Amplitude-frequency electric perspective detection method

The invention discloses an amplitude-frequency electric perspective detection method and belongs to a bottom plate detection technology of the working surface. A plurality of launching points and receiving points corresponding to the launching points are arranged in a launching laneway and a receiving laneway respectively, and the aquosity of a bottom plate of the working surface is detected by adopting a point-by-point launching and group-by-group receiving mode in an area composed of the launching points and the corresponding receiving points. A launching device and a receiving device are in independent split type, a timing and constant-current power supply working method is adopted, the number of detection devices and required detection workers is reduced, the labor intensity of the detection workers is reduced, the working efficiency and the quality of data obtained by detection are greatly improved, the technical effect in the aspect of evaluation of the whole aquosity of the bottom plate of the working surface is extremely obvious. Besides, two detection signals which are a high-frequency signal and a low-frequency signal can be adopted in the method simultaneously, contrast detection is performed according to the detecting environment conditions, optimal working parameters are selected preferably, and the detecting working effect is guaranteed.
