The Research On Locomotive Application Information System

In order to trace and monitor the current speed, position, organization, control status and punctuality or late of the train, as well as to achieve the long distance diagnose, alarm and real time supervise of locomotive equipments, the railway machinery and electrical business departments needs a system urgently to solve all of these requirements as that to improve safety guarantee and management capability of train running, fine, transparence and efficiency of scheduling and command. Therefore, the research on collection, transmit and data process of train running status information is more signally.The research of train running status information system can solve the problems which the business departments faced. Train running status information system is based on "passenger locomotive gear inspect and scheduling query system" of security standard line construction engineering of speed increase of the six main lines constructed began in 2004, the process objects are train running status information from train running safety monitoring, running status on-line detect and intelligent fault diagnose devices and so on, the wireless transmission platform is national public mobile communication or railway specialized communication network, to provide the real time query information of train running condition on the way to railway scheduling and command, running safety monitoring and specialty management department, supply important information of train running status to the appointed running department and real time alarm, establishes emergency communication between ground person and driver on-duty in line with the appointed mode, it is an information process system to transfer and storage the recording information of entered locomotive, train running monitoring device of EMUs and other onboard equipments.Train running status information system consists of onboard and ground parts. The onboard part is to implement the collection and sending of onboard information, while, the ground part is to implement the control on onboard equipments and data receive, process and distribution.
