The invention is suitable for the technical field of signal detection, and provides a signal detection method and device and a terminal, and the method comprises the steps: obtaining a plurality of sampling values of a to-be-detected signal in a current detection period; if the first proportion is greater than a preset first threshold value, determining that the signal detection result of the current detection period is signal abnormality; wherein the first proportion represents the proportion of the number of times of abnormal sampling values in the current detection period to the preset total sampling number of times, and the preset total sampling number of times is determined based on the duration of the current detection period and the sampling frequency. The accuracy of a signal detection result can be improved. 本申请适用于信号检测技术领域，提供了一种信号检测方法、装置及终端，该方法包括：获取当前检测周期内对待检测信号的多个采样值；若第一比例大于预设第一阈值，则确定当前检测周期的信号检测结果为信号异常；其中，第一比例表示当前检测周期内的采样值异常的次数占预设总采样次数的比例，预设总采样次数基于当前检测周期的时长和采样频率确定。本申请能够提高信号检测结果的准确性。
