摘要
本文介绍一种新型嵌入式数字测温系统,该系统采用美国DALLAS公司生产的单总线数字温度传感器DS18B20为核心测温元件,以ARM7(LPC2132)为微处理器,给出了该系统的电路硬件设计与软件实现方法,并针对它在智能家居控制系统应用中出现的与硬件和软件有关的问题给出了解决方法。该系统具有结构简单、测温准确等特点,可作为一种新型的数字测温系统。
This paper designed a new type of embedded digital measuring temperature system, using ARM7（LPC2132） as microprocessor and DS18B20 as main temperature transducer. We gave some answers about hardwares and short to this system when using it in intelligent home control system. The character of DS18B20 and notices in using was introduced , the hardwares design and pivotal programme code was given, it＇s configuration is simple,it cam measure temperature exactly, and it is a new type of embedded digital measuring temperature svstem.
