摘　　要：NFC适用于旋转状态下稳定的数据采集与无线交互,且其无源的特点使得采集端的设计更为小巧灵活,可避免旋转过程中测量系统的线路束缚和因偏轴对数据造成的严重误差。据此设计了一种基于NFC(ISO15693协议)的无源无线测量系统,采用旋转法对一种特制喷涂减阻材料的减阻率进行测量。测量过程中设置对照组并重复多次实验,分别得到恒定转速条件下减阻率随减阻涂层厚度的变化关系、恒定减阻涂层厚度条件下减阻率随转速的变化关系。通过对实验数据分析,表明本系统能够准确测量旋转状态下减阻材料的减阻率。NFC is suitable for stable data acquisition and wireless interaction in the rotating state,and its passive feature makes the design of the acquisition terminal more compact and flexible,which can avoid the line binding of the measurement system in the rotating process and the serious errors caused by off-axis data.A passive wireless measurement system based on NFC(ISO15693 protocol)is designed to measure the drag reduction rate of a special spray material by using rotating method.The control group is set and repeated for many times during the measurement process,and the relationship between the drag reduction rate and the thickness of the drag reduction coating is obtained under the condition of constant speed,and the relationship between the drag reduction rate and the speed is obtained under the condition of constant thickness of the drag reduction coating.Through the analysis of the experimental data,it is shown that the system can accurately measure the drag reduction rate of the drag reduction material in the rotating state.
