The digital maintenance method of the auxiliary converter module of the motor train unit is characterized in that when detection is started, an upper computer controls a power module to start power supply, judges whether a high-low voltage area isolation door is isolated in place, and starts a safety warning lamp and a load module after closing in place; the system collects output voltage and current through an output end sensor and performs fault discrimination through a fault diagnosis module; generating a fault maintenance scheme through a fault diagnosis module, issuing fault types and schemes to the handheld terminal, and simultaneously generating a component disassembly flow and issuing to the handheld terminal; the position of the bolt to be disassembled is indicated through the handheld terminal, meanwhile, after the bolt is inserted into the bolt accommodating groove and accommodated in place through the bolt management module, the pressure spring is compressed, the upper contact and the lower contact are connected, a high-level signal is input into the bolt management controller, after the corresponding high-level signal is received by the bolt management controller, the bolt accommodating in-place signal is sent to the bus through the bolt management input/output module, the corresponding bolt is determined to be disassembled in place, and the corresponding operation is repeated until all the bolts to be disassembled are disassembled; performing fault module replacement; the position of the bolt to be recovered is indicated by the handheld terminal, the corresponding bolt is determined to be taken out correctly by the bolt management module, and the corresponding operation is repeated until all the bolts to be disassembled are recovered and installed; and repeating the whole machine test, confirming that the auxiliary transformer module to be tested has no fault, and ending the main flow.
5. The method for digitally maintaining an auxiliary converter module of a motor train unit according to claim 4, wherein after the fault diagnosis module generates a fault maintenance scheme, it is further determined whether a power module replacement is required; if the power module needs to be replaced, a power module replacement scheme is issued to the handheld terminal; the silicone grease coating module selects a steel mesh type according to the type indication of the replacement power module, and finishes silicone grease coating; and after finishing the silicone grease coating of all the power modules to be replaced, executing a component disassembly flow.
