Faults in mechanical equipment could cause breakdown of time-critical production systems, which is very expensive in terms of production losses and re-commissioning costs. In cloud manufacturing, the scattered distribution of mechanical equipment and fault diagnosis resources, such as experts and specialist instruments, etc., could hinder the development of fault diagnosis systems. The idea of resource...
Cloud Computing and Internet of Things are the buzzwords after Web 2.0. Cloud Computing, as a large-scale distributed computing paradigm, is a recent trend in IT that delivers applications as services over the Internet. The Internet of Things (IoT), as the future network of Internet, refers to a dynamic global network infrastructure in which physical and virtual “things” are seamlessly integrated...
After investigated the conception and features of PLC (Programmable Logic Controller) and embedded system, in this paper the conception of Quasi-PLC are proposed, which combine the advantages of PLC and embedded system. The architecture of Quasi-PLC and a Top-Down design method with collaboration design of software and hardware for Quasi-PLC embedded control system are researched then. Finally, setting...
With the increasingly severe global market competition, the nature of enterprise competition has changed from competition among enterprises into the competition among supply chains. Lowering operating costs of the supply chain and responding to market quickly have become the main objectives of the supply chain management (SCM). The emerging grid workflow technology which can integrate heterogeneous...
A supply chain (SC) is a world-wide complex network of suppliers, factories, warehouses, distribution centers and retailers. Due to the features of its production planning: distribution, autonomy, synchronism and openness, the traditional methods of production planning are unable to meet the demands of supply chain production planning (SCPP). Under collaborative environment, in order to eliminate...
This paper investigated the development history of fault diagnostic technology for equipments, especially remote fault diagnostic system based on Internet and Web technology in detail. Then, this paper proposed a framework of remote fault diagnostic system based on emerging Grid technology to enable coordinated resource sharing and problem solving among multiple equipment suppliers and equipment users,...
The authors analyze the new requirements of the numerical control (NC) in network environment at present and propose a novel architecture of the network NC (NNC). In this architecture, the service-oriented NC system based embedded technology is the core part, providing abundant functions and more diversified processing abilities through networks. Both the hardware and software structures of the service-oriented...
Manufacturing information (MI) plays an essential role in modern digital manufacturing technologies, and it includes all the information referring to the manufacturing activities. The traditional MI sharing models cannot be used in an extensible and flexible application, and also dwell little on the performance issues in MI sharing. In this paper, we begin with analyzing the differences between MI...
Industry has put forward demands on cross enterprises collaboration including various resources sharing. A service-oriented networked numerical control system for sharing information between business partners through the Internet infrastructure is presented in this paper. The paper describes the existing problem of the current numerical control system and brings forth the conception of SoNNC. This...
Most manufacturing companies have realized that the ability to quickly develop a customized product through an economic and efficient way is critical for them to survive in the keen competitive global market. In order to shorten the lead time to market, the product design and manufacturing requires designers and engineers from different departments of the enterprise to work together within a collaborative...
