LAND LEVELER LEVELING CONTROL SYSTEM, CONTROL METHOD, AND LAND LEVELER

摘要

A land leveler leveling control system comprises a datum plane generation device (101), a sensor, a controller (102), and a target instruction input device (103). The sensor comprises an altitude sensor (104). The controller (102) is provided with reference points (a) arranged at intervals with shovel blades in a land leveler. A detection signal comprises an altitude signal indicating a distance from the reference point (a) to an intersection between the altitude sensor (104) and a datum plane (b). The controller (102) comprises a signal calculation unit (1021) used for calculating a location of the reference point (a) relative to the datum plane (b) according to the input detection signal, calculating a target location of the shovel blade relative to the reference point (a) according to the location of the reference point (a) and an input target location signal, performing conversion according to the calculated target location of the shovel blade to obtain a motion quantity of a drive mechanism in the land leveler, and outputting a control signal to the drive mechanism in the land leveler.
