基于LABVIEW的旋转机构测控系统设计

Design of Measurement and Control System Applied to Rotation Mechanism Based on LabView

针对发动机环形燃烧室试验测试的任务要求,设计了一套基于LabView开发环境下的测试系统和一套基于PLC控制技术的控制系统;在控制系统中,通过硬件的搭建、软件功能的实现和故障风险的预防处理,实现了旋转机构的控制;在测试系统中,利用LabView的控件开发了多种软件功能,丰富了测控系统的数据处理和显示功能,并且在软件界面上实现了友好的人机交互;利用OPC通讯方式,使LabView与PLC之间建立了数据交互,从而实现了两个系统之间命令的发送与信息的接收;经试验结果表明:该测控系统已达到预期设计效果。

In order to meet the requirement of annular combustor test,a measurement system based on LabView environment and a con-trol system based on PLC control technology was designed.For the control system,rotation control was achieved through hardware estab-lishment,software achievement and risk prevention.For the measurement system,data management and display ability of the system was enriched through a variety of software functions developed based on LabView,and friendly human-machine interface realized in software.In method of OPC network communication,the system achieved data interaction between LabView and PLC,so that the order and information could be transferred between two system.The test result shows that the system achieved the anticipated purpose.
