Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention. The step numbers in the following embodiments are provided only for convenience of illustration, the order between the steps is not limited at all, and the execution order of each step in the embodiments can be adapted according to the understanding of those skilled in the art.
The embodiment of the invention provides an assembly type building construction quality tracing method based on a block chain, which is used for effectively recording and tracing quality responsibility problems before, during and after the assembly type building construction, and accounting related information and responsibility events by using the block chain technology, so that the event tracing information storage decentralization and non-tampering of key nodes and participants are realized, and a good trust mechanism is established.
Referring to fig. 1, in an embodiment of the present invention, a block chain-based fabricated building construction quality tracing method is provided, including the following steps:
s1: acquiring component supply information of the assembly type building and design information of the assembly type building, and generating a first bill;
s2: generating a second bill according to node information of each preset quality tracking node in the construction process of the fabricated building;
s3: acquiring acceptance record information of a supervisor in the building construction process, and generating a third bill;
s4: establishing an assembled building construction project alliance chain of tracing information interconnection and intercommunication;
s5: performing distributed billing on the first bill, the second bill and the third bill;
s6: and according to the distributed accounting result, the construction quality problem of the fabricated building is supervised and tracked through the unified tracing interface.
Further, as a preferred embodiment, the component supply information of the prefabricated building specifically includes factory supply information and transportation supply information of the components.
A lot of preparation work is required before the assembly type building actually starts to be constructed. In the embodiment of the invention, the tracing target at the stage is mainly divided into two types, wherein the first type is a related responsibility main body involved in the supply process of various components of the fabricated building, and the other type is a related responsibility main body involved in the engineering design work of the fabricated building project.
Firstly, the construction project of the fabricated building cannot leave the prefabricated components, and the quality of the components and the construction quality of the fabricated building have a very close relationship. The manufacturing method mainly relates to a production party and a transportation party which are responsible for the parts from production to a construction site, and for the production party, the production party is responsible for ensuring the production quality of the parts, and for the parts which do not meet the requirements, self-checking and rechecking are required to be carried out, so that the parts with unqualified quality are prevented from flowing into the market. When a transportation party in a production direction delivers component products, the transportation party (or other responsible parties) should check and confirm the quantity and quality of the components delivered from the factory, and store the final authentication result as a supply information record of the production party. Similarly, since the components may be damaged during transportation due to collision or the like because of improper stacking, non-responsibility for transportation, or lack of due transportation protection measures during transportation of the components, when the components are received by a construction party of a project, the quantity and quality of the components transported to the construction site need to be checked and confirmed, the specific detection items and criteria are the same as those described above, and the result of the checking is also stored as a supply information record of the transportation party. Through the above embodiment, the supply information of the whole delivery and transportation processes of the components can be summarized and recorded in the preparation work before the assembly type building construction. The method is very beneficial to determining the responsibility subject when the supply quality of the structural parts has problems, and facilitates the responsibility tracing of the quality problems caused by the structural parts in the construction quality tracing of the fabricated building. Meanwhile, factory supply information and transportation supply information of the components are effectively collected and stored, and uploaded to an information interconnection and intercommunication assembly type building construction project alliance chain for distributed accounting, so that information can be effectively prevented from being distorted, and the safety and information symmetry of responsibility tracing are enhanced. It should be noted that the division of responsibility in the embodiment of the present invention is only an alternative embodiment, which only represents that the quality tracing can be performed according to the above method, and the actual division of responsibility is performed according to a specific multi-party protocol or related regulations. Similarly, the design information provided by the constructor, such as drawing files, quality planning, data calculation support, etc., should also be used as information for tracing the responsibility of the designer to make effective accounting.
Further as a preferred embodiment, the step S2 of generating the second bill according to the node information of each preset quality tracking node in the assembly building construction process specifically includes:
s21: building model information of each preset time and preset key position is collected through a BIM model;
s22: acquiring patrol record information of an assembly type building construction site;
s23: and generating a second bill based on the building model information and the routing inspection record information.
Further, as a preferred embodiment, the method further includes an internet of things initialization step S7, where the internet of things initialization step S7 specifically includes:
s71: acquiring structural parts of an assembly type building, and uniformly coding the structural parts;
s72: installing a sensing layer label facility carrying independent identity information in the component, and importing the identity information into an information database of a BIM (building information modeling) model;
s73: and acquiring the position information of the sensing layer label facility through the identification device, and importing the position information into an information database of the BIM model.
In the embodiment of the invention, the building quality in the construction process is tracked from two aspects, on one hand, based on a Building Information Model (BIM) technology and an Internet of things technology, relevant information data and position information of construction parts in the assembly type building construction process are used as a model foundation, a building model is established, and then, the exact information contained in the building is simulated by using digital information. Through the BIM technology, the information of each single construction part serving as a basic building element can be combined into a database, and the data in the database is always kept consistent and is globally shared. By uniformly coding the construction and accessory parts and installing sensing layer label facilities carrying independent identity information, a construction and accessory part information database corresponding to a construction project can be effectively established. The sensing layer label facility can be implemented by any one of the methods including a two-dimensional code label, an RFID label, a camera, a GPS, a sensor, an M2M terminal, a sensor gateway and the like. Through the recognition device corresponding to the sensing layer label facility, the position information of the sensing layer label facility is obtained, and the position information is imported into the information database of the BIM model, so that the geometric figure information of the building parts can be gathered together to form a datamation building primitive containing abundant building project information. And BIM model information is correlated and dynamically changed, so long as the model information is changed, all the related objects can be updated rapidly, and corresponding graphs, documents and the like can be automatically generated.
Acquiring a building model of each preset time node, such as some preset time limit of a project, through a BIM model; or the information of some key positions, such as important parts of the building and detailed model information of interfaces, can be used as an index for quality monitoring in the construction process of the fabricated building. On the other hand, the construction quality of the prefabricated building is closely related to the field operation condition, and the quality problem may be caused by the fact that the construction personnel do not reach the standard for the operation of the machine, lack of necessary attention to the key parts of the prefabricated building and unskilled technology, so the inspection record information of the construction field should be used as an index for quality monitoring in the construction process of the prefabricated building. The patrol personnel who patrol the record information can be assigned by the relevant responsibility body.
Referring to fig. 2, as a further preferred embodiment, the step S5 of performing distributed billing on the first bill, the second bill and the third bill specifically includes:
s51: performing identity authentication on each participant of the assembly type building construction project, and generating a key pair comprising a private key and a public key for each participant after the authentication is passed, wherein the participants are all accounting nodes; the participants comprise a producer, a transporter, a designer, a constructor and a supervisor;
s52: when a production direction transporter delivers a component product, a digital signature is generated according to factory supply information of the component product and a private key of a producer; then the digital signature and the public key of the producer are sent to an authentication server together; the authentication server verifies whether the factory supply information of the component product is legal or not by using the public key, and if the factory supply information of the component product is legal, the authentication server generates a digital fingerprint from the factory supply information of the component product and writes the digital fingerprint into the block alliance chain together with a corresponding timestamp; finally, the timestamp is broadcasted to other participants in the alliance chain;
s53: after the transporter acquires the information broadcast by the producer through the alliance chain, calculating the hash value of the factory supply information, comparing the hash value with the digital fingerprint of the factory supply information acquired through the alliance chain, and if the comparison is successful, extracting the factory supply information; generating a digital signature according to the transportation supply information and a private key of a transportation party, and sending the digital signature and a public key of the transportation party to an authentication server; after receiving the transportation supply information, the authentication server verifies whether the transportation supply information is legal, if so, the authentication server generates a digital fingerprint from the transportation supply information and writes the digital fingerprint and a corresponding timestamp into the block alliance chain; finally, the timestamp is broadcasted to other participants in the alliance chain;
s54: when a design direction constructor delivers a design scheme of the fabricated building, generating a digital signature according to design information of the fabricated building and a private key of the designer; then the digital signature and the public key of the designer are sent to an authentication server together; after receiving the design information, the authentication server verifies whether the design information is legal, if so, the authentication server writes the design information and the corresponding timestamp into the block alliance chain; finally, the timestamp is broadcasted to other participants in the alliance chain;
s55: after the constructor obtains the broadcast information through the alliance chain, the hash value of the information is calculated and compared with the digital fingerprint of the information obtained through the alliance chain, and if the comparison is successful, the information is extracted; generating a digital signature according to the building model information, the routing inspection record information and a private key of a construction party; then the digital signature and the public key of the construction party are sent to an authentication server; after receiving the building model information and the routing inspection record information of the construction party, the authentication server verifies whether the building model information and the routing inspection record information are legal or not, and if the building model information and the routing inspection record information are legal, the authentication server writes the building model information and the routing inspection record information and corresponding timestamps into the block alliance chain; finally, the timestamp is broadcasted to other participants in the alliance chain;
s56: after acquiring the information broadcast by the construction party through the alliance chain, the proctoring party calculates the hash value of the information broadcast by the construction party and compares the hash value with the digital fingerprint of the information acquired through the alliance chain, and if the comparison is successful, the information is extracted; generating a digital signature according to the acceptance record information and the private key of the proctoring party, and then sending the digital signature and the public key of the proctoring party to an authentication server; and after receiving the acceptance record information of the proctoring party, the authentication server verifies whether the acceptance record information is legal, if so, the authentication server writes the acceptance record information and the corresponding timestamp into the block alliance chain together, and finally broadcasts the digital signature and the corresponding timestamp to other participants in the block alliance chain.
Further as a preferred embodiment, the method further comprises the following steps: and according to the distributed accounting result, carrying out responsibility division on each responsibility main body in the assembly type building construction process to generate an intelligent contract.
