Problems solved by technology

[0003] At present, non-contact detection devices have been researched at home and abroad, as the future direction of obstacle detection, but due to the limited existing technology and insufficient reliability, it cannot be widely used. At the same time, considering the characteristics of urban rail transit, that is The speed of the train is within the range of 0-100km / h, and the reliability of the non-contact detection method is lacking. Consider using a contact detection device to highlight its reliability. When encountering a light obstacle, the detection device can pass a slight collision The obstacle pops out of the running rail surface, and when it encounters a heavy obstacle, the normal trigger mechanism can be activated to trigger the train to brake to avoid accidents or deterioration

Abstract

In order to solve the problem of obstacle collision in on-orbit operation of an urban rail transit train and prevent accidents caused by collision, the invention provides a device and a method for coping with obstacle collision and detection, which meet the requirement of safe running of a subway train. The device adopts a contact obstacle detection mode. Small obstacles are removed through light collision, train running is not affected, large obstacles are detected through heavy collision, train braking is effectively triggered, and accidents or deterioration are restrained in time.

Description

technical field [0001] The invention relates to the technical field of urban rail trains, in particular to an obstacle detection method for urban rail trains. Background technique [0002] With the acceleration of urbanization, the demand for urban transportation continues to increase, and urban rail transit is playing an increasingly important role in the field of public transportation. With the development of urban rail transit, considering the needs of efficient operation and safety, obstacles on the operating line are extremely harmful. When encountering obstacles, destructive collisions may occur, and major accidents such as derailment may occur. Therefore, On-orbit obstacle detection research becomes necessary. [0003] At present, non-contact detection devices have been researched at home and abroad, as the future direction of obstacle detection, but due to the limited existing technology and insufficient reliability, it cannot be widely used. At the same time, consi...
