Embodiment Construction

[0035] Such as Figure 1-5 Shown, the present invention comprises the steps:

[0036] Step A: Use the array scanning and acquisition controller to control and acquire the passive array magnetic induction antenna device set by a plurality of electromagnetic induction sub-unit arrays: choose an electromagnetic induction sub-unit as the sampling start, and the array scanning and acquisition controller Control the high-speed analog-to-digital converter to sample the passive array magnetic induction antenna device continuously at a sampling rate with a frequency of U (then the period is 1 / U), and form a data frame with the collected N data, and convert the obtained data frame Sent to the array scanning and acquisition controller in turn; the array magnetic induction antenna device includes a substrate, and the substrate is provided with a drive circuit, a voltage stabilizing circuit, a resonant sampling circuit and a plurality of magnetic induction subunits, and the array of the pl...

Abstract

The invention discloses a method for array signal filtering and amplitude detection. Data sampling is performed on each electromagnetic induction sub-unit in a passive array magnetic induction antenna device through a high-frequency analog-to-digital converter, and multiple data are integrated into one data frame. Judgment of extreme value and zero point to determine whether the data frame conforms to the data of extreme value or zero point, if not, continue to judge the data of the next data frame, otherwise, extract the amplitude of the current data frame and save the amplitude Afterwards, the amplitudes of the remaining electromagnetic induction sub-units are sequentially extracted, and the overall scanning period is short, and the accuracy of amplitude extraction can be greatly improved by further collecting data near the extreme values.

Description

technical field [0001] The invention relates to the technical field of automatic detection of aircraft line inspection in the power transmission and distribution industry of electric power systems, in particular to a method for array signal filtering and amplitude detection. Background technique [0002] At present, the maintenance, inspection and emergency repair of transmission lines by power companies are still basically divided into sections, relying on manual on-site inspections of line inspections. The timeliness and accuracy of line defect discovery depend on the professional ability and responsibility of line inspectors and the implementation of inspection and inspection by team managers, and the occurrence of various accidents caused by insufficient inspection cannot be eliminated. At the same time, some transmission lines are erected in deep forests, wetlands, and high mountain areas. The arrival of personnel is slow, difficult, and inefficient. It is impossible to...
