摘要
为了改进对太阳的跟踪精度,提高太阳能的利用率,设计了一种基于ARM的新型的太阳跟踪控制系统;该系统利用32位ARM嵌入式微处理器芯片LPC2290作为控制器,通过程序对跟踪机构水平、俯仰两个方向的控制,实现对太阳的全跟踪;并在此基础上利用安装在跟踪机构上的角度传感器,对跟踪机构进行定时的误差校正,改进跟踪的精度;通过试验阶段的运行分析,此设计跟踪精度能够满足碟式太阳能热发电的需要,系统性能稳定,成本较低,功能扩展性强,具有较高的实用价值。
In order to improve the accuracy of tracking the sun and increase the utilization of solar energy, a new type of solar tracking control system is designed based on ARM . The tracking system uses a 32 ARM （Advanced RISC Machines） embedded mieroproeessor as a controller. It achieves entire track to the sun by controlling on the two directions of Level and pitehing. And on the basis, the tracking system timely eorrect errors to improve the accuracy of tracking by the angle sensor installed in the track mechanical devices. By the operation analysis of the pilot phase, tracking accuracy of the design can meet the needs of solar thermal power generation, system performance is stable, cheap, highly functional expansion. It shows high practical value.
