智能油烟机控制电路
摘要：智能油烟机控制电路不仅具有油烟机基本的开关功能，而且还能根据厨房在烧菜做饭的过程中产生的油烟温度高，而泄漏的燃气温度低的特点，采取不同的传感器件进行检测。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的分析，使电机电路自动启动并发出声音报警，吸油烟机迅速将有害气体抽走。本设计还设有定时功能，可对抽油烟机进行时长的设定。论文的硬件部分主要设计了油烟机的烟气、燃气检测模块，按键输入模块，显示模块，执行电路模块等。智能油烟机控制电路主要靠单片机进行控制，通过软件设计来自动控制油烟机的开关，所以具有自动检测和智能控制的功能。

Intelligent Hood Control Circuit
Abstract: Intelligent Hood Control Circuit not only has lampblack machine basic switch function, and still can according to the kitchen is in the process of cooking oil produced in high temperature, the gas leak of low temperature characteristic, take different sensors detect thing. When the kitchen lampblack or flammable harmful gas reaches a certain concentration of value, the sensor into SCM analysis, make motor circuit automatically start and sound alarms, oil absorption rapidly take the harmful gas siphoned off. This design also is equipped with timing function, may to the smoke lampblack machine when carried out long setting. The paper mainly designed hardware components of smoke lampblack machine, gas detection module, key input module, timing display module, executive circuit module, etc. Intelligent Hood Control Circuit controlled mainly by MCU, through software designed to automatic control lampblack machine switches, so has the automatic detection and intelligent control function.
