Research On Virtualization Technology Of Intensive Warehousing Operation Monitoring And Control

The storage monitoring system is used to monitor the storage devices,shelves and other resources and operation processes,and is the guarantee of stable and efficient operation of the storage operation.With the continuous development of e-commerce and logistics industry,the scale of storage continues to expand and the storage structure is continuously upgraded.In order to improve the utilization of storage space,intensive storage is gradually put into use,and more and more device is involved in the operation process.Due to the characteristics of huge order volume and multiple heterogeneous devices,it leads to complex operation logic and difficult to achieve unified distributed monitoring of storage devices.Traditional single-architecture storage system software can no longer handle remote tracking and control of storage devices and operation processes.In order to improve the efficiency and guarantee the quality of warehouse operations,this article mainly focuses on the monitoring of intensive warehouse operations,using OPC(Object Linking and Embedding for Process Control)devices unified communication technology,modern network service technology,and database technology to explore warehouse resources and work flow virtualization methods and technical approaches.The main research contents are as follows:(1)Virtualization method and system design of intensive warehouse monitoring and controlIn order to solve the problems of multiple heterogeneous devices and complex operation logic in intensive warehouse,a virtualization method and technical approach for storage resource and operation process monitoring are proposed.This approach connects physical entities,process entities,digital entities,data storage and services through communication,build a virtual-real mapping and bidirectional feedback mechanism between the storage entity and the digital entity.Among them,build a storage resource relation database and object relationship mapping model to provide a unified data storage and access basis for the system;use industrial OPC communication technology,object-oriented and service-oriented methods to establish physical device functions to virtual device objects and service function mapping model to realize the virtual control and interconnection of storage devices;based on the analysis of the operation process and its constituent activities,an event rule-driven storage operation tracking and control model is established.Aiming at the problems of traditional singlearchitecture warehouse software system with heavy functional coupling,poor concurrent response capability,and difficult load balancing,a microservice architecture for a dense warehouse monitoring system was designed.(2)OPC based storage heterogeneous devices monitoring virtualizationThe warehouse uses PLC to control the execution devices.Due to the different types of devices and different PLC models,it is difficult to interact with the application and field data.OPC communication technology is used to build a unified and simple devices data access mechanism.The running status is converted into a readable and writable variable in the OPC server.A method for remote access and monitoring of distributed warehouse devices are proposed.Using real-time Web and Web API service technology,the virtual device object is further encapsulated into a device microservice.The monitoring terminal accesses the virtualized service to achieve remote access to field devices and control,present and track the operating status,mechanical failure,communication failure,power information,etc.of the storage devices on the browser.(3)Virtualization based on event-driven workflow monitoringIntensive warehousing operations have many links and are event-driven.Based on the workflow process virtualization model,define event rules such as process activity triggering,warehousing process initiation,and RGV congestion processing.Obtain device status based on OPC services,perform rule matching and response,execute job decisions,control device actions,dispatch storage resources,etc.,and build eventdriven workflow control mechanisms.Based on field operation scenarios monitoring views,real-time SignalR technology is used to track the progress of parallel multitasking operations,inventory changes,and online device failures in real time.According to the CAP principle,the message middleware RabbitMQ technology is used to broadcast microservice messages,which overcomes the problem of data loss caused by communication delays and interruptions and ensures the consistency of distributed job transactions.(4)Development and implementation of intensive warehouse monitoring systemThe project was funded by the Scientific Research Project of Shanghai Science and Technology Commission(17DZ2283800)and the 2018 Songjiang District Collaborative Service-oriented High-efficient Intelligent Storage System Development and Demonstration Application Project(2018-01).According to the monitoring requirements of the warehouse operation process,the software development technology and system topology are given.Docker container technology is used to quickly deploy microservices to different servers,which overcomes the problem of difficulty in deployment due to the large number of services.In order to solve the problem of scattered microservices that are not easy to manage and the health status difficult to monitor,the registration discovery and heartbeat check mechanism of Consul is used to monitor the service survival status in real time on the monitoring end.Aiming at the problems of bloated volume and limited operating platform of traditional warehouse monitoring software,ASP.NET Core MVC technology is used to carry out detailed design and implementation of warehouse devices and operation process modules.Developed a web-based real-time monitoring system for warehouse operations,which was tested by enterprises to verify its effectiveness.In summary,research has been carried out in the areas of intensive warehouse resource modeling,heterogeneous device virtualization,job flow virtualization,design and integration of warehouse operation services in a distributed environment,and implementation and deployment of a warehouse monitoring system based on a microservice architecture.This paper proposes a method and technical approach for the virtualization of warehousing operations monitoring and control,develops a set of realtime monitoring system for warehousing operations based on Web,and has been effectively applied.
