[0044] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0045] Based on this, the embodiment of the present invention provides a temperature measurement method under high pressure environment, referring to Figure 1 , Figure 1 It is a flow chart of a first embodiment of a temperature measurement method under a high pressure environment of the present invention.

[0046] In this embodiment, the temperature measurement method under high pressure environment includes:

[0047] Step S10: modulate the original monochromatic light signal to obtain at least two modulated light signals.

[0048] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a control computer, etc. The following takes the control computer as an example to illustrate this embodiment and the following embodiments.

[0049] It should be noted that traditional temperature measurement technology may cause inaccurate temperature measurement or data transmission interference due to high-voltage electric fields and electromagnetic interference. Some existing technologies can also achieve temperature measurement in high-voltage charge environments, such as optical fiber temperature measurement, infrared temperature measurement, etc. However, the cost of optical fiber temperature measurement technology is relatively high, and accurate temperature measurement can only be achieved after installation and testing by professionals. Infrared temperature measurement technology is affected by dust, humidity, temperature and other factors in the environment, and the accuracy of temperature measurement is relatively low.

[0050] Based on this, this embodiment analyzes the modulated light signal and the heat absorption signal passing through the area to be detected to obtain the temperature change value of the light signal after passing through the area to be detected, thereby reducing the impact of the high charge environment on the temperature measurement, and finally combining the temperature change value of the light signal and the historical temperature parameters of the area to determine the current temperature parameters of the area, thereby improving the accuracy of temperature measurement in a high-load environment and avoiding the technical problems of low accuracy and low efficiency in temperature measurement in a high-voltage charge environment in the prior art.

[0051] The original monochromatic light signal may be generated by a laser, or may be generated by other devices that can generate monochromatic light signals, and this embodiment does not impose any specific limitation on this.

[0052] Furthermore, the step of modulating the original monochromatic light signal to obtain at least two modulated light signals includes:

[0053] generating a first sinusoidal modulated current having a first angular frequency and a second sinusoidal modulated current corresponding to a second angular frequency, wherein the second angular frequency is greater than the first angular frequency;

[0054] The first sinusoidal modulation current and the second sinusoidal modulation current are respectively applied to a laser emitting device that emits the original monochromatic light signal to obtain a first modulated light signal and a second modulated light signal.

[0055] In a specific implementation, modulating the original monochromatic light signal refers to applying a sinusoidal modulation current of a first angular frequency to the laser, so that the frequency and intensity of the original monochromatic light signal are deflected to obtain a first modulated light signal, and applying a sinusoidal modulation current of a second angular frequency to the laser, so that the frequency and intensity of the original monochromatic light signal are deflected to obtain a second modulated light signal, wherein the second angular frequency is greater than the first angular frequency, specifically, the second angular frequency is twice the first angular frequency, thereby reducing the noise between the two modulated light signals and reducing the workload of subsequent signal processing.

[0056] Step S20: obtaining the thermal absorption signal of the two modulated light signals passing through the area to be detected.

[0057] In the field of optics, when a modulated light signal passes through a certain area, it will be affected by the temperature of the area and generate transition state energy, thereby changing some physical properties of the light signal. By detecting the spectral characteristics of the modulated light signal and the thermal absorption light signal, the influence of parameters such as the temperature and medium concentration of the area on the light signal can be effectively monitored, thereby measuring parameters such as the temperature and medium concentration of the area.

[0058] Step S30: Analyze the heat absorption signal and the modulated light signal using a preset temperature change analysis model to obtain a temperature change value between the two light signals and the corresponding heat signal.

[0059] The preset temperature change analysis model is used to detect the temperature change value between the thermal absorption signal and the modulated light signal. At the same time, the accuracy of temperature measurement based on the energy transition of a single light signal is not high. Especially when processing a single light signal, the baseline and the absorption line type will be fitted. If the fitting effect is not good, it will cause the signal-to-noise ratio to increase, thereby affecting the accuracy of temperature measurement.

[0060] Step S40: determining the current temperature parameter of the area to be detected according to the temperature change value and the historical temperature parameter.

[0061] Since the light signal will undergo energy transition when passing through the area to be detected, this transition energy will cause the light signal to undergo temperature change. Therefore, this embodiment measures the temperature change value between the two light signals and the corresponding thermal signals, and combines it with the historically measured temperature parameters to accurately determine the current temperature parameters of the area to be detected.

[0062] Further, determining the current temperature parameter of the area to be detected according to the temperature change value and the historical temperature parameter includes:

[0063] Extract the last measured temperature from the historical temperature parameters;

[0064] The current temperature parameter of the area to be detected is determined according to the sum of the last measured temperature and the temperature change value.

[0065] In a specific implementation, since the measured temperature data is stored in each temperature measurement cycle, after determining the temperature change of the light signal passing through the area to be detected, the current temperature parameters of the area to be detected can be accurately measured in combination with the last measured temperature.

[0066] This embodiment obtains at least two modulated light signals by modulating the original monochromatic light signal; obtains the heat absorption signal of the two modulated light signals passing through the area to be detected; analyzes the heat absorption signal and the modulated light signal through a preset temperature change analysis model to obtain the temperature change value between the two light signals and the corresponding heat signal; determines the current temperature parameter of the area to be detected according to the temperature change value and the historical temperature parameter, and obtains the temperature change value of the light signal after passing through the area to be detected by analyzing the modulated light signal and the heat absorption signal passing through the area to be detected, thereby reducing the impact of the high-charge environment on the temperature measurement, and finally determines the current temperature parameter of the area in combination with the temperature change value of the light signal and the historical temperature parameters of the area, thereby improving the accuracy of temperature measurement in a high-load environment and avoiding the technical problems of low accuracy and low efficiency in temperature measurement in a high-voltage charge environment in the prior art.

[0067] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 2 , step S30, comprising:

[0068] Step S301: obtaining a second harmonic peak ratio between the first heat absorption signal and the second heat absorption signal.

[0070] Step S303: querying the first absorption line intensity corresponding to the first thermal absorption signal and the second absorption line intensity corresponding to the second thermal absorption signal at the reference temperature.

[0071] Step S304: Calculate the temperature change value between the two light signals and the corresponding thermal signals according to the second harmonic peak ratio, the transition energy level difference, the first absorption line intensity, the second absorption line intensity and a preset constant.

[0072] It should be noted that the second harmonic peak ratio refers to the absorption signals of two absorption lines obtained after two laser beams pass through the measurement area at the same time along the same path. The peak values ​​of the absorption signals of the two absorption lines are compared, and the ratio of the peak values ​​of the two absorption line spectra is taken as the second harmonic peak ratio. In order to accurately obtain the intensities of the two absorption line spectra, this embodiment needs to calculate the second-order coefficient of the Fourier series of the transmitted light intensity of the thermal absorption light signal, and then compare the peak values ​​of the two absorption line spectra.

[0073] Further, the obtaining of the second harmonic peak ratio between the first heat absorption signal and the second heat absorption signal comprises:

[0074] Determine, by a spectrometer, a first absorption line intensity corresponding to the first thermal absorption signal and a second absorption line intensity corresponding to the second thermal absorption signal at a reference temperature;

[0075] A second harmonic peak ratio is generated according to the first absorption line intensity and the second absorption line intensity.

[0076] In a specific implementation, the calculation formula for the second harmonic peak ratio is:

[0077]

[0078] Where R is the second harmonic peak ratio, is the ratio of the light intensity of the center frequency of the second heat absorption signal to that of the first heat absorption signal, a is the modulation amplitude of the modulated light signal compared to the frequency of the original monochromatic light signal, is the second-order coefficient of the Fourier series of the transmitted light intensity corresponding to the second thermal absorption signal, is the second-order coefficient of the Fourier series of the transmitted light intensity corresponding to the first thermal absorption signal.

[0079] Furthermore, the calculation formula of the temperature change value is:

[0080]

[0081] Where T is the temperature change value, T0 is the reference temperature, S1(T0) is the first absorption line intensity at the reference temperature T0, S2(T0) is the second absorption line intensity at the reference temperature T0, E``2 is the low energy state energy of the transition, and E``1 is the high energy state energy before the transition. is the center frequency of the absorption line; h is Planck's constant, c is the speed of light, k is the Boltzmann constant, K is the ratio of the integral of the linear function of the first thermal absorption signal and the second thermal absorption signal, It is the ratio of the light intensity of the center frequency of the first thermal absorption signal and the second thermal absorption signal.

[0082] This embodiment obtains the second harmonic peak ratio between the first heat absorption signal and the second heat absorption signal; determines the transition energy level difference between the first heat absorption signal and the second heat absorption signal; queries the first absorption line intensity corresponding to the first heat absorption signal and the second absorption line intensity corresponding to the second heat absorption signal at the reference temperature; calculates the temperature change value between the two light signals and the corresponding heat signals according to the second harmonic peak ratio, the transition energy level difference, the first absorption line intensity, the second absorption line intensity and the preset constant, and calculates the temperature change value of the heat absorption signal after the modulated light signal passes through the detection area through the pre-constructed temperature change analytical model, thereby reducing the impact of the high-voltage charge environment on the temperature measurement and improving the temperature measurement effect. .
