摘要:

针对无人飞行器在线路巡检过程中需要对线路进行识别、位置测量、避障、跟踪的需求,设计一种工频输电线路和设备检测与跟踪方法。系统包含被动式阵列磁感应天线装置、阵列扫描与采集控制电路、姿态与距离数据处理器3部分,被动式阵列磁感应天线装置作为磁场信息探测、检测环节,由扫描采集控制环节控制,实现磁场分布状态与强度信息的采集,再由后续数据信号处理环节解算出被探测高压输电线路的位置、距离等信息。最后,在ARM系列的STM32F104硬件开发平台上进行了验证,通过现场飞行测试,获得了较为满意的效果。

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 powerfrequency 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 followup data signal processing link can calculate the location, distance and other information of detected highvoltage transmission line. Finally, it is verified on the platform developed by the ARM series STM32F104 hard ware. Through the onsite flight test, the results turn out to be satisfying.
