Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
With the increasing frequency of commercial and trade activities, the ship leasing industry is also beginning to develop rapidly. However, at present, when renters and lessees conduct ship leasing transactions, the renters and the lessees usually need to rely on intermediaries familiar with the business, so that the ship leasing process is complicated, and the quick execution of the ship leasing business is not facilitated. In order to solve the above problem, an embodiment of the present invention provides a method for leasing a ship.
Fig. 1 is a schematic flow chart of a ship leasing method according to an embodiment of the present invention. As shown in fig. 1, the method includes:
s1, acquiring the ship leasing information, wherein the ship leasing information comprises leasing demand information of a lessor and leasing demand information of the lessee;
s2, recommending optional ships to the lessor based on the renting demand information and the renting demand information, and generating an intelligent contract after receiving a target ship selected by the lessor from the optional ships and after the lessor signs a contract with the lessor on line;
and S3, deploying the intelligent contract to a block chain, and monitoring the ship leasing transaction between the lessor and the lessee based on the intelligent contract.
Specifically, in the ship leasing method provided in the embodiment of the present invention, an execution subject is a server, the server may be a local server or a cloud server, and the local server may specifically be a computer, a tablet computer, a smart phone, and the like, which is not specifically limited in the embodiment of the present invention.
Step S1 is executed first, and when the lessor and the lessee perform the ship leasing transaction, the ship leasing information needs to be acquired. The ship leasing information may include leasing demand information of a lessor and leasing demand information of a lessee.
The lessor rental need information of the lessor means information for representing lessor needs, and may include basic information of a ship for lessor rental. Such as the name of the vessel, the state of the vessel, the tonnage of the vessel, the navigable routes and the dockable ports, etc. The renting demand information of the lessor can also comprise rentable time, rentable space, expected renting price and the like of a ship used for renting by the lessor.
The tenant demand information of the tenant refers to information for characterizing the tenant demand, and may include basic information of a ship that the tenant needs to lease. For example, the tonnage and status of a ship to be rented, a route to be traveled, and a port to be parked midway are provided. The tenant's tenant demand information may also include the time the tenant expects to use a ship, the number of bays the tenant needs to use, the tenant's budget, and so on.
The renting demand information of the lessor and the renting demand information of the lessor can be stored in a pre-established database, and the process of obtaining the ship renting information can be a process of extracting and calling the stored renting demand information of the lessor and the stored renting demand information of the lessor through a database interface. The database may be any one of a hierarchical database, a network database and a relational database, and the data storage format may also be set according to the actual situation, which is not specifically limited in the present invention.
Then, step S2 is executed, and after the rental requirement information and the rental requirement information are obtained, optional ships, the number of which may be multiple, can be recommended to the lessee according to the obtained information. The lessee can select a ship meeting the requirements from the selectable ships, and the ship selected by the lessee is the target ship. After the lessee selects the target ship, the lessee and the lessee can sign a ship leasing contract on line. And after the signing of the ship leasing contract is finished, generating an intelligent contract based on the relevant information of the ship leasing contract.
When an optional ship is recommended to a lessee, the lessee demand information provided by the lessee needs to be matched with the lease demand information provided by the lessee. For example, ship information provided by existing lessors can be matched according to the conditions of ships required by the lessees, the budgets of the lessees and the like, if at least one piece of renting demand information of the lessees conforms to the renting demand information of the lessees, the ships provided by the lessees at the moment are considered to be the ships meeting the requirements of the lessees, all the obtained ships meeting the requirements of the lessees are comprehensively sequenced, the sequenced ships are recommended to the lessees as optional ships to be selected by the lessees, and the ships finally selected by the lessees from all the optional ships are target ships.
After all ships meeting the requirements of the lessee are obtained, historical order prices of all the ships can be obtained, prices to be paid by the lessee are estimated according to the historical order prices, and when the lessee is recommended to the lessee, the ships and the corresponding estimated prices are recommended to the lessee together.
In the embodiment of the invention, the matching method can be a KMP algorithm, a simhash algorithm or a text matching algorithm based on deep learning and the like. Similarity calculation is carried out on all the renting demand information of the renters and the renting demand information of all the renters in the database, and the higher the similarity is, the higher the matching degree of the two is proved to be, and the renting demand of the renters can meet the renting demand of the renters. After all matching results are obtained, sorting can be carried out according to the similarity, and optional ships are recommended to lessees; corresponding weights can be set for different renting demand information of the renters according to actual conditions, the recommendation sequence of the optional ship is calculated according to the similarity between each renting demand information and the corresponding renting demand information and the preset weight, and the optional ship is recommended for the renters according to the calculated sequence; and sorting according to the estimated price, and recommending optional ships for the lessees according to the sequence of the estimated price from high to low or from low to high.
After receiving the recommended optional ships, the lessees can select the optional ships according to the actual requirements of the lessees, and finally the selected ships are the target ships. After the lessees finish the selection of the ships, the lessees and the lessees can carry out the ship leasing transaction on line and contract on line to generate a ship leasing contract. And generating an intelligent contract based on key data in the ship leasing contract, such as basic information of a lessor and a lessee, the name of a leased ship, the tonnage, the driving route, the leasing price and the like. An intelligent contract is a computer protocol that aims to propagate, verify or execute contracts in an informational manner. Smart contracts allow trusted transactions to be conducted without third parties, which transactions are traceable and irreversible.
And finally, executing step S3, after the intelligent contract is generated, deploying the intelligent contract to the block chain, and monitoring the ship leasing transaction between the lessor and the lessee based on the intelligent contract.
The blockchain refers to a technical scheme for collectively maintaining a reliable database in a decentralized and distrust-free mode. According to the technical scheme, any plurality of nodes participating in the system calculate and record all information communication data in the system in a period of time to one data block through a cryptographic algorithm, and generate fingerprints of the data block for linking the next data block and checking, and all the participating nodes of the system jointly determine whether the record is true or not. Blockchain is a generic term for a technical solution similar to non-relational databases, and can be implemented by many programming languages and architectures. And the blockchain can also support programmable contracts, naturally suitable for intelligent contracts. In the embodiment of the present invention, the blockchain may be implemented by using a workload Proof (Proof of Work, POW), a rights Proof (Proof of stamp, POS), a stock authorization Proof mechanism (delete Proof of stamp, DPOS), and the like.
The intelligent contract is deployed on the blockchain, namely the intelligent contract is placed on the blockchain in the form of codes based on the binary coding of the intelligent contract, and at the moment, the intelligent contract can be converted into an executable program by utilizing a blockchain network.
After the intelligent contract is deployed to the blockchain, the ship leasing transaction between the lessor and the lessee can be monitored through the intelligent contract. The intelligent contract can contain all information of the lessor and the lessee in the process of the ship leasing transaction, the intelligent contract comprises different stages of the ship leasing transaction, and the intelligent contract can execute the next stage only if the starting requirement of entering the next stage is met. Therefore, different states of the ship leasing transaction can be tracked by tracking different stages of the intelligent contract, and the purpose of monitoring the ship leasing transaction is achieved.
According to the ship leasing method provided by the embodiment of the invention, the ship leasing information is obtained, the optional ship is recommended to the lessee based on the information, the intelligent contract is generated and deployed on the block chain after the lessee signs the contract with the lessee on line, the business handling process of both sides of the ship leasing is simplified, the threshold of both sides of the leasing on the business proficiency is reduced, the leasing transaction line is realized without depending on an intermediary person familiar with the business, the process of the leasing transaction is further simplified, the intelligent contract deployed on the block chain is transparent and traceable but cannot be tampered, the trust problem of both sides of the leasing is solved, the dispute of people such as expense delinquent is reduced, and the labor cost is reduced.
On the basis of the above embodiment, the ship leasing method provided in the embodiment of the present invention, which monitors a ship leasing transaction between the lessor and the lessee based on the intelligent contract, specifically includes:
if the trigger of the effective condition of the intelligent contract is judged and known, entering an automatic execution stage of the ship leasing transaction, and judging whether the end condition of the intelligent contract is triggered in real time;
and if judging that the finishing condition of the intelligent contract is triggered, entering an execution ending stage of the ship leasing transaction.
Specifically, fig. 2 is a schematic diagram of conditions for different stages of triggering an intelligent contract according to an embodiment of the present invention. As shown in fig. 2, if the start condition of the renting ship is triggered, the effective condition of the intelligent contract is triggered, the intelligent contract executes the next stage, and then the automatic execution stage of the ship renting transaction is started; at this stage, the intelligent contract detects whether the condition of the next stage is triggered in real time, if the judgment result is that the ending condition of the intelligent contract is triggered, the ship renting ending condition is triggered, the ending stage of the ship renting transaction is entered at this moment, and the ending stage is automatically executed.
When the lessees and the lessors finish on-line signing of the ship leasing contract, the state of the leasing order is updated to be valid of the ship leasing contract, the ship leasing transaction is started, namely the ship leasing starting condition is triggered, the intelligent contract inquires the valid state of the ship leasing contract, the valid condition is judged to be triggered, the intelligent contract is started to be valid, and the ship leasing transaction enters an automatic execution stage.
At this stage, the intelligent dating real-time inquiry is made whether the ending condition is triggered, namely whether the ship renting ending condition is triggered. The intelligent contract can judge the ship leasing ending condition every a preset time period, namely whether the ship leasing contract is updated to contract ending or not is judged, if the judgment result is that the ship leasing ending condition is triggered, namely the ship leasing contract is in a contract ending state at the moment, the intelligent contract enters the next stage, and the ship leasing transaction enters the ending stage of the transaction. The preset time period may be set according to actual requirements, which is not specifically limited in the embodiment of the present invention.
And in the ending stage of the transaction, the lessee and the lessor automatically trade the tail money, and after the two parties of the transaction end the tail money transaction, the intelligent contract execution is ended.
According to the ship leasing method provided by the embodiment of the invention, different execution stages of the ship leasing are obtained by judging whether the effective condition and the ending condition of the intelligent contract are triggered or not, the ship leasing transaction between a lessor and a lessee is monitored, the purpose of realizing automatic execution of the transaction by using the intelligent contract is achieved, the efficiency of the ship leasing transaction is improved, and the artificial dispute in the ship transaction process is reduced.
On the basis of the foregoing embodiment, the ship leasing method provided in the embodiment of the present invention, which monitors a ship leasing transaction between the lessor and the lessee based on the intelligent contract, further includes:
receiving ship delivery confirmation information of the lessee and sending ship receiving confirmation information to the lessee;
and after receiving the ship receiving confirmation result information fed back by the lessee based on the ship receiving confirmation information, acquiring the position information of the target ship, verifying the position information of the target ship, and determining the effective condition trigger of the intelligent contract if the verification is passed.
Specifically, before monitoring the ship leasing transaction between the lessor and the lessee by using the intelligent contract, whether the lessor and the lessee start the ship leasing transaction or not should be determined, namely whether the two parties of the transaction have delivered and received the ship or not should be confirmed. Before the transaction is started, the position information of the ship needs to be inquired and verified, after the verification is passed, the condition that the start of the ship renting is triggered is proved, and the intelligent contract can be used for monitoring the ship renting transaction.
In the embodiment of the invention, after the lessee selects the target ship, the lessee holding the target ship receives the ship selection notice of the lessee, and sends ship delivery confirmation information to determine that the ship is delivered to the lessee for transaction. After receiving the ship delivery confirmation information of the lessee, the lessee can send ship receiving confirmation information to the lessee, and after receiving the ship receiving confirmation information, the lessee feeds back the ship receiving information and sends the ship receiving confirmation information.
In the embodiment of the invention, the lessees and the lessees can confirm and select the information through the visual window. For the lessor, displaying whether to take the ship or not on a visual window interface, and if the lessor selects yes, sending ship-taking confirmation information; if the lessor selects no, the ship leasing transaction fails, and the lessee side receives the recommendations of other optional ships. For the lessees, displaying whether the lessees are connected or not on a visual window interface, if the lessees select yes, confirming that the ship connection is completed, sending back ship connection information, completing online signing between the lessees and lessees, generating a ship leasing contract and preparing for starting a ship leasing transaction; if the lessee selects no, the ship leasing transaction is closed.
After receiving the feedback of the confirmation ship-receiving request of the lessee, the lessee and the lessee are all completed with confirmation information at the moment, and the ship leasing transaction can be ready to start. Before the transaction begins, the position information of the target ship is acquired, the position information of the target ship is verified, whether the target ship stops at a port specified in the ship leasing contract is determined, if the verification is passed, namely the target ship stops at the port specified in the ship leasing contract, the effective condition of the intelligent contract is triggered, the intelligent contract takes effect, and the next stage is executed.
In the embodiment of the invention, the position information of the target ship can be called from the ship behavior notarization system through the ship behavior notarization interface. The ship behavior notarization system is a system for storing ship real related data, and the ship real related data comprises position information, running tracks, ports of attachment, running time and the like of a ship. The position information of the ship can also be obtained through the GPS positioning of the ship or extracted from other databases storing the related data. After the ship position information is obtained, comparing the ship position information with position information specified in a ship leasing contract, if the distance between the ship position information and the position information is within a preset range, passing the verification, triggering an effective condition of an intelligent contract, and starting the intelligent contract to execute the next stage. If the verification fails, the effective condition of the intelligent contract cannot be triggered, and at the moment, feedback information that the verification fails can be sent out, so that the renting related personnel can conveniently find out the situation in time. The preset range may be set as required, and the present invention is not limited thereto.
According to the ship leasing method provided by the embodiment of the invention, the effective condition of the intelligent contract is triggered through the ship delivery confirmation information of the lessor, the ship receiving confirmation information of the lessee and the verification of the ship position information, so that reliable data verification guarantee is provided for the authenticity of the automatic execution of the intelligent contract, and the rights and interests of both leasing parties are further protected.
On the basis of the above embodiment, the method for renting a ship according to the embodiment of the present invention, which determines whether the ending condition of the intelligent contract is triggered in real time, specifically includes:
judging whether ship returning confirmation information of the lessee is received in real time;
if the taxi returning confirmation information is judged to be received, the taxi returning confirmation information is sent to the lessor;
and after receiving the ship receiving confirmation result information fed back by the lessor based on the ship receiving confirmation information, acquiring the position information of the target ship, verifying the position information of the target ship, and determining the triggering of the ending condition of the intelligent contract if the verification is passed.
Specifically, after the intelligent contract starts to execute the next stage after the intelligent contract takes effect, the intelligent contract inquires in real time whether an ending condition is triggered, that is, whether a ship renting ending condition is triggered, and the ship renting ending indicates that the target ship is used up by the lessee at the moment, so that the target ship can be returned to the specified port. Therefore, whether the rental ship ending condition is triggered can be judged by judging whether the returning ship confirmation information of the lessee and the receiving ship confirmation information of the lessee are received. And if the ship returning confirmation information of the lessee is received, the ship receiving confirmation information can be sent to the lessee to remind the lessee of confirming the ship receiving. After receiving the ship-receiving confirmation information of the lessor, the position information of the target ship is verified, if the verification is passed, the ship leasing contract is updated to be in an end state, the end condition of the intelligent contract is triggered at the moment, the ship leasing transaction is in an ending stage, the two lessors automatically trade the tail, and the intelligent contract is executed and ended.
In the embodiment of the invention, the information sent by the lessee can be received every preset time period, and whether the received information is the ship returning confirmation information of the lessee or not is judged; if the taxi returns the ship confirmation information, the ship receiving confirmation information is sent to the lessee, the lessee is informed that the lessee returns the target ship, and the ship receiving can be carried out. After receiving the ship-receiving confirmation of the lessor, the two parties of the transaction can finish the transaction, and after the verification of the position information of the ship is finished, the ship leasing transaction can be finished.
In the embodiment of the invention, the lessor and the lessee can carry out ship returning confirmation and ship receiving confirmation through the visual window. The position information of the target ship is obtained by the same method as that in the above embodiment, and is not described herein again. After the position information of the target ship is acquired, the position information is compared with a ship returning position specified in a ship leasing contract, if the distance between the position information and the ship returning position is within a preset range, verification is passed, at the moment, the ship leasing contract is updated to a contract ending state, an ending condition of an intelligent contract is triggered, the ship leasing transaction enters an ending stage, and two transaction parties automatically trade a tail payment. The preset range may be set as required, and the present invention is not limited thereto.
According to the ship leasing method provided by the embodiment of the invention, the ending condition of the intelligent contract is triggered through the ship returning confirmation of the lessee, the ship receiving confirmation of the lessee and the verification of the ship position information, so that data guarantee is provided for the ending of the intelligent contract, the leasing process is reduced, the tail payment can be traded automatically, and the artificial expense dispute is reduced.
On the basis of the above embodiment, the ship leasing method provided in the embodiment of the present invention further includes, after receiving the target ship selected by the lessor from the selectable ships and after the lessor signs a contract with the lessee online, the steps of:
acquiring real-time state information of the target ship;
and after receiving the query instruction of the real-time state information of the target ship, displaying the real-time state information.
Specifically, after the lessee selects the target ship, the lessee and the lessee can carry out on-line contract signing to generate a ship leasing contract, and when the ship leasing contract is updated to a contract starting state, the transaction starts to be automatically executed. The lessee starts to use the target ship, and the real-time state information of the target ship can be acquired, so that the acquired real-time state can be displayed after receiving the inquiry command of the real-time state information of the target ship for double transaction.
In the embodiment of the invention, the real-time state information of the target ship can be extracted from the ship notarization system through the ship notarization system interface; and the AIS message sent by the ship can be received, and the real-time state information of the ship is acquired by analyzing the AIS message.
