Supply chain management and control method for prefabricated building components

Abstract

The invention discloses a supply chain management and control method for prefabricated building components, and the method comprises the steps: building a component block chain management platform, and inputting the number of each component; receiving a supply chain query request of a node, and verifying the identity of a visitor by using an asymmetric encryption algorithm in a network layer; if the decryption is correct by using the public key, querying and obtaining basic specification information of the component stored in the target block; reading related data of the current block by utilizing an intelligent contract stored on a block chain; enabling the server to obtain a conclusion, encrypt the information by using the corresponding private key, and return the information to the query end, and enabling the query end to decrypt the information by using the corresponding public key to obtain the information; and receiving evaluation information of each node on the supply chain, andstoring the evaluation information in the block chain. The method effectively ensures that the information in the building component supply chain is real and cannot be tampered; query and time tracking are more convenient; the responsibility definition is more accurate, and the management efficiency of the fabricated building component supply chain is improved.

Description

technical field [0001] The invention belongs to the field of building industrialization, and in particular relates to a supply chain management and control method for assembled building components. Background technique [0002] Nowadays, prefabricated components are mostly used in building construction. Typical prefabricated components such as prefabricated walls, prefabricated panels, prefabricated beams, prefabricated stairs, etc., also have prefabricated partial units, such as balconies, rooms and so on. [0003] The supply chain of a formed prefabricated component needs to go through multiple links, including raw material purchase, manufacturer processing, and the participation of transportation companies in the transportation and handover of various nodes, and finally arrives at the construction unit for assembly and construction. [0004] When purchasing raw materials, you will need raw materials such as sand, gravel, cement, concrete, and steel bars. If you want to pu...

AI Technical Summary

Problems solved by technology

[0008] The processing, transportation, and operation of the same building component between multiple manufacturers not only has the problem of trust in the transaction between the upper and lower suppliers, but also the information of the building component in the supply chain cannot be guaranteed to be true and correct. In many links, someone may tamper with the component information. Making ill-gotten gains, and the responsibility for the problem cannot be effectively traced, which affects the efficiency of the entire supply chain management

[0009] All parties in the supply chain, because there is only a handover component relationship, it is not easy to know the supply status of each other's products, lack of mutual trust relationship, and cannot guarantee the real information and responsibility definition of components
