基于单片机的环境监控系统.doc

摘要 随着现代社会的发展，测量涉及到工农业生产、国防建设、科学试验、国内外贸易、人民生活等各方面，是国民经济的一项重要的技术基础。所以对标准计量室环境要求越来越高。为了更好的对标准计量室环境进行控制，传统的人工控制已经不能达到要求。?这就需要一种新的标准计量室环境控制系统?，可以准确的对计量室的温度，湿度进行检测与控制 本设计主要介绍了一种新型标准计量室环境控制系统的功能、检测和控制方法、硬件系统及其软件。该套环境控制系统适用于计量室等对温度湿度有严格要求的场合，可广泛适用于我国东北地区等气候干燥地区，用来检测与控制室内温度与湿度。 本系统采用单片机为核心元件，对室内温湿度进行检测与控制，并能实现火灾报警，具有结构简单，工作稳定，可靠性高，使用方便等优点。 关键词：环境控制系统 温度传感器 湿度传感器 单片机 Abstract With the development of modern society, measurement related to industrial and agricultural production, national defense construction, scientific experiments, domestic and foreign trade, the peoples living standards, and other areas, the national economy is an important technological base. Therefore, the standard Measurement Room environmental requirements getting higher and higher. In order to better control of the standard Measurement Room environment , the traditional manual control can not meet the requirement. This requires a new standard measurement room environmental control systems,accurate for Measurement Room temperature and humidity to Detection and control. This design introduces a new standard Measurement room environment controlling system function, detection and control methods, hardware and system software. the environmental control system Applicable for standard Measurement Room temperature and humidity of the strict requirements of occasions. Can be widely applied in Chinas northeast region, Dry areas, to Detection and control the indoor temperature and humidity. The system uses single-chip microcomputer,as the core components of the indoor temperature and humidity to detect and control, fire alarm and to achieve, is simple in structure, work stability, high reliability, ease of use advantages. Keywords : environment controlling system temperature sensor humidity sensor single-chip microcomputer 目录 摘要 I Abstract II 第1章 绪论 1 1.1选题背景与研究意义 1 1.1.1标准计量室 1 1.1.2标准计量室对环境的要求 1 1.1.3本课题重点工作 2 1.1.4温湿度检测技术 2 1.2标准计量室环境控制系统的概述 2 1.2.1 系统的功能与特点 2 1.2.2系统主要技术指标 3 1.2.3系统的主要
