PC机与单片机温度检测系统的设计与实现

Design and Implementation of Surveillance System Using PC and Single-chip Microcomputer

选用ATMEL公司的AT89C51单片机及DALLAS公司的DS18B20智能温度传感器作为核心元件,设计温度检测模块电路,并且为温度检测模块设计了相应的通信接口电路,使之能够方便地连接到远程PC机终端;实现了在PC机端采用VC++6.0编制的程序将接收到单片机传递的数据进行显示以及曲线的绘制.

In this paper a temperature detection module,with the AT89C5 microcomputer of ATMEL and DS18B20 of D.AUAS company as the core components was designed. An associate communication interface was also designed which makes it more convenient to access to remote PC terminals. The VC ＋ ＋ 6.0 program on PC will finish the display of data transmitted by MCU and the drawing of desired curve.
