Fig. 3 is a schematic flow chart of a vehicle sharing method based on blockchain according to an embodiment of the present application. As shown in fig. 3, the method may include the steps of:
Step S101, a vehicle disabling request sent by a target user node is obtained, and second time position information of a shared vehicle is recorded according to the vehicle disabling request.
Specifically, the vehicle stopping request sent by the target user node is obtained, and prompt information is returned to the target user node according to the vehicle stopping request; the prompt information comprises a confirm disabling prompt and a closing the shared vehicle prompt; and when a confirmation response of the target user node to the prompt information is received, controlling the door lock of the sharing vehicle to be closed, and recording the second time position information.
Referring to fig. 2 and fig. 4 together, fig. 4 is a schematic view of a situation where a vehicle is requested to be deactivated according to an embodiment of the present application. As shown in fig. 2, when the target user drives the shared vehicle 30 to the destination, a vehicle deactivation request is sent to the in-vehicle device node 10 using the target user node 20, as shown by an interface 200a of the target user node 20 in fig. 4, clicking an "end car" button in the application software or applet; after receiving the above-mentioned vehicle deactivation request, the vehicle-mounted device node 10 returns a prompt message to the target user node 20, as shown in an interface 200b of the target user node 20 in fig. 4, firstly prompts whether to determine to deactivate the shared vehicle 30, if the target user clicks the "continue to use vehicle" button, the shared vehicle 30 continues to operate, the vehicle-mounted device node 10 continues to time, if the target user clicks the "confirm end" button, the vehicle-mounted device node 10 returns a prompt to close the shared vehicle according to the current closing state of the shared vehicle 30, such as closing a vehicle door, closing a power supply, braking reset, etc., and when the target user determines to close the shared vehicle 30, as shown in an interface 200c of the target user node 20 in fig. 4, clicks the "closed vehicle" button; after receiving the reply, the vehicle-mounted device node 10 controls the door lock of the shared vehicle 30 to be closed, and records second time position information of the shared vehicle, where the second time position information may include: the door lock closing time of the shared vehicle 30, the door lock closing geographical position of the shared vehicle 30, the identity of the shared vehicle 30, the account number of the target user node 20 corresponding to the application or applet, etc.
Step S102, calling a first intelligent contract according to the vehicle disabling request, and acquiring first time position information of the shared vehicle from a blockchain according to the first intelligent contract; the first time location information is information associated with the shared vehicle that is collected when the target user node sends a vehicle use request.
Specifically, after the door lock of the shared vehicle 30 is closed according to the vehicle deactivation request sent by the target user node 20, the vehicle-mounted device node 10 triggers the first intelligent contract to calculate the cost of using the shared vehicle 30 by the target user node 20; the first smart contract obtains a first chunk (i.e., chunk 100 in fig. 2) from the blockchain based on the account number of the target user node 20 corresponding to the application or applet and the identity of the shared vehicle 30, thereby obtaining first time location information in the first chunk.
The first block is a block generated by the vehicle-mounted device node 10 according to the vehicle use request sent by the target user node 20, and is a block associated with the shared vehicle 30 and the target user node 20 and having the maximum block generation time stamp;
step S103, determining a consumption resource order corresponding to the target user node according to the first smart contract, the first time location information and the second time location information.
Specifically, the vehicle-mounted device node invokes the first intelligent contract, calculates the cost of using the shared vehicle by the target user node through the first time position information and the second time position information, namely, determines the consumption resource order.
The working principle of the first smart contract is similar to if-then statement implemented in the program code, and when the preset condition is triggered (e.g. when the on-board device node 10 confirms that the target user node 20 is closing the shared vehicle 30 in fig. 2), the first smart contract executes the corresponding contract term (e.g. when the on-board device node 10 determines the usage fee of the target user node 20 in fig. 2).
Step S104, performing a uplink processing on the consumption resource order, the first time location information, the second time location information, and the function name in the first smart contract.
Specifically, to ensure data security, in order to facilitate tracing the usage situation of the shared vehicle, the vehicle-mounted device node 10 generates a second block to be added to the blockchain (i.e. block 200 in fig. 2) by using the resource consumption order (i.e. the cost of using the shared vehicle by the target user node), the first time location information, the second time location information, and the function name in the first smart contract, then broadcasts the second block to other consensus nodes on the blockchain, and adds the second block to the blockchain when the other consensus nodes successfully verify the second block.
According to the embodiment of the application, the vehicle stopping request sent by the target user node is obtained, and the second time position information of the shared vehicle is recorded according to the vehicle stopping request; invoking a first intelligent contract according to the vehicle disabling request, and acquiring first time position information of the shared vehicle from a blockchain according to the first intelligent contract; the first time position information is information which is acquired by the target user node when the target user node sends a vehicle use request and is associated with the shared vehicle; determining a consumption resource order corresponding to the target user node according to the first intelligent contract, the first time position information and the second time position information; and carrying out uplink processing on the consumption resource order, the first time position information, the second time position information and the function names in the first intelligent contract. As can be seen from the above, when the vehicle deactivation request sent by the target user node is obtained, the vehicle-mounted device node records the second time position information of the shared vehicle, invokes the first intelligent contract to obtain the first time position information of the shared vehicle in the blockchain, determines the consumption resource order of the shared vehicle by the target user node through the first intelligent contract, the first time position information and the second time position information, and performs the uplink processing on the function name, the first time position information, the second time position information and the consumption resource order in the first intelligent contract, so that the consumption resource order of the shared vehicle can be automatically settled and the real shared information of the shared vehicle can be traced.
Fig. 5 is a flow chart of another vehicle sharing method based on blockchain according to an embodiment of the present application. As shown in fig. 5, the method may include the steps of:
Step S201, a vehicle disabling request sent by a target user node is obtained, and second time position information of a shared vehicle is recorded according to the vehicle disabling request.
The specific implementation process of step S201 may refer to the description of step S101 in the embodiment corresponding to fig. 3, and will not be described herein.
Step S202, calling the first intelligent contract according to the vehicle disabling request, and acquiring a first block from a block chain according to the first intelligent contract; the first chunk is a chunk associated with the shared vehicle and the target user node and having a largest chunk generation timestamp.
Specifically, when the door lock of the shared vehicle is closed, a first intelligent contract stored in the vehicle-mounted equipment node is triggered, and the first intelligent contract is used for determining a consumption resource order corresponding to the target user node, namely, the cost of using the shared vehicle, and in order to ensure reliable and safe data, a first block in a block chain is acquired according to the identification of the shared vehicle and the account number of the target user node corresponding to the application software or the applet, wherein the first block comprises first time position information of the shared vehicle.
Step S203 obtains the first time position information of the shared vehicles in the first zone based on the first smart contract.
Specifically, in order to determine the resource consumption order corresponding to the target user node, the time and the geographic position of the target user node for starting the shared vehicle need to be determined, and the time and the geographic position of the target user node for starting the shared vehicle can be determined by acquiring the first time position information of the shared vehicle in the first block.
The first time position information may include a door lock unlocking time of the sharing vehicle, a door lock unlocking geographic position of the sharing vehicle, an identification of the sharing vehicle, an account number of the target user node corresponding to the application program or the applet, and the like.
Step S204, based on the first smart contract, obtaining a first timestamp and a first geographic location from the first time location information, and obtaining a second timestamp and a second geographic location from the second time location information.
Specifically, the first timestamp is the time when the vehicle-mounted equipment node opens the shared vehicle door lock; the first geographic position is a geographic position where the vehicle-mounted equipment node opens a door lock of the shared vehicle; the second time stamp is the time when the vehicle-mounted equipment node closes the shared vehicle door lock; the second geographic location is a geographic location where the vehicle-mounted device node closes the shared vehicle door lock.
Step S205, determining a consumption resource order of the target user node using the shared vehicle according to the first timestamp, the first geographic location, the second timestamp and the second geographic location.
