| Trains run monitoring device (LKJ) preventing train aggressive signal, to prevent speeding train and assist drivers to improve their ability to maneuver and other functions, its log data generated by running trains running status data recorded in real time, including the system self-test information software version, maintenance personnel or locomotive crew to enter information such as the amount of information is very rich.In this paper, the principle of log data generated by LKJ-depth study and discussion, the present situation Beijing Railway Bureau, in the "select both mature and reliable mainstream product, but also the fastest speed and minimum cost of organizing implementation" full use of the existing locomotive train running status information system for wireless transmission function (LAIS) devices for system transformation and upgrading, increase and integrate information collection and transmission of the content of the locomotive, and the development of supporting audio calls and video capture devices, completed the transformation of the system-board equipment hardware and software upgrades. Online monitoring of train operation and ultimately the formation of early warning system, safety control locomotive sooner.Online monitoring of train operation developed early warning system, using GSM/ GPRS technology, CDMA2000 1xEV-DO 3G technology to achieve a record of information locomotives and locomotive running information such as log file monitoring safety equipment onboard a locomotive produced, the remote transmission of audio data and video data to solve the data and video transmission over a wireless network selection problem, LKJ draw intelligent search function analysis software, some of the items selected LKJ analysis points as an early warning and alarm the entry point of the system, the non-normal traffic train running impending emergencies are occurring and illegal operations locomotive crew information online real-time early warning and alarm. Ground information center emergency duty officers alert and warning information in real time back, the first time to obtain emergency information, make decisions for the first time provide a credible basis for the disposal, for secondary prevention of accidents happen to gain time, while taking advantage of the system audio, video, field operations to achieve the locomotive crew process real-time monitoring and on-line technical guidance for the first time to stop illegal provide the means to ensure that the locomotive crew be able to seriously implement the traffic rules and regulations, the correct operation of LKJ, regulate locomotive operation.Trains run from early warning system to monitor the online promotion for emergencies means essentially real-time emergency response, as well as after the incident to provide data to support analysis of work processes to achieve control card control sooner, the formation of a security risk early warning efficient management of security risks ahead of the closed-loop prevention and control, improve the use of locomotive safety management. |
