Description

Technical Field

[0001] The present invention relates to the field of virtualization and intelligent manufacturing, and in particular to an intelligent management system for a household appliance shell spraying production line based on server virtualization. Background Art

[0002] As the digitalization and intelligent transformation of production lines is accelerating, there are compatibility issues between industrial computer hardware and operating systems when transforming the original home appliance shell spraying production line. When upgrading the server, the hardware, operating system, industrial control software and project files must be upgraded at the same time. A large number of SCS and HMI involved in the production site must also be upgraded simultaneously for software and hardware environment, which is expensive, labor-intensive and affects normal production.

[0003] The concept of virtualization was first proposed by IBM. It allocates limited computer physical resources according to actual usage needs to achieve resource optimization. Virtualization technology realizes the logical abstraction and unified representation of IT resources and redefines the division of IT resources, realizes dynamic allocation, flexible scheduling and cross-domain sharing of resources, and can effectively integrate computer hardware resources and improve resource utilization. Virtualization technology mainly includes network virtualization, storage virtualization and server virtualization technology.

[0004] As the core of virtualization technology, server virtualization technology is the most mature and widely used. Server virtualization technology refers to the use of virtualization technology to give full play to the hardware performance of the server. While ensuring the investment cost of the enterprise, it can improve operational efficiency, save energy, reduce economic costs and space waste. For users with rapid development and large growth, server virtualization technology can bring more economic benefits. Summary of the invention

[0005] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide an intelligent management system for household appliance shell spraying production line based on server virtualization.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] An intelligent management system for a home appliance shell spraying production line based on server virtualization is used to achieve compatibility of multiple industrial control systems of the home appliance shell spraying production line and management and utilization of server resources. The system includes:

[0008] Production line system module: It consists of one or more home appliance shell spraying production lines, industrial control systems and storage systems to realize the painting and warehousing of home appliance parts;

[0009] Data interaction module: It is composed of multiple switches and is used to realize data communication between the production line system module and the virtual machine server module and the upper control module;

[0010] Virtual machine server module: It consists of one or more virtual machine servers, standby virtual machine servers and corresponding workstations, which are used to integrate server resources. Each physical server can simultaneously virtualize different hardware environments and centrally run the production line industrial control system.

[0011] Upper control module: It consists of human-machine interface HMI, sequential control system SCS and database server, and is used to uniformly manage the operating status of the production line and server.

[0012] The production line system module includes an existing home appliance shell spraying production line or a newly built home appliance shell spraying production line and a corresponding storage system.

[0013] The industrial control system includes various versions of industrial computer operating systems, including Windows Server, Linux, and Windows operating systems.

[0014] The storage system includes a raw material warehouse, a finished product warehouse and a defective product warehouse.

[0015] Each virtual machine server of the virtual machine server module virtualizes different hardware environments according to actual production line requirements and runs industrial computer operating systems and software environments of different categories and versions.

[0016] The virtual machine server module performs hardware configuration on the virtual machine server and configures IP addresses according to the number and type of virtual machine systems running in the virtual machine server, so that hardware resources can meet actual use and achieve maximum utilization.

[0017] The upper control module controls and manages the home appliance shell spraying production line and the virtual machine server, and realizes the production scheduling, monitoring, decision-making of the home appliance shell spraying production line as well as the real-time monitoring and management of the storage system status and server resources.

[0018] Applying this system to achieve management includes the following steps:

[0019] Step 1: Integrate the home appliance shell spraying production line and the corresponding storage system to form a production line system module;

[0020] Step 2: Count the operating system or software versions of the industrial control system, determine the hardware environment in which it runs, and combine the actual operation of the production line to determine the operating environment that the virtual machine server needs to simulate and the number of virtual servers required;

[0021] Step 3: construct a virtual machine server module and determine the IP addresses corresponding to different physical environments of the primary and standby virtual machine servers;

[0022] Step 4: Configure the switch IP address, construct the data interaction module, and realize data communication between the production line system module and the virtual machine server module as well as the upper control module.

[0023] In the step 3, after respectively configuring the IP addresses of the primary and standby virtual machine servers, unified management of the virtual machine servers is achieved through the workstation computer.

[0024] Multiple WinCC servers of multiple home appliance shell spraying production lines are virtualized into the same main virtual machine server, and the backup virtual machine server configuration is the same as the main virtual machine server.

[0025] Compared with the prior art, the present invention has the following advantages:

[0026] 1. The present invention effectively solves the compatibility problem between server software and hardware, reduces maintenance costs, allows for rapid hardware maintenance and upgrades, and enables integration of server resources without worrying about compatibility issues with old systems.

[0027] 2. While ensuring the stable and efficient operation of the server, the utilization rate of server resources is improved, and virtual machine servers can be uniformly managed and configured, with strong scalability.

[0028] 3. It can realize intelligent management of multiple spraying production lines equipped with different industrial control systems, and realize real-time management and scheduling of production scheduling, monitoring, decision-making of home appliance shell spraying production lines, as well as storage system status, server and other resources.

[0029] 4. The virtual machine server has the characteristics of dynamic migration, disaster recovery backup, high-capacity storage, etc., and the installation of the virtual machine operating system and programs can be carried out through the virtual machine tool in the form of direct cloning or indirect migration, eliminating the cumbersome installation steps and saving time. When the virtual machine server system fails, the system operation can be restored in the shortest time, improving the system response speed. BRIEF DESCRIPTION OF THE DRAWINGS
