Description

Civil aviation airport settlement system and method based on blockchain platform alliance chain

Technical Field

The invention belongs to the technical field of civil aviation settlement, and particularly relates to a civil aviation airport settlement system and method based on a block chain platform alliance chain.

Background

In recent years, the throughput of civil aviation passengers is greatly increased, the airport scale is continuously enlarged, the complexity of service organization is continuously increased, and higher requirements are put on the informatization capability of the whole civil aviation industry. Therefore, constructing an airport group to form the cooperative coordination and data sharing of airports, air enterprises, air pipes, various security departments and joint inspection units, obtaining the overall efficient coordination of civil aviation operation becomes a key for accelerating the intelligent construction of the airports. Blockchains have been infiltrated into applications in all industries as independent technology stacks that integrate cryptographic principles, peer-to-peer networks, consensus mechanisms, and distributed storage.

The civil aviation industry has the characteristics of strong systematicness, more participation in cooperative bodies, large data volume, long service chain and the like, and accords with the characteristics of research and development of the blockchain technology. Therefore, the digital economy is actively developed, global overall planning is promoted by means of a good informatization basis, the international speaking right and rule making right of civil aviation are promoted in the field of block chain technology and industrial innovation development, and the method is the direction of effort in the current and future quite long time of the civil aviation industry.

Furthermore, the settlement of civil aviation main service mainly has three settlement modes, namely self settlement, settlement through a civil aviation bureau clearing center and settlement through a China aviation settlement limited responsibility company. Self-settlement is the most common settlement mode, settlement work is carried out by contractors according to contracts, and aviation industry generally takes service side/provider provided bills and service/handover ticket attachments as main components, and independent settlement is carried out according to contracts.

The settlement is carried out through the civil aviation bureau clearing center, and the main responsibility of the civil aviation bureau clearing center is to provide fund clearing service for civil aviation fund, administrative public utility charge, air traffic control charge and airport service charge, for example, in the settlement link of an airport and an airline company, the self-settlement is adopted under the condition of one-to-many due to the large number of the airlines, so that the airport can provide relevant bill to the China civil aviation bureau clearing center, the civil aviation bureau clearing center and the airline company carry out settlement and pay a certain proportion of commission, and meanwhile, a financial institution is introduced to provide receivables financing service.

The settlement is carried out by the aviation settlement limited liability company, and the Chinese aviation settlement limited liability company is mainly used for financial settlement and proxy settlement of domestic and foreign aviation passenger and cargo transportation, ground service, aviation oil, machine service, aviation transportation extension service and non-trade foreign exchange balance. Because the middle airline letters are responsible for the distribution link of the air tickets, related information is mastered, and if the airlines have interaction conditions such as passenger interchange, the airlines can be settled through the China aviation settlement limited liability company and pay a certain commission.

The settlement business of civil aviation plays a crucial role in the overall operation of the civil aviation, but there are a plurality of problems in the settlement business between airports and aviators and between aviators and aviators. Firstly, the efficiency is low, the settlement business volume is large, various documents are more, the business data is complex, a large amount of data still needs manual intervention processing, and the printing of various documents, the manual intervention processing and other factors also intangibly increase the economic cost in the settlement process. The unit for providing the upper month asking for money in the first three days of the month is very few in the industry; secondly, the settlement service has long chain, from the initiation approval of the money requesting party to the approval of the paying party, and then to the final settlement, the number of the process loops is large, the processing time of each link is long, and the account period agreed by the contract is added, so that the whole settlement period is as long as three months or even half a year. The sharing degree of the data of each party is low, the partial data is imperfect, and the problems of low credibility, difficult disputes and the like are also unavoidable. In addition, after the civil aviation charging price is released, higher requirements are also provided for a flexible settlement mode while more space is provided for price adjustment and market guidance.

The current civil aviation settlement process has the problems of low efficiency, long account period, complicated flow, more disputes in the settlement process, less financing channels of small and medium-sized enterprises, high cost and the like.

Detailed Description

In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The invention may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit or scope of the invention, which is therefore not limited to the specific embodiments disclosed below.

The civil aviation airport settlement system and method based on the block chain platform alliance chain provided by the embodiment of the invention have the innovation points that:

in embodiment 1, based on technical characteristics and advantages of a blockchain and requirements of civil aviation airport settlement service, the invention provides the civil aviation airport settlement system based on the blockchain platform alliance chain, namely the civil aviation airport settlement system based on the FISCO BCOS alliance chain, which is provided by the embodiment, and provides various data services and service applications for airports and airlines, such as user management, flight management, airplane management, bill generation, bill audit and the like, by combining intelligent contracts, and data uplink is used for guaranteeing reliable sharing and synergy of block link point data. The method has the advantages of improving efficiency of settlement of civil aviation airports, shortening account period, simplifying flow, efficiently auditing, reducing cost and the like.

The civil aviation airport settlement system of the FISCO BCOS alliance chain takes financial business practices as reference samples for a financial blockchain cooperation alliance source-opening work group, performs module upgrading and function remodeling on the basis of a BCOS source-opening platform, and is a safe and controllable deeply customized blockchain bottom layer platform which is suitable for the financial industry and is completely source-opening.

Blockchain (blockchain) is a distributed database system that is engaged by multiple independent nodes, also known as a distributed book (distributed ledger technology, DLT for short), that is commonly maintained by these nodes. The method is characterized in that the method is difficult to tamper, difficult to forge and traceable, the blockchain records all information of transaction, the process is efficient and transparent, and the data is high in safety. The blockchain technique can be applied to all application fields requiring fairness, fairness and honest.

Blockchains are classified into public chains, private chains and alliance chains in categories, with the core difference being the degree of openness of the access rights. The public chain nodes are opened to anyone, and the public chain nodes are characterized by high decentralization, high safety, low transaction efficiency, transparent data disclosure and inapplicability to a large number of public-to-public data privacy processing services. The alliance chain is only limited to participation of authorized alliance members, and the data processing speed is faster than that of a public chain, but the data processing speed is not completely decentralised, the alliance chain essentially belongs to a private chain, and only the authority design requirement is more complex and more credible. Therefore, the multicentric licensed network alliance chain takes advantages of public chains and private chains into consideration, has the characteristics of high performance, multicentric property, safety, reliability and the like, and is more suitable for application scenes of settlement business of civil aviation industry.

In order to accelerate the research and development of the alliance chain bottom technology, the technology accords with the autonomous and controllable strategy of China, promotes the application of the blockchain to the ground in various industries, is condensed in the technical field of the blockchain, improves the Chinese strength, and is created by the alliance chain bottom technology platform FISCO BCOS constructed by the gold chain alliance. The structure of the FISCO BCOS is shown in FIG. 1. On the whole architecture, the fsco BCOS is divided into a base layer, a core layer, a management layer and an interface layer.

Base layer: a base data structure and algorithm library for a blockchain is provided.

Core layer: the core logic of the blockchain is realized, and the core layer realizes the chain data structure of the blockchain, the transaction execution engine, the storage drive and the communication among nodes.

Management layer: and the management function of the blockchain is realized, including parameter configuration, account book management and AMOP.

Interface layer: and the block chain user is oriented, and an RPC interface and an SDK of various protocols are provided. The FISCO BCOS is based on a clear modular design, enabling blockchain developers to implement specific applications faster and to bring the application into practical industrial use. Therefore, the invention selects the FISCO BCOS alliance chain technology as the underlying foundation of the alliance chain for development and implementation.

The civil aviation airport settlement system based on the block chain platform alliance chain provided by the embodiment of the invention adopts a multicentric permission type network alliance chain, takes data providers of airlines, airports, flight streams and passenger streams as block chain nodes, and constructs alliance chains of nodes of airlines, airports, civil aviation office operation monitoring centers, empty pipe data centers, china aviation settlement finite liability companies, civil aviation settlement centers, civil aviation large data centers, third party platforms, financial institutions and the like. As shown in fig. 2, the system architecture is divided into, from bottom to top: the system comprises a data access layer, a data service layer and an application layer, wherein the data service layer is divided into a cloud service layer and a alliance chain service layer.

the data service layer is formed by adopting a FISCO BCOS blockchain and a dream database for storing query fields and transaction value mapping; flight information, baggage information, user information, merchant information, and intelligent contracts are stored in a blockchain; the mapping relation between the query field of the data information and the transaction hash value thereof is stored in a dream database; when inquiring, firstly, the corresponding hash value is searched in the dream database according to the inquiring condition, and then the corresponding data is searched in the blockchain according to the hash value, so that the efficiency and instantaneity of the civil aviation business transaction inquiring are met;

Illustratively, the data access layer essentially accomplishes the task of obtaining and uploading information of funds flows, information flows, flight flows (passenger and goods mail), business flows, and the like to the data services layer. The flight flow is the core of the current settlement business, and surrounds various service fees generated by completing a flight task of an airplane, such as a series of fees of aviation business fees (taking off and landing fees, stop fees, bridge fees, passenger service fees, security check fees) and non-aviation business fees (first class cabins, business class cabins, office service rentals, ticket counter rentals, cabinet counter rentals, ground service fees) and the like. As shown in fig. 3, the data uploading may input data information through the front-end operation interface, call the intelligent contract address service interface, and upload the data to the located blockchain node by using the ICP/IP network protocol according to the geographic location of the user, thereby completing the uploading of the service data to the alliance chain.

The data service layer, the block chain bottom data storage is stateless, and the required transaction hash value cannot be directly obtained from the block. The method for establishing mapping from the query field to the transaction hash value by adopting the intelligent contract requires multiple times of calling interface scripts to communicate with the blockchain, so that the efficiency is low, and the efficiency and instantaneity of transaction query cannot be met under the condition of high concurrent query of the civil aviation airport group. Therefore, the data service layer of the system is formed by adopting the FISCO BCOS blockchain and the dream database as the mapping, and the structure of the data service layer is shown in figure 4. Wherein the flight information, baggage information, user information, merchant information, and smart contracts are stored in a blockchain. The mapping relation between the query field of the data information and the transaction hash value is stored in the dream database. When the user executes one-time checking all data or inquiring data, the background will search the corresponding transaction hash value in the dream database according to the inquiring field, and then search the corresponding data of the corresponding transaction in the blockchain according to the transaction hash value and display. When data is uploaded to the blockchain, the API calls a storage function in the intelligent contract to encapsulate the data object into a transaction and encrypt the transaction into a 16-ary random sequence, and then broadcasts the transaction in the whole blockchain network. After the nodes of the whole network airport and the navigation department agree on the transaction, the block packed with the transaction is accessed into the block chain of each node.

The alliance chain service layer is used for providing alliance chain transaction service to the outside and maintaining alliance chain account book data to the inside. The federation chain network layer is made up of a plurality of federation link points. Under the action of a consensus mechanism, the data in the alliance chain is synchronized into a distributed cluster formed by a plurality of alliance chain nodes, and the alliance chain service layer realizes the addition, deletion and modification of the data in the alliance chain through an intelligent contract and provides an interface for the cloud service layer to call the intelligent contract, so that the security operation of the alliance chain data is realized. In the present application, the federation chain service layer is implemented using the FISCO BCOS federation chain technique.

The cloud service layer provides cloud services, and the cloud services comprise external account management and intelligent contract calling services. The cloud service layer plays a role of middleware in the application, namely, the cloud service provides an API interface for the application layer, the Https request from the application layer is processed, meanwhile, the cloud service layer directly interacts with the alliance chain service layer, and the cloud service layer invokes an intelligent contract through the alliance chain interface to realize business logic. In this way, the cloud service layer implements decoupling of the application layer and the federated chain service layer. This allows the user to mask the complexities of the federated chain service layer without requiring excessive additional learning when using federated chain-based applications.

Illustratively, the processing the Https request from the application layer includes: the client accesses the API interface of the server, calls the corresponding API interface according to different request types of the client, and accesses the server, for example: the client stores the flight information, calls an API interface corresponding to the flight information storage, and uploads the flight information to the server through the flight information storage interface;

the invoking the intelligent contract to implement business logic includes:

(4) After the fee bill is generated, the two parties can carry out-of-chain transaction, the in-chain bill data is bound with the out-of-chain settlement instruction, and a third party which is trusted and reliable is introduced to complete the settlement transaction; the user does not need excessive extra learning when using the application based on the alliance chain, the complexity of the alliance chain service layer is shielded, the uplink and the query of airport financial settlement data can be conveniently and rapidly realized only by using an API interface, and the alliance chain service layer does not need to be directly operated, so that the decoupling of the application layer and the alliance chain service layer is realized.

The application layer provides an interactive interface for a user, so that the user can better use the service provided by the cloud service layer, and the user can better perform data interaction with the cloud service layer.

According to the embodiment, the fund turnover efficiency can be improved by building the civil aviation settlement blockchain, and the credit radiation range of enterprises can be enlarged. Thereby realizing the aims of reducing financing risk, reducing financing cost and improving financing efficiency. And the settlement efficiency is improved, and quick benefits are obtained.

The invention is a big application of the FISCO BCOS alliance chain technology and the domestic dream database in civil aviation settlement business, which can realize the improvement of the efficiency of the civil aviation airport settlement, shorten the account period, simplify the flow, efficiently audit and reduce the cost.

After the technology based on the blockchain, the risk of the civil aviation settlement process is greatly reduced, the arrival of each settlement is known through the traceability characteristic of the blockchain, and the existence of the intelligent contract is added, so that the settlement bill becomes unique, highly reliable and effective.

Embodiment 2, as shown in fig. 5, the civil aviation airport settlement method based on the blockchain platform alliance chain provided by the embodiment of the invention includes:

s1, deploying an intelligent contract in a alliance chain by writing an intelligent contract code to generate an intelligent contract calling address, wherein the alliance chain stores service data of civil aviation settlement; the user invokes an intelligent contract address service interface through the cloud service layer to operate the business data of civil aviation settlement in the alliance chain, and finally, the business data is reflected to a front-end user operation page; the intelligent combination is divided into: flight information management intelligent contracts, airport information intelligent contracts, airline information intelligent contracts, aircraft information intelligent contracts, contract information intelligent contracts, bill information intelligent contracts, and funds information intelligent contracts;

wherein, the intelligent contract mainly comprises the following steps:

the contract is predefined, and the contract terms are commonly contracted by all alliance members participating in the settlement business.

Triggering the contract, and executing the transaction when the contract receives the information and meets the conditions.

And generating a bill, wherein on the premise that the condition is met, the intelligent contract is automatically triggered, and the generation of a cost bill is performed according to contract terms according to the collected alliance node information.

And (5) settling accounts of both parties. After the fee bill is generated, the two parties can carry out-of-chain transaction, the in-chain bill data is bound with the out-of-chain settlement instruction, and a third party which trusts each other reliably is introduced to complete the settlement transaction.

Illustratively, in step S1, service data of civil aviation settlement is stored in a federation chain, data in the federation chain network is operated by an intelligent contract in a federation chain application, an intelligent contract code is written, the intelligent contract is deployed in the federation chain to generate an intelligent contract call address, a user calls an intelligent contract address service interface through a cloud service layer to operate the data in the federation chain, and finally the operation is reflected to a front-end user operation page.

It can be understood that intelligent contracts are introduced to achieve the execution effect of promoting and verifying settlement two-party agreements, and the performance risk can be effectively managed and controlled. The intelligent contract can rapidly execute transactions, has high settlement efficiency, saves a great deal of labor cost, reduces the economic cost of the settlement process, has high transparency to all participants on terms and execution conditions of the intelligent contract, and solves the dispute problem. 7 smart contracts were designed for 7 users in the system to meet different applications. The contract affiliation is shown in figure 6.

The intelligent contract for managing the flight information mainly records the information of the incoming and outgoing port information, the departure time, the stop time, the bridge time, the luggage number, the passenger number, the starting station, the destination station, the flight model, the number of the aircraft, the airline company and the like of the flight.

For example, in step S2, when the user performs alliance chain data access through the intelligent contract, in order to ensure data access security, the access authority of the user needs to be verified, and in the present invention, three nodes, namely, a primary node, a secondary node and a common node are designed. Each node has different authorities for accessing the intelligent contract function, and in order to reduce the intelligent contract function which the user override access does not belong to, the invention designs the intelligent contract authority access control applied to civil aviation settlement service according to the node role access control and the intelligent contract.

In step S2, the master node of the entire civil aviation settlement alliance chain is a data provider, has a full-volume data file, and alliance members who do not want to participate in or need to participate in full-volume data synchronization are taken as secondary nodes, only block chain data related to the master node is synchronized, and a third-party financial institution is taken as a common node and is limited to checking related bills; the master node or the appointed node with better calculation capability is used as a billing person, and according to actual operation data generated in the whole process of taking off and landing the flight, an intelligent contract is matched to carry out a clear-after-flight mode to form a settlement instant confirmation and write-in block; in the block generation process, a main node packages and broadcasts a plurality of flight information, a node which has a high-performance computing technology and can meet the requirements and efficiency of airport financial settlement data quantity is regarded as a node with better computing capability, and in a main data provider, a large airport and an airline company with stronger comprehensive strength, the part of alliance members have better support on a hardware equipment network and also have certain capability to jointly maintain the ecology of a civil aviation settlement alliance chain, and the node belongs to the node with better computing capability. After receiving the broadcast block information of the main node, the node with better computing capability computes a specific consensus algorithm to confirm, and the application selects the PBFT consensus algorithm in the FISCO BCOS block chain to perform consensus confirmation. Writing into a block chain to form a new block; the new block continuously receives the common verification of other nodes in the whole network broadcasting process, and after the continuous quantity is confirmed, the whole network node determines whether to synchronize the block according to the respective requirements.

Related institution nodes serving as common nodes are added to a alliance chain network through permission authorization, and the functions of reading and writing account books of all the institution nodes are managed and controlled by using account book authorities or legal identity certificates, so that once the account books are successfully written, the account books cannot be tampered; the method is characterized in that all account book data on the alliance chain are highly encrypted, and only alliance members view the account book data by themselves, and the obtained data are decrypted through authorization when the alliance members reading other node data.

In step S3, the information uplink includes: users of the primary node and the secondary node can perform information uplink; the common node user only carries out the uplink of fund information; after the server side interface script receives the uplink information, a corresponding intelligent contract and a contract function are called, and the data information is packaged into a transaction object and uploaded into a blockchain;

As shown in Table 1, the master node of the entire civil aviation settlement alliance chain is a data provider and is provided with a full data file, such as a civil aviation office operation monitoring center, an empty pipe data center, a civil aviation big data center and the like. Coalition members who do not want to participate or need to participate in full data synchronization can act as secondary nodes to synchronize only blockchain data related to themselves, such as large airlines, airports, and third party financial institutions act as ordinary nodes only, limited to viewing related bills. The main node or the appointed node with better calculation capability can be used as a billing person, and the real operation data generated in the whole process of taking off and landing the flight, such as taking off time, landing time, flight number, destination, passenger number, cargo number and the like, are matched with an intelligent contract to carry out a real-time clearing mode to form a settlement instant confirmation and write-in block. In the block generation process, the main node packages and broadcasts a plurality of flight information, and after receiving the broadcast block information of the main node, the node with better operation capability calculates a specific algorithm to confirm, and writes the broadcast block information into a block chain to form a new block. The new block continuously receives the common verification of other nodes in the whole network broadcasting process, and after the continuous quantity is confirmed, the whole network node determines whether to synchronize the block according to the respective requirements.

Table 1 the user access rights control table provided by the embodiment of the invention

。

Financial institutions act as third parties between large airlines and airports, and only query and confirm relevant bills after joining in the settlement business blockchain, so that creditors (such as airports) can be pre-paid, and the problem of cash reservation of middle and small airports and small micro-enterprises can be solved. After receiving payment, the creditor (such as airport) transfers the creditor to the financial institution, and the financial institution carries out additional discussion on the settlement amount of the creditor. Of course, the creditor (such as airport) needs to pay corresponding commission to the financial institution, which is higher than the deposit interest rate of advance payment, and the commission can be correspondingly reduced in large airports with more settlement business. The mode is also suitable for settlement business among airlines, passenger and cargo agents and airlines, in the mode, once settlement amount in a blockchain is generated, after bank verification is passed, the airport, the airlines or other units can receive the settlement amount very fast, and the bank also obtains a certain profit.

The related organization nodes are added into the alliance chain network through permission authorization, the node credibility is guaranteed, the account book authority or legal identity certificates are utilized to manage and control the functions of reading and writing account books of all the organization nodes, and once the account book writing is successful, the account book cannot be tampered. All account book data on the alliance chain are highly encrypted, only alliance members view the account book data by themselves, the alliance members needing to read other node data can decrypt and acquire the data through authorization, and the data security is ensured.

Illustratively, in step S3, the information uplink includes: users of the primary and secondary nodes may perform information chaining. The regular node users can only perform the uplink of fund information. And after the server side interface script receives the uplink information, calling a corresponding intelligent contract and a contract function, packaging the data information into a transaction object, and uploading the transaction object into a blockchain. The user can choose whether to store the mapping relation between the query field and the transaction hash value in the dream database so as to improve the retrieval speed.

The service data query includes: airport, airline users can query flight information, airport information, airline information, aircraft information, contract information, billing information, and funds information stored in the blockchain. The third party financial institution may view billing information and funds information in the blockchain. If the information which the user wants to inquire stores the mapping relation between the inquiry field and the transaction hash value in the dream database in advance, acquiring the corresponding transaction hash value from the dream database according to the inquiry field, and calling the intelligent contract and the contract function to inquire the corresponding transaction by taking the hash value as a parameter; if the mapping relation is not stored in the dream database, the intelligent contract and the contract function are called by taking the query field as parameters to query the corresponding hash value, and then the contract function is called to query the corresponding transaction according to the hash value.

The civil aviation settlement alliance chain operation mechanism is based on the blockchain technology, the risk of the settlement process is greatly reduced, the going of each settlement is known through the traceability characteristic of the blockchain, and the existence of the intelligent contract is added, so that the settlement bill becomes unique, highly credible and effective. In a word, the efficiency and the cost can be improved and reduced in the aspects of intelligent contracts, payment settlement business, financial services and the like of the civil aviation industry chain through the blockchain technology, more and updated derivative financial products and services are provided, and the system contributes to the development of the civil aviation.

It can be understood that the invention applies the alliance chain technology to civil aviation settlement business, reduces the cost and increases the efficiency, increases the credibility and the effectiveness of the account book, ensures the data safety, effectively controls the risk of performing, and accelerates the intelligent construction of airports.
