[0002] With the rapid development of smart sports and the cultural tourism night economy, basketball courts are no longer limited to competition and fitness functions, but also take on the role of interactive entertainment and artistic lighting performances. Traditional basketball goal-triggered lighting control solutions include mechanical switches or pressure sensors and visual recognition. Mechanical switches or pressure sensors install pressure plates on the base of the basket or the ground, triggering the controller when the basketball hits the ground or makes an impact. Visual recognition (Camera + Algorithm) uses a camera to capture real-time images of the basketball entering the basket and identifies the goal through image processing algorithms.

[0003] The aforementioned existing technologies generally suffer from the following drawbacks: mechanical and vision solutions are easily affected by environmental interference, and are mostly single-point switches, making it impossible to balance missed detections and false detections; different stages often require multiple controllers or relays, resulting in complex intermediate conversions and high maintenance costs; and it is difficult to achieve multi-channel and diversified lighting and animation linkage based on existing hardware.

In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions. The described embodiments are some embodiments of this application, but not all embodiments. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0031] Figure 1 This is a schematic diagram of a basketball light and shadow interactive device based on infrared detection according to an embodiment of the present invention. The basketball light and shadow interactive device based on infrared detection includes:

[0032] A high-precision infrared detection module 100 includes multiple infrared beam sensor units installed below the basket ring. The illumination angle of the multiple infrared beam sensor units covers the multi-angle ring area of ​​the basket. The high-precision infrared detection module 100 generates an entry signal and transmits the entry signal to the intelligent controller 200.

[0033] The intelligent controller 200 has a built-in embedded processor. The intelligent controller 200 receives the frame entry signal generated by the high-precision infrared detection module 100. The embedded processor is equipped with a preset template, a preprocessing unit and a filtering unit. The embedded processor generates a light operation instruction package based on the frame entry signal and the preset template and sends it.

[0034] The distributed control network includes a master controller 300 and a sub-controller 400. The master controller 300 and the sub-controller 400 are arranged in a star or tree topology. The master controller 300 receives the lighting operation command packets and is equipped with a parsing unit. The parsing unit parses the lighting operation command packets, converts them into channel signals, and sends them to the sub-controllers 400. The sub-controllers 400 are connected to a lighting group 500 in a cascaded manner and output the lighting operation command packets to the lighting group 500.

[0035] Lighting group 500 is connected to sub-controller 400 by signal. Lighting group 500 controls the opening and closing of lights or the playback of light and shadow program effects according to the instructions in the lighting operation instruction package, so as to display light and shadow effects.

[0036] Specifically, multiple infrared beam sensor units cover the multi-angle ring area of ​​the basketball hoop, and combined with an adaptive gain algorithm, they identify the sphere's obstruction and send the ball's entry signal to the intelligent controller 200.

[0037] The intelligent controller 200 receives frame entry signals from multiple infrared beam sensor units, performs preprocessing and filtering on the frame entry signals, and judges the frame entry event in real time according to the frame entry judgment algorithm. The embedded processor is equipped with a preset template, and the intelligent controller 200 maps the judged frame entry event into a light operation instruction packet according to the preset template.

[0038] The high-precision infrared detection module 100 is a key component used to detect whether a basketball has entered the hoop. It has high-precision detection capabilities and can accurately capture relevant information during the basketball movement.

[0039] Multiple infrared beam sensor units comprise multiple infrared beam sensors, each consisting of a transmitter and a receiver. The transmitter emits infrared light, and the receiver receives this light. When an object blocks the infrared light, the intensity of the light received by the receiver changes, thus detecting the object's presence. Multiple such sensor units are combined to form the basis of detection.

[0040] Multiple infrared beam sensor units cover the multi-angle ring area of ​​the basketball hoop.

[0041] Multi-angle ring coverage: Multiple infrared beam sensor units are arranged around the basketball hoop, providing surround coverage from different angles and positions. The purpose of this is to ensure that the basketball is detected by at least one infrared beam sensor unit regardless of the direction it enters the hoop, avoiding blind spots and improving the comprehensiveness and accuracy of detection.

[0042] Adaptive Gain Algorithm: Factors such as ambient light intensity, the material and color of the basketball all affect the light intensity received by the infrared beam sensor unit. The adaptive gain algorithm automatically adjusts the sensor's gain parameters according to different environmental conditions and detection scenarios. When the ambient light is strong, the gain is appropriately increased to enable the sensor to detect changes in light more sensitively; when the ambient light is weak, the gain is reduced to avoid excessive interference to the sensor.

[0043] Ball Occlusion Detection: When a basketball enters the hoop and blocks infrared light, the intensity of the light received by the infrared beam sensor unit changes. An adaptive gain algorithm analyzes and processes this change to determine if the occlusion is caused by the basketball. By comprehensively analyzing data from multiple sensor units, the occlusion situation can be accurately identified, confirming whether the basketball has entered the hoop.

[0044] The high-precision infrared detection module 100, after identifying the sphere's obstruction, sends the basket-entry signal to the intelligent controller 200 in a specific data format. The intelligent controller 200, the control core of the entire device, receives the basket-entry signal and further processes and analyzes this data to determine whether a basketball basket-entry event has occurred, and generates corresponding instructions based on preset rules.

[0045] Furthermore, nodes can be added or removed according to the size of the site without major circuit or cabinet modifications, and it has plug-and-play characteristics.

[0046] Furthermore, the inbound event includes the object identifier that entered the box, the time of entry, and the specific location of the box.

[0047] Furthermore, the adaptive gain algorithm is optimized by incorporating machine learning algorithms. By collecting a large amount of data on the occlusion of infrared light by basketballs in different scenarios, the model is trained, enabling the adaptive gain algorithm to automatically adjust the gain parameters according to different ambient light, basketball speed and direction, and other factors, thereby further improving the recognition accuracy of ball occlusion.

[0048] In one embodiment, the light operation instruction packet is a UDP / TCP light operation instruction packet, which supports multiple data formats and encryption verification.

[0049] Furthermore, the lighting operation instruction package is a programmable lighting operation instruction package.

[0050] In one embodiment, the intelligent controller 200 converts the optical signal of the frame entry signal transmitted by the high-precision infrared detection module 100 into an electrical signal via a photodiode.

[0051] In one embodiment, the preset template is configured with an entry animation template corresponding to the electrical signal of the entry signal, an entry animation playback speed, and entry animation color parameters.

[0052] In one embodiment, the light operation instruction package includes an entry animation template corresponding to the entry signal, an entry animation playback speed, and entry animation color parameters.

[0053] In one embodiment, the main controller 300 internally stores multiple sets of light and shadow program effect templates, which can be remotely switched or triggered at time through the intelligent controller 200. The sub-controller 400 is connected to LEDs or light strips of various colors. The LEDs or light strips receive the frame-entry animation template, frame-entry animation playback speed, frame-entry animation color parameters, and selected light and shadow program effect template signals from the light operation instruction package. Through the set signal mapping engine, according to the predefined light operation instruction package signal mapping rules, the lighting group 500 is driven to control the opening and closing of the lights or the playback of light and shadow program effects, and execute the pre-programmed light and shadow effects.

[0054] Among them, the light and shadow program effect templates include goal effect and consecutive goal effect.

The LED or light strip displays the frame-entry animation template, frame-entry animation playback speed, frame-entry animation color parameters, and selected light and shadow program effect template in the light operation instruction package through the single triggering mode and the continuous triggering mode.

[0060] In one embodiment, the intelligent controller 200 uses a local area network, is configured with a static IP address and has port verification enabled, and uses virtual local area network isolation.

[0061] The intelligent controller 200 has a built-in CRC check unit and a simple encryption unit to ensure that the instructions are not tampered with during transmission;

[0062] The intelligent controller 200 transmits data with the high-precision infrared detection module 100 and the main controller 300 using standard interfaces and protocols.

[0063] In one embodiment, preprocessing and filtering include removing ambient light interference and generating trigger pulses using an adaptive threshold algorithm;

[0064] The frame entry event judgment includes setting a signal persistence event threshold and an occlusion area threshold. An embedded algorithm is used to determine whether the current signal persistence event is within the signal persistence event threshold and whether the current signal occlusion area is within the occlusion area threshold.

[0065] The lighting operation instruction package includes animation templates, playback speed, and color parameters.

[0068] Step S102: Determine whether the current frame entry signal is within the signal duration event threshold and the occlusion area threshold according to the frame entry determination algorithm. If it is within the signal duration event threshold and the occlusion area threshold, map the frame entry signal into a light operation instruction packet containing light control according to the preset template.

[0069] In step S103, the lighting operation command packet is transmitted to the main controller 300 via network transmission. The main controller 300 outputs the command to the sub-controller 400, and the sub-controller 400 coordinates the execution with the lighting group 500.
