Abstract

The invention discloses a synchronous control circuit for rail-vehicle-rescue emergency braking. Normally-closed contact coupling a relay and emergency braking relays are parallelly connected into emergency-braking train-line loops of lead vehicles of rescue vehicles and failed vehicles, and are used for rebuilding the emergency-braking train-line loops after rescue trains and failed trains are coupled; meanwhile, braking isolating switches are arranged on the lead vehicles of the rescue vehicles and the failed vehicles, rescue head-and-tail relays and braking isolating relays are parallelly connected, emergency-braking-button normally-closed contact of a driver table is connected into the emergency-braking train-line loops in a series mode, braking isolating electromagnetic valves of all the vehicles are parallelly connected into an emergency train-line loop, power is supplied through the emergency train-line loop, the emergency train-line loop is controlled to control the braking isolating electromagnetic valves, and under the working condition that rescue is achieved, emergency-braking synchronous control is achieved. A control method is safe and reliable, the synchronism is accurate, the purchasing expense of a whole project is saved more than 3-million yuan, device installation space is saved, and installation space and maintaining space are guaranteed for full power vehicles and unmanned driving vehicles.

Description

technical field [0001] The invention belongs to rail transit emergency braking technology, in particular to an emergency braking synchronization control circuit and control method for rail vehicles during rescue. Background technique [0002] The Hong Kong South Island Line is the first fully unmanned high-end subway project built by Changke Co., Ltd. for Hong Kong. The train is composed of 3 cars. According to the contract and vehicle safety requirements, the braking system must be based on each bogie. The brake control form (hereinafter referred to as frame control), that is, each bogie is equipped with a brake control unit, a total of 6 sets in the whole train, so as to ensure that the impact on vehicle operation is minimized in the event of a brake control unit failure. Due to the vehicle configuration of the full-motion vehicle, coupled with the fact that the signal system is equipped with various antennas and derailment detection devices, etc., the layout of the vehicl...
