Abstract
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.
Highlights
Measurement technologies that serve as the important parts of industrial production tend to be updated and changed many times during their lifetime [1]
To assemble the components together to enjoy the needs of the measurement tasks, the configuration protocols must be used to allow the specification of the measurement system and the definition of instrument component interaction [8,9,10]
The novel idea of this paper is put a high premier on sensor array distributed in the web environment, instrument components and virtual bus, which can integrate the measurement instrument components dynamically according to the measurement tasks
Summary
Measurement technologies that serve as the important parts of industrial production tend to be updated and changed many times during their lifetime [1]. Based on the modern production situation, the running measurement systems must be reconfigured without interruption of their execution to achieve automatic reconfiguration and the process only works in the current application as the result of some computation performed by the platform working mechanism. The novel idea of this paper is put a high premier on sensor array distributed in the web environment, instrument components and virtual bus, which can integrate the measurement instrument components dynamically according to the measurement tasks. Based on the proposed way, all the instrument components can exchange data on the uniform virtual data bus sequence asynchronously. In this way, the measurement tasks can be reconfigured on the executing interfaces which change the measurement structure of the system dynamically and flexibly.
