摘要
以单片机AT89S52为控制芯片,利用Delphi作为上位机控制软件,通过串口与单片机通信控制单总线上各个DS18B20采集温度的方法,实现了单总线DS18B20数字传感器多点在线监测及数据库存储。
Through taking AT89S52 MCU as the control chip and Delphi as control software for the host computer and making use of RS232 serial communication technique,the multi-point online monitoring and database storage based on DS18B20 digital sensor with single bus were realized.
