Embodiment 1

[0043] A blockchain-based concealed project quality acceptance method, used to verify the concealed project at each stage; , register an account, and obtain their respective digital certificates and keys. The construction party carries out the construction normally; the supervisory party supervises and records the problems, and uploads them to the blockchain; the quality information of the concealed project collected in real time through sensors, RFID chips, cameras and other IoT devices is uploaded and stored in the form of hash certificates in the blockchain. After the phased construction content is completed, the above-mentioned concealed project quality acceptance method based on blockchain is used for phased acceptance; it should be noted that the concealed project is difficult to conduct secondary inspections after coverage, which is special compared to ordinary projects. The whole process of side station supervision is carried out for the construction of hidden project...

Embodiment 2

[0056] A concealed engineering quality acceptance system based on blockchain, such as image 3 As shown, including: blockchain, construction party client, supervisor client, construction party client and IoT devices;

[0057] Among them, the client of the construction party, the client of the supervisor, the client of the construction party and the IoT devices are all connected to the blockchain;

[0058] After self-checking the quality information form of the concealed project, the client of the construction party initiates a request for quality acceptance of the concealed project to the blockchain; after receiving the quality acceptance request initiated by the client of the construction party, the blockchain forwards it to the client of the supervisor , after being confirmed by the supervisor client, the construction client digitally signs the quality information form and uploads it to the blockchain; form for compliance review;

[0059] When the quality information form ...

Abstract

The invention discloses a hidden project quality acceptance method and system based on a block chain, and the method comprises the steps: enabling a construction side client, a supervisor side client and a construction side client to interact under the action of the block chain, and carrying out the signature verification under a traceable acceptance flow; subjecting the unqualified data of compliance examination or examination of a supervisor client to evidence storage, so that a three-party consensus basis is provided for subsequent quality problem traceability, repair and rework disputes and the like, wherein the electronic archiving reliability is relatively high. According to the invention, the benefit related party in the hidden project participates in the hidden project quality acceptance process through the block chain, so that the hidden project acceptance process is safer; besides, the quality information form is examined in combination with the quality information, collected by the Internet of Things, of the hidden project in the construction process of the hidden project, monitoring and voucher recording of the hidden project which is difficult to be subjected to secondary acceptance are formed, and a manual side station without third-party recording is converted into an electronic side station, so that examination is more transparent.

Description

technical field [0001] The invention belongs to the field of construction project management, and more specifically relates to a block chain-based concealed engineering quality acceptance method and system. Background technique [0002] Concealed works are the previous sub-projects that are covered, wrapped, and shielded by subsequent processes or sub-projects. For example, foundation engineering in housing construction, steel reinforcement engineering in concrete engineering, underground waterproofing engineering, roof waterproofing engineering and other projects must be inspected and accepted, and can only be concealed if they meet the regulations, so as to avoid hidden quality hazards and affect structural safety and use functions. [0003] In the current concealed project acceptance, the three parties involved (construction party, supervisor, and construction party) are independent of each other, and only the project management personnel, supervisors, construction unit c...
