Automatic leveling system of milling machine and implementation method
The invention relates to an automatic leveling system of a milling machine and an implementation method, and solves the problem that the milling machine in the prior art does not have an automatic leveling function when working on a road surface with a complex working environment. The system comprises an electronic gyroscope, an ECU main controller, a hydraulic control valve body and a walking hydraulic stand column, the electronic gyroscope and the hydraulic control valve body are electrically connected with the ECU main controller, the walking hydraulic stand column is connected with the hydraulic control valve body through a hydraulic oil pipe, the electronic gyroscope is arranged in the center of a milling machine vehicle body, the ECU main controller is arranged in an electrical control cabinet, and the hydraulic control valve body is arranged in the electrical control cabinet. The electronic gyroscope converts the attitude information of the milling machine during operation into Euler angle data flow, the Euler angle data flow is fed back to the main control unit ECU through the CAN interface bus for resolving, and an electromagnetic valve PWM control signal for lifting of the hydraulic stand column of the vehicle body is formed through a compensation algorithm; and the closed-loop control system is used for controlling the posture of the vehicle body in real time to keep the vehicle body within a parallel swinging range conforming to construction standards.
