Abstract:
According to the traditional GPS equipment failure in the process of mining, it is very vulnerable to external
nonlinear strong multiplicative noise interference, made in fault mining process, appear larger error, cause trouble the ac原
curacy of the calculation is not high. In order to solve this problem, puts forward the multiplicative noise interference of
the GPS equipment failure mining method, through the precise analysis of the multiplicative noise reasons, accurate anal原
ysis of noise characteristics, using the fault signal of the piecewise fitting mechanism, eliminate redundant under the in原
terference failure characteristics of miscellaneous problems. So as to avoid the defects of the traditional metho
