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

[0092] According to the above-mentioned two-dimensional code generation method for Chinese character garbage classification, the steps are as follows:

[0093] (1) transcoding

[0094] First, encode the identity information of a certain garbage bag to generate a unique Chinese and English character garbage bag identity code, which is "Jiangsu Province-Nantong City-Haimen District Zhongnan Century City-12#1201 Li Xiaoqiang 15005709999 2020-08-01 01", The length is k+L+p+n+6=11+13+14+10+6=54, where "Jiangsu Province-Nantong City-Chongchuan District" is the province and city, "Zhongnan Century City-12#1201" "Li Xiaoqiang 15005709999" is the contact person and telephone number, "2020-08-01" is the year, month, and day when the code was made, and "01" is the color information of garbage classification (such as green recyclable Rubbish);

[0095] Then, extract the identity display code (Jiangsu Province-Nantong City-Haimen District 2020-08-01 01) and the identity concealment code ...

Embodiment 2

[0120] According to the above-mentioned two-dimensional code generation method for garbage classification with Chinese characters, the generation steps of the identity hidden code, external key and two-dimensional code for garbage classification with Chinese characters of a certain garbage bag are similar to the specific embodiment 1, and only the identity of a certain garbage bag is displayed Minor changes in the provinces, municipalities, or the year, month, and day of code production: "Gongsu Province-Nantong City-Haimen District 2020-08-01 01"; or "Jiangsu Province-Nantong City-Haimen District 2020-08-01 01"; or "Jiangsu Province-Nantong City-Haimen District 2020-08-11 01", the generation results of the Chinese character garbage classification (two-dimensional) code are shown in Table 1. It can be seen from the following table: slight changes in the identity display code (province, city or code-making year, month, day) in the garbage bag ID code will cause a large change in...

Embodiment 3

[0126] According to the above-mentioned two-dimensional code generation method of a kind of Chinese character garbage classification, the identity hidden code, external key and Chinese character garbage classification two-dimensional code generation steps of a certain garbage bag are similar to the specific embodiments 1 and 2, for the garbage bag identity code ( "Jiangsu Province-Nantong City-Haimen District Zhongnan Century City-12#1201 Li Xiaoqiang 15005709999 2020-08-01 01', or "Gongsu Province-Nantong City-Haimen District Zhongnan Century City-12#1201 Li Xiaoqiang 15005709999 2020-08- 01 01", or "Jiangsu Province-Nantong City-Haimen District Zhongnan Century City-12#1201 Li Xiaoqiang 15005709999 2020-08-01 01', or "Jiangsu Province-Nantong City-Haimen District Zhongnan Century City-12#1201 Li Xiaoqiang 15005709999 2020-08-11 01"), only the garbage classification color information ("01") in the original garbage bag identity information has changed slightly: "02"; or "03"; o...

Abstract

The invention discloses a method for generating a two-dimensional code for garbage classification in Chinese characters, which comprises the following steps: extracting an identity display code and a hidden code from a garbage bag identity code and performing data conversion and combination operations respectively to obtain a combined binary matrix B and high, Low-order combined binary sequences B1 and B2; calculate the initial value and parameters of the chaotic system, the extraction start position, and the number of extraction intervals, and use the position change rules of the chaotic sequences Y and Z obtained by chaotic iterations before and after descending sorting. Binary sequence B1 , B2 are respectively scrambled; the scrambled binary sequence is grouped in the forward direction in units of 6 elements, and then the grouped sequence is diffused to generate a garbage classification number, and then combined to generate a Chinese character garbage classification QR code. The method for generating the two-dimensional code for sorting Chinese characters for garbage is simple and feasible, has strong security and is not easy to crack, and the generated garbage sorting code has "uniqueness, security and guidance for garbage sorting".

Description

technical field [0001] The invention relates to the technical field of garbage classification, in particular to a method for generating a two-dimensional code for garbage classification in Chinese characters. 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",...
