基于ARM的太阳跟踪控制系统设计

作者利用32位ARM（Advanced RISC Machines）嵌入式微处理器芯片作为控制器，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误差校正，改进跟踪的精度。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。

Design of a Sun-tracking System Based on ARM

In this paper,the tracking system uses a 32 ARM (Advanced RISC Machines) embedded microprocessor as a controller.It achieves whole process tracking to sun by controlling two directions of level and pitching.And on this basis,the tracking system can timingly correct errors to improve the accuracy of tracking by the angle sensor installed on the tracking device.The tracking accuracy of this design can meet the needs of solar thermal power generation with stable system performance,cheap cost and high expansion of functions.It shows high practical value.
