This utility model discloses a luminous label with a self-destructing disassembly structure, comprising a light-emitting sheet assembly, a strong adhesive film layer, and a detachable circuit assembly. The circuit assembly includes an ultra-thin switch module and a Micro LED flexible light-emitting module. The ultra-thin switch module is bonded between the Micro LED flexible light-emitting module and the strong adhesive film layer, and the Micro LED flexible light-emitting module is bonded between the light-emitting sheet assembly and the strong adhesive film layer. One side of the strong adhesive film layer is used to fix it to the side wall of the bottle container, and the other side of the strong adhesive film layer is bonded to the light-emitting sheet assembly and the ultra-thin switch module. The side of the strong adhesive film layer facing the bottle has a reinforcing double-sided adhesive attached next to the recycling handle. This utility model has the function of easily removing the luminous bottle label from the bottle after use, and has automatic damage and waterproof functions. The ultra-thin, easily recyclable luminous bottle label has excellent flexibility and can adapt to the surface of various curved wine bottles. It is beautiful, environmentally friendly, and highly practical.

This invention discloses a method for generating unique identifiers based on RAM tags. The first step involves receiving commands from higher-level software via a command processing module. The second step involves identifying and processing the command type using the command processing module. An initialization module and a control logic module receive and process the commands issued after parsing and identification by the command processing module. These processing operations include creating a unique identifier, destroying the unique identifier, and initializing the RAM. This invention utilizes the characteristics of the RAM to simultaneously achieve serial and parallel searching, processing multiple tags at once and shortening the delay in generating unique identifiers. During processing, a temporary 24-bit counter is divided into two parts: one part indexes the RAM to obtain multiple tag outputs, and the other part indexes these tag outputs in parallel, enabling simultaneous checking of available positions for multiple tag outputs. Furthermore, through accumulator and scrambling processing, the generated identifiers are randomized, avoiding the reuse of recently destroyed identifiers.
