Intelligent monitoring of stacker reclaimer for circular coal yard using LiDAR technology

在圆形煤场内,堆取料机工作时的机械故障会直接影响堆取料机的安全运行。为保证堆取料机安全稳定工作,提出应用LiDAR技术的圆形煤场堆取料机智能监控方法。依据堆取料机的基本结构,对堆取料机运行方式以及运行特点展开分析;根据分析结果在堆取料机上设置监测点,结合LiDAR设备完成堆取料机运行数据的采集;基于采集的数据建立圆形煤场堆取料机的自动监控模型,并对模型训练优化;最后将获取的堆取料机运行数据输入模型中,通过模型输出实现圆形煤场堆取料机的智能监控。验证结果表明:使用该方法进行圆形煤场堆取料机智能监控,在监控数据量为3000个时,监控的误报率及漏报率分别为0.5%、1.8%,监控耗时为0.5 s。

In the circular coal yard,the mechanical failure of the stacker reclaimer would directly affect the safe operation of the stacker reclaimer.In order to ensure the safe and stable operation of the stacker reclaimer,an intelligent monitoring method for the stacker reclaimer in a circular coal yard using LiDAR technology was proposed.According to the basic structure of the stacker reclaimer,the operation mode and operation characteristics of the stacker reclaimer were analyzed;monitoring points were set up on the stacker reclaimer according to the analysis results,and the operation data collection of the stacker reclaimer was completed in combination with the LiDAR equipment.The automatic monitoring model of the circular coal yard stacker reclaimer was established based on the data collected,and the model training was optimized.Finally,the obtained stacker reclaimer operation data was put into the model,and the intelligent monitoring of the circular coal yard stacker reclaimer was realized through the model output.The verification results showed that using this method for intelligent monitoring of the circular coal yard stacker reclaimer,when the monitoring data volume was 3000,the false alarm rate and missed alarm rate were 0.5%and 1.8%respectively,and the monitoring time was 0.5 seconds.
