The Research And Realization Of The Railroad Vehicles Management System And Data Network

At present, except that many enterprises bought a quantity of self-vehicles, there appeared many private railroad vehicles rental companies, the tendency of railroad vehicles operation market-orient is approaching increasingly. HMIS system which can be used by current railroad system is a set of comprehensive railroad vehicles data management system. In order to go after all-round unity, this system has ignored many concrete special problems existed in the process of operation, and a few necessary functions were not perfect, what's more, there hasn't practical application in the aspects in the management of self-vehicles. For many years, a majority of railroad branches carry out the data by the way keeping accounts by hands, whose economic losses is very big. Besides, railroad vehicles management is a particular industry, which demands high in the accuracy of cost assess, and driving safety is also extremely important. However, according to the state regulations, the enterprise self-provided vehicles should be united administration and maintained by the railroad vehicles administrative department, whose publicity is poor, and the enterprise loss is enormous. Therefore, the accurate grasp of the cost of being maintained in operation, the dumping time and the control of operation mechanism are the important problems which must be solved urgently by the administrative department. This topic is exactly advanced owing to this intense market demand.The guiding principle is to ensure that the vehicle operation and the publicity of maintenance and the precise of the enterprise data management. With the introduction of the records of vehicle information which is stored in the HMIS system currently being used, the enterprise completed the projects and contents which were lack in the original system, established a sound vehicle records, and achieved many new functions such as self-definition print, seized vehicles inspect-up warning, accurate data about the seizure, maintenance and the statistical analysis of the cost. The whole information in the operation of vehicles and the costs in the process of operation realized a key statistics. The enterprise established a database based on the local network database, transmitted the local database to network server, Web application server procedure was established in the network sever tip for the use of enterprise inquiries, realized the on-time data updating in the operation. A variety of statistical data analysis applications were also established in the server tip and the publicity between the railway and the enterprises was realized. It established exchange data modules between the local desktop systems and web application systems. A multi-user management functions were achieved and it gave the different authority set-up to the registered users separately. It established a uniformly standard and perfectly standardized data dictionary bank.The ingenious application of this type of development issues made the packaging code reusable largely and repetitively, some even without a programming code to enhance the speed of the development process. It improved the scheme of code input. It made great efforts in the simplicity of the users, so it made the users operate easier. Novel detection updated technology of background information realized the memory function of unfamiliar words. It even tried a brand new way innovative data transmission mode and made great contribution in the seamless aspects between the local data and the network data.
