Dynamic integration oriented data exchange methods for distributed instrument

The dynamic integration of measure resources in the distributed environment is absorbing more and more research focus for its requirements in modern producing enterprises for low-cost products. In this paper, the data exchange methods for distributed instrument is proposed, and the data exchange model is discussed which implemented the communication of the modules of the measurement instrument. And then the control mechanism of the data exchange is studied which manages the information of the measurement components and schedules the data process in the measurement cases. In this way, a group of measurement components and the distributed measurement units can be connected together dynamically. Based on the hardware concepts, the measurement component is proposed for instrument component design. The data exchange patterns among measurement components can be configured according to the communication address of software bus. The measurement data can propagate among the configured data logical flow ways asynchronously, and users can plug and unplug any components to the measurement platform. Finally, the proposed reconfigurable measurement example is present. The application case shows that the proposed way can accelerate the collaboration of production for different enterprise and improve the producing efficiency.
