文档介绍:摘要
本论文设计介绍了MCS-51系列单片机为控制芯片,对电热水壶工作进行控制的方法。通过电加热电路对水进行加热,并对水的温度进行采样,采样信号通过ADC0809将数字量送入单片机系统,经微机处理后,结合键盘控制实现LED显示,并可实现对水的温度的控制和超过水温的报警系统。
单片机控制热水壶的硬件构成包括8051芯片、8255芯片、地址锁存器等组成的单片机控制电路、温度检测电路、A/D转换电路、光电隔离电路、键盘及显示电路和温度加热电路。整个系统的关键电路是单片机控制电路,完成信号的输入和输出的转换,即可将温度检测电路采样的输入信号通过A/D转换器ADC0809进行处理加工后输出到显示器进行显示,并可以通过控制器控制温度,同时当水加热超过指定的温度以后,蜂鸣器工作报警。

Abstract
The thesis introducts the method of use the series of MCS-51 one-puter which is the control chip to control the work of kettle heat with electric energy. Through electric heated circle, the water will be heated, then sample the temperature of the water. The sampling signal will set the mimic to the system of single puter through ADC0809, after is processed by puter and controlled by the keyboard, it will be showed by LED monitor, at the same time, the system can control the temperature beyond the setting, the system of alarm will run.
The hardware of the one-puter controls the thermos which includes 8051 chips, 8255 chips, one-puter control circuit that address latch ,etc. make up temperature-measure circuit , circuit is changes by A/D, light-electricity and isolation circuit, keyboard and shows circuit、temperature heated circuit .The key circuit of the whole system is a control circuit of one-puter, finish the input and output of the signal conversion, can measure temperature sampled signal of input circuit which will deal with after processing then set to display and show to go on to outputting through A/D converter ADC0809, and can control the temperature through the keyboard, after heating and exceeding designated temperature in water, at the same time, the buzzer is sound so as to alarm.
Key word: One-puter Temperature control Controller
