【摘要】针对现有异常信号传输延迟消除方法生命周期较短且延迟消除效率较低的问题,提出了一种煤矿机电监控系统异常信号传输延迟消除方法。该方法采用FIR数字滤波器对异常信号进行滤波,进而检测异常信号传输延迟;利用动态树构建异常信号聚集树模型,对未经过延迟消除的信号进行标记,计算所有经过标记的信号的时槽,挑选出时槽最小的信号,对信号进行延迟消除。仿真结果表明,该方法生命周期长,且消除异常信号传输延迟的效率较高。
【Abstract】In view of problems of short life cycle and low delay elimination probability of existing abnormal signal transmission delay elimination methods, a transmission delay elimination method of abnormal signal in coal mine electromechanical monitoring system was proposed. In the method, FIR digital filter is used to filter abnormal signal and then detect abnormal signal transmission delay. Abnormal signal aggregation tree model is constructed by use of dynamic tree to mark signal that has not been eliminated by delay, calculate time slot of all marked signals, select signal with the smallest time slot, and eliminate delay of the signal. The simulation results show that the proposed method has a long life cycle and high efficiency in eliminating abnormal signal transmission delay.
