Research on Algorithm of Multi-Sensor Redundance Based on Neural Network

Combining the hardware redundant technology with BP neural network and Elman recurrent neural network, the paper presents a new method for constructing an intelligent sensor system with abilities of sensor fault detection, fault isolation and redundancy. With the method, the number of sensors used in the hardware redundant technology can be reduced, the demands for the sensors with the same parameter properties can be ignored and at the same time the prediction accuracy for system output also could be improved. The result of simulation for a real temperature control system show that the method is correct and practicable.
