针对管道泄漏监测的应用场景，提出了一种管道泄漏远程实时检测的方案，其特点是结合GPRS网络和分簇结构的WSN实现远距离的数据传输。设计了一种由传感器节点、集中节点和汇聚节点协同工作的无线传感器监测网络，并提出了适用于管道泄漏监测的多层次分簇路由协议、MAC层防数据碰撞机制和基于RTC时间的数据同步采集机制。该系统能够正确、稳定地完成数据采集，并达到了低功耗的设计目标，满足实际检测需要。

For the application of gas pipeline leakage remote monitoring, this paper proposes a design of Gas Pipeline Leakage Remote Monitoring System which implements long-distance wireless communication between WSN nodes and control room by combining GPRS network with cluster-based wireless sensor network. In this design, wireless monitoring network consists of sensor nodes, sink nodes and concentrator nodes. The multi-level clustering routing protocol and the MAC protocol based on IEEE802.15.4 and RTC-based time synchronization are adapted to the system. The Gas Pipeline Leakage Remote Monitoring System is not only able to complete data acquisition correctly and stably, but also achieves the low power design goals.
