[Abstract]:With the development and maturity of various core technologies of cloud computing, cloud manufacturing technology has emerged in the manufacturing field. Cloud manufacturing is a new manufacturing model based on cloud computing, which is still in the primary stage of development. How to build cloud manufacturing service platform and provide various manufacturing resource services for distributed customers is still in the preliminary research and development stage. This paper analyzes the computer integrated manufacturing, application service providers, Combined with cloud computing technology, the architecture of cloud manufacturing and the functional requirements of cloud manufacturing service platform are studied. This paper puts forward the basic requirements of resource access and the access methods of some resources. Using the core technologies of cloud computing virtualization and SaaS, the virtual machine cluster and virtual desktop pool are established in V13 environment. Some software and hardware resources are encapsulated by using virtualization technology, and a preliminary cloud manufacturing prototype system based on Web is constructed in X86 environment, and a distributed database system and a real-time database system are constructed based on the secondary development of MySQL. With the help of database and Google File system (GFS) technology, a task decomposition model based on historical task statistics and a method of resource management and resource matching scheduling based on cloud manufacturing platform are developed. Some effective management and remote sharing of cloud manufacturing resources are realized. The chapters are arranged as follows: the first chapter introduces the source of this paper, the main research contents of the subject, and briefly describes the domestic and foreign research status and development trends in related fields. Finally, the main research contents and organization structure of the thesis are introduced. Chapter 2 analyzes the functional requirements of cloud manufacturing service platform, and proposes five supporting modules: Web end service support module. Business mode and platform supervision support module, task decomposition support module, resource call platform support module, resource encapsulation support module, In the third chapter, some key technologies of cloud manufacturing system are analyzed, and the encapsulation specification, representation method and access method of resources are analyzed and put forward. The task decomposition model based on historical task statistics and the resource management and matching scheduling method based on database table are put forward, the virtualization technology is analyzed, and some virtualization encapsulation methods of software and hardware resources are proposed. This paper introduces the virtual machine cluster technology and the service form and technology of Web. Chapter 4 studies the building method of cloud manufacturing prototype system, the cluster of virtual machines and the building method of virtual desktop pool, which support cloud manufacturing prototype system. The distributed database system and the real time database system are constructed by using MySQL as the background support database of the cloud manufacturing prototype system. In chapter 5, taking a motor development process as an example, we demonstrate some examples of resource sharing service in cloud manufacturing prototype system. The sixth chapter summarizes the research work and results of this thesis, and points out the future work of cloud manufacturing prototype system in this paper.
