摘 要：Abstract：The invention discloses a method for multi-directional collection of acoustic vibration signals of a pressure fluid pipeline. A tested pipeline body is included. The method for multi-directional collection of the acoustic vibration signals of the pressure fluid pipeline is characterized in that a sensor is at least arranged on the tested pipeline body, the sensor at least can sense the acoustic vibration signals in two directions, and the two sensing directions are perpendicular to each other; the plane formed by the two sensing directions is recorded as a monitoring plane, and the monitoring plane is parallel to the axial direction of the tested pipeline body; the sensor is used for detecting the acoustic vibration signals on the tested pipeline body and outputting detection signals outwards. The method for multi-directional collection of the acoustic vibration signals of the pressure fluid pipeline has the advantages that the detection area of a single collecting point can be expanded, the setting density of the collecting points is lowered, cost is saved, the signal to noise ratio of the signals can be improved, and the leakage point positioning precision is high in leakage detection.
