摘要
构建了基于四象限探测器的双轴机械式自动跟踪定位装置,以低功耗单片机MSP430为核心,设计了使太阳能板始终保持与太阳光垂直的自动跟踪系统,大大提高了太阳能的利用效率.采用高性能的放大电路、滤波电路、A/D转换电路及精密步进系统,控制精度高,直线跟踪精度达到0.25μm,视场的跟踪角精度为0.25 mrad,满足设计要求,对于太阳能的应用技术具有较大的参考价值,具有广泛的应用潜力.
Based on four-quadrant photodetector, a double axle autotrack machinery equipment is designed with the low-power MSP430 SCM as its core. It enables the sun panel to keep being vertical to sunlight, so the utilization efficiency of solar energy was greatly improved. The equipment consists of the amplifying circuit, fitter circuit, integrating circuit, A/D converter and precise stepping system. The linear tracking precision is up to 0.25μm, and the tracking precision of coverage angle is 0.25 mrad. The research is helpful to the applications of solar energy.
