Design Of Factory Patrol System Based On Quad-rotor Unmanned Aerial Vehicle

For the traditional factory safety inspection by the manual implementation which has some problems such as heavy workload,poor quality,data management is prone to be error.This paper designs a factory safety patrol system based on the DJI M100 UAV development platform.The unmanned aerial vehicles can inspect the factory autonomously,at the same time,the inspection data would be managed by the host computer software.The system has a practical significance in protecting the factory production and achieving information management of enterprise.Firstly,based on the analysis of plant safety requirements,this paper proposes the overall design of the security patrol system based on four aspects of system workflow,system hardware foundation,airborne control software and host computer software.Secondly,this paper designes the airborne control software which can make the UAV achieve self-inspection.It realizes UAV 's autonomous cruise based on GPS Navigation and Path Tracking Navigation,it realizes indoor positioning based on road marking method.The auxiliary cruise method is also designed to improve the intelligence of the UAV.Specifically speaking,it independents obstacle avoidance of UAV based on incomplete Artificial Potential Field Method based on Follow-Wall behavior,it realizes the autonomous landing of UAV based on AprilTags precise positioning and incremental adaptive PID control method.Thirdly,this paper designes the PC software.It realizes the human-computer interaction based on presentation layer.It realizes data storage and read based on data access layer.It also achieves the video anomaly detection and UAV mapping based on the business logic layer.In the meantime,the data communication between host computer and lower computer is designed based on Socket TCP/IP.Finally,the inspection system was tested.The design scheme and system function of this paper are tested experimentally by simulating the factory environment.The results verify the feasibility and effectiveness of this system,and the research objectives of the subject are achieved.
