Building: including town residential buildings, malls, office buildings, rural residential buildings, industrial buildings, and the like.
The house construction is an important carrier for social management of natural people, legal people, events and the like and basic elements of urban operation. The digital building construction method has the advantages that the building construction objects are defined by digitizing the building construction, the city building construction base numbers are found, spatial relations, attribute data, business data and the like related to the building construction are provided for different managers and users, a digital base is intelligently built for city management, information sharing among departments is promoted, working efficiency of departments such as public security and city management is improved, and convenience is brought to mass business registration, obligation education, study position room assistance verification and the like, so that data multi-running is realized, and mass few running legs are realized.
04 Municipal utilities: including water supply facilities, power supply facilities, heat supply facilities, air supply facilities, urban volume sanitation facilities, fire-fighting facilities, urban public component facilities, etc.
Municipal utility facilities scatter at every corner of city, relate to the aspect of citizen's production life. The utility model has the advantages of digitalized municipal utility facilities, each common municipal utility facility can be used as a unique road sign, so that citizens can accurately position urban space, report the position of occurrence of an event accurately, and assist in improving municipal administration level.

The method has the advantages that the information infrastructure is digitalized, the safety protection and the efficient development and utilization of the key information infrastructure are served, and national safety, social stability and economic development can be promoted and guaranteed.
Therefore, the unified coding of the urban digital public infrastructure is a key link of the construction of the urban public infrastructure, the unified coding is used as a tie, government data resources scattered in each department are associated and accurately sunk to a base layer, the limits of azimuth, field and space and time are broken through, and the information barriers among organizations and platforms are broken. For example, sensing terminals such as sensors, cameras, intelligent terminals and the like monitor urban infrastructure, running conditions, traffic information, weather environments and the like in real time and acquire data.
However, since unified codes are not used among departments, institutions and manufacturers, the multi-modal data is difficult to be fused and expressed. Therefore, the establishment and use of unified coding is of great significance for achieving efficient operation and management of the urban digital public infrastructure.
The generation and exchange of the unified codes of the urban digital public infrastructure generally adopts a centralized mode, namely centralized generation codes and centralized exchange codes.
However, this centralized simple one-dimensional coding management mode faces many challenges in practical application, such as different management granularity of objects in different industries, different coverage of the same concept on objects in different industries, different periods of object change (including addition, splitting, combining, and extinction), and the like:
1. Challenges associated with managing granularity differently across industry objects: for example, urban digital public infrastructure includes a number of aspects of management units, land, buildings, municipal utilities, traffic facilities, water utilities, agricultural facilities, industrial and mining facilities, and information infrastructure. The management granularity of these facilities varies, for example, the management unit may need to be refined to the minimum management unit of a house, and the land may involve various types of land such as cultivated land, garden, woodland, grassland and the like. Because of the granularity, it is difficult to unify at which level the object association relationship should be established.
2. The same concept covers the challenges of maintaining association relations in different industries and in different ranges of objects: for example, for street lamps, the urban digital public infrastructure refers to the whole street lamp and the monitoring equipment attached to the street lamp, while for industries, some places are uniformly maintained by the same department, the lamp body of some places street lamps is possibly responsible for installation and maintenance by the urban management department, and the monitoring equipment on the street lamp is installed and maintained by the public security department. This requires a finer granularity of industry description, but should be aligned with the unified coding of this "street light" object in the urban digital public infrastructure. This results in difficult maintenance and history tracking of the relationship.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention. In addition, the technical features of each embodiment or the single embodiment provided by the invention can be combined with each other at will to form a feasible technical scheme, and the combination is not limited by the sequence of steps and/or the structural composition mode, but is necessarily based on the fact that a person of ordinary skill in the art can realize the combination, and when the technical scheme is contradictory or can not realize, the combination of the technical scheme is not considered to exist and is not within the protection scope of the invention claimed.
The block chain technology can realize the decentralization generation of codes, in the traditional centralized code management mode, the generation and distribution of codes are usually completed by a central mechanism, and the mode can face the problems of low efficiency, easy error and the like when processing large-scale and complex urban digital public infrastructure codes, and the decentralization characteristic of the block chain technology can enable the generation and distribution process of codes to be more efficient and accurate.
The blockchain technique enables secure storage and exchange of codes, which greatly enhances the security and reliability of the codes, because the data of the blockchain is not tamper-resistant, and once the codes are generated and stored on the blockchain, they cannot be modified or deleted. Meanwhile, the distributed characteristic of the block chain can realize safe and efficient exchange of codes, and the problem of single-point failure in the traditional centralized exchange mode is avoided.
Blockchain techniques may also enable cross-industry association binding of codes. In the conventional coding management mode, coding of the same object in different industries may be different due to possible differences of coding systems in different industries, which makes data fusion across industries difficult. The block chain technology can associate and bind the unified code of the urban digital public infrastructure with the unique industry codes of the urban digital public infrastructure in different industries and trace back histories, so that multi-mode data fusion expression across industries is realized.
Based on the above, the invention provides a universal identification code management system of a digital public infrastructure based on a blockchain, which comprises a code management mechanism, a plurality of region code issuing mechanisms, a region transaction management mechanism and users, wherein the code management mechanism and the region code issuing mechanisms are main nodes of the blockchain, as shown in fig. 1.
The code management mechanism is used for deploying intelligent contracts, canceling unified identification codes of public facilities and tracing the unified identification codes;
each region code issuing mechanism is used for issuing a unified identification code of the digital public infrastructure based on the intelligent contract;
The regional transaction management mechanism is used for applying for the regional code issuing mechanism to endow the digital public infrastructure with uniform identification codes and modifying non-key information of the coded objects;
the user is used for inquiring the brief information of the identification object according to the unified identification code.
It will be appreciated that the blockchain-based digital public infrastructure unified identity code management system consists essentially of 5 objects including a code authority, a plurality of region code issuers, a plurality of region transaction authorities, users, and intelligent contracts running on the blockchain.
The code management mechanism can be a provincial management mechanism, the region code issuing mechanism can be a administrative unit of a city-level management unified identification code, the region business management mechanism can be a city-county digital public infrastructure management unit, each functional department or public utility unit, and the like, and the user can be a common citizen user, or can be a city-county digital public infrastructure management unit, each functional department, public utility unit, and the like.
The code management mechanism has the highest right to manage codes, and can deploy intelligent contracts, cancel the unified identification codes of the digital public infrastructure and trace the unified identification codes. The area code issuing authority has authority to issue codes. The regional transaction director may apply for the authority to code related objects from the regional code issuing authority, as well as modify non-critical information of the coded objects. The user can query the profile identifying the object according to the universal identification code.
Referring to fig. 2, a block chain storage mode is a distributed storage mode, and both a coding management mechanism and a coding issuing mechanism are main nodes of the block chain, so that all block chain information is saved. The blockchains stored by each master node keep information consistent through a consensus mechanism, the blockchains in the invention are alliance blockchains, and the used consensus mechanism is a practical Bayesian fault-tolerant algorithm (PBFT algorithm). The distributed storage block chain ensures that the trust of the unified identification code coding information is not changed.
As shown in FIG. 3, a blockchain is made up of a plurality of blocks, each block containing a plurality of transactions, the first of which is a smart contract that can store transaction logic, such as issue coded logic flows. The second is general transaction information, such as brief information of a specific transaction manager, and the third is intelligent contract processing result, such as unified identification code and coded object brief information thereof.
The smart contract may be a piece of code stored on a blockchain that may execute some business logic, such as issuing coded business.
The general transaction information may be basic information of a department or user, such as a name, a private key, other encrypted information, etc.
The result of the intelligent contract processing is that a certain account initiates a request to the intelligent contract, and the intelligent contract processes success or failure information according to the request.
The transaction logic of the intelligent contract comprises an initialization intelligent contract flow, an encoding issuing and modifying flow and an encoding object information modifying flow. The initialization smart contract flow is shown in fig. 4. The code management organization issues intelligent contracts according to specific demands, and the intelligent contract contents comprise processing logic and regulations related to the specific demands and processing rights of different regional code issuing organizations. After the intelligent contract is deployed, the local code issuing mechanism stores the identity information and the code standard information of the intelligent contract into the intelligent contract, and after the code management mechanism verifies, the intelligent contract initialization is completed.
In the process of initializing the intelligent contracts by uniformly identifying code issuing, as shown in fig. 1, a regional code issuing mechanism needs to submit materials (mainly the identity information and the code standard information) to a code management mechanism, and after the code management mechanism passes the verification, the intelligent contracts of account binding authorities can be generated.
For example, one specific scenario: if the A city A bureau applies for the unified identification code to the province code management organization for the geographic entity code. After the provincial code management mechanism passes the verification, an intelligent contract is deployed, and relevant code authority is determined, for example, 6 bits before the code are required to be A municipal code, and 7-8 bits are required to be address major type identification; meanwhile, the intelligent contract is set that only the A city first office has authority to issue a unified identification code, and the B office and the C office have authority to delete and check related information according to the codes. This way of encoding on the blockchain guarantees the authority of encoding and does not repeat encoding at the same time.
The unified identification code issuing and modifying flow is shown in fig. 5, and the regional transaction authorities submit materials to the regional code issuing authorities, which audit the materials and issue the unified identification code to the blockchain through intelligent contracts, and the intelligent contracts notify the related regional transaction authorities to verify after issuing the unified identification code. After the transaction authorities in the relevant areas verify the unified identification code relevant information, if no objection exists, ending the flow; if the objection is present, the objection can be submitted to the intelligent contract, at this time, the regional code issuing mechanism and the regional transaction management mechanism do preliminary off-line negotiation, after the negotiation, the regional code issuing mechanism negotiates with the code management mechanism off-line, after the negotiation, the code management mechanism makes a decision of canceling the code or refusing the objection according to the negotiation result, and records the processed result in the block chain. Wherein, if the negotiation result is to cancel the unified identification code, the related information is recorded in the blockchain, such as transaction type, transaction content and the like, and the transaction content comprises cancel content, cancel reason and the like.
In the unified identification code issuing and modifying process, all information between the unified identification code and a certain code object can be endowed and modified, wherein the information comprises key matching information and non-key matching information between the unified identification code and the code object.
For example, in the geographic entity coding information input by the A city coding issuing mechanism, the key matching information comprises a unified identification code and a geographic entity unified address, and the non-key matching information comprises a geographic entity photo, other specific information database addresses of geographic entities and the like.
In the unified identification code issuing process, unified identification code information input by a region code issuing mechanism must meet defined regulations and logic in the intelligent contract, otherwise, the intelligent contract fails to execute, and a result is recorded in a blockchain.
If the code information recorded by the A city code issuing mechanism is coded into 000001 and the intelligent contract is coded into 000002, the execution fails.
If a code is recorded by the A city code issuing mechanism, logic for searching the code uniqueness exists in the intelligent contract in the database, and execution failure is judged. This way the uniqueness of the code is guaranteed.
The unified identification coding object non-key information modification flow is shown in fig. 6, the regional transaction master initiates an application for coding object non-key information modification to the intelligent contract, the intelligent contract modifies related information according to the request, and the modification result is recorded in the blockchain. In the non-key information modification flow of the unified identification coding object, the regional transaction authority does not have the right to modify key matching information between the unified identification coding and the coding object.
If a certain geographic entity managed by the A city A office is changed into a high building from a flat house, the A city A office can initiate application to the intelligent contract, modify the photo in the corresponding unified identification coding service, the geographic entity picture is non-key matching information, the intelligent contract can judge that the execution is successful, and record the result into the blockchain.
If the application is initiated by modifying the geographic entity unified address, and the geographic entity unified address is the key matching information, the intelligent contract determines that the execution fails and records the execution failure into the blockchain.
The method for encoding the digital public infrastructure in the intelligent contract comprises the following steps: using the line classification method, the digital public infrastructure objects are uniformly coded, as shown in fig. 7, with a total of 24 bits identified uniformly. The coding adopts 16-system numbers, and the numbers 0-9 and the letters A-F are used for identification. Wherein the 1 st to 6 th codes represent region codes, the 7 th to 8 th codes represent class 1 codes, the 9 th to 11 th codes represent class 2 codes, the 12 th to 14 th codes represent class 3 codes, the 15 th to 23 th codes represent sequence codes, and the 24 th check bits.
