[0037] The backend communicates with the control terminal and the backend, and is used to store, preview, and download the launch data.

[0038] Preferably, the communication module adopts a combination of LoRa, ZigBee, GPSpps, mesh and Bluetooth modules to ensure stable communication and reliable ignition. The communication module supports BLEmesh and relay gateway communication, and provides real-time feedback of voltage and ignition status to the mobile APP.

[0039] Preferably, the ignition module includes a multi-protocol interface, adapting to fireworks products with various ignition methods.

[0040] Preferably, the base further includes: a magnetic, pin, suction cup, and cable tie fixing device for fixing the base to a plane or vertical surface.

[0043] Preferably, the base is also provided with LED lights.

[0044] Preferably, the facade is formed by a wire mesh suspended by a drone or a vertical firing rack.

[0045] The above-mentioned intelligent fireworks display system includes the following steps:

[0046] Step 1: The user downloads the ignition project data, including patterns and text, through the control terminal. The data is transmitted to the transfer control box, which parses and generates an ignition timing file and broadcasts it to the base.

[0047] Step 2: Control the drone to take off and fly to the target point to project the infrared marker base placement position;

[0048] Step 3: The bases are automatically or manually sorted according to the marked positions; after sorting, the LED lights are turned on to preview the firing effect;

[0049] Step 4: If the rehearsal is successful, the control terminal issues an ignition command, and the base executes the ignition.

[0050] Step 5: Use a drone to photograph and record the fireworks display effect.

[0051] Preferably, the network is automatically sorted based on the order in which the networks are formed.

[0052] Preferably, the data of the fireworks display project is exported as a KML file and imported into the drone control system. The handle controls the drone to fly directly above each base on the pattern to form a firing point, pauses for 10 seconds, and projects the data onto the ground using its built-in infrared or laser. The base is then placed at the projection point to position the base and fireworks.

[0053] This embodiment takes a heart-shaped fireworks display as an example. The intelligent fireworks display system of this invention uses a built-in smartphone app for control, and a 4G network for communication with the smartphone via a relay box. The heart shape is divided into 300 equal points, therefore 300 bases are used for the display. The display process includes the following steps: The user selects and downloads a heart-shaped pattern through the app and generates an ignition file. The ignition file includes a fireworks product list, operation procedures, display images, and audio files. The number of fireworks products matches the display item. A KML file is exported to a drone. The drone's RTK differential positioning system is used to fly to the target point and project heart-shaped infrared markers. The heart shape is divided into 300 equal points. The operator places the fireworks bases on the ground. The placement of the graphic firing points is determined based on infrared markers. The firing points are automatically sorted according to the network's sequence; for example, if 300 points are to be fired, the drone positions itself on 300 bases. Through communication with a repeater box, the drone sorts the points according to the network sequence of the bases. The firing timeline within each base requires all 300 fireworks to be ignited within one second. Data packets from the 300 points are synchronized and parsed. The drone receives KML files; the patterns are first merged into a single line using CAD, then divided into equal points, and finally exported to third-party software to generate a KML map information document. KML files are geographic modeling information files stored in Keyhole Markup Language (KML), a Geographic Information System (GIS) data format based on XML. KML files describe and store geographic information such as landmarks, points, lines, polygons, and images. They can be used to identify and label locations, create different camera angles, overlay textures, and add HTML content (links, font styles, etc.). After sorting, the firing effect is previewed by illuminating LED lights.

[0054] After the rehearsal was passed, the control terminal issued an ignition command, and the bases ignited the fireworks one by one. The 300 bases ignited the fireworks one by one from front to back with a time difference of 0.2 seconds. The drone captured the fireworks display and recorded the effect.

[0055] In this embodiment:

[0056] Base: Integrates GPS / ZigBee positioning module, magnetic fixing device, expansion interface and BLE communication unit, with one dual-color LED light to display status and simulate use. The specific structure of the base can refer to the fireworks display base disclosed in CN222364479U. The distance between the bases can reach 50 meters. Each base has a power switch. After the power is turned on under the drone, it will automatically identify and sort the network with the relay box. The base is also equipped with 3 expansion interfaces for connecting to the ignition of traditional fireworks, but all connections are through a relay.

[0057] See Figure 1The repeater box in this embodiment includes a 4G module, a GPS module, a wireless module, an audio and power amplifier module, and a display module. It supports 4G / BLEmesh communication, has audio synchronous output and high-precision timing control functions, and has a communication distance of <=500 meters with each base. It has GPS positioning function with a positioning accuracy of 10 meters, is powered by a lithium battery, has a USB interface for charging, a 28x64 OLED display for battery level, and has a built-in 5W dual-channel output and an external audio output.

[0058] This utility model system is based on a drone, equipped with an infrared / laser projector and a 4K camera to achieve dynamic positioning and effect feedback; it uses a mobile phone as the control terminal, with a built-in APP and communication connection backend: supporting pattern design, remote control and data optimization; the repeater box has an interval ignition timing accuracy of 5ms±1ms and a maximum communication distance of 500 meters; the base expansion port supports the connection of three traditional igniters and displays the status in real time through dual-color LEDs; the drone supports importing KML map files, flies along a preset trajectory and projects positioning marks.

[0059] In this embodiment of the invention, the specific process of achieving high-precision positioning by combining UAV infrared / laser projection marking technology in the "heart-shaped pattern 300 ignition" scenario is as follows:

[0060] 1. Base Station Setup and Initialization

[0061] Base station deployment: Set up RTK base stations near the firing area (such as within a safe distance) to ensure coverage of the entire heart-shaped pattern.

[0062] Data connection: The base station communicates with the drone in real time via 4G / 5G or radio link to transmit differential correction data (carrier phase observations).

[0063] Coordinate calibration: Input the geodetic coordinate system (such as WGS-84) of the firing area, and complete the initial positioning calibration through static observation of the base station, with an accuracy of millimeters.

[0064] 2. UAV RTK positioning and flight path planning

[0065] Drone configuration:

[0066] It is equipped with an RTK positioning module (mobile station), an infrared / laser projector, and a 4K camera.

[0067] It receives differential data from the base station and corrects its own positioning error in real time, achieving centimeter-level accuracy (≤5cm).

[0068] Importing KML files:

[0069] Users can convert the heart-shaped pattern into a KML file (containing the latitude and longitude coordinates of 300 equally divided points) through the control terminal APP.

[0070] Importing a KML file into the drone flight control system automatically generates a flight path, with each marker point corresponding to a preset position of a firework base.

[0071] 3. Dynamic projection of marker points by drones

[0072] Flight and hovering:

[0073] The drone flies sequentially along the KML path to directly above each marker point and hovers for 2-10 seconds (adjusting according to ambient wind speed).

[0074] RTK positioning ensures that the drone's hovering position error is ≤5cm.

[0075] Infrared / laser projection:

[0076] The drone uses a laser or infrared device to project bright markers (about 10cm in diameter) onto the ground to mark the precise placement of the fireworks base.

[0077] The projection position strictly corresponds to the coordinates in the KML file, and the error is corrected in real time by RTK.

[0078] 4. Adaptive positioning and correction of the fireworks base

[0079] Base positioning module:

[0080] Each firework base has a built-in GPS / ZigBee positioning module to receive location information from markers projected by the drone.

[0081] The base corrects its position in real time using RTK differential data (via drone) or a local ZigBee mesh network.

[0082] Placement and matching:

[0083] The operator places the base near the marked point, and the base uses LED indicators (red / green) to indicate the position matching status.

[0084] Green light: Position error ≤ 5cm (meets requirements).

[0085] Red light: You need to manually adjust it until the green light comes on.

[0086] 5. Network sequencing and pre-drill verification

[0087] Automatic networking:

[0088] The base automatically forms a network based on the order of the marked points (the order of 300 points in the KML file) to generate the ignition timing logic.

[0089] Network information is uploaded to the control terminal APP via a repeater box (4G / 5G+BLEMesh).

[0090] LED preview:

[0091] The control terminal issues a pre-simulation command, and all the base LED lights light up sequentially according to the ignition sequence to simulate the heart-shaped pattern firing effect.

[0092] The drone's camera captures real-time footage of the rehearsal, which is then compared with the expected pattern in the control app to confirm there are no discrepancies.

[0093] 6. Ignition Execution and Closed-Loop Feedback

[0094] High-precision timing control:

[0095] The relay control box parses the ignition timing file and broadcasts the ignition command with an accuracy of 5ms ± 1ms.

[0096] The 300 bases are ignited sequentially at 0.2-second intervals to ensure the continuity of the dynamic display of the heart-shaped pattern.

[0097] Effect verification:

[0098] The drone captured the entire fireworks display and transmitted the footage back to the control center in real time via a 4K camera.

[0099] The system automatically compares the actual firing effect with the preset pattern and generates a closed-loop verification report.

[0100] This utility model system is easy to use, effectively improves the efficiency and positioning accuracy of fireworks placement, and has a closed-loop verification of the setting effect, solving the inefficiency and error of traditional manual measurement; from path planning and marker projection to base calibration, it reduces manual intervention and ensures that the setting effect meets expectations 100%.

[0101] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
