1. A conveyor system comprising a conveyor adapted to move articles along a certain conveyor path, at least one pass sensor designed to detect an article in motion on the conveyor going past at a certain point of the conveyor path and to respond to a detection of said article going past by delivering a pass detection signal to a monitoring and control unit via a field-bus, which monitoring and control unit responds to the pass detection signal by delivering a control signal for an electromechanical actuator of the conveyor via said field-bus, said conveyor system being characterized in that it further comprises a movement tracking system suitable for generating digital images containing the articles in motion in the conveyor, in that said pass sensor is a virtual sensor represented in a 3D digital model of the conveyor, and in that it includes an emulator configured to transform said images generated by the movement tracking system into 3D-modeled articles and to detect the 3D interactions between the 3D-modeled articles and the virtual sensor represented in the 3D digital model of the conveyor, and on the basis of such detections, to generate said pass detection signals that are delivered to said monitoring and control unit via said field-bus. |
