Protection control system for travel motor

The invention discloses a travel motor protection control system, and belongs to the technical field of engineering machinery. An oil outlet of the oil pump assembly is connected with a first control valve and a second control valve. The first control valve is in control connection with the left walking motor; the second control valve is in control connection with the right walking motor; the controller is electrically connected with the oil pump assembly. The oil pump assembly comprises a first variable pump and a second variable pump; an oil outlet of the first variable pump is connected with a first control valve and a third control valve; the second variable pump is connected with the third control valve, and an oil outlet of the third control valve is connected with the second control valve; and the third control valve is electrically connected with the controller. By monitoring two variables, namely the rotating speed and the continuous use time of the walking motor, the controller automatically stops w
