Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Interpretation of terms
Intelligent contract: for a piece of automatically executed code on a blockchain, smart contracts allow trusted transactions to be conducted without third parties, which transactions are traceable and irreversible.
A consensus mechanism: the verification and confirmation of the transaction are completed in a short time through the voting of the special nodes; if several nodes with irrelevant interests can achieve consensus on a transaction, the whole network can be considered to achieve consensus on the node.
Crowdsourcing: is the practice of a company or organization to outsource work tasks, performed by employees in the past, to unspecified (and often large) public volunteers in a free-voluntary fashion.
In order to measure the vehicle high-speed road mileage more accurately and avoid the high-speed road malicious fee evasion behavior, the invention provides a crowd-sourced vehicle position confirmation mechanism, which confirms the real position of the vehicle through data packets sent by vehicle equipment, road basic equipment and a user, thereby deducing the high-speed road mileage of the vehicle. In the real world, a behavior that a user maliciously sends a false message may exist, at the moment, the block chain technology can well solve the trust problem, a consensus mechanism can be utilized to effectively identify a malicious node, and the influence of the malicious behavior on the highway charging system is reduced.
Example one
The embodiment provides a block chain-based high-speed charging system, which is used for solving the problems of low charging efficiency of an expressway and fee evasion behavior of the expressway. The system comprises modules for user registration, journey reporting, journey checking, payment execution, policy incentive and the like. The system can estimate the high-speed road running expense according to the vehicle information and the distance information reported by the user, further determine the high-speed running mileage of the vehicle according to the information sent by the road basic equipment and other vehicles, calculate the actual expense and finally carry out payment on a block chain platform.
As shown in fig. 1, the system architecture proposed by the present embodiment includes an authentication center, a roadside unit, a server, a vehicle device, a user intelligent device, a roadside information collection device, and the like. The authentication center provides identity management and verifies the real identity of the nodes in the block chain, and the main functions include certificate generation, signature and certificate revocation, but the authentication center does not participate in block chain consensus as a node. The roadside unit is used as an important node in the block chain network, can acquire information uploaded by the vehicle equipment, the user intelligent equipment and the roadside information acquisition equipment, and confirms the identity of the vehicle through the information. Each vehicle has a unique identity, namely a license plate number, the license plates of the surrounding vehicles can be captured by roadside information acquisition equipment among the vehicles, the license plates are identified by an image identification algorithm, and then the license plates are written into a block chain account book. The user can also participate in the vehicle journey report by using the user intelligent equipment, and the incentive policy is utilized to provide rewards for the contributing user.
In the embodiment, an expressway entrance and an expressway intersection are selected as monitoring points, the GPS coordinate of each monitoring point is measured, a form of longitude and latitude is adopted, when the error between the GPS coordinate of a certain vehicle or certain user intelligent equipment and the GPS coordinate of the certain monitoring point is smaller than a certain threshold value, the vehicle equipment or the user intelligent equipment can obtain the opportunity of reporting a journey, and the license plate number, the GPS coordinate, the time and the user identity information are used as a transaction and written into a block chain account book. In addition, the roadside information acquisition equipment with the camera shooting function can take a snapshot at certain intervals (usually several seconds, the time length is set according to the needs), and can report the vehicle travel information.
The embodiment sets a status bit for each registered vehicle to identify whether the vehicle is driving on the highway. When the state is 1, the vehicle is indicated to be running on the highway; when the state is 0, it indicates that the vehicle has not driven into the high speed or has driven out of the high speed. When a certain vehicle enters the highway, the status bit is changed from 0 to 1. At the moment, the intelligent contract is triggered to start charging, and real-time charging is carried out according to the travel information sent by the reporter. When a certain vehicle drives out of the highway, the status bit of the vehicle is changed from 1 to 0, and at the moment, the intelligent contract is triggered to start paying, and the driving cost of the highway is pushed to the vehicle.
As shown in fig. 2, during the calculation of the high-speed mileage of the vehicle, the real-time location of the vehicle is determined according to the travel information (license plate number, GPS location information, report time, and reporter identity), and then the road segment of the highway network is matched according to the GPS location information, and after the matching is successful, the mileage of the road segment is counted as the driving mileage of the vehicle. The actual high-speed mileage of the vehicle can be obtained finally.
In the trip verification phase, the present embodiment proposes a vehicle position confirmation mechanism based on crowdsourcing, and one of the requirements of the proposed solution is the support of heterogeneous data sources, including vehicle devices and roadside information collection devices, and personnel using various reporting applications. Support for various data sources is critical because it increases the amount and scope of data collected, supports multiple data sources can provide contextual data, and allows the system to be extended to different types and levels of sensors. The collected data can be used for vehicle position validation and iterative source reputation evaluation. A schematic diagram of a crowd-sourced based vehicle localization mechanism and source reputation evaluation is shown in fig. 3.
The main objective of this embodiment is to design a crowd-sourced vehicle locating system that can identify the true location of the vehicle from the vehicle devices, roadside information collection devices, and user generated reports, while protecting the privacy of the user. Once the vehicle starts the highway trip, the system takes the license plate number as the vehicle identification code so as to track the high-speed trip of the user. Other vehicles or pedestrians cannot know the real identity of the owner of the vehicle associated with the license plate number in the blockchain network, so that the personal privacy of the user can be protected. The vehicles are detected at each intersection before the journey begins to the end, and the detected data must be open and auditable so that they can be reused in other systems. Since different sensing capabilities depend on the source type, the goal of this embodiment is to keep data requirements low, so a simplified data model is designed that supports event reporting from vehicles, infrastructure, and users via their own smartphones. All reports must contain the necessary data such as time stamps, license plate numbers, vehicle locations and data source identification.
The timestamp is the current time of the system when the data is reported in the driving process. The location data is expected to exist as latitude and longitude value pairs. Depending on the source of the report, different positioning accuracies are desired and allowed. Generally, the position of the roadside information collection device is well-defined, and the vehicle and the user's smart phone report that their positions have certain errors. Therefore, the geographical position data of the roadside information collection devices is more reliable.
Due to the openness of the blockchain network, anyone can join the network, and therefore, a false data message may be maliciously issued by a user. And a plurality of roadside units with different safety levels are connected with vehicle equipment, so that malicious attacks can be caused, and the roadside units become unreliable data message publishers, which brings difficulty for evaluating vehicle travel routes. Therefore, a credit evaluation mechanism is introduced, an initial credit value is set for each device and user in the blockchain network, and the credit value is updated according to the performance of the device and user, so that the influence caused by malicious users and attacked unreliable devices is reduced, and the robustness of the system is improved.
Because the ETC charging system has many drawbacks, the embodiment provides an expressway charging mechanism based on an intelligent contract. The payer in the intelligent contract is a registered vehicle, and the payee is an expressway operator. After the expressway journey is completed, the cost is calculated according to the actual driving mileage and is pushed to the payer, the payer establishes a transaction through the blockchain client after confirming the bill, and finally the transaction is sent to the blockchain network. Upon receipt of the transaction, the blockchain network verifies the transaction and writes the legitimate transaction into the global ledger, thus ensuring that the payer successfully pays the road toll and the payee verifies the receipt. The contract is named as an intelligent contract for paying the highway fees, realizes the purpose of setting up a charging standard according to the type of the vehicle, calculates the highway fees in real time, and executes the payment when the vehicle drives out at a high speed. The algorithm flow chart of the intelligent contract for paying the highway toll is shown in FIG. 4:
in the proposed payment mechanism, payment is effected by a blockchain transaction. Thus, payment execution is actually a transaction process that validates and writes to the global ledger. Payment is accounted for once the corresponding transaction is recorded on the global ledger. The payer then checks the global ledger and sends the relevant transaction ID to the payee. If the account and the amount of money of one transaction are accurately identified, the payment process is completed.
The embodiment provides a vehicle positioning mechanism based on crowdsourcing, the real position of a vehicle is found in a crowdsourcing mode, the high-speed driving mileage of the vehicle is calculated, a block chain technology is combined to identify a malicious node, the influence of malicious behaviors on the charging system is reduced, and the robustness and the reliability of the charging system are improved.
