Metro Equipment Operation And Maintenance Analysis System:Design And Implementation

With the continuous development of the city,the subway is also in the rapid construction,the number of subway operation mileage and equipment in cities across the country is also increasing.As the main artery of metro network information transmission,it covers business telephone,transmission,wireless cluster and other subsystems.The pressure of equipment operation and maintenance in the system is also increasing.Based on the actual project requirements,this paper discusses the limitations of relying solely on the failure experience of the operation and maintenance specialist in the current subway equipment operation and maintenance work.Combined with the existing centralized management platform data of the subway system,this paper analyzes the equipment health,equipment failure alarm,equipment failure alarm,equipment failure alarm,equipment failure alarm,etc Design and implement the metro equipment operation and maintenance analysis system from the aspects of fault expert experience.The practical significance of this topic is mainly reflected in: using Internet technology to maintain the equipment will reduce the operation and maintenance costs,effectively reduce the failure rate of the equipment,reduce the downtime of the equipment and improve the service life of the equipment;The expert fault experience database is established,and the fault causes are identified under the guidance of expert experience,so as to provide work quality and efficiency.The main research work of this topic includes the overall design of the metro equipment operation and maintenance analysis system,and then according to the specific business of operation and maintenance analysis,starting from the overall framework of the system,the detailed analysis and design of the equipment health analysis,expert fault experience and other modules in the system.The analytic hierarchy process(AHP)is used to divide the weight of the running parameters of the equipment,and then the composition of the health evaluation function is introduced by taking the server as an example.In the part of fault expert experience,the construction process of fault fingerprint database is mainly introduced.Simhash is used to extract fingerprint value from fault experience.Finally,starting from the system login,all the functions of the system designed and implemented in this subject are tested,and the gradual operation is briefly introduced and summarized.Metro equipment operation and maintenance analysis system adopts browser /server structure,which is developed based on Java platform.The interface is designed and displayed using Vue framework.The system has friendly interface,easy operation,strong expansibility and maintainability,and meets the needs of daily operation and maintenance of metro equipment.
