Circuit breaker multipath vibration sensor signal optimization method and system

The invention discloses a circuit breaker multipath vibration sensor signal optimization method and system. The method comprises the following steps: firstly, collecting multi-path sensor vibration signals of a circuit breaker, and determining one path of signal as a reference signal and the other paths of signals as comparison signals; secondly, calculating dynamic coefficients and single correlation degrees of all multi-path signals, and then calculating dynamic comprehensive correlation degrees of a current reference signal relative to all other comparison signals; and finally, calculating to obtain the dynamic comprehensive correlation degree of each path of sensor vibration signal relative to other multi-path signals, and taking the maximum dynamic comprehensive correlation degree as the optimal signal in the multi-path sensor of the circuit breaker. According to the method, the optimized signals are obtained through calculation of the dynamic correlation indexes, the accuracy of signal optimization is i
