摘要

本设计不仅具备油烟机基本开关功能，而且还能根据厨房在烧菜做饭过程中

产生的油烟气温度高，而泄露的天然气温度低的特点，采取不同的传感器件，即

对温度高、污染大的烟气采用数字温度传感器检测，而温度低但危险较大的天然

气采用气敏传感器检测，当厨房的油烟或可燃有害气体达到一定浓度的值时，经

传感器进入单片机分析，使电机电路自动启动并发出声音报警，油烟机迅速将有

害气体抽走。本设计有定时功能，可对抽油烟机进行工作时长的设定。论文的硬

件部分主要设计了油烟机的按键输入模块，对油烟燃气温度、浓度的检测模块，

显示模块，执行电路模块，声音报警模块等，系统软件部分主要是对各模块的流

程做了详细的分析，控制主程序、中断按键扫描子程序、显示子程序，中断报警

服务程序，以此从而实现抽油烟机自动控制功能。还分析了饮食业油烟污染的危

害和油烟净化设备的现状，还附带了油烟净化系统。油烟净化系统的设计是通过

对油烟的流量以及压力的检测，通过压力传感器来检测油烟的进口和出口的浓度，

通过检测装置把这个浓度的差反馈给电气控制装置，有电气控制装置来控制风机

和油烟净化设备，达到净化的效果。本设计的抽油烟机控制系统主要靠单片机进

行控制，通过软件设计来自动控制抽油烟机的开关，所以相对于普通的抽油烟机

来说，根据其自动检测功能，具有灵活性比较好，功耗低，便于操作等特点。而

本设计的油烟净化系统核心主要靠旋流净化设备产生的高速旋流，使油烟、废气、

异味吸排更彻底，油烟净化率更高。

ABSTRACT

This design not only have the basic switching function of the hood and kitchen

fumes generated in the process of cooking temperature and high and the gas leak of

low temperature characteristic, take different sensors, namely to high temperature,

pollution large flue gas using a digital temperature sensor detection, while the

temperature is low but greater risk of natural gas using gas sensor detection, when

the kitchen fumes or flammable harmful gases reach a certain concentration of value

by the sensor into the single chip microcomputer analysis, make motor circuit

automatically start and sound alarm, range hood promptly siphoned of harmful gases.

This design has a timer function, long setting in the work on the range hood. The

hardware part of the paper design of the range hood of the key input module, the

lampblack, the concentration of gas temperature detection module, display module,

the implementation of the circuit module, sound alarm module, the system software

part mainly in each module process has made the detailed analysis, the fumes from

the gas temperature, the concentration of the detection module, a detailed analysis,

the main program control, interrupt key scanning routines, display routines, interrupt

the alarm service program, in order to achieve the range hood automatic control

functions. Also analyzed the status of cooking fume pollution hazards and smoke

purification equipment, and also comes with a fume purification system. The fume

purification system design is to through traffic on the hood and the detection of

pressure by the pressure sensor to detect the concentration of fumes from the import

and export, this concentration difference is feedback to the electrical control devices

by detecting device, the electrical control device to control the fan and smoke

purification equipment, to achieve the effect of purification. The design of the range

hood control system mainly rely on single-chip microcomputer control software

designed to automatically control the switching of the range hood, relative to the

normal range hood, according to its automatic detection, flexibility, power low

consumption, easy operation and features. And the fume purification system, the
