摘 要本次课程设计的主要目的是用电子电路设计与实验热水锅炉温度控制器。让其实现在 6-23 时内 85℃以下一、二号炉开始工作并报警， 105℃以上一、二号炉停止工作并报警，冷却至 95℃一号炉开始工作，且在此期间用 LED 显示温度和工作时间。本次主要用到的方法是用电压比较器实现模-数转换、用计数器实现控制电路和记录工作时间、用一系列的门电路实现一定的逻辑功能；借助 Mulitisim 软件进行电路仿真，再在实验室连接元器件实现设计要求。设计的结果是可以让一、二号炉在特定的温度和时间下按规定工作，同时温度显示和记录工作时间来辅助控制器的工作。有效的控制锅炉工作大大提高了生产效率，也可以起到控温的作用，在实际生活中有重要的实践意义。关键词：锅炉；温度；计时；运算电路。AbstractThe main purpose of this course design is to use hot water boiler temperature control electronic circuit design and experiment. Let actually within 6-23 now below 85 ℃ furnace no. 1 and no. 2 to start working and call the police, above 105 ℃ furnace no. 1 and no. 2 to stop work and report to the police, cooled to 95 ℃ furnace number one begins to work, and during this period, with LED display temperature and time to work. The mainly used method is to use voltage comparator implementation mode - several transformations, counter is used to implement control circuit and record the working time, a series of gate is used to implement logic function; In the laboratory using Mulitisim circuit simulation software, and then connect components to achieve the design requirements. Design results can make furnace no. 1 and no. 2 under certain temperature and time to work according to regulations, at the same time temperature display and record the working time to assist the work of the controller. Effective control of boiler work has greatly increased the production efficiency, also can have the effect of temperature control, has importan...
