Abstract
Sensory and adaptive access of manufacturing equipment (ME) is the key of physical resources virtualization in cloud manufacturing (CM). Three aspects including status sensory of ME, Internet of Things (IoT) and adaptive access of CM service platform were elaborated to analyze the characteristics and to investigate the related technologies. The importance of fiber Bragg grating sensing technology for ME sensory was analyzed. The heterogeneous fusion system and fusion access method as well as device of equipment resources were discussed. The access of ME resources for CM service platform was investigated based on three aspects including information fusion, description and retrieval and service release. Taking the realization of intelligent sensory and adaptive access for typical ME resources as an example, the prototype system, the sensory of ME resources and the realization of IoT of ME resources as well as the adaptive access method for CM service platform were expounded.
Highlights
Cloud manufacturing (CM) is a new kind of manufacturing method and technology which is serviceoriented, efficient, low consumption, and is based on the networked and agile knowledge, and it will promote the manufacturing to be agile, green and intelligent[1,2]
In CM architecture, the physical resources layer is at the bottom of the architecture and is the base of acquiring information of manufacturing resources and realizing management and invocation of CM resources service, and it is the premise of interaction of resources information in CM[3,4]
Sensory of various manufacturing equipment (ME) resources status information in CM will necessarily come into a heterogeneous network system with multiple access methods, multiple transmission rates and various service quality requirements
Summary
Cloud manufacturing (CM) is a new kind of manufacturing method and technology which is serviceoriented, efficient, low consumption, and is based on the networked and agile knowledge, and it will promote the manufacturing to be agile, green and intelligent[1,2]. Physical resources layer’s main task is to make all kinds of physical manufacturing resources access to the network to realize comprehensive interconnection and sharing of physical resources in CM, and to provide the interface of virtual encapsulation and service invocation of CM resources through a variety of advanced information and communication technologies. Sensory and access of physical manufacturing resources is the key to realize full sharing and seamless collaboration of equipment resources, especially in CM system for group enterprises. This paper conducts a comprehensive analysis of sensory and adaptive access technology of CM equipment resources from three aspects, including sensory of ME resources, IoT and adaptive access for CM service platform, and some specific applications are given to further explain the key implementation technology and method
