The authors present the design of a prototype device that implements a redundancy management scheme for the on-line detection and isolation of faulty sensors in strategic facilities like nuclear reactors, hazardous chemical plants, aircraft, and spacecraft. Such a device is potentially useful for reducing the number of display devices in the control room and relieving the plant operator(s) from the tasks of assimilation and analysis of redundant sensor data as well as for enhancing the processing capabilities of the main computer. The device was built using an 8-bit microcomputer system and commercially available electronic hardware. The software is not restricted to any specific hardware; it is completely portable. The operation of the prototype device was successfully demonstrated for real-time validation at an operating nuclear reactor.
