Abstract: A management of vehicle information in new train monitoring device is designed and implemented in the paper. Using double redundant Controller Area Network(CAN) communication network, the management realizes the function, which can on-line synchronous update and manage the train log data, with the online programmable NOR FLASH and mobile massive storage device. Various tests prove that the new vehicle information management employed greatly improves the reliability of train monitoring device, update efficiency and security of the train information.
