自适应相干模板法在信号检测系统中具有广泛应用，该算法可同时滤除工频干扰和基线漂移、。但在工频频率不断波动的采集系统中，该算法的滤波效果明显变差。介绍了一种双线程模式实时跟踪工频干扰的自适应相干模板法及该算法在LabVIEW上的实现过程。实验证明，该算法通过在LahVIFW上的实现，能够快速实时跟踪和滤除工频干扰，且效果明显。

Adaptive coherence model has been widely used in signal detection systems and it can simultaneously reject the power-line interference and baseline wander. But the filter effect for this algorithm becomes worse obviously in the acquisition system under a vulnerable power-line interference. This paper introduces a method of double thread model tracking power-line interferene adaptive coherent template method and its realization on the LabVIEW. Experiments have proved that this method based on the LabVIEW can achieve real-time tracking and rejecting power-line interference efficiently.
