2-D Bar Code Technology Based Substation Patrol Robot’s Visual Navigation

The development of robot technology and AI makes it possible using outdoor mobile robots inspecting substations instead of manual work [. To solve the technical problems of substation patrolrobots navigation, a general scheme of substation intelligent inspection based on the red guide line is put forward. The 2-D bar code records main inspected equipments information, aiding patrol robot positioning navigation. The system utilizing LabVIEW virtual instrument software with IMAQ Vision module has been successfully written and related to pictures image processing, detecting and reading 2-D bar code. It has practical significance to improve the efficiency and to enhance the portability and flexibility of substation inspection scheme.
