Abstract	本申请适用于电子信息设备技术领域，提供了一种非侵入式流量测量方法及装置，其中该方法包括：基于毫米波传感器采集液面反射毫米波信号；按照待检测的流体的液面方向，将所采集的液面反射毫米波信号拆分为相应的垂直液面信号分量和平行液面信号分量；根据液面反射毫米波信号的垂直液面信号分量和预设夹角，确定待检测的流体的液位深度信息；根据液面反射毫米波信号的平行液面信号分量和预设夹角，确定待检测的流体的液面流速信息；根据所确定的液位深度信息和液面流速信息，确定待检测的流体的目标流量信息。由此，可以实现在各种流体场景下直接非侵入式地测量流体的流量。
Other Abstract	The invention is suitable for the technical field of electronic information equipment, and provides a non-invasive flow measurement method and device, and the method comprises the steps: collecting aliquid level reflection millimeter wave signal based on a millimeter wave sensor; according to the liquid level direction of the fluid to be detected, splitting the collected liquid level reflection millimeter wave signals into corresponding vertical liquid level signal components and parallel liquid level signal components; determining liquid level depth information of the to-be-detected fluid according to the vertical liquid level signal component of the liquid level reflection millimeter wave signal and a preset included angle; determining liquid level flow velocity information of the to-be-detected fluid according to the parallel liquid level signal component of the liquid level reflection millimeter wave signal and a preset included angle; and determining target flow information of the fluid to be detected according to the determined liquid level depth information and liquid level flow velocity information. Therefore, the flow of the fluid can be directly measured in a non-invasive manner in various fluid scenes.
