It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0038] like Figure 1 As shown, the present invention proposes a distributed lighting scene application method based on Bluetooth mesh, comprising the following steps:

[0039] S1. Build a Bluetooth Mesh network, start the network configuration program through the central node, add node devices to the Bluetooth Mesh network one by one, ensure that each node device is successfully connected to the central node, and establish stable network communication;

[0040] Network configuration operations include:

[0041] Select a central node as the gateway device, and also act as the host to coordinate the work between nodes;

[0042] Start the network configuration program through the central node and add node devices to the Bluetooth Mesh network one by one.

[0043] S2, pixel units constitute a complete image, each node displays a part of the complete picture, composed of 1 or more pixel lamp controllers, generally PWM type controllers are composed of one pixel unit, addressable (WS2811) lighting controllers, composed of multiple pixels to form a pixel unit;

[0044] The pixel units that make up a complete image include:

[0045] The pre-displayed image is divided into a form composed of pixel units. For different types of light controllers, each part of the image is mapped to the corresponding node device according to the composition rules of its pixel units.

[0046] S3. Prepare resources in advance. Since the image content files of lights are large in size, they can be downloaded to the control center in advance. In this way, when playing the effects, the central equipment only needs to publish key scheduling information to realize the flow of the picture.

[0047] Pre-resource preparation includes:

[0048] The segmented image content files are pre-stored in the controller of the central node and each node device.

[0049] S4, dynamic picture display, when the equipment is fully ready, the central device will publish update events at a fixed time. After receiving the published events, other nodes will update their lighting effects to realize the changes of static pictures and display the effects of dynamic pictures.

[0050] Dynamic screen display includes:

[0051] Set a timed release cycle for update events at the central node, and determine the appropriate release cycle based on the required animation effect frame rate;

[0052] The central node publishes update events regularly according to the set period. After receiving the event, the node device updates its own lighting effects in time according to the pre-stored image resources and the received scheduling information to realize the display of dynamic pictures.

[0053] A distributed lighting scene application system based on Bluetooth mesh, including:

[0054] A central node (gateway), Bluetooth Mesh function, acts as a gateway and host to coordinate the work between nodes.

[0055] The central node is the core of the system, with Bluetooth Mesh function, acting as a gateway and host.

[0056] It is responsible for coordinating and managing the entire distributed lighting scene, including the network configuration operation of node devices and the synchronization of lighting effects.

[0057] The central node is also responsible for receiving instructions from the control center and scheduling node devices according to these instructions to achieve dynamic display of lighting effects.

[0058] Multiple node devices with Bluetooth Mesh function act as lighting controllers to display lighting effects.

[0059] These devices also have Bluetooth Mesh capabilities, which can receive instructions from the central node and control the lighting effects based on the instructions.

[0060] Each node device can be one or more pixel lamp controllers, responsible for displaying part of the lighting scene.

[0061] The node device can be a PWM type controller or an addressable (such as WS2811) light controller, with multiple pixels forming a pixel unit.

[0062] A control center is used to store image content files and publish key scheduling information to achieve the flow of images.

[0063] The Control Center is responsible for managing and preprocessing light image content files, which are usually large in size.

[0064] It downloads the image content files to the central node and the controllers of each node device in advance, so that only key scheduling information needs to be released during playback, thereby achieving the flow and dynamic effects of the picture.

[0065] A timed publishing mechanism is used to set a period for publishing update events at a central node.

[0066] This mechanism allows the central node to set an appropriate publishing period (such as 40ms) according to the required animation effect frame rate (such as 25FPS).

[0067] It ensures that the central node can publish update events regularly to maintain the consistency and smoothness of the lighting effects.

[0068] The central node and node devices communicate with each other via a Bluetooth Mesh network.

[0069] Bluetooth Mesh network communication:

[0070] The communication between the central node and node devices is entirely based on the Bluetooth Mesh network, which allows multi-point communication and large-scale coverage in distributed scenarios.

[0071] The low power consumption characteristics of Bluetooth Mesh networks are suitable for smart home and IoT scenarios, ensuring the energy efficiency and reliability of the system.

[0072] The control center can pre-store the image content files in the controllers of the central node and each node device.

[0073] Pre-storage of image content files:

[0074] The control center stores the segmented image content files in advance in the controllers of the central node and each node device in order to reduce delays and improve response speed during playback.

[0075] This pre-storage mechanism enables the node devices to respond quickly and update the lighting effects when the central node releases scheduling information, achieving smooth display of dynamic images.

[0076] The timed publishing mechanism can determine a suitable publishing cycle according to the required animation effect frame rate, and control the central node to publish update events at a regular time.

[0077] Dynamic screen display:

[0078] The system can realize the transition from static images to dynamic images. The central node publishes update events regularly, and the node devices update their own lighting effects according to the pre-stored image resources and the received scheduling information.

[0079] This dynamic display is not only suitable for simple lighting changes, but can also achieve complex animation effects, such as long-distance street light animation, lighting rhythm changes between different floors / buildings, etc.

[0080] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the appended claims, or the equivalent forms of such scope and boundaries.
