Paper Abstract

This paper presents a proposal for an optical gas monitoring system based on fieldbus. With the help of the advanced signal processing system more than one hundred gas detectors can be connected to a host system by a single shared bus cable over which the gas detectors, now incorporating with their own intelligence, communicate digitally with the host system. The new system supplies not only about the gas level but also about the physical condition of each sensor. Planed maintenance can be performed to ensure that gas monitor system is maintained in full working order. Integrating fieldbus with optical gas sensor will also have dramatic saving in field wiring and the man-hours for system verification and configuration.
