A digital maintenance method for an auxiliary converter module of a motor train unit is characterized in that when detection is started, an upper computer controls a power supply module to start power supply, judges whether an isolation door of a high-voltage area and a low-voltage area is isolated in place or not, and starts a safety warning lamp and a load module after confirming that the isolation door is closed in place; further, the system collects output voltage and current through an output end sensor and carries out fault judgment through a fault diagnosis module; further, a fault maintenance scheme is generated through a fault diagnosis module, a fault type and the scheme are issued to the handheld terminal, and a component disassembly process is generated and issued to the handheld terminal; further, the position of the bolt to be disassembled is indicated through the handheld terminal, meanwhile, the bolt management module determines that the corresponding bolt is disassembled in place, and corresponding operations are repeated until all the bolts to be disassembled are disassembled; further carrying out fault module replacement; further, the position of the bolt to be recovered is indicated through the handheld terminal, meanwhile, the bolt management module determines that the corresponding bolt is taken out correctly, and corresponding operation is repeated until all the bolts to be disassembled are recovered and installed; further, repeating the whole machine test, confirming that the auxiliary transformer module to be tested has no fault, and ending the main process.
7. The digital maintenance method for the auxiliary converter module of the motor train unit according to claim 6, wherein after the fault diagnosis module generates the fault maintenance scheme, it is further required to determine whether the power module needs to be replaced; if the power module needs to be replaced, a power module replacement scheme is issued to the handheld terminal; further, the silicone grease coating module selects a steel mesh type according to the indication of the type of the power module to be replaced, and silicone grease coating is completed; and further, after the silicone grease coating of all the power modules to be replaced is completed, executing a component dismounting process.
