Abstract

MÉTODO, APARELHO E SISTEMA DE CONTROLE DE NIVELAMENTO, MOTONIVELADORA, E, MEIO ARMAZENÁVEL EM COMPUTADOR. A presente revelação se refere a um método e sistema de controle de nivelamento, um controlador, uma motoniveladora e um meio armazenável em computador, relacionando ao campo técnico de maquinaria de construção. O método de controle de nivelamento compreende: obter a elevação da posição corrente de uma lâmina de uma motoniveladora, a elevação de uma posição alvo e a velocidade de movimento da motoniveladora, respectivamente, dita posição alvo estando sobre o solo que tem uma certa distância horizontal da posição corrente ao longo da direção de movimento da motoniveladora; de acordo com a distância horizontal e a velocidade de movimento, determinar um tempo de movimento da lâmina da posição corrente para a posição alvo; de acordo com a diferença de elevação entre a elevação da posição alvo e a elevação da posição corrente e o tempo de movimento, determinar a velocidade de levantamento/ abaixamento de um cilindro de levantamento/abaixamento; controlar o cilindro de levantamento/abaixamento de acordo com a velocidade de levantamento/abaixamento e ajustar a lâmina a partir da posição corrente para a posição alvo. De acordo com a presente revelação, a precisão do nivelamento é melhorada.
