Data exchange method and platform for railway earthquake early warning

The embodiment of the invention provides a data exchange method and platform for railway earthquake early warning. The method comprises the steps that a data exchange platform receives earthquake information sent by an earthquake station network in real time through a preset transmission special line; the data exchange platform obtains at least one railway bureau corresponding to an area affectedby the earthquake information according to the received earthquake information and sends the earthquake information to a high-speed railway earthquake early warning monitoring railway bureau central system of the railway bureau through a preset railway data communication network; and the quick report information is sent to a railway earthquake emergency processing system through the railway data communication network if the received earthquake information is quick report information of which the earthquake magnitude exceeds a preset earthquake magnitude threshold value. According to the embodiment of the invention, th
