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

The present invention is to solve the obstacle collision problem of urban rail transit trains running on the track. In order to prevent accidents caused by collisions, the present invention proposes a device for dealing with obstacle collisions and detection that meets the needs of safe running of subway trains. The device adopts The contact obstacle detection method removes small obstacles through light collisions without affecting the running of the train, and detects large obstacles through heavy collisions, effectively triggering train braking, and timely curbs the occurrence or deterioration of accidents.

Description

technical field [0001] The invention relates to the technical field of urban rail trains, in particular to an obstacle detection device for urban rail trains. Background technique [0002] With the acceleration of urbanization, the demand for urban transportation continues to increase, and urban rail transit plays an increasingly important role in the field of public transportation. With the development of urban rail transit, taking into account the needs of efficient operation and safety, obstacles on the running line are extremely harmful. When obstacles are encountered, destructive collisions will occur at light, and major accidents such as derailment will be caused at worst. Therefore, On-orbit obstacle detection research becomes necessary. [0003] At present, non-contact detection devices have been developed at home and abroad as the future direction of obstacle detection. However, due to the limited existing technology and insufficient reliability, they cannot be wid...
