Research On The CCD Strip Steel Width Gauge

The strip width online detection technology is of great importance to the steelindustrial, and it has important practical application during the strip’s production process.The use of the linear array CCD device has a series of advantages. It makes the strip widthmeasurement become non-contact, high accuracy, easy to processing, and also easy to beconnected with the automatic control equipment. Therefore, the study of this topic to theonline measurement system of the CCD strip width gauge has great practical significanceand application prospects.The online width measurement of hot rolling strip steel is on the bases of thephotoelectric detection technology. At the same time, this technology is the integration ofthe technology such as electronics, optics and computer science. So the basic principle ofthe CCD image sensor will firstly be studied in this article, and then the CCDphotoelectric conversion principle, the characteristics, working principle and systemstructure of the GCK-IIA type width gauge will be studied combining with the basicmeasurement principle of linear array CCD. Then the driving principle of the hardwaresystem and the data processing will be deeply studied. The study will be continuedthrough making deep research on the hardware circuit composition and the function ofeach part of the CCD photoelectric width gauge. Finally, the site installation andcommissioning operation of CCD strip width gauge will be conducted. And through thisprocess the software operation interface of the CCD width gauge will be understood. Thenthe setting method, the calibration method and the matters needing attention during theoperation will be studied.Through debugging and operation in the industrial field, the measurement principle,the function implementation of the hardware system and software system of the CCD stripsteel width gauge are deepened.
