北京理工大学珠海学院 2016 届本科生毕业论文激光器电源高精度温度控制系统硬件设计激光器电源高精度温度控制系统硬件设计摘 要随着激光加工技术的发展，激光器也在不断向前发展，激光器已成为现代激光加工系统中必不可少的核心部分之一。激光器的正常运行需要有稳定的电源供应，即激光器电源，激光器电源系统是一种受控供电系统，决定着激光器运行的状态。硬件电路是电路系统的重要组成部分，其设计的合理性直接影响电路系统的性能。本论文以激光器电源为研究对象，对其工作温度进行高精度采集，通过 A/D 转换器进行采集放大温度模拟信号，把模拟信号转换为 STM32 单片机可以接收到的数字信号，即电压信号，后 MCU 通过实时检测温度与散热扇的转速运用 PID 算法调控 PWM 占空比达到对散热扇的转速控制，并反馈数据显示在显示屏上，从而达到激光器电源高精度温度控制，本论文针对激光电源的发热问题，提出了一种温度控制器的硬件方案，设计了 PCB 电路，分析了散热性能。关键词：激光器电源；温度控制系统；STM32 单片机；硬件电路设计；PCB北京理工大学珠海学院 2016 届本科生毕业论文Hardware design of laser power supply high precision temperature control systemAbstractWith the development of laser processing technology, lasers are also constantly moving forward. Lasers have become one of the indispensable core parts in modern laser processing systems. The normal operation of the laser requires a stable power supply, that is, the laser power supply. The laser power supply system is a controlled power supply system that determines the operating state of the laser. The hardware circuit is an important part of the circuit system, and the rationality of its design directly affects the performance of the circuit system.This thesis takes the laser power supply as the research object, collects its working temperature with high precision, collects and amplifies the temperature analog signal through the A / D converter, and converts the analog signal into a digital signal that can be received by ...
