Operation information long-distance centralized acquisition device and acquisition method for railway vehicle gate controllers

The invention relates to an operation information long-distance centralized acquisition device for railway vehicle gate controllers. The device comprises monitors and an antenna, wherein the monitors are connected with the gate controllers, the gate controllers are arranged on every door leaf of a railway vehicle, and a local area network is automatically formed by the monitors in a same compartment through a short-distance wireless channel; the monitors at the head and tail ends of every compartment as gateways are connected with the monitors of the adjacent compartments so as to combine the whole vehicle and form an integral network; and the monitor comprises a signal acquisition interface, a core processing unit, a wireless communication module and a device power supply, wherein 3G (The 3rd Generation Telecommunication) modules are arranged in the monitors at the head and tail ends of the vehicle. Compared with the prior art, all data of vehicle doors is shared by the device, and the vehicle actively transmits data to a monitor center, so that the phenomenon that the user acquits the data from the doors one by one can be gone forever; and the data is complete, and the analysis on the states of the vehicle is more accurate.
