Control system for distribution valve of brake system of storage battery power engineering truck

Abstract

The invention discloses a control system for a distribution valve of a brake system of a storage battery power engineering truck, belonging to the control field of the brake system in the storage battery power engineering truck. The control system comprises an electronic distribution valve closed loop control system, a reserve air distribution valve control system and a hard braking fast pressurizing control system, wherein the electronic distribution valve closed loop control system is started under the normal condition; the reserve air distribution valve control system is started when the electronic distribution valve closed loop control system fails; and the hard braking fast pressurizing control system is used under the emergent condition. In the invention, closed loop control is carried out on the braking cylinder of the storage battery power engineering truck through controlling the pressure of a wind cylinder in advance, so that the control precision of the braking cylinder pressure can be greatly improved; the reliability of the brake system can be improved through using a reserve air distribution valve; and an emergent braking fast pressurizing passageway can ensure that the emergent braking action can be generated in a short time under an emergent circumstance, thus the safety of the storage battery power engineering truck can be guaranteed.

Description

technical field [0001] The invention mainly relates to the control field of the brake system in the battery electric engineering vehicle, in particular to a control system for the distribution valve of the braking system of the battery electric engineering vehicle. Background technique [0002] With the development of modern railway technology, higher requirements are put forward for the safety and control accuracy of the braking system of subway engineering vehicles. The safety and control precision of the brake system of battery electric engineering vehicle. At present, the brake and release commands in the existing battery electric engineering vehicle braking system are controlled by air transmission open loop, resulting in slow response and low control accuracy of the braking system; all use a single pure air distribution valve system, and there is no backup system , The reliability of the system is poor: the emergency braking uses the total air to directly fill the br...
