Bluetooth Technology In Industrial Control Applications

First this paper expatiates the hierarchical protocol architecture of Bluetooth?technology, introduces and analyses Bluetooth?Radio Frequency, Link Controller and Baseband, Link Management Protocol, Logical Link Control and Adaption Protocol, Service Discovery Protocol, RFCOMM and so on, which illuminates the characteristics and applied conditions. In the second section I summarize the developing history, characteristics and class of Fieldbus technology. As the third section is related with Foundation Fieldbus, the characteristics, architecture and Function Block of it is expatiated in this section. In the third section, I discuss the disadvantages of using wire media as physical layer media in traditional Fieldbus on the basis of the first two section, and present a solution of substituting wireless Bluetooth?for wire media. In this solution the Bluetooth?gateway is presented by integrating Bluetooth?and Fieldbus, the data collected by Bluetooth?sensor is transported to FF HSE Fieldbus by Bluetooth?gateway, and the control logic of FF HSE Fieldbus is realized by the same Bluetooth?gateway. The Bluetooth?gateway interconnectes wire FF HSE Fieldbus and wireless Bluetooth?Piconet, and the analysis and development of Bluetooth?gateway is expatiated in this section. As the conception of Bluetooth?gateway is presented for the first time, it is innovational.
