基于单片机的电热水器控制系统设计

笔式数字万用表题目基于单片机的电热水器控制系统设计

摘要

近十余年来，单片机技术的发展极为迅速，广泛应用于生产、生活的各个领域。本文所设计的控制系统采用AT89C52单片机作为控制核心，利用AT89C52现有的接口组织外围硬件模块。然后分硬件和软件两部分进行阐述。硬件是指以温控制器为核心，由外接温度测量电路、实时时钟电路、键盘、复位与看门狗电路、热水器加热开关、LED显示电路组成。而软件部分则主要是为系统功能的实现而进行的编程和结果的仿真。

本设计采用模块化设计，在主程序模块下分成若干彼此独立的分模块：包括主控模块，温度采集模块，显示模块等，并且通过单片机将各个模块连接起来，形成一个完整的整体。本系统可以实现对温度的采集与显示、时钟的显示、热水器开机方式的控制等，非常有实用价值。

Abstract

The recent ten years, microcontroller technology development extremely rapidly, it is widely used in production, life and in all areas. The design of control system adopts AT89C52 single chip computer as the controlling core, and using of the existing interface organization as the hardware modules. Then described it by two parts that are hardware and software. Hardware refers to the temperature controller for the core, with outside temperature measurement circuit, real-time clock circuit, keyboard ,reset and watch-dog circuit, water heater heating switches, LED display circuit component. While software part then is mainly to simulate the result and to program the realization of system function.

This design uses the modular design, with the main modular, it is separate into several independent program modules. Including control module, temperature module, display module and so on, and will connect each module by the single chip computer, forming an

integral whole. This system can realize the collection and display of the temperature, clock display, the control ways of the water heater .So it has highly practical value.
