The Develop Of Real-Time Sensor Parts Size Detection System Based On Machine Vision And Motion Control

With the development of science and technology advancement, modern electronic technology and advanced manufacturing technology, automotive electronics degree higher.The Sensor is one of the important components indispensable in automotive electronic control systems,they are Widely used in the automotive and varied.The requirements of automotive sensor structure size are mainly used to the higher body control system, chassis, engine control systems and other systems, greatly improving the level of automotive electronics, increasing the safety factor driving the car. It is difficult in terms of accuracy for the traditional manual detection method, speed and degree of automation to fully meet the requirements of the sensor to detect parts.Based on Machine Vision machine vision and motion control systems constituted by the motion control is the use of modern PC technology, automation technology and digital image acquisition and processing technology, through CCD search for targets and orderly movement of the motor and other executive agencies, and ultimately to handle the booking of the moving target.It is a modern automated production of key technologies in recent years, is widely used in industrial automation. Based on a combination of both to replace manual inspection will greatly improve the efficiency and quality of the detection process, making the whole production efficiency improvement. Therefore, this combined with practical application, based on real-time target auto size detection sensor parts for machine vision and motion control study to automate part size effective, rapid detection.This paper describes the development of the principles of machine vision and motion control technology and its development status and vision measurement technology at home and abroad and abroad.The main contents of this paper include:(1) describes the selection of motion control systems, the working principle of the servo motor and servo motor.2introduces the PLC as controller of the servo system and PC serial communication methods through the practical application of targeted industrial introduces Panasonic PLC’s MEWTOCOL-COM communication protocols and communications with the host computer.(3) Since each of the parts to be detected at many places, using a template matching can be well positioned to each measurement target ROI, and edge detection.4Finally, the establishment by selecting the camera, light source, such as machine vision systems and lenses, which describes the selection of the appropriate lens size measurements will help to get high quality images to improve the detection accuracy; complete set of automated detection system in accordance with its unique communication protocol; VS2010as a platform to write a stable, efficient and simple system software.With the development of modern industrial automation, on the occasion of applications based on part size detection accuracy, speed, and customer application requirements, combining hardware and software to establish a practical and efficient compliance with the requirements of modern automated machine vision-based automotive sensors and motion control Part real-size detection system has good robustness for subsequent detection of factory automation implementation provides technical guidance.
