Abstract

The invention discloses a device for measuring resonance intensity of land mine. The device includes a signal generator, a sound console, a power amplifier and a loudspeaker, wherein the signal generator is connected with the sound console, the power amplifier and the loudspeaker sequentially through leads to form a sound wave emission system. The device further includes a seismic detector, a data acquisition card and a computer, wherein the seismic detector is connected with the computer via the data acquisition card through a data line to form a ground surface vibration speed detection system. A method for measuring resonance intensity of the land mine by using the device particularly comprises the following steps of: 1) detecting and calculating a ground surface vibration speed amplitude-frequency characteristic curve under the condition without the land mine; 2) detecting and calculating a ground surface vibration speed amplitude-frequency characteristic curve under the condition with the land mine; and 3) evaluating a specific value of the two curves in the steps to acquire a ground surface vibration speed relative value amplitude-frequency characteristic curve under the conditions with and without the land mine. By the measuring device and the measuring method, the resonance intensity of the land mine can be measured precisely and quickly.

Description

Technical field [0001] The invention involves the field of detection technology of shallow underground flexible burials, especially a kind of mines and measuring device and measurement method.Measurement device and method. Background technique [0002] So far, the safety and reliable detection of non -metal mines such as plastics is still a worldwide problem.The usual metal mineforeer can only detect metal mines based on the principle of electromagnetic induction. The detection effect of non -metal mines such as plastic with little metal content is very poor.For imaging technologies based on infrared, ground radar, X -rays, it is difficult to distinguish the detection mechanism to distinguish the buried objects as mines or rocks, bricks, or other fragments;Non -imaging technologies such as and thunder grass, etc. are still in the stage of exploration or application of feasibility argumentation. [0003] The sound resonance detection technology based on moring mechanical character...
