The charging system of the present invention is not limited to the blockchain system and framework, and other blockchain systems and frameworks may be adopted in different embodiments of the present invention.
The charging system applied to the invention, a specific implementation of a charging method based on a block chain and an intelligent networked automobile, is shown in fig. 1, and is described in the following steps:
s100, after the vehicle enters a charging area, adding a block chain where a charging system is located, finding the vehicle near the vehicle in the charging area through an intelligent networking automobile technology, simultaneously finding the vehicle near the vehicle, wherein the vehicle and the vehicle near the vehicle are both intelligent networking automobiles;
in this embodiment, one way that the vehicle can find a nearby vehicle using the smart internet technology is to use the V2V communication of the internet of vehicles. For the Internet of vehicles of C-V2X (Cellular V2X) standard series, vehicles are communicated with each other in a terminal direct connection mode (PC5) to find nearby vehicles capable of communicating with the vehicles and acquire vehicle information. Further, for the vehicle networking conforming to the IEEE802.11p and 1609 standard series, the vehicle sends WSA (Wireless sensor network Service advertisement) to acquire the response of the nearby communication-capable vehicle. The sender can control the sending power of the V2V communication, thereby controlling the communication range, and can obtain RSSI (Received Signal Strength Indication), so that the vehicle can obtain the relative position data between the vehicles which carry out V2V communication through the vehicle networking communication.
In this embodiment, another way of finding nearby vehicles by using the intelligent internet automobile technology is to obtain and intelligently identify information of nearby vehicles by using vehicle-mounted environment sensing devices such as a vision sensor and a laser radar, and meanwhile obtain relative position data of the nearby vehicles.
When the charging method of the embodiment is applied to the roadside device in the charging system, the roadside device finds a nearby vehicle through V2I communication and the environmental perception sensor, and is also perceived by the nearby vehicle, and in this step, the roles of the roadside device and the vehicle are the same, but the position of the roadside device is fixed in the charging area.
S200, conducting block chain transaction between any vehicle in the charging area and any vehicle nearby according to a preset time interval, generating corresponding transaction information, uploading the transaction information to a block chain in a preset format, and forming block chain consensus;
in the embodiment, nearby vehicles are identified through the intelligent networking automobile technology, only the nearby vehicles can trade between every two vehicles, and the trade information uploaded to the block chain comprises the information of the vehicles of the two parties, the position information of the two parties and the trade time.
In this embodiment, when the charging method of this embodiment is applied to the road side device in the charging system, the road side device and the nearby vehicle perform block chain transaction between two vehicles, and in this step, the road side device and the vehicle have the same role, except that the position of the road side device is fixed in the charging area.
In this embodiment, in a mode of blockchain transaction between vehicles, the vehicles automatically generate virtual assets at certain intervals, the virtual assets have different specifications and characteristics, are associated with the characteristics of the vehicles, and have uniqueness, the virtual assets can only be mutually transferred between nearby vehicles, and the transfer action of the assets is the transaction.
The blockchain records the transaction situation, if the vehicle a initiates a transaction to the vehicle B, the transaction information uploaded to the blockchain is as shown in the following table:
the transaction information in the table is provided by the vehicle A and the vehicle B respectively, if the data provided by the two parties are true and accurate, the items 4 and 5 of the transaction information in the table are consistent with the items 6 and 7, otherwise, the transaction information is considered to have contradiction.
In this embodiment, after all transactions are sent to the blockchain system, the transactions are evaluated by the blockchain consensus mechanism after the consensus service agrees with the transactions. The selected block chain framework should support the pluggable consensus algorithm, so that the consensus algorithm is convenient to select and design.
The consensus algorithm in this embodiment is implemented as follows: the vehicle A initiates a transaction to the vehicle B, namely the vehicle A transfers the virtual assets to the vehicle B, and the vehicle submits the transaction information to the blockchain system; if the data of the transaction information is not contradictory and is endorsed by the transaction exchange of the nearby vehicle, recording the data into the block chain; if one of the nodes A and B is a non-honest node, contradiction exists between the transaction information, and meanwhile contradiction is formed between the transaction information and the transaction information uploaded by other nodes; in the case of contradiction between transaction information between A and B, if A obtains endorsements of more nodes in the block chain relative to B, namely successful transactions are more, the information submitted by A is considered to be credible, otherwise, the information submitted by B is considered to be credible. The consensus algorithm in the implementation can select and adjust the trust weight of the specific node in the consensus algorithm, and the characteristic node can be a specific vehicle or road side equipment.
The implementation also classifies the transaction types into two types of charging transaction and credit rating transaction, the charging transaction is defined only if the data of the transaction information has no contradiction, and the system carries out real-time fee deduction according to the information of the charging transaction; when the data of the transaction are contradictory, the data are not utilized to carry out real-time fee deduction, the system carries out credit rating evaluation on both sides of the transaction according to whether block chain consensus is obtained, and the charging system can carry out further charging system design according to the credit rating formed by the data on the chain.
In conclusion, the key point of the step is that the mutual transaction information uploaded by the vehicles is cross verified by using a consensus algorithm, and the mutual transaction information is used as the basis for charging. The consensus algorithm is based on the principle that most of nodes on the blockchain belong to honest nodes, cross verification is carried out, transactions provided by non-honest nodes are eliminated, consensus is formed, the transaction information based on the consensus is recorded in the blockchain, and all nodes in the blockchain system keep consistency and unique certainty; the consensus algorithm is a core technology of a block chain, different situations exist in practical application, and the consensus algorithm needs to be flexibly designed and adjusted according to practical situations to realize cross validation.
S300, when the time that any vehicle in the charging area stays in or runs in the charging area reaches the preset time or the vehicle is driven away from the charging area, triggering an intelligent contract, and charging the any vehicle by an operation management party in the charging area.
In this embodiment, when the vehicle leaves the charging area, the intelligent contract is triggered, the position and the corresponding time information of the vehicle are obtained according to the vehicle-to-vehicle transaction information included in the block chain, the vehicle is reduced or exempted according to the vehicle-to-vehicle transaction execution condition, and the operation manager performs the charging transaction for the vehicle.
An intelligent contract is a set of commitments defined in digital form, including protocols on which contract participants can execute these commitments, blockchains being a good platform for executing intelligent contracts. The operating logic of the intelligent contract is shown in fig. 2. The implementation mode of charging in the intelligent contract comprises the following steps: the code of the intelligent contract is a part of a block chain in the charging system, once the vehicle stays in a charging area for a preset time or the vehicle is driven out of the charging area, the intelligent contract is triggered, the vehicle transaction information contained in the block chain is read by the intelligent contract to obtain the charging information of the corresponding vehicle, and the charging information comprises the information of the vehicle, the position information of the vehicle and the time information of the vehicle in the charging area; the charging rules such as the rate and the like contained in the intelligent contract are going to the center and are tamper-proof; meanwhile, in order to encourage the vehicle to generate vehicle-to-vehicle transaction information, the intelligent contract can also contain a fee deduction rule, and fee deduction can be carried out according to the number and frequency of vehicle-to-vehicle effective transactions executed by the vehicle. After the intelligent contract is executed, the execution result is permanently recorded on the blockchain after verification.
