Leveler intelligent leveling system and its method

Abstract

An intelligent level system and a related level method for a leveling machine, the system is characterized in that according to the spatial location of a perching knife, the system monitors that a sensor receives signals at the position of the perching knife, and automatically sends out an automatic leveling electric control system of control signals to an electric controlled hydraulic valve which controls a perching knife oil cylinder, and receives control signals of the automatic leveling electric control system to drive an automatic level hydraulic system of the perching knife leveling automatically. The method is as follows: initialization: the parameter setting is judged to be required or not; the sub-program of parameter setting is accessed; the parameter calibration is judged to be required or not; the sub-program of parameter setting is accessed; automatic leveling is judged to be required or not; manual tuning is judged to be required or not; yes, manual tuning is performed; no, a height leveling sub-program and an angle leveling sub-program are performed; the control mode is judged whether M is equal to 0 or not; control signal phases of the left control valve and the right control valve are modulated; the modulated control signal is outputted to an electric control valve for lifting the oil cylinder. The present invention is applicable for precision control of the cross slope, super high turning, road clothoid, etc. with regular change of the cross slope.

Description

technical field [0001] The invention belongs to a leveling system and method for a grader, and in particular relates to a method that enables the grader to perform automatic leveling operations quickly and efficiently, adapting to changes in the transverse slope of ordinary roads, superelevation of curves, and road transition lines according to certain rules. The intelligent leveling system and leveling method of the precise control motor grader. Background technique [0002] Motor graders, as the name suggests, are machines that level the ground and the road. When the motor grader is working, the position of the blade relative to the ground determines its working quality, that is, the flatness of the road surface. The blade of the working device of the grader is installed on a frame that can rotate horizontally, swing vertically and extend laterally. Through the actions of each control hydraulic cylinder, the blade is controlled to lift, rotate, tilt, lead out and change t...

Problems solved by technology

[0004] The automatic leveling system of the grader described in this patent must rely on the edge of the road for operation, and its application is limited in the middle of the road or in places where it is inconvenient to set construction benchmarks; in operation, the main control button and the manual valve control lever are together, which is easy to produce Misoperation
