摘要
鉴于传统瞬变电磁探测系统同步方式不适用于半航空无人机瞬变电磁勘探系统,提出一种基于信号峰值检测的瞬变电磁同步技术,并利用Labview2012开发了信号峰值检测程序及双极性叠加程序,在实验室通过对模型实际探测来对算法进行检验:通过对单测点重复测量,验证同步叠加的稳定性;通过对单测线低阻模型的实际探测,验证算法的准确性。实验测试表明,基于二次感应电压峰值检测的同步方式,在不增加无人机起飞重量的同时,能够保证同步叠加的稳定性和探测的准确性,适用于无人机空地瞬变电磁探测。
In view of the fact that the synchronization mode of the traditional transient electromagnetic detection system is not suitable for the transient electromagnetic detection system with semi-aviation pilotless plane,a transient electromagnetic synchronous technology based on signal peak detection was proposed. The peak detection procedure and the bipolar superposition program were developed by Labview2012,and the algorithm was tested by the actual detection of the model in the laboratory; the stability of the synchronous superposition was verified by the repeated measurements at a single measurement point; and the accuracy of the algorithm was verified by the actual detection of the low resistance model in a single testing line.The experimental tests showed that the synchronous mode based on the secondary sensing voltage peak detection can ensure the stability of the synchronous superposition and the accuracy of detection without the increase of the takeoff weight of the pilotless plane. Therefore,it is suitable for the air-to-ground transient electromagnetic detection with pilotless plane.
