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

Embodiment Construction
[0067] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0068] 1. The train safety protection method for automatically adjusting the braking force utilization coefficient of multiple train units, comprising the following steps:
[0069] (1), such as figure 1 As shown, a vehicle braking force state monitor D is installed on each vehicle of the EMU train 1 ~D N , monitor the braking force status of each vehicle in real time, and transmit the monitored braking force status information to the ATP on-board subsystem B in real time;
[0070] (2), such as figure 1 As shown, the information receiving interface A is set on the ATP vehicle-mounted subsystem B, and the information receiving interface A passes through the information transmission channel C 1 ~C N Corresponding to receiving vehicle braking force status monitor D 1 ~D N For the monitored braking force status information, A can adopt the met...

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 railways and rail transit, and relates to a safety protection method for the operation of trains of multiple trains. Specifically, when the braking system of some vehicles of the multiple trains fails and the braking force is cut off, the train overspeed protection system automatically adjusts the braking force Using the value of the coefficient and the maximum allowable speed of the train, the safety protection method is automatically carried out on the train to avoid the safety protection method of the train collision or overturning accident caused by the rash signal and overspeed. And when the present invention is used on the railway or rail transit of only driving trains, even if there are more than 6‰ downhill slopes in the braking distance range of trains outside the station, there is no need to take special measures such as safety lines and continuation routes. protective measures. Background technique [0...
