Abstract

The invention discloses an electric drive control system for a dumper and a dumper system. The electric drive control system comprises an electric drive unit, an excitation unit and a converter unit. The electric drive unit is used for collecting state information of the dumper and generating control commands based on the state information and a target state, wherein the control commands comprise the excitation command, the traction command and the braking command; the excitation unit receives the excitation command sent by the electric drive unit and regulates a control voltage based on the excitation command, wherein the control voltage is used for achieving traction control or braking control over the dumper; the converter unit receives the traction command or the braking command sent by the electric drive unit and achieves traction control over the dumper based on the traction control command and the control voltage or achieves braking control over the dumper based on the braking command and the control voltage. Compared with a mechanical transmission scheme, the electric drive control system for the dumper is convenient to operate and can lower the later-stage maintenance cost of equipment.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to an electric drive control system of a dump truck and a corresponding dump truck system. Background technique [0002] At present, dump trucks are mainly used for medium and short-distance material transportation in open-pit mines, hydropower construction sites, ports and other operating sites, and can be used in harsh operating environments such as mud puddles and wavy roads. Work on turning road conditions. [0003] However, existing dump trucks generally adopt mechanical transmission or hydromechanical transmission schemes. The above two transmission schemes are inconvenient to operate, and the cost of maintaining the mechanical parts in the later period of the dump truck is high. Contents of the invention [0004] In order to solve the above problems, the present invention provides an electric drive control system applied to dump trucks and a corresponding dump tru...
