摘　　要：设计了以美国DALLAS半导体公司的单总线温度传感器DS18B20为核心,以ATMEL公司的AT89C51为控制器的最简温度测量系统。介绍了系统的结构、硬件和软件,并给出了AT89C51与DS18B20通讯的部分汇编语言代码。与传统装置比,具有结构简单、抗干扰能力强、测量精度高、适用范围广等特点。In this paper,Mintemperature Measurement System （MTMS） is designed. The Single Bus Temperature Sensor DS18B20 Of us Semiconductor Company DALLAS and the AT89C51 of ATMEL Company are used in MTMS as kernel and controller respectively. This paper introduces the configuration,hardware and software of MTMS. Moreover,the assembler of communication between AT89C51 and DS18B20 is presented. Comparing with the traditional temperature control devices,this MTMS has the character of more simple structure, stronger anti -jamming ability, higher precision and wider application.
