Garbage classification two-dimensional code batch generation method

Abstract

The invention discloses a garbage classification two-dimensional code batch generation method, which comprises the following steps: extracting an identity identification code and a hidden code from acertain batch of garbage bag identity information, and respectively performing conversion and combination operation to obtain a combined binary matrix B, a high-order combined binary sequence B1 and alow-order combined binary sequence B2; generating a chaotic signal sequence by depending on the identity identification code and the hidden code and utilizing chaotic mapping, scrambling, grouping and diffusing the high-order binary sequence B1 and the low-order binary sequence B2 respectively, and completing unified encryption of the identity hidden codes of a certain batch of garbage bags; generating a chaotic signal sequence by depending on batch identity codes of a single garbage bag and utilizing chaotic mapping, and performing scrambling of different rules on identity hiding code unified encryption results according to garbage categories to generate garbage classification two-dimensional codes in batches. The garbage classification two-dimensional code batch generation method provided by the invention is simple and feasible and has very high safety, and the generated garbage classification code has uniqueness, safety and garbage classification guidance.

Description

technical field [0001] The invention relates to the technical field of garbage classification, in particular to a batch generation method of two-dimensional codes for garbage classification. Background technique [0002] With the rapid development of science and technology, economy and society, and the further advancement of urbanization, the current annual output of domestic waste in my country has exceeded 100 million tons, and many cities are facing the severe situation of "garbage siege". "Garbage besieged city" has become a stumbling block to the development of Chinese cities. To solve the problem of "garbage siege", first of all, reduce the generation of urban domestic waste from the source, and secondly, the recycling of waste is also an indispensable key link, so the implementation of waste classification is imminent. As early as 1992, Yichang City of my country proposed for the first time the implementation of "garbage bagging and classification", and for the first...

Problems solved by technology

In addition, the infrastructure of garbage collection stations is too simple, the process of garbage recycling and transportation is too extensive, and residents are negative or even unwilling to participate in concerns about the exposure of personal privacy information in garbage bags. Obviously, the implementation of urban garbage classification in my country is on the way. facing many difficulties and challenges
