Gas cylinder quality and safety traceability system and control method based on ocr and blockchain

Abstract

The invention discloses a gas cylinder quality and safety traceability system and control method based on OCR and block chain, which includes a data collection layer, a gas cylinder traceability layer and a block chain platform layer; a data collection layer, gas cylinder related business participants Upload the read-out gas cylinder manufacturing information, filling information, inspection information and circulation traceability information to the gas cylinder traceability layer; the gas cylinder traceability layer receives the information code from the data acquisition layer, The data in the process of equipment registration, regular inspection, and circulation traceability are entered into the blockchain platform for storage. The invention provides a gas cylinder quality and safety traceability system and control method based on OCR and blockchain, which reads the stamp number through OCR technology, replaces the reading of the existing information-based identification, and prevents it from being copied, disassembled, and replaced; application area Blockchain technology ensures that decentralized applications and data cannot be tampered with; smart contracts are used to define regulatory rules to prevent gas cylinder companies from making fraud.

Description

technical field [0001] The invention relates to a gas cylinder quality and safety traceability system and control method based on OCR and blockchain, and belongs to the technical field of gas cylinder safety supervision. Background technique [0002] At present, in the field of safety supervision, gas cylinders are special equipment related to people's livelihood and safety, and their quality and safety have very important economic and social benefits. In the process of informatization supervision, the informatization identification (one-dimensional code, two-dimensional code, electronic label, etc.) fixed on the gas cylinder is easy to be copied or replaced, and the good informatization identification is dismantled and installed to the actual problem On the gas cylinder, sweep A and charge B, and fill it with a second one. At the same time, gas cylinder companies generally use self-built and third-party platforms. This type of system uses a centralized storage model. In th...

Problems solved by technology

At the same time, gas cylinder companies generally use self-built and third-party platforms. This type of system uses a centralized storage model. In this model, since the company and the third-party platform are both stakeholders, once information exists, it is not conducive to In their own situation, these enterprises will falsely register, tamper with data or even deny, etc., causing difficulties in proving evidence and pursuing accountability, and bringing great hidden dangers to safety supervision
