Synchronous control circuit and method for rail-vehicle-rescue emergency braking

Abstract

A rail vehicle rescue emergency braking synchronous control circuit, which is connected in parallel to the normally closed contact of the linked relay and the emergency braking relay on the emergency braking train line circuit of the lead car of the rescue vehicle and the faulty vehicle, and is used for rescue trains Rebuild the emergency braking train line circuit after connecting with the faulty train; at the same time, configure the brake isolating switch on the head car of the rescue vehicle and the faulty car, connect the rescue head and tail relay and brake isolation relay in parallel, and the emergency braking of the driver's station The normally closed contact of the button is connected in series to the circuit of the emergency brake train line, and the brake isolation solenoid valves of all vehicles are connected in parallel to the circuit of the emergency train line, and the power is supplied by the circuit of the emergency train line. The valve realizes the synchronous control of emergency braking under rescue conditions. The control method of the present invention is safe and reliable, and the synchronization is precise, which saves more than 3 million yuan in procurement costs for the entire project, saves equipment installation space, and ensures installation and maintenance space for the configuration of full-motion vehicles + driverless 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...
