摘要:: 目的：为降低测量仪器系统误差噪声干扰的影响，准确测量X射线机电源电阻，设计一套X射线机电源电阻测量程序。方法：在信号注入法测电阻的基础上，利用LabVIEW软件和NI公司生产的信号调理模块，设计电源内阻测量程序，该程序可产生稳定的正弦激励电流，并对响应电压、响应电流以及相位差进行测量，进而得到X射线机电源电阻值。结果：经系统测试可知，该测量程序可以对X射线机电源电阻进行一段时间内的连续测量，得到的电源电阻均值更接近实际状况。结论：该测量程序能够准确测量X射线机电源电阻，为准确测量X射线机电源电阻提供了一种新的方法和思路。【关键词】X射线机；电源电阻；LabVIEW

Abstract:: Objective To design a set of X-ray machine power supply resistance measurement procedures for reducing the effects of the system errors of the measuring instruments and noise interference, and accurately measuring the power supply resistance of the X-ray machine. Methods Based on the signal injection method to measure resistance, LabVIEW software and the signal conditioning module produced by NI were used to design a program for measuring the internal resistance of power supply. The designed program could not only generate stable sinusoidal excitation current, but also measure response voltage, response current and phase difference, and then the power supply resistance of the X-ray machine was obtained. Results The system test showed that the measurement program could continuously measure the power supply resistance of the X-ray machine for a period of time, and that the average power supply resistance obtained was closer to the actual situation. Conclusion The proposed program can accurately measure the power supply resistance of the X-ray machine, providing a new method and idea for accurately measuring the power supply resistance of the X-ray machine.
