multisim太阳自动跟踪系统设计+程序+电路图

摘要太阳能作为新兴能源，储量丰富、绿色环保，有着化石能源无法比拟的优点。但是，就目前情况来看，太阳能利用率偏低，因此，提高太阳能利用率有着至关重要的意义。

本文主要对太阳自动跟踪系统进行了研究。首先，本文在论述课题的研究现状及意义基础上，介绍了光电跟踪及太阳运动轨迹跟踪的一维跟踪和二维跟踪；其次，给出了太阳高度角及方位角的计算方法，设计了太阳方位放大电路、光强放大电路、外部时钟电路、步进电机控制电路及单片机外部控制电路等电路，用multisim对电路进行了仿真，并用protel99se画了相应的原理图及PCB图；最后，介绍了太阳自动跟踪主程序框图、太阳运动轨迹跟踪程序框图及光电跟踪程序框图。65541

Title Design of automatic tracking system of solar

Abstract

As an emerging energy, solar energy is abundant and environmental and has the advantages that fossil energy does not have. However, the current situation is that the rate of solar energy utilization is low, therefore, improving the utilization of solar energy has important significance.

This paper focuses on the automatic solar tracking system. Firstly, , this paper introduces the photoelectric tracking and the solar trajectory tracking of the one-dimensional and two-dimensional tracking based on the present situation and significance of research. Secondly, it presents the method of solar altitude angle and the azimuth angle, the sun azimuth amplifying circuit, light amplifying circuit, the external clock circuit, stepper motor control circuit and MCU external control circuit. The simulation is carried out on the circuit with Multisim, and uses Protel99SE to draw the schematic diagram and PCB diagram . Finally, this paper introduces the automatic solar tracking of main program and block diagram and the flow chart of photoelectric tracking.

Keywords : solar power single-chip four-quadrant photoelectric sensors
