Visualization of RFID enabled shopfloor logistics Big Data in Cloud Manufacturing
Cloud Manufacturing twining with Internet of Things (IoT) has been waked up to achieve final intelligent manufacturing. With the IoT technologies such as radio frequency identification (RFID) implemented in manufacturing sites, enormous data will be generated. Such data are so complex, abstract, and variable so that it is difficult to make full use of the data which carry great myriad of useful information and knowledge. This paper presents a visualization approach for the RFID enabled shopfloor logistics Big Data from Cloud Manufacturing. An innovative RFID Cuboid model is used for reconstructing the RFID raw data given the production logic and time series. Several contributions are highlighted. Firstly, a possible approach to integrate IoT and Cloud Manufacturing is introduced to upgrade and transform the traditional industry for an intelligent future. Secondly, an RFID Cuboid model is proposed by using the production logic and time stamps to chain the RFID data so that the data could be interpreted. Thirdly, a real life case is reported to show the feasibility and practicality of the proposed visualization approach to help different end users to ease their daily operations. Lessons and insights from this case are meaningful for the implementation of IoT enabled Cloud Manufacturing and Big Data analytics in industry field.
