The invention discloses a continuously welded track steel rail displacement crawling vehicle-mounted detection system and method based on a vernier caliper principle, the system comprises a measuring scale, a carrying platform, an imaging module and a data processing module, the measuring scale forms a reference system and a reference system which are parallel on a steel rail and on one side of the steel rail; the measuring scale forms marks on the reference system and the reference system so that the camera unit of the imaging module can locate and mark the target position to measure the creeping value of the steel rail. The vernier scale is laid at the bottom of the steel rail, the main scale is laid on the steel rail, when the steel rail generates displacement during crawling, high-precision steel rail crawling measurement can be achieved according to the working principle of the vernier caliper and the positions calibrated by the main scale and the vernier scale in real time, and the steel rail crawling measuring device has the outstanding advantages of being easy to install, convenient and fast to use, accurate in measurement, low in cost and the like. And the steel rail crawling displacement can be measured at any position of a line.

    本发明公开了一种基于游标卡尺原理的无缝线路钢轨位移爬行车载检测系统及检测方法,包括测量尺、运载平台、成像模块和数据处理模块,所述测量尺,其分别在钢轨上和钢轨一侧形成平行的基准系和参照系;所述测量尺通过在基准系和参照系上形成标识以供所述成像模块的所述相机单元定位标识目标位置以测得钢轨的爬行值。通过将游标尺铺设在钢轨底部,并将主尺铺设在钢轨上,在钢轨爬行产生位移时,利用游标卡尺的工作原理对照主尺和游标尺实时校准的位置,可以实现高精度钢轨爬行测量,具有安装简单、使用便捷、测量精准、成本低等突出优点,可在线路任意位置测量的钢轨爬行位移量。
