By detecting the gas content, we can understand the progress of the reaction process, help optimize production parameters, and improve production efficiency and product quality. The gas generated in the process of producing compound fertilizer contains multiple gases. If the QEPAS (Quartz-Enhanced Photoacoustic Spectroscopy) method is directly used to detect the content of various gases in the gas to be tested, the absorption peaks of various gases will overlap, resulting in cross interference, and ultimately low detection accuracy. Summary of the invention

Based on the chemical reactions occurring in the compound fertilizer production process, the types of gases that may be contained in the gas to be tested are obtained and recorded as all the types of gases in the gas to be tested.

[0012] Preferably, the obtaining of the degree of interference of each absorption peak of each gas comprises the following specific methods:

[0013] Obtain the wavelength range of all absorption peaks of each gas in the gas to be measured, and for any absorption peak of any gas, record the remaining absorption peaks that intersect with the wavelength range of the absorption peak among all absorption peaks of each gas in the gas to be measured as interference absorption peaks of the absorption peak; obtain the intersection of the absorption peak and each of its interference absorption peaks in the wavelength range, and record it as the interference wavelength range of the interference absorption peak of the absorption peak;

[0014] The proportion of the union of all interfering wavelength ranges of the absorption peak that interfere with the absorption peak in the wavelength range of the absorption peak is taken as the degree of interference of the absorption peak.

[0015] Preferably, the wavelength range of all absorption peaks of each gas in the gas to be measured is obtained through the HITRAN database.

[0016] Preferably, the obtaining of the clarity of each absorption peak of each gas comprises the following specific methods:

[0017] For any absorption peak of any gas, the difference between the mean amplitude within the wavelength range of the absorption peak and the mean amplitude within the interference wavelength range of each interfering absorption peak of the absorption peak is recorded as the difference between the absorption peak and each interfering absorption peak of the absorption peak; the ratio of the mean value of the difference between the absorption peak and all interfering absorption peaks of the absorption peak to the degree of interference of the absorption peak is taken as the clarity of the absorption peak.

[0018] Preferably, the specific method of screening out the target absorption peak of each gas includes:

[0019] For any gas, the clarity of all absorption peaks of the gas is obtained, and the absorption peak with the greatest clarity is recorded as the target absorption peak of the gas.

[0020] Preferably, the specific method of obtaining the preference degree of each wavelength in the target absorption peak of each gas includes:

[0021] A neighborhood range is preset, and any wavelength in the target absorption peak of any gas is recorded as the target wavelength, and all wavelengths in the preset neighborhood range of the target wavelength are taken as local wavelengths of the target wavelength; based on the difference between the amplitude corresponding to the target wavelength of the gas and the amplitude corresponding to each local wavelength of the target wavelength of the remaining gases, combined with the amplitude corresponding to the target wavelength of the gas to be measured, the preferred degree of the target wavelength is obtained.

When the absorption peak overlaps with the wavelength range of all the absorption peaks of the other gases, cross interference occurs, resulting in a decrease in the accuracy of detecting the gas content through the wavelength of the absorption peak. At the same time, when the difference between the gas and the other gases in the corresponding amplitude in the overlapping part is greater, it is more difficult to accurately obtain the characteristics of the gas through the absorption peak, so the target absorption peak of each gas is obtained based on this;

[0029] According to the amplitude corresponding to the wavelength in the target absorption peak of each gas and the amplitude corresponding to the other gases at the same wavelength, the best wavelength for detecting the content of each gas is screened out; within the wavelength range of any absorption peak of a gas, the larger the amplitude is, the more accurately the gas content can be detected by the QEPAS method, and in order to avoid the influence of other gases on the detection of gas content when detecting gas content, the difference in amplitude between each wavelength in the wavelength range of the target absorption peak of the gas and the same wavelength of the other gases is required, and the larger the difference is, the less the gas content detected at this wavelength will be affected by the other gases; according to the best wavelength for detecting the content of each gas, the content of each gas is obtained; thereby, the cross-interference between various gases in the gas to be measured is minimized, so as to accurately obtain the content of each gas in the gas to be measured.

[0033] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following is a detailed description of the data detection method for safe production of compound fertilizers based on cloud computing proposed by the present invention, its specific implementation method, structure, characteristics and effects, in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "another embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures or characteristics in one or more embodiments may be combined in any suitable form.

[0034] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0035] The specific scheme of a data detection method for safe production of compound fertilizers based on cloud computing provided by the present invention is described in detail below with reference to the accompanying drawings.

[0036] See also Figure 1, which shows a step flow chart of a data detection method for safe production of compound fertilizers based on cloud computing provided by an embodiment of the present invention, the method comprising the following steps:

[0037] Step S001: Acquire all types of gases in the gas to be tested.

[0038] It should be further explained that in the process of producing compound fertilizer, multiple chemical reactions are involved, and different chemical reactions and production conditions may affect the amount and type of gas generated. By detecting the gas content, the progress of the reaction process can be understood, which helps optimize production parameters, improve production efficiency and product quality. Therefore, this embodiment proposes a data detection method for safe production of compound fertilizers based on cloud computing, specifically detecting the content of various gases generated in the process of compound fertilizer production; therefore, it is first necessary to collect the gas generated during the production of compound fertilizers.

[0039] Specifically, at the reactor in the compound fertilizer production process, the gas generated in the compound fertilizer production process is collected through an air bag, and the collected gas is recorded as the gas to be tested. Based on the chemical reactions occurring in the compound fertilizer production process, the types of gases that may be contained in the gas to be tested are obtained and recorded as all the types of gases in the gas to be tested.

[0040] Step S002: According to the overlap between each gas and other gases in the wavelength range of the absorption peak, obtain the degree of interference of each absorption peak of each gas; according to the degree of interference of each absorption peak of each gas and the amplitude difference between the overlapping ranges, obtain the clarity of each absorption peak of each gas; according to the clarity of each absorption peak of each gas, screen out the target absorption peak of each gas.

[0041] It should be noted that this embodiment obtains the optimal wavelength for detecting various gases by analyzing the differences between the absorption peaks of the absorption spectra of various gases to improve the detection accuracy. The absorption spectrum refers to the spectrum generated by the absorption of photons by a substance and the transition from a low energy level to a high energy level, and the absorption peak refers to the phenomenon in spectroscopy that the absorption of electromagnetic radiation by a substance within a specific wavelength range reaches a peak, and different gases may show different numbers and characteristics of absorption peaks. In order to avoid the cross-interference caused by different types of gases when detecting the content of all types of gases, which reduces the detection accuracy, this embodiment analyzes the wavelength range of the absorption peaks of all types of gases that may be contained in the gas to be tested, and obtains the remaining absorption peaks that overlap with the absorption peak by analyzing the wavelength range of each absorption peak of each gas. According to the overlap of the absorption peak and the wavelength range of all absorption peaks of the remaining gases, the degree of cross-interference of each absorption peak of each gas is quantified, and the difference in amplitude between the absorption peak and the absorption peak with overlapping conditions is further obtained. The absorption peak can clearly obtain the index of gas content, and then the optimal wavelength range of the absorption peak is selected as the initial band range to improve the accuracy of detecting gas content.

[0042] Preferably, in one embodiment of the present invention, the wavelength range of all absorption peaks of each gas in the gas to be measured is obtained through the HITRAN database. Since the HITRAN database is well known to those skilled in the art, it will not be described in detail in this embodiment; for any absorption peak of any gas, the remaining absorption peaks that intersect with the wavelength range of the absorption peak among all absorption peaks of each gas in the gas to be measured are recorded as interference absorption peaks of the absorption peak; the intersection of the absorption peak and each of its interference absorption peaks in the wavelength range is obtained, and recorded as the interference wavelength range of the interference absorption peak of the absorption peak;

[0043] Furthermore, the proportion of the union of all interfering wavelength ranges of the absorption peak that interfere with the absorption peak in the wavelength range of the absorption peak is taken as the degree of interference of the absorption peak.

[0044] It should be noted that when the wavelength range of any absorption peak of any gas overlaps with the wavelength ranges of the absorption peaks of other gases, the overlapping part will be cross-interfered and the accuracy will be reduced. Therefore, the larger the proportion of the union of the interfering wavelength ranges of all interfering absorption peaks in the wavelength range of the absorption peak, the higher the interference to the absorption peak.

[0045] It should be further explained that, since the amplitudes of the absorption peaks of different gases are different in their wavelength ranges, and when the difference in amplitudes within the wavelength ranges of the absorption peaks of different gases is large, even if the wavelength ranges of their absorption peaks overlap, the absorption peak characteristics of different gases can still be clearly identified. Therefore, the absorption peak can be obtained based on the degree of interference on each absorption peak of each gas and the amplitude difference between the overlapping ranges to clearly obtain an indicator of the gas content.

[0046] Preferably, in one embodiment of the present invention, for any absorption peak of any gas, the difference between the mean amplitude within the wavelength range of the absorption peak and the mean amplitude within the interference wavelength range of each interference absorption peak of the absorption peak is recorded as the difference between the absorption peak and each interference absorption peak of the absorption peak; the ratio of the mean value of the difference between the absorption peak and all the interference absorption peaks of the absorption peak to the degree of interference of the absorption peak is taken as the clarity of the absorption peak;

[0047] Furthermore, for any gas, the clarity of all absorption peaks of the gas is obtained, and the absorption peak with the greatest clarity is recorded as the target absorption peak of the gas.

[0048] It should be noted that the clarity of the absorption peak indicates the degree to which the gas content can be clearly obtained through the absorption peak; therefore, the gas content can be more accurately obtained through the absorption peak with the greatest clarity, so the absorption peak with the greatest clarity is recorded as the target absorption peak of the gas to improve the accuracy of detecting the gas content.

[0049] At this point, the target absorption peaks of all gases are obtained.

[0050] Step S003: According to the amplitude corresponding to the wavelength in the target absorption peak of each gas and the corresponding amplitudes of other gases at the same wavelength, the preference degree of each wavelength in the target absorption peak of each gas is obtained, and according to the preference degree of each wavelength in the target absorption peak of each gas, the optimal wavelength for detecting the content of each gas is screened out.

[0051] It should be noted that the target absorption peak of the gas obtained through step S002 is a complete absorption peak, and the wavelength range of a complete absorption peak is too large. When detecting the content of each gas, only a specific wavelength is needed to detect the gas content. Therefore, in order to accurately detect the content of each gas, it is necessary to further select an optimal wavelength from the wavelength range of the target absorption peak of each gas to detect the gas content.

[0052] It should be further explained that within the wavelength range of any absorption peak of a gas, the larger the amplitude, the more accurate the gas content can be detected. In order to avoid the influence of other gases on the detection of gas content, the difference in amplitude between each wavelength in the wavelength range of the target absorption peak of the gas and the same wavelength of other gases is required. The larger the difference, the less the gas content detected at this wavelength will be affected by other gases. Therefore, this can be used as a basis to obtain the best wavelength for detecting gas content.

[0053] Optionally, in one embodiment of the present invention, a neighborhood range β is preset, and the specific value of β can be set by oneself in combination with the specific actual situation. This embodiment is not limited thereto. In this embodiment, β=10 is used for description, and any wavelength in the target absorption peak of any gas is recorded as the target wavelength, and all wavelengths in the preset neighborhood range of the target wavelength are taken as the local wavelengths of the target wavelength; according to the difference between the amplitude corresponding to the target wavelength of the gas and the amplitude corresponding to each local wavelength of the target wavelength of the other gases, combined with the amplitude corresponding to the target wavelength of the gas to be measured, the preferred degree of the target wavelength is obtained;

[0054] In one example, the difference between the amplitude corresponding to the target wavelength of the gas and the amplitude corresponding to each local wavelength of the target wavelength of the remaining gases is recorded as each interference factor of the target wavelength, and the product of the sum of all interference factors of the target wavelength and the amplitude corresponding to the target wavelength is taken as the preference degree of the target wavelength. The specific calculation formula is:

[0055]

[0056] Where Y v Indicates the preferred degree of the target wavelength of the vth gas in the gas to be measured; f v represents the amplitude corresponding to the target wavelength of the vth gas in the gas to be measured; m represents the number of gas types in the gas to be measured; n represents the number of local wavelengths of the target wavelength; F i,j It represents the amplitude of the i-th gas in the measured gas corresponding to the j-th local wavelength of the target wavelength; || represents the absolute value operation.

[0057] It should be noted that for any wavelength in any gas, the greater the difference between the amplitude corresponding to the wavelength and the amplitude of other gases at the wavelength, the less likely the characteristics obtained by the wavelength will be interfered by other gases. At the same time, the larger the amplitude corresponding to the wavelength, the more it can characterize the characteristics of the gas. Therefore The larger the value is, the more this wavelength should be used as the wavelength for detecting the gas. In this way, the best wavelength is selected from the wavelength range of the target absorption peak of each gas to accurately detect the content of each gas.

[0058] Preferably, in one embodiment of the present invention, for any gas, the preference level of each wavelength in the wavelength range of the target absorption peak of the gas is obtained, and the wavelength with the greatest preference level is used as the optimal wavelength for detecting the gas content.

[0059] Step S004: Obtain the content of each gas according to the optimal wavelength for detecting the content of each gas.

[0060] It should be noted that after obtaining the optimal wavelength for detecting the content of each gas in the gas to be tested through step S003, the content of each gas in the gas to be tested can be accurately detected by the QEPAS method, and the content of each gas in the gas to be tested can be uploaded to the cloud, and the cloud server can be used to detect whether there is any abnormality in the process of producing compound fertilizers.

[0061] Preferably, in one embodiment of the present invention, for any one gas, the optimal wavelength for detecting the gas content is obtained, and the wavelength of the laser is set to the optimal wavelength of the gas content, and the gas content is detected by the QEPAS method.

[0062] It should be noted that the laser is a device for detecting gas content using the QEPAS method, and the QEPAS method is a well-known prior art, so it will not be described in detail in this embodiment.

[0063] Furthermore, the content of each gas in the gas to be tested is obtained, and the content of each gas in the gas to be tested is uploaded to the cloud, and the cloud server is used to detect whether there is any abnormality in the process of producing compound fertilizers.

[0064] It should be noted that this embodiment analyzes the difference between the corresponding amplitudes of each gas in the gas to be measured at each wavelength, thereby minimizing the occurrence of cross-interference between various gases in the gas to be measured, and accurately obtaining the content of each gas in the gas to be measured.

[0066] At this point, this embodiment is completed.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the principles of the present invention should be included in the protection scope of the present invention.
