A dual engine control system

Abstract

The invention belongs to the technical field of engine control and discloses a double-unit-engine control system used for controlling engines of a mining dump truck. The control system comprises a signal acquisition module, a control unit and an engine starting and stopping control executing module, wherein the signal acquisition module is used for acquiring real-time operation parameters and enabling signals of two engines and the mining dump truck; the control unit receives the parameters of the signal acquisition module, performs calculation and outputs a control command; the engine starting and stopping control executing module receives the control command and controls the engines to act; the control unit comprises a mode control module and a starting and stopping diagnosis module, and the starting and stopping diagnosis module comprises an engine starting module and an engine stalling module. According to the real-time operation parameters, acquired by the signal acquisition module, of the engines and the mining dump truck, a double-engine starting and stopping instruction is calculated and output, wherein the operation parameters of the two engines comprise the rotating speed of the engines, the temperature of cooling liquid of the engines and pressure of supporting legs of the whole truck. Through the system, double-unit automatic starting and stopping control is achieved, control efficiency is improved, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of engine control, in particular to a dual-unit engine control system. Background technique [0002] Traditional electric wheel mining vehicles are mostly single-power drive dump trucks. Unlike passenger cars, many of the work of the vehicle is done at idle speed or under light load conditions, so as long as the vehicle is in working condition, the engine cannot be easily turned off but must be kept on. The automatic engine start and stop technology is not feasible on single-power electric wheel dump trucks. [0003] Dual-unit electric wheel mining vehicles refer to mining vehicles that use two independent power systems to provide power sources for their respective electric drive systems on one mining vehicle. This type of vehicle has two engines, two generators and The independent electric drive system can work independently without affecting each other. At this stage, the start and stop of the engine of...

Problems solved by technology

At this stage, the start and stop of the engine of the dual-unit mine car is still manually controlled, and the operator manually starts or stops the other engine to enter the dual-unit working state or the single-unit working state; it seriously affects the vehicle control and causes unnecessary energy consumption. waste
