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

Embodiment 1

[0128] According to the above-mentioned batch generation method of two-dimensional codes for garbage classification, the steps are as follows:

[0129] (1) Encoding and transcoding

[0130] Encode the identity information of a batch of garbage bags, including the unified identity code of a batch of garbage bags and the batch ID code of a single garbage bag, and generate the unique Chinese and English character garbage bag ID of a batch of single garbage bags as "Jiangsu Province-Nantong City-Haimen District Zhongnan Century City-12#1201 Li Xiaoqiang 15005709999 2020-08-02 01 03", the length is k+L+p+n+9=11+13+14+10+9=57 , where "Jiangsu Province-Nantong City-Chongchuan District" is the province, city, "Zhongnan Century City-12#1201" is the specific residential address (such as the community-house number), "Li Xiaoqiang 15005709999" is the contact person and telephone number, " 2020-08-02" is the coding time, "01" is the color information of garbage classification (such as gre...

Embodiment 2

[0168] According to the above-mentioned batch generation method of two-dimensional codes for garbage classification, the steps of generating two-dimensional codes for garbage classification of a certain batch of single garbage bags and the information of external keys, code making dates, garbage categories, and garbage classification serial numbers are similar to those in Embodiment 1. For the garbage bag identification code ("Jiangsu Province-Nantong City-Haimen District 2020-08-", or "Gongsu Province-Nantong City-Haimen District 2020-08-", or "Jiangsu Province-Nantong City-Haimen District 2020-08-", or "Jiangsu Province-Nantong City-Haimen District 2020-09-"), only the identity hidden code in the original garbage bag identity information ("Zhongnan Century City-12#1201 Li Xiaoqiang 15005709999") has changed slightly : "Zhongnan Century City-12#1201 Li Xiaoqiang 15005709999"; or "Zhongnan Century City-12#1211 Li Xiaoqiang 1500570999"; or "Zhongnan Century City-12#1201 Li Xiaoq...

Embodiment 3

[0175] According to the above-mentioned batch generation method of two-dimensional codes for garbage classification, the steps for generating two-dimensional codes for garbage classification of a certain batch of single garbage bags, as well as the hidden codes for the identity of the garbage bags, the date of making the codes, the category of garbage, and the information on the serial number of garbage classification and specific embodiment 1 Similarly, for the garbage bag identification code ("Jiangsu Province-Nantong City-Haimen District 2020-08-", or "Gongsu Province-Nantong City-Haimen District 2020-08-", or "Jiangsu Province-Nantong City-Haimen District 2020-08-", Our District 2020-08-", or "Jiangsu Province-Nantong City-Haimen District 2020-09-"), only the external key (α=0.12345, β=3.75) has a single slight change: α=0.123450000000001; or β= 3.7500000000000001, the generation results of the QR code for garbage classification of a batch of single garbage bags are shown i...

Abstract

The invention discloses a batch generation method of two-dimensional codes for garbage classification, comprising the following steps: extracting identity codes and hidden codes from a certain batch of identity information of garbage bags, and performing conversion and combination operations respectively to obtain a combined binary matrix B, and Binary sequences B1 and B2 combined with high and low bits; relying on identity codes and hidden codes and using chaotic mapping to generate chaotic signal sequences, respectively scrambling, grouping and diffusing high and low binary sequences B1 and B2 to complete a certain batch of garbage bags Unified encryption of identity hiding codes; relying on batch identity codes of single garbage bags and using chaotic mapping to generate chaotic signal sequences, and scrambling the results of unified encryption of identity hiding codes according to garbage categories with different rules to generate garbage classification in batches code. The batch generation method of two-dimensional codes for garbage classification proposed by the present invention is simple and feasible, and has strong security, and the generated garbage classification codes have "uniqueness, safety, and guidance for garbage classification".

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...
