Abstract

The invention discloses a high speed railway earthquake early-warning monitoring information wireless transmission system. The wireless transmission system comprises an earthquake early-warning monitoring communication interface system and a vehicle-mounted earthquake early-warning receiving device, wherein the earthquake early-warning monitoring communication interface system is used for receiving earthquake early-warning information, calculating an earthquake influence range, transmitting the earthquake early-warning information to the vehicle-mounted earthquake early-warning receiving device on a train which is within the earthquake influence range or is to enter the earthquake influence range, and sending a cell broadcast short message including the earthquake early-warning information to a cell within the earthquake influence range in a cell broadcasting way; and the vehicle-mounted earthquake early-warning receiving device is used for transmitting a train position report of the train to the earthquake early-warning monitoring communication interface system, receiving the earthquake early-warning information and the cell broadcast short message including the earthquake early-warning information which are transmitted by the earthquake early-warning monitoring communication interface system, and forwarding the earthquake early-warning information or the cell broadcast short message including the earthquake early-warning information to an emergency processing device to perform a corresponding processing operation after reception of the earthquake early-warning information or the cell broadcast short message including the earthquake early-warning information. Through adoption of the wireless transmission system, earthquake early-warning monitoring can be finished rapidly, and the train running safety is ensured.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a wireless transmission system for high-speed railway earthquake early warning and monitoring information. Background technique [0002] Earthquake is a natural disaster with great harm. When it is serious, it will directly damage the railway infrastructure and cause train operation safety accidents. Building an effective railway earthquake early warning and monitoring system can reduce the loss of trains when disasters occur. [0003] Earthquake early warning technology uses the speed difference between P wave and S wave, and the speed difference between electrical signal and seismic wave. After an earthquake occurs, an early warning is issued seconds to tens of seconds before the destructive seismic wave strikes, so that corresponding measures can be taken. For high-speed trains, it is very important to quickly and accurately send early warning data to the on-board vehicl...
