Problems solved by technology

[0007] 4. The number of IPv4 addresses is limited
[0010] 1. Limited data capacity
[0011] 2. The content of the collected information is single
However, how to find hardware devices such as sensors with independent property rights is one of the key factors restricting the development of China's Internet of Things
Nowadays, because two-dimensional barcode technology is widely used in many fields such as industry, commerce, logistics industry, financial industry, government, school, hospital, electric power, telecommunications, transportation, etc., all kinds of two-dimensional barcodes with various codes also have a mature one. However, due to the limited coding information capacity of the two-dimensional barcode, it cannot store large-capacity information

Embodiment 1

[0031] Embodiment 1: Generate a two-dimensional barcode. The index value of this barcode is generated by the title of the famous bestseller "How Steel Was Tempered", and there is no information corresponding to this index on the server. This two-dimensional barcode can be printed on the back of the book. Collect the index of this barcode through the two-dimensional barcode collector, and then you can see it in the data display module:

[0032] "How Steel Was Tempered" is a novel written by the Soviet writer Nikolai Ostrovsky, written in 1933. The novel tells people through the growth path of Paul Korchagin , a person can only create miracles and grow into a steel warrior only when he defeats the enemy and himself in the hardships and hardships of the revolution, and only when he links his pursuit with the interests of the motherland and the people. The struggle to become steel is an important theme of the novel. In 1942, the Soviet Union made a film of the same name based on ...

Embodiment 2

[0034] Embodiment 2: Generate a two-dimensional barcode. The index value of this barcode is a special index specified in advance. For example, for a famous coat, there is record information about this clothing in the server information temporary storage area. The two-dimensional barcode can be printed on the trademark of the clothing, and the index of this barcode can be collected through the two-dimensional barcode collector, and then can be seen in the data display module:

[0035] "Style: Women's Burberry Material: Wool Type: Coat Wash: Washable Waist..."

[0036] And how many scoops of washing powder is used by the current brand, washing time and other information.

Abstract

The invention discloses an Internet of things-based two-dimensional barcode information acquisition identification system, belongs to the fields of two-dimensional barcodes and Internet of things, and aims to solve the problem that the conventional two-dimensional barcodes have limited information capacity and single information format. Due to the application of the Internet of things, the specified encoding information of the two-dimensional barcodes is expanded, and a real-time acquisition identification system for video, pictures, audio and other corresponding digital information is obtained.

Description

technical field [0001] The invention is applied to the fields of information security, information digitization and Internet of Things. Background technique [0002] The Internet of Things (The Internet of Things) uses radio frequency identification (RFID) devices, infrared sensors, global positioning systems, laser scanners and other information sensing equipment to connect any item to the Internet according to the agreed protocol for information exchange and Communication, to achieve intelligent identification, positioning, tracking, monitoring and management of a network. [0003] At present, the development of Internet of Things technology has encountered the following problems: [0004] 1. The breakthrough of RFID technology [0005] 2. Support of sensor technology [0006] 3. Application of cloud computing technology [0007] 4. The number of IPv4 addresses is limited [0008] Two-Dimensional Barcode (Two-Dimensonal BarCode) records data symbol information with a ...
