The method of claim 2, wherein, The specific process of classification judgment is as follows: If the current work order is different from the previous assembly work order, the two-dimensional code on the material box is obtained to obtain the material box code; the corresponding information of the material box code and the material code is called, and the material code is obtained by analyzing the material box code; If the current work order is the same as the previous assembly work order, and the current material box quantity is not 0, the material box code bound with the previous assembly is called, the corresponding information of the material box code and the material code is called, and the material code is obtained by analyzing the material box code. If the current work order is the same as the previous assembly work order and the current magazine quantity is 0, a two-dimensional code on a new magazine is obtained to obtain a magazine code; the magazine code and the material code corresponding information are called to analyze the magazine code to obtain the material code.

4. A gearbox line material assembly mistake proofing system based on the gearbox line material assembly mistake proofing method of any one of claims 1-3, characterized in that, The application relates to a transmission line material assembly error-proofing method and device. The first processing module is used for reading a tray label serial number to obtain work order information of the tray, calling the work order information and the station information to obtain station material information corresponding to the tray, and displaying an unscanned background color state; The second processing module is used for obtaining a material traceability code and analyzing the material traceability code to obtain a material code; The comparison and verification module is used for comparing and verifying the material code and the station material information of the tray, when the information comparison is inconsistent, reacquiring the material traceability code and re-comparing and verifying the information with the station material information of the tray; when the information comparison is consistent, the verification is qualified, an already scanned background color state is displayed, and the next process is released to complete the transmission line material assembly error-proofing.

5. A mobile terminal comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, characterized in that, The processor executes the computer program to realize the steps of the transmission line material assembly error-proofing method according to any one of claims 1 to 3.

6. A computer-readable storage medium storing a computer program, the computer program comprising instructions that, when executed by a computer, cause the computer to perform the method of any one of claims 1 to 5. The computer program is executed by the processor to realize the steps of the transmission line material assembly error-proofing method according to any one of claims 1 to 3.
