摘要
信息技术的高速开展和广泛应用给人类带来了革命性的进步，随之渗透到人们日常活动的
方方面面。因此各种计算机、效劳器机房也如雨后春笋般涌现。大量维护工作也由此产生。
对于机房的日常管理和维护最重要的就是平安问题。而其中最为突出的问题之一就是防火。
本次毕业设计的主要目的就是设计一个基于温度监测的火灾报警系统。本人采用理论探讨与
实际开发相结合的方法，研究了美国 DALLAS 公司开发的一线总线技术及其通信协议。并
以美国 DALLAS 公司的一线总线技术为核心，连同单片机技术，将火灾报警的温度监测环
节予以实现。并且依据该理论，设计出一个廉价、实用的温度监测系统。
关键词：一线总线 DS1820 AT89C51
Abstract
The high-speed development and wide application of information technology has brought
revolutionary progress to and influenced human beings. As the result, the emerged puter&server
room arouses serious daily maintenance.The fire fighting is one of them to the puter&server room.
The aim of this paper is to design one auto-alarm system based on the temperature supervision.By
means of bining theory discussion arid practical development, the author studied the 1-wire bus
technology developed by the Dallas Semiconductor pany in USA. At the same time, the author
realized the temperature supervision as one part of the auto-alarm system based on DALLAS 1-wire
bus technology and MCU. Also, the author engineered and designed one on-line and cheap
temperature supervision system.
Keywords： 1-wire bus, DS1820， AT89C51
