Radio frequency awakening-based rail detection wireless sensing system and control method

The invention provides a rail detection wireless sensing system based on radio frequency awakening and a control method. The wireless sensing system comprises wireless sensing nodes arranged on a rail, an awakening source arranged on a train and a receiver arranged in a train control center. Compared with a traditional detection system, the rail detection wireless sensing system provided by the invention has the advantages of real-time monitoring and labor cost saving. Due to the fact that the energy storage battery is added, the wireless sensing node is more stable and reliable compared with the mode that energy is collected in a single mode to maintain work. And the wake-up mode is an external energy injection mode, so that the power consumption is greatly reduced. 本发明提出一种基于射频唤醒的铁轨检测无线传感系统及控制方法，所述无线传感系统包括布设在铁轨上的无线传感节点，布设在火车上的唤醒源和布设在火车控制中心的接收器。本发明提出的铁轨检测无线传感系统相比与传统的检测系统，具有实时监测、节约人工成本的优点。由于加入了一块储能电池，相较于通过单一方式收集能量来维持工作的无线传感节点更加的稳定可靠。并且唤醒方式为外界能量注入的方式，大大的降低了功耗。
