[0002] A coupler is a hook at both ends of a train car or locomotive, which has the functions of connection, traction and buffering. A coupler is a vehicle component used to connect a locomotive and a vehicle or between vehicles, transmit traction and impact force, and keep a certain distance between vehicles. Before a train leaves the factory, the installation height of the coupler needs to be measured. The qualified height limit for coupler inspection is 880±10mm (according to the iron standard TB / T3044-2002TB / T3046-2002), that is, the height difference of couplers on the same vehicle shall not exceed 10mm. When the coupler height exceeds the allowable error range, the force-bearing area of ​​the hook tongue of the coupler connection will be reduced, thereby causing the natural separation of the coupler, resulting in a decoupling accident, endangering driving safety, and the consequences are unimaginable. It not only seriously threatens driving safety, but also causes serious losses to people's lives and property. At present, most of the measurements of coupler height are still carried out using measuring tools such as steel tape measures. Although this method is convenient, the measurement accuracy is not high enough.
