Design And Implementation Of Remote Monitoring System Of Type LKJ15 Train Monitoring Device

Since railways restructuring for China Ministry of railway, the construction of railway informatization in all aspects of railway advances rapidly in recent years. LKJ is an important part of train control system and works as train operation data provider at the same time, and it is necessary to join the process of railway informatization. Especially the establishment of railway GSM-R private network and LAIS wireless transmission system creates the conditions of diversified applications of LKJ information.The core technology of LKJ 15 remote monitoring system is monitoring the operation state of the train from the analysis results which conducted by analyzing LKJ operation data. This paper uses the UML unified modeling language (UML) as the requirement analysis and system design tools, and describes the network architecture needed by the system in the requirements analysis phase.Based on the analysis of main business processes such as the equipment quality surveillance, the driver control monitoring and the train schedule monitoring, paper deduces the demands of use case diagram and the entity data of the system. It also creates an extensible analysis warehouse and the analysis model of the equipment quality surveillance, the driver control monitoring and the train schedule monitoring and so on, and it implies the analysis function after the model adding to the warehouse.Finally, this paper summarizes the characteristics of LKJ 15 remote monitoring system, and prospects the system in the equipment life early warning, automatic drawing locomotive turnover figure, interacting with other systems and the applications of big data analysis, etc.
