SURVEILLANCE SYSTEM FOR A PLURALITY OF CONTAINERS USING ULTRASONIC SEALS

摘要

System for monitoring a plurality of containers using ultrasonic seals integral with the containers and electronic circuits connected to these seals, wherein: (A) each seal comprises an ultrasonic transmitting transducer and an ultrasonic receiving transducer making it possible to check both the identity of the marking and the integrity of the seal, the marking being located outside the seal body, (B) the electronic circuits connected to these seals comprise: (a) at least one cyclic, sequential module for the auscultation or listening to the seals having the same number of outputs and inputs as there are seals, the outputs being connected to the transmitting transducers and the inputs to the receiving transducers, (b) at least one electronic processing module connected to the listening module and controlling a sampling of the signal received.
