Abstract:

Addressing the need of identification, position measurement, obstacle avoidance and tracking in the process of unmanned aerial vehicle inspection, a detection and tracking method for powerfrequency transmission line and equipment is designed. The system includes passive array magnetic induction antenna device, array scanning and acquisition control circuit, attitude and distance data processor. The passive array magnetic induction antenna device is used as the magnetic field information detection and testing link. It is controlled by the scanning and acquisition control link to collect the magnetic field distribution and intensity information. Then, the followup data signal processing link can calculate the location, distance and other information of detected highvoltage transmission line. Finally, it is verified on the platform developed by the ARM series STM32F104 hard ware. Through the onsite flight test, the results turn out to be satisfying.
