A Routine Inspection System for Passenger Train Tail Device Out of Depot

Abstract

The invention discloses a warehouse-out routine detecting system for passenger train tail devices. The system comprises a train tail controller and a train tail transmission device, wherein the train tail controller is used for sending a 600 kPa air pressure query instruction, a 500 kPa air pressure query instruction and an exhaust and emergency braking instruction to the train tail devices at the heads and / or tails of corresponding trains in sequence according to the value of pressure charged into train pipes of one or more trains to be detected by an air pressure testing system; the train tail transmission device is used for forwarding the 600 kPa air pressure query instruction, the 500 kPa air pressure query instruction and the exhaust and emergency braking instruction to the train tail devices at the heads and / or tails of the corresponding trains in sequence and forwarding received feedback results to the train tail controller; the train tail controller is further used for storing feedback query results, and according to the feedback results and according to whether feedback underpressure auto-prompting is received between 600 kPa air pressure query and 500 kPa air pressure query, whether detection by the train tail controller is qualified is judged. The system improves working efficiency, saves manpower resources and is high in accuracy.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a routine detection system for a passenger train tail device out of the warehouse. Background technique [0002] At the end of September 2013, the whole road completed the transformation of the rear end device of passenger cars, and began to try out the rear end device of passenger cars. The rear end device of the passenger car can operate the rear end device of the passenger car to exhaust the tail and assist the braking of the train, so as to prevent the accident of "release" (brake failure) of the train. [0003] The passenger train tail device is installed at the rear of the passenger train, including vehicle accessories (including antenna feeder system, gas circuit, and DC power supply line) and the main engine of the passenger train tail device (referred to as the passenger train tail main engine). Communicate with LBJ (the train protection and alarm equipment install...

Problems solved by technology

[0031] However, in this scheme, 1) at least 3 operators are required to complete the work; 2) manual control is required to control the air filling of the train pipe to 600kPa and 500kPa, and the accuracy is poor; The accuracy of whether the wind pressure detection error is qualified cannot be guaranteed; 4) It needs to be inflated twice to complete the head and tail exhaust tests respectively, and the efficiency is low: 5) The test records are manually recorded and easy to tamper with; 6) Each group of trains The operation time is about 20 minutes; 7) When different trains operate at the same time, multiple warehouse inspection instruments are required

[0032] To sum up, the methods in the prior art require a large amount of manpower, are not automated, and have low test efficiency and poor accuracy.
