摘要
无线传感器网络综合了传感技术、MEMS技术、无线通信技术和分布式信息处理技术等,能够通过各类集成化的微型传感器,实时、全方位地监测被测对象的信息,通过嵌入式系统对信息进行处理,并通过自组织无线通信网络,以多跳中继方式将所感知信息传送到终端。利用无线传感器网络可以很好地实现对青藏铁路冻土区的无人实时监测和无线数据传输,可以对冻土区铁路工程进行长期、全面、系统的观测,确保青藏铁路安全运营,并对铁路长期运营、维修和养护提供科学依据。
Integrating technology in fields such as sensing,MEMS,wireless communication and parallel information processing,wireless sensor networks （WSNs ）can easy realize the purpose of temperature monitoring totally in real time through integrate micro sensors. After information is acquisited,the embedded module processes the signals and then the data is sent out to the terminal through serf-organized wireless networks. WSNs are very suitable for unmanned monitoring frozen soil region along the Qinghai-Tibet railway in real time. In this way,the Qinghai-Tibet railway will be under long time,all round,systematic monitoring. Thus,this system will ensure the safety of the Qinghai-Tibet railway and besides,it can also provide scientific basis for the maintenance of the Qinghai-Tibet railway.
