Description

Technical Field

[0001] The utility model relates to the technical field of railway vehicles, in particular to a driving train alignment accuracy measuring device. Background Art

[0002] The physical parking position mark specifies the parking position of the subway train and is a reference criterion for the subway train driver to park the train according to the mark. The subway train driver aligns the physical parking position mark with the side window of the driver's cab to determine whether the passenger compartment door is opened within the permitted range after the train stops at the station.

[0003] In daily operation, the manual driving of subway trains uses ground scale lines for benchmarking accuracy measurement. The ground scale lines are benchmarked with reference to the markings on the driver's cab side door floor. Each type of vehicle is of varying quality. Due to the uneven level of manual driving, after the manual driving trains are benchmarked, some use the approximate difference between the driver's cab side window and the physical mark of the parking position as the measurement value, while others use the ground scale on the platform side and the markings on the driver's cab side door floor as the measurement value. However, the ground scale standard has a large span, and the measurement results of both methods are accurate, but also lack more precision. The quality of benchmarking will cause different levels of travel experience for passengers and even affect the efficiency of passengers getting on and off the train.

[0004] Therefore, in view of the shortcomings of the prior art, a device for measuring the alignment accuracy of a driving train is provided. Utility Model Content
