Description
Technical Field
The invention belongs to the technical field of road charging or congestion charging devices for vehicles and vehicle owners, and particularly relates to a block chain-based fleet ETC payment information processing system and method.
Background
Currently, the current state of the art commonly used in the industry is such that:
ETC is an electronic automatic toll collection system for highways, bridges and tunnels which is being developed and popularized in an international effort. The technology has a long development history abroad, and electronic charging systems in a plurality of countries and regions such as the United states, Europe and the like are locally networked and gradually form scale benefits. The road networking charging mode mainly based on the manual charging mode is undoubtedly influenced by the trend of using IC cards and magnetic cards as media in China.
The present ETC is used in a way that the vehicle-mounted electronic tag arranged on the windshield of the vehicle and the microwave antenna on the ETC lane of the toll station are in microwave special short-range communication, and a computer networking technology and a bank are utilized to carry out background settlement processing, so that the purpose that the vehicle can pay the toll of the road and the bridge without parking through the toll station of the road and the bridge is achieved. By 10 months in 2018, the utilization rate of ETC in most provinces of China is over half, and some provinces are less than three.
The block chain is a new popular technology in recent years, is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like, has the characteristics of decentralization, openness, independence, safety, anonymity and the like, and has a good application value in the payment field.
With the development of the car networking technology, the connection between cars and vehicles on the expressway is closer and closer, a trend of forming a fleet of cars between the cars is provided, and a trend of forming a safe fleet of cars in the car networking is provided by combining characteristics such as non-tampering of a block chain and the like with a cryptography method, so that the highway payment of the fleet of cars under the block chain scene is an important research direction.
The prior art patent application numbers are: 201810758361.0 discloses configuring a unique identification code in a vehicle and installing a vehicle identification device for quick identification, wherein the identification code is used as identification information added into a block chain for creating a virtual account, and city ETC and highway ETC are combined to be paid by virtual currency in a global range, thereby realizing universal use and reducing management cost. User information confidentiality and feedback information mining are achieved through an evaluation system and an intelligent contract, and various services of the ETC are supervised and evaluated. And a unified clearing module is used, so that the safety of capital is guaranteed. The effect that this patent brought has combined the non-repudiation's of block chain transaction characteristic, has established a payment system of comparatively unified safety, has brought the improvement for ETC payment information processing system at present stage.
With the development of the car networking technology, the connection between cars on a highway is more and more close, the cars on the highway form a fleet, and the team traveling is the trend of the modern society. Meanwhile, vehicles run on the highway by the aid of the existing communication means, vehicle teams can conveniently and uniformly run, and resource allocation is optimized. Although the prior patent uses the blockchain for highway payment scenes, the prior patent is only suitable for charging of single vehicles without stopping the vehicles, and has limitations in the scene of formation of fleet common driving among the vehicles. In modern society, vehicles are not isolated individuals but are closely connected with each other when the vehicles run, and more vehicles form a fleet to run uniformly and dispatch together, so that resources are utilized more reasonably.
Because the vehicles are uniformly dispatched by the head vehicle, in the process that the fleet collectively passes through the ETC channel, the expenses of all vehicles in the fleet are uniformly paid by the head vehicle, all tail vehicles transfer to the head vehicle, but because the vehicles are temporarily grouped together and are not trusted, the vehicles can possibly have the condition of payment repudiation. Therefore, the patent is not suitable for the condition of unified payment in the driving process of the expressway motorcade, the first vehicle replaces the untrustworthy motorcade member to pay, but the repudiation payment problem of the motorcade member is not solved.
In summary, the problems of the prior art are as follows:
the existing ETC payment mode has various defects; the existing technology for paying by using a block chain is only suitable for charging of single vehicles without stopping a vehicle, the limitation is realized under the scene that a fleet of vehicles jointly runs, the fees of all vehicles in the fleet of vehicles are uniformly paid by a head vehicle, all tail vehicles transfer accounts to the head vehicle, the vehicles are temporarily grouped together without mutual trust, and the vehicles can be subject to the condition of payment.
The difficulty of solving the technical problems is as follows: the first car replaces the trailer to pay ETC expense in the motorcade, and the trailer needs to return this ETC expense for the first car after treating the stroke, and has the problem of mutual distrust between first car and the trailer: the distrust head car of the tail car can replace oneself to pay fees, and the distrust head car of the head car can return ETC fees to oneself. To implement such a solution, the team and payment records must be efficiently kept. Data stored by the centralized server can be easily modified, so a decentralised trusted data storage technology must be introduced, which needs to support monetary transactions. The block chain technique can solve the above problems.
The significance of solving the technical problems is as follows: all vehicles in a fleet pass through ETC together, and in order to reduce the time consumed by ETC fee deduction, the scheme adopted is as follows: the head car replaces the tail car to pay ETC cost, and the tail car returns the cost that should pay for the head car after the journey is finished. The problem that the head car and the tail car are not trusted with each other in the process can be solved by the block chain technology. After the purpose of trust removal is achieved, a plurality of vehicles can safely build the fleet, and the other vehicles do not need to worry about the attack damage of the other vehicles to the vehicles, because all transaction payment records in the fleet can be permanently recorded on the block chain, the records can be used as payment certificates in the later period, and the repudiation is prevented.

If the blockchain system detects that the license plate number is not registered, the motorcade ID exists and the tag is not used, the public key of the head car of the motorcade is searched by using the motorcade ID, the public key is used for verifying the digital signature of the tag, the system adds the tail car into the motorcade after the verification is passed, and otherwise, the system refuses to register the motorcade.
2. Off-team: and applying for exiting the motorcade from the ETC system block chain by the tail vehicle, marking the tail vehicle as an off-team state by the system, and then requesting the head vehicle of any motorcade to generate a label for the head vehicle to re-register to enter the motorcade. After the head vehicle applies for exiting the motorcade, the motorcade to which the head vehicle belongs does not exist any more, and all the motorcade members recover the off-team state.
ETC payment: the members of the motorcade are arranged in front and back longitudinal lines and drive to the ETC toll station, and when the toll station identifies the information of the first vehicle, the motorcade can be detected to pass through the toll station, so that the subsequent vehicles of the motorcade can pass through the ETC toll station at one time without stopping in sequence midway. After all vehicles of the fleet pass, the ETC toll station initiates a transaction request in the block chain network, and an intelligent contract is required to process a head vehicle account of the fleet. And the intelligent contract deducts the account of the head vehicle according to the transaction request, and synchronizes the processed account information to each node of the block chain of the ETC system. The intelligent contracts are deployed to run on the blockchain for processing transactions. The tail car pays corresponding fee to the head car on line or off line, and the repayment record is recorded in the chain after being confirmed by both parties.
4. A clearing module: the intelligent contract issues virtual currency, and the block chain account of the vehicle stores the corresponding virtual currency in the intelligent contract, so that the block chain account can be used for realizing exchange rate conversion with real currency. Each node of the vehicle account can initiate a request to the intelligent contract to realize the recharge and withdrawal of the virtual currency.
ETC system block chain: all vehicles and ETC toll stations are nodes in a block chain of the ETC system, and a system intelligent contract runs. Intelligent contracts handle requests for registration, dequeuing, payment and clearing. Each node can inquire all operation records on the block chain, and the denial can be prevented.
The technical solution of the present invention is further described with reference to the following specific examples.
The scheme provided by the invention enables a plurality of vehicles in a fleet to pass through the ETC at one time. Now, according to the data in the actual scene, the platoon according to the scheme of the invention passes through the ETC together and the single vehicle passes through the ETC sequentially in the traditional scheme to be compared.
According to the highway ETC standard, a vehicle should comply with the rules of vehicle speed v and distance Dv between the two vehicles when passing through the ETC. Suppose that m cars constitute a fleet, and the distance between the cars in the fleet is Dp. For n cars with an average length l, the time tploton required for a single car to pass the ETC after establishing the fleet is compared with the time Tvehicle required for a single car to pass the ETC:
according to the standard parameters of ETC, let v be 20km/h, Dv be 10m, Dp be 1m, and l be 4m, and let m be 5 vehicle groups to build a fleet. The results of the experiment are shown in figure 3 for different n. As can be seen from fig. 3, the time taken for a single vehicle to pass through the ETC together after the vehicle is established into a fleet sequentially through the ETC and a plurality of vehicle groups is linearly increased along with the increase of the number of vehicles, which is consistent with the calculation result of the formula. When the number of vehicles is the same, it is clear that the fleet solution of the present invention consumes less time. As the number of vehicles increases, the time interval between the two lines becomes larger. It follows that our scheme saves the time overhead of ETC payments on highways.
It should be noted that the embodiments of the present invention can be realized by hardware, software, or a combination of software and hardware.
