Research On Main Control System Of Ultrasonic Oil Storage Tank Bottom Corrosion Detection Robot

Oil storage tanks are one of the main storage containers for petroleum and other raw materials.As the oil reserve strategy continues to escalate,a large number of oil storage tanks are in the state of being used,and lack of daily maintenance,resulting in many safety hazards in the oil storage tanks.Corrosion defects of the tank wall can be manually detected outside the tank by many mature detection methods,but the bottom of the tank in service can not be detected by conventional methods,so the bottom detection is the key to determine whether the tank needs to be repaired.To this end,this paper studies the online detection of the bottom of oil storage tank in service.The main control system of the bottom of the oil storage tank corrosion detection robot is to detect the controlling software of human-machine interaction of the upper computer.In this paper,through the research on physical conception,the propagation characteristics and detection principle of ultrasonic,combined with WinForm application development technology,Socket network communication technology and database interaction technology based on Entity Framework,the upper computer is the core control unit of the whole detection system,the C# programming language and multi-threaded programming method are used to design and implement the host computer control system of the ultrasonic oil storage tank bottom corrosion detection robot.Through the network communication between the host computer and the detection robot,the scheduling,parameter setting and data interaction of the robot flaw detection module,the mobile control module and the positioning module of the ultrasonic storage tank bottom corrosion detection by the main control system are realized;Applying wavelet analysis theory,principle of ultrasonic thickness measurement and three-dimensional positioning algorithm respectively process the ultrasonic detection data and the robot positioning data;Building a storage tank for all data information access to detect the upper computer database,and completing information display and result analysis functions of the ultrasonic storage tank bottom corrosion detection robot through the self-designed human-computer interaction interface.This paper completes the function verification of the main control system based on the standard test block through the self-built software test experiment platform.The results showthat the main control system of the ultrasonic storage tank bottom corrosion robot can run smoothly,realizing the information communication inside and outside of the tank,the organic scheduling of the modules in the tank detection robot,the real-time processing of the detection data,the dynamic update of the database and the result display function.
