Detailed Description
In order to more clearly explain the overall concept of the present application, the following detailed description is given by way of example in conjunction with the accompanying drawings.
The embodiment of the application discloses a second-hand modified vehicle condition recording method based on a block chain, as shown in fig. 1, comprising the following steps:
In this embodiment of the application, generating each node corresponding to the block chain for recording the second-hand modified vehicle includes: automobile manufacturers, automobile distributors, automobile aftermarket suppliers, automobile repair shops, and insurance companies. The second-hand refitting car buying and selling process relates to a delivery link, a refitting link and a maintenance link. The automobile manufacturer and the automobile seller correspond to a factory leaving link, the automobile accessory maker and the automobile maintenance factory correspond to a refitting link, and the automobile accessory maker, the automobile maintenance factory and the insurance company correspond to an automobile maintenance link. The block chain has the characteristic of distributed accounting, data generated by each node can be synchronized to other nodes, and data tampering of a single node cannot actually take effect, so that the reliability of recording the data on the block chain of the second-hand vehicle is ensured.
And 102, receiving basic information of the vehicle, accident information of the vehicle and refitting information of the vehicle from each node.
In the embodiment of the present application, the vehicle basic information includes: one or more of vehicle delivery date, frame number, engine number, energy consumption, service life information, and parts replacement information. Vehicle condition information, including: one or more of time of occurrence of the accident, accident level, accident type, and wear information of the car in the accident.
And 103, writing the basic information of the vehicle, the accident information of the vehicle and the refitting information of the vehicle into the block.
In the embodiment of the application, the authenticity of the data is ensured by writing the basic information of the vehicle, the accident information of the vehicle and the refitting information of the vehicle into the block, and the data can be ensured to be seen by consumers in each link. And simultaneously carrying out data support for the first intelligent contract.
However, with the development of technology, many new concepts are emerging in the automobile field, which are considered as new basic information of vehicles, for example, electric automobiles increase power consumption, charging time, battery capacity, and the like compared to conventional automobiles. The new basic vehicle information brings new vehicle accident information and new vehicle refit information at the same time, which means that the data category on the block chain needs to be updated in real time to ensure the benefit of the user. In order to solve the above-described problems, in the embodiment of the present application, each node detects whether there is one or more of new vehicle basic information, new vehicle accident information, and new vehicle modification information. The respective node initiates a request to upgrade the first intelligent contract when one or more of new vehicle base information, new vehicle accident information, and new vehicle retrofit information exists.
The real-time data updating is guaranteed to better maintain the right of knowledge of the consumer, and meanwhile, the consumer can be helped to evaluate the vehicle, so that the problem that the modified vehicle is not easy to evaluate is solved. Therefore, in the embodiment of the application, a second intelligent contract is arranged on each node corresponding to the blockchain, wherein the triggering condition of the second intelligent contract receives a vehicle evaluation price request sent by any one of the second party and the second party of the modified vehicle transaction. And after the triggering condition of the second intelligent contract is triggered, determining the price of the second-hand modified vehicle according to the basic information and the accident information of the vehicle in the corresponding block. It can be understood that the technical scheme is that the vehicle basic information, the vehicle accident information and the vehicle refitting information can be updated in real time.
In determining the price of a second-hand refitted vehicle, the most difficult to evaluate is the refitted part. Retrofitting is highly purposeful and therefore may be done at the expense of one other property, where valuation requires comprehensive consideration. Meanwhile, refitting is generally a little-to-many behavior, so that a conventional method is not suitable for evaluating the value of the refitted vehicle. Therefore, in the embodiment of the application, after the triggering condition of the second intelligent contract is triggered, the price of the second-hand modified vehicle is corrected according to the group information of the vehicle friends and the group vehicle condition scoring information. The vehicle retrofit information includes: the group information of the vehicle friends and the group vehicle condition grading information. It should be noted that the vehicle-friend group is a small group formed by some vehicle hobbys. In small groups, the preferred part type, part price and the objective sought by each person are essentially the same. The prices assessed in the conventional manner are therefore revised with the help of the average price of the small group of modified cars.
And step 104, acquiring basic information and accident information of the vehicle from the corresponding blocks.
And 105, sending the basic information of the vehicle, the accident information of the vehicle and the refitting information of the vehicle to a receiver of the second-hand refitted vehicle.
However, with the development of technology, concepts related to automobiles are more and more abundant, resulting in increasing information, for example, future automobiles may add intelligence, power consumption, etc., and if the information is presented to consumers one by one, it is not beneficial for consumers to quickly understand and evaluate products. Therefore, in the embodiment of the present application, when querying the vehicle information, the consumer may first send a vehicle information query message to the server, where the vehicle information query message includes: the system comprises a preset vehicle identification and a vehicle information identification. The preset vehicle identification represents a corresponding vehicle, and the vehicle information identification is an information category which is interested by consumers. The server determines a target block according to the vehicle identification, wherein the target block is a block corresponding to the vehicle identification and having the shortest creation time, and because each block chain contains all information of the previous block, the query time is shortened by determining the target block, and the timeliness of the information is ensured. And finally, the server returns a corresponding vehicle information query message according to the vehicle information identifier.
In addition, the consumer usually pays attention to the price of the second-hand modified vehicle, and in the embodiment of the present application, the consumer may send a vehicle price query message to the server, where the vehicle price query message includes: the method comprises the following steps of presetting vehicle identification and query condition data, wherein the query condition data comprises: and inquiring one or more of time range data, the model of the second-hand modified vehicle and the vehicle depreciation rate interval. It can be understood that since the vehicle is refitted from a second hand, it is naturally impossible to directly evaluate the vehicle according to the depreciation rate, and therefore the consumer needs to change the vehicle from time, vehicle model number, and depreciation rate. And then, the server respectively acquires and returns corresponding second-hand modified vehicle prices from each target block according to the vehicle identification and the query condition data. Due to the fact that the block chain has the characteristic of being difficult to tamper, a consumer can obtain the real price of the second-hand modified vehicle in the mode, and the situation that the consumer is cheated is prevented.
Besides consumers, related government departments can pay attention to the price of the second-hand refitted vehicle so as to supervise whether the second-hand refitted vehicle has the phenomenon of disordered pricing or even disordered refitted. In the embodiment of the application, the query condition data sent by the relevant government department also comprises user identity information so that the server can verify the user identity information. And when the user identity information passes the verification, the server respectively acquires and returns corresponding second-hand modified vehicle sale cost from each target block according to the vehicle identification and the query condition data. Therefore, the price monitoring of government departments can be realized, and personal confidential information can not be easily leaked.
As shown in fig. 2, an embodiment of the present application provides a second-hand modified vehicle condition recording device based on a block chain, including: a receiver 201, a processor 202 and an input device 203;
the processor 202 is configured to arrange a first intelligent contract on each node corresponding to the block chain for recording the second-hand modified vehicle;
