Sensing and guiding techniques for rubber

Abstract

A description is presented of the Elcom 18 (electronic control and communication) System used in conjunction with a CCD line scan camera. Elcom uses a 19-in rack system for plug-in printed circuit boards. The system includes a special digital/analog bus that processes both analog and digital signals. The software for Elcom is divided into two categories: the system software and the application software. The system software processes the camera signals and organizes and directs the internal operation. The application software defines the function of the control system and is stored in a small plug-in circuit board containing an EPROM. Elcom 18 is capable of interactive communication. It can be connected via digital input and output boards or serial interface with keyboards and terminals, as well as other computer systems and PLCs. The data source for Elcom can be virtually any analog or digital signal. The source most frequently used is the CCD line scan camera.<>
