Abstract
Traditional electronic multi-sensor electronic belt scale has no function of fault-tolerance. Aiming at the disadvantage
put forward a new method
which according to correlation among multiple path sensors
build up forecast network of fault sensors use radial basis function( RBF) neural network and combines the forecast signals with several other paths normal signals of sensors to complete belt scale weighting in condition that anyone sensor is in fault. Through simulation for simulated data
this method can effectively avoid measurement error produced by sensors fault.
