Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart illustrating a method for managing building information according to an embodiment of the present invention, where the embodiment is applicable to a case where prefabricated building information is managed, and the method can be executed by a device for managing building information. As shown in fig. 1, the method specifically includes the following steps:
and step 110, acquiring building information of a participant to which the participant node belongs according to a preset data encryption period.
A data encryption period is preset, and the data encryption period is the interval time between two data encryption operations. And acquiring the building information of the participating nodes once every data encryption period. The participating node is a block chain link point of a participating party in the building assembly process, and for example, the participating node may be a node in a federation chain, the federation chain is a block chain composed of different participating parties, each participating party on the chain is a node, and each node uploads its own information to the federation chain, so that the node cannot be tampered. Participating nodes may include owner nodes, design nodes, supplier nodes, shipping nodes, assembly nodes, and other nodes, among others. The building information of the participant to which the participant node belongs may be basic information and building element information of the participant, the basic information may be names and projects of the participants, and the building element information may be information of the number and state of the building elements. For example, the building information of the owner node may include information of a prefabricated building project, a target of the project, a management concept and content of the project, and the like; the building information of the design node can comprise an initial design file, a construction drawing, design change and the like; the building information of the supplier node may include prefabricated part information, supply and demand amount, unit price, and the like; the building information of the transportation node can comprise transportation vehicle information, transportation cargo information, transportation real-time location and the like; the building information of the assembly node may include assembly member information, assembly position, assembly progress, and the like; the building information of the other nodes may include maintenance information, quality inspection information, energy saving detection information, and the like. Each participant can create and confirm own participant node on the alliance chain, obtain a public key and a private key which are used as identity identifiers, and the participant node can broadcast own building information and the public key to the whole network, obtain and store the building information and the public key of other participant nodes, so that the participant node participates in a sharing management system of the assembled building information, and realizes the management of the building information. The participants may update their own building information in real time, for example, the participants may update the status of the building components from in-transit to end-of-transit. When the time reaches the preset data encryption cycle time, the participating nodes can automatically acquire the self building information, so that manual operation is reduced, and information omission is avoided.
And 120, encrypting the building information according to a preset data encryption algorithm to obtain building encryption data.
A Data Encryption Algorithm may be preset, and the Data Encryption Algorithm is used for encrypting the building information, for example, the Data Encryption Algorithm may be MD5(Message-Digest Algorithm 5) or DES (Data Encryption Standard) Algorithm, and the like. After the self building information is obtained, the building information can be encrypted by using a data encryption algorithm to obtain building encryption data, so that the building information is prevented from being leaked.
In this embodiment, optionally, the encrypting the building information according to a preset data encryption algorithm to obtain building encrypted data includes: performing first hash calculation on the building information according to a hash algorithm to obtain an initial hash value of the building information; and performing hash iteration on the initial hash value according to a preset encryption requirement to obtain the building encrypted data.
Specifically, the hash algorithm may be used to perform hash calculation on the building information to obtain a hash value of the building information, and the hash value obtained after the first hash calculation is used as the initial hash value. Because the data volume of the fabricated building information is large, in order to save space, the initial hash value can be repeatedly hashed and iterated, so that the requirement of the block on data storage is met, and the confidentiality of the data is enhanced. For example, the building information is encrypted into a 16-bit character string, and then the 16-bit character string is iterated for a plurality of times to generate an 8-bit character string as building encryption data. The hash iteration is to take the hash value obtained in the previous time as a value to be processed, and perform hash calculation on the value to be processed, namely, complete one iteration. The beneficial effects of the arrangement are that the method is beneficial to managing a large amount of building information, meets the block storage requirement, avoids the building information from being leaked or tampered by hashing for multiple times, and improves the reliability and accuracy of data.
The authorized nodes are the participating nodes trusted by the participating nodes, and can be used for storing data of the participating nodes in the building assembly process into the block. After the building encrypted data are obtained by each participating node, the building encrypted data can be transmitted in the whole network through a set transmission protocol, before the building encrypted data are transmitted by the participating nodes, the building encrypted data can be encrypted again according to a private key of the participating nodes, other participating nodes can decrypt the building encrypted data according to a public key of the participating node which sends the data, and the identity of the participating node which sends the data is verified. The identity of the participants and the authenticity of data can be further ensured by verifying all the participating nodes, so that each participating node in the alliance chain participates in each link of block creation and information sharing, and shares the responsibility of verifying data and propagating data blocks.
In this embodiment, optionally, before sending the building encrypted data to the authorization node and storing the building encrypted data in the first block by the authorization node, the method further includes: and determining at least one authorized node from all the participating nodes according to the consensus mechanism of the block chain.
Specifically, the authorized nodes can be obtained by voting of all the participating nodes, a reliable consensus mechanism can be provided for each participating node in the alliance chain according to a consensus algorithm, and the problem of trust communication among the nodes is solved. And (4) voting to select a trusted authorization node by each participating node in the alliance chain according to the share authorization certification mechanism. The number of the authorized nodes can be multiple, for example, two authorized nodes, namely a node one and a node two, are determined, and if the node one uploads the building encrypted data of the node one, the node two can store the block of the node one data, so that the data of each participating node is stored by other participating nodes, the data is prevented from being tampered by the node as the authorized node, and the authenticity of the data is improved. The authorization node needs to be responsible for all the participating nodes, if all the participating nodes find that the authorization node does not generate a new block in time or upload false data with errors, the authorization node loses trust, and all the participating nodes can move the authorization node out of the alliance chain. The method has the advantages that the data exchange of all the participating nodes is realized by determining the authorized nodes, the conflict among the participating nodes is avoided in the data transmission process, the trust problem among the nodes is solved, and the efficiency and the precision of information management are improved.
And step 140, determining whether the building information meets the execution condition of the intelligent contract according to a preset contract execution period.
The intelligent contract is preset in the block chain and is determined by negotiation of each participant. And presetting a contract execution period, acquiring the building information in the participating node every other contract execution period, and determining whether the current building information meets the execution condition of the intelligent contract. For example, the intelligent contract signed by the transportation node and the assembly node is about, and when the transportation state is the transportation end, the assembly operation is started. And when the contract execution period is reached, the transportation node acquires the self building information and determines whether to inform the assembly node to start assembly or not according to the transportation state of the current building component.
In this embodiment, optionally, before determining whether the building information satisfies the execution condition of the intelligent contract according to a preset contract execution period, the method further includes: and sending the confirmed intelligent contracts to the authorization node, and packaging and storing the intelligent contracts into the blocks by the authorization node.
Specifically, the participating nodes confirm an intelligent contract with each other, jointly make a scheme plan and a contract of each interest-related party, and the contract defines the authority and the obligation of the participating parties and is generated after each participating node signs through a private key. The participating nodes broadcast the intelligent contracts which are respectively approved by the signatures to the whole network, and the intelligent contracts are packaged and transmitted into the blocks by the authorized nodes. When the intelligent contract is executed, the intelligent contract only needs to be acquired from the block. The intelligent contract block storage method has the advantages that each participating node makes an intelligent contract and the authorized nodes perform block storage, so that disputes caused by the intelligent contract can be avoided, contract execution efficiency is improved, and building information management efficiency is improved.
In this embodiment, optionally, determining whether the building information meets the execution condition of the intelligent contract according to a preset contract execution period includes: acquiring self-uploaded building information according to a preset contract execution period; and comparing the building information with the execution condition of the intelligent contract to determine whether the building information meets the execution condition of the intelligent contract.
Specifically, a contract execution period is preset, automatic execution of the intelligent contract can be achieved, and when the contract execution period is reached, the participating nodes acquire building information uploaded by the participating nodes and compare the building information with execution conditions of the intelligent contract. If the building information meets the intelligent contract conditions, contract operation can be carried out; and if the building information does not meet the intelligent contract condition, continuing to wait for the comparison of the execution conditions when the next contract execution period is reached. The beneficial effect who sets up like this lies in, can realize the automatic execution of intelligent contract, and need not all the time carry out the comparison of information and condition, alleviates node burden, avoids frequently leading to the data confusion among the data operation, reduces the manual operation, improves the efficiency of contract execution and the efficiency of information management.
And 150, if the first block and the second block are met, executing the intelligent contract, sending the execution result to the authorization node, and storing the execution result into the second block by the authorization node to obtain a building information management chain consisting of the first block and the second block.
And if the building information of the participating nodes is determined to meet the intelligent contract conditions, executing the intelligent contract. In the process of executing the intelligent contract, the completion state of the task in the contract is recorded at any moment by each participating node related to the intelligent contract. After the corresponding task in the contract is completed, the participating node sends specific information of the task completion condition to the authorization node, namely, the execution result is sent to the authorization node, the authorization node packages the execution result and stores the execution result in a second block, the second block is used for storing the completion condition of the participating node on the intelligent contract, and one second block can be created every time the intelligent contract is executed. The first block and the second block can form an information chain of the building component in the whole management process, namely the building information management chain is obtained, and each participating node can manage the building information through the building information management chain, so that the information management efficiency is improved.
According to the technical scheme, building information of the participating nodes is obtained at regular time, the building information is encrypted according to a preset encryption algorithm to obtain building encrypted data, the building encrypted data are stored in a alliance chain by an authorization node, if a plurality of participating nodes cooperate, whether executing conditions are met among the participating nodes is determined according to an intelligent contract, if the executing conditions are met, a contract executing result is stored in the alliance chain by the authorization node, and management and storage of the building information in the whole building process are achieved. The problem of among the prior art, carry out building information management by the manual work is solved, manpower and time are practiced thrift, avoid building information to be tampered at will, are favorable to tracing back building information, have guaranteed the accuracy of information through data encryption and authorized node, realize the automatic processing to the contract through intelligent contract, have improved building information's management efficiency.
Example two
Fig. 2 is a flowchart illustrating a method for managing building information according to a second embodiment of the present invention, which is further optimized based on the second embodiment. As shown in fig. 2, the method specifically includes the following steps:
and step 210, acquiring building information of a participant to which the participant node belongs according to a preset data encryption period.
And step 220, encrypting the building information according to a preset data encryption algorithm to obtain building encryption data.
And 240, determining whether the building information meets the execution condition of the intelligent contract according to a preset contract execution period.
And 250, if the first block and the second block are met, executing the intelligent contract, sending an execution result to the authorization node, and storing the execution result into the second block by the authorization node to obtain a building information management chain consisting of the first block and the second block.
And step 260, the participating nodes sign the content to be acquired by adopting own private keys to obtain the request information.
The participating nodes can obtain their own public keys and private keys when establishing identities in the federation chain, and after determining the building information management chain, the participating nodes can inquire the building information of other participating nodes in the building information management chain. The building information of other participating nodes requested to be acquired by the participating nodes is the content to be acquired, and the participating nodes sign the content to be acquired by using the private keys of the participating nodes to obtain the encrypted content to be acquired, namely the request information.
And 270, sending the request information to the target node, decrypting the request information by the target node by using the public key of the participating node to obtain the content to be obtained, signing the target content corresponding to the content to be obtained by using the private key of the target node, and sending the signed target content to the participating node.
The participating node determines a target node, the target node is a node containing the content to be acquired, and the participating node sends the encrypted content to be acquired, namely the request information to the target node. After receiving the request message, the target node may verify the request message. Because the public key of each node is public information, the target node can decrypt the request information by using the public key of the participating node, if the decryption is successful, the identity of the participating node is determined to be correct, the target node sends target content to the participating node, the target content is specific information corresponding to the content to be acquired, for example, the content to be acquired is a transportation condition of a building component requested to be acquired, and the target content is a specific transportation condition of the building component. The target node can also adopt a private key of the target node to sign the transmitted target content, and the participating node decrypts the target content by adopting a public key of the target node after receiving the target content transmitted by the target node to obtain the specific information of the content to be acquired. The data transmission between the participating nodes and the target node can be broadcasted to the whole network, other participating nodes can know that the participating nodes send requests to the target node and can also know that the target node sends information of contents to be acquired to the participating nodes, so that the participating nodes and the target node are supervised, and the information transmission is public and transparent.
In this embodiment, optionally, after executing the intelligent contract, sending the execution result to the authorization node, and storing the execution result in the second block by the authorization node to obtain the building information management chain composed of the first block and the second block, the method further includes: the participating nodes adopt self private keys to sign the node modification requests; and sending the signed node modification request to other participating nodes except the participating node, verifying the signed node modification request by the other participating nodes through the public key of the participating node, and determining whether to modify the node according to the node modification request according to the verification result.
Specifically, the participating node may not only request other participating nodes to obtain the building information, but also modify the number of other participating nodes except itself, for example, add other participating nodes or delete other participating nodes. The participating node may send a node modification request to all other participating nodes, sign the node modification request with its own public key, and the node modification request may include a name of the node to be modified and a modification reason.
