Detailed Description
Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. It should be understood that the description is illustrative only and is not intended to limit the scope of the present disclosure. In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the disclosure. It may be evident, however, that one or more embodiments may be practiced without these specific details. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present disclosure.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The terms "comprises," "comprising," and the like, as used herein, specify the presence of stated features, steps, operations, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, or components.
All terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art unless otherwise defined. It is noted that the terms used herein should be interpreted as having a meaning that is consistent with the context of this specification and should not be interpreted in an idealized or overly formal sense.
Where a convention analogous to "at least one of A, B and C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B and C" would include but not be limited to systems that have a alone, B alone, C alone, a and B together, a and C together, B and C together, and/or A, B, C together, etc.). Where a convention analogous to "A, B or at least one of C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B or C" would include but not be limited to systems that have a alone, B alone, C alone, a and B together, a and C together, B and C together, and/or A, B, C together, etc.).
In the rental market, information existing in management and use of rental equipment between two renters during a rental period is asymmetric, which brings about a series of problems. For example, in the current vehicle rental market, the rental vehicle is charged by a unit time length, and the usage time is calculated by multiplying the unit time length by the unit time length. For example, in the express delivery industry, a large number of forklifts and special transport vehicles need to be rented in a busy season, and in the construction industry, external engineering vehicles such as excavators and forklifts are needed due to the progress problem, but the vehicles do not play the same role completely in the renting period. This may result in a reduced willingness of the rental car from the rental party.
For another example, when a work vehicle is rented on a daily basis, the renter may operate the vehicle at full load all the day to maximize the use value of the vehicle. However, this may accelerate the large wear of the vehicle and the entire day of the construction of the lender may be labor intensive.
Therefore, how to increase the information symmetry of the lender and the lender in the leasing market has important significance for improving the mutual trust of the lender and improving the leasing efficiency.
In view of this, an aspect of the disclosed embodiments provides a method and an apparatus for building a block chain for device leasing. Another aspect of the embodiments of the present disclosure provides a device leasing method and apparatus based on a block chain. According to the embodiments of the disclosure, the information transparency of the two renters in the management and use of the renting equipment during the renting period is effectively improved, the mutual trust between the renter and the renter is improved, and the renting efficiency is improved.
The building method of the block chain for equipment leasing according to the embodiment of the disclosure comprises the steps of firstly obtaining leasing contract information, wherein the leasing contract information comprises information of a plurality of leasing equipment needing to be leased. And then deploying a node corresponding to each leasing device to obtain a plurality of nodes. And then building a block chain based on a plurality of nodes, wherein the node corresponding to each rental device is used for acquiring the use information of the rental device and uploading the use information to the block chain.
According to the equipment leasing method and device based on the block chain in the embodiment of the disclosure, the block chain is constructed by utilizing the construction method. The method for renting the equipment comprises the steps of firstly obtaining state change information of the renting equipment, wherein the state change information is used for representing the information of switching between any two states of the renting equipment in M states, and M is an integer larger than 1. And then sending the state change information to a node corresponding to the leasing equipment so as to upload the state change information to the block chain through the node. The rental device is then managed based on the state change information recorded in the blockchain that was generated during the rental.
According to various embodiments of the present disclosure, a temporary, private blockchain may be established for a lease contract, wherein then a node is deployed for each lease equipment in the lease contract and connected to the blockchain. Therefore, the use information of the leased equipment can be recorded in the block chain, and the recorded use information of the leased equipment can be tamperproof by means of the block chain, so that the credibility of the use information of the leased equipment during the lease period can be ensured, and the mutual trust of two leasers is improved.
According to the embodiment of the disclosure, the rental device can be any one of a vehicle, a display, a computer, a fan, a motor, a decelerator, or a medical device, for example. The present disclosure is not limited thereto.
Fig. 1 schematically illustrates an application scenario 100 of block chain building and device rental according to an embodiment of the present disclosure, wherein the application scenario 100 is exemplified as a vehicle rental scenario.
As shown in FIG. 1, in an application scenario 100, for example, a rental contract promises to rent 5 vehicles (e.g., vehicles 101-105 in the figure) for a certain period of time. According to the embodiment of the disclosure, a temporary and private block chain can be established for the rental contract and used for recording the use information and the like of the vehicles 101 to 105 during the rental period.
Specifically, one blockchain node may be deployed corresponding to each of the vehicles 101-105, such as node 1 deployed in each of the vehicles in FIG. 1. The node 1 is a node capable of establishing a block chain, wherein the node 1 has functions of data storage, intelligent contract deployment, data encryption and decryption, consensus algorithm execution and the like. The data in each node may be saved to a corresponding database. It will be appreciated that the node 1 may be integrated in the electronic system of each vehicle, and thus deployed in each vehicle. In other embodiments, the node 1 may be deployed outside the vehicle (for example, in a cloud or a server or a data center), and has a corresponding relationship with each vehicle.
According to the embodiment of the disclosure, the nodes 1 corresponding to the vehicles 101-105 can communicate through a network to form a block chain. Therefore, in the process of executing the rental contract, the use information of each vehicle after the vehicles 101 to 105 are rented can be recorded through the blockchain. By means of a cryptographic algorithm in the block chain and a transaction consensus mechanism of the block chain, the recorded vehicle use information can be ensured to be non-tamper-proof, and the block chain and the current lease relationship can be ensured to be non-tamper-proof.
According to an embodiment of the disclosure, a device rental apparatus 2 according to an embodiment of the disclosure may also be disposed in each of the vehicles 101-105. The device rental arrangement 2 can be integrated, for example, in an electronic system of the vehicle together with an On-Board Diagnostics system OBD (abbreviation for On-Board Diagnostics).
The device leasing apparatus 2 may be configured to execute the device leasing method based on the block chain according to the embodiment of the present disclosure, and upload the vehicle signal acquired by the on-board self-diagnosis system OBD to the corresponding node 1 after processing, so as to upload the vehicle signal to the block chain corresponding to the leasing contract through the node 1. In addition, the equipment rental apparatus 2 can manage the vehicle by the use information of the vehicle recorded in the block chain.
For example, fine grained billing for rental equipment may be implemented during rental. For example, the usage of each vehicle is counted based on the usage information of each vehicle recorded in the block chain network, and flexible charging calculation is performed. For example, the charging method is a method of charging the idle duration unit price and the usage duration unit price in a mixed manner, or a method of charging the basic unit price plus the usage duration. Thus, even if the lender rents a redundant vehicle for use, the remaining useful life of the vehicles 104 and 105 is not affected if the vehicles (e.g., vehicles 104 and 105) are left unused during the rental period. The lender can pay only the fees corresponding to the occupancy values of the vehicles 104 and 105 without additionally paying the loss values of the vehicles 104 and 105. Therefore, the vehicle charging mode can be more reasonable, and the resource allocation in the leasing process is more optimized.
Or, for example, according to the usage information of each vehicle recorded in the blockchain network, the responsibility generated by the lender for performing default behavior or the responsibility of a fault generated by natural use of equipment when the vehicle is damaged is divided according to specific situations, and the like.
According to the embodiment of the disclosure, after the execution of the rental contract is finished, the data in the nodes 1 corresponding to the vehicles 101 to 105 can be exported and stored, and then the block chain is disassembled. For example, the data stored in each node 1 may be erased after the data in the node 1 corresponding to each of the vehicles 101 to 105 is transferred. Therefore, the nodes 1 corresponding to the vehicles 101-105 can rebuild a new block chain according to the method of the embodiment of the disclosure while fulfilling a new rental combination.
It should be noted that fig. 1 is only an example of an application scenario in which the embodiments of the present disclosure may be applied to help those skilled in the art understand the technical content of the present disclosure, but does not mean that the embodiments of the present disclosure may not be applied to other devices, systems, environments or scenarios.
Fig. 2 schematically shows a flowchart of a building method of a blockchain for device rental according to an embodiment of the present disclosure.
As shown in fig. 2, a building method of a block chain for device rental according to an embodiment of the present disclosure may include operations S210 to S230.
In operation S210, lease contract information including information of a plurality of lease devices to be leased is acquired.
In operation S220, a node is deployed for each rental device, resulting in a plurality of nodes (e.g., node 1 in fig. 1).
In operation S230, a block chain is established based on a plurality of nodes, where a node corresponding to each rental device is used to acquire usage information of the rental device and upload the usage information to the block chain.
When building a block chain, for example, an initialization event may be recorded in a created block of the block chain, where the initialization event includes lease contract information. The lease contract information may include leasing party information, lease contract number, initially determined lease duration, lease objective, billing method, failure responsibility agreement method, and the like. And recording the lease contract information in the founding block, so that the corresponding relation between the block chain and the lease contract is not replaced.
According to other embodiments of the disclosure, the data in the blockchain can be unloaded and the blockchain can be disassembled based on user operations after the leasing is finished.
According to embodiments of the present disclosure, a blockchain may be established for a lease contract. And connecting the leasing equipment leased for fulfilling the leasing contract into the blockchain system to form the nodes of the blockchain. Therefore, the use information of the rental equipment can be recorded in the block chain, and the non-tampering property of the recorded use information of the rental equipment is realized by means of the block chain, so that the credibility of the use information of the rental equipment during the rental period can be ensured to a greater extent, and the mutual trust of two renters is improved.
Fig. 3 schematically shows a flowchart of a device leasing method based on a block chain according to an embodiment of the present disclosure.
As shown in fig. 3, a device leasing method based on a block chain according to an embodiment of the present disclosure may include operations S310 to S330. The block chain is built by the nodes corresponding to the leasing equipment in a leasing contract.
In operation S310, state change information of the rental device is obtained, where the state change information is used to represent switching of the rental device between any two states of M states, where M is an integer greater than 1. The time length of the rental equipment in a certain state can be calculated based on the state change information of the rental equipment.
In some embodiments, the M states in which the rental device is located include at least a use state and an idle state. In other embodiments, the M states in which the rental device is located may include, for example and without limitation, a use state, an idle state, a downtime state, a maintenance state, or the like. In some embodiments, the usage state may be further subdivided into a full-load operation state, an overload state, a normal operation state, or the like.
According to one embodiment of the present disclosure, the rental device can be a vehicle (e.g., vehicles 101-105 shown in FIG. 1). In this case, in operation S310, various signals of the vehicle operation collected by the on-board automatic diagnostic system OBD of the vehicle may be acquired, and then the state change information of the vehicle may be obtained based on the various signals of the vehicle operation. The OBD can monitor systems and components such as an engine, a catalytic converter, a particle trap, an oxygen sensor, an emission control system, a fuel system, an EGR (Exhaust Gas recirculation) system and the like in real time, so that various signals in the running process of a vehicle can be acquired. In operation S310, a signal related to a change in the state of the vehicle may be selected as the state change information. It is understood that for other types of rental devices, various signals of the operation of the device can be collected by sensors provided in the rental device.
In operation S320, the state change information is transmitted to a node corresponding to the rental equipment to upload the state change information to the block chain through the node.
In operation S330, rental equipment is managed based on state change information generated during rental recorded in the block chain. Management of rental equipment may include billing management, usage monitoring, damage repair or compensation management for different situations, and the like.
In one embodiment, billing may be based on the information recorded in the blockchain, depending on the state of the rental device during the rental period. Specifically, for example, the duration that the rental devices are in M states during rental can be calculated based on the state change information generated during rental recorded in the block chain, and the rental fee of the rental device can be calculated based on the duration that the rental device is in each of the M states during rental and the billing unit price corresponding to the M states.
According to the embodiment of the disclosure, different charging unit prices can be set for different states of the rental equipment, so that charging with finer granularity can be realized for the rental equipment in the rental period, for example, charging in a mode of mixing the idle time unit price and the use time unit price, or charging in a mode of adding the basic unit price and the use time length, and the like.
Fig. 4 schematically illustrates a block chain based vehicle rental flow according to an embodiment of the disclosure. FIG. 4 illustrates an example application of billing management for rented vehicles applying a method according to an embodiment of the present disclosure.
As shown in fig. 4, referring to fig. 1, the node 1 disposed in each vehicle and the rental apparatus 2 disposed in each vehicle in this embodiment may be implemented as a vehicle-mounted block module 41 and a vehicle billing module 42, respectively. The vehicle-mounted block module 41 and the vehicle billing module 42 can be integrated with the OBD vehicle-mounted self-diagnosis system 43 in the vehicle electronic system for billing management of rented vehicles.
The OBD on-board self-diagnostic system 43 collects various signals of the vehicle operation and may then send the collected signals to the on-board billing module 42.
