1 电磁炉的设计与研究

摘 要

电磁炉是目前发展最快的，市场增长幅度最高的家电产品之一。开发的电磁炉具有成本低、界面多、功能齐全等优点，有一定的市场竞争力。本文基于感应加热原理，设计开发了电磁炉的控制系统，完成了电磁炉控制系统的硬件和软件设计，本文主要研究内容如下:

电磁炉的发展过程、工作原理、功能实现原理、硬件电路设计原理以及单片机程序的结构等。硬件电路主要包括主回路、控制电路、保护电路、电源电路和显示电路等单元回路。

电磁炉实现的功能:加热功能、定温功能、定时功能、无锅检测功能、报警功能，具体包括过热报警、过压或者欠压报警、风扇失效报警等。

显示界面是数码管显示界面。单片机的使用让电磁炉实现了智能化，主要包括提供良好的人机界面、功率自动控制、温度自动控制、定时控制以及各种自动检测报警等。该系统覆盖了电、机、磁等众多的知识。单片机程序结构分主程序和定时器中断服务程序两个部分，经过反复试验运行，程序运行稳定可靠。

Abstract

Induction cooker is one of the household electrical appliances whose development

is quickest and the market growth rate is highest at the present. The designed induction

cooker has advantages like low cost，many interface，complete function etc.So there is

a certain degree of market competitiveness . This paper designed the control system

based on the principle of induction heating and completed the control system’s

hardware and the software design of the induction cooker.The main content is as

follows:

This thesis introduces the development course，working principle，function

realizing principle，hardware circuit design principle as well as MCU Program’s

structure of induction cook. Hardware circuit includes the unit loop circuit such as

main loop circuit drive ，control circuit，protective cireuit，the circuit of power source

and displaying circuit etc.

Induction can achieve the following functions: heating function, constant

temperature function, timing function, no pot detection, alarm function. It specifically

including overheating alarm, overvoltage alarm , undervoltage alarm and fan failure

alarm.

The displaying interface is Digital Number Display Indicator.The use of MCU

makes the induction cooker intelligence,mainly offers good man-machine

interface,power automatic control and temperature automatic control as well as various

automatic detections alarm etc.MCU program structure divides into two parts as main

program and timet interrupt service program,after many times’testing and running,the

program runs steadily and reliably.
