中文摘要：

传统的温度测量采用有线测量方法,只能对近距离待测区域进行测量。信号的长距离传递导致造价昂贵、信噪比低、线路复杂等问题。针对以上问题,本文设计了一个基于ARM的无线传感器网络系统,可以测量不同地点的温度及无线组网,观测者可以在离待测区域较远的地方同时监测多个地点的温度。此无线测温系统经过性能测试,证明其具有信号测量精度高、传输距离远、造价低等优点。

英文摘要：

Wire measurement is used in traditional measurement of temperature,and it just can measure some close quarters. Many problems occur in long distance transmission of signal,such as expensive cost,low signal noise ratio and complex circuitry. To solve these problems,ARM-based wireless sensor network system is developed in this paper. It has the functions of both measuring temperature of different areas and forming wireless networks. What ＇s more, observers can inspect temperature of many different areas far away from the measuring place. The advantages of precise signal measurement,long transmitting distance and low cost are standing out after testing the performances of the wireless measuring system.
