ABSTRACT:
An electronic label data exchange system has work posts adapted for data transmission with objects passing through the posts and with a central control. The objects are provided with electronic labels having a non-volatile memory which may be cleared and written into by the work post devices. The work post fixed transmission devices each have a modulator-demodulator for connection to the control center, a coder-decoder connected to a receiving circuit and to a transmission circuit, and may also include a power transmission circuit for supplying the electronic circuits of the electronic labels with power. Each electronic label has a reception circuit and a transmission circuit in addition to the non-volatile memory. A local data exploitation circuit is connected to the modulator and to the demodulator disposed in each fixed transmission device.
