Title:
RAILWAY VEHICLE FRONT-END DYNAMIC GAUGE ACQUISITION METHOD AND ADDITIONAL ANTI-COLLISION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/011821
Kind Code:
A1
Abstract:
Disclosed in the present invention are a railway vehicle front-end dynamic gauge acquisition method and an additional anti-collision system. A transverse reduction amount that is calculated by each calculation point of each vehicle front-end contour with respect to a gauge reference line and an included angle of cutting lines are drawn to form a dynamic gauge of an operation front section of a vehicle. The additional anti-collision system comprises an additional anti-collision mechanism, an anti-collision control system main unit, a vehicle-mounted signal system and a power supply system, wherein the additional anti-collision mechanism comprises a pilot beam and a telescopic drive unit connecting the pilot beam and a vehicle; and the anti-collision control system main unit obtains a vehicle front-end dynamic gauge, and instructs, according to the obtained vehicle front-end dynamic gauge, the pilot beam to move forwards by a first distance and a side-wing telescopic pilot beam to extend backwards by a second distance, the first distance and the second distance being respectively located in the vehicle front-end dynamic gauge. The present invention makes a vehicle have the optimal anti-collision buffer capability at the front thereof, and a side-wing obstacle can also be prevented from colliding with an apparatus at the bottom of a front section of the vehicle.
