| "Made in China 2025" proposes to accelerate the transformation and upgrading of the manufacturing industry,with the development of intelligent manufacturing as the main direction.Manufacturing informatization is the core of the development of intelligent manufacturing.With the continuous deepening of manufacturing informatization,the modern corporate philosophy of refined management and flexible production has become increasingly popular.The extensive application of production scheduling and process management software represented by the Execution Manufacturing System(MES)is the basis and prerequisite for the realization of intelligent manufacturing.China’s MES system market is in a period of rapid growth,with huge potential demand.However,from the perspective of the actual application of enterprises,the current Web-based execution manufacturing system still has some significant problems in terms of versatility,stability,scalability,maintainability,etc.,resulting in application effects that are not as good as expected and insufficient enterprise participation.In this paper,by studying the factory informatization production process,introducing the service-oriented development idea of??micro-service architecture,the MES system is divided into services and componentized development.The research content mainly includes the following aspects:(1)Design an execution manufacturing system architecture based on microservices.Assess the business functions of the system,divide microservices according to business functions,and design five business units for the MES system: system management services,material management services,process management services,planning management services,and data visualization services.Service governance is performed through service splitting and microservice components,and multiple microservices are coordinated to realize the distributed integration of system business.(2)Combined with architecture design,Spring Cloud Alibaba microservice framework is used to design basic component services in detail,including Nacos service registration and configuration center,Spring Cloud Gateway implements routing gateway services,and integrates Ribbon in the gateway service to achieve load balancing,and integrates Open Feign to achieve remote Service call,integrate Sentinel to achieve service fault tolerance and current limit.For the detailed design of business services,the Springboot framework and MVC pattern are used to design the business architecture level,and the interface of the business service is designed in combination with the sequence diagram model.The front-end and back-end separation development model is adopted,and the out-of-the-box Lay UI is used to realize the front-end interface of the system and complete the integration of front and back-end projects.(3)Deployment and testing.A continuous integration automated deployment plan based on Docker containers is proposed,which is conducive to rapid system iteration and effectively reduces operation and maintenance costs.In order to ensure the reliability of the system’s functions,a corresponding interface test case is designed for each microservice,and the microservice interface is simulated and invoked to verify the system function and performance.Based on the above technology development system,the service componentized development,independent deployment,and agile development have been realized,and good application effects have been achieved in improving the scalability,stability and maintainability of the system. |
