. The systemadop

5、ted active tracking, namely calculate the input angle of the tracking device inadvance by use of the clock module which is in the control system, the angle iscorrespondent to the sun position some moment．Photoelectric en

6、coders react thesunlight that putting on different position of the platform, feedback electricalsignal．Then PC/104 applies the subprogram and sends out pulse to DC torquemotors according to the signal, which can control

7、the rotate angle and direction of theDC torque motor．The mechanism has realized the automatic track to the sun, sothat the tracker's top flat board can be always vertical to the sunlight and arrive thefurthest receiving

8、energy．Systemic hardware select PC/104, it is used as control coreto control the DC torque motor. We have finished the design of the peripheralhardware circuit of single-chip. This driver adopted the special composite mo
