(完整word版)基于单片机控制的快热式电热水器设计(2稿).doc

用电器不断的深入人们的生活，家用电热水器也满足不了这飞速发展的时代了，快热式电热水

器的使用逐渐普及开来了。

单片机来控制电路。本设计主要分为两个部分，硬件电路设计和软件仿真。硬件电路设计主要

包括加热控制电路，报警电路，LED 显示，温度监控等,本设计使用双向可控硅,用单片机通过光

耦给可控硅触发信号，可控硅的导通角就会随之变化，从而控制电热丝的有效加热功率，并且

串联 105℃的熔丝来防止温度过高时加热管干烧；软件包括主程序的设计，温度检测程序设计，

频率测温程序设计，显示扫描程序的设计等，程序主要由 C 语言编写,并给出了仿真图设计。

appliances into people's lives, home electric water heater also meet era of the

rapid development of the ， fast heating type electric water heater use grew in

popularity to open the.

SCM is the core of the design controller, with keyboard, monitor and other

intelligent integration. This design uses AT89C51 microcontroller to control the

circuit. This design is mainly divided into two parts ， hardware and software.

Hardware mainly includes heating control circuit and alarm circuit, LED display，

temperature monitoring, using a bidirectional thyristor, MCU through the coupler

to SCR trigger signal ， control thyristor conduction angle, and control the

effective electric wire heating power, and series 105 DEG C molten wire to prevent

very considerable development prospects。
