specific Embodiment approach 1

[0052] Specific implementation mode one: the following combination figure 1 Describe this embodiment, the method for intelligent configuration reading analysis based on the diagnostic protocol described in this embodiment, it includes:

[0053] S1, load the database file, connect to the search engine of the database, enter the password, and perform safe unlocking;

[0054] S2. Perform safety verification on the instrument;

[0055] S3. Directly perform intelligent configuration on the instrument through CAN communication, the intelligent configuration includes: information writing, information reading and information verification.

[0056] In this embodiment, the database file described in S1 is DB271.mdb; the search engine connected to the database is Microsoft.Jet.OLEDB.4.0, and Microsoft.Jet.OLEDB.4.0 is a search engine of an ACCESS database, which is used for the ADO of VB The data control is connected with the ACCESS database code. Select the data project when creating...

specific Embodiment approach 2

[0057] Specific implementation mode two: this implementation mode further explains implementation mode one, and the method for safety verification of the instrument described in S2 includes:

[0058] S2-1. The instrument sends 10 03 to the database to start the extended session;

[0059] S2-2. The instrument receives the response data from the database. If the response data is 50 03, it will respond positively. If the response data is 7F 03, it will respond negatively. When negatively responding, it will prompt a request error;

[0060] S2-3. The instrument sends 27 01 to the database, that is, sends a security access request seed to the database;

[0061] S2-4. The database receives 67 01, that is, the database receives a security access response;

[0062] S2-5. The instrument sends 27 02 to the database, that is, sends the secret key for safe access to the database;

[0063] S2-6. The database receives 67 02, that is, the database receives the security access response key....

specific Embodiment approach 3

[0064] Specific implementation mode three: this implementation mode further explains implementation mode one. The method for directly writing information to the instrument through CAN communication described in S3 includes: writing the hardware version number, writing the hardware batch number, and writing the software version number;

[0065] The configuration information is:

[0066] Send: 10 13 2E 01 00 x[0]x[1]x[2]

[0067] Receive: 0 00 0A 00 00 00 00 00

[0068] Send: 21×[3]×[4]×[5]×[6]×[7]×[8]×[9]

[0069] Send: 22×[10]×[11]×[12]×[13]×[14]×[15]00

[0070] Receive: 03 6E 01 00 00 00 00 00.

[0071] Further, the method for writing the hardware version number includes:

[0072] Send 2E 18 01 xx xx xx to write data;

[0073] Receive 6E 18 01 to get write response;

[0074] The database writes the required hardware version number into the meter through the session with the meter.

[0075] Still further, the method for writing the hardware batch number includes:

Abstract

The invention discloses a method for carrying out intelligent configuration and reading analysis based on a diagnosis protocol, belongs to the technical field of automobile instruments, and aims to solve the problems of complex operation steps of programming, configuration and the like, high manual judgment error rate and low efficiency of an existing instrument. The method comprises the followingsteps: loading a database file, connecting a search engine of a database, inputting a password, and carrying out safe unlocking; performing safety verification on the instrument; making intelligent configuration on the instrument in a CAN communication mode, wherein the intelligent configuration comprises information writing, information reading and information verification. The invention is usedfor detecting, configuring or programming the automobile instrument.

Description

technical field [0001] The invention relates to a method for reading and analyzing intelligent configuration based on a diagnosis protocol, which belongs to the technical field of automobile instruments. Background technique [0002] With the continuous advancement of technology in the field of automotive electronics, the functions of automotive instruments are becoming more and more powerful. Instrument manufacturers need to design different versions of instrument programs according to the high-end models, low-end models or functions of the OEM. [0003] In the production process, the detection, configuration, and programming of the instrument program are usually manually tested for each function one by one, manually configured, and programmed through a programmer. The operation steps of this method are complex, manual judgment is prone to errors, and the efficiency is low. Contents of the invention [0004] The purpose of the present invention is to provide a method for...
