The invention relates to the field of single-steel-wheel road roller control, and provides a single-steel-wheel road roller control system which comprises a walking gear switch and an electric proportional walking pump. And the walking gear switch selects a walking gear of the single-steel-wheel road roller. The walking gear switch is provided with ten gears, and each gear corresponds to ten gears in different running speed ranges. The whole machine controller is configured to execute the following steps when the electric control handle is located at any one of a forward gear and a backward gear: on the basis of the working mode of an engine of the single-steel-wheel road roller, the displacement of the electric control handle on the gear and the obtained walking gear of the single-steel-wheel road roller, the electric control handle is driven to move on the basis of the working mode of the engine of the single-steel-wheel road roller; the rotating speed of the walking motor is controlled by controlling the input current of the electric proportional walking pump and the input current of the walking motor, so that the running speed of the single-steel-wheel road roller is adjusted. In the working process, the driving speed can be adjusted according to actual needs so as to adapt to various working conditions.
本发明涉及单钢轮压路机控制领域,本发明提供了一种单钢轮压路机控制系统,所述系统包括行走档位开关和电比例行走泵。行走档位开关选择单钢轮压路机行走档位。行走档位开关上设有十个档位,每个档位对应不同的行驶速度范围的十个档位。整机控制器被配置为当电控手柄处于前进档位和后退档位中的任一档位上时执行:基于单钢轮压路机的发动机的工作模式、电控手柄在其所处档位上的位移量以及获取到的单钢轮压路机行走档位,通过控制电比例行走泵的输入电流和行走马达的输入电流,来控制行走马达的转速,以调节单钢轮压路机的行驶速度。本发明用于在工作过程中可以根据实际需要调整行驶速度以适应多种工况。
