When the sample is measured by the Fourier transform infrared spectroscopy, the sample is irradiated with a continuous wavelength source, the sample molecules absorb light of certain wavelengths, and the unabsorbed light reaches the detector, and the signal is processed to obtain the spectrum of the sample to be tested. The acquired spectra are analyzed and processed.

The optical path difference between the two coherent lights passing through the Michaelson interferometer changes, and the light intensity measured by the detector changes accordingly. In the interferogram, the detector sends the obtained interference signal to a computer for mathematical processing of the Fourier transform, and reduces the interferogram to an infrared spectrum. Fourier transform infrared spectrometer has no dispersive components. The main components are light source, Michaelson interferometer, sample cell, detector, computer. The Michaelson interferometer is the core component of the Fourier transform infrared spectrometer. Its function is to The color light becomes interference light, and the Michaelson interferometer includes a moving mirror, a fixed mirror, and a beam splitter.

随着傅里叶变换红外光谱分析仪的应用范围越来越广，傅里叶变换红外光谱分析仪的使用环境呈现多样化及不确定性，包括振动干扰、温度变化及仪器倾斜放置等等，这些都将导致动镜和定镜不能垂直，使得分束器透射和反射的两束光不能重叠，傅里叶变换红外光谱分析仪输出红外信号参数进行分析时， 光谱的分辨率降低。With the wider application range of Fourier transform infrared spectroscopy analyzers, the environment of Fourier transform infrared spectroscopy analyzers is diversified and uncertain, including vibration interference, temperature changes and tilting of instruments. These will cause the moving mirror and the fixed mirror to be non-perpendicular, so that the two beams transmitted and reflected by the beam splitter cannot overlap, and the resolution of the spectrum is reduced when the Fourier transform infrared spectrum analyzer outputs the infrared signal parameters for analysis.

具体实施方式Detailed ways

如图2所示，一种傅里叶变换红外光谱分析仪的控制方法，包括步骤：As shown in FIG. 2, a control method of a Fourier transform infrared spectrum analyzer includes the following steps:

S100，获取红外信号启动参数的峰值。S100: Obtain a peak value of an infrared signal starting parameter.

当傅里叶变换红外光谱分析仪开机启动时，通过PID(Proportion Integral Derivative，比例积分微分)算法将音圈电机速度调节至1～10倍正常运行速度，音圈电机根据预设启动扫描频率运行，比如傅里叶变换红外光谱分析仪检测样品时运行为5Hz，那么启动阶段设置为4倍，即音圈电机以20Hz的频率运行，这样可采集40个信号参数，增加测量的时效性。由于启动阶段需通过调节电磁电机使激光信号和红外信号达到平稳输出，音圈电机的运行以时间为基准，然 后通过模数转换电路获取红外信号启动参数，如音圈电机半个周期内的脉冲数量、信号包络和红外信号的峰值等参数。When the Fourier transform infrared spectrum analyzer is started up, the voice coil motor speed is adjusted to 1 to 10 times the normal running speed by the PID (Proportion Integral Derivative) algorithm, and the voice coil motor operates according to the preset starting scanning frequency. For example, when the Fourier transform infrared spectrum analyzer detects the sample, the operation is 5 Hz, then the start-up phase is set to 4 times, that is, the voice coil motor runs at a frequency of 20 Hz, so that 40 signal parameters can be collected, and the timeliness of the measurement is increased. Since the laser signal and the infrared signal are smoothly outputted by adjusting the electromagnetic motor during the startup phase, the operation of the voice coil motor is based on time, and then the infrared signal starting parameter is obtained through the analog-to-digital conversion circuit, such as a pulse of the voice coil motor in a half cycle. Parameters such as number, signal envelope, and peak value of the infrared signal.

S300，当红外信号启动参数的峰值为预设最大峰值时，获取音圈电机的预设运行扫描频率以及激光信号启动参数。S300: When the peak value of the infrared signal starting parameter is the preset maximum peak value, the preset running scanning frequency of the voice coil motor and the laser signal starting parameter are obtained.

音圈电机控制信号的扫描周期，电磁电机是调节动镜与定镜的垂直度，当动镜与定镜相互垂直时，输出的红外信号值达到最大，输出的红外信号值最大的点，即为动镜与定镜的垂直点，启动阶段找出最佳的启动控制点即动镜与定镜垂直点后，将音圈电机设置为正常运行。The scanning period of the voice coil motor control signal, the electromagnetic motor is to adjust the verticality of the moving mirror and the fixed mirror. When the moving mirror and the fixed mirror are perpendicular to each other, the output infrared signal value reaches the maximum, and the output infrared signal value is the largest point, that is, For the vertical point of the moving mirror and the fixed mirror, after starting the stage to find the best starting control point, that is, the vertical point of the moving mirror and the fixed mirror, set the voice coil motor to normal operation.

当傅里叶变换红外光谱分析仪内部温湿度发生变化时，定镜与动镜的垂直度将发生变化，致使输出的红外信号和激光干涉信号发生变化，激光信号的包络或脉冲发生变化时，也说明动镜与定镜的垂直度发生了变化。When the internal temperature and humidity of the Fourier transform infrared spectroscopy change, the perpendicularity of the fixed mirror and the moving mirror will change, causing the output infrared signal and laser interference signal to change, and the envelope or pulse of the laser signal changes. It also shows that the verticality of the moving mirror and the fixed mirror has changed.

S700，将温湿度数据实时值与温湿度数据的预设值进行比较，并将激光信号运行参数与激光信号启动参数之差与预设差值进行比较。S700 compares the real-time value of the temperature and humidity data with the preset value of the temperature and humidity data, and compares the difference between the laser signal operating parameter and the laser signal starting parameter with the preset difference.

通过将温湿度数据实时值与温湿度数据的预设值进行比较，激光信号运行参数与激光信号启动参数之差与预设差值进行比较，可以反映动镜与定镜的垂直度是否发生了变化。By comparing the real-time value of the temperature and humidity data with the preset value of the temperature and humidity data, the difference between the laser signal operating parameter and the laser signal starting parameter is compared with the preset difference, which can reflect whether the verticality of the moving mirror and the fixed mirror have occurred. Variety.

S900，当温湿度数据实时值等于温湿度数据的预设值，且激光信号运行参数与激光信号启动参数之差等于预设差值时，输出红外信号运行参数。S900: When the real-time value of the temperature and humidity data is equal to the preset value of the temperature and humidity data, and the difference between the laser signal operating parameter and the laser signal starting parameter is equal to the preset difference, the infrared signal operating parameter is output.

当温湿度数据实时值等于温湿度数据的预设值，且激光信号运行参数与激光信号启动参数之差等于预设差值时，说明此时动镜与定镜相互垂直，则输出红外信号运行参数。When the real-time value of the temperature and humidity data is equal to the preset value of the temperature and humidity data, and the difference between the laser signal operating parameter and the laser signal starting parameter is equal to the preset difference, it indicates that the moving mirror and the fixed mirror are perpendicular to each other, and the output infrared signal is operated. parameter.

The difference is compared with the preset difference; when the real-time value of the temperature and humidity data is equal to the preset value of the temperature and humidity data, and the difference between the laser signal operating parameter and the laser signal starting parameter is equal to the preset difference, the infrared signal operating parameter is output, such that It can ensure that the running mirror and the fixed mirror are perpendicular to each other during operation, and the infrared signal of the output is improved.

当红外信号启动参数的峰值不为预设最大峰值时，说明启动时，动镜与定镜不是相互垂直，需要对启动阶段进行校准，通过控制电磁电机的运转，以调节动镜与定镜的垂直度，至动镜与定镜相互垂直。When the peak value of the infrared signal starting parameter is not the preset maximum peak, it indicates that the moving mirror and the fixed mirror are not perpendicular to each other when starting, and it is necessary to calibrate the starting phase to control the operation of the electromagnetic motor to adjust the moving mirror and the fixed mirror. The verticality is perpendicular to the mirror and the mirror.

其中，根据电磁电机控制算法得到电磁电机控制参数的步骤具体可以包括：The step of obtaining the electromagnetic motor control parameter according to the electromagnetic motor control algorithm may specifically include:

电磁电机控制算法采用1024个调节等级，两个电磁电机共1024*1024个调节等级，如果按照等级顺序进行处理将耗费大量的时间，所以需要进行快速寻找调节，方法是采用两个循环进行调节，第一个循环为粗调，找出符合条件的红外信号启动参数的峰值所处区域范围，然后在该区域范围内进行微调，找出对应的电磁电机控制参数。The electromagnetic motor control algorithm adopts 1024 adjustment levels, and the two electromagnetic motors have a total of 1024*1024 adjustment levels. If processing in the order of ranks will take a lot of time, it is necessary to perform quick search and adjustment. The method is to adjust by two cycles. The first cycle is a coarse adjustment to find the range of the peak of the starting parameter of the infrared signal that meets the condition, and then fine-tuning within the range to find the corresponding electromagnetic motor control parameters.
