The invention relates to a wireless turnout switch rail fracture monitoring pre-alarm system which is characterized by comprising a switch rail (1) to be detected, a fracture sensing unit (2), a collector (4), a data gateway (10), monitoring software (11) and a protective clamping plate (12). The fracture sensing unit (2) is installed on the switch rail (1) and used for detecting structural health state information of the switch rail (1). A collector (4) and a data gateway (10) are installed near the monitoring area (13), and detection data of a sensing node (16) formed by the fracture sensing units (2) are sent to the nearby data gateway (10) through the short-distance wireless communication technology; the turnout switch rail fracture pre-alarm monitoring system can effectively monitor the phenomena of original damage, nuclear damage or contact fatigue crack expansion and even rail breakage of a turnout switch rail under the action of long-term fatigue load.

    本发明涉及一种无线道岔尖轨断裂监测预报警系统,其特征是:包括:待测尖轨(1)、断裂传感单元(2)、采集器(4)和数据网关(10)、监测软件(11)、防护夹板(12);断裂传感单元(2)安装在尖轨(1)上,用于检测尖轨(1)的结构健康状态信息;在监测区(13)域附近安装采集器(4)和数据网关(10),通过近距离无线通信技术将断裂传感单元(2)构成的传感节点(16)的检测数据发送给附近数据网关(10);这种道岔尖轨断裂预报警监测系统,以便能有效的监测道岔尖轨在长期疲劳载荷作用下的原始伤损、核伤或接触疲劳裂纹的扩展甚至断轨现象。
