摘要
为减少电液舵机的测试时间,减小测试对舵机的损伤,提高舵机的测试效率和精度,提出了以虚拟仪器为基础,设计了一套集机械、液压、电气以及计算机为一体的工业测控系统,硬件由工控机、PCI采集板卡、通讯总线、泵站和PLC控制柜、电气控制柜等组成,软件在LabWindows/CVI环境下编写,采用RTX实时系统、多线程处理和TDMS等核心处理方法,实现了对于某型电液舵机性能指标的自动化测试,试验表明系统运行稳定,测试结果准确可靠。
In order to reduce the test time of the electro-hydraulic steering engine,reduce the damage to the steering engine and improve the test efficiency and precision,it was designed a test system that contain mechanical,hydraulic,electrical and computer based on virtual Instrument.The hardware was composed of industrial computer,PCI board,communication bus,pump station,PLC and electrical control cabinet.The software is designed in LabWindows/CVI platform.RTX real-time system,multi-thread processing and TDMS and other core processing methods was used in test system.With this system,performance of the electro-hydraulic steering engine was tested automated.The application showed that the system run steadily with high system precision.
