探讨一种基于PXI总线的织机经纱张力测试系统的运行效果.织机经纱张力测试系统由PXI主机、传感器、数据采集器、调理适配器及虚拟仪器软件组成,传感器采集主轴转角信号、主轴零位信号、经纱张力信号.介绍了测试系统的工作原理、测试方法,并对多台喷气织机的经纱张力进行了测试.结果表明,与传统的电阻应变仪及其他系统相比,该测试系统建立系统快、编程简单、可靠、系统抗干扰强、测量精确、通用性强.

Test System of Loom Warp Tension Based on PXI Bus

Operation effect of test system of loom warp tension based on PXI bus was discussed. Loom warp tension test system is made by PXI host machine, sensor, data acquisition, adapter and virtual instrument software. Sensor collects main shaft angle signal, main shaft null signal, warp tension signal. Working principle, test method were introduced, and warp tension of several air-jet loom was tested. The result shows that this test system has advantages of quick establishment, simple programming, good dependability, better anti-jamming, exact measure, and better applicability comparing with traditional strain gauge transducer and other system.
