Abstract

The invention relates to an earthquake emergency processing method and system for a high speed railway. The method comprises the steps that a railway administration central system receives earthquake alarming information, determines the earthquake alarming information and then releases the earthquake alarming information; an earthquake monitoring pre-alarming station receives the released earthquake alarming information and then controls a traction substation overhead line system in a corresponding area to cut off power; a vehicle-mounted emergency processing device receives the released earthquake alarming information and then controls a train to brake emergently at necessary time according to the earthquake alarming information and the detected overhead line system power off state; a train operation control system receives the released earthquake alarming information, and then controls the operation mode of the train and conducts modulation control to forbid other trains to enter earthquake areas according to the alarming grade of the earthquake alarming information. Through the earthquake emergency processing method and system, the reliability and the timeliness of earthquake emergency treatment are effectively improved.

Description

technical field

[0001] The invention relates to the technical field of train operation control, in particular to a high-speed railway earthquake emergency treatment method and system. Background technique

[0002] The development of foreign high-speed railway earthquake emergency response systems is different. Although Japan and my country’s Taiwan high-speed railway emergency earthquake emergency response systems have realized the early warning function by using the speed difference between P wave and S wave, and the speed difference between electromagnetic wave and seismic wave. In terms of the alarm method, the seismographs along the line can directly control the traction power supply system after identifying the authenticity of the earthquake, without the need for confirmation by the dispatch center. The control signal transmission links are less and the real-time performance is strong. However, due to the lack of an earthquake information confirmation link, it is prone ...
