基于无线传感网络的温度监控系统设计
摘 要
近年来，随着无线通信技术和传感器技术的飞速发展，无线传感器网络越来越得到广泛的应用，特别是在环境监测、智能家居、工业监控等领域的应用。基于无线传感器网络的温度监控系统用于对温度的自动监控。
无线传感器网络是由一组传感器以Ad Hoc方式构成的无线网络，其目的是协调地感知、采集和处理网络覆盖的地理区域中感知对象的信息，并发布给监控者。随着通信技术、嵌入式计算技术和传感器技术的飞速发展和日益成熟，具有感知能力、计算能力和通信能力的微型传感器开始在世界范围内出现，由这些微型传感器构成的传感器网络引起了人们的极大关注。这种无线传感器网络综合了传感器技术、微机电系统技术、分布式信息处理和网络通信技术，能够协调地实时监测、感知和采集网络分布区域内的各种环境或监测对象的信息，并对这些信息进行处理。在信息采集及处理的过程中，涉及到了基于嵌入式系统及面向片上系统的平台设计，基于微机电系统技术(MEMS)的传感器研发，针对分布式系统的数据挖掘及队列数据处理，以及具有自适应组网和自主路由的无线网络协议及其安全问题。正是对这些课题的不断探索，促成了无线传感器网络研究的各个分支的产生以及标准的制定。
本文是设计一个基于无线传感网络的温度监控系统其中包括温度的采集、无线发射、无线接收、报警等内容的设计可以广泛应用于工业监控、智能楼宇、环境监测等领域

Abstract
In recent years, with the rapid development of wireless communication and sensor technology, wireless sensor networks has been widely used, especially in the field of environmental monitoring, smart home, and industrial monitoring applications.
Wireless sensor network is constituted by a group of sensors to the Ad Hoc mode wireless network, and its purpose is to coordinate perception, acquisition and processing of the geographical area covered by the network-aware object, and issued to the observer. With the rapid development of communication technology, embedded computing and sensor technology and increasingly sophisticated, with perception, computing power and communication capabilities of the tiny sensors worldwide, aroused by these miniature sensors, sensor networks of great concern. This wireless sensor network integrated sensor technology, MEMS technology, distributed information processing and network communication technology, able to coordinate a variety of environmental monitoring object information in real-time monitoring, sensing and collecting network distribution area, and these information processing. In the process of information collection and processing related to a platform-based system embedded systems-oriented on-chip design, micro-electromechanical systems (MEMS)-based sensor development for distributed systems, data mining and queue data processing and adaptive networking and routing wireless network protocols and security issues. It is the continuous exploration of these topics, contributed to the generation of the various branches of the wireless sensor network, as well as the development of standards.
This article is to design a wireless sensor network-based temperature monitoring system, including the design of the temperature of the collection, wireless transmitter, wireless
receiver, alarm and other content can be widely used in industrial monitoring, smart buildings, environmental monitoring field
