A traction braking control method, system and device for a rescue vehicle

Abstract

The invention discloses a traction braking control method for a rescue vehicle. Considering that rescue vehicles with different weights have different traction forces and braking forces corresponding to starting and stopping under the same coupler pair of pulling forces, this application is based on rescue vehicles. The weight of the whole vehicle corresponding to the car applies traction and braking force to the rescue vehicle, the purpose is to apply traction and braking force to the rescue vehicle under the opposite tension that the coupler can bear, thus reducing the opposite tension on the coupler to a certain extent, The risk of coupler breakage and train safety issues are avoided. The invention also discloses a traction braking control system and equipment of the rescue vehicle, which have the same beneficial effect as the above traction braking control method.

Description

technical field [0001] The invention relates to the field of rail transit circuit control, in particular to a traction braking control method, system and equipment for a rescue vehicle. Background technique [0002] At present, when an urban rail vehicle fails, in order not to affect the operation of other trains, it is necessary to carry out fault rescue for the urban rail vehicle. In the prior art, the traction braking control method of the train used to rescue urban rail vehicles under the rescue condition is as follows: in order to shorten the rescue time, when the train is in the rescue traction condition, the traction device of the train applies traction with the maximum traction force; When the train is in the rescue braking condition, the brake device of the train applies the brake with the maximum braking force; and there is no delay time for the conversion of the train traction and braking. However, when the train is converted from the rescue traction working cond...

AI Technical Summary

Problems solved by technology

However, when the train is converted from the rescue traction working condition to the rescue braking working condition, the coupler of the train is subjected to a large counter-pull force, even close to or exceeding the bearing force of the coupler itself, which leads to the risk of breakage of the coupler, which is the cause of the train failure. Rescue raises safety concerns
