【摘要】：圆管带式输送机具有空间转弯半径小,输送线路布置灵活、机架宽度小、输送倾角大等优点,在工业生产与散料输送领域扮演着重要的角色。由于圆管带式输送机的应用较晚,目前,对圆管带式输送机的研究较少,因此圆管带式输送机实验台的研究就显得尤为重要。东北大学与某企业共同设计制造了一台圆管带式输送机多功能实验台,本文将对圆管带式输送机多功能实验台的控制系统进行研究。根据圆管带式输送机多功能实验台控制系统设计需求,完成了对实验台控制系统的硬件选型。包括对输送机驱动装置的选型,保护装置的选型,张力检测装置的选型,驱动滚筒轴转矩转速检测装置的选型,PLC及相关硬件设备的选型。研究分析了模糊PID自整定控制系统在圆管带式输送机实验台驱动装置上的应用。通过MATLAB模糊工具箱和SIMULINK对所建立的模糊PID自整定控制系统进行了仿真和性能研究,并分析了仿真结果。在圆管带式输送机多功能实验台控制系统软件方面,建立了圆管带式输送机多功能实验台软起动、圆管带式输送机实验台综合保护、圆管带式输送机实验台驱动装置变频调速模糊自整定PID控制程序流程。选用组态软件组态王8.5为上位机监控软件平台,进行上位机监控系统的设计,编写了圆管带式输送机多功能实验台的上位机监控界面。通过对圆管带式输送机运行时托辊所受运行阻力的分析,为圆管带式输送机实验台设计了运行阻力测试系统。以USB4716多功能数据采集卡为测试系统核心,采集6个托辊上所受的垂直方向上的法向力和水平方向上的切向力,实现托辊受力的多路数据采集。上位机以美国国家仪器(NI)公司开发的LabVIEW8.5软件为平台开发了测试软件系统,该测试软件系统可同时测试圆管带式输送机运行时各托辊所受的切向力和法向力,共12路信号。测试软件系统具有数据采集、波形显示、数据存储、数据统计分析等功能。
