The invention discloses a real-time detection and alarm system and method for foreign matters on a railway track bed, belongs to the technical field of railway track bed inspection, and solves the problems of high inspection cost, large processing data volume and poor real-time performance of an inspection result in an inspection technology based on image processing. According to the technical scheme, the line scanning laser sensor is adopted to inspect the subway track bed, the MCU chip sends a collecting and reading asynchronous time sequence to control the line scanning laser sensor to collect height data of the subway track bed, and whether the height data in a data set is larger than a safe height limit value of the track bed or not is checked to judge whether the track bed has foreign matter or not; controlling the linear scanning laser sensor to perform cross data acquisition through an acquisition and reading asynchronous time sequence, and performing anti-cross reading on the data acquired by the linear scanning laser sensor; the scanning height data loss or distortion caused by scanning light superposition interference between the line scanning laser sensors is avoided, the real-time performance of the collected data is guaranteed, complex image data does not need to be processed, the timeliness is high, the overall structure of the system is simple, and the inspection cost is low.
一种地铁道床异物实时检测告警系统与方法,属于铁路道床巡检技术领域,解决基于图像处理的巡检技术存在的巡检成本高、处理数据量大、巡检结果实时性差的问题;本发明的技术方案采用线扫激光传感器对地铁道床进行巡检,通过MCU芯片发送采读异步时序控制线扫激光传感器对地铁道床的高度数据进行采集,检查数据集中高度数据是否大于道床安全高度限值来判断道床有无异物;通过采读异步时序控制线扫激光传感器交叉采集数据,且反交叉读取线扫激光传感器采集的数据;避免线扫激光传感器之间因扫描光线叠加干扰而产生的扫描高度数据丢失或者失真,保障采集数据实时性,本发明无需处理复杂的图像数据,时效性高,系统整体构简单,巡检成本低。
