Passive type array magnetic induction antenna device

Abstract

The present invention discloses a passive type array magnetic induction antenna device. The passive type array magnetic induction antenna device comprises a substrate; a driving circuit, a voltage stabilizing circuit, a resonant sampling circuit and a plurality of magnetic induction sub-units are arranged on the substrate; the plurality of electromagnetic induction sub-units are arranged uniformly in an arrayed manner; the driving circuit includes a line total driving circuit, M line driving circuits, N column driving circuits and M*N AND gate circuits; and the magnetic induction sub-units are in one-to-one correspondence with the AND gate circuits. According to each pair of coils, two orthogonally distributed 10mH inductors are connected in series to form a matrix array; the coils are fixedly welded onto the substrate through two wire terminals; the substrate can serve as a fixing plate for the coils and can also converge and connect the connection lines of each coil to a socket, and therefore, the coils can be installed at the front of an unmanned aerial vehicle; whether a power transmission line exits can be induced in real time through the passive array inductance coils, and the distance information and position angle information of the aircraft relative to the power transmission line can be further induced; and a basis for discrimination can be provided for a follow-up signal processing circuit.

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 a power system, in particular to a passive array magnetic induction antenna device. 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 perform regular i...
