1、带式输送机监测系统摘要:带式输送机由其性能的优越性被广泛应用于矿山、港口、工厂生产等领域,其有别于其它运输机器的特点是运输距离长、输送速度快、输送量大,可对多种类型的物料进行连续运输。带式输送机作为连续工作的设备,若一旦出现打滑、跑偏、纵向撕裂等故障,将迫使企业停止生产,大大降低了生产效率,严重时会导致人员伤亡和机器报废。所以,为减少不必要的经济损失和人员伤亡,对带式输送机监测系统进行研究是非常重要的。本设计阐述了对带式输送机进行故障诊断的目的和意义,简述了带式输送机的基本结构和工作原理,论述了带式输送机的故障机理,提出了新的监测
2、原理和方法。最后,完成对监测系统总体方案的设计,在硬件方面由实际情况和监测原理选择合适的传感器,通过分析比较选择光电传感器完成对各个故障信号的采集,然后,由输送机结构尺寸和监测需要,对传感器的安装位置进行选择。由传感器收集到的信号进行初步采集后,传入数据采集卡,经过处理后使其成为工控机易于接收的信号,通过组态王软件,达到故障报警、实时显示、生成报表、打印、报表存储等目的。本文设计出的基于组态王软件带式输送机监测系统,通过调试运行可知,系统界面显示信息简洁明了,同时对故障情况能够达到实时监测显示,方便技术人员对运行状态进行分析,当有
