Detailed Description
The technical scheme of the invention is further explained by combining the attached drawings in the embodiment of the invention.
The house decoration supervision system based on the block chain comprises a house decoration supervision alliance chain, and a decoration party information storage unit, a user interaction unit, a decoration supervision unit and a user evaluation unit which are established on the alliance chain. In the alliance, Hyperridge Fabric which is dominated by a Linux foundation is used as a bottom layer blockchain system to complete the establishment of the bottom layer platform.
The nodes for house decoration transaction and supervision alliance chain inclusion comprise: building material wholesalers, decoration companies, construction teams, regulatory agencies (e.g., government and industry associations such as the bureau of housing and government, the bureau of construction, the office of housing and construction), and third party organizations (e.g., the judicial evidence-storing center). The nodes maintain the stable operation of the whole alliance chain together, and each node can be divided into a full node and a light-weight node according to different informatization construction levels. All data on the chain are recorded by the full nodes, and the lightweight nodes only record the key data and the Hash values of all the data and are used for verifying the accuracy of the data. And setting different rights and rights according to different nodes, so that the nodes contributing a large amount to the alliance are provided, and the speaking right and the income in the alliance chain are increased. The supervising node can view the data in the federation chain that needs to be supervised. And (3) adopting an Ubuntu 16.04 operating system to construct a HyperLegend Fabric and an operating environment (such as Golang, Docker and the like) thereof by each node to complete the construction of a bottom layer system.
The decoration side information storage unit is a distributed storage unit built based on data storage capacity provided by Hyperridge Fabric. The following information is included: the registration capital, registration age, personnel information, decoration style, quotation information and the like of the decoration company. The personnel information includes information of main managers of the decoration company, information of a design team and information of a construction team. The design team information comprises previous design sample and finished product display, construction area and design, raw material use condition and current market quotation. The construction team comprises information such as team establishment time, construction project quantity, construction team evaluation and the like.
The user interaction unit mainly comprises a user registration module, a task issuing module and a supply issuing party. The user registration module allows users to register third-party account numbers such as mobile phone numbers and mailbox numbers, so that each user has a unique identity on the chain, and Sybil attack can be effectively prevented. In order to improve the efficiency of achieving the transaction, two issuing modes are designed. One is a task release mode that a user releases a self decoration task to a chain, wherein the chain comprises information such as a decoration budget, size information of a house to be decorated, a decoration material grade, a finishing date and the like for bidding of a decoration company; and the other is a supply distribution mode that a decoration company distributes the design sample of the company for the selection of the user. In order to prevent the decoration companies from bidding widely in the task release mode, each decoration company is limited to only bidding for five tasks every day, and information such as a design team, a design thought, a construction team, expected construction time, bidding price and the like needs to be provided for the bidding tasks. This information will be sent to a mailbox where the user is pre-reserved in the system, if the user is interested in the design, deep interaction can be done on the chain or further investigation under the chain.
The fitment supervision unit is a main unit of the invention. Each finishing project in the invention has a unique project ID, and each project has a unique Channel. The channels are isolated from each other, and a node connected to one channel is unaware of the existence of other channels, but a node may be connected to multiple channels. The repeated chain establishment can be effectively avoided through the channel technology, and the mutual independence and confidentiality of data among projects are ensured. Design schemes, contract contracts, construction materials, construction processes, acceptance results and full-process information of project evaluation of each project can be inquired on the chain through the ID of the project. A design scheme and a contract are uploaded to a block chain by a specially-assigned person for storage; construction materials need to upload information such as purchase orders, material grades and the like to a block chain; data acquisition is completed through Internet of things equipment such as a camera in the construction process, and the acquired data are subjected to data cleaning and other operations to upload key information to a block chain for storage; and the acceptance result is to store the pictures of the finished room and the information of the content of harmful gas in the room in a period of time. If the harmful gas standard exceeding measuring instrument sends an alarm, the system sends mails and short messages to the mailbox and the mobile phone number reserved in the system by the user, and meanwhile, the detected data is stored in the block chain to be used as evidence for later maintenance. If the right maintaining scene is simple, the claim settlement process can be automatically triggered through an intelligent contract. For illegal acts, a competent department can implement corresponding punishment measures.
The user evaluation unit is an embodiment of a feedback mechanism. The user can evaluate decoration companies and construction teams through the unit, meanwhile, decoration companies in the alliance form an evaluation group, and anonymous mutual evaluation is completed according to on-chain data and actual investigation. And (4) publishing the evaluation result in a whole network, so as to standardize the behavior of the decoration company and improve the service quality of the decoration company.
The method comprises the following specific steps:
firstly, a Hyperled Fabric block chain network is built by utilizing a plurality of Ubunut 16.04 computers and an operating environment is configured. A set of house decoration transaction and supervision system based on a block chain is formed by combining the existing data storage technology and the data processing technology, and the service operated by the system comprises a decoration party information storage unit, a user interaction unit, a decoration supervision unit and a user evaluation unit.
The node type and the node number in each organization are reasonably set according to the number of the nodes in the alliance, and at least 12 servers provide services for the whole system in order to ensure the normal operation of the whole alliance. And the Go SDK is used for compiling chain codes, so that the requirements of a decoration party information storage unit, a user interaction unit, a decoration supervision unit and a user evaluation unit are met. And reasonably distributing the authority corresponding to the nodes in the block chain according to the work functions of the entity nodes, and completing the installation and instantiation of the intelligent contract on the nodes needing to run the intelligent contract, thereby ensuring the realization of business logic.
Each issued task is given a full chain unique ID number, which is a unique identification for searching and distinguishing tasks. For the task issuing mode, a user firstly creates a task, the system gives the task a unique ID number according to the difference of a creator and creation time, and the user is allowed to rename the task for the convenience of user management. Basic information such as a decoration place, a decoration area, a decoration style and the like is required to be uploaded during task creation for competitive bidding of decoration companies; supply distribution model, similar to Taobao B2C model, finishing companies distribute company profiles, design teams, construction teams, and past cases on a chain for user selection. The user and the decoration company can further discuss the decoration scheme and determine the decoration details on the chain or under the chain, and once the user and the decoration company sign a contract, the decoration design scheme and the design drawing are uploaded to the block chain and are permanently stored.
In the construction process, information such as purchasing information quality grades of decoration companies, construction teams and decoration materials is required to be uploaded to a block chain by a specially-assigned person for permanent storage, and data in the whole decoration process is acquired through internet of things equipment such as a camera and uploaded to a cloud for storage. Because the data volume collected by the Internet of things is huge and the noise information is more, the key information and the Hash value of the original data are uploaded to the block chain after the original data are cleaned.
In the decoration process or in a period of time after finishing decoration (mainly collecting indoor air quality and decoration effect), disputes or illegal behaviors occur, firstly, key data on a chain is called to be used as a basis for solving disputes or as an evidence for violation, and if two parties disagree with the key data, original data stored on the cloud is called. And after the original data are called, one-time Hash operation is firstly carried out, and the obtained result is compared with a Hash value stored on a chain, so that the data on the cloud are not changed. If the two parties can not solve the dispute in a consultation mode, the third party institution and the supervision department can intervene.
In order to promote the decoration company to improve the service quality and simultaneously acquire the real requirement of the user on decoration, the system also comprises an evaluation system. The user can evaluate the decoration progress in real time in the decoration process so as to promote a construction team to finish decoration projects in the time specified by the contract. After finishing the decoration, the user can carry out overall evaluation on the decoration company according to the decoration effect. In order to improve the service quality of the whole alliance and create alliance brands, an alliance evaluation group can be formed by nodes in the alliance (the speaking right of the nodes in the evaluation group is determined by contribution made to the alliance), and the decoration process and the decoration result are anonymously scored according to the on-chain data and the original data. In the final score, the user rating was 70% and the joint rating group was 30%, and for companies ranked 10% later in the rating, warning notices were issued, and companies ranked 10% later in consecutive 3 months consistently would prohibit the trade period from completing the correction in the next 3 months. If a second rectification occurs, the company will enter the blacklist for the federation chain.
Referring to fig. 1, the role of the system in house decoration transaction and supervision is shown. The system takes HyperLegger Fabric as a bottom platform. Encrypting data by using cryptography, and determining the ownership of the data by using a digital signature technology; the Block SQL is a database developed aiming at the characteristics of the block chain, so that the query and storage efficiency of data is increased, and the overall efficiency of the block chain is improved; the user management technology is embodied in the management capacity of account passwords, and a public-private key mechanism which is difficult to remember and use in a block chain is converted into an account password mechanism; the intelligent contract is that the block chain bottom platform has the capability of realizing specific service scenes, and provides technical support for the wide application of the block chain bottom system.
The alliance chain in the system consists of entity enterprises, supervision agencies and qualified third-party agencies involved in the decoration process. And determining the authority of each node on the chain according to the rights and obligations of the nodes under the chain, and ensuring the security and privacy of data on the chain. And setting the speaking right of the nodes in the evaluation group according to the contribution of the nodes in the alliance chain, and setting a corresponding reward mechanism to ensure the normal operation of the whole block chain system.
The system realizes the butt joint with the existing management system through the SDK/API, reduces the conflict with the existing office supervision system, unifies the management standard and reduces the link establishment cost. Characteristics unsuitable for storing large amounts of data due to the data structure of the blockchain itself. The system is combined with a cloud storage technology, original data stored in the Internet of things are stored in the cloud end, and key data subjected to data cleaning and the Hash value of the original data are stored in the block chain, so that the performance of the block chain is guaranteed, and meanwhile, the data cannot be tampered.
The application layer of the system mainly comprises a decoration party information storage unit, a user interaction unit, a decoration supervision unit and a user evaluation unit. The specific service module included in each unit calls different APIs (application program interfaces) to realize according to different application scenes, so that the expandability of the system is improved.
Referring to fig. 2, the usage flow of the system in the house decoration transaction and supervision system is shown. Wherein real-time supervision can be realized through the block chain. After data collected by the Internet of things equipment is cleaned and linked, a user can check the quantity, quality and construction speed of raw materials used by a construction party in real time, so that problems occurring in the construction process can be found in time, and error correction cost is reduced; the decoration company can master the working condition of a construction party in real time, the accurate assessment of staff is realized, and the staff with poor technical capability and low service level is found and processed in time, so that the overall service quality of the company is improved, and the brand image is improved; when a problem occurs in house decoration, the reason of the problem and related persons can be quickly located by utilizing the traceable characteristic of the block chain.
Referring to fig. 3, the manner in which data flows during the finishing process is illustrated. The process of generating the data comprises purchasing of building materials, transportation, storage and use of the building materials and inspection of decoration results, and the information needs to be linked up in real time to ensure that the data cannot be tampered. The building material purchase comprises information of building material types, building material quality grades, purchase quantity, prices, suppliers and the like; the transportation process comprises the name of a logistics company, the delivery time, a transfer station, the information of the transported building materials and the arrival time of the building materials; the storage process comprises the name of a storage company, information of stored building materials, storage conditions, start and stop dates of storage and information of storage responsible persons; in the using process, the complex networking equipment collects information such as construction unit information, types, quantity, using time, using positions and the like of used building materials; after finishing, it is necessary to detect the finishing quality and to detect the concentration of harmful gases over a certain period of time. For the original data recorded at the cloud, after the supervision value is lost when a certain time point is reached, the original data can be deleted according to the contract regulation, and the management cost of the original data is reduced.
A house decoration supervision method based on a block chain technology comprises the following steps:
s1: the user registration is used for enabling the user to have a unique identity on the chain, and the Sybil attack can be effectively prevented;
s2: the decoration company uploads and stores company information in a decoration party information storage unit;
s3: determining decoration intention on a chain by a user and a decoration company, giving a unique ID number to a decoration project, determining a design scheme, signing a decoration contract and uploading the contract to a block chain for storage and future reference;
s4: supervision of decoration materials, namely, a decoration company stores and looks up a block chain uploaded by purchased decoration material information;
s5: construction supervision, namely laying a camera on a construction site, acquiring field data, processing the data, and uploading the processed data to a block chain for storage and future reference;
s6: checking and monitoring, wherein a camera is used for shooting a scene picture, a detection instrument is used for detecting scene data and uploading the scene data to a block chain for storage and future reference;
