摘　　要：基于虚拟仪器技术并结合各种传感器,设计了籽棉残膜分离装置的测试系统,并将系统采集数据和四通道智能压力风速风量数据采集仪及手持式激光转速计测量的数据进行对比分析。试验结果表明:大、小滚筒转速采集数据的最大相对误差为0.68%,风速采集数据的最大相对误差为8.95%。系统测试精度满足对风速和转速的测量要求。In order to real-time and accurately obtain the multi-point wind speed of all the key regions and rotate speed of the big and small mesh rollers during running of the mesh roller-type unginned cotton and film remnant separator,the automatic monitor system was designed and developed based on virtual instrument technology combining with a variety of sensors.Finally,the value acquired by system was compared with the measured data of the handheld laser tachometer and the four-channel intelligent pressure data collecting instrument for wind speed and volume.Experimental results showed that the maximum relative error of rotate speed of the big and small mesh roller was 0.68%,and the maximum relative error of wind speed was 8.95%.The result indicated that the monitor system met the measurement requirements for collecting wind speed and rotate speed and the system was reasonable and practical.
