资产监控，特别是配水管道等基础设施监控，对于因网络老化而面临新挑战的公用事业所有者来说变得越来越重要。仅在英国，2009 年至 2010 年期间，就有约 3281 兆升 (10(6)) 的水因水管故障或泄漏而被浪费。可以使用多种技术来监测配水管网。本文介绍了基于塑料管道中相对间接压力变化的测量的智能无线传感器网络的设计、开发和测试，该网络用于水管道泄漏检测。每 6 小时测量一次，传感器节点的功耗最小化至 2.2 μW，以延长网络的使用寿命，并提高传感器节点与当前能量收集方法和长寿命电池可用功率水平的兼容性。通过实验室和现场试验研究了一种新型压力传感方法的性能和功能。传感器能够测量泄漏引起的压力变化。这些压力分布也可用于定位泄漏。
Asset monitoring, specifically infrastructure monitoring such as water distribution pipelines, is becoming increasingly critical for utility owners who face new challenges due to an aging network. In the UK alone, during the period of 2009-2010, approximately 3281 mega litres (10(6)) of water were wasted due to failure or leaks in water pipelines. Various techniques can be used for the monitoring of water distribution networks. This paper presents the design, development and testing of a smart wireless sensor network for leak detection in water pipelines, based on the measurement of relative indirect pressure changes in plastic pipes. Power consumption of the sensor nodes is minimised to 2.2 mu W based on one measurement every 6 h in order to prolong the lifetime of the network and increase the sensor nodes' compatibility with current levels of power available by energy harvesting methods and long life batteries. A novel pressure sensing method is investigated for its performance and capabilities by both laboratory and field trials. The sensors were capable of measuring pressure changes due to leaks. These pressure profiles can also be used to locate the leaks.
