为提高高速铁路轨道监测系统的实时性和可维护性, 采用基于 Thread的无线传感网络实现轨道状态的实时采集、汇聚和远程传输。采用时间同步休眠控制策略和基于阈值的数据采集策略以提高监测系统的可靠性。通过系统仿真、网络的性能测试, 该系统能对高速铁路轨道状态进行实时有效监测, 对轨道安全和铁路运输有现实意义。

In order to improve the real-time performance and maintainability of high-speed railway track monitoring system, a thread-based wireless sensor network is utilized to realize real-time acquisition, aggregation and remote transmission of track status. Time synchronization sleep control strategy and threshold-based data acquisition strategy are adopted to improve the reliability of the monitoring system. Through system simulation and network performance test, the system can monitor the rail status of high-speed railway in real time and effectively. This work has practical significance for rail safety and railway transportation.
