Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the embodiments, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. 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.
At present, generally, whether a vehicle component is replaced or not is judged by means of inquiring a maintenance record, manually judging and the like, so that the problem of poor reliability exists.
To facilitate understanding of the embodiment, first, a detailed description is given to a method for detecting a vehicle component, which is disclosed in the embodiment of the present invention, and is applied to a server, where the server is communicatively connected to an On-board diagnostic (OBD) diagnostic apparatus configured for a vehicle to be detected, where the OBD may monitor information of various components On the vehicle, such as an engine, a transmission, a tire pressure monitoring System, a windshield wiper, a reverse driving assistance System, an instrument panel, an electronic central electrical System, an electronic ignition lock, an airbag, an emergency call module, a communication unit, and the like, and the OBD diagnostic apparatus may read information obtained by monitoring the OBD, see a flowchart of a method for detecting a vehicle component shown in fig. 1, and the method mainly includes the following steps S102 to S108:
and step S102, acquiring the vehicle identification code of the vehicle to be detected.
The vehicle Identification code is also called VIN (vehicle Identification number) code, and the VIN code is usually composed of 17 digits and letters, and is a set of unique serial numbers used for representing data such as manufacturer, engine, chassis serial number and other performances of the vehicle. Generally speaking, a vehicle VIN code is marked on a designated portion (for example, a window portion) of a vehicle to be detected, and a worker can directly check the vehicle VIN code from the designated portion. In addition, the vehicle VIN code can also be saved in a designated storage area of the server, in practical application, the vehicle VIN code is read by using an OBD diagnostic apparatus, and the read vehicle VIN code is saved in the designated storage area, so that the vehicle VIN code of the vehicle to be detected can be directly acquired from the designated storage area when whether the vehicle part is replaced is judged. In addition, if the vehicle VIN code read by the OBD diagnostic apparatus is not consistent with the vehicle VIN code marked at the designated position of the vehicle to be detected, the vehicle VIN code marked at the designated position of the vehicle to be detected may be used as the standard.
And step S104, receiving the vehicle data stream of the vehicle to be detected uploaded by the OBD diagnostic instrument.
The vehicle data stream may include information such as a component identification code (also referred to as a component VIN code) of each component, a vehicle year, a vehicle type, and a data stream of each module, which may be data such as engine operating parameters (e.g., torque). At present, vehicles are generally provided with an OBD and a unified OBD interface, and in one embodiment, an OBD diagnostic instrument may be connected to the OBD interface so as to read a vehicle data stream monitored by the OBD diagnostic instrument, and the OBD diagnostic instrument uploads the read vehicle data stream to a server.
And step S106, extracting the component identification codes of all components in the vehicle to be detected from the vehicle data stream.
The component identification code may be a VIN code, and the VIN code may be a unique serial number used to characterize the manufacturer of the component, etc. In view of the fact that data in a vehicle data stream is relatively cluttered and relatively useless data exists, such as the engine operating parameters are useless data, the component VIN code needs to be extracted from the vehicle data stream, in one implementation mode, filtering rules can be configured in advance, for example, requirements such as the number of characters of a serial number and numbers and letters which can be used by the serial number are configured, if the serial number does not meet the configuration requirements, the serial number is regarded as useless data, the useless data are removed, and the component identification codes of all components in the vehicle to be detected are obtained.
And step S108, comparing the vehicle identification codes with the component identification codes of the components respectively, and detecting replaced components of the vehicle to be detected from the components based on comparison results.
In one embodiment, the vehicle identification code and the part identification code may be compared with each other, and the comparison result may indicate whether the same number of characters are different, the character at a certain designated position is different, the part may be determined to be a replaced part, or the characters at a certain designated position are the same, and the part may be determined to be not replaced.
According to the detection method of the vehicle component, the vehicle data stream uploaded by the OBD diagnostic instrument is obtained, the component identification codes of all the components are extracted from the vehicle data stream, the component identification codes of all the components are compared with the vehicle identification codes respectively, and the replaced components are detected from all the components based on the comparison result.
In particular implementations, embodiments of the present invention detect a replaced component from various components of a vehicle based on a vehicle identification code and a component identification code, however, considering that the data in the vehicle data stream obtained from the OBD diagnostic apparatus is relatively messy and inconvenient to extract the component identification codes of the respective components from the vehicle data stream, the embodiment of the present invention, before extracting the component identification codes from the vehicle data stream, the vehicle data stream may be pre-processed to note useful information in the vehicle data stream, such as part names, part identifiers and identifier names in the vehicle data stream, in a specific embodiment, the component name, the component identification code and the identification code name of each component in the vehicle to be detected contained in the vehicle data stream can be identified, and the component name, the component identification code and the identification code name can be presented in a list form. For ease of understanding, referring to a schematic diagram of a vehicle data stream shown in fig. 2, a component name, a component identification code, and an identification code name in the vehicle data stream are labeled in fig. 2, for example, the component name "sub _ system _ name" (also referred to as a subsystem name) is "ECM (engine module)", the component identification code "ecu _ value" (also referred to as an intra-subsystem data stream data) is "LSGPC 52H7GF 136661", and the identification code name "ecu _ title" (also referred to as an intra-subsystem data stream name) is "vehicle identification code information (VIN)". In practical applications, the identification code names of the vehicle identification codes in vehicles of different models or brands may be different, for example, the part identification code name may also be "VIN code", "vehicle identification number", "frame identification code", "frame identification number", "frame number", or "received chassis number", etc., in order to avoid missing part of the part identification codes due to different identification code names when extracting the part identification codes as much as possible, the embodiment of the present invention may count the commonly used part identification code names, thereby extracting the part identification codes according to the counted identification code names.
After identifying the component name, the component identification code and the identification code name in the vehicle data stream, the embodiment of the invention can also display the component name, the component identification code and the identification code name in a list form, so that the component identification codes of all components are clearer and more intuitive, referring to another schematic diagram of the vehicle data stream exemplarily illustrated in fig. 3, wherein fig. 3 shows the component name, the component identification code and the identification code name in a list form.
On the basis of the preprocessing, the embodiment of the invention provides an implementation mode for extracting the part identification codes of all parts in the vehicle to be detected from the vehicle data stream, and invalid data in the vehicle data stream can be removed according to a preset filtering rule to obtain the part identification codes of all parts in the vehicle to be detected; wherein, preset filtering rules include: and regarding data with the character digits not being the preset digits as invalid data, regarding data containing the specified characters as invalid data, and regarding the characters at the first specified position as the data of the specified characters as invalid data. In one embodiment, since the VIN code is a serial number containing 17-bit characters (including numbers and capital letters), the preset number of bits may be set to 17 bits, that is, data with a character bit number not of 17 bits is regarded as invalid data; in another embodiment, in order to avoid confusion between numbers and letters, wherein numbers "1", "0", "9" and letters "I", "O", "Q" are easy to be confused, letters "I", "O", "Q" may be set as designated characters, for example, data including the above-mentioned letters "I", "O", "Q" is regarded as invalid data; in another embodiment, a specified character at the first specified position may also be set, for example, the 10 th bit is set as the first specified position, and "I", "O", "Q", "U", "Z", "0" is set as the specified character, and if the 10 th bit of data contains the specified character, the data is determined as invalid data.
To facilitate understanding of step S108, the embodiment of the present invention exemplarily provides an implementation of detecting a replaced component of a vehicle to be detected from each component based on the comparison result, specifically referring to (1) to (4) below:
(1) and if the characters of the second appointed position of the component identification code are different from the characters of the second appointed position of the vehicle identification code, and the characters of the third appointed position of the component identification code are the same as the characters of the third appointed position of the vehicle identification code, determining the component corresponding to the component identification code as the replaced component. For example, the ninth to seventeenth bits in the serial number are set as the second designated position, and the first to third bits in the serial number are set as the third designated position, that is, if the first three bits in the part identification code are the same as the first three bits in the vehicle identification code, and the last nine bits in the part identification code are different from the last nine bits in the vehicle identification code, the part corresponding to the part identification code is determined to be the replaced part, and the part is a component to be replaced on another vehicle belonging to the same brand as the vehicle to be detected to the component to be detected on the vehicle to be detected.
(2) And if the part identification code is completely different from the vehicle identification code, determining that the part corresponding to the part identification code is the replaced part. Because the VIN codes of the same brand of vehicle type have certain rules, if the part identification code is completely different from the vehicle identification code and the part identification code has no any rule, the part corresponding to the part identification code can be directly determined as the replaced part.
(3) And if the character of the fourth designated position of the component identification code is the same as the character of the fourth designated position of the vehicle identification code, determining that the component corresponding to the component identification code is not replaced. In general, for a case where a component of a vehicle to be detected is not replaced, the fourth or fifth digit of the component identification code of the component will be different from the fourth or fifth digit of the vehicle identification code, and the characters of the remaining positions will be identical, and therefore, the region positions other than the fourth or fifth digit may be set as the fourth designated position, and if the characters at the fourth designated position are identical and the characters other than the fourth designated position are different, it may be determined that the component corresponding to the component identification code is not replaced.
(4) And if the component identification code is the same as the preset character string, determining that the component corresponding to the component identification code is damaged or the component corresponding to the component identification code is a replaced component. In practical applications, if a component is damaged or an electronic unit of a replaced component is not initialized normally, a VIN reading error will be caused at this time, a VIN code of the component read by the OBD diagnostic apparatus may be "00000000000000000", "AAAAAAAAAAAAAAAAA" or "0123456789 ABCDEFGH", and therefore, the serial number is determined as a preset character string, and when the component identification code is identical to the preset character string, the component corresponding to the component identification code may be damaged and not replaced in time, or the component may be a replaced component but the electronic unit of the component is not initialized normally, and at this time, to know whether the component is a replaced component, a prompt message may be sent to a designated associated terminal to call a worker to perform manual determination.
In one embodiment, in order to facilitate a worker or a user to know a detection result of a vehicle component, in the embodiment of the present invention, after detecting a replaced component in a vehicle, a component identification code and/or a component name of the replaced component of the vehicle to be detected may be sent to a designated association terminal. The designated associated terminal can be a smart phone, a tablet computer or a notebook computer of a user or a worker, for example, the engine is a replaced part, and the part name or the part identification code corresponding to the engine is sent to the smart phone of the worker, so that the worker can check the detection result of the vehicle part through the mobile phone more conveniently.
In order to facilitate understanding of the method for detecting a vehicle component provided in the foregoing embodiment, an embodiment of the present invention provides another method for detecting a vehicle component, referring to a schematic flow chart of another method for detecting a vehicle component shown in fig. 4, where the method mainly includes the following steps S402 to S410:
in step S402, the OBD diagnostic device reads the vehicle information (i.e., the vehicle data stream), and uploads the vehicle information to the server in a report form. The vehicle information may include information such as VIN code, vehicle year, vehicle model, and various module data streams, among others.
In step S404, the server parses the report to obtain a data table. The data table includes a component name, a component identification code, and an identification code name of each component.
Step S406, the server filters the data table to obtain the effective part identification code. In specific implementation, the invalid data in the data table may be removed according to the following rules: (a) eliminating serial numbers with the character digits not being 17 digits; since the VIN code is a serial number including 17-bit characters, and the serial number is composed of numbers and capital letters, in the embodiment of the present invention, when invalid data is removed, the serial number in which the number of character bits is not 17 bits in "ecu _ value" can be removed. (b) And eliminating serial numbers containing English letters 'I', 'O' and 'Q', or eliminating serial numbers with 10 th characters of 'I', 'O', 'Q', 'U', 'Z' and '0'. Given that the number "1" is easily confused with the letter "I", the number "0" is easily confused with the letter "O", and the number "9" is easily confused with the letter "Q", the letters "I", "O", and "Q" are not used in the VIN code, and the 10 th production year does not use "I", "O", "Q", "U", "Z", and "0". (c) The culling characters are all serial numbers of "X". When the OBD diagnostic instrument does not read the component identification code of the component or the component identification code is not written in the VIN, the character string corresponding to the 'ecu _ value' displays 17-bit 'X', and the serial number can be removed.
Step S408, the vehicle identification code is compared with each effective component identification code respectively, so as to judge whether each component has a replacement history according to the comparison result. In one embodiment, the following may exist in the alignment: if a vehicle of a certain vehicle type has a plurality of VIN codes, for example, two series of VIN codes exist, the series of vehicle identification codes and part identification codes are compared for each series of VIN codes, and if the fourth bit or fifth bit character is different and the rest characters are the same, the part can be determined to be not replaced. (II) if the serial number is 00000000000000000, AAAAAAAAAAAAAAAAA or 0123456789ABCDEFGH, the serial number is determined to be abnormal, which may be the situation that the component is damaged, or the component is replaced and the electronic unit of the component is not initialized normally, so that the OBD diagnostic instrument cannot read the identification code of the component correctly, and the situation may prompt a worker to further judge whether the component is a replacement component. And (III) if the first three digits of the part identification code are the same as the first three digits of the vehicle identification code, and the last nine digits of the part identification code are different from the last nine digits of the vehicle identification code, determining that the part is a replaced part, and replacing parts on other vehicles of the same brand of vehicle type with the part on the vehicle. And (IV) if the part identification code is completely different from the vehicle identification code and the part identification code is not regular, determining that the part is a replaced part.
In step S410, the determination results of the respective components are output. In order to facilitate the worker (also referred to as a vehicle inspector) to know the determination result, the determination structure may be transmitted to a designated association terminal of the worker.
In summary, the embodiment of the invention intuitively judges whether the vehicle component is replaced through the VIN code data, and the method does not depend on personal experience of workers and information of third-party service providers which are easy to be tampered, such as maintenance tables and the like, so that the judgment result of whether the vehicle component is replaced is more objective and accurate.
