Description

TECHNICAL FIELD

[0001] The present application relates to the field of gas volume concentration calculation, and in particular to a gas volume concentration calculation method and related equipment. BACKGROUND

[0002] Gas volume concentration, usually referred to as gas concentration, is an important parameter of gas. For toxic and harmful gas, its concentration directly determines whether it is harmful to the human body or what degree of damage it causes. The volume concentration of gas is generally expressed in units of mg / m3. When measuring gas by infrared spectroscopy, the column concentration of gas is often measured, which refers to the gas concentration per unit area, usually expressed in units of mg / m3. That is, for the same volume concentration of gas, the shorter the length of the gas, the lower the column concentration of the gas, and the longer the length of the gas, the higher the column concentration of the gas. Conversely, for the same column concentration of gas, the corresponding volume concentration is not the same according to the length of the gas. 2

[0003] Therefore, it is still not possible to determine whether the target toxic and harmful gas has reached the concentration threshold that is harmful to the human body by measuring the column concentration of the gas. SUMMARY

[0033] Exemplary embodiments of the present application will be described in greater detail below with reference to the accompanying drawings. Although exemplary embodiments of the present application are shown in the drawings, it is understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present application can be more thoroughly understood, and so that the scope of the present application can be conveyed to those skilled in the art.

[0034] To solve the problem of lacking a more convenient and simple method for calculating gas volume concentration, an embodiment of the present application provides a gas volume concentration calculation method, as shown in Figure 1 The method comprises:

[0035] S101, obtaining first spectrum information and second spectrum information after passing through a first gas pool and a second gas pool in a same detection distance in a target space, wherein the first gas pool and the second gas pool are closed spaces in the target space, the first gas pool and the second gas pool are pre-charged with a same kind of pre-charged gas or vacuum, and the pre-charged gas is different from a target gas kind in the target space;

[0036] For example, as shown in Figure 2 The gas pool is composed of a closed cylinder, the cylinder contains infrared transmission windows at both ends, and the inside of the cylinder is sealed with a known concentration of gas. An embodiment of the present application sets two gas pools, a first gas pool and a second gas pool, in a target space, with lengths of L1 and L2 respectively, a gas kind of a gas cloud is β, a gas kind in the first gas pool and the second gas pool is ω, a gas volume concentration of the gas cloud is P, and gas volume concentrations in the first gas pool and the second gas pool are P1 and P2 respectively. The gas kind of the gas ω needs to be selected to be different from the kind of the gas β, and the two kinds of gas have different absorption peaks, so as to ensure that the concentration of the gas ω does not affect the measurement result of the gas β, and it is also necessary to ensure that the first gas pool and the second gas pool are closed spaces in the target space, so as to prevent the gas in the first gas pool and the second gas pool from exchanging with the gas in the target space to affect the measurement result.

[0037] S102, the volume concentration of the target gas is obtained based on the first spectral information and the second spectral information.

[0038] Exemplarily, the embodiment of the present application inserts two closed gas cells in the region to be measured by means of the spectral method, and calculates the volume concentration of the target gas, thereby solving the problem that the conventional method cannot measure the actual concentration of the gas in the open space.

[0039] By means of the technical solution, the gas volume concentration calculation method provided by the present application solves the problem that there is no more convenient and simple method for calculating the gas volume concentration. The first spectral information and the second spectral information after passing through the first gas cell and the second gas cell in the same detection distance in the target space are obtained, wherein the first gas cell and the second gas cell are closed spaces in the target space, the first gas cell and the second gas cell are pre-charged with the same kind of pre-charged gas or vacuum, and the pre-charged gas is different from the target gas in the target space in kind. The volume concentration of the target gas is obtained based on the first spectral information and the second spectral information. In the above solution, two gas cells of different lengths are arranged in the target space, the actual concentration of the gas is estimated based on the two gas cells of different lengths, the pre-charged gas is controlled to be different from the target gas in the target space in kind, so that the gas absorption peaks are different, and it is ensured that the concentration of the pre-charged gas does not affect the measurement result of the target gas, thereby solving the problem that the conventional method cannot measure the actual concentration of the gas.

[0040] In an embodiment, the first spectral information and the second spectral information are obtained based on an infrared spectrometer.

[0041] Exemplarily, the infrared spectral module can be a single-element detection module, and can also be a face array imaging detection module. The infrared spectral method is used to measure the gas column concentration C1 at the first gas cell and the gas column concentration C2 at the second gas cell. The values of C1 and C2 are directly measured by the instrument, and do not need to be calculated by the volume concentration of the gas. The infrared spectral method for measuring the gas column concentration usually adopts a calibration method, that is, the infrared spectral equipment is calibrated for the spectral absorption peak height of the β gas with different column concentrations (the concentration is known). During actual measurement, the measurement value of the gas column concentration is obtained by interpolating the calibration value according to the absorption peak.

[0042] Exemplarily, the embodiment of the present application is arranged in the area where the target gas cloud is generated after the first gas cell and the second gas cell are filled with gas or vacuumized. The first gas cell and the second gas cell are arranged in parallel in the axial direction and are directed to the direction of the infrared spectrum module. The infrared spectrum device and the calculation module are connected and started. The optical axis direction of the infrared spectrum module is adjusted by the scene image collected by the infrared spectrum device, so that the optical axis of the infrared spectrum module is parallel to the axial direction of the gas cell module. After the adjustment is completed, the gas column concentration is measured by the infrared spectrum module using the method described in the embodiment of the present application, and the measurement value of the gas column concentration is transmitted to the calculation module for calculation to obtain the volume concentration of the gas.

[0043] In an embodiment, the volume concentration of the target gas is obtained based on the first spectrum information and the second spectrum information, and includes:

[0044] determining the first gas column concentration of the first region based on the first spectrum information,

[0045] determining the second gas column concentration of the second region based on the second spectrum information;

[0046] determining the volume concentration of the target gas based on the first gas column concentration, the second gas column concentration, the preset length of the first gas cell and the preset length of the second gas cell.

[0047] Exemplarily, the gas column concentration C1 at the first gas cell is represented by the following formula:

[0048] C1=P(L-L1)

[0049] In the formula, P is the gas column concentration of the target gas β, L is the thickness of the target gas cloud, and L1 is the preset length of the first gas cell. Therefore, the gas column concentration of the first gas cell without the gas cell is P*L. When a gas cell is inserted into the first gas cell, and the gas in the gas cell is different from the target gas, it is considered that the gas thickness of the first gas cell is reduced by L1.

[0050] The gas column concentration C2 at the second gas cell is represented by the following formula, in which P is the gas column concentration of the target gas β, L is the thickness of the target gas cloud, and L2 is the preset length of the second gas cell:

[0051] C2=P(L-L2)

[0052] Exemplarily, the volume concentration of the target gas is determined based on the two expressions.

[0053] In one embodiment, the above-mentioned determining the volume concentration of the target gas according to the first gas column concentration, the second gas column concentration, the preset length of the first gas pool and the preset length of the second gas pool comprises:

[0054] determining a first difference value based on the difference between the first gas column concentration and the second gas column concentration;

[0055] determining a second difference value based on the difference between the preset length of the first gas pool and the preset length of the second gas pool;

[0056] determining the volume concentration of the target gas based on the ratio of the first difference value and the second difference value.

[0057] For example, the first gas column concentration expression minus the second gas column concentration expression is expressed as follows:

[0058] C1-C2=P(L2-L1)

[0059] Thus, the volume concentration of the target gas can be derived as follows:

[0060] P=(C1-C2) / (L2-L1)

[0061] In one embodiment, the difference between the cross-sectional areas of the first gas pool and the second gas pool is less than a preset minimum difference.

[0062] For example, by controlling the difference between the cross-sectional areas of the first gas pool and the second gas pool to be less than a preset minimum difference, the accuracy of the calculation is ensured.

[0063] In one embodiment, the lengths of the first gas pool and the second gas pool are different.

[0064] For example, by ensuring that the lengths of the first gas pool and the second gas pool are different, only the unknown quantity L in the two expressions is eliminated, and then the expression is transformed to obtain the volume concentration P of the target gas that we want to calculate.

[0065] In one embodiment, the distance between the first gas pool and the second gas pool is less than a preset distance.

[0066] For example, the distance between the first gas pool and the second gas pool is less than a preset distance, which can be considered as the volume concentration of the target gas outside the gas pool being close, thereby ensuring the stability of the measurement results and the calculation results.

[0067] Exemplarily, it is noted that the first gas pool and the second gas pool do not contain the target gas; the first gas pool and the second gas pool have infrared light transparent windows, the materials of the front and back windows of the first gas pool and the second gas pool are not specially limited, as long as they are suitable for the infrared spectrum device and can transmit infrared light of the corresponding wave band; the arrangement direction of the front and back windows of the first gas pool and the second gas pool is not specially limited, and can be perpendicular to the optical axis direction or at a certain angle; the lengths of L1 and L2 are known; the thickness L of the target gas cloud is unknown; the optical axis of the infrared spectrum device needs to be parallel to the first gas pool and the second gas pool, and passes through the front and back windows of the first gas pool and the second gas pool; the measurement times of C1 and C2 should be performed at the same time to ensure that the measurement conditions are similar. It can be understood that the embodiments of the present application can also use the method of multiple measurements to ensure the accuracy of the measurement results.

[0068] Exemplarily, the volume concentration and the column concentration are two units for describing the gas concentration. The unit of the volume concentration is usually mg / m 3 , which describes the mass of the gas molecules in a unit volume. The column concentration is directional, and the unit is usually mg / m 2 , which describes the mass of the gas molecules in a unit area, and can also be regarded as the product of the volume concentration and the length of the gas. The conversion relationship of the two units can be understood as follows:

[0069] Suppose there is a sealed container with a piston at the top, containing 100 mg of ω gas. In the initial state, the volume of the sealed container is 1 m 3 , and the height is 1 m, so the volume concentration P 初始 = 100 mg / m 3 . The direction of the column concentration is the height direction as shown in the figure, and the value is the product of the volume concentration and the length of the gas P 初始 × 1 m = 100 mg / m 2 .

[0070] When the sealed container is compressed by the piston, the volume of the sealed container in the compressed state is 0.5 m 3 , the height is 0.5 m, and the mass of the gas is still 100 mg. Then the volume concentration P 压缩 = 200 mg / m 3 can be calculated. The direction of the column concentration is the height direction as shown in the figure, and the value is the product of the volume concentration and the length of the gas P 压缩 × 0.5 m = 100 mg / m 2 .

[0071] The volume concentration is doubled after compression, but the column concentration does not change. Therefore, the column concentration and the volume concentration are two methods of describing the gas concentration from different aspects. When an infrared spectrum device measures the first gas cell and the second gas cell at the same time, the infrared radiation passes through the first gas cell and the second gas cell at the same time and is received by the infrared spectrum device. Since the beta gas and the omega gas are two completely different gases, when our device is measuring the beta gas, the concentration of the omega gas will not affect the measurement result of the beta gas. Similarly, when our device is measuring the omega gas, the concentration of the beta gas will not affect the measurement result of the omega gas. Therefore, in the case of simultaneous measurement, it can be known that the measurement results of the two gases do not change, and it can be further deduced that when different kinds of gases are not packaged with sealed containers, as long as no gas mixing occurs, the concentration of the gas will not change.

[0072] Further, as an implementation of the method described above Figure 1 , the embodiment of the present application also provides a gas volume concentration calculation device for implementing the method described above Figure 1 . The device embodiment corresponds to the foregoing method embodiment, and for the sake of reading, the details of the foregoing method embodiment will not be described one by one, but it should be clear that the device in the present embodiment can correspondingly implement all the contents in the foregoing method embodiment. As Figure 3 indicated, the device comprises a first acquisition unit 21 and a second acquisition unit 22, wherein

[0073] The first acquisition unit 21 is configured to acquire first spectrum information and second spectrum information after passing through a first gas cell and a second gas cell in the same detection distance in a target space, wherein the first gas cell and the second gas cell are sealed spaces in the target space, the first gas cell and the second gas cell are pre-charged with the same kind of pre-charged gas or vacuum, and the pre-charged gas is different from the target gas in the target space.

[0074] The second acquisition unit 22 is configured to acquire the gas volume concentration of the target gas based on the first spectrum information and the second spectrum information.

[0078] determine a second gas column concentration of the second region based on the second spectrum information;

[0085] Exemplarily, the lengths of the first gas cell and the second gas cell are different.

[0086] Exemplarily, the distance between the first gas cell and the second gas cell is less than a preset distance.

In the above scheme, two gas cells with different lengths are arranged in the target space, the actual concentration of the gas is estimated based on the two gas cells with different lengths, the pre-charged gas is different from the target gas in the target space, so that the gas absorption peak is different, and the concentration of the pre-charged gas does not affect the measurement result of the target gas, thereby solving the problem that the traditional method cannot measure the actual concentration of the gas.
