| 摘要 |
The invention concerns a method, a system and a component for systematically and automatically controlling a product (1) whereof the preservation in a distribution circuit depends on temperature, in particular a product (1) subjected to a cold chain. The method comprises: a step which consists in affixing on the product (1) a marker (3) comprising elements (4), in particular the bars of a barcode to be identified by automatons (5), a step which consists in fixing on the product (1) a component (6). The component (6) includes at least a part (7) comprising masking means (8) for masking, at least temporarily, without modifying them, said elements (4) of said marker (3) when (i) the temperature of said product (1) exceeds a specific temperature threshold or (ii) when the preservation conditions differ from a specific reference level, in particular characterized by excess of a specific temperature threshold for a longer duration than a specific rime interval or by excess of a specific preservation duration.
