System and method for preventing vehicles from derailing at endpoints of rail transit line

Abstract

The invention relates to the technical field of rail transit, in particular to a system and method for preventing vehicles from derailing at the endpoints of a rail transit line. The system and method aim to solve the technical problem that an existing method is poor in derailing preventing effect. The system comprises vehicle-mounted warning units installed in cabs of vehicles, and a plurality of stress wave sensing devices installed at the line endpoints on a rail respectively. A stress wave sensor, a signal processing module and a wireless signal transmitting module are arranged in each stress wave sensing device. Each vehicle-mounted warning unit comprises a vehicle-mounted warning terminal and a vehicle-mounted wireless signal receiving module. All the stress wave sensing devices monitor rail stress signals through the stress wave sensors, evaluate the risk grade of derailing of the vehicles according to the monitored signals, and then transmit corresponding wireless warning signals to the vehicle-mounted wireless signal receiving modules in the cabs of the vehicles through the wireless signal transmitting modules. According to the system and method, derailing of the vehicles can be prevented, and the implementation cost is low.

Description

technical field [0001] The invention relates to rail transit technology, in particular to a rail transit line endpoint vehicle derailment prevention system and a derailment prevention method thereof. Background technique [0002] There are a large number of line endpoints on the rail transit line. When the vehicle approaches the endpoint, the vehicle’s rushing signal or driver’s human error will easily lead to the derailment of the vehicle, especially in the endpoint area of ​​the test run line and the turnback line of the urban rail transit line. In order to prevent the vehicle from rushing out of the end point of the line, the existing measures mainly use the anti-collision soil block, but because this type of device can only effectively play a role when the vehicle speed is very small, when the vehicle approaches the end point from a long distance at a faster speed, the anti-collision The earth bumper cannot give timely instructions to the driver or the vehicle, and it is...
