摘要
针对常规多点温度测量显示系统的缺点与不足，设计出以89C51单片机为主控器的全数字化多点温度测量显示系统．本系统采用模数转换芯片AD574巡回采集现场的多点温度信号，经过数字滤波、标度变换等处理过程，最后将处理后的数字量送到液晶显示器上分时显示各点的温度值．
With 89C51 monolithic processor as main controller, a digital temperature measuring display system is designed to overcome the shortcoming of regular temperature measuring display system. This system applies AD 574 to collect the on - spot temperature signal. Through the process of filtration and scale transformation, the processed digits are sent to the display device, representing the temperature value of different spots at different time.
