摘要

在煤矿开采机械化水平不断提高下,需要采煤机结合实际工况进行调速控制,实现节能化升级.为此,先基于刮板输送机的负载预测开展采煤机调速控制系统的设计,然后参考小波神经网络应用构建刮板输送机负载的预测模型,采集电流数据为采煤机调速模型提供数据支持.其次,在明确不同负载下采煤机的调速范围后,合理利用Elman神经网络,完成采煤机的调速策略研究.最后,开展对应的工业性试验,试验数据显示采煤机调速控制具有较高精确度和较快响应速度,可满足矿采需要.

Abstract

With the continuous improvement of the mechanization level of coal mining,it is necessary to control the speed regulation of shearers according to the actual working conditions to achieve energy-saving upgrading.Therefore,based on the load prediction of scraper conveyors,the shearer speed regulation control system was designed,and then the load prediction model of scrapers was built with reference to the application of wavelet neural network,and data support was provided for the shearer speed regulation model with the collected current data.Secondly,after determining the speed regulation range of shearer under different loads,the Elman neural network was used rationally to complete the speed regulation strategy research of shearer.Finally,the corresponding industrial test was carried out,and the test data showed that the speed control of the shearer had higher accuracy and faster response speed,which can meet the needs of mining.
