摘要
单片机技术已经普及到我们生活,工作,科研,各个领域,已经成为一种比较成熟的技术本文将介绍一种基于单片机控制的数字温度器,本温度计属于多功能温度计,可以设置上下报警温度,当温度不在设置范围内时,可以报警。随着现代工农业技术的发展及人们对生活环境要求的提高,人们也迫切需要检测与控制温度。本文通过采用蜂鸣器作为电声元件的温度报警器的设计,阐明了该装置进行设计与制作的具体过程及方法。这种温度报警器结构简单,可操作性强,应用广泛。工作时,温度测量范围为538C。当前环境温度若超过设定的高温临界温度,由单片机发出报警信号,从而防止带来的不必要的损失。造成高温火灾有:电气线路短路、过载、接触电阻过大等引发高温或火灾;静电产生高温或或火灾;雷电等强电侵入导致高温或火灾;最主要是机房内电脑、空调等用电设备长时间工作,导致设备老化,空调发生故障,而不能降温;因此机房内所属的电子产品发热快,在短时间内机房温度升高超出设备正常温度,导致系统瘫痪或产生火灾,这时温度报警系统就会发挥应有的功能。关键词STC89C51单片机,数字控制,温度计,DS18B20,AT24C02
