Train safety protective method for automatically adjusting braking force service factors of motor train unit

Abstract

The invention relates to a train safety protective method for automatically adjusting braking force service factors of motor train unit, which includes: firstly, arranging a train braking force state monitor on each vehicle of the motor train unit to monitor braking force state of each vehicle in real time; and secondly, using a vehicular subsystem of a train overspeed protective system to receive braking force state information monitored by each vehicle braking force state monitor in real time through an extended information receiving interface or information receiving interface arranged independently, automatically adjusting braking force service factors and train maximum permitted operating speed value according to the information, using a specific arithmetic formula to calculate a train braking distance, and adjusting generated train speed-distance safety protective curves such as a common braking control curve, an emergency braking control curve, a permitted operating speed control curve and the like in real time to automatically realize safety protection in running of the trains so as to improve running safety of the motor train unit.

Description

Technical field [0001] The invention belongs to the field of railway and rail transit, and is a safety protection method involving train operation of EMUs. Specifically, when the braking system of some vehicles of the EMU fails and the braking force is removed, the train overspeed protection system automatically adjusts the braking force Use the coefficient and the value of the maximum allowable train speed to automatically protect the train to avoid the occurrence of false signals, overspeed and cause train collision or overturning accidents. Moreover, when the present invention is used in railway or rail transportation where only mobile trains are operated, even if there are more than 6‰ downhill slopes within the braking distance of the train in the direction of the station outside the station, there is no need to take special measures such as setting up safety lines and continuing the route. Protective measures. Background technique [0002] my country's railway EMU trains a...

Problems solved by technology

[0024] The existing ATP system has the following problems: the EMU braking force utilization coefficient β in the protection curve generated by the ATP on-board subsystem is pre-solidified, so the protection curve generated by the ATP on-board subsystem cannot truly reflect the EMU train braking force good or bad

Therefore, the existing ATP system has a fatal flaw in ensuring the safe operation of trains
