Design And Development Of Manufacturing Execution System For Hydraulic Component

The manufacturing industry of hydraulic component is the basic industry of national economy.With the strong support of "Made in China 2025" and other national policies for the intelligent upgrading of manufacturing industry,and the deep integration of digital,automation technology and traditional manufacturing industry,the manufacturing industry of hydraulic component is rapidly transforming to intelligent production.At present,the production management mode of hydraulic component mainly depends on manpower,which has the problems of low production efficiency and unbalanced resource distribution.Therefore,the design and development of MES in this paper is of great significance to improve the production efficiency,balance the resource allocation,and improve the intelligent level of hydraulic component manufacturing enterprises.The general scheme of MES for hydraulic component is designed.According to the flexible characteristics of the hydraulic component manufacturing workshop,the requirements of the manufacturing workshop for the hydraulic component MES are put forward.The overall scheme of MES is designed.The business process of the main sub modules(Including material management,equipment management,tooling management,process management and assembly management)is optimized.The overall data process business and the data process of the main sub modules are analyzed.The production scheduling algorithm is studied.First of all,based on the actual production scheduling of the workshop,the overall production scheduling process of hydraulic component is designed,which is regarded as a multi-objective flexible job shop scheduling problem,and the mathematical model of the job shop scheduling problem is established.Secondly,according to the characteristics of hydraulic component manufacturing process,NSGA-Ⅱ algorithm is selected as the optimization algorithm of hydraulic component manufacturing workshop production scheduling model.The operation principle of the algorithm is analyzed,and the encoding and decoding process,crossover,selection and mutation genetic operators are designed.Finally,according to the actual production data,using NSGA-II algorithm to optimize the workshop production scheduling,the results show that using NSGA-II algorithm to optimize the production scheduling can effectively achieve the maximum processing time is short,the equipment load rate is low,and the production cost is low.The technology of data acquisition and production tracking is studied.First of all,according to the actual situation of the enterprise,using C/S architecture as the MES infrastructure,the MES database management model is designed.Secondly,the data acquisition requirements are analyzed,and the data to be collected are determined as start-up time,current status of equipment,etc.the data acquisition scheme is distributed acquisition and centralized management.The data acquisition technology and transmission mode of FANUC CNC machining center and general machine tools are emphatically analyzed.Finally,according to the production process of manufacturing workshop,the framework of production tracking system is determined,and the main modules of production tracking,such as work order tracking,material tracking,quality detection are analyzed.The operation of MES is studied.The operation environment of MES and the functions of main modules(Including login interface,basic data management module,production plan management module and production process tracking module)are described.Taking ms 18 valve body processing as an example,the actual production management process is run in MES.The results show that the management of the processing process of the hydraulic valve body by MES can improve the production efficiency Shorten the production cycle,save production costs,balance the allocation of resources and so on have a positive role.
