Rail train brake control, train state detection and train integrity detection method

Abstract

The invention relates to a rail train brake control, train state detection and train integrity detection method, and provides a train tail brake system, a positioning device, train motion state detection equipment and external communication equipment which are integrated on the basis of an equipment bearing platform externally hung on a train tail vehicle and is provided with a power supply device. Coordinated and optimized brake among the train tail brake system, the control locomotive brake system and the multi-heading locomotive brake system (if a multi-heading locomotive exists) is achieved, or the train tail brake system serves as redundancy of the control locomotive brake system to improve the brake availability, or the train tail brake system serves as rescue equipment for brake a fault train independently. And through train state detection, accurate and rapid closed-loop brake control is realized. By acquiring information such as train tail positioning, motion state and tail pipe pressure, locomotive control equipment can be operated to detect train integrity in real time. The locomotive control equipment can be used for train operation control according to the state information. A locomotive control device or a ground server can be operated to record key parameters and states of train operation and can also be used for functions of fault early warning and the like.

Description

technical field [0001] The invention belongs to the field of rail transportation, and in particular relates to a method for rail train braking control, train state detection, and train integrity detection. Background technique [0002] With the development and progress of society, the logistics transportation is getting more and more busy, which requires rail trains to run faster and faster, and the running intervals are getting shorter and shorter. more and more. In order to ensure the safety of rail traffic, there is an urgent need for a braking system that can adapt to modern rail traffic, supplementary collection of important states of train operation, and methods and equipment for real-time detection of train integrity. [0003] The following problems exist in the current status of the existing track train braking control and detection and train integrity detection: [0004] 1) The length of the train is increased due to the large number of vehicles mounted on it, esp...

AI Technical Summary

Problems solved by technology

[0004] 1) The length of the train is increased due to the large number of vehicles mounted on it, especially the heavy-duty train, which generally exceeds 100 vehicles. The transmission speed of the air braking force through the air wave is slow, and the delay time from the braking command output by the control locomotive to the braking execution of the entire train Long, especially when the traction turns to braking, the longitudinal impact of the train is large, which is likely to cause safety accidents such as broken hooks and decouplings, affecting driving safety and efficiency

2) Due to the increase in length due to the large number of vehicles mounted on the train, especially for heavy-duty trains, which generally exceed 100 vehicles, the air filling time of the entire train tube increases, and the time interval between train brake relief increases. The impact is large, and it is easy to cause safety accidents such as broken hooks and decouplings, which will affect driving safety and efficiency.

[0005] 3) The air pressure value of the train tube is an important monitoring value for the train operation safety system, especially for heavy-duty trains, but the vehicle does not provide power supply or it is difficult to provide power supply equipment, and it is difficult to provide a fixed space for equipment installation, so that the tail of the train tube Air pressure detection is difficult to implement

[0006] 4) After the locomotive braking system fails, no backup braking system is put into operation, causing the train to fail to run normally or run at low speed, seriously affecting the efficiency of railway operations

[0007] 5) It is difficult to judge the integrity of the train during train operation, which seriously affects the safety of train operation

The application number is "201510356905.7", the application date is "2015.06.25", the publication number is "CN104925090A", the publication date is "2015.09.23", the name is "A method for detecting the integrity of trains", and the applicant is " The Chinese invention patent of Zhuzhou CSR Times Electric Co., Ltd., the invention discloses a train integrity detection method, which belongs to the technical field of trains, to solve the problem that the accuracy of the train integrity detection method in the prior art is not high and easy A technical problem affected by the state of the train interface. The detection method for the integrity of the train includes: the first on-board device obtains information from the last reference transponder group; the first on-board device combines the obtained first running speed with the obtained information Calculate the first position with the preset train route, wherein the first running speed is the train running speed acquired by the first vehicle-mounted device, and the first position is the current position of the first vehicle-mounted device; The second position of the device, wherein the second position is the current position of the second vehicle-mounted device; the first vehicle-mounted device combines the preset train route and train length, and judges whether the train is complete according to the first position and the second position
