Description

Technical Field

[0001] This invention belongs to the field of air pollution control technology, and relates to a drone performance / environmental protection system and method that can adsorb and purify pollutants. Background Technology

[0002] Fireworks produce large amounts of particulate matter (PM2.5, PM10), sulfur dioxide, nitrogen oxides (NOx), and heavy metal pollutants, seriously affecting air quality and human health. In recent years, most parts of my country have strictly banned the setting off of fireworks and firecrackers. Some areas have alleviated pollution problems by designating designated areas for centralized fireworks displays or by imposing bans. However, centralized fireworks displays can still lead to local pollution exceeding standards.

[0003] Furthermore, with the rise and development of the low-altitude economy, drone performances and fireworks displays have become important forms of celebration during holidays. Although fireworks displays are concentrated in a single event, pollution control is still necessary. However, traditional ground-based purification equipment is inadequate to handle such dynamic pollution sources and cannot respond quickly enough. Moreover, fireworks displays are prone to causing fires, and traditional firefighting methods suffer from response delays. Summary of the Invention

[0004] The technical problem solved by this invention is to provide a drone performance / environmental protection system and method that can adsorb and purify pollutants, which can reduce environmental pollution and safety risks while meeting the performance effects of drone / fireworks shows.

[0005] This invention is achieved through the following technical solution:

[0006] A drone performance / environmental protection system capable of adsorbing and purifying pollutants includes a drone performance formation controlled by a central control station, and a gas purification device mounted on the drones of the performance formation. The gas purification device has built-in adsorbent and multiple through holes on its surface.

[0007] During fireworks displays and drone shows, the central control unit dynamically controls the drone formation and sends commands to the drone formation to move its position and change its shape; drones equipped with gas purification devices absorb and eliminate pollutants generated after the fireworks are set off while performing drone shows.

[0008] In addition, air quality monitoring equipment sends warning information and coordinate information to the central control station when it detects that the concentration of pollutants in the area has reached the threshold.

[0009] Firefighting drones receive instructions from a central control station to spray or extinguish fires in designated areas; alternatively, they can be controlled by a pilot to fly to designated areas to spray or extinguish fires.

[0010] Furthermore, the central control unit is equipped with a drone formation module, an air quality monitoring module, and a fire alarm module;

[0011] The drone formation module communicates bidirectionally with the drone performance formation through the central control console, receives the drone performance formation's positioning information and obstacle avoidance information from the cluster system, and issues commands to control the drone performance formation to move and change the light color.

[0012] The air quality monitoring module receives image information, gas concentration monitoring information, wind speed and wind direction information uploaded by the air quality monitoring equipment.

[0013] The fire alarm module receives the location of the fire source and image transmission information from the fire detector, flame recognition camera or infrared thermal imaging camera installed on the fire-fighting drone, and generates a fire alarm signal.

[0014] Specifically, the gas purification device is provided with a hollow receiving cavity, in which an adsorbent that can absorb pollutants from fireworks is placed.

[0015] Each surface of the gas purification device is provided with through holes that communicate with the receiving cavity, and the pore size of the through holes is smaller than the particle size of the adsorbate;

[0016] The adsorbent material inside the containment cavity can move / tumble with the movement of the drone.

[0017] Specifically, the gas purification device includes two hemispheres connected by snap-fit, each hemisphere having a through hole; the adsorbent is one or more of activated carbon, molecular sieve, and sponge.

[0018] Specifically, the gas purification device is a gypsum-made shape or component with an internal cavity and multiple through holes on its surface that communicate with the cavity.

[0019] Alternatively, the gas purification device may be made of transparent plastic molded with adsorbent and reflective strips or reflective microspheres inside;

[0020] The gas purification device is also decorated with ornaments or lights for troop formation performances.

[0021] Furthermore, the gas purification device is also equipped with a miniature air pump, which is powered by the drone's battery.

[0022] The power supply switch of the miniature air pump is turned on and off according to the command of the central control panel; the power supply switch is normally off, and when necessary, the power supply switch is switched to the on state according to the command, and the miniature air pump starts to pump air.

[0023] The air intake port of the miniature air pump is connected to a through hole of the adsorption device. Air enters the air intake port from the adsorbent in the adsorption device and is then discharged through the exhaust port of the miniature air pump.

[0024] Furthermore, the drones in the drone performance formation are equipped with positioning modules and obstacle avoidance systems, receive instructions from the central control station to fly in dynamic formation, and change performance shapes according to the instructions.

[0025] During fireworks and drone shows, air quality monitoring equipment monitors the air quality in the fireworks display area in real time and uploads the monitoring information to the central control station; the central control station then displays the information, including the distribution and concentration of pollutants, in a visual manner.

[0026] The air quality monitoring equipment is also equipped with a wind vane and an anemometer to monitor the direction and speed of the spread of pollutants from fireworks displays;

[0027] Based on the visualized information, the operator selects the preset performance formation program through the central control panel, and manipulates the drone performance formation to fly to areas with high pollution concentrations to absorb and eliminate pollutants, while simultaneously forming performance formations.

[0028] The air quality monitoring equipment and the central control console are connected via CAN communication or RS485 communication.

[0029] The air quality monitoring equipment uses infrared light to monitor particulate matter, sulfur dioxide, nitrogen oxides (NOx), and heavy metal pollutants in the air after fireworks are set off in real time from a distance; the sampling frequency is 5-20 times / s.

[0030] This invention also provides a method for drone performances / eco-friendly fireworks shows that can adsorb and purify pollutants, comprising the following operations:

[0031] 1) A gas purification device is installed on the drones of the performance formation. The gas purification device has a built-in adsorbent and multiple through holes on its surface.

[0032] 2) The central control console includes a drone performance formation program;

[0033] 3) When performing fireworks and drone shows, the central control station dynamically controls the drone performance formation and sends instructions to the drone performance formation to move its position and change its shape according to the preset program;

[0034] Drones equipped with gas purification devices can absorb and eliminate pollutants generated after fireworks are set off while performing drone shows.

[0035] 4) It is also equipped with air quality monitoring equipment. When the concentration of pollutants in the area reaches the first-level threshold, it sends warning information and coordinate information to the central control station.

[0036] The operator selects a preset performance formation program through the central control console. The central control console sends instructions to the drone performance formation, which then flies to areas with high pollution concentrations to absorb and eliminate pollutants while simultaneously forming performance formations.

[0037] During adsorption and elimination, the drone performance formation can move its position or change its performance shape;

[0038] 5) When the concentration of pollutants in the area is detected to reach the secondary threshold, the central control station also sends instructions to the fire-fighting drone to spray the designated area; or the pilot controls the fire-fighting drone to fly to the designated area to spray.

[0039] Furthermore, it is also equipped with fire-fighting drones, which can quickly locate the fire source by installing fire detectors, flame recognition cameras or infrared thermal imaging cameras, and upload the image information to the central control station to send an alarm signal.

[0040] When unburned fireworks cause a fire, the fire-fighting drone receives instructions from the central control station to spray or extinguish the fire in the designated area.

[0041] Alternatively, operators can fly firefighting drones over the fire source and use liquid or dry powder fire extinguishing bombs carried by the drones to extinguish the fire initially and control its spread.

[0042] After receiving the alarm signal from the central control station, firefighters quickly arrived at the fire scene to carry out firefighting and rescue operations.

[0043] Compared with the prior art, the present invention has the following beneficial technical effects:

[0044] The present invention provides a drone performance / environmental protection system and method that can adsorb and purify pollutants, which can take into account both the performance of drones / fireworks shows and the prevention and control of environmental pollution. By equipping the drones in the drone performance formation with gas purification devices, when the fireworks show and the drone performance take off at the same time (or the drones take off before the fireworks), when the fireworks release pollutants, the drone formation can fly to the place where the concentration of pollutants from the fireworks is relatively high to adsorb and eliminate them.

[0045] Considering both performance and aesthetics, the drone performance formation is controlled by a central control station. During movement or adsorption / elimination, the drone formation forms shapes (including changes in position or shape). In other words, the drone formation combines adsorption / elimination with performance elements, achieving real-time adsorption of air pollutants generated by fireworks in a very economical way. This can reduce environmental pollution from drone performances / fireworks shows without increasing costs, and alleviate some of the limitations of drone performances / fireworks shows. Furthermore, the adsorbent in the gas purification device carried by the drone can be replaced periodically, and the adsorbent that has absorbed pollutants is centrally treated to render it harmless.

[0046] This invention can absorb and eliminate pollution generated by fireworks in real time during fireworks displays, thus avoiding air pollution; the air monitoring equipment can monitor and detect air pollution in real time, and the drone control console can direct drone formations to move to heavily polluted areas for absorption and elimination; the fire-fighting drones can also quickly extinguish fires in the event of a fire, achieving the goal of integrated detection, prevention and firefighting, taking into account environmental protection, safety and entertainment.

[0053] The present invention will be further described in detail below with reference to embodiments. These descriptions are for illustrative purposes only and are not intended to limit the scope of the invention.

[0054] Given that existing technologies lack a systematic solution that combines drone performance formations to dynamically absorb pollutants from fireworks displays with real-time air quality monitoring and fire safety coordination, this invention provides a drone performance / environmental protection system and method capable of absorbing and purifying pollutants, balancing environmental friendliness, safety, and entertainment value.

[0055] See Figures 1-4 A drone performance / environmental protection system capable of adsorbing and purifying pollutants includes a drone performance formation controlled by a central control station, and a gas purification device mounted on the drones of the performance formation. The gas purification device has built-in adsorbent and multiple through holes on its surface.

[0056] During fireworks displays and drone shows, the central control unit dynamically controls the drone formation and sends commands to the drone formation to move its position and change its shape; drones equipped with gas purification devices absorb and eliminate pollutants generated after the fireworks are set off while performing drone shows.

[0057] In addition, air quality monitoring equipment sends warning information and coordinate information to the central control station when it detects that the concentration of pollutants in the area has reached the threshold.

[0058] Firefighting drones receive instructions from a central control station to spray or extinguish fires in designated areas; alternatively, they can be controlled by a pilot to fly to designated areas to spray or extinguish fires.

[0059] A method for drone performances / eco-friendly fireworks shows that can absorb and purify pollutants includes the following operations:

[0060] 1) A gas purification device is installed on the drones of the performance formation. The gas purification device has a built-in adsorbent and multiple through holes on its surface.

[0061] 2) The central control console includes a drone performance formation program;

[0062] 3) When performing fireworks and drone shows, the central control station dynamically controls the drone performance formation and sends instructions to the drone performance formation to move its position and change its shape according to the preset program;

[0063] Drones equipped with gas purification devices can absorb and eliminate pollutants generated after fireworks are set off while performing drone shows.

[0064] 4) It is also equipped with air quality monitoring equipment. When the concentration of pollutants in the area reaches the first-level threshold, it sends warning information and coordinate information to the central control station.

[0065] The operator selects a preset performance formation program through the central control console. The central control console sends instructions to the drone performance formation, which then flies to areas with high pollution concentrations to absorb and eliminate pollutants while simultaneously forming performance formations.

[0066] During adsorption and elimination, the drone performance formation can move its position or change its performance shape;

[0067] 5) When the concentration of pollutants in the area is detected to reach the secondary threshold, the central control station also sends instructions to the fire-fighting drone to spray the designated area; or the pilot controls the fire-fighting drone to fly to the designated area to spray.

[0068] Furthermore, it is also equipped with fire-fighting drones, which can quickly locate the fire source by installing fire detectors, flame recognition cameras or infrared thermal imaging cameras, and upload the image information to the central control station to send an alarm signal.

[0069] When unburned fireworks cause a fire, the fire-fighting drone receives instructions from the central control station to spray or extinguish the fire in the designated area.

[0070] Alternatively, operators can fly firefighting drones over the fire source and use liquid or dry powder fire extinguishing bombs carried by the drones to extinguish the fire initially and control its spread.

[0071] After receiving the alarm signal from the central control station, firefighters quickly arrived at the fire scene to carry out firefighting and rescue operations.

[0072] In the above scheme, once the fireworks show begins, the shape and position of the drones in the air can be changed. Each drone in the drone performance team is equipped with a gas purification device that can actively absorb pollutants in the air. Pollutants are generated at the same time as the fireworks show, and the drones begin to absorb and eliminate them at this time, instead of waiting until the fireworks show ends before taking off to absorb and eliminate them. This allows the fireworks show and drone performance to be carried out simultaneously, taking into account environmental protection, safety and entertainment value.

[0073] The drone performance team's movements are primarily determined by air quality monitoring equipment detecting areas with high pollution concentrations. When the pollutant concentration in an area reaches the first-level threshold, the central control station sends commands to the drones, instructing the drone performance team to fly towards that area and simultaneously form formations. The central control station has pre-set N drone formations; based on on-site monitoring information, the team selects one formation from these N formations to move, or alternates between several formations, resulting in a performance that is both aesthetically pleasing and environmentally friendly.

[0074] The following is a detailed explanation of each part.

[0075] See Figure 2 , Figure 3 , Figure 4 The central control unit is equipped with a drone formation module, an air quality monitoring module, and a fire alarm module;

[0076] The drone formation module communicates bidirectionally with the drone performance formation through the central control console, receives the drone performance formation's positioning information and obstacle avoidance information from the cluster system, and issues commands to control the drone performance formation to move and change the light color.

[0077] The air quality monitoring module receives image information, gas concentration monitoring information, wind speed and wind direction information uploaded by the air quality monitoring equipment.

[0078] The fire alarm module receives the location of the fire source and image transmission information from the fire detector, flame recognition camera or infrared thermal imaging camera installed on the fire-fighting drone, and generates a fire alarm signal.

[0079] The drones in the drone performance formation are equipped with positioning modules and obstacle avoidance systems. They receive instructions from the central control station to fly in dynamic formation and change performance shapes according to the instructions.

[0080] During fireworks and drone shows, air quality monitoring equipment monitors the air quality in the fireworks display area in real time and uploads the monitoring information to the central control station; the central control station then displays the information, including the distribution and concentration of pollutants, in a visual manner.

[0081] The air quality monitoring equipment is also equipped with a wind vane and an anemometer to monitor the direction and speed of the spread of pollutants from fireworks displays;

[0082] Based on the visualized information, the operator selects the preset performance formation program through the central control panel, and manipulates the drone performance formation to fly to areas with high pollution concentrations to absorb and eliminate pollutants, while simultaneously forming performance formations.

[0083] Specifically, the communication interface between the air quality monitoring equipment and the central control console uses CAN communication or RS485 communication for connection;

[0084] The air quality monitoring equipment uses infrared technology to monitor particulate matter, sulfur dioxide, nitrogen oxides (NOx), and heavy metal pollutants in the air after fireworks displays in real time over a long distance; the sampling frequency is 5-20 times / s.

[0085] The following are examples of several gas purification devices.

[0086] Example 1

[0087] The gas purification device is equipped with a hollow cavity in which an adsorbent is placed to absorb pollutants from fireworks, thereby adsorbing and eliminating them.

[0088] Each surface of the gas purification device is provided with through holes that communicate with the receiving cavity, and the pore size of the through holes is smaller than the particle size of the adsorbate;

[0089] The adsorbent inside the containment cavity can move / tumble with the movement of the drone; the movement / tumbling of the adsorbent can also enhance the adsorption of pollutants from fireworks.

[0090] Example 2

[0091] The gas purification device includes two hemispheres (preferably plastic balls, which are lightweight and inexpensive) connected by snap-fit, each hemisphere having a through hole; the adsorbent is one or more of activated carbon, molecular sieves, and sponges; the ratio and amount of several adsorbents can be adjusted according to actual conditions.

[0092] Example 3

[0093] The gas purification device is a plaster mold or molded component with an internal cavity; the plaster surface has multiple through holes. The plaster mold is easy to shape and also provides a certain degree of adsorption.

[0094] The gas purification device does not affect the layout of the design. The gas purification device is made of transparent plastic. It can even enrich the design. For example, the gas purification device is equipped with reflective strips or reflective microspheres inside, which are mixed with the adsorbent. The gas purification device can also be decorated with ornaments or lights for troupe performances. This does not affect the adsorption of pollutants and can also create a better design effect.

[0095] Example 4

[0096] like Figure 5 As shown, the gas purification device is also equipped with a miniature air pump (active pump suction type), which is powered by the drone's battery.

[0097] The power supply switch of the miniature air pump is turned on and off according to the command of the central control panel; the power supply switch is normally off, and when necessary, the power supply switch is switched to the on state according to the command, and the miniature air pump starts to pump air.

[0098] The air intake port of the micro air pump is connected to a through hole of the adsorption device. Air enters the air intake port from the adsorbate of the adsorption device and is then discharged through the exhaust port of the micro air pump, thereby enhancing the adsorption efficiency.

[0099] The miniature air pump is turned off during drone performances and turned on when adsorption and removal are needed, achieving the goal of low power consumption.

[0100] The following is an implementation example of the entire system.

[0101] Example 5

[0102] See Figure 1 A drone performance / environmental protection system capable of absorbing and purifying pollutants includes a central control console, a drone performance formation, air quality monitoring equipment (long-distance monitoring), and fire-fighting drones.

[0103] Figure 2 This is a schematic diagram of the central control station dynamically controlling the drone performance formation according to the present invention. When fireworks and drone performances are being performed, the central control station 1 can dynamically control the drone performance formation 2, and send instructions to the drone performance formation 2 at any time to move its position and change its shape. The central control station 1 can also direct the drone performance formation 2 to absorb and eliminate pollutants generated after the fireworks are set off while performing the drone show, thereby improving air quality.

[0104] Among them, the drone performance formation 2 is equipped with a gas purification device. The gas purification device is preferably an active absorption type, which can actively absorb and eliminate pollutants from fireworks in the air. The adsorbent in the gas purification device can be activated carbon, molecular sieve, etc., with adsorbents with a pollution adsorption efficiency of ≥85% being preferred.

[0105] The connection between the drone and the gas purification device is a detachable design, with either a snap-on or screw-on type for easy replacement; the adsorbents, including activated carbon and molecular sieves, can be replaced periodically, and the removed adsorbents can be centrally disposed of in a harmless manner.

[0106] The drone performance formation 2 is equipped with a positioning module and an obstacle avoidance system, supporting dynamic formation flight and allowing for on-the-spot changes in performance formations according to instructions. The positioning module preferably uses a GNSS module with RTK technology, and the obstacle avoidance system preferably employs intra-cluster communication obstacle avoidance technology.

[0107] Figure 3 This is a schematic diagram of the long-distance air quality monitoring system described in this invention. During fireworks and drone performances, the long-distance air quality monitoring device 3 monitors the air quality in the fireworks display area in real time and uploads the monitoring information to the central control station 1. The central control station 1 visualizes the distribution and concentration of pollutants through images. The communication interface between the long-distance air quality monitoring device 3 and the central control station preferably uses CAN communication.

[0108] Air quality monitoring equipment 3 is also equipped with a wind vane and anemometer, which can predict the spread of pollutants from fireworks displays. Based on the visualized information, operators can control the drone performance formation 2 to fly to areas with high pollution concentrations to absorb and eliminate them, while simultaneously forming performance shapes.

[0109] The performance formation consists of N pre-determined formations, one of which is selected based on on-site air quality image feedback. For example, if pollutants are detected concentrated in a certain area, a pre-determined soccer ball formation can be selected; if pollutants are detected in a long strip distribution, a pre-determined dragon formation can be selected; or if pollutants are detected in a large area, a pre-determined flag formation can be selected, etc. This invention is operated dynamically by personnel through a central control console based on on-site feedback. The long-distance air quality monitoring device 3 preferably uses infrared spectroscopy technology, enabling real-time monitoring of particulate matter, sulfur dioxide, nitrogen oxides (NOx), and heavy metal pollutants in the air after fireworks display. The sampling frequency is preferably 5-20 times / s.

[0110] Figure 4 This diagram illustrates a firefighting drone. When unburnt fireworks cause a fire, the firefighting drone 4, equipped with fire detectors, flame recognition cameras, and infrared thermal imaging cameras, can quickly locate the fire source and transmit the image information to the central control station 1, sending an alarm signal. Operators then fly the drone 4 over the fire source and use its onboard liquid and dry powder fire extinguishing bombs to initiate firefighting efforts and control the spread of the fire. Upon receiving the alarm signal from the central control station 1, firefighters quickly arrive at the scene to conduct firefighting and rescue operations.

[0111] This invention can absorb and eliminate pollution generated by fireworks in real time during fireworks displays, improving air quality. Air monitoring equipment can monitor and detect air pollution in real time. The drone control console can direct drone formations to move to heavily polluted areas for absorption and elimination. Firefighting drones can also quickly extinguish fires in the event of a fire, achieving the goal of integrated detection, prevention and firefighting, while taking into account environmental protection, safety and entertainment value.

[0112] The embodiments given above are preferred examples for implementing the present invention, and the present invention is not limited to the above embodiments. Any non-essential additions or substitutions made by those skilled in the art based on the technical features of the present invention are within the protection scope of the present invention.
