Garbage classification two-dimensional code generation method based on different combination modes

Abstract

The invention discloses a garbage classification two-dimensional code generation method based on different combination modes, and the method comprises the following steps: extracting an identity display code and a hidden code from a garbage bag identity code, and carrying out the numeric data and binary conversion and integration operation, thereby obtaining an integrated binary sequence B; high-order and low-order combination rule parameters kswitchch1 and kswitchch2 are obtained through calculation by using the chaotic signal, the sequence B is sequentially and positively grouped by taking four elements as a unit, then different modes of combination are respectively performed according to the parameters kswitchch1 and kswitchch2 by taking two grouped sequences as a unit, and the kswitchch1 and kswitchch2 are adjusted in real time along with the updated chaotic signal; wherein the updated chaotic signal is related to the binary combination sequence, so that the garbage classification number is generated, and the garbage classification two-dimensional code is generated through combination. The garbage classification two-dimensional code generation method based on different combination modes is simple and feasible, has very high security and is not easy to crack, and the generated garbage classification code has uniqueness, security and garbage classification guidance.

Description

technical field [0001] The invention belongs to the technical field of garbage classification, and in particular relates to a method for generating a two-dimensional code for garbage classification based on different combinations. Background technique [0002] With the rapid development of the economy and the acceleration of urbanization, the current annual output of urban domestic waste in my country exceeds 100 million tons, accounting for about 20% of the world's total waste output, and it is growing at a rate of 8% to 9% every year. Many cities are facing The grim situation of "garbage siege". At the same time, there are no "burial" places for garbage around many cities, and the landfills in many places have become saturated. Faced with the situation of increasing garbage production and deteriorating environmental conditions, how to maximize the utilization of garbage resources, reduce the amount of garbage disposal, and improve the quality of living environment through ...

AI Technical Summary

Problems solved by technology

In the final analysis, the following reasons can be summed up: First, there is a lack of relevant legal constraints. Compared with the implementation of waste classification in foreign developed countries, there are corresponding laws as support; second, there is a lack of economic incentives and rewards, and a lack of waste classification knowledge and environmental protection awareness. Insufficient and low enthusiasm for participating in activities; thirdly, the infrastructure of garbage recycling stations is too simple, the process of garbage recycling and transportation is too extensive, and residents are negative or even unwilling to participate because of concerns about the exposure of personal privacy information in garbage bags. , the implementation of urban waste classification in my country is facing many difficulties and challenges
