[0002] At present, solid oxide electrolytic cells can efficiently convert electrical energy into hydrogen, providing a feasible approach for clean and green hydrogen energy production. As an efficient energy medium, hydrogen can be used for fuel cell power generation, fuel storage and industrial applications, contributing to reducing carbon emissions and the use of fossil fuels. However, solid oxide electrolytic cells operate under high temperatures and extreme environments, and their performance may be affected by various factors, such as material instability, gas leakage, changes in electrode catalytic activity, etc. Gas leakage in solid oxide electrolytic cells is a serious problem because it may trigger fires, endanger human health, reduce electrolysis efficiency, and shorten the performance and lifespan of the electrolytic cell. In related technologies, sensors are usually inserted into the electrolytic cell to detect whether the electrolytic cell leaks gas. However, such a method will affect the normal operation of the electrolytic cell. Summary of the Invention

[0010] In this embodiment, the detection component is used to detect the electrolytic cell, so that the detection component can detect the electrolytic cell. The detection component includes a laser emission component, a collection component, a Raman spectrometer, and a data processing component. The laser emission component can emit laser light towards the electrolytic cell. The laser light irradiates the first gas on the peripheral side of the electrolytic cell, causing the laser photons to interact with the molecules near the electrolytic cell, resulting in changes in the vibration and rotation states of the molecules, and then generating Raman scattered light, that is, the laser generates Raman scattering. The collection component can collect the first parameter of the laser after Raman scattering, thereby realizing the collection of the parameters of the Raman scattered light. The Raman spectrometer is respectively connected to the laser emission component and the collection component to realize the connection between the Raman spectrometer and the laser emission component and the collection component respectively, so that the Raman spectrometer can receive the first parameter collected by the collection component and obtain the first spectrogram according to the first parameter, thereby generating the first spectrogram, that is, the Raman spectrogram, according to the received first parameter. The data processing component is connected to the Raman spectrometer and is used to determine the airtightness of the electrolytic cell according to the first spectrogram and the preset spectrogram, so that the data processing component can compare the first spectrogram with the preset spectrogram of the known gas, and then determine whether the first gas on the peripheral side of the electrolytic cell contains the gas leaked from the electrolytic cell. If it can be detected that the first gas contains the gas leaked from the electrolytic cell, it can be determined that a leak has occurred in the electrolytic cell. In this application, by using the detection component to emit laser light to the peripheral side of the electrolytic cell and detecting the first parameter of the laser after Raman scattering generated by the interaction of the laser with the gas on the peripheral side of the electrolytic cell to detect the airtightness of the electrolytic cell, compared with the method of inserting a sensor into the interior of the electrolytic cell for detection, this application does not require inserting a sensor into the electrolytic cell for detection, especially in the case where the electrolytic cell needs to be kept closed, so it will not interfere with the normal operation of the electrolytic cell.

[0011] In some embodiments of the present invention, the collection component includes a first cable and a collection part. One end of the first cable is electrically connected to the Raman spectrometer; the collection part is electrically connected to the other end of the first cable, and the detection end of the collection part faces the electrolytic cell.

One end of the first cable is electrically connected to the Raman spectrometer to realize the installation of the first cable, and the collection part is electrically connected to the other end of the first cable to realize the installation of the collection part, so that the Raman spectrometer can receive the first parameter collected by the collection part. The detection end of the collection part faces the electrolytic cell, so that the first detection part can collect the first parameter of the laser after Raman scattering near the electrolytic cell.

[0013] In some embodiments of the present invention, there is a first preset distance between the laser emission component and the electrolytic cell.

[0014] In this embodiment, there is a first preset distance between the laser emission component and the electrolytic cell, so that the irradiation range of the laser emission on the electrolytic cell can be adjusted, facilitating the expansion of the detection range of the electrolytic cell and avoiding the interference of the laser on the normal operation of the electrolytic cell due to the too-close distance between the laser emission component and the electrolytic cell.

[0015] In some embodiments of the present invention, the number of the acquisition components is multiple, and the multiple acquisition components are located on the circumferential side of the electrolytic cell.

[0016] In this embodiment, the number of the acquisition components is multiple, and the multiple acquisition components are located on the circumferential side of the electrolytic cell. By arranging the multiple acquisition components around the cell, the multiple acquisition components can detect different positions of the electrolytic cell, thereby improving the accuracy of the detection of the airtightness of the electrolytic cell.

[0017] Specifically, the multiple acquisition components include an acquisition part, a second acquisition part, and a third acquisition part. The acquisition part is located on one side of the cathode of the electrolytic cell, and thus can detect the airtightness of the cathode side of the electrolytic cell. The second acquisition part is located on one side of the anode of the electrolytic cell, and thus can detect the airtightness of the anode side of the electrolytic cell. The third acquisition part is located on one side of the electrolyte of the electrolytic cell, and thus can detect the airtightness of one side of the electrolyte of the electrolytic cell.

[0018] In some embodiments of the present invention, the Raman spectrometer includes a spectrometer and a detector. The spectrometer is used to separate the Stokes line and the anti-Stokes line in the first parameter of the laser after Raman scattering; the detector is connected to the spectrometer, and the detector is used to receive the Stokes line and the anti-Stokes line and determine the first spectrogram according to the Stokes line and the anti-Stokes line.

[0019] In this embodiment, the Raman spectrometer includes a spectrometer and a detector. The spectrometer is used to separate the Stokes line and the anti-Stokes line in the first parameter of the laser after Raman scattering, so as to eliminate the interference between the Stokes line and the anti-Stokes line and facilitate the acquisition of a clear and pure scattered spectral signal. The detector is connected to the spectrometer to realize the installation of the detector. The detector is used to receive the Stokes line and the anti-Stokes line. The Stokes line and the anti-Stokes line respectively correspond to the decrease and increase in the frequency of the scattered photons. By measuring the intensity and frequency changes of these two rays, the first spectrogram can be obtained. The generation of the first spectrogram is realized through the spectrometer and the detector, so as to determine whether the electrolytic cell leaks by using the first spectrum.

[0020] In some embodiments of the present invention, the detection component further includes an alarm component and a monitoring component. The alarm component is connected to the Raman spectrometer and is used to give an alarm when the electrolytic cell leaks; the monitoring component is connected to the alarm component and is used to display the alarm information.

Furthermore, the detection component can provide real-time monitoring, can promptly detect the gas leakage in the electrolytic cell, helps to take emergency measures to prevent potential safety problems, and can then remind the staff to quickly take measures to avoid the deterioration of the leakage situation, thus ensuring the personal safety of the staff. It can also prevent the spread of the leakage situation, thereby preventing the further expansion of the accident. The monitoring component is connected to the alarm component and is used to display the alarm information to enable the installation of the monitoring component. When there is a gas leakage, the alarm information can be displayed, facilitating the staff to promptly understand the leakage situation of the electrolytic cell.

[0022] In some embodiments of the present invention, the alarm component includes a sound alarm and a light alarm. The sound alarm can give a sound alarm when the electrolytic cell leaks, and / or the light alarm can give a light alarm when the electrolytic cell leaks.

[0023] In this embodiment, the alarm component includes a sound alarm and a light alarm. The sound alarm can give a sound alarm when the electrolytic cell leaks. By using the sound alarm to give an alarm when there is a gas leakage, the staff can quickly understand that the electrolytic cell leaks, and thus can quickly take corresponding measures to handle the leakage of the electrolytic cell. The light alarm can give a light alarm when the electrolytic cell leaks. By using the light alarm to give an alarm when there is a gas leakage, it is convenient for the operator to understand the leakage situation of the electrolytic cell, and it can also enable the staff to understand the alarm information in a noisy environment or at a relatively long distance, improving the reliability and timeliness of the alarm.

[0024] According to the second aspect of the present invention, a detection method for an electrolytic cell is provided. The detection method includes: controlling the laser emission component to emit laser towards the electrolytic cell, the laser irradiating the first gas on the peripheral side of the electrolytic cell, and the laser generating Raman scattering; controlling the acquisition component to acquire the first parameter of the laser after Raman scattering; controlling the Raman spectrometer to obtain the first spectrogram according to the first parameter; and determining the airtightness of the electrolytic cell according to the first spectrogram and the preset spectrogram.

[0025] In this embodiment, the detection method is used for an electrolytic cell, so that the electrolytic cell can be detected. The laser emission component is controlled to emit laser light to the electrolytic cell. The laser light irradiates the first gas on the periphery of the electrolytic cell, and Raman scattering is generated by the laser. The laser light irradiates the first gas on the periphery of the electrolytic cell, causing the laser photons to interact with the molecules near the electrolytic cell, resulting in changes in the vibration and rotation states of the molecules, and then generating Raman scattered light, that is, Raman scattering is generated by the laser. The acquisition component can acquire the first parameter of the laser after Raman scattering. The acquisition component is controlled to acquire the first parameter of the laser after Raman scattering, so as to realize the acquisition of the parameters of the Raman scattered light. The Raman spectrometer is controlled to obtain the first spectrogram according to the first parameter, so that the first spectrogram can be generated according to the received first parameter, that is, the Raman spectrogram. According to the first spectrogram and the preset spectrogram, the airtightness of the electrolytic cell is determined. The first spectrogram can be compared with the preset spectrogram of the known gas, and then it can be determined whether the first gas on the periphery of the electrolytic cell contains the gas leaked from the electrolytic cell. If it can be detected that the first gas contains the gas leaked from the electrolytic cell, it can be determined that a leak has occurred in the electrolytic cell. In this application, by emitting laser light to the periphery of the electrolytic cell and detecting the first parameter of the laser after Raman scattering generated by the interaction between the laser and the gas on the periphery of the electrolytic cell, the airtightness of the electrolytic cell is detected. Compared with the method of inserting a sensor into the interior of the electrolytic cell for detection, this application does not require inserting a sensor into the electrolytic cell for detection, especially in the case where the electrolytic cell needs to be kept closed, so it will not interfere with the normal operation of the electrolytic cell.

[0026] In some embodiments of the present invention, after determining the airtightness of the electrolytic cell according to the first spectrogram and the preset spectrogram, the detection method further includes: determining the gas type and gas concentration of the second gas leaked from the electrolytic cell in the case where the electrolytic cell leaks.

[0027] In this embodiment, after determining the airtightness of the electrolytic cell according to the first spectrogram and the preset spectrogram, in the case where the electrolytic cell leaks, the gas type and gas concentration of the second gas leaked from the electrolytic cell are determined, so that the gas type and concentration of the gas leaked from the electrolytic cell can be accurately detected, and then it can help the staff quickly judge the situation and degree of the leak. By accurately detecting the gas type and concentration of the leak, false alarms or missed alarms can be avoided, and the personal safety of the staff can be guaranteed. After the electrolytic cell leaks, an alarm that can detect the gas type and concentration of the leak has the advantages of high accuracy, timeliness, high safety, convenient maintenance, and high reliability.

[0028] In some embodiments of the present invention, controlling the Raman spectrometer to obtain the first spectrogram according to the first parameter includes: obtaining the Stokes line and the anti-Stokes line in the first parameter of the laser after Raman scattering; obtaining the first spectrogram according to the Stokes line and the anti-Stokes line.

[0029] In this embodiment, the Stokes line and the anti-Stokes line in the first parameter of the laser after Raman scattering are obtained; thus, the interference between the Stokes line and the anti-Stokes line can be eliminated, so as to obtain a clear and pure scattered spectral signal. Thus, an accurate first spectrogram can be obtained according to the Stokes line and the anti-Stokes line, and further, the accuracy of subsequent confirmation of whether the electrolytic cell leaks can be ensured.

[0030] In some embodiments of the present invention, the Stokes line and the anti-Stokes line in the first parameter of the laser after Raman scattering are obtained; according to the Stokes line and the anti-Stokes line, obtaining a first spectrogram includes: controlling a spectrometer to separate the Stokes line and the anti-Stokes line; sending the separated Stokes line and anti-Stokes line to a detector; controlling the detector to detect the light intensity and frequency of the Stokes line and the anti-Stokes line; and determining the first spectrogram according to the light intensity and frequency.

[0031] In this embodiment, controlling the spectrometer to separate the Stokes line and the anti-Stokes line, and sending the separated Stokes line and anti-Stokes line to the detector, so that the detector can analyze the Stokes line and the anti-Stokes line. Controlling the detector to detect the light intensity and frequency of the Stokes line and the anti-Stokes line, and the Stokes line and the anti-Stokes line respectively correspond to the decrease and increase of the frequency of scattered photons. By measuring the intensity and frequency changes of these two rays, a first spectrogram can be obtained.

[0032] In some embodiments of the present invention, determining the airtightness of the electrolytic cell according to the first spectrogram and a preset spectrogram includes: obtaining the preset spectrogram; comparing the first spectrogram and the preset spectrogram to obtain a comparison result; and obtaining the airtightness of the electrolytic cell according to the comparison result.

[0033] In this embodiment, obtaining the preset spectrogram, and the preset spectrogram can be obtained from a standard spectral library of known gases. Comparing the first spectrogram and the preset spectrogram, the first spectrogram is a Raman scattering spectrum, that is, comparing the Raman scattering spectrum and the standard spectrum of the known gas, which can be carried out in the following way: obtaining Raman scattering spectrum data and the preset spectrum data of the known gas, importing the two spectral data into the same graph or data table, and overlapping them together. Comparing the shapes of the two spectra and the positions of the characteristic peaks to determine whether there are matching peaks. If there are matching peaks, their relative intensities and peak shapes can be further compared to determine whether there are deviations. If there are no deviations, it can be determined that the known gas exists in the first gas on the periphery of the electrolyte. If the gas is the gas existing in the electrolytic cell, it can be determined that the electrolytic cell has leaked, and further, the airtightness of the electrolytic cell can be judged.

[0034] In some embodiments of the present invention, before controlling the laser emission component to emit laser light towards the electrolytic cell, the detection method further includes: controlling the operation of the electrolytic cell.

[0035] In this embodiment, before controlling the laser emission component to emit laser light towards the electrolytic cell, controlling the normal operation of the electrolytic cell, by controlling the startup of the electrolytic cell, can ensure that the device operates in a safe state and avoid potential risks and accidents caused by abnormal startup. Controlling the startup of the electrolytic cell can ensure that the device operates accurately according to the preset procedures and conditions, thereby ensuring the accuracy and reliability of the detection results. By pre-controlling the startup of the electrolytic cell, the time for device debugging and troubleshooting can be shortened, and the efficiency of the entire detection process can be improved. Pre-controlling the electrolytic cell can timely detect potential problems and take corresponding preventive measures to avoid equipment failures during operation and ensure the smooth progress of the detection process.

[0036] In some embodiments of the present invention, controlling the laser emission component to emit laser light towards the electrolytic cell includes: controlling the laser emission end of the laser emission component to emit laser light towards the side of the electrolytic cell with an anode, the side with a cathode, and the side with an electrolyte.

[0037] In this embodiment, controlling the laser emission end of the laser emission component to emit laser light towards the side of the electrolytic cell with an anode, the side with a cathode, and the side with an electrolyte can comprehensively detect various parts of the electrolytic cell, thereby ensuring the integrity and accuracy of the detection results. Using laser as the excitation light source is convenient for quickly obtaining Raman scattering spectrum data at various positions of the electrolytic cell, thereby shortening the detection time and improving the detection efficiency. Irradiating laser light at the positions of the anode, cathode, and electrolyte of the electrolytic cell will not cause damage to the electrolytic cell itself and will not affect the normal operation of the electrolytic cell. At the same time, analyze the gas components on the anode, cathode, and electrolyte sides of the electrolytic cell to obtain more comprehensive detection information.

[0038] In some embodiments of the present invention, before controlling the laser emission component to emit laser light towards the electrolytic cell, the detection method further includes: calibrating the Raman spectrometer.

[0039] In this embodiment, before controlling the laser emission component to emit laser light towards the electrolytic cell, that is, before detecting the airtightness of the electrolytic cell, calibrating the Raman spectrometer can ensure that the spectrometer can accurately measure, ensuring its accuracy and reliability. It can also eliminate the errors existing in the Raman spectrometer itself and the influence of external environmental factors on the instrument, thereby ensuring the accuracy of the measurement, facilitating quickly determining whether there is air leakage in the electrolytic cell, and improving work efficiency. Calibrating the spectrometer can also extend its service life and maintain a good working state.

[0040] In some embodiments of the present invention, after determining the airtightness of the electrolytic cell according to the first spectrogram and the preset spectrogram, the detection method further includes: controlling an alarm component to give an alarm when it is detected that the electrolytic cell leaks.

[0041] In this embodiment, controlling the alarm component to give an alarm when it is detected that the electrolytic cell leaks can remind the operator to pay attention to safety and avoid dangerous accidents. The operator can timely discover the leakage problem of the electrolytic cell, prevent the leakage situation from deteriorating, and cause greater losses. The alarm function of controlling the alarm component can also remind the operator to take necessary preventive measures, such as closing the valve, reducing the flow rate, etc., to prevent the leakage situation from further deteriorating, timely repair the electrolytic cell, extend the service life of the equipment, and improve the operation efficiency of the equipment.

[0042] In some embodiments of the present invention, after determining the composition and concentration of the gas, the detection method further includes: controlling the alarm component to give an alarm when it is detected that the gas concentration of the second gas is greater than a preset concentration threshold.

[0043] In this embodiment, controlling the alarm component to give an alarm when it is detected that the gas concentration of the second gas is greater than the preset concentration threshold can remind the operator to take immediate action to ensure safety. It is convenient to timely discover and control the leakage of the electrolytic cell, prevent accidents from occurring, reduce safety risks, and avoid possible losses. Furthermore, it can monitor the gas concentration of the electrolytic cell in real time to ensure the safety of the production process.

[0044] According to the third aspect of the present invention, a detection device is provided. The detection device includes: a first processing module, configured to control a laser emitting component to emit a laser towards the electrolytic cell, the laser irradiates the first gas on the periphery of the electrolytic cell, and Raman scattering is generated by the laser; a second processing module, configured to control an acquisition component to acquire a first parameter of the laser after Raman scattering; a third processing module, configured to obtain a first spectrogram according to the first parameter; a fourth processing module, configured to determine the airtightness of the electrolytic cell according to the first spectrogram and the preset spectrogram.

[0045] In this embodiment, the first processing module is used to control the laser emission component to emit laser light towards the electrolytic cell. The laser light irradiates the first gas on the periphery of the electrolytic cell, and Raman scattering is generated by the laser. When the laser light irradiates the first gas on the periphery of the electrolytic cell, the laser photons interact with the molecules near the electrolytic cell, resulting in changes in the vibration and rotation states of the molecules, and then Raman scattered light is generated, that is, Raman scattering is generated by the laser. The second processing module is used to control the acquisition component to acquire the first parameter of the laser after Raman scattering, and control the acquisition component to acquire the first parameter of the laser after Raman scattering, so as to realize the acquisition of the parameters of the Raman scattered light. The third processing module is used to obtain the first spectrogram according to the first parameter; thus, the first spectrogram, that is, the Raman spectrogram, can be generated according to the received first parameter. The fourth processing module is used to determine the airtightness of the electrolytic cell according to the first spectrogram and the preset spectrogram. The first spectrogram can be compared with the preset spectrogram of the known gas, and then it can be determined whether the first gas on the periphery of the electrolytic cell contains the gas leaked from the electrolytic cell. If it can be detected that the first gas contains the gas leaked from the electrolytic cell, it can be determined that a leak has occurred in the electrolytic cell. In this application, by emitting laser light to the periphery of the electrolytic cell and detecting the first parameter of the laser after Raman scattering generated by the interaction between the laser and the gas on the periphery of the electrolytic cell, the airtightness of the electrolytic cell is detected. Compared with the method of inserting a sensor into the interior of the electrolytic cell for detection, this application does not require inserting a sensor into the electrolytic cell for detection, especially in the case where the electrolytic cell needs to be kept closed, so it will not interfere with the normal operation of the electrolytic cell.

Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the protection scope of the present invention.

[0060] Next, refer to Figures 1 to 6 Describe the detection component 100, detection method, detection device 400, electronic device 500, and storage medium according to some embodiments of the present invention.

[0061] In an embodiment of the present application, as Figure 1 shown, a detection component 100 is provided for detecting an electrolytic cell 170. The detection component 100 includes a laser emission component 110, a collection component 120, a Raman spectrometer 130, and a data processing component 140. The laser emission component 110 can emit laser light towards the electrolytic cell 170, and the laser light irradiates a first gas on the peripheral side of the electrolytic cell 170, generating Raman scattering; the collection component 120 can collect a first parameter of the laser light after Raman scattering; the Raman spectrometer 130 is respectively connected to the laser emission component 110 and the collection component 120, and is used to obtain a first spectrogram according to the first parameter; the data processing component 140 is connected to the Raman spectrometer 130, and is used to determine the airtightness of the electrolytic cell 170 according to the first spectrogram and a preset spectrogram.

[0062] In this embodiment, the detection component 100 is used to detect the electrolytic cell 170, so that the detection component 100 can detect the electrolytic cell 170. The detection component 100 includes a laser emission component 110, a collection component 120, a Raman spectrometer 130, and a data processing component 140. The laser emission component 110 can emit laser light towards the electrolytic cell 170, and the laser light irradiates the first gas on the peripheral side of the electrolytic cell 170, causing the laser photons to interact with the molecules near the electrolytic cell 170, resulting in changes in the vibration and rotation states of the molecules, and then generating Raman scattered light, that is, the laser generates Raman scattering. The collection component 120 can collect the first parameter of the laser after Raman scattering, thereby realizing the collection of the parameters of the Raman scattered light. The Raman spectrometer 130 is respectively connected to the laser emission component 110 and the collection component 120 to realize the connection between the Raman spectrometer 130 and the laser emission component 110 and the collection component 120 respectively, so that the Raman spectrometer 130 can receive the first parameter collected by the collection component 120 and obtain the first spectrogram according to the first parameter, thereby generating the first spectrogram according to the received first parameter, that is, the Raman spectrogram. The data processing component 140 is connected to the Raman spectrometer 130 and is used to determine the airtightness of the electrolytic cell 170 according to the first spectrogram and the preset spectrogram, so that the data processing component 140 can compare the first spectrogram with the preset spectrogram of the known gas, and then determine whether the first gas on the peripheral side of the electrolytic cell 170 contains the gas leaked from the electrolytic cell 170. If it can be detected that the first gas contains the gas leaked from the electrolytic cell 170, it can be determined that a leak has occurred in the electrolytic cell 170. In this application, by using the detection component 100 to emit laser light towards the peripheral side of the electrolytic cell 170 and detecting the first parameter of the laser after Raman scattering generated by the interaction between the laser and the gas on the peripheral side of the electrolytic cell 170 to detect the airtightness of the electrolytic cell 170, compared with the method of inserting a sensor into the interior of the electrolytic cell 170 for detection, this application does not require inserting a sensor into the electrolytic cell 170 for detection, especially in the case where the electrolytic cell 170 needs to be kept closed, so it will not interfere with the normal operation of the electrolytic cell 170.

[0063] Specifically, in Figure 1 , A is the anode of the electrolytic cell 170, B is the electrolyte, C is the cathode of the electrolytic cell 170, Gas and gas are other gases in the electrolytic cell 170 except hydrogen and oxygen, H2O is water, O2 is oxygen, e - is an electron, H2 is hydrogen, H + is a hydrogen ion.

[0064] Specifically, the first cable 122 is an optical fiber cable. The laser emitting component 110 is connected to the acquisition component 124 through the optical fiber cable. The acquisition component 124 is a Raman probe. After receiving the laser emitted by the laser emitting component 110, it irradiates the sample, then acquires the reflected signal and transmits it to the Raman spectrometer 130.

[0065] Specifically, the first parameter is the Raman scattered light generated after the interaction between the laser and the molecules in the first gas, that is, the Raman spectrum. The principle of the Raman spectrum is based on Raman scattering, that is, when a laser photon interacts with a molecule, the energy of the photon changes slightly and is scattered back. This Raman spectrum contains information about the molecule, including its chemical composition and structure. The Raman spectrum is a non-invasive technique. Therefore, when the detection component 100 of the present application detects the electrolytic cell 170, it is not necessary to insert a sensor into the electrolytic cell 170 system, so it will not interfere with the normal operation of the electrolytic cell 170. The Raman spectrum has high selectivity for different gases, so that the detection component 100 can accurately identify hydrogen, oxygen and other gas components without using multiple sensors. The Raman spectrum is very sensitive to changes in gas concentration and can detect minute gas leaks. The Raman spectrum can provide real-time monitoring, can detect gas leaks in a timely manner, helps to take emergency measures to prevent potential safety problems. The Raman spectrum can simultaneously detect multiple gas components and can accurately identify different gases, including hydrogen, oxygen and other gases that may be present in the fuel cell, and this can detect complex electrolytic cell 170 systems.

[0066] Specifically, a Raman spectrometer 130 with high resolution and high sensitivity is used for detection, so that low-concentration gases can be detected.

[0067] Specifically, the electrolytic cell 170 area is irradiated with a laser light source. The laser can excite the molecular vibration of the first gas on the periphery of the electrolytic cell 170 to generate a scattered spectrum.

[0068] Specifically, the optical fiber probe or appropriate optical component of the acquisition component 120 is installed near the electrolytic cell 170 to collect the Raman scattered signal, ensuring that the probe or optical component will not affect the normal operation of the electrolytic cell 170.

[0092] In some other embodiments of the present application, a detection method for an electrolytic cell is provided, as Figure 3 shown. The detection method includes:

[0093] S202, controlling the laser emission component to emit laser towards the electrolytic cell. The laser irradiates the first gas on the peripheral side of the electrolytic cell, and Raman scattering is generated by the laser;

[0095] S206, controlling the Raman spectrometer to obtain a first spectrogram according to the first parameter;

[0096] S208, determining the airtightness of the electrolytic cell according to the first spectrogram and a preset spectrogram.

[0097] In this embodiment, the detection method is used for an electrolytic cell, so that the electrolytic cell can be detected. The laser emission component is controlled to emit laser light towards the electrolytic cell. The laser light irradiates the first gas on the periphery of the electrolytic cell, and Raman scattering occurs to the laser light. When the laser light irradiates the first gas on the periphery of the electrolytic cell, the laser photons interact with the molecules near the electrolytic cell, resulting in changes in the vibration and rotation states of the molecules, and then Raman scattered light is generated, that is, Raman scattering occurs to the laser light. The acquisition component can acquire the first parameter of the laser light after Raman scattering. The acquisition component is controlled to acquire the first parameter of the laser light after Raman scattering, so as to realize the acquisition of the parameters of the Raman scattered light. The Raman spectrometer is controlled to obtain the first spectrogram according to the first parameter, so that the first spectrogram can be generated according to the received first parameter, that is, the Raman spectrogram. According to the first spectrogram and the preset spectrogram, the airtightness of the electrolytic cell is determined. The first spectrogram can be compared with the preset spectrogram of the known gas, and then it can be determined whether the first gas on the periphery of the electrolytic cell contains the gas leaked from the electrolytic cell. If it can be detected that the first gas contains the gas leaked from the electrolytic cell, it can be determined that a leak has occurred in the electrolytic cell. In this application, by emitting laser light to the periphery of the electrolytic cell and detecting the first parameter of the laser light after Raman scattering generated by the interaction between the laser light and the gas on the periphery of the electrolytic cell to detect the airtightness of the electrolytic cell, compared with the method of inserting a sensor into the interior of the electrolytic cell for detection, this application does not require inserting a sensor into the electrolytic cell for detection, especially in the case where the electrolytic cell needs to be kept closed, so it will not interfere with the normal operation of the electrolytic cell.

[0098] This embodiment provides a detection method, as Figure 4 shown, the detection method further includes:

[0099] S302. Control the laser emission component to emit laser light towards the electrolytic cell. The laser light irradiates the first gas on the periphery of the electrolytic cell, and Raman scattering occurs to the laser light;

[0100] S304. Control the acquisition component to acquire the first parameter of the laser light after Raman scattering;

[0101] S306. Control the Raman spectrometer to obtain the first spectrogram according to the first parameter;

[0102] S308. Determine the airtightness of the electrolytic cell according to the first spectrogram and the preset spectrogram;

[0103] S310. In the case where the electrolytic cell leaks, determine the gas type and gas concentration of the second gas leaked from the electrolytic cell.

[0104] In this embodiment, after determining the airtightness of the electrolytic cell based on the first spectrogram and the preset spectrogram, in the case of leakage of the electrolytic cell, the gas type and gas concentration of the second gas leaking from the electrolytic cell are determined, so that the gas type and concentration of the leaked electrolytic cell can be accurately detected, and then the staff can be helped to quickly judge the situation and degree of leakage. By accurately detecting the gas type and concentration of the leakage, false alarms or missed alarms can be avoided, and the personal safety of the staff can be guaranteed. After the electrolytic cell leaks, the alarm that can detect the gas type and concentration of the leaked gas has the advantages of high accuracy, timeliness, high safety, convenient maintenance, and high reliability.

[0105] Specifically, by detecting whether the electrolytic cell leaks air, the interaction between laser photons and molecules in the sample causes changes in the vibration and rotation states of the molecules, and then Raman scattered light is generated. By measuring and analyzing the frequency changes of the Raman scattered light, information about the molecules in the sample can be obtained, including its chemical composition, structure, and concentration, etc.

[0106] In some embodiments of the present invention, controlling the Raman spectrometer to obtain the first spectrogram according to the first parameter includes: obtaining the Stokes line and the anti-Stokes line in the first parameter of the laser after Raman scattering; obtaining the first spectrogram according to the Stokes line and the anti-Stokes line.

[0107] In this embodiment, the Stokes line and the anti-Stokes line in the first parameter of the laser after Raman scattering are obtained; thus, the interference between the Stokes line and the anti-Stokes line can be eliminated, so as to obtain a clear and pure scattered spectral signal. Thus, an accurate first spectrogram can be obtained according to the Stokes line and the anti-Stokes line, and then the accuracy of subsequent confirmation of whether the electrolytic cell leaks can be guaranteed.

[0108] In some embodiments of the present invention, obtaining the Stokes line and the anti-Stokes line in the first parameter of the laser after Raman scattering; obtaining the first spectrogram according to the Stokes line and the anti-Stokes line includes: controlling the spectrometer to separate the Stokes line and the anti-Stokes line; sending the separated Stokes line and anti-Stokes line to the detector; controlling the detector to detect the light intensity and frequency of the Stokes line and the anti-Stokes line; determining the first spectrogram according to the light intensity and frequency.

[0109] In this embodiment, controlling the spectrometer to separate the Stokes line and the anti-Stokes line and sending the separated Stokes line and anti-Stokes line to the detector so that the detector can analyze the Stokes line and the anti-Stokes line. Controlling the detector to detect the light intensity and frequency of the Stokes line and the anti-Stokes line, the Stokes line and the anti-Stokes line respectively correspond to the decrease and increase of the frequency of the scattered photons. By measuring the intensity and frequency changes of these two rays, the first spectrogram can be obtained.

[0110] In some embodiments of the present invention, determining the airtightness of an electrolytic cell according to a first spectrogram and a preset spectrogram includes: obtaining the preset spectrogram; comparing the first spectrogram with the preset spectrogram to obtain a comparison result; and obtaining the airtightness of the electrolytic cell according to the comparison result.

[0111] In this embodiment, to obtain the preset spectrogram, the preset spectrogram can be obtained from a standard spectrogram library of known gases. Comparing the first spectrogram with the preset spectrogram, where the first spectrogram is a Raman scattering spectrogram, that is, comparing the Raman scattering spectrogram with the standard spectrogram of the known gas, can be carried out in the following way: obtaining Raman scattering spectrogram data and the preset spectrogram data of the known gas, importing the two spectrogram data into the same graph or data table, and overlapping them. Comparing the shapes of the two spectrograms and the positions of the characteristic peaks to determine whether there are matching peaks. If there are matching peaks, their relative intensities and peak shapes can be further compared to determine whether there are deviations. If there are no deviations, it can be determined that the known gas exists in the first gas on the periphery of the electrolyte. If this gas is the gas present in the electrolytic cell, it can be determined that the electrolytic cell has leaked, and thus the airtightness of the electrolytic cell can be judged.

Using laser as the excitation light source facilitates the rapid acquisition of Raman scattering spectral data at various positions of the electrolytic cell, thereby shortening the detection time and improving the detection efficiency. Irradiating laser light at the positions of the anode, cathode, and electrolyte of the electrolytic cell will not cause damage to the electrolytic cell itself, nor will it affect the normal operation of the electrolytic cell. At the same time, the gas components on the anode, cathode, and electrolyte sides of the electrolytic cell are analyzed to obtain more comprehensive detection information.

[0116] In some embodiments of the present invention, before controlling the laser emission component to emit laser light to the electrolytic cell, the detection method further includes: calibrating the Raman spectrometer.

[0117] In this embodiment, before controlling the laser emission component to emit laser light to the electrolytic cell, that is, before detecting the airtightness of the electrolytic cell, calibrating the Raman spectrometer can ensure that the spectrometer can accurately measure, ensuring its accuracy and reliability. It can also eliminate the errors existing in the Raman spectrometer itself and the influence of external environmental factors on the instrument, thereby ensuring the accuracy of the measurement, facilitating the rapid determination of whether there is air leakage in the electrolytic cell, and improving the work efficiency. Calibrating the spectrometer can also extend its service life and maintain a good working state.

[0118] In some embodiments of the present invention, after determining the airtightness of the electrolytic cell according to the first spectrogram and the preset spectrogram, the detection method further includes: controlling the alarm component to give an alarm when it is detected that the electrolytic cell leaks.

[0119] In this embodiment, when it is detected that the electrolytic cell leaks, controlling the alarm component to give an alarm can remind the operator to pay attention to safety and avoid dangerous accidents. The operator can timely discover the leakage problem of the electrolytic cell, prevent the leakage situation from deteriorating and causing greater losses. The alarm function of controlling the alarm component can also remind the operator to take necessary preventive measures, such as closing the valve, reducing the flow rate, etc., to prevent the leakage situation from further deteriorating, timely repair the electrolytic cell, extend the service life of the equipment, and improve the operation efficiency of the equipment.

[0120] In still some other embodiments of the present invention, after determining the composition and concentration of the gas, the detection method further includes: controlling the alarm component to give an alarm when it is detected that the gas concentration of the second gas is greater than the preset concentration threshold.

[0121] In this embodiment, when it is detected that the gas concentration of the second gas is greater than the preset concentration threshold, the alarm component is controlled to give an alarm, which can remind the operator to take immediate action to ensure safety. This helps to promptly detect and control the leakage of the electrolytic cell, prevent accidents from occurring, reduce safety risks, and avoid possible losses. Furthermore, it can monitor the gas concentration of the electrolytic cell in real time to ensure the safety of the production process.
