摘　　要：采用光感跟踪与时间跟踪相结合的方法,设计了全天候太阳方位跟踪控制系统。该系统包括监测装置、跟踪方式转换控制模块和双跟踪方式控制模块。监测装置监测天气状态为跟踪方式转换控制模块提供判断依据,跟踪方式转换控制模块发出指令启动相关跟踪方式,控制传动及支撑装置的运动,以改变太阳能电池板采光面的位置。系统的跟踪精度高,跟踪能耗低。The efficiency of photovoltaic generation system can be improved by using solar tracking device.But at present,sun tracking methods cannot adapt the change of climate and the energy of the system was wasted.In order to solve this problem,a new tracking method which combined the photovoltaic tracking method and time tracking method was presented and an all-weather control system for sun tracking was designed.The system includes the monitoring device,the switching control module and two-tracking control modules.The monitoring device is used to monitor the status of climate and send the information to the switching control module.The switching control module makes a judge and sends instructions.The two-tracking control modules start the right tracking style and controls the transmission-bracing device to change the position of solar battery unit.The new system can monitor the change of the climate in time and choose the reasonable tracking method according to the status of the climate.It can improve the tracking precision and reduce the energy consumption of sun tracking system.
