The invention relates to a charging pile noise reduction method, device and system in the technical field of noise reduction, and the method comprises the following steps: setting a plurality of groups of noise source collection points, and obtaining mixed noise at each group of noise source collection points; separating each group of mixed noise into a plurality of groups of original single noise; acquiring playing delay time corresponding to each group of original single noise, and generating mixed noise reduction noise based on the playing delay time; when the charging pile operates, the mixed noise reduction noise is played at the same time, the noise reduction cost is low, and the bottleneck that a mixed noise source cannot achieve effective noise reduction is broken through.

    本发明涉及降噪技术领域中的一种充电桩降噪方法、装置和系统,包括以下步骤:设定若干组噪音源收集点,并获取每组噪音源收集点处的混合噪音;将每组混合噪音分离为若干组原始单噪音;获取每组原始单噪音对应的播放延时时间,并基于播放延时时间生成混合降噪噪音;当充电桩运行时,同时播放混合降噪噪音,具有降噪成本低的优点,突破了混合噪音源无法实现有效降噪的瓶颈。
