红外恒温控制器的设计与制作摘要：温度是一个很重要的基本物理量，在很多领域都要设计到，例如：冶金工业、化工生产、造纸行业、机械制造、电加热炉及家用电器等，都需要对其进行测量和控制，使被控温度保持在预先设定的范围内（即恒温控制）。在这里我们只设计一种低功率、低成本的恒温控制器。不同的状态可以通过蜂鸣器不同的声音提示进行判断，通过数码管显示控制时间和计时，通过按键启动工作和设定时间，通过单片机控制原理控制温度，升温至规定值开始恒温，并有相应 LED 灯指示。可以根据实际温度与设定温度之间的偏差输出两组 PWM 信号分别控制发热和制冷器件，从而达到箱内温度的恒定。关键词：红外；恒温；温度控制器1AbstractTemperature is a very important basic physical quantity, which needs to be designed in many fields, such as: metallurgy industry, chemical production, papermaking industry, mechanical manufacturing, electric heating furnace and household appliances, etc., all need to be measured and controlled to keep the controlled temperature within the preset range (that is, constant temperature control). Here we only design a low - power, low - cost thermostat. Different states can be judged by different sound prompts of the buzzer. The control time and timing can be displayed by digital tube. The working and setting time can be started by pressing the button. According to the deviation between the actual temperature and the set temperature, two sets of PWM signals can be output to control the heating and cooling devices respectively, so as to achieve a constant temperature in the cabinet.2目录....................................................................2......................................................2......................................................2....................................................4..........................................................4........................................................4.........................
