| As an emerging composite pipeline,steel-plastic composite pipeline,because of its requirements for high-precision technology and the complexity of the production process,in its manufacturing process,the failure to obtain pipeline production data in time will cause the waste of pipeline raw materials and increase the production of manpower operations,which will produce unnecessary economic losses.The automatic online monitoring system of steel-plastic composite pipe studied in this paper can monitor the real-time quality information of steel-plastic pipe production,and monitor the position of the stencil,wall thickness,ovality and other information in real time,which is an efficient solution to obtain production data in time.Therefore,the development and research of online automatic inspection system for steel-plastic composite pipes can bring economic benefits and reflect the value of engineering applications.This paper conducts research on pipeline inspection and image processing related detection systems,first of all,the current research and analysis of pipeline inspection and image processing at home and abroad,and then the system demand analysis and overall scheme design,and then according to the overall needs of the monitoring system,the hardware is divided into four modules,core control module,ultrasonic testing module,mechanical control module and water circulation module,respectively,design and build four modules of online monitoring system,from the hardware design to meet the basic requirements of ultrasonic monitoring system.According to the detection requirements of the system,the mechanical control strategy of ultrasonic testing is designed.Then,from software,the online monitoring system is analyzed into two levels,namely the main functional module and the auxiliary function module.Then,based on Visual Studio design system software processing interface and algorithm,the software part is based on C++combined with OpenCV by image processing of the obtained ultrasonic detection data,and proposes the SURF algorithm to collect and match feature points according to the situation of pipeline vibration to improve the accuracy of detection.Finally,the experimental test is carried out on the continuity,functionality and accuracy of the operation of the system,and the test data is studied and analyzed to verify the capabilities of the system,and the test results show that the modules of the monitoring system designed in this paper operate well and communicate well,and the ability to detect data meets the standards of engineering technology application. |
