Concrete quality tracing method based on block chain

Abstract

The invention relates to the field of concrete quality traceability, and particularly discloses a concrete quality traceability method based on a block chain, and the method comprises the steps: a block chain system is constructed, a project is brought into the block chain system through a supervision mechanism, and a certificate is issued to an authenticated node; the concrete production user and the supervision project department input related information into a distributed account book through corresponding nodes; test piece manufacturing information is input into the RFID passive tag; and the detection unit checks the information in the RFID passive tag through the block chain system, and inputs the detection result into the distributed account book. According to the invention, the block chain technology is adopted to solve the ciphertext robbery problem caused by a single network channel and the data tampering problem caused by server centralization and data management centralization, and the block chain technology is combined with the RFID anti-counterfeiting technology, so that the data sharing is realized, the user can be effectively prevented from tampering the data, and the security of the supervision system is greatly improved.

Description

technical field [0001] The invention relates to the field of concrete quality traceability, and specifically discloses a blockchain-based concrete quality traceability method. Background technique [0002] Concrete is the main raw material in construction engineering. With the prosperity and development of the current construction industry, the demand for concrete is increasing year by year. The stability of the concrete structure directly affects the quality of the building. However, there are still problems such as witnesses, samplers not being on site, and maintenance of test blocks (ready-mixed commercial concrete companies directly provide cured test pieces for construction units for inspection) and other problems, resulting in concrete in the test report. The strength value cannot really reflect the concrete strength value actually used in the project. [0003] Moreover, due to the lack of methods to manage the whole process of the inspection work of the inspection ag...

Problems solved by technology

However, there are still problems such as witnesses, samplers not being on site, and maintenance of test blocks (ready-mixed commercial concrete companies directly provide cured test pieces for construction units for inspection) and other problems, resulting in concrete in the test report. The strength value cannot really reflect the concrete strength value actually used in the project

[0003] Moreover, due to the lack of methods to manage the whole process of the inspection work of the inspection agency, the competent department cannot check and supervise the progress of the inspection task and the situation that occurs during the inspection process in real time, check the number of inspections and supervise the progress of the inspection task and the occurrence of problems during the inspection process. The situation, the test data and test report are not uploaded to the supervision platform in real time, it is difficult to distinguish the authenticity of the uploaded data, which is not conducive to the effective supervision of the supervision department

[0004] In addition, the current centralized data sharing, reading, verification, and traceability still have problems such as untimely and difficult balance; in terms of authority, data management in the concrete quality inspection and traceability system depends on the supervision of relevant departments, data entry or relevant Personnel can selectively hide or even tamper with basic data that is not good for their own interests
