Abstract

The quest for ever increasing productivity, in a modern manufacturing environment, has spurred the advancement in the application of computer technology at an ever increasing pace. Due, in part, to the desire to have these applications perform in real-time closed loop control environment, many applications dictated the incorporation of dedicated embedded hardwired processors for high data rate applications. Relegating the general computational capabilities of a host processor (typically PC based) to supervisory tasks or low data rate acquisition and analysis tasks. Manufacturer's are fast approaching the natural limits of these traditional architectures (driven more by cost issues than technological barriers) and are seeking alternatives which will increase the scope of applicability of these technologies, as well as provide increasing flexibility in applying their manufacturing resources to a wider array of tasks. In this regard a truly independent, yet tightly coupled, multiprocessing architecture offers the greatest potential for reducing the barriers to high data rate acquisition (digital image processing) based closed loop manufacturing systems. This paper would present one such alternative architecture applied in a Video Feedback Closed Loop (VFCL) manufacturing environment. The author will present the underlying theoretical basis for such systems, in addition to real-world examples of the implementation of several VFCL enabled systems an the benefits achieved through their adoption.
