A multiple DSP environment for on-line signature analysis of plant instrumentation

A system consisting of four parallel digital signal processors that communicate with a computer host is proposed for implementing online fault detection and identification using industrial transducers. Programming of the fault detection algorithms is carried out in a block-diagram graphical language, specially designed for that purpose. The programming environment allows automatic program segmentation into parallel tasks, the generation of the corresponding code, the allocation of the coded tasks to the four processors, and simulation of the operation of the programmed system. An example (a turbine flow meter) is given to demonstrate the use of the software.<>
