本智能体温计采用AT89S52作为核心器件实现对系统的自动控制，采用双单片机串行处理结构。外界温度经AD590集成温度传感器采集，温度变化转换为线性电压信号，再经由OP07构成高精度低温漂的放大电路处理后，作为ADC0809的模拟输入信号，由ADC0809完成A／D转换，得到8位的数字信号送入单片机1（AT89S52）。单片机1将采集到温度值在LED数码管上显示出来，也通过串口通信将温度信号传到单片2（AT89S52）。-The intelligent thermometer AT89S52 as the key device used to achieve automatic control system, dual Serial processing structure. Outside temperature is collected by the AD590 integrated temperature sensor, the temperature change is converted to linear voltage signal, and then posed by the OP07 precision low temperature drift of the amplifier circuit disposed of, as the ADC0809 analog input signal, completed by the ADC0809 A/D conversion, are 8-bit The digital signal into the microcomputer 1 (AT89S52). MCU 1 in the collected temperature displayed on LED digital tube, but also by the temperature signals to serial communication chip 2 (AT89S52).
