[0023] To make the objectives, technical solutions and advantages of the present invention more clear, the following will, in conjunction with the accompanying drawings in the present invention, clearly and completely describe the technical solutions in the present invention. Apparently, 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 in the present invention without making creative efforts fall within the scope of protection of the present invention.

[0024] The method for monitoring the emission flux of atmospheric pollutants provided by the present invention can measure and calculate the unorganized emission flux of atmospheric pollutants (corresponding to target atmospheric pollutants), and solve the problem that the measurement of atmospheric pollutant factors by current SOF monitoring technology is limited.

[0025] Figure 1 It is a schematic flow chart of the method for monitoring the emission flux of atmospheric pollutants provided by the present invention.

[0026] In an exemplary embodiment of the present invention, in combination with Figure 1 it can be seen that the method for monitoring the emission flux of atmospheric pollutants may include step 110 to step 130, and each step will be introduced separately below.

[0027] In step 110, multiple groups of first emission fluxes of the target atmospheric pollutants are obtained upwind, and multiple groups of second exhaust fluxes of the target atmospheric pollutants are obtained downwind.

[0028] In one embodiment, the mobile monitoring platform and the unmanned aerial vehicle (UAV) monitoring platform can perform information transmission based on a communication connection. In one example, a wireless communication module can be installed on the mobile monitoring platform for signal mutual transmission with the UAV monitoring platform.

[0029] In another example, the mobile monitoring platform can be provided with a Fourier transform infrared spectrometer and a solar tracker. When the mobile monitoring platform is moving, the solar tracker can always point to the sun and introduce sunlight into the Fourier transform infrared spectrometer. Among them, the mobile monitoring platform can include vehicles, ships, large load-carrying aircraft, etc. as the platform base.

[0030] In another embodiment, a GPS device can also be carried and fixed on the mobile monitoring platform to record the position information of the mobile monitoring platform and ensure the synchronous movement of the mobile monitoring platform and the UAV monitoring platform.

[0031] In yet another embodiment, for the UAV monitoring platform, an anemometer, an atmospheric pollutant monitoring sensor, a CPU, a communication module, a GPS, etc. can be provided. Among them, the communication module is used to realize the communication connection between the UAV monitoring platform and the mobile monitoring platform. The GPS is used to record the position information of the UAV monitoring platform for synchronous movement and can also ensure the synchronous movement of the mobile monitoring platform and the UAV monitoring platform.

[0032] The CPU is used to store and analyze the data recorded by the anemometer, the air pollutant monitoring sensor, and the GPS, and automatically control the movement of the UAV monitoring platform in the horizontal and vertical directions after it takes off. In addition, the data stored by the CPU can be transmitted to the mobile monitoring platform through the communication module, which is used to calculate the target air pollutant emission flux according to the real-time recorded data. In other words, the first emission flux and the second emission flux can be obtained based on the monitoring of the emission flux monitoring system.

[0033] In another embodiment, the anemometer and the air pollutant monitoring sensor can be integrated into a module A, and 3 to 10 module As can be suspended at the bottom of the UAV monitoring platform through strong steel wires, with an average distance of 3 to 10 meters between each module. Among them, the air pollutant sensor can simultaneously monitor gas factors such as propane pollutants monitored by the infrared spectrometer, and target air pollutants, such as any one of methane pollutants, benzene series, oxygen-containing volatile organic compounds, nitrogen-containing volatile organic compounds, sulfur-containing volatile organic compounds, and hydrogen sulfide.

[0034] In the present invention, for the sake of convenience of description, the target air pollutant will be taken as an example of methane pollutant for illustration.

[0035] In another embodiment, multiple first emission fluxes of the target air pollutants at the upwind direction obtained based on the emission flux monitoring system can be counted, and multiple second exhaust fluxes of the target air pollutants obtained at the downwind direction can be counted. It should be noted that the methods for obtaining the first emission flux and the second emission flux are the same, except for the acquisition locations.

[0036] Among them, the multiple first emission fluxes of the target air pollutants can be the first emission fluxes of the target air pollutants in different pollution zones. The multiple second emission fluxes of the target air pollutants can be the second emission fluxes of the target air pollutants in different pollution zones.

[0037] In step 120, based on multiple second emission fluxes, the sum of the second emission fluxes is obtained, and based on multiple first emission fluxes, the sum of the first emission fluxes is obtained.

[0038] In step 130, the difference between the sum of the second emission fluxes and the sum of the first emission fluxes is calculated to obtain the emission flux of the target air pollutant.

[0039] In one embodiment, the sum of the second emission fluxes can be obtained based on multiple second emission fluxes at the downwind direction; and then the sum of the first emission fluxes can be obtained based on multiple first emission fluxes at the upwind direction. Further, the difference formed between the sum of the second emission fluxes and the sum of the first emission fluxes is used as the emission flux of the target air pollutant. This embodiment solves the problem that the infrared occultation flux remote sensing monitoring technology is only limited to monitoring air pollutant factors such as non-methane hydrocarbons, some olefins and other volatile organic compounds and a small amount of inorganic components such as ammonia (in this invention, propane pollutant is taken as an example), and can simultaneously monitor the emission fluxes of common air pollutant gases in industrial sites such as methane pollutants, volatile organic compounds such as benzene series, and inorganic air pollutants such as hydrogen sulfide (corresponding to the target air pollutants).

[0040] The method for monitoring the emission flux of air pollutants provided by the present invention is applied to an emission flux monitoring system. The emission flux monitoring system includes a mobile monitoring platform and a drone monitoring platform. The method includes: obtaining multiple first emission fluxes of the target air pollutants at the upwind direction, and obtaining multiple second exhaust fluxes of the target air pollutants at the downwind direction, where the target air pollutants include any one of methane pollutants, benzene series, oxygen-containing volatile organic compounds, nitrogen-containing volatile organic compounds, sulfur-containing volatile organic compounds, and hydrogen sulfide, and the first emission fluxes and the second emission fluxes are obtained based on the monitoring of the emission flux monitoring system; obtaining the sum of the second emission fluxes based on the multiple second emission fluxes, and obtaining the sum of the first emission fluxes based on the multiple first emission fluxes; and then performing a difference operation on the sum of the second emission fluxes and the sum of the first emission fluxes, so as to obtain the emission flux of the target air pollutant. This solves the problem that the current monitoring technology is limited in measuring air pollutant factors.

[0041] Figure 2 It is a schematic flow diagram of obtaining the first emission flux provided by the present invention.

[0042] Next, it will be combined with Figure 2 to illustrate the process of obtaining the first emission flux.

[0043] In an exemplary embodiment of the present invention, combined with Figure 2 it can be known that obtaining the first emission flux may include steps 210 to 240, and each step will be introduced separately below.

[0044] In step 210, when the upwind emission source emits air pollutants, the drone monitoring platform is started to rise to the first height where the air pollutants form a plume, and the mobile monitoring platform is started to move synchronously with the drone monitoring platform at the emission source site of the upwind emission source.

[0045] In one embodiment, when an upwind emission source emits air pollutants, the unmanned aerial vehicle (UAV) monitoring platform can be activated to rise to the first height at which the air pollutants form a plume. In one example, a plurality of module A in the UAV monitoring platform can be deployed and vertically distributed in mid-air, and the height of the UAV monitoring platform can be located based on the approximate height of the upwind emission source known in advance, so that the first height at which the air pollutants form a plume is approximately equivalent to the height at which the sensors in the UAV monitoring platform are distributed in the air.

[0046] In another embodiment, the mobile monitoring platform can also be activated to move synchronously with the UAV monitoring platform at the emission source site of the upwind emission source. In one example, the mobile monitoring platform can be operated to travel around the air pollutant emission source to be measured or the emission site of the air pollutant emission source. Among them, the GPS modules respectively set in the mobile monitoring platform and the UAV monitoring platform can be used to ensure that the mobile monitoring platform moves synchronously with the UAV monitoring platform at the emission source site of the upwind emission source.

[0047] In step 220, when the mobile monitoring platform monitors the first propane column concentration of propane pollutants, control is performed to synchronously monitor the first pollutant concentration of air pollutants based on a plurality of sensors provided on the UAV monitoring platform, and to synchronously monitor the first wind speed based on a plurality of anemometers matched with the sensors provided on the UAV monitoring platform.

[0048] Among them, the air pollutants at least include propane pollutants and target air pollutants. The monitoring of the first propane column concentration of propane pollutants by the mobile monitoring platform can be realized by a Fourier transform infrared spectrometer provided on the mobile detection platform.

[0049] In one embodiment, when the mobile monitoring platform monitors the first propane column concentration of propane pollutants, control is performed to synchronously monitor the first pollutant concentration of air pollutants based on a plurality of sensors provided on the UAV monitoring platform, and to synchronously monitor the first wind speed based on a plurality of anemometers matched with the sensors provided on the UAV monitoring platform.

[0050] In another example, when the mobile monitoring platform monitors the first propane column concentration of propane pollutants, the UAV monitoring platform can adjust its flight height to ensure that the concentration of propane monitored by the sensor at the middle position is higher than the concentrations of the sensors at both ends.

[0051] During the application process, the UAV monitoring platform can send the propane pollutant concentration, target atmospheric pollutant concentration, first wind speed monitored by the anemometer, and wind direction data monitored by each sensor to the computer data analysis system of the mobile monitoring platform. This system can calculate the emission flux of the monitored target atmospheric pollutants (which can correspond to the first emission flux) based on the integrated propane column concentration data monitored by the infrared spectrometer (corresponding to the first propane column concentration), the propane pollutant concentration, target atmospheric pollutant concentration, first wind speed monitored by the anemometer, and GPS position data (corresponding to the first position information).

[0052] It should be noted that the first propane column concentration of the propane pollutants monitored by the mobile monitoring platform can also be achieved by the column concentrations of other VOCs factors. In this embodiment, the propane column concentration is taken as an example for illustration.

[0053] In step 230, obtain the first position information of the emission flux monitoring system corresponding to the case where the first pollutant concentration is obtained.

[0054] In step 240, based on the first propane column concentration, first wind speed, first pollutant concentration, and first position information, obtain the first emission flux.

[0055] In one embodiment, it is also possible to obtain the first position information of the emission flux monitoring system corresponding to the case where the first pollutant concentration is obtained, and based on the first propane column concentration, first wind speed, first pollutant concentration, and first position information, obtain the first emission flux.

[0056] It should be noted that the calculation of the first emission flux of the target atmospheric pollutants is divided into the following two cases, which will be described separately below.

[0057] In an exemplary embodiment of the present invention, the first pollutant concentration may include the first propane pollutant concentration and the first target atmospheric pollutant concentration. Continuing with the example described above Figure 2 as an example for illustration, obtaining the first emission flux (corresponding to step 240) based on the first propane column concentration, first wind speed, first pollutant concentration, and first position information can be achieved in the following manner:

[0058] In the case where multiple sensors provided on a drone monitoring platform include a first sensor and a second sensor, based on the first propane pollutant concentration, the first comprehensive propane pollutant concentration, the first propane column concentration, and the first target atmospheric pollutant concentration monitored by the first sensor, the column concentration of the first target atmospheric pollutant is obtained, where the first sensor is a sensor that simultaneously monitors the first propane pollutant concentration and the first target atmospheric pollutant concentration; the second sensor is a sensor that only monitors the first propane pollutant concentration; the first comprehensive propane pollutant concentration includes the first propane pollutant concentration monitored by the first sensor and the first propane pollutant concentration monitored by the second sensor;

[0059] Based on the column concentration of the first target atmospheric pollutant, the first wind speed, and the first position information, the first emission flux is obtained.

[0060] In one embodiment, in the case where multiple sensors on the drone monitoring platform include a first sensor that can simultaneously monitor the first propane pollutant concentration and the first target atmospheric pollutant concentration, and a second sensor that only monitors the first propane pollutant concentration, the first emission flux can be achieved using formula (1):

[0061]

[0062] where Flux represents the first emission flux; y represents the position information recorded by GPS when collecting spectral data once (corresponding to the first propane column concentration), that is, the first position information; c 柱a (y) represents the column concentration of the target atmospheric pollutant at the y position, that is, the column concentration of the first target atmospheric pollutant; c 柱 (y) represents the column concentration data of propane monitored by the spectrometer at the y position, that is, the first propane column concentration; y1 and y2 represent the position information of the mobile monitoring platform from the start to the end of propane monitoring, that is, the starting position and the ending position of the propane pollution zone profile; c ai (y) represents the response value of the i-th sensor on the drone monitoring platform that has a response value to the target atmospheric pollutant at the y position to the target atmospheric pollutant, that is, the first target atmospheric pollutant concentration monitored by the first sensor; c si (y) represents the response value of the i-th sensor on the drone monitoring platform that has a response value to propane at the y position to propane, that is, the first comprehensive propane pollutant concentration; c sai (y) represents the response value of the i-th sensor on the drone monitoring platform that has a response value to both the target atmospheric pollutant and propane at the y position to propane, that is, the first propane pollutant concentration monitored by the first sensor. Where n represents the number of sensors. It should be noted that the sensors and the anemometers are in one-to-one correspondence. Therefore, n can also represent the number of anemometers; v⊥ The wind speed component value perpendicular to the moving direction of the mobile monitoring platform monitored by the anemometer at the same position as the i-th sensor that responds to both the target air pollutant and propane at the y position monitored by the UAV monitoring platform is represented by i(y), that is, the wind speed component value of the first wind speed perpendicular to the moving direction of the mobile monitoring platform.

[0063] In another exemplary embodiment of the present invention, the first pollutant concentration may include the first propane pollutant concentration and the first target air pollutant concentration. Continuing with the example described above Figure 2 as an example, based on the first propane column concentration, the first wind speed, the first pollutant concentration, and the first position information, obtaining the first emission flux (corresponding to step 240) can be achieved in the following manner:

[0064] In the case where the multiple sensors disposed on the UAV monitoring platform include a first sensor, a second sensor, and a third sensor, based on the first propane column concentration, the first wind speed, the first pollutant concentration, and the first position information, a first sub-emission flux is obtained, and

[0065] based on the first wind speed, the first pollutant concentration, and the first position information, a second sub-emission flux is obtained, where the first sensor is a sensor that simultaneously monitors the first propane pollutant concentration and the first target air pollutant concentration; the second sensor is a sensor that only monitors the first propane pollutant concentration; the third sensor is a sensor that only monitors the first target air pollutant concentration;

[0066] Based on the sum of the first sub-emission flux and the second sub-emission flux, the first emission flux is obtained.

[0067] In one embodiment, in the case where the multiple sensors on the UAV monitoring platform include a first sensor that can simultaneously monitor the first propane pollutant concentration and the first target air pollutant concentration, a second sensor that only monitors the first propane pollutant concentration, and a third sensor that only monitors the first target air pollutant concentration, the first emission flux can be calculated in two parts, that is, based on the first propane column concentration, the first wind speed, the first pollutant concentration, and the first position information, a first sub-emission flux is obtained; and based on the first wind speed, the first pollutant concentration, and the first position information, a second sub-emission flux is obtained, and then the first sub-emission flux and the second sub-emission flux are summed to obtain the final first emission flux.

[0068] The processes of determining the first sub-emission flux and the second sub-emission flux will be introduced separately below.

[0069] In an exemplary embodiment of the present invention, based on the first propane column concentration, the first wind speed, the first pollutant concentration, and the first position information, the first sub-emission flux can be obtained in the following manner:

[0070] Based on the first propane pollutant concentration, the first propane column concentration, the first comprehensive propane pollutant concentration monitored by the first sensor, and the first target atmospheric pollutant concentration monitored by the first sensor, the first component column concentration of the first target atmospheric pollutant within the spatial range between multiple first sensors is obtained, where the first comprehensive propane pollutant concentration includes the first propane pollutant concentration monitored by the first sensor and the first propane pollutant concentration monitored by the second sensor;

[0071] Based on the first component column concentration of the first target atmospheric pollutant, the first wind speed, and the first position information, the first sub-emission flux is obtained.

[0072] The process of obtaining the first sub-emission flux will be described below with reference to formula (2):

[0073]

[0074] Among them, in addition to referring to the description of formula (1) for the meaning of each parameter in formula (2), c 柱a1 (y) represents the column concentration of the target atmospheric pollutant within the spatial range between sensors that respond to both the target atmospheric pollutant and propane at position y; that is, the first component column concentration of the first target atmospheric pollutant within the spatial range between multiple first sensors.

[0075] In another exemplary embodiment of the present invention, based on the first wind speed, the first pollutant concentration, and the first position information, the second sub-emission flux can be obtained in the following manner:

[0076] Based on the first target atmospheric pollutant concentration monitored by the first sensor, the first target atmospheric pollutant concentration monitored by the target sensor, and the first component column concentration of the first target atmospheric pollutant, the second component column concentration of the first target atmospheric pollutant is obtained, where the target sensor is a sensor in a target sensor array composed of a third sensor and a first sensor adjacent to the third sensor;

[0077] Based on the second component column concentration of the first target atmospheric pollutant, the first wind speed, and the first position information, the second sub-emission flux is obtained.

[0078] In one embodiment, the second sub-emission flux can be represented by formula (3):

[0079]

[0080] Among them, In addition to referring to the description of formula (1), the meanings of the parameters in formula (3) are as follows. For c ali (y) represents the response value of the i-th sensor in the sensors that only respond to the target atmospheric pollutant and an adjacent sensor that responds to both at the y position monitored by the UAV monitoring platform to the target atmospheric pollutant, that is, the concentration of the first target atmospheric pollutant monitored by the target sensor; v ⊥li (y) represents the wind speed component value perpendicular to the moving direction of the moving monitoring platform monitored by the anemometer at the same position as the i-th sensor in the sensors that only respond to the target atmospheric pollutant factor and an adjacent sensor that responds to both at the y position monitored by the UAV monitoring platform, that is, the corresponding first wind speed component value. Among them, the target sensor is the sensor in the target sensor array composed of the third sensor and a first sensor adjacent to the third sensor.

[0082] Through the foregoing embodiments, especially based on formulas (1)-(3), the emission flux of the target atmospheric pollutant can be accurately determined in different cases, thus solving the problem that the current monitoring technology is limited in measuring atmospheric pollutant factors.

[0083] It should be noted that the method for obtaining the second emission flux is the same as that for the first emission flux, except that one is upwind and the other is downwind. The specific determination process can refer to the determination process of the first emission flux.

[0084] In an exemplary embodiment of the present invention, the second emission flux can be obtained in the following manner:

[0085] In the case where the downwind emission source emits atmospheric pollutants, start the UAV monitoring platform to rise to the second height where the atmospheric pollutants form a plume, and start the moving monitoring platform to move synchronously with the UAV monitoring platform at the emission source site of the downwind emission source;

[0086] When the moving monitoring platform monitors the second propane column concentration of propane pollutants, control the multiple sensors set on the UAV monitoring platform to synchronously monitor the second pollutant concentration of the atmospheric pollutants, and synchronously monitor the second wind speed based on multiple anemometers matched with the sensors on the UAV monitoring platform. Among them, the atmospheric pollutants at least include propane pollutants and the target atmospheric pollutant, and

[0087] Obtain the second position information of the emission flux monitoring system corresponding to the case of obtaining the second pollutant concentration;

[0088] Based on the second propane column concentration, the second wind speed, the second pollutant concentration, and the second location information, the second emission flux is obtained.
