Embodiment approach
[0049] As a preferred embodiment of the present invention, the method also includes a method of performing tasks in multiple threads, specifically including the following steps:
[0050] (1-1) Initialize thread of communication connection, initialize host computer interface, initialize USBCAN converter device;
[0051] (1-2) The main thread of verification algorithm and flashing command generates the host computer check bit, and sends the flashing command to the car CAN bus through the USBCAN converter;
[0052] (1-3) The receiving thread receives CAN bus messages from the lower computer in real time, and obtains the writing information of the lower computer.
[0053] As a preferred embodiment of the present invention, the writing information of the lower computer in the step (1-3) includes the communication status, the VIN code writing result and the VIN code written last time.
[0054] In the specific implementation of the present invention, Labview uses graphical editing language to ...

The invention relates to a system for realizing vehicle VIN code flashing verification based on Labview. The system comprises a computer host which is used as an upper computer and is used for operating a verification algorithm and sending a flashing command; the USBCAN conversion card is used as a converter between the upper computer communication interface and the lower computer communication interface; the lower computer communication interface is used for providing an automobile CAN bus signal; and the vehicle control unit is used as a lower computer, runs a lower computer verification algorithm, and matches and compares the lower computer verification algorithm with the upper computer verification result. The invention further relates to a vehicle VIN code flashing verification methodbased on the Labview. According to the system and method for achieving vehicle VIN code flashing verification based on Labview, tasks are operated in parallel based on a Labview multi-thread task system, flashing response is fast, interface functions are diversified, and a verification algorithm can effectively prevent VIN codes from being mistakenly flashed or tampered.
Description
Technical field [0001] The invention relates to the field of automotive electronics, in particular to the technical field of multithreaded control, and specifically refers to a system and method for implementing vehicle VIN code brushing verification based on Labview. Background technique [0002] The vehicle identification code (VIN code) is a set of unique numbers used on cars, usually composed of 17 characters, which is the abbreviation of English Vehicle Identification Number. Each character in the VIN has a specific meaning like a fingerprint of a car, including the car's manufacturer, engine, chassis number and other performance information. [0003] Labview is a graphical language programming platform with multi-threaded control technology that can execute multiple independent tasks in parallel, improving system fault tolerance and stability. [0004] The existing traditional VIN code flashing method, the verification algorithm is limited to the upper computer side, lacks the...
