第30届中国控制与决策会议

作者： Guicheng Wang Jin Wu Xin Li Ran Mo Min Zhang Shanghai Institute of Technology

According to the needs of real-time tracking maneuvering targets, by introducing the tracking principle of maneuvering target, the Gaussian algorithm and wavelet filtering are combined to remove the influence of interference, and the data of the maneuvering target is subjected to data fitting and landing site prediction analysis to obtain the target maneuvering trajectory and find the coordinates of the target location. Simulation results show that the real-time tracking method can effectively track the maneuvering target and basically achieve the goal of target tracking.

RFID Based e-quality tracking in Service-oriented Manufacturing Execution System

Chinese Journal of Mechanical Engineering 2012年第5期25卷 974-981页

作者： FU Yingbin JIANG Pingyu State Key Laboratory for Manufacturing Systems Engineering Xi'an Jiaotong UniversityXi'an 710049China

The method of acquiring the real-time data has influenced the implementation of the manufacturing execution system （MES）. Accompanied with turning the MES into service-oriented manufacturing execution system （so-MES）, real-time e-quality tracking （e-QT）, in which real-time data are computed, has played more and more important roles in manufacturing. This paper presents an e-QT model through the study of real-time status data tracking and quality data collecting. An implementing architecture of the e-QT model is constructed on the basis of radio frequency identification devices （RFID） data-tracking network. In order to develop the e-QT system, some key enabling technologies, such as configuration, data collection, and data processing, etc, are studied. The relation schema between hardware is built for the RFID data-tracking network based on the configuration technique. real-time data are sampled by using data collecting technique. Furthermore, real-time status and quality data in a shop-floor can be acquired in terms of using the real-time data computing method. Finally, a prototype system is developed and a running example is given so as to verify the feasibility of methods proposed in this paper. The proposed research provides effective e-quality tracking theoretical foundation through the use of RFID technology for the discrete manufacturing.
