摘要:: 基于解决现代工业生产中复杂信号分析难题的目标，该研究采用了创新性的"双通道周期信号分离装置"。该装置在工业仪表、控制系统和传感器等领域广泛应用，能高效精准地分离多频率、多波形混合信号。面对工业环境中频率和波形多样的挑战，该研究结合STM32平台，成功实现对周期信号A和B的准确分离和还原。装置工作原理简明清晰，信号经过预处理模块消除直流成分后，经STM32智能核心板时域离散采样和傅里叶变换等处理，实现对信号频谱特征的识别。信号再构模块则采用频率相位可编程信号发生器，对信号进行再构，最终实现双通道周期信号的精确分离。经过实验测试，装置在叠加信号测试中表现出色，成功分离多种信号组合，验证了其高效性与精确性。

Abstract:: In the pursuit of addressing the intricate complexities in signal analysis within contemporary industrial manufacturing, this study introduces an innovative solution – the "Dual-Channel Periodic Signal Separation Device." This apparatus finds widespread utility across industrial instrumentation, control systems, and sensing applications, efficiently and accurately dissecting amalgamated signals of diverse frequencies and waveforms. Confronting the multifaceted challenges posed by varying frequencies and waveforms in industrial contexts, this investigation synergizes the STM32 platform to successfully achieve precise separation and reconstitution of periodic signals A and B. The operational mechanism of the device is presented succinctly and lucidly: signals undergo a preprocessing stage to eliminate direct current (DC) components. Subsequently, via STM32’s intelligent core board, temporal-domain discrete sampling and Fourier transformation are employed to discern the spectral attributes of the signal. The signal reconstruction module capitalizes on a programmable frequency-phase signal generator, orchestrating signal reconstitution and ultimately attaining meticulous dual-channel periodic signal separation.
