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...
A coordination and control approach for task allocation is proposed in this paper, aimed at handling static task allocation and dynamic changes and disturbances. This coordination and control approach uses an indirect coordination mechanism, called pheromone, which comes from the collective behavior of ant colonies for food foraging. This approach has the capacity for task allocation model to automatically...
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...
So far, methods of fault diagnosis have been numerous. But as the complexity of modern equipment, the variability of fault, as well as trends in global manufacturing, it is difficult for any separate organization of independent to complete all the work of fault diagnosis. This article reviewed the equipment fault diagnostic technology in the course of development, in particular, remote fault diagnostic...
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,...
