【摘要】 该文将虚拟仪器应用于动态压力标定系统,使用具有预触发功能的双通道同步数据采集装置,很好地解决了标准源信号与被校信号同步获取的问题。将COM技术开发的仪器驱动与上层的VB界面联合使用,使得校准操作灵活。实验结果表明该系统比传统校准设备可扩展性增强,系统精度提高。更多还原

【Abstract】 In this paper,the virtual instrument technique is used for the dynamic pressure data acquisition,processing and display in a dynamic pressure standardizing system.And by using the graphic language Labview,we design the driving program and the program front panel that is convenient for the customers.The acquisition system is applied to the dynamic pressure standardizing system and the experimental results show that the system can achieve the high speed data acquisition processing,real-time display and ideal standardizing effect.更多还原
