Sensor Array Based Distributed Instrument System
Keywords:components, distributed instrument, sensor array, virtual bus
The dynamic integration of sensors to design distributed instrument system is absorbing more and more research focus for its requirements in modern producing enterprises for low-cost products. In this paper, the distributed instrument based on sensor array 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 among sensors 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 sensors can be connected together dynamically. Based on the hardware concepts, the instrument components are proposed for data acquisition, data management, data processing etc.. The data exchange among instrument components can be configured according to the communication software bus. The measurement data from the distributed sensor array can propagate among the configured data logical flow ways asynchronously, and users can plug and unplug any components to the online instrument cases. Finally, the proposed application case is present which shows that the proposed way can accelerate the collaboration of production for different enterprise and improve the producing efficiency.
