The invention discloses a device for realizing the connection between a train locating system PRW and a vehicle-mounted radio control unit MRCU of a maglev train by using hardware FPGA ((Field Programmable Gate Array). The timeliness of data transmission cannot be ensured by a current interface which is realized between the train locating system PRW and the vehicle-mounted radio control unit MRCU by using software; a data updating period between the train locating system PRW and the vehicle-mounted radio control unit MRCU is 20ms, and a fixed period cannot be ensured by the interface realized by the software. The device disclosed by the invention has the main functions that the interface between the train locating system PRW and the vehicle-mounted radio control unit MRCU is realized by using an FPGA development board, thus the timeliness of the data transmission can be ensured, so that data can be updated in time, and the fixity of the data updating period can also be realized.
