Design And Development Of Daily Management And Maintenance System For Expressway Mechanical And Electrical Equipment Based On NFC

With the rapid development of China ’s expressways,the formed expressway network has become increasingly perfect,and the scale of expressway electromechanical systems has also increased rapidly,which has increased the difficulty of management and maintenance of electromechanical equipment to a certain extent.At present,the traditional highway electromechanical maintenance mode has the problems of extensive equipment maintenance and unreasonable equipment maintenance strategy,which is difficult to meet the maintenance needs of electromechanical equipment.In order to optimize the maintenance cost of equipment,the maintenance strategy of electromechanical equipment is studied by comprehensive evaluation method.In order to improve the maintenance level of electromechanical system,the daily maintenance system of electromechanical equipment based on NFC is designed and developed.First of all,according to the general situation of highway electromechanical system,how to realize the whole life cycle management process of highway electromechanical equipment is studied.The fine management of equipment and equipment information by using NFC technology is the basis of the whole life cycle management of electromechanical equipment.In the process of equipment operation and maintenance,relying on the management and maintenance system platform and the standardized management and maintenance system of equipment,the supervision and tracking of the whole life process of electromechanical equipment is completed.The index system of influencing factors of maintenance strategy is established by fuzzy hierarchy comprehensive evaluation method.The weight of each influencing factor index is determined by analytic hierarchy process,and the comprehensive evaluation of equipment maintenance strategy is completed by fuzzy comprehensive evaluation method.Then,according to the current high-speed management mode and maintenance mode,the demand analysis of the system is completed,including user demand analysis,business demand analysis and functional demand analysis,and the construction goal of the system is defined.Secondly,on the basis of demand analysis,the paper completes the design of the overall architecture of the system,including from the underlying NFC-based equipment fine management design to the physical network architecture and software technology architecture design of the system,and then to the specific functional modules and database design.The system function module design is mainly a picture display,facility management,maintenance standard management,maintenance management,event management and mobile terminal functions,and the key business processes of each function module are designed.The database part completes the detailed design after analyzing the dynamic and static data requirements of the system,including the logical structure and physical structure design of the database.Finally,the development and implementation of the system are completed by using Java development platform and Postre SQL database technology.
