Gas cylinder quality safety tracing system based on OCR and block chain and control method

Abstract

The invention discloses a gas cylinder quality safety tracing system based on OCR and a block chain and a control method. The gas cylinder quality safety tracing system comprises a data acquisition layer, a gas cylinder tracing layer and a block chain platform layer. The data acquisition layer is used for uploading identified and read gas cylinder production and manufacturing information, filling information, inspection information and circulation tracing information to a gas cylinder tracing layer by a gas cylinder related business participant; and the gas cylinder tracing layer is used for receiving information codes from the data acquisition layer, and inputting the data of the production and manufacturing, filling registration, regular inspection and circulation tracing processes of gas cylinders into a block chain platform for storage. According to the gas cylinder quality safety tracing system based on the OCR and the block chain and the control method, the steel seal number is read through the OCR technology, existing informatization identification reading is replaced, and copying, disassembling and replacing are prevented; a block chain technology is applied to ensure that decentralized application and data cannot be tampered; and an intelligent contract is applied to define supervision rules to prevent gas cylinder enterprises from counterfeiting.

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 disassembled 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 ...

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
