Research And Reality Of Maintenance Production Management System For Harmony Type Locomotive

As an important and independent department of the rail sector, depot undertakes responsibility for railway locomotive preparation, maintenance scheduling and other services, among which locomotive maintenance work ranges one of the three major businesses. In recent years, the rapid development of the computer network technology, speeding up the process of railway informatization, and harmony-type locomotives are put in service, maintenance sector there are two serious problems. A is information level low, maintenance sector original of maintenance mode in the, daily maintenance work in the large of maintenance data needs maintenance personnel to collection summary, locomotive maintenance process in the cannot by repair range standard job, exists undetected, and leak repair of errors risk; also a is maintenance concept needed update, as harmonious type locomotive of constantly introduced and gradually input using, harmonious type locomotive of maintenance mode, and method, and past locomotive different. Summing up the above two points, constructing the harmonious characteristics of locomotive repair information system to improve the maintenance of locomotive depot of information level in the business sector is imperative.This paper discusses c/s mode is based on three layer (Client/Server, client/server mode), using SQL database application development of harmonious production management system for locomotive maintenance. As a whole system. NET as a platform, through in-depth and detailed needs analysis of maintenance departments, at the same time combining the character of harmony-type locomotive repair, has developed the systems to achieve goals and techniques.This paper starts with the analysis of the actual needs of maintenance departments, and maintenance system was divided into the "JT-28system" and "production management system of locomotive depot repair" two subsystems, and each subsystem is a modular Division. And then describes the system architecture and design, including the systems network architecture (client/server mode), system development environment (including the development of platforms and development languages, development tools, and select database system), as well as system design and security design of information sharing (including physical security, logical security and management).Second, the detailed description of production management system for locomotive repair database created, including needs analysis, conceptual design, logical design, database design and database structure modeling, physical security design. Development of database systems is one of the core elements of system development.Finally, based on the above study, eventually developed a harmony-oriented production management system for locomotive repair, describes the various modular system functions have been met before. Systems have been put into use, inspection and production site will work, meet the basic demands of field operations, increase productivity.
