System for assisting accurate parking of subway train at platform

Abstract

The invention relates to a system for assisting accurate parking of a subway train at a platform. The system comprises a master controller, a first sub-system and a second sub-system, wherein the first sub-system is used for assisting parking during manual driving of the train, the second sub-system is used for assisting parking during automatic driving of the train, the first sub-system and the second sub-system are connected to the master controller, the first sub-system comprises a speed reduction prompt device arranged on the platform, the speed reduction prompt device is used for displaying the optimal train speed of the train to a train driver, the second sub-system comprises a carried passenger mass measuring device arranged in a carriage, the carried passenger mass measuring deviceis used for measuring the carried passenger mass of the train and sending the carried passenger mass to an automatic train driving system, and the automatic train driving system controls the runningspeed according to the carried passenger mass of the train. Compared with the prior art, the system has the advantages that parking assistance in the manual driving mode and the automatic driving modeof the train can be realized, so that the parking precision of the subway train at the platform can be comprehensively improved.

Description

Technical field [0001] The invention relates to the field of urban rail transit, in particular to a system for assisting accurate parking of subway train platforms. Background technique [0002] Urban rail transit vehicles generally adopt automatic driving mode (ATO), which automatically realizes the traction and braking of the train, ensures the efficient operation of the train, and reduces the work intensity of the driver. At the same time, the platform of the station is basically equipped with a screen door system, which requires that the ATO system must be able to achieve accurate parking of the platform; similarly, when the train is manually driven, a certain degree of parking accuracy must be ensured. Passengers can board the train smoothly only by accurately aligning the train doors with the station screen doors. [0003] In actual stations, there are fixed waiting areas and drop-off areas at the platform screen doors. The drop-off areas are directly opposite to the center ...

AI Technical Summary

Problems solved by technology

[0005] At specific times, such as weekends, the subway operating company will arrange for the subway train driver to drive the train manually, but it is difficult to achieve accurate alignment of the train by manual driving, and it takes years of driving experience to achieve

If the driver does not have a good grasp of the speed of the train entering the station, it is easy to fail the designated parking position or drive the train out of the platform. These situations will cause delays in train operation and greatly affect the operation plan of the entire line
