摘　　要：无人机飞行巡逻检测系统受外界环境影响,信号衰减趋势与实际情况不一致,导致数据丢包率较高,为此提出基于移动小波树的电力线路缺陷远程检测系统设计。使用STM32F103ZE主控芯片的现场转发器,传递电流、温度数据给上位机。利用GTM900-C芯片设计GPRS通信模块,将信息发送到指定号码。使用无人机采集子系统,采集电力线路缺陷数据。通过地面站控制子系统,识别输电线路存在的问题。依据电力线程缺陷远程检测程序,建立移动小波树数据结构,批量更新数据。针对不同数据流长度进行聚集计算,直到发现异常位置为止。由实验结果可知,该系统检测到的信号衰减趋势与实际情况一致,最高丢包率为0.95%,对无人机飞行巡逻检测具有重要意义。The UAV flight patrol detection system is affected by the external environment,and the signal attenuation trend is inconsistent with the actual situation,which leads to high packet loss rate.Therefore,a remote detection system for power line defects based on mobile wavelet tree is proposed.The field repeater of STM32F103ZE is used to transfer the current and temperature data to the upper computer.The GPRS communication module is designed by using GTM900-C chip to send the information to the designated number.UAV acquisition subsystem is used to collect data of power line defects.Through the ground station control subsystem,the problems of transmission line are identified.According to the power thread defect remote detection program,the mobile wavelet tree data structure is established to update the data in batch.Aggregation calculation is carried out for different data stream lengths until the abnormal position is found.The experimental results show that the signal attenuation trend detected by the system is consistent with the actual situation,and the highest packet loss rate is 0.95%,which is of great significance for UAV flight patrol detection.
