Background
With the transition of light asset management by numerous enterprises, rental markets (e.g., engineering vehicle rentals) develop rapidly, with very wide space. During the rental period, the renter holds and can use the rental equipment, and the lender has ownership of the rental equipment, but cannot comprehensively grasp information such as the use state of the rental equipment. Therefore, there is a problem in that information between the leasing parties is asymmetric in terms of management use of the leasing equipment during the leasing.
Such information is asymmetrical such that use agreements, loss reimbursements, charging billing, etc. for rental equipment typically employ a relatively coarse management model (e.g., billing by rental time, or equipment damage is maintained by the lender load, etc.). This often results in difficulty in clearly defining the rights and responsibilities when disputes occur during the rental process, which is detrimental to the efficient allocation of resources for the rental market.

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 only exemplary 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 present disclosure. It may be evident, however, that one or more embodiments may be practiced without these specific details. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to 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/or 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 should be noted that the terms used herein should be construed to have meanings consistent with the context of the present specification and should not be construed in an idealized or overly formal manner.
Where a convention analogous to "at least one of A, B and C, etc." is used, in general such a convention should be interpreted in accordance with the meaning of one of skill in the art having generally understood the convention (e.g., "a system having at least one of A, B and C" would include, but not be limited to, systems having 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 formulation similar to at least one of "A, B or C, etc." is used, in general such a formulation should be interpreted in accordance with the ordinary understanding of one skilled in the art (e.g. "a system with at least one of A, B or C" would include but not be limited to systems with 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, there is a series of problems caused by the asymmetry of information existing between the two parties of the rental equipment management and use during the rental period. For example, in the current manner of charging for a unit time length when a rental vehicle is charged in a vehicle rental market, how long the time is used calculates the cost by multiplying the cost per unit time length by the number of unit time lengths. For example, the express industry often needs to rent a large number of forklifts and special transportation vehicles in a busy season, and the construction industry needs engineering vehicles such as external excavators and forklift trucks due to progress problems, but the vehicles do not completely play the same role in the renting period. This may result in a reduced willingness of the renter to rent vehicles.
For another example, when daily renting an engineering vehicle, the renter may run the vehicle all-weather at full load for cost saving to maximize the use value of the vehicle. However, this may accelerate the loss of the vehicle, and the lender's all-weather construction may consume a lot of manpower.
Therefore, how to increase the information symmetry of the renter and the renter in the renting market has important significance for improving the mutual trust of the renter and improving the renting efficiency.
In view of the foregoing, an aspect of an embodiment of the present disclosure provides a method and apparatus for building a blockchain for equipment rental. Another aspect of the disclosed embodiments provides a method and apparatus for equipment rental based on blockchain. According to the embodiments of the present disclosure, information transparency of the renting parties in management and use of the renting equipment during the renting period is effectively improved, mutual trust between the renting parties and the renting parties is improved, and renting efficiency is improved.
The method for constructing the blockchain for equipment renting comprises the steps of firstly obtaining renting contract information, wherein the renting contract information comprises information of a plurality of renting equipment to be rented. And then deploying a node corresponding to each leasing equipment to obtain a plurality of nodes. And then constructing a blockchain based on a plurality of nodes, wherein the node corresponding to each leasing equipment is used for acquiring the use information of the leasing equipment and uploading the use information to the blockchain.
In the equipment renting method and device based on the blockchain according to the embodiments of the present disclosure, the blockchain is built by using the above-mentioned building method. The equipment renting method comprises the steps of firstly obtaining state change information of renting equipment, wherein the state change information is used for representing information of switching of the renting equipment between any two states of M states, and M is an integer larger than 1. The state change information is then sent to a node corresponding to the rental device, such that the state change information is uploaded to the blockchain by the node. The rental equipment is then managed based on the state change information recorded in the blockchain that is generated during rental.
According to various embodiments of the present disclosure, a temporary, private blockchain may be built for a lease contract, wherein a node is then deployed for each lease device in the lease contract and connected into the blockchain. Therefore, the use information of the leasing equipment can be recorded in the blockchain, the recorded use information of the leasing equipment is non-tamper-proof by means of the blockchain, the reliability of the use information of the leasing equipment during leasing can be ensured, and the mutual trust of the leasing parties is improved.
According to embodiments of the present disclosure, the rental device may be, for example, any of a vehicle, a display, a computer, a blower, a motor, a decelerator, or a medical device. The present disclosure is not limited in this regard.
Fig. 1 schematically illustrates an application scenario 100 of blockchain construction and equipment rental according to an embodiment of the present disclosure, wherein the application scenario 100 is illustrated as a vehicle rental scenario.
As shown in fig. 1, in an application scenario 100, for example, a rental contract specifies that 5 vehicles (illustrated as vehicles 101-105 in the figure) are rented for a certain period of time. According to embodiments of the present disclosure, a temporary, private blockchain may be built for the rental contract for recording usage information of vehicles 101-105 during the rental, and the like.
Specifically, one blockchain node may be deployed for 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 building a blockchain, wherein the node 1 has the functions of data storage, intelligent contract deployment, data encryption and decryption, common 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, so as to be deployed in each vehicle. In other embodiments, the node 1 may be deployed outside of the vehicle (e.g., cloud or server or data center), and have a correspondence with each vehicle.
According to the embodiment of the present disclosure, the nodes 1 to which the vehicles 101 to 105 respectively correspond may communicate through a network to construct a blockchain. Thus, during execution of the rental contract, the usage information of each vehicle after the rental of the vehicles 101 to 105 can be recorded by the blockchain. The recorded vehicle use information can be guaranteed to be non-tamperable by means of a cryptography algorithm in the blockchain and a transaction consensus mechanism of the blockchain, and the non-tamperable property of the blockchain and the current lease relation is guaranteed.
According to an embodiment of the present disclosure, each of the vehicles 101 to 105 may also have the equipment rental device 2 according to an embodiment of the present disclosure deployed therein. The equipment rental device 2 may be integrated in the electronic system of the vehicle, for example, together with an On-board self-diagnostic system OBD (abbreviation of On-Board Diagnostics).
The equipment renting device 2 may be configured to execute a blockchain-based equipment renting method according to an embodiment of the present disclosure, and upload a vehicle signal acquired by an on-board self-diagnosis system OBD to a corresponding node 1 after processing the vehicle signal, so as to upload the vehicle signal to a blockchain corresponding to the renting contract through the node 1. In addition, the equipment rental device 2 can manage the vehicle by the use information of the vehicle recorded in the blockchain.
For example, fine-grained billing of rental equipment can be achieved during rental. For example, the flexible charge calculation is performed according to the usage information of each vehicle recorded in the blockchain network to count the usage of each vehicle. For example, the method of mixed charging of idle time unit price and using time unit price, or the method of charging of base unit price and using time unit price. In this way, even if the renter rents redundant vehicles for use, if the vehicles (e.g., vehicle 104 and vehicle 105) are idle and unused during the rental, the remaining useful lives of vehicle 104 and vehicle 105 are not affected after the return. The lease may pay only the fees corresponding to the occupancy values of the vehicles 104 and 105 without additional payment of 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 responsibilities of the renter for carrying out the offending action when the vehicle is damaged, the failure responsibilities of the device for natural use, etc. are divided according to the specific situation.
According to the embodiments of the present disclosure, after the rental contract execution is completed, the data in the node 1 corresponding to each of the vehicles 101 to 105 may be exported and saved, and then the blockchain may be broken up. 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. So that the respective node 1 of vehicles 101-105 may rebuild a new blockchain in accordance with the methods of embodiments of the present disclosure while fulfilling the new rental pool.
It should be noted that fig. 1 illustrates 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 it does not mean that the embodiments of the present disclosure may not be applied to other devices, systems, environments, or scenarios.
Fig. 2 schematically illustrates a flow chart of a method of building a blockchain for equipment rental in accordance with an embodiment of the present disclosure.
As shown in fig. 2, a block chain construction method for equipment rental according to an embodiment of the present disclosure may include operations S210 to S230.
In operation S210, rental contract information including information of a plurality of rental devices that need to be rented 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 blockchain is built based on a plurality of nodes, wherein the node corresponding to each rental device is used to obtain the usage information of the rental device, and upload the usage information to the blockchain.
When the blockchain is built, for example, an initialization event may be recorded in the creation block of the blockchain, the initialization event including rental contract information. The rental contract information may include rental party information, a rental contract number, an initially determined rental period, a rental object, a billing mode, a trouble shooting mode, and the like. And the information of the lease contract is recorded in the creation block, so that the corresponding relation between the block chain and the lease contract can be ensured not to be replaced.
According to other embodiments of the present disclosure, the data in the blockchain may be restored and the blockchain may be disassembled based on user operations after rental ends.
According to embodiments of the present disclosure, a blockchain may be built for a lease contract. Wherein rental equipment rented to fulfill the rental contract is connected into the blockchain system to form nodes of the blockchain. Therefore, the use information of the leasing equipment can be recorded in the blockchain, and the recorded use information of the leasing equipment is non-tamperable by means of the blockchain, so that the reliability of the use information of the leasing equipment during leasing can be ensured to a large extent, and the mutual trust of leasing parties is improved.
Fig. 3 schematically illustrates a flow chart of a blockchain-based device rental method, in accordance with an embodiment of the present disclosure.
As shown in fig. 3, a blockchain-based device rental method according to an embodiment of the present disclosure may include operations S310 to S330. The blockchain is built by executing a lease contract by the nodes corresponding to the lease equipment respectively.
In operation S310, status change information of the rental device is obtained, where the status change information is information characterizing a switch of the rental device between any two states of M states, where M is an integer greater than 1. The duration that the rental device is in a certain state can be calculated based on the status change information of the rental device.
In some embodiments, the M states in which the rental device is in 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, but are not limited to, a use state, an idle state, a fail-over state, a maintenance state, or the like, for example. In some embodiments, the usage state may be further subdivided into a full load operation state, an overload state, or a normal operation state, etc.
According to one embodiment of the present disclosure, the rental equipment can be vehicles (e.g., vehicles 101-105 shown in FIG. 1). In this case, various signals of the vehicle operation acquired by the on-board automatic diagnostic system OBD of the vehicle may be acquired in operation S310, and then state change information of the vehicle may be obtained based on the various signals of the vehicle operation. The on-board automatic diagnostic system OBD can monitor the systems and components such as an engine, a catalytic converter, a particle catcher, 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 the vehicle can be collected. A signal in which the vehicle state change is related may be selected as the state change information in operation S310. It will be appreciated that for other types of rental equipment, various signals of equipment operation may be collected by sensors disposed in the rental equipment.
In operation S320, the state change information is transmitted to a node corresponding to the rental device to upload the state change information to the blockchain through the node.
In operation S330, rental equipment is managed based on state change information generated during rental recorded in the blockchain. Management of rental equipment can include billing management, usage monitoring, damage repair or compensation management for different situations, and the like.
In one embodiment, billing may be based on information recorded in the blockchain based on the status of rental equipment during rental. Specifically, for example, the duration that the rental equipment is in M states during the rental period may be calculated based on state change information generated during the rental period recorded in the blockchain, and the rental fee of the rental equipment may be calculated based on the duration that the rental equipment is in each of the M states during the rental period and the charging unit prices 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 finer granularity charging of the rental equipment can be realized in the period of rental, such as a mode of mixed charging of idle unit price and long unit price in use, or a mode of adding rectangular charging of basic unit price and long unit price in use, and the like.
FIG. 4 schematically illustrates a blockchain-based vehicle rental flow, in accordance with an embodiment of the present disclosure. Fig. 4 illustrates an example application of billing management of leased vehicles using a method according to an embodiment of the present disclosure.
As shown in fig. 4, referring to fig. 1, the node 1 deployed in each vehicle and the set rental device 2 in this embodiment may be implemented as an in-vehicle block module 41 and a vehicle charging module 42, respectively. The on-board block module 41 and the vehicle billing module 42 may be integrated with the OBD on-board self-diagnostic system 43 in a vehicle electronic system for billing management of rented vehicles.
The OBD onboard self-diagnostic system 43 collects various signals of vehicle operation and may then send the collected signals to the onboard billing module 42. The various signals of vehicle operation may include, for example, but are not limited to, a vehicle start signal or a vehicle flameout signal.
