On-line Glass Defect Inspection System Based On ARM/DSP Dual Core And UcLinux

Along with the development of microelectronics and computer technique, the automation and the intelligence of industry production turns the degree higher. In regard to glass industry produce, the method of float glass quantity for examination is all a request to by person's eye off-line examination or appropriation instrument sampling examine, can't satisfy real time examine, and person's eye can discover bigger glass defects, so the glass quantity can't increase. Now several large glass companies in local start adopting importing exam equipments, can realize the glass on-line inspection in 100%, automatically demarcate glass grade, and acquire the quantity covariance data, guide the glass produces, stabilizing the glass quantity level.But because the price is expensive, plus the float method glass production is complicated, needs the very long-playing kit and adaptation, and the accessories replaces are difficult and after-sales services are hard etc. They tied up the local business enterprise to usher in to this kind of equipments seriously, can't increase local business enterprise's competition in international market.Reply this problem, our main research is the possibility according to the on-line embedded inspection system based on DSP and ARM independent multi-core, putting forward the homologous development targets and the function parameter, based on TI company's TMS320C6202B DSP we give out the main project according to the process of video, defect inspections, hardware design and the mold of software;Discussed the industry control by embedded system and networks transfer—usethe ARM-S3C4510B of Samsung company to control, circulating uClinux operate system, Designing the arrangement module of software and data processing flow of the whole embedded system, the rock-bottom of programme software module provides hardware operation and flow for application program, delivering the result of defect inspection. Simultaneity, the paper make a deep discussion to the identify principle of glass defect, and summarize the identify steps like image process, image divide and pick-up character points. This system will be the important thing to improve the production level, intelligent grade of on line glass defect inspection; increase the product quality, production efficiency and automation level, decrease the investment and cost of that.
