Research On Integrated Management Information System For Expressway Maintenance

As a bridge for modernization,the expressway is the only way for economic development.The application of informatization of highway maintenance management is a management concept that adapts to the trend of the times.It is of great significance for exerting the best benefits of highway resources and ensuring the intelligent,scientific and modernization of highway management decisions.Based on the analysis of the problems of low level of refinement of existing maintenance,management informationization and low level of intelligence,this paper puts forward the concept of constructing comprehensive management information system for conservation.Furthermore,through the research on the evaluation and prediction of the performance of highway pavement and bridge,the analysis of the information configuration of highway maintenance resources,and the design and implementation of the comprehensive management information system for maintenance,it provides theoretical guidance for improving the maintenance management level of expressway.And technical approach.The first part of the comprehensive management information system for highway maintenance is to promote the scientific decision-making of conservation decision-making.Through the analysis of performance evaluation and condition prediction of highway pavement and bridge,it is necessary to rationally determine the demand and allocation plan of maintenance funds and optimize the decision of highway maintenance.Provide scientific basis.The second is to solve the problem of fragmentation of highway maintenance basic information,highlight the gathering,sharing and opening of basic information of the industry,form the industry’s big data capacity,and then change the traditional highway maintenance management mode to ensure the operational efficiency of the road,adapt to modernization,large Scale and high quality highway maintenance requirements.The third is to solve the problem of insufficient power of highway maintenance management,focus on innovative development concepts,optimize the allocation of factors,promote the integration of "Internet+" and maintenance management,and stimulate the endogenous power of highway maintenance development.In the research and evaluation of highway maintenance performance,the performance evaluation and function prediction of expressway pavement and bridge are less involved in the actual application of the maintenance system of the current grassroots units.The grey theoretical model,analytic hierarchy process and fuzzy comprehensive evaluation are adopted.The method and other methods establish a specific evaluation model to study the performanceevaluation and prediction of highway pavement performance and the technical indicators of the existing technical status evaluation of the bridge,and make a theoretical attempt for the system to realize this evaluation function.In the research of highway maintenance information resource allocation,this paper summarizes the current maintenance management mode of highways in China,and summarizes the characteristics and shortcomings of current highway informationization development.Through the information fusion theory,the different information involved in high-speed maintenance is graded,and the hierarchical information is combined with the maintenance management mode to realize the fusion of maintenance data information.On the basis of the above research,this paper analyzes the operation process of the highway maintenance integrated management information system,deeply studies the maintenance subsystems and functional module components,selects the system architecture through interaction design theory,and tries to construct a relatively complete maintenance information system framework..Realize the construction and application of the functions of each module of the system,and briefly introduce the basic functions of the system in the maintenance management.By exploring the highway maintenance integrated management information system,the integrated innovation and application of modern information technology will be accelerated,and the intelligent level of highway maintenance management will be effectively improved.Turning the resources of highway maintenance resources from decentralized to intensive,from isolated and closed to sharing and development,and then into a new stage of comprehensive networking,business collaboration,and intelligent application.Change the traditional highway maintenance management mode to ensure the efficiency of highway operation and adapt to modern,refined and high-quality highway maintenance requirements.
