Abstract

A control system of a 220t mine dump vehicle comprises a vehicle control unit ACU, drive control units DCU, a generator excitation control unit ECU, a diesel engine control unit CM500 and a speed odometer. The vehicle control unit ACU, the drive control units DCU, the generator excitation control unit ECU and the diesel engine control unit CM500 are connected and communicated with one another through a CAN (controller area network) bus. The vehicle control unit ACU is in RS485 communication with a weighing display. The vehicle control unit ACU receives instructions of a cab control platform and sends the processed instructions to the drive control units DCU and the generator excitation control unit ECU to complete traction, brake, forward movement and backward movement of a vehicle. The control system further comprises a display system, a signal detection system, a weighing system, a diesel engine protection system, a hydraulic braking system, a hydraulic lifting system and a self-diagnosing system. Each sub system is based on CAN bus communication, so that control wiring of the whole vehicle is simple and less prone to electromagnetic interference, and the control system is stable and reliable.

Description

technical field [0001] The invention relates to a mine dump truck, especially a control system for a 220-ton mine dump truck. Background technique [0002] The dump truck control system is huge and complex, especially for large-tonnage mining dump trucks. The general mining dump truck control system includes status display system, signal detection system, weighing system, diesel engine protection system, hydraulic braking system, hydraulic lifting system, etc. These systems are connected by the vehicle controller ACU, transmission control The generator DCU, the generator excitation controller ECU, and the diesel engine controller CM500 are interrelated, so that the dump truck can drive and lift smoothly. At present, most electric wheel dump trucks are connected by wire harnesses, and all electrical equipment such as vehicle controllers, display instruments, various lights, solenoid valves, sensors, etc. The system is functioning normally.
