The invention relates to a method for detecting a change in a region of a transport system to be monitored. For this purpose, the transport device has a sound sensor and an evaluation unit connected to the sound sensor. The method is characterized in that an acoustic pulse (62) is emitted into the region to be monitored, an acoustic response signal of the pulse (62) is recorded as an actual signal (64), an envelope curve (66) of the actual signal (64) is determined, and a change is identified on the basis of the envelope curve (66).
示出一种用于识别运送设备的待监测区域中的变化的方法。为此,所述运送设备具有声音传感器和与声音传感器连接的评估单元。该方法的特征是:发射声学脉冲(62)到待监测区域中,记录脉冲(62)的声学响应信号为实际信号(64),确定实际信号(64)的包络曲线(66),基于包络曲线(66)识别变化。
