Control system of generating set of internal combustion electric transmission locomotive

The application discloses a control system of a generating set of an internal combustion electric transmission locomotive. The control system comprises a maintenance staring button, a maintenance stop button, a set controller, a first switch, a second switch, and a switch controller for controlling the switch-off of the first switch and the switch-on of the second switch according to maintenance starting instructions. When the maintenance starting button receives and outputs the starting instruction, the set controller controls the operation of an internal combustion engine; meanwhile, the set controller controls the switch-off of the second switch so that the electric connection of a generator of the generating set and a driving system is cut off; dangers for maintenance personnel in a condition of starting the generating unit without cutting off the electric connection of the driving system and the generator due to the negligence of operation personnel can be prevented.
