在很多工况下振动机械需要在工作过程中具有宽频谱、高振强的振动性能,为破解高振强状态下难以安全运行的测控技术瓶颈,研发LabVIEW测控系统,通过试验分析振强变化规律及导致振动机械运行不安全因素,利用传感检测的振动信号放大处理后,通过数据采集卡输入到上位机,经LabVIEW程序的处理后,在采集卡输出并控制变频器,从而控制振动机的振强特性变化规律,在可控范围内进行高效、安全地工作;试验和记录表明该系统对振动机的高振强性能具有实时有效的测控效果。
In many working conditions, vibrating machinery needs wide spectrum and high vibration performance in the working process. In order to solve the bottleneck of monitoring and control technology that is difficult to operate safely in high vibration condition, LabVIEW is developed to test and control the system. Through analyzing the law of vibration variation and leading to vibration machinery Operation unsafe factors, the use of sensing the vibration signal detection amplification, the data acquisition card input to the host computer, the LabVIEW program processing, the capture card output and control of the inverter, thereby controlling the vibrating machine vibration characteristics change Law and work efficiently and safely within the controllable range. Experiments and records show that the system has a real-time and effective measurement and control effect on the high vibration performance of vibrating machine.
