Control method for subway escape platforms

Abstract

The invention discloses a control method for subway escape platforms. The control method comprises the following steps: defining escape platform information, namely starting and ending coordinates and side directions to which the escape platforms belong; defining an overlapping effective length; according to the effective overlapping length and the escape platform information, periodically scanning the overlapping condition of a train head and each escape platform, and updating an escape platform overlapping list; when a train is static in emergency, selecting all types of escape platforms which are effectively overlapped in the escape platform overlapping list; calculating the overlapping position distance of each effectively overlapped escape platform, and calculating the numbers of all overlapped train doors according to the train door distance and the lateral directions of the escape platforms; and according to the overlapped train door numbers, relieving and opening the closing keeping protection enabling of the train doors, and keeping the other train doors in a closed and locked state. According to the invention, the arrangement flexibility of the escape platforms can be greatly improved, a train door leading to the escape platform can be accurately opened, and rapidness and safety are improved.

Description

technical field [0001] The invention relates to a control method for a subway escape platform. Background technique [0002] In the field of urban rail transit signal control, the fully automatic driverless system (FAO) has become the mainstream system solution in the future. In the subway operation scenario without a train driver, the train encounters an emergency in the platform section, such as fireworks, passengers trigger the emergency brake handle, etc. If the train cannot continue to stop at the platform, it is particularly important to evacuate passengers safely and quickly through the escape platform important. [0003] At present, rail traffic signaling system applies a protection to keep closed after the train door is closed and locked. When the train encounters an emergency and stops in the section, it is judged whether the train overlaps with the escape platform defined in the database by at least one door, and then the door on the side of the escape platform ...

AI Technical Summary

Problems solved by technology

But this scheme has proposed requirement for the construction of escape platform, once the length of escape platform is less than 1 / 2nd of vehicle body length, after train stops, escape platform is just between the two coordinates of center point and front (or car tail), The system cannot make an accurate judgment of effective overlap, thus losing the chance of emergency evacuation

Or when there are multiple escape platforms overlapping on one side or both sides after the train stops, the system cannot accurately determine all available escape platforms, and does not make full use of all available escape platforms to quickly evacuate passengers

[0005] In addition, when the system judges that the current escape platform effectively overlaps with the escape platform, it will completely cancel the closing protection enablement of all doors on this side according to whether the escape platform defined in the database is on the left or right side of the train. Escape platforms have no overlapping doors into the track, introducing new risks
