The invention discloses a steel rail crawling online monitoring terminal, system and method. The monitoring terminal comprises a camera assembly, an image processing unit, a signal acquisition unit, a communication unit, a temperature measurement sensor and a light source. The camera assembly shoots an image containing a measurement identifier, and the image processing unit calculates position information of the measurement identifier according to the image shot by the camera assembly and then sends the position information to the signal acquisition unit. The light source is used for supplementing light for image shooting of the measurement identifier through triggering of the signal acquisition unit under a weak light condition. And the signal acquisition unit simultaneously acquires a steel rail temperature signal measured by the temperature measurement sensor, and sends the steel rail temperature signal and the position information of the measurement identifier to the outside through the communication unit. The technical problems that an existing line steel rail state monitoring system is installed and measured in a contact mode, potential safety hazards to a line are large, and maintenance is difficult can be solved.

    本发明公开了一种钢轨爬行在线监测终端、系统及方法,监测终端包括:相机组件、图像处理单元、信号采集单元、通讯单元、测温传感器及光源。相机组件拍摄包含测量标识的图像,图像处理单元根据相机组件拍摄的图像解算出测量标识的位置信息后将其发送至信号采集单元。光源用于弱光照条件下通过信号采集单元的触发为测量标识的图像拍摄进行补光。信号采集单元同时采集测温传感器测得的钢轨温度信号,并将钢轨温度信号及测量标识的位置信息通过通讯单元对外发送。本发明能解决现有线路钢轨状态监测系统采用接触式安装、测量,对线路存在安全隐患大,以及维护困难的技术问题。
