Abstract

An integrated monitoring, control and shut-down (IMCS) system for monitoring and controlling the operation of a machinery is provided. The IMCS system includes: input ports for receiving sensor signals indicative of conditions of the machinery, output ports for outputting control signals to actuators of the machinery, signal conversion means coupled to the input and output ports, for converting the input sensor signals into data samples and for converting control data into control signals. The IMCS system also includes a data processor for controlling the signal conversion means, for processing the data samples into calculated values, for sending selected calculated values to be stored into a memory and for calculating control data. A communication bus couples the hardware elements of the IMCS system. The invention can be used for monitoring, controlling, diagnosing and determining the performance of machines used to develop mechanical energy such as reciprocating engines, machines driven by a rotating shaft such as electrical generators, rotating and reciprocating compressors, rotating and reciprocating pumps, propellers (air and water), water and gas turbines, and the like. A data acquisition process for use in the monitoring and control of a rotating equipment comprising a shaft is also provided. The method comprising the steps of sampling a condition sensor output indicating a condition of the rotating equipment that requires monitoring, sampling a marker sensor indicating the rotational position of said shaft and combining the condition signal and the rotation marker signal.
