光源自动跟踪系统 摘要： 本系统是由两块TI公司的超低功耗的MSP430单片机作为整个系统的检测和控制的核心，结合现代的传感器与检测技术，完成了一个能够检测并指示点光源位置的模拟光伏发电太阳能光自动跟踪系统。本系统能全部实现基本部分要求的功能，也能完成发挥部分的要求。另外，我们的自动跟踪系统还能在跟踪点光源到终点线时，激光笔头能自动返回起并指向始点；同时，LED的电流也能进行调节；并且可以实时显示寻迹小车的运行时间和总时间。 本设计可以扩展为以后的太阳能发电的自动跟踪系统。该系统不仅能自动根据太阳光方向来调整太阳能电池板朝向、 结构简单、成本低, 而且在跟踪过程中能自动记忆和更正不同时间的坐标位置, 不必人工干预, 特别适合天气变化比较复杂和无人值守的情况, 有效地提高了太阳能的利用率, 有较好的推广应用价值。 Light source automatic tracking system Abstract: this system consists of two blocks of the TI ultra low-power MSP430 microcontroller core detection and control of the system as a whole, combined with modern sensors and measurement technology, completes a test and indicate the location point light source automatic tracking system of simulated solar photovoltaic power generation. Can all realize the function of some of the basic requirements of the system, and also completed the requirements for playing a part. In addition, our automated tracking system can also track a spotlight to the finish line, laser writing can automatically return and point to the starting point; at the same time, LED current can be adjusted and can show in real time tracking of the car and total time.　　　 This design can be extended for subsequent automatic solar tracking systems. Not only does the system automatically according to adjust the solar panels toward the Sun direction, simple structure, low cost, and can automatically track memory and correct coordinate locations at different times, without human intervention, particularly suitable for weather changes are more complex and unattended conditions, effectively improve the utilization of solar energy, a better application of value. 目录 1.系统方案选择与论证 1.1.1任务 1.1.2要求 1.2系统方案对比论证 1.2.1系统总体方案设计 1.2.2各模块方案选择与论证 1.2.3系统各模块的最终方案 1.2.4小车电机驱动模块 1.2.5恒流源模块 系统的软硬件设计与实现 2.1.系统硬件基本组成部分的设计思想 2.1.1控制部分 2.1.2检测部分 2.1.3功能实现部分 2.2系统的软件设计 2.2.1系统主程序流程图 2.2.2各部分子程序 3系统测试、调整 3.1各部分测试过程和数据 3.2整系统测试 3.3测试
