The two-dimension code acquisition refers to that when the automobile controller is configured in a factory, software configuration information configured in the automobile controller is simultaneously converted into two-dimension code information, then when a new replaced controller needs to be written, the two-dimension code is shot through a camera of the after-sales diagnosis device, and then the controller in the after-sales diagnosis device identifies and stores corresponding software configuration information through a two-dimension code identification software program. And then the automobile is connected through the diagnosis port, the configuration information is written into the automobile controller through the write-in instruction, after the write-in is finished, the software configuration information of the automobile controller is read again through the read instruction and is compared with the written configuration information, so that whether the write-in is successful or not is reminded according to the consistency, and the reminding is reminded through the display reminding information of the after-sales diagnosis equipment. The memory entry mode is that for an automobile needing to be replaced by a new controller, the automobile is connected through an OBD diagnosis port, software configuration information of an automobile controller is read through a read instruction and then stored, when the automobile is replaced by the new controller, the automobile is connected through the OBD diagnosis port, the read software configuration information of the old controller is written into the new controller, writing is completed, after writing is completed, the software configuration information in the new controller is read again through the read instruction and compared with the written software configuration information, and then a prompt of whether writing is successful or not is given. The mode of memory entry needs to read the software configuration information of the old controller, and the mode needs to confirm the readability, no damage and other conditions of the old controller.
The method has the advantages that the existing extensive two-dimensional code technology is utilized, manual input is not needed, the whole vehicle software configuration information can be obtained through simple scanning and then written in through after-sales diagnosis equipment, or the last stored whole vehicle configuration information is called to complete writing in through the memory function of the diagnosis equipment, the two methods are simple, fast and effective, and the time of manual input and the probability of errors are greatly reduced.
As shown in fig. 1, a two-dimensional code, also called a two-dimensional barcode, is an encoding method that is popular in mobile devices in recent years, and can store more information and represent more data types than a conventional barcode. Fig. 1 is an example of a two-dimensional code, and it can be seen that 16-ary data of 94 bytes is converted into a two-dimensional code. The after-sale diagnostic equipment can acquire the 16-system data of 94 bytes by only scanning the two-dimensional code.
