摘　　要：利用PT100铂电阻作为传感器搭建电桥电路,提取温度变化信号。温度信号经放大后送入16位A/D转换器LTC1864进行采样,变成数字温度值。选用Atmega16微处理器作为检测控制核心,将数字温度值再次滤波和线性化处理,实现高精度温度测量与控制。整个设计过程借助Proteus实时仿真调试,逼真地再现了设计思想,大大缩短了设计调试周期。PT100 platinum resistance is used to build a bridge circuit for the sensor to extract the changing temperature signal.After being amplified,the temperature signal is sent to the 16 bit A/D converter LTC1864 for sampling and transferring a digital temperature value.Atmega16 microprocessor is selected as the core of detection and control,and the digital temperature value is filtered and linearized again to achieve high-precision temperature measurement and control.In the whole design process,Proteus real-time simulation debugging is used to vividly reproduce the design idea and greatly shorten the design debugging cycle.
