摘要
针对某风洞试验任务需要进行大量压力测点测量的需要,利用USB4716数据采集卡和16点压力单元模块的结构形式,设计了一套实现多点远距离测量的数据采集系统。针对在试验过程中出现的试验数据异常现象进行了详细的分析,并给出了具体解决方案。该系统已经成功应用于风洞试验,并取得较好效果。
For acquiring pressure data in wind tunnel test, the data acquisition system which can achieve data with long distance and multi-sensors based on USB4716 card and sixteen-pressure modules is designed, and the abnormal data in test are analyzed and the material solution in the application is made. The system has been successfully applied to the test and achieved a good effect.
