[Other resource] 51asn DL : 0: 设计的温度采集模块是应用一个滑动变阻器通过改变电阻值进行模拟的温度值改变情况；模数转换模块是运用ADC0809芯片进行模数的转换，把采集到的模拟电压值变为数字值；单片机控制系统通过程序判断此数字值的大小，这样控制温度报警模块，一方面控制发光二极管的亮灭情况，另一方面控制蜂鸣器的报警；温度显示模块应用四位数码管显示模拟的温度值。因此，构成了此模拟的温度控制系统。本系统主要实现了模拟的温度值在30到60的一个设定范围内，正常显示温度，一旦超过了此范围，就会有报警。-design of the temperature acquisition module is the application of a sliding rheostat by changing resistor value simulated temperature change ; analog-to-digital conversion module Connection between ADC 0809 chip is used for the conversion module, Acquisition to put the value into voltage simulated digital value; SCM control system through the procedures to judge the value of this size figures, This temperature alarm control module, on the one hand to control the LED-destruction, the other to control the buzzer sounded alarm; Temperature Display Module application of four digital simulation shows that the temperature value. Therefore, this constitutes a simulation of the temperature control system. The system achieved a simulation of temperature from 30 to 60 in the context of a set, showe
