Block chain-based sleeve grouting quality traceability method and system, and collection terminal

Abstract

The present invention discloses a block chain-based sleeve grouting quality traceability method and system, and a collection terminal. The method comprises: step S1: establishing a unified quality traceability standard and a data collection method; step S2: based on a grouting event, collecting associated traceability information in a batch manner through the collection terminal, and forming a data fingerprint of the event to ensure the integrity and non-repudiation of the uplink data; step S3: performing block chain distributed accounting on the sleeve grouting traceability information and the spot check result; and step S4: tracking the sleeve grouting quality based on a unified traceability interface and a security access strategy. The system comprises a traceability standard module 1,a traceability information collection terminal 2, a quality traceability BIM module 3, a traceability information block chain accounting module 4, and a query traceability module 5. According to the method disclosed by the present invention, one of the bottlenecks of the standards, methods, tools, efficiency, safety, supervision and the like for tracking the sleeve grouting quality which restrictthe scale development of the industry in the new building industrialization process can be effectively solved.

Description

technical field [0001] The invention relates to the field of quality traceability of new construction industrialization, in particular to a method, system and collection terminal for socket grouting quality traceability based on blockchain. Background technique [0002] The quality management of sleeve grouting is one of the key links related to the large-scale development of prefabricated buildings. At present, the sleeve grouting process records are mostly paper-based and hand-signed, and the existing electronic data word / excel forms, including on-site photos / videos, are mostly in the form of more than actual effects. It is impossible to effectively record the construction project, grouting location, responsible person, supervision The personnel and the key traceability information of grouting quality are associated, and the grouting event data is scattered and incomplete, easy to tamper, easy to lose, and poor traceability. At this stage, under the background of the lack...

Problems solved by technology

At present, the sleeve grouting process records are mostly paper-based and hand-signed, and the existing electronic data word / excel forms, including on-site photos / videos, are mostly in the form of more than actual effects. It is impossible to effectively record the construction project, grouting location, responsible person, supervision The personnel and the key traceability information of grouting quality are associated, and the grouting event data is scattered and incomplete, easy to tamper, easy to lose, and poor traceability

At this stage, under the background of the lack of effective inspection methods for the quality of sleeve grouting, it is particularly important to establish a quality traceability system for sleeve grouting that involves all parties to promote the healthy and rapid development of new construction industrialization. It is urgent to solve the problem of sleeve grouting. The following problems exist in quality traceability: (1) Lack of quality traceability standards and methods for sleeve grouting; (2) Lack of effective traceability information collection methods and collection equipment; (3) Lack of efficient collection, self-verification, anti-repudiation and prevention of (4) Lack of data trust mechanism among important participants and supervisors of sleeve grouting; (5) Lack of quality traceability of sleeve grouting in construction process and quality traceability of building life cycle
