60 t mine dumping vehicle control system

Abstract

A 60 t mine dumping vehicle control system comprises a diesel engine set, a convertor, a main generator, a storage battery, a whole vehicle controller, a driver controller, a display screen, a combined instrument, and six motors for driving wheels, wherein the diesel engine set comprises a diesel engine and a 24 V generator; the converter comprises a generator excitation controller, four variable current controllers DCU, an AC / DC converter and six DC / AC converters; the diesel engine is connected with the 24 V generator and the main generator respectively; the 24 V generator provides DC 24 V voltage to the storage battery; the storage battery provides DC 24 V voltage to the whole vehicle controller, the display screen, the combined instrument, the variable current controllers DCU and the excitation controller ECU; the alternative current from the main generator is converted into intermediate direct current by one AC / DC converter, and then the intermediate direct current is converted into three-phase alternative current by six DC / AC converters and the three-phase alternative current provides the power supply to the six motors. Communication based on CAN bus makes the control wiring of the whole vehicle simpler, 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 60-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, diesel engine protection system, hydraulic braking system, hydraulic lifting system, etc. These systems are connected by vehicle controller ACU, transmission controller DCU, diesel engine The CM500 controller and the generator excitation controller ECU 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. large, the system is unstable. [0003] Electric wheel dump trucks have become the key equipment for op...

Problems solved by technology

[0004] With the rapid development of computer control technology in recent years, the traditional "point-to-point" connection method used in automobile lines cannot well meet the requirements of current electric vehicles. The data transmission has good real-time performance and high reliability. When nodes and buses fail Higher requirements for communication systems such as less impact on performance
