Реферат: The disclosure relates to the technical field of discharge control of internal combustion locomotives, in particular to an emergency discharge control method for an internal combustion locomotive with integrated main and auxiliary structure. The emergency discharge control method comprises: S1. when the locomotive with integrated main and auxiliary structure has a discharge circuit failure, and TCMS determines that a main generator has stopped generating electricity and the TCMS communicates with an auxiliary converter unit and auxiliary inverter normally, manually selecting an emergency discharge working mode through a display screen; S2. after entering the emergency discharge working mode, the TCMS sends an emergency discharge command to the auxiliary converter unit and the auxiliary inverter. In the present invention, when a discharge device or discharge circuit of the internal combustion locomotive with integrated main and auxiliary structure fails, the TCMS of the locomotive controls auxiliary system to enter the emergency discharge working mode to quickly discharge voltage in the main circuit, thereby realizing rapid and safe discharge and ensure personal safety. At the same time, special control strategies are adopted to ensure locomotive operation as much as possible after discharge fault, thus avoiding locomotive breaking due to the discharge circuit failure.
