BRIEF DESCRIPTION OF THE DRAWINGS

[0050] Figure 1 This is a schematic diagram of the present invention. DETAILED DESCRIPTION

[0051] like Figure 1 As shown, the carbon dioxide concentration monitoring system based on infrared monitoring includes a monitoring center, which is communicatively connected to a data acquisition module, a data analysis module, a data correction module, a data processing module, and a data alarm monitoring module;

[0052] The data acquisition module is used to collect infrared parameters and environmental parameters of the target area in real time;

[0053] The data analysis module is used to process the infrared parameters of the target area, generate an infrared spectrum, and establish a carbon dioxide concentration change curve;

[0054] The data correction module is used to analyze the impact of environmental parameters on the infrared spectrum, and correct the infrared spectrum according to the analysis results to obtain the actual infrared spectrum of the region;

[0055] The data processing module is used to process the regional infrared actual spectrum to obtain a carbon dioxide concentration curve;

[0056] The data alarm monitoring module is used to visualize the carbon dioxide concentration curve and monitor in real time whether the carbon dioxide concentration in each sub-area is abnormal. If abnormal, an alarm signal is generated.

[0057] The data acquisition module is used to collect infrared parameters and environmental parameters of the target area in real time. The specific process includes:

[0058] The target area is all areas where carbon dioxide concentration is monitored;

[0059] Divide the target area into several sub-areas of the same spatial size, record the number of obtained sub-areas as q, and label each sub-area as i, i = 1, 2, 3, ..., q, where i is an integer;

[0060] Infrared monitoring points are set in each sub-area, and infrared spectrum sensors are set in the infrared monitoring points to collect infrared parameters and environmental parameters at the infrared monitoring points in real time;

[0061] It should be further explained that, in a specific implementation process, the infrared spectrum sensor emits infrared light of different wavelengths through the target sub-area for infrared monitoring;

[0062] The infrared parameters include infrared light intensity and acquisition time;

[0063] The intensity of infrared light is recorded as Hq;

[0064] The acquisition time is recorded as t;

[0065] The environmental parameters include temperature, air pressure and water vapor content;

[0066] Record the temperature as F;

[0067] The air pressure value is recorded as Pa;

[0068] The water vapor content is recorded as Sn.

[0069] The data analysis module is used to process the infrared parameters of the target area, generate an infrared spectrum, and establish a carbon dioxide concentration change curve. The specific process includes:

[0070] According to the infrared parameters monitored by the infrared monitoring points in the sub-region, infrared spectrum parameters are obtained, and a regional infrared spectrum map is generated. The regional infrared spectrum maps of each sub-region are combined to obtain a corresponding infrared spectrum map set;

[0071] The infrared spectrum parameters are absorption peak position and absorption peak intensity;

[0072] The absorption peak position refers to the infrared wavelength corresponding to the maximum degree of infrared absorption of carbon dioxide in the infrared spectrum. The wavelength value corresponding to the absorption peak position is recorded as a specific wavelength, recorded as Bc;

[0073] The absorption peak intensity refers to the intensity of infrared light absorbed under a specific wavelength of infrared light, which is recorded as Xd. The acquisition time is correlated with the absorption peak intensity;

[0074] The horizontal axis of the regional infrared spectrum is the infrared wavelength, and the vertical axis is the absorption intensity of carbon dioxide;

[0075] It should be further explained that, in a specific implementation process, the absorption intensity of carbon dioxide is obtained based on the monitored infrared light intensity and the intensity of the infrared light itself.

[0076] The data correction module is used to analyze the impact of environmental parameters on the infrared spectrum, and correct the infrared spectrum according to the analysis results to obtain the actual regional infrared spectrum. The specific process includes:

[0077] Establish two-dimensional coordinate systems of time with respect to temperature, pressure and water vapor content respectively;

[0078] Generate regional temperature change curves, regional air pressure change curves, and regional water vapor content change curves based on the temperature values, air pressure values, and water vapor content collected in real time at infrared monitoring points;

[0079] Mapping the generated regional temperature change curve, regional air pressure change curve, and regional water vapor content change curve into a two-dimensional coordinate system;

[0080] Set standard environmental range;

[0081] The standard environmental range includes a standard temperature range, a standard air pressure range and a standard water vapor range;

[0082] The standard temperature range is recorded as (F1, F2);

[0083] The standard air pressure interval is recorded as (Pa1, Pa2);

[0084] The standard water vapor content interval is recorded as (0, Sn1);

[0085] When the temperature value, air pressure value and standard water vapor content corresponding to the same time belong to the standard environment range, the regional infrared spectrum corresponding to the time is the actual infrared spectrum of the region;

[0086] It should be further explained that, in a specific implementation, when the real-time collected temperature value falls within the standard temperature range, the real-time collected air pressure value falls within the standard air pressure range, and the real-time collected water vapor content falls within the standard water vapor content range, the regional infrared spectrum generated at the corresponding time is not affected by environmental factors related to temperature, air pressure, and water vapor content;

[0087] When any of the environmental factors, namely, the temperature value, the air pressure value, and the standard water vapor content, corresponding to the same time does not belong to the standard environmental range, the infrared spectrum of the region corresponding to the time is corrected;

[0088] When the temperature value does not belong to the standard temperature range, the temperature value affects the regional infrared spectrum, and the impact includes the degree of influence of the temperature value on the absorption peak intensity and the absorption peak position. The degree of influence of the temperature value on the absorption peak intensity is recorded as Q1, and the degree of influence of the temperature value on the absorption peak position is recorded as Q2;

[0089] Then Q1=α1*|FF c |, Q2=α2*|FF c |;

[0090] Among them, α1 and α2 are temperature influence coefficients. When F is less than F1, F c =F1, and α1 and α2 are negative. When F is greater than F2, F c =F2, and the signs of α1 and α2 are positive;

[0091] When the air pressure value does not belong to the air pressure-temperature interval, the air pressure value affects the regional infrared spectrum, and the influence includes the degree of influence of the air pressure value on the absorption peak intensity and the absorption peak position. The degree of influence of the air pressure value on the absorption peak intensity is recorded as P1, and the degree of influence of the air pressure value on the absorption peak position is recorded as P2;

[0092] Then P1=β1*|Pa-Pa c |, P2=β2*|Pa-Pa c |;

[0093] Among them, β1 and β2 are pressure influence coefficients. When Pa is less than Pa1, Pa c =Pa1, and β1 and β2 are negative. When Pa is greater than Pa2, Pa c =Pa2, and the signs of β1 and β2 are positive;

[0094] When the water vapor content does not fall within the standard water vapor content range, the water vapor content has an impact on the regional infrared spectrum. The impact refers to the degree of impact of the vapor content on the absorption peak intensity, and the degree of impact of the water vapor content on the absorption peak intensity is recorded as S1.

[0095] Then S1=γ1*|Sn-S c |;

[0096] Among them, γ1 is the water vapor influence coefficient. When Sn is greater than S1, S c =S1, and the sign of γ1 is positive;

[0097] Set the dynamic monitoring y factor and the dynamic monitoring x factor, record the dynamic monitoring y factor as YX1, and record the dynamic monitoring x factor as YX2;

[0098] but YX2=Q2+P2;

[0099] Correcting the regional infrared spectrum according to the dynamic monitoring y factor and the dynamic monitoring x factor;

[0100] The absorption peak intensity of the regional infrared spectrum is corrected according to the dynamic monitoring y factor to obtain the actual intensity Sd of the absorption peak;

[0101] Then Sd=YX1*Xd;

[0102] Correct the absorption peak position of the regional infrared spectrum according to the dynamic monitoring x factor to obtain the actual absorption peak position Sc;

[0103] Then Sc=YX2*Bc;

[0104] It should be further explained that, during the specific implementation process, the presence of water vapor in the air will absorb some infrared light, resulting in a decrease in the intensity of the infrared light. Changes in temperature and air pressure in the environment will affect the movement of carbon dioxide gas molecules, causing changes in the infrared light absorbed by the carbon dioxide gas molecules, thereby increasing the absorption intensity.

[0105] The actual regional infrared spectrum is generated by dynamically monitoring the correction of the absorption peak intensity of the regional infrared spectrum by the y factor and dynamically monitoring the correction of the absorption peak position of the regional infrared spectrum by the x factor.

[0106] The data processing module is used to process the regional infrared actual spectrum to obtain a carbon dioxide concentration curve. The specific process includes:

[0107] According to the actual intensity Sc of the absorption peak in the actual infrared spectrum of the region, the concentration value of carbon dioxide is obtained, which is recorded as Tc;

[0108] Then Tc=k*Sc;

[0109] Wherein, k is the conversion coefficient;

[0110] It should be further explained that, in the specific implementation process, the absorption intensity of carbon dioxide is proportional to the carbon dioxide concentration in the sub-region. The higher the absorption intensity, the higher the carbon dioxide concentration in the corresponding sub-region.

[0111] Establishing a two-dimensional coordinate system of carbon dioxide concentration in sub-regions with respect to time;

[0112] Generate a regional carbon dioxide concentration change curve based on the obtained carbon dioxide concentration values;

[0113] The generated carbon dioxide regional concentration change curve is mapped into a two-dimensional coordinate system.

[0114] The data alarm monitoring module is used to visualize the carbon dioxide concentration curve and monitor in real time whether the carbon dioxide concentration in each sub-area is abnormal. If abnormal, an alarm signal is generated. The specific process includes:

[0115] Set the carbon dioxide concentration threshold interval, recorded as (Nc1, Nc2);

[0116] Monitor the change of carbon dioxide concentration in the sub-area in real time. When the carbon dioxide concentration in the sub-area falls within the carbon dioxide concentration threshold interval (Nc1, Nc2), the carbon dioxide concentration is normal, and the sub-area is marked in yellow.

[0117] When the carbon dioxide concentration in a sub-area is lower than Nc1, the sub-area is marked green, the carbon dioxide concentration is abnormal, a low concentration alarm signal is generated, and the low concentration alarm signal is transmitted to relevant staff for processing;

[0118] When the carbon dioxide concentration in a sub-area is higher than Nc2, the sub-area is marked in red, the carbon dioxide concentration is abnormal, a high concentration alarm signal is generated, and the high concentration alarm signal is transmitted to relevant staff for processing;

[0119] Generate a concentration distribution map of the target area based on the color marking of each sub-area;

[0120] It should be further explained that, during the specific implementation process, the concentration distribution map of the target area can intuitively and vividly reflect the carbon dioxide concentration and the real-time changes in carbon dioxide concentration.
