Fig. 3 is a flowchart of a method for retrieving a vehicle accessory according to an embodiment of the present invention, and the method specifically includes steps S201 to S209.
S201: acquiring a VIN code from a client, and analyzing the vehicle identity information of the VIN code;
in order to obtain the VIN code and realize automatic analysis of the vehicle identity information reflecting the vehicle identity in the VIN code, the VIN code is obtained from the client, and the automatic analysis of the VIN code is realized in a mode of analyzing the vehicle identity information of the VIN code by an analysis algorithm.
The VIN code is a Vehicle Identification Number (or frame Number), abbreviated as VIN, and is a set of seventeen letters or numbers, and is used for a unique set of numbers on an automobile, and can identify data such as manufacturer, engine, chassis serial Number and other performances of the automobile. In order to avoid confusion with numbers 1, 0 and 9, English letters "I", "O" and "Q" are not used, and "I", "O", "Q", "U", "Z" and "0" are not used in the 10 th production year.
Since the VIN code creation rules of different countries and brands are different, in order to accurately analyze the VIN code creation rules of different countries and brands, in this embodiment, the analysis algorithm is to disassemble the VIN codes to obtain at least one code value, obtain vehicle information from a preset VIN code mapping table according to the code value and the position of the code value in the VIN codes, and summarize the vehicle information to form vehicle identity information.
Illustratively, when acquiring the VIN of 1G1BL52P7TR115520, obtaining a code value of 1 and locating the first bit in the VIN code, from the VIN code mapping table, the vehicle information will be obtained: the united states.
In a preferred embodiment, a method for obtaining a VIN code quickly is provided for a client, and a problem that the working efficiency of the client is low due to manual input of the VIN code is avoided, where the step of obtaining the VIN code from the client includes:
s1-01: receiving a shooting identification request sent by a client
S1-02: starting a shooting module of the client, acquiring the character image shot by the shooting module,
in this step, the shooting module is computer software preset in a client (such as a smart phone) for shooting pictures.
S1-03: and calling an OCR system to identify the VIN code in the character image.
In this implementation, an OCR (Optical Character Recognition) system refers to a computer system that an electronic device checks a Character printed on paper, determines its shape by detecting dark and light patterns, and then translates the shape into a computer text by a Character Recognition method. Computer software such as OCR Space, Chike OCR, etc. can be used as the OCR system.
In a preferred embodiment, a VIN code can be obtained quickly for a user who does not have a shooting device (e.g., a computer without a camera), and the problem that the working efficiency of a client is low due to manual input of the VIN code is avoided, where the step of obtaining the VIN code from the client includes:
s1-11: sending an image uploading request to a client, and receiving a text image sent by the client according to the image uploading request;
s1-12: and calling an OCR system to identify the VIN code in the character image.
In this implementation, an OCR (Optical Character Recognition) system refers to a computer system that an electronic device checks a Character printed on paper, determines its shape by detecting dark and light patterns, and then translates the shape into a computer text by a Character Recognition method. Computer software such as OCR Space, Chike OCR, etc. can be used as the OCR system.
In a preferred embodiment, if the OCR system cannot acquire the VIN code of the vehicle through the photographing module and the image, in order to ensure that the VIN code of the vehicle can still be normally acquired, so as to ensure stability and reliability of the system, the step of acquiring the VIN code from the client includes:
s1-21: and sending a text dialog box to the client.
In this step, a dialog box with an input box may be used as the text dialog box to record the VIN code entered by the client.
S1-22: and receiving the VIN code sent by the client according to the text uploading request.
S202: acquiring a verification rule corresponding to the vehicle identity information, verifying the VIN code according to the verification rule, acquiring a verification result, and judging whether the VIN code passes the verification of the verification rule; if yes, the vehicle identity information is judged to be qualified in verification, and S203 is executed; if not, deleting the VIN code and the vehicle identity information thereof, sending an inquiry selector to the client, acquiring the vehicle identity information selected by the client in the inquiry selector, and executing S203.
In the process of acquiring the VIN code, the VIN code may be erroneously acquired due to a wrong client entry or a wrong OCR system identification, or the VIN code on the vehicle is a fake and invalid VIN code, so as to avoid that the acquired vehicle identity information is wrong, a correct code library cannot be acquired, the feedback accuracy of the code library is poor, and the operation efficiency is low.
The method comprises the steps that a check library which stores vehicle identity information and check rules is provided, wherein a mapping relation exists between the vehicle identity information and the check rules in the check library, and the check rules are computer algorithms for verifying whether the VIN codes conform to the check codes in the check library, so that the risk that the VIN codes are wrong VIN codes or invalid VIN codes is eliminated. Since the VIN code creation rules of different countries and brands are different, in order to accurately check the VIN codes of different countries and brands, the step of obtaining the check rule corresponding to the vehicle identity information ensures that the VIN codes can be checked by the accurate check rule.
If the VIN code passes the verification of the verification rule, it indicates that the VIN code is qualified, so S203 can be directly executed; if the VIN code does not pass the verification of the verification rule, the VIN code is wrong or invalid, and the vehicle identity information obtained based on the VIN code is wrong, so that the VIN code and the vehicle identity information thereof are deleted to reduce the occupation of invalid information on a system memory, an inquiry selector is sent to the client, and the vehicle identity information selected by the client in the inquiry selector is obtained to obtain the vehicle identity information capable of accurately reflecting the vehicle identity.
In this embodiment, the verification rule includes: sequentially acquiring corresponding values of code values of the VIN code except the check code from the first bit of the VIN code, multiplying the corresponding values by weighted values corresponding to the positions of the code values to obtain a total value, and dividing the total value by a preset check number to obtain a remainder as a value to be checked; judging whether the value to be checked is public with a check code in the VIN code; if so, judging that the VIN code passes the verification of a verification rule; if not, the VIN code is judged to pass the check of the check rule.
Exemplarily, the following steps are carried out: vehicle identification code: the ninth bit of UU6JA69691D713820 is 9 as a check code, and we can verify whether the code is correct. Assuming that U corresponds to 4, 6 corresponds to 6, J corresponds to 1, a corresponds to 1,9 corresponds to 9, D corresponds to 4, and meanwhile, the weight of the VIN code for the first bit is 8, the weight of the second bit is 7, the weight of the third bit is 6, the weight of the fourth bit is 5, the weight of the fifth bit is 4, the weight of the sixth bit is 3, the weight of the seventh bit is 2, the weight of the eighth bit is 10, the weight of the tenth bit is 9, the weight of the eleventh bit is 8, the weight of the twelfth bit is 7, the weight of the thirteenth bit is 6, the weight of the fourteenth bit is 5, the weight of the fifteenth bit is 4, the weight of the sixteenth bit is 3, and the weight of the seventeenth bit is 0, the total VIN code obtained by calculating the check rule is as follows: 4 × 8+4 × 7+6 × 6+1 × 5+1 × 4+6 × 3+9 × 2+6 × 10+1 × 9+4 × 8+7 × 7+1 × 6+3 × 5+8 × 4+2 × 3+0 × 0 is 350, the total code 350 is divided by the parity number 11 to obtain 31, and the remainder 9 is the code to be verified.
In fig. 3, the step S202 is shown by the following labels:
s21: acquiring a verification rule corresponding to the vehicle identity information, verifying the VIN code according to the verification rule and acquiring a verification result;
s22: judging whether the VIN code passes the verification of the verification rule;
s23: if yes, the vehicle identity information is judged to be qualified in verification, and S203 is executed;
s24: if not, deleting the VIN code and the vehicle identity information thereof, sending an inquiry selector to the client, acquiring the vehicle identity information selected by the client in the inquiry selector, and executing S203.
S203: and identifying index information matched with the vehicle identity information from a preset index library, and acquiring a code library associated with the index information, wherein the code library is used for storing accessory names and OE numbers thereof.
In order to accurately identify the vehicle corresponding to the VIN code, the accessory name of the vehicle and the OE number of the accessory based on the VIN code, the accessory names and the OE numbers of all accessories in the vehicle are accurately obtained in a mode of identifying index information matched with the vehicle identity information from a preset index library and obtaining a code library associated with the index information.
Wherein, OE number is in developed country of automobile manufacturing industry, each automobile manufacturer manages parts for convenience, each part of each automobile type is classified by different numbers, the number is OE number, therefore, all OE numbers under vehicle identity information corresponding to a certain VIN code have uniqueness, and index information and OE numbers are used as inquiry product information
In a preferred embodiment, the index library is constructed by the steps comprising:
s3-01: acquiring a creation rule of a training VIN code, wherein the creation rule comprises definition information reflecting each code value in the training VIN code;
illustratively, take the VIN code creation rule of the ford motor company, usa as an example, it includes:
the first bit: country code of production, second bit: production or entry department code, third digit: vehicle type category code, fourth bit: occupant safety protection device code, fifth bit: vehicle type serial code, sixth to seventh bit: body type code, eighth bit: engine model code, ninth digit: VIN check number code, tenth: vehicle type year code, eleventh bit: total assembly factory code, twelfth bit: a factory sequence number code.
S3-02: and extracting definition information reflecting the vehicle identity corresponding to the training VIN code in the creating rule to obtain an identity rule.
Illustratively, the vehicle identities include brand and manufacturer, vehicle family, annual fee; therefore, the definition information of the first digit, the second digit and the third digit of the training VIN code in the creation rule is set as the definition information reflecting the brand and manufacturer of the vehicle, namely: the first bit: country code of production, second bit: production or entry department code, third digit: a vehicle type category code; and obtaining definition information for reflecting the train by the fifth bit code value, namely: the fifth position: vehicle type series codes; and obtaining definition information of the reaction year money by extracting the tenth code, namely: the tenth position: a vehicle type year money code; and summarizing the definition information to obtain the identity rule.
In this embodiment, the identity rule in the creation rule may be extracted through a preset regular expression or a keyword, where the regular expression and the keyword may be set as required.
S3-03: creating nodes for recording each definition information in the identity rule, and taking the former node in the two adjacent nodes as the father node of the latter node based on the bit of the definition information in the identity rule so as to construct the nodes into a database with a tree-shaped data structure.
In this step, the tree data structure is an important nonlinear data structure. The tree data structure may represent a one-to-many relationship between data table elements. The tree and the binary tree are most commonly used, and the tree is a hierarchical structure defined by a branch relation in an intuitive view. Tree data structures are widely available in the objective world, for example, the genealogy of human society and various social organizations can be represented visually by tree data structures.
Illustratively, based on the above example, each node defining information in the identity rule includes: a first node: brand and manufacturer; the second node: vehicle type; a third node: and (5) the year money. Since the rank of the definition information in the identity rule is a country code of production, a department code of production or entry, a vehicle type category code, a vehicle type series code, a vehicle type year code, the first node is taken as a parent node of the second node, the second node is taken as a parent node of the third node, and thus, a database having a tree-like data structure from the first node to the fifth node is obtained.
S3-04: and acquiring at least one training VIN code, sequentially analyzing code values of the training VIN code according to definition information in the identity rule to obtain index information, and loading the index information into a node corresponding to the definition information in the database to obtain an index database.
In this step, the code value of the training VIN code is analyzed by an analysis algorithm according to definition information in the identity rule to obtain the index information, where the analysis algorithm is to disassemble the VIN code to obtain at least one code value, and according to the code value and the position of the code value in the VIN code, the index information is obtained from a preset training VIN code mapping table, where the training VIN code mapping table is a data table reflecting mapping relationships between the code value in the training VIN code, the position of the code value in the VIN code, and the index information, such as: the LFM is located at the first, second and third position in the training VIN code, and the corresponding index information is Toyota, a gasoline Toyota auto Joint venture.
Illustratively, a training Vin code is obtained: the LFMARE2C190216092, according to the first, second and third bit code values LFM, obtains index information reflecting brand and manufacturer: toyota, a gasoline Toyota auto Joint Co; obtaining a vehicle type according to the fifth bit code value R: a clamping roller; according to the tenth code value of 9, the annual fee is obtained: 2009; loading Toyota, Toyota auto Joint Commission company into the first node, and loading Ka roller into the second node; and loading '2009' into the third node.
In a preferred embodiment, the code library is constructed by the steps comprising:
s3-11: and sending the index information in the index database to a control end, and receiving the vehicle style sent by the control end.
Illustratively, the vehicle style is a leading style, a elite style, a luxury style, and the like.
S3-12: acquiring the accessory information from an EPC inquiry system according to the index information and the name information, and storing the accessory information into a preset accessory library, wherein the accessory information comprises an accessory name and an OE number thereof.
S3-13: if the number of the vehicle styles is one, setting the accessory library as a code library, associating the accessory library with the index information, and loading the vehicle styles into the code library;
s3-14: if the number of the name information is more than one, identifying public information and difference information in the accessory information, associating the public information and the difference information with the index information, and associating the difference information with the name information; the common information refers to accessory names and OE numbers of the accessory information corresponding to all vehicle styles, and the difference information refers to accessory information corresponding to any vehicle style and is different from accessory names and OE numbers of the accessory information corresponding to other vehicle styles.
Acquiring accessory information corresponding to any two pieces of name information, constructing accessory characteristics of each accessory name in the accessory information, recording the accessory characteristics in a preset planar rectangular coordinate system in a scatter point mode to obtain a scatter point diagram, and calculating the scatter points in the scatter point diagram by calling a preset linear regression model to divide to obtain a dividing line; calculating the Euclidean distance between the scattered points and the dividing line, and if the Euclidean distance of the scattered points is smaller than a preset classification threshold, setting the accessory names and OE numbers thereof corresponding to the scattered points as public information; and if the Euclidean distance of the scattered points is greater than the classification threshold, setting the accessory information and OE numbers thereof corresponding to the scattered points as difference information.
It should be noted that the EPC query system is a full-vehicle type full-accessory high-precision accessory query system, which is used for a computer system, such as a car friend network, for obtaining accessory information of a vehicle according to vehicle identity information of the vehicle.
S204: and judging whether the vehicle style in the code library is empty or not.
S205: if the vehicle style is empty, a query selector is sent to the client, the vehicle identity information selected by the client in the query selector is obtained, the index information matched with the vehicle identity information in the index database is identified, the code database associated with the index information is obtained, and then S206 is executed.
Because vehicles of the same brand, train or year use accessories of the same OE number, in order to solve the problem that the OE number of corresponding accessory information cannot be obtained through VIN codes due to incomplete index libraries, the method comprises the steps of judging whether the vehicle style in the code library is empty, sending a query selector to a client in a mode that the vehicle style is empty, enabling the client to form vehicle identity information by selecting information such as the corresponding brand, train, year, vehicle style and the like in the query selector, obtaining index information matched with the vehicle identity information from the index library, obtaining the code library associated with the index information, and providing the code library corresponding to the vehicle of which the brand, train and/or year is close to a query target vehicle for the client so as to ensure that the client can obtain the required accessories and OE numbers thereof, thereby ensuring the comprehensiveness and reliability of information retrieval.
S206: and if the vehicle style is not empty, judging whether the vehicle style is unique.
S207: and if the vehicle style is unique, storing the accessory name and the OE number in the code library into a preset cache module, and sending a query dialog box to the client.
If the vehicle style is only one style, the client does not need to select the corresponding vehicle style, only needs to send the accessory name and the OE number thereof in the coding library to the cache module, and sends a query dialog box to the client for comparing the accessory name sent by the client, so that the system operation efficiency is improved.
S208: and if the vehicle style is not unique, sending the vehicle style to the client, receiving the vehicle style selected by the client, setting the vehicle style as a target style, storing the accessory name and the OE number thereof corresponding to the target style in the coding library into a preset cache module, and sending a query dialog box to the client.
Since the accessory names of different vehicle models may be the same, but the OE numbers corresponding to the accessory names are different, for example: the Ka roller leading version of the tire was 18 inches, while the Ka roller luxury version of the tire was 19 inches, so the different sizes of OE numbers were different. Therefore, in order to ensure that an accurate OE number can be obtained and accurate product information is returned to the client, the vehicle style is sent to the client when the vehicle style is more than one, so that the client can select a required target style according to needs, store an accessory name corresponding to the target style and the OE number of the accessory name into the cache module, and send a query dialog box to the client.
S209: acquiring a query entry input by the client in the query dialog box, identifying an accessory name corresponding to the query request from the cache module, and acquiring an OE number of the accessory name; and acquiring product information corresponding to the index information and the OE number from a preset product library, and sending the product information to the client.
In order to avoid the problem that the product information required by the client cannot be accurately returned due to the fact that the input OE number is wrong because the client inputs the complicated OE number, in the step, the accessory name corresponding to the query request is identified from the cache module by obtaining the query entry input by the client in the query dialog box, and the OE number of the accessory name is obtained.
The client can obtain the OE number of the accessory name corresponding to the query entry only by inputting the query entry, so that the product information required by the client can be obtained from the product library through the accurate OE number, and the accuracy of obtaining the product information is improved.
After the sending the product information to the client, the method further includes:
and uploading the product information to a block chain.
It should be noted that the corresponding digest information is obtained based on the product information, and specifically, the digest information is obtained by hashing the product information, for example, by using the sha256s algorithm. Uploading summary information to the blockchain can ensure the safety and the fair transparency of the user. The user equipment can download the summary information from the blockchain so as to verify whether the product information is tampered. The blockchain referred to in this example is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, and the like. A block chain (Blockchain), which is essentially a decentralized database, is a series of data blocks associated by using a cryptographic method, and each data block contains information of a batch of network transactions, so as to verify the validity (anti-counterfeiting) of the information and generate a next block. The blockchain may include a blockchain underlying platform, a platform product service layer, an application service layer, and the like.
