Patent ID: 6849860

Claim:
A detection system for the detection and tracking of optical codes ( 45 , 47 ) on objects ( 41 , 43 ) which are transported along a monitored zone, comprising a plurality of optoelectronic sensors ( 11 , 13 , 15 ) to read the codes and to generate corresponding reading data; further comprising at least two data buses ( 21 , 23 ) each having its own associated bus control unit ( 17 , 19 ); and comprising at least one system interface ( 35 , 37 ) to output output data to a higher level system control unit ( 33 ), wherein each of the plurality of sensors ( 11 , 13 , 15 ) is connected both to the one ( 21 ) and to the other ( 23 ) of the two data buses; and wherein the one ( 21 ) of the two data buses with the associated bus control unit ( 17 ), on the one hand, and the other data bus ( 23 ) with the associated bus control unit ( 19 ), on the other hand, are divided into a primary branch and a secondary branch which is subordinate to the primary branch.
