摘 要 室内环境的检测和控制在一些生产制造行业起着举足轻重，广泛应用于社会生活的各个领城,适用于家电、食品、汽车、材料、电力电子等行业,尤其在石油、化工、电力、冶金等重要工业领域,对环境的控制中以温度控制为主，以下就是针对温度的检测控制为例进行阐述。在工业生产中，对温度的测量和监控是非常重要的一个环节,对于保证产品生产质量具有重要的现实意义.所以生产出一个便携的、灵活、操作简单、功能强大的环境监测系统具重要的意义. 本设计以ARM LPC2103为核心的室内环境控制系统的工作原理和设计方法。ARM LPC2103开发板具有丰富的硬件资源。而室内环境的控制主要是以温度控制为主，所以本文就以温度控制系统为例来进行说明。温度信号由温度芯片DS18B20采集，并以数字信号的方式传送给ARM。 文中介绍了该控制系统的硬件部分，包括：温度检测电路、温度控制电路、PC机串口通讯ARM LPC2103 开发板为基础进行了测试，运行正常，功能符合设计要求。 关键词： 室内环境； ARM LPC2103； DS18B20； 温度检测； 温度控制 Abstract Detection and control of the indoor environment in the manufacturing industry plays an important , widely used in various fields of social life , applies to household appliances, food , automotive , materials , power electronics and other industries , especially in the important industrial areas ,such as petroleum , chemical , electric power , metallurgy , etc. The control of the environment focuses on temperature control, the following is described to temperature measurement and control , for example . In industrial production , measurement and monitoring of the temperature is very important , has important practical significance to ensure the quality of products . So it has important significance to produce a portable , flexible, simple , powerful environmental monitoring system . This design is based on ARM LPC2103 as the core of the working principle and design method of the indoor environment control system .ARM LPC2103 development board has rich hardware resources .The control of the environment focuses on temperature control, so this paper take the temperature control system for example to indicate. The temperature signal is collected by the temperature chip of DS18B20 and is sent to the ARM in the way of digital signal. This paper introduces the hardware part of the control system , including temperature detection circuit , the temperature control circuit , the PC with ARM serial communication circuit and a number of interface circuits . ARM takes the signal to correspondingly pr
