Fully automatic unmanned subway or urban railway track detection method

Abstract

The invention relates to a full-automatic unmanned subway or urban subway track detection method. The method comprises the steps that a full-automatic control system communicates with full-automatic unmanned track measuring car receiving and dispatching systems of all stations through a communication network, and controls the full-automatic unmanned track measuring car receiving and dispatching systems to work; the full-automatic unmanned track measuring car receiving and dispatching systems release qualified track measuring cars and rescue cars after detection to an operating orbit according to instructions of the full-automatic control system; the track measuring cars and the rescue cars which are released on the operating orbit detects double tracks to a certain speed at the same time, and if a suspicious sign is detected, suspicious sign data is uploaded; returning is conducted after detection is completed, and the full-automatic unmanned track measuring car receiving and dispatching systems put away the track measuring cars and the rescue cars, and then conducts defection, charging and supplement of coupling agent on the track measuring cars. According to full-automatic unmanned subway or urban subway track detection method, automatic and unmanned track detection is basically achieved, the detection efficiency is high, the speed is high, and the reliability of the data is high.

Description

technical field [0001] The invention relates to a fully automatic unmanned subway or urban railway track detection method. Background technique [0002] Track detection is an important part of ensuring the safe operation of rail transit. Due to the characteristics of high operating density of rail locomotives, short time intervals, and high passenger density, the track wear is relatively serious, and various hidden dangers are prone to occur when running for a long time. The detection has also become the top priority of the rail transportation safety link. [0003] The current detection method is that after the operation is over at night, the inspectors push the track inspection vehicle on the track for inspection. The instrument uses an old simulator, and the inspectors conduct on-site interpretation according to the real-time alarm situation. The disadvantages are obvious: 1) Can The inability to detect defects is related to the experience of the inspectors pushing the tr...

[0003] The current detection method is that after the operation is over at night, the inspectors push the track inspection vehicle on the track for inspection. The instrument uses an old simulator, and the inspectors conduct on-site interpretation according to the real-time alarm situation. The disadvantages are obvious: 1) Can The inability to detect defects is related to the experience of the inspectors in pushing the track inspection vehicle, 2) the inability to compare the inspection data, 3) the judgment of defects is related to the experience of the inspectors, 4) the use of a large number of inspectors

[0004] The total mileage of Beijing’s subway in 2015 was 666 kilometers, and it will reach 1,036 kilometers by 2020. The time for inspection is less than 4 hours every night when the subway is out of service. Completing all track lines will require a lot of personnel, equipment and time

[0005] In addition, the currently detected data are all the gate signals collected by the simulator, and the saved picture format does not have the value of multiple comparisons at the same position and horizontal comparison of position signals, so intelligent and automated data management and detection cycle arrangements cannot be achieved. The intelligentization of the track also cannot predict the service life and replacement date of the track. Each ultrasonic probe collects one piece of data every 1mm. There are 9 probes in total, that is, 9 pieces of data need to be collected every 1mm. A suitable data processing system will not achieve the desired results
