Abstract: At present, the manual patrol mode is widely used for distribution line inspection, which has such problems as time-consuming, poor quality, defect- omission, and error-prone records. To resolve these problems, a research is made on the multifunctional vehicle inspection technology with full-automatic tracking, and a distribution network vehicle inspection system is designed. The system uses the patrol vehicle as mobile platform, which is equipped with compound-eye probe of multifunctional detection module and vehicle control center based on intelligent edge algorithms. It can realize automatic line tracking, data synchronization acquisition, on-site analysis of defects, and real-time data transmission. The system has been applied in distribution lines inspection and all the functions have reached the expected objective.
