A Smart Lighting Multi-Network Fusion Adaptive Communication Method

Abstract

This invention discloses a multi-network fusion adaptive communication method for intelligent lighting, applied to intelligent lighting systems. The system communication links include at least two of the following: starlight, mesh, and DC power line carrier. Link status information is periodically collected, and a weighted evaluation is performed based on weight parameters to determine the target communication link according to a preset strategy. When communication conditions are not met, a switchover is performed. During the switchover process, control parameters are cached and the lighting output electrical parameters are kept constant. After the switchover is completed, parameters are synchronized and network configuration is updated. This invention achieves multi-link redundancy and seamless switching, improving system communication stability.

Description

Technical Field

[0001] This invention relates to the field of intelligent lighting control technology, and more specifically to an intelligent lighting multi-network fusion adaptive communication method. Background Technology

[0002] Existing intelligent lighting systems mostly use a single communication method, which is prone to problems such as communication interruption and signal interference under complex operating conditions. During multi-link switching, defects such as light fluctuation, parameter loss, and reliance on centralized gateway control are likely to occur. Especially in driverless DC power supply lighting scenarios, there is a lack of a seamless switching mechanism that integrates DC power line carrier and wireless communication, resulting in insufficient system reliability and environmental adaptability. Summary of the Invention

[0003] This invention aims to provide a multi-network integrated adaptive communication method for intelligent lighting, which realizes automatic monitoring, weighted evaluation and seamless switching of multiple communication links, thereby improving the communication stability and operational reliability of intelligent lighting systems.

[0004] The present invention adopts the following technical solution: A multi-network fusion adaptive communication method for intelligent lighting, applied to an intelligent lighting system, wherein the communication link includes at least two of the following: a star-flash communication link, a mesh communication link, and a DC power line carrier communication link; the method includes the following steps: S1: Collect link status information of the communication link according to a preset period. The link status information includes at least one of signal strength, transmission delay, data packet loss rate, link connectivity, signal-to-noise ratio, and bit error rate. S2: Based on a preset threshold and link priority strategy, the link status information is weighted and evaluated. Different communication links are configured with different weight parameters to determine the target communication link. S3: When the current communication link does not meet the communication conditions, a switching instruction is generated; S4: Execute link switching in response to the switching command, cache lighting control parameters during the switching process, and keep the electrical parameters of lighting output constant during the switching period; S5: After the switch is completed, the cached lighting control parameters are synchronized to the target communication link, and the system network configuration information is updated.

[0005] Furthermore, the link priority strategy is as follows: the star-flash communication link is used first; when the star-flash communication link does not meet the communication conditions, it is switched to the mesh communication link; when neither the star-flash communication link nor the mesh communication link meets the communication conditions, it is switched to the DC power line carrier communication link.

[0006] Furthermore, the weighted evaluation in step S2 is performed at a fixed period, which is between 10ms and 200ms.

[0007] Furthermore, the switching period in step S4 is no longer than one lighting dimming cycle, and the switching process does not restart the lighting terminal or reset the lighting control parameters.

[0008] Furthermore, the lighting control parameters include at least one of the following: switch status, dimming level, color temperature parameter, working mode, and timing configuration.

[0009] Furthermore, after the switchover is completed, the original communication link remains under monitoring and enters the backup link queue when communication conditions are met.

[0010] Furthermore, once the target communication link meets the communication conditions and continues for a preset duration, a link switchback operation is performed.

[0011] Furthermore, the lighting terminal can independently complete the collection, evaluation, and switching of link status without relying on the central gateway device.

[0012] Furthermore, the system supports external locking commands. Upon receiving a locking command, the system will use a designated communication link and stop automatic switching.

[0013] Furthermore, the DC power line carrier communication link uses DC power supply lines to transmit signals, and the signal transmission and power transmission share the same line. Attached Figure Description

[0014] Figure 1 This is a flowchart of the intelligent lighting multi-network fusion adaptive communication method of the present invention. Detailed Implementation

[0015] Example 1 Upon system power-on initialization, the lighting terminal simultaneously activates the starlight, Mesh, and DC power line carrier communication modules. The terminal collects signal strength, data loss rate, and connectivity status of each link every 50ms. Based on preset weight parameters, the status of each link is weighted and evaluated, and the target communication link is determined according to preset priority. If the current link does not meet communication conditions, a switch is executed. During the switch, lighting control parameters are buffered to maintain constant output electrical parameters, and the switch duration does not exceed one lighting dimming cycle. After the switch is completed, parameters are synchronized to the target link, and network configuration is updated. The original link is continuously monitored; it enters the standby queue when conditions are met and automatically switches back when conditions are met. The lighting terminal can independently complete link judgment and switching without gateway involvement, making it suitable for driverless DC-powered lighting systems.

[0016] Example 2 In industrial environments with strong electromagnetic interference, wireless communication is susceptible to disruption. The system uses DC power line carrier as the primary backup link, prioritizing the use of the wireless link. In the event of a wireless communication failure, the system switches to the DC power line carrier link without altering the lighting output, ensuring control continuity. Users can lock specific communication links using locking commands to meet the needs of special operating conditions.
