Design of Intelligent Spray Dust Reduction System for Scraper Conveying Equipment

针对刮板输送装备所用传统喷雾降尘系统无法适应不同条件下喷雾要求且喷雾降尘效果不佳的问题,基于参数自整定模糊控制思想,对喷雾降尘系统的关键参数进行自动调节,实现了喷雾降尘系统的智能化运行。首先,基于高斯分布函数建立喷雾压力模糊控制的数学模型,并采用误差反向传播算法优化了模型参数;其次,通过设计模糊控制规则对喷雾压力进行了调整;最后,根据刮板输送装备转载点、破碎点的位置特点以及降尘要求,完成了智能喷雾降尘系统的软件和硬件设计。实践表明:引入误差反向传播算法整定模糊控制参数后,喷雾降尘系统更能适应井下环境;所设计智能喷雾降尘系统优化后的喷雾压力能节约井下用水,且降尘效果良好。

The scraper conveying equipment needs to be sprayed to reduce dust pollution during use.However,the traditional spray system is often unable to adapt to the spray requirements under different conditions,resulting in poor spray effect.Therefore,this paper introduces the idea of parameter self-tuning fuzzy control,and realizes the intelligence of the spray system by automatically adjusting the key parameters of the spray system.Firstly,the mathematical model of spray pressure fuzzy control is established based on Gaussian distribution function,and the model parameters are optimized by error back propagation algorithm.Secondly,the spray pressure is adjusted by fuzzy control rules.Finally,according to the position characteristics of the transfer point and the crushing point of the scraper conveying equipment and the dust reduction requirements,the hardware and software design of the intelligent spray dust reduction system is completed.Practice shows that the introduction of error back propagation algorithm to adjust the fuzzy control parameters can better adapt to the underground environment.The optimized spray pressure not only saves underground water,but also exerts the best dust reduction effect.
