摘要：针对传统的GPS设备故障挖掘过程中,很容易受到外界非线性很强的乘性噪声的干扰,使得在故障挖掘的过程中,出现较大的误差,造成故障计算的准确性不高。为了解决这一问题,提出了乘性噪声干扰下的GPS设备故障挖掘方法,通过准确分析乘性噪声产生的原因,准确分析噪声特征,运用故障信号的分段拟合机制,排除冗余干扰下的故障特征冗杂问题,从而避免了传统方式的缺陷。实验证明,优化方式能够提高GPS设备故障检测的准确性,取得了令人满意的效果。
According to the traditional GPS equipment failure in the process of mining, it is very vulnerable to external nonlinear strong muhiplicative noise interference, made in fault mining process, appear larger error, cause trouble the accuracy of the calculation is not high. In order to solve this problem, puts forward the muhiplicative noise interference of the GPS equipment failure mining method, through the precise analysis of the multiplicative noise reasons, accurate analysis of noise characteristics, using the fault signal of the piecewise fitting mechanism, eliminate redundant under the interference failure characteristics of miscellaneous problems. So as to avoid the defects of the traditional method. Experimental results prove that the optimization methods can improve the accuracy of the GPS equipment fault detection, and achieved satisfactory effect.
