Control system for mine electric wheel dump truck by using fieldbus technology

Abstract

The invention discloses to a control system for a mine electric wheel dump truck by using fieldbus technology, which relates to electronic control on vehicles. The control system comprises a fieldbus controller and devices for electric wheel trucks on the bus, which are controlled by the fieldbus controller, wherein the fieldbus controller comprises a main controller and one or a plurality of subcontrollers; the main controller is used for acquiring driving signals and controlling the power system; and the subcontrollers are used for acquiring other operation signals and controlling the auxiliary electrical system and hydraulic system; and the main controller and subcontrollers communicate information through the bus and transmit the data to be displayed to the display screen and meters. The invention solves the problem of long and complicated entire truck route caused by the traditional wiring mode; the devices can be installed in flexible positions; the vehicle power unit has the advantages of high response speed and high control accuracy; the fiber is used as the transmission medium of the heavy-current power control bus, thereby avoiding electromagnetic interference and ensuring data transmission accuracy; and multiple network buses are utilized to avoid busyness and enhance safety.

Description

technical field [0001] The present invention relates to the electronic control of vehicles, in particular to a control system of a mining electric wheel dump truck using field bus technology, and a distributed control system for the power circuit, hydraulic system and auxiliary electrical of a high-power mining electric wheel dump truck. Control Technology. Background technique [0002] Field bus is a kind of digital network applied to the process control field, and it is the embodiment of digital control. It includes not only the exchange of process control information, but also the exchange of equipment management information. Through the field bus, various intelligent devices (intelligent transmitters, regulators, analyzers and distributed I / O units) can exchange data conveniently, and the process control strategy can be completely implemented at the field device level. Fieldbus technology has been widely used in the industrial field. [0003] With the rapid developmen...

AI Technical Summary

Problems solved by technology

Existing mine electric wheel dump trucks at home and abroad mainly adopt traditional board-type control. The control modules are scattered, single-function, complicated wiring, low space utilization, and due to the harsh working environment (large heat generation, poor heat dissipation conditions, electromagnetic Strong interference), resulting in low control accuracy and high failure rate. In places with strong electromagnetic interference, even if shielded wires are installed, the accuracy and stability of the signal are still not guaranteed
