Abstract: Aiming at the problems of large coal-fired units in domestic thermal power industry, such as the lack of fieldbus technology advantages, the improvement of maintenance efficiency of thermal control equipment and the realization of condition-based maintenance of equipment, this paper designs a complete set of technical applications from the construction and installation of system equipment, communication quality monitoring, remote adjustment of basic parameters, to the final account establishment, early fault warning and data statistical analysis. The scheme solves the deep application problem of Fieldbus Technology in large coal-fired thermal power units,achieves the functions of remote maintenance, fault diagnosis and predictive maintenance of thermal control equipment, and provides an important reference for popularizing the application of Fieldbus technology.

Key words: Field bus; Profibus; Guided wave radar; Datum;Damping; Depth application
