Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0037] See also Figure 1 , is a flow chart of a runway cleaning method under extreme weather conditions provided by an embodiment of the present invention, including S1 to S3:

[0038] S1. Acquire meteorological message data and environmental monitoring data; wherein the meteorological message data includes meteorological code, meteorological temperature, meteorological visibility and dew point temperature, and the environmental monitoring data includes environmental temperature and environmental visibility;

[0039] S2. When the meteorological message data and / or the environmental monitoring data meet at least one trigger condition of the thermal radiation system startup conditions, the radiation temperature of the thermal radiation system is set according to the external temperature and the thermal radiation system is started; wherein the external temperature is the minimum value between the meteorological temperature and the environmental temperature, and the thermal radiation system is used to heat the monitored runway;

[0040] S3, when the heat radiation system is in the on state, and the meteorological message data and the environmental monitoring data meet all the heat radiation system shut-down conditions, shut down the heat radiation system;

[0041] The heat radiation system activation condition includes a snowfall trigger condition, a first icing trigger condition and a second icing trigger condition, wherein the snowfall trigger condition is that at least one of the meteorological codes appears in a preset meteorological code set;

[0042] The first icing triggering condition is that the outside temperature is less than a first preset temperature threshold, and the outside visibility is less than a first preset visibility threshold; wherein the outside visibility is the minimum value of the meteorological visibility and the environmental visibility;

[0043] The second icing triggering condition is that the outside temperature is less than a second preset temperature threshold, and the outside temperature is less than or equal to the dew point temperature; wherein the first preset temperature threshold is less than the second preset temperature threshold.

[0044] In step S1, meteorological message data is obtained through the Meteorological Terminal Aviation Routine Weather Report (METAR) and the Terminal Aerodrome Forecasts (TAF). Exemplarily, METAR includes meteorological message data such as temperature (meteorological temperature), dew point temperature, wind direction, wind speed, cloud height, visibility (meteorological visibility), runway visual range, corrected sea level pressure, precipitation, snowfall, freezing rain, freezing fog, fog and thunder. TAF uses a similar code to METAR and is a supplement to its information. Furthermore, TAF is generally updated 4 times a day, at 00:00Z, 06:00Z, 12:00Z and 18:00Z (Z refers to the Universal Time Coordinated), and each TAF is generally valid for 24 hours or 30 hours, within a range of approximately 8 kilometers from the center of the airport runway.

[0045] Further, the monitoring data in step S1 may include ambient temperature, ambient visibility and humidity, and the ambient temperature, ambient visibility and humidity are measured and obtained by a temperature sensor, a visibility sensor and a humidity sensor, respectively, wherein the number of each sensor may be greater than 1, or may be equal to 1, and each sensor may be installed on an airport runway pavement, an apron pavement or a taxiway pavement, or may be installed on an airport runway pavement, an apron pavement and a taxiway pavement at the same time. The number and setting position of each sensor may be modified according to actual needs and are not limited here.

[0046] It is worth noting that the embodiment of the present invention not only obtains temperature / visibility (named as meteorological temperature / meteorological visibility) through weather forecast, but also obtains temperature / visibility (named as ambient temperature / ambient visibility) through sensors installed at the runway site, and then takes the minimum value of the meteorological temperature and the ambient temperature as the outside temperature, and takes the minimum value of the meteorological visibility and the ambient visibility as the outside visibility, so as to judge whether the conditions for starting the thermal radiation system are met based on the outside temperature and / or the outside visibility, so that the runway can be heated more timely before snowfall or runway icing, thereby avoiding snow accumulation and icing on the runway, and having stronger predictability and timeliness.

[0047] Furthermore, in step S2, the conditions for starting the thermal radiation system include multiple trigger conditions, such as a snowfall trigger condition, a first ice formation trigger condition, and a second ice formation trigger condition. The thermal radiation system is turned on as long as one of the trigger conditions is met. In addition, the embodiment of the present invention also sets the radiation temperature of the thermal radiation system according to the external temperature, thereby reducing energy consumption while improving the snow melting and anti-icing efficiency.

[0048] Further, the snowfall trigger condition is that at least one meteorological code appears in a preset meteorological code set, wherein the meteorological code set includes -SN, SN, +SN, RASN and FZRA (representing light snowfall, moderate snowfall, heavy snowfall, sleet and freezing rain, respectively). That is, the snowfall trigger condition is that the meteorological code contains at least one of -SN, SN, +SN, RASN and FZRA.

[0049] Furthermore, it has been found through research that road surface icing is not only related to the atmospheric temperature, but also to whether there is visible moisture (such as whether there is rain, snow, sleet, ice crystals and fog that reduce visibility). Therefore, the first icing trigger condition is that the outside temperature is less than the first preset temperature threshold and the outside visibility is less than the first preset visibility threshold, wherein the first preset temperature threshold can be 5°C and the first preset visibility threshold can be 1500 meters. That is, the first icing trigger condition is that the outside temperature is less than 5°C and the outside visibility is less than 1500 meters.

[0050] Furthermore, in some cases, although the outside temperature is higher than the first preset temperature threshold, the outside temperature may still be lower than the dew point temperature, and ice may still form at this time. Therefore, the embodiment of the present invention further sets a second ice formation trigger condition. Specifically, the second ice formation trigger condition is that the outside temperature is lower than the second preset temperature threshold, and the outside temperature is lower than or equal to the dew point temperature, wherein the second preset temperature threshold is higher than the first preset temperature threshold, and the second preset temperature threshold can be 10°C. That is, the second ice formation trigger condition is that the outside temperature is lower than 10°C, and the outside temperature is lower than or equal to the dew point temperature.

[0051] Compared with the prior art, the embodiment of the present invention can include a variety of meteorological conditions that may cause icing by setting the first icing trigger condition and the second icing trigger condition at the same time, avoiding omissions, thereby accurately predicting whether the runway is about to freeze, and promptly turning on the thermal radiation system to heat the runway before the runway is about to freeze, thereby effectively achieving snow melting and anti-icing.

[0052] Furthermore, in step S3, when all heat radiation system shut-down conditions are met, the heat radiation system is shut down to stop heating the runway.

[0053] It is worth noting that in the prior art, when removing snow and ice, it is generally mechanical snow removal through de-icing vehicles, and chemical de-icing through type I, II and IV de-icing fluids. However, the de-icing efficiency of de-icing vehicles is low, and the de-icing and snow removal effect is not thorough, which may leave a thin layer of ice on the runway pavement, endangering the flight safety of aircraft take-off and landing; and the de-icing and snow removal effect of de-icing fluids is poor in extreme weather such as heavy snowfall and low temperature, and the large-scale use of de-icing fluids will pollute the environment and even damage the airport pavement. Furthermore, mechanical snow removal and chemical de-icing can only work after snow accumulation or ice formation, and cannot be prevented in advance. In order to solve the above-mentioned defects of the prior art, the embodiment of the present invention uses a thermal radiation system for snow melting and ice removal, so that when it is predicted that snowfall or ice is about to fall, the radiation system can be turned on in advance to heat the runway to avoid snow and ice accumulation on the runway. Taking a step back, even if snow or ice has already accumulated on the runway, the thermal radiation system can be used for snow melting and ice removal, so that the accumulated snow and ice can be removed more quickly and thoroughly, thereby improving the efficiency and quality of snow and ice removal without polluting the environment or damaging the runway.

[0054] Compared with the prior art, the embodiments of the present invention obtain meteorological message data and environmental monitoring data, and combine the snowfall trigger condition, the first icing trigger condition and the second icing trigger condition to predict whether snowfall or icing is about to occur in the runway environment. Before snowfall or icing is about to occur, the thermal radiation system can be turned on to heat the runway to prevent snow accumulation and ice formation on the runway, thereby ensuring the normal operation of flights.

[0055] As an optional implementation, the radiation temperature is calculated by the following formula:

[0056]

[0057] Among them, T 辐射 represents the radiation temperature; T 外界 represents the outside temperature; H represents the decision altitude; r represents the vertical decrease rate of atmospheric temperature; T 结冰 Indicates the outside atmospheric freezing temperature.

[0058] For example, H can be 60 (meters); r can be 0.6, because in standard atmosphere, the temperature decreases by 0.6°C for every 100-meter increase in altitude; T 结冰 A conservative value of 10°C can be used. Then, in this embodiment, formula (1) can be expressed as shown in formula (2):

[0059]

[0060] Then, from formula (2), we can get formula (3):

[0061] T radiation ≥ 10.36-T outside world (3)

[0062] Furthermore, according to the principle of rounding up the temperature, we can further obtain formula (4):

[0063] T radiation ≥ 11-T outside world (4)

[0064] As an optional implementation manner, the thermal radiation system activation condition also includes a fogging trigger condition, and the fogging trigger condition is that the meteorological code includes a fogging meteorological code, and the outside visibility is less than a second preset visibility threshold.

[0065] It is worth noting that, in addition to rain, snow and freezing rain, fog is also an extreme weather. In other words, in addition to the snow and ice on the runway that will delay the normal operation of the flight, fog will also reduce visibility, thereby affecting the normal operation of the flight. Therefore, the embodiment of the present invention adopts a thermal radiation system, which can not only achieve snow melting and ice prevention, but also achieve fog dispersion, thereby ensuring that the environment around the runway (mainly visibility) can meet the flight operation requirements even in the case of fog. In order to determine when it is necessary to turn on the thermal radiation system to disperse the fog, the embodiment of the present invention also provides a fog trigger condition. In the fog trigger condition, the fog meteorological code is FG, which means fog; the second preset visibility threshold can have a margin based on the airline's first-class operating standard. For example, when the airline's first-class operating standard is 800 meters, the second preset visibility threshold can be 1000 meters. That is, the fog trigger condition is that the meteorological code contains FG and the outside visibility is less than 1000 meters.

[0066] Compared with the prior art, the embodiment of the present invention can not only prevent snow and ice from accumulating on the runway, but also achieve timely fog dispersal by controlling the thermal radiation system, thereby further ensuring the normal operation of flights.

[0067] As one of the optional implementations, the meteorological message data also includes runway visibility range, and the thermal radiation system activation condition also includes a visibility trigger condition, and the visibility trigger condition is that the external visibility is less than or equal to a third preset visibility threshold or the runway visibility is less than or equal to a first preset runway visibility threshold.

[0068] It is worth noting that in some scenarios, although there is no fogging weather code in the weather code, when the outside visibility or runway visibility is still low, the thermal radiation system should still be turned on for heating to ensure that the airport's visibility and runway visibility can meet the conditions for normal aircraft operation and ensure the normal operation of flights. Therefore, the embodiment of the present invention also sets a visibility trigger condition.

[0069] For example, the third preset visibility threshold may be 800 meters, and the first preset runway visibility threshold may be 550 meters. That is, the visibility trigger condition is that the outside visibility is less than or equal to 800 meters or the runway visibility is less than or equal to 550 meters.

[0070] As one of the optional implementations, the environmental monitoring data also includes humidity, and the heat radiation system startup condition also includes a humidity trigger condition, and the humidity trigger condition is that the difference between the ambient temperature and the dew point temperature is less than a third preset temperature threshold, and the humidity is greater than or equal to a first preset humidity threshold.

[0071] It is worth noting that fogging is likely to occur when the outside temperature is too close to the dew point temperature. Therefore, the embodiment of the present invention also sets a humidity trigger condition to determine whether fogging is about to occur by monitoring the difference between the outside temperature and the dew point temperature and the humidity. Exemplarily, the third preset temperature threshold can be 2°C, and the first preset humidity threshold can be 80%. That is, the humidity trigger condition is that the difference between the outside temperature and the dew point temperature is less than 2°C, and the humidity is greater than or equal to 80%.

[0072] It is worth mentioning that the fog triggering conditions, visibility triggering conditions and humidity triggering conditions can predict whether fog is about to occur from multiple angles, thereby achieving more accurate prediction, which can be used to control the thermal radiation system to disperse fog according to the prediction results, avoiding flight delays due to fogging.

[0073] As an optional implementation manner, the environmental monitoring data further includes humidity, and the meteorological message data further includes runway visual range, then, the thermal radiation system shutdown condition includes:

[0074] Any of the meteorological codes is not a foggy meteorological code and is not in the meteorological code set;

[0075] The outside temperature is greater than or equal to the second preset temperature threshold, and the difference between the outside temperature and the dew point temperature is greater than a target difference;

[0076] The humidity is less than a target humidity threshold;

[0077] The outside visibility is greater than the target visibility threshold; wherein the target visibility threshold is the maximum value of the preset visibility thresholds in the thermal radiation system activation condition;

[0078] The runway visual range is greater than the target runway visual range.

[0079] It is worth noting that the thermal radiation system can only be turned off when all the sub-conditions in the thermal radiation system shutdown conditions are met. From the above content, it can be seen that the thermal radiation system shutdown conditions include meteorological code sub-conditions, temperature sub-conditions, humidity sub-conditions, visibility sub-conditions and runway visual range sub-conditions.

[0080] For the sake of ease of explanation, it is assumed that in an embodiment of the present invention, the conditions for starting the thermal radiation system include a snowfall trigger condition, a first icing trigger condition, a second icing trigger condition, a fog trigger condition, a visibility trigger condition and a humidity trigger condition, and the values ​​of each threshold are as shown in the above example. Then, the meteorological code sub-condition can be understood as that none of FG, -SN, SN, +SN, RASN and FZRA appears in the meteorological code; further, since the second preset temperature threshold is greater than the first preset temperature threshold, in the temperature sub-condition, the condition that the outside temperature should satisfy is greater than or equal to the second preset temperature threshold, that is, 10°C, and the target difference can be the third preset temperature threshold, that is, 2°C; further, the target humidity threshold can be less than the first preset humidity threshold, for example, the target humidity threshold can be 75%; further, the target visibility threshold is the maximum value of the first preset visibility threshold, the second preset visibility threshold and the third preset visibility threshold. In this embodiment, the target visibility threshold is 1500 meters; further, the target runway visibility threshold is the first preset runway visibility threshold, that is, 550 meters.

[0081] That is, in this embodiment, the thermal radiation system shutdown conditions include: 1. None of FG, -SN, SN, +SN, RASN and FZRA appears in the meteorological code; 2. The outside temperature is greater than or equal to 10°C, and the difference between the outside temperature and the dew point temperature is greater than 2°C; 3. The humidity is less than 75%; 4. The outside visibility is greater than 1500 meters; 5. The runway visual range is greater than 550 meters. Among them, 1 to 5 correspond to the meteorological code sub-condition, temperature sub-condition, humidity sub-condition, visibility sub-condition and runway visual range sub-condition respectively.

[0082] Compared with the prior art, the runway clearing method under extreme weather conditions provided in the embodiment of the present invention obtains meteorological message data and environmental monitoring data; wherein the meteorological message data includes meteorological code, meteorological temperature, meteorological visibility and dew point temperature, and the environmental monitoring data includes ambient temperature and ambient visibility; when the meteorological message data and / or the environmental monitoring data meet at least one triggering condition in the thermal radiation system start-up conditions, the radiation temperature of the thermal radiation system is set according to the outside temperature and the thermal radiation system is turned on; wherein the outside temperature is the minimum value between the meteorological temperature and the ambient temperature; when the thermal radiation system is in the on state, and the meteorological message data and the environmental monitoring data meet all the triggering conditions of the thermal radiation system When the thermal radiation system is turned off, the thermal radiation system is turned off; wherein the thermal radiation system start-up conditions include snowfall trigger conditions, first icing trigger conditions and second icing trigger conditions, wherein the snowfall trigger condition is that at least one of the meteorological codes appears in a preset meteorological code set; the first icing trigger condition is that the outside temperature is less than a first preset temperature threshold, and the outside visibility is less than a first preset visibility threshold; wherein the outside visibility is the minimum value of the meteorological visibility and the environmental visibility; the second icing trigger condition is that the outside temperature is less than a second preset temperature threshold, and the outside temperature is less than or equal to the dew point temperature; wherein the first preset temperature threshold is less than the second preset temperature threshold. The embodiment of the present invention can accurately predict whether snowfall or icing is about to occur, and timely turn on the thermal radiation system to heat the runway before snowfall or icing is about to occur, so as to prevent snow and ice accumulation on the runway and avoid snow and ice accumulation affecting the normal operation of the flight.
