Urban railway traffic full automatic operation signal vehicle-mounted equipment failure emergency processing method

Abstract

The embodiment of the invention provides an urban railway traffic full automatic operation signal vehicle-mounted equipment failure emergency processing method. The method comprises the steps that operation state monitoring is conducted on a control end vehicle-mounted train automatic operation system ATO and a control end vehicle-mounted automatic protection sub system ATP in real time; if the control end vehicle-mounted ATO is subjected to breakdown, and the control end vehicle-mounted ATP runs normally, the control end vehicle-mounted ATP sends out a constant speed train control signal anda forward operating signal, so that the train runs to a next station in a constant speed mode. When the vehicle-mounted ATO is subjected to breakdown, and the control end vehicle-mounted ATP runs normally, the control site vehicle-mounted ATP sends out the constant speed train control signal and the forward operating signal, accordingly the train is controlled to run to the next station, and thendriven manually, accordingly the failure rescue difficulty is lowered, and the influences to the operation order are decreased.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of rail transit, and in particular to a method for emergency handling of failures of on-board equipment for fully automatic operation signals of urban rail transit. Background technique [0002] In recent years, urban rail transit has developed rapidly. At the end of 2016, there were 29 rail transit operating cities across the country, with an operating mileage of 4,069 kilometers. The International Association of Public Transport (UITP) estimates that by 2020, 75% of new lines in the world will use FAO technology, and 40% of existing lines will use FAO technology during renovation. It is estimated that there will be 2,300 kilometers of fully automatic lines in the world in 2025, of which 75% of the newly added FAO lines will be constructed in China. [0003] my country has also introduced foreign automatic operation systems for the Beijing Airport Line and Shanghai Metro Line 10. ...

AI Technical Summary

Problems solved by technology

Once the signal on-board equipment or vehicle interface equipment fails, the train will apply emergency brakes to stop, and the driver needs to get on the train to drive the train manually. If the train stops between two stations, it will increase the difficulty of fault rescue and seriously affect the operation order
