The device is beneficial to the vehicle VIN code writing vehicle controller of the vehicle manufacturing enterprise, which is fast and accurate in the production line end, and avoids a series of problems of sales, quality assurance, license plate feeding, insurance network access and the like caused by the VIN code writing errors.
Description
Technical Field
The invention relates to the technical field of manufacturing automation systems, in particular to a factory end writing device and a detection method for a vehicle identification code VIN.
Background
The vehicle VIN code is used as an electronic identity card of the vehicle, is a unique mark of legal identity in links of vehicle production, sales, quality assurance, license plate, insurance, network access and the like, but when the VIN code is written into a vehicle controller by a factory production line, the VIN code is wrongly written into the vehicle controller due to the fault of writing equipment, unreasonable manual operation flow and the like, and finally, a series of problems of the processes of vehicle sales, quality assurance, license plate, insurance, network access and the like are caused.
The VIN code of the conventional vehicle can be obtained at fixed 3 positions, wherein the positions which are visible to the human eyes on the outside are usually at the left lower corner of the front windshield and the lower side of the door post, but are not easy to damage; the interior is to be identified through special equipment and software reading, the writing is to write the rear end of the assembly production line of the manufacturing enterprise into a certain controller of the vehicle through special equipment and software (without the writing requirement of a fixed controller, each vehicle enterprise operates according to the own whole vehicle strategy and is usually written into the VCU whole vehicle controller Vehicle Control Unit), the writing operation is generally to scan a temporary paper train following single VIN bar code in the vehicle manufacturing process by using a scanning gun by a line producer or to read an external VIN code below the left lower corner of a windshield and a door post and then input the external VIN code into a text input box of VIN code writing software by using a keyboard. There are the following problems: if the following sheets of two vehicles are mixed, the error of writing the VIN code into the vehicles is caused, or the error of reading the external identification code by the personnel on the production line and the error of writing the VIN code into the vehicles is caused.
Disclosure of Invention
The technical problem to be solved by the invention is to provide a factory end writing device for a vehicle identification code VIN. The problem that in the prior art, the VIN code writing operation is generally performed at a VIN code writing station, and if a following list of two vehicles is mixed, the VIN code is written into the vehicle error, or in the latter case, the VIN code is written into the vehicle error due to the fact that a production line personnel reads an external identification code and reads the external identification code and writes the external identification code and the manual identification code.
In order to achieve the above purpose, the present invention provides the following technical solutions: the utility model provides a vehicle identification code VIN mill end writing device includes high accuracy camera, computer and VIN code write-in equipment: the high-precision camera is used for shooting a vehicle VIN code picture at the lower left corner of the windshield, and the computer is used for identifying VIN code character information and uploading the VIN code character information to VIN code writing software after the VIN code character information is successfully matched with the VIN code database at the server side; the VIN code writing device is used for receiving VIN information uploaded by VIN code writing software at a computer end and writing the VIN information into a vehicle controller in the vehicle.
The method for detecting the vehicle identification code VIN factory end writing device comprises the following steps:
the method comprises the steps that firstly, a high-precision camera shoots a vehicle VIN code picture at the left lower corner of a windshield and transmits the picture to a computer;
step two, the computer reads VIN code character information through the VIN code picture and successfully matches the VIN code character information with a server-side VIN code database and then uploads the VIN code character information to VIN code writing software;
and thirdly, the VIN code writing device receives VIN code information uploaded by the VIN code writing software of the computer end and writes the VIN code information into the vehicle controller in the vehicle.
Preferably, in the third step, the VIN code writing device writes the VIN code successfully identified to the in-vehicle controller.
Compared with the prior art, the invention has the beneficial effects that: the method is beneficial to the quick and accurate writing of the vehicle VIN code into the vehicle controller at the production line end of a vehicle manufacturing enterprise, and avoids a series of problems of sales, quality assurance, license plate, insurance, network access and the like caused by the writing error of the VIN code.
