Description

Technical Field

[0001] This invention relates to the technical field of dimming power supply control, and in particular to a dimming power supply control method and system based on interconnection communication. Background Technology

[0002] Currently, in existing intelligent lighting systems, dimming control typically relies on a single dimming power supply to drive LED light sources in a designated lighting area. This makes it difficult to simultaneously accommodate multiple types of dimming devices and multiple power nodes in a distributed layout, resulting in significant limitations in system scalability, resource coordination, and multi-source linkage. When the dimming process requires coordinated output across multiple power supplies, existing solutions generally lack mechanisms for identifying differences in the capabilities of different power supplies and unified management strategies, leading to frequent issues such as inconsistent dimming response speeds and discontinuous brightness changes. Furthermore, existing systems struggle to obtain reliable operational feedback in a timely manner during dimming execution, making it impossible to effectively determine whether the real-time status has met the expected dimming target. They also lack the ability to automatically compensate and seamlessly switch in case of power supply anomalies or output deviations, resulting in lighting interruptions or unstable visual experiences. Summary of the Invention

[0003] To address the issues of insufficient scalability, inconsistent response, and low stability in existing intelligent lighting systems regarding multi-power supply coordination, real-time status determination, and abnormal switching, this application provides a dimming power supply control method and system based on interconnect communication.

[0004] A dimming power supply control method based on Internet communication, the method comprising: When a dimming command is detected, the pre-stored dimming device calibration information is called, and the corresponding target dimming configuration is calculated based on the dimming device calibration information and the target dimming parameters carried in the dimming command. Obtain the attribute information of the currently connected dimming power supply at the extended interface, and generate the corresponding power supply identification result based on the attribute information; Based on the power source identification results and the target dimming configuration, a corresponding power source hierarchy relationship is constructed, and the hierarchical dimming sequence among each dimming power source is determined based on the power source hierarchy relationship. According to the graded dimming sequence, dimming output commands corresponding to the target dimming configuration are sent to each dimming power supply one by one. Dimming feedback data is acquired in real time during dimming output, and the real-time state corresponding to the current moment during dimming output is calculated based on the dimming feedback data. The real-time state is compared with the target dimming configuration. If the real-time state meets the accuracy requirements of the target dimming configuration, the dimming system is controlled to end the current dimming operation. If the real-time state fails to meet the accuracy requirements of the target dimming configuration, or if any dimming power supply is detected to be abnormal during the dimming output, an alternative dimming power supply is determined according to the power supply hierarchy, and the incomplete dimming output command is remapped to the alternative dimming power supply until the real-time state meets the accuracy requirements of the target dimming configuration.

[0005] By adopting the above technical solution, the target dimming configuration is automatically generated after the dimming command is triggered. Combined with multi-power supply attribute recognition, hierarchical dimming sequence, real-time feedback verification and replacement execution of abnormal power supply, the dimming process is made continuous, controllable and self-recovering from start to finish, thereby significantly improving the dimming stability and system reliability in multi-power supply collaborative scenarios.

[0006] Preferably, the step of calculating the corresponding target dimming configuration based on the dimming device calibration information and the target dimming parameters carried in the dimming command includes: Extract the target dimming parameters carried by the dimming command, wherein the target dimming parameters include at least the target brightness parameter, the target dimming time, and the dimming curve type; Based on the dimming device calibration information, a corresponding nonlinear response model is established. The nonlinear response model is used to characterize the relationship between dimming brightness and output driving quantity. The target brightness parameter carried in the above is input into the nonlinear response model for nonlinear quantization conversion to generate the corresponding target brightness output; The target brightness output, the target dimming time, and the dimming curve type are input into a preset dimming generation function to generate the corresponding target dimming configuration.

[0007] By adopting the above technical solution and introducing the joint analysis of dimming device calibration information and target parameters, the user's simple dimming command can be converted into a target configuration that adapts to the actual driving characteristics, making the dimming process more predictable and accurate, and reducing brightness errors caused by nonlinear differences in the device.

[0008] Preferably, the step of inputting the target brightness output amount, the target dimming time, and the dimming curve type into a preset dimming generation function to generate a corresponding target dimming configuration includes: The target brightness output is determined as the dimming amplitude parameter, the target dimming time is determined as the time boundary of the dimming change process, and the dimming curve type is determined as the curve constraint condition describing the dimming change trend. Based on the preset dimming generation function, the dimming change process is expanded in the time domain, and the target output quantity corresponding to each discrete time point within the time boundary is calculated according to the dimming amplitude parameter and the curve constraint condition, so as to generate the corresponding target output quantity time series. Based on the target output time series, a corresponding target dimming configuration is generated.

[0009] By adopting the above technical solution, and by decomposing, expanding and discretizing the brightness, time and dimming curves, a target output sequence with complete time resolution can be generated, so that the subsequent dimming drive process can be executed according to a clear time trajectory, thereby obtaining a smoother, more consistent and controllable brightness change curve.

[0010] Preferably, the step of obtaining the attribute information of the currently connected dimming power supply at the expansion interface and generating the corresponding power supply identification result based on the attribute information includes: Determine the attribute information of the currently connected dimming power supply obtained at the expansion interface. The attribute information includes at least the output capability parameters, dynamic response parameters, and supported dimming curve types. Based on the dimming curve type, the corresponding dimming groups are divided; Based on the output capability parameters, a corresponding first priority sequence is generated in the corresponding dimming group; Based on the dynamic response parameters, a corresponding second priority sequence is generated in the corresponding dimming group; The first priority sequence and the second priority sequence in each dimming group are integrated to generate the corresponding power identification result.

[0011] By adopting the above technical solution, the system can accurately identify the suitability of each power supply in this dimming task by structurally extracting the power supply output capability, response speed, and supported dimming curves, sorting them within groups, and fusing multiple sequences. This lays a reliable foundation for subsequent hierarchical dimming scheduling.

[0012] Preferably, the step of determining the attribute information of the currently connected dimming power supply obtained at the expansion interface includes: Send the corresponding call request through the extended interface, and obtain the built-in database of each dimming power supply according to the call request; Based on the built-in database, obtain the output capability parameters and dimming curve type of the currently connected dimming power supply; Based on the reference terminal in the current area of ​​the dimming command, a corresponding three-dimensional reference coordinate system is constructed, and the projection reference plane of the three-dimensional reference coordinate system is determined. The dynamic response parameters of the currently connected dimming power supply are determined based on the distance between the spatial coordinate lines connecting each dimming power supply and the reference terminal on the projection reference plane.

[0013] By adopting the above technical solution, response indicators are derived from the geometric spatial relationship between the dimming power supply and the reference terminal, and attribute sets are formed by combining power supply database information. This enables the system to obtain a more objective, calculable and quantifiable evaluation of power supply capabilities, thereby improving the accuracy and applicability of dimming recognition.

[0014] Preferably, the step of constructing a corresponding power supply hierarchy based on the power supply identification result, and determining the hierarchical dimming order among the dimming power supplies based on the power supply hierarchy, includes: Determine the first sequence parameter value of each dimming power supply in the first priority sequence of the power supply identification result, and determine the second sequence parameter value in the second priority sequence of the power supply identification result; Based on the pre-obtained weight ratio, the first sequence parameter value and the second sequence parameter value are weighted and fused according to the weight ratio to generate the corresponding dimming adaptation value; Based on the dimming adaptation value, a set of target power supplies that meet the requirements of the target dimming configuration is selected from each of the dimming power supplies. The set of target power supplies includes light-emitting power supplies and redundant power supplies. Based on the target power supply set, construct the power supply hierarchy relationship of the region where the dimming command is currently located; Based on the power supply hierarchy and the target output time series in the target dimming configuration, the hierarchical dimming sequence of each target power supply is determined.

[0015] By adopting the above technical solution, the set of power supplies that meet the target dimming is selected by weighted fusion calculation of multi-sequence parameters, and then a hierarchical structure is used to generate a graded dimming sequence, so that the multi-power supply dimming coordination process is strategic and structured, thereby improving the execution efficiency and scheduling rationality of dimming tasks.

[0016] Preferably, the step of obtaining the weight ratio includes: Determine the scene mode of the area where the dimming command is currently located, including economy mode, safety mode, and performance mode; Based on the mapping relationship of the scenario patterns, the corresponding weight ratio is determined.

[0017] By adopting the above technical solution and introducing economic, safety, and performance modes into the parameter weight adjustment mechanism, the system can dynamically change the importance of different capability attributes according to the needs of the scenario, thereby achieving a more flexible dimming strategy selection that is more in line with the actual application requirements and improving the adaptability of the dimming process.

[0018] Preferably, the step of determining alternative dimming power supplies based on the power supply hierarchy includes: Based on the power supply hierarchy, determine the dimming adaptation value corresponding to each redundant power supply in the target power supply set; The redundant power supply with the highest dimming adaptation value is subjected to a safety test, and the corresponding test results are generated. If the test results indicate that the test is normal, the redundant power supply with the highest dimming adaptation value is determined as a replaceable dimming power supply. If the test results indicate that the test is abnormal, a new redundant power supply with the highest dimming adaptation value is determined and tested again until the test results indicate that the test is normal.

[0019] By adopting the above technical solution, and prioritizing and detecting redundant power supplies based on hierarchical relationships, the system can quickly and reliably find alternative execution nodes when power supply fails, achieving a stable, continuous dimming experience without significant brightness jumps, and greatly improving the system's fault tolerance.

[0020] Preferably, the step of generating the accuracy requirements of the target dimming configuration includes: Based on the target dimming parameters, the corresponding precision mapping table is called, and the corresponding preliminary requirements are matched according to the precision mapping table. Based on the scene mode of the current area where the dimming command is located, the initial requirements are dynamically corrected to generate corresponding accuracy requirements.

[0021] By adopting the above technical solution, the target accuracy requirements are generated by using the accuracy mapping relationship table and dynamically corrected in combination with the scene mode, so that the dimming termination condition has scene-based and adaptive capabilities, thereby ensuring that the dimming output meets the brightness quality requirements while avoiding over-correction, and achieving a more reasonable stop judgment.

[0022] A dimming power supply control system based on Internet communication, employing a dimming power supply control method based on Internet communication, the control system comprising: The dimming panel is provided in multiple ways. Each dimming panel has a built-in control unit and a wireless communication unit that communicate with each other. The wireless communication unit is used to realize interconnection and communication between dimming panels or between the cloud and the dimming panel. A dimming trigger sensor is provided, with at least one dimming trigger sensor connected to each dimming panel. A power driver module, wherein the power input terminal of the power driver module is connected to a dimming power supply, and the power output terminal of the power driver module is connected to one or more LED lights; When the dimming trigger sensor sends a trigger signal to the dimming panel, the dimming trigger sensor is determined as the reference terminal for generating power identification results. The control unit generates a corresponding dimming command based on the trigger signal and generates a corresponding dimming output command by parsing the dimming command. When the cloud sends a dimming command to the dimming panel, the dimming panel is identified as the reference terminal for generating power identification results, so that the control unit can parse the dimming command to generate a corresponding dimming output command.

[0023] By adopting the above technical solution, a unified system is formed by integrating dimming panels, dimming trigger sensors, power drive modules, and interconnection communication mechanisms. This enables a highly collaborative control link between multiple panels, sensors, and power supplies, thereby supporting distributed dimming management across regions and nodes and achieving intelligent and networked lighting control capabilities.

[0024] In summary, this application includes at least one of the following beneficial technical effects: This application constructs an interconnected communication control mechanism for collaborative operation of multiple dimming power supplies. Upon receiving a dimming command, the dimming system first automatically generates a complete and executable target dimming configuration based on the dimming device calibration information and the dimming target. It then obtains attribute data of each dimming power supply from an extended interface to identify its actual output capabilities and response characteristics. Based on the identification results and the dimming task requirements, it constructs a hierarchical relationship between the power supplies, thereby determining the execution order of each power supply in the dimming process. During actual dimming execution, the system issues dimming output commands to each power supply sequentially according to the hierarchical order and continuously collects feedback data to calculate the real-time dimming status, enabling the system to determine in real time whether the current output has converged to the target dimming configuration. When deviations occur or a power supply malfunctions during execution, the system automatically selects a substitute power supply based on the pre-constructed power supply hierarchy and seamlessly remaps the incomplete dimming process, ensuring the continuity and stability of the entire dimming process even in the event of power supply malfunctions. This interconnected dimming control link, which is based on target configuration generation, power capability identification, hierarchical allocation, real-time status verification, and fault switching, not only solves the problems of traditional systems being unable to uniformly manage multiple power supplies, inconsistent dimming responses, and failure to maintain lighting continuity under fault conditions, but also significantly improves the accuracy, reliability, and system scalability of the dimming process, realizing multiple functions such as multi-power supply collaborative dimming, real-time dynamic correction control, and cross-power supply fault-tolerant switching.

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] In one embodiment, such as Figure 1 As shown, this application discloses a dimming power supply control method based on Internet communication. The dimming power supply control method based on Internet communication includes: S10. When a dimming command is detected, the pre-stored dimming device calibration information is retrieved, and the corresponding target dimming configuration is calculated based on the dimming device calibration information and the target dimming parameters carried in the dimming command. The dimming device calibration information refers to a set of parameters pre-collected, archived, and uniformly formatted before the dimming system is installed or shipped, including the light output capability, drive response characteristics, nonlinear characteristics of brightness changes, and drive parameters provided by the manufacturer for each dimming device. This information ensures that the system can interpret the dimming command using a unified reference standard when executing dimming tasks. The target dimming parameters are dimming demand data sent by the user side or upper-level control system. They typically include the desired brightness level of the luminaire, the time required for dimming changes, and the expected type of brightness change curve, describing the final target state of the dimming task. The target dimming configuration is a complete dimming execution scheme obtained after the system receives the target dimming parameters and performs nonlinear compensation, dynamic curve matching, and time-series quantization based on the dimming device calibration information. It includes the target output value, brightness change trajectory, and corresponding time node arrangement at each moment during the dimming process, ensuring the dimming process is executable and consistent with engineering standards.

[0030] S20. Obtain the attribute information of the currently connected dimming power supply at the expansion interface, and generate the corresponding power supply identification result based on the attribute information. The attribute information is the device capability data reported by the dimming power supply to the system through the expansion interface, including its maximum supported output power, transient response speed, executable dimming curve type, and load-bearing capacity during operation, used to determine the adaptability of each power supply in the dimming task. The power supply identification result is a comprehensive judgment result formed by the system after analyzing, comparing, and sorting all attribute information. It reflects the role and usage priority of each dimming power supply in the current dimming scenario.

[0031] S30. Based on the power supply identification results and the target dimming configuration, construct the corresponding power supply hierarchy and determine the hierarchical dimming sequence among the dimming power supplies. The power supply hierarchy is a multi-power supply organization structure jointly generated based on the power supply identification results and the target dimming configuration. It clarifies which power supplies serve as primary execution nodes, which serve as auxiliary nodes, and the level of each power supply in the dimming task. The hierarchical dimming sequence is the dimming execution order determined based on the power supply hierarchy, enabling the system to gradually issue dimming commands to multiple dimming power supplies according to certain priority rules.

[0032] S40. According to the hierarchical dimming sequence, dimming output commands corresponding to the target dimming configuration are issued to each dimming power supply in turn. During the dimming output, dimming feedback data is acquired in real time, and the real-time state corresponding to the current moment during the dimming output is calculated based on the dimming feedback data. The dimming feedback data refers to the current, voltage, brightness response, or other operational information characterizing the dimming state collected by the system in real time during the dimming power supply output process, which is used to reflect the actual execution of the dimming process. The real-time state is the current dimming progress or current brightness level calculated based on the dimming feedback data, which characterizes the relationship between the actual light emission state of the system at a certain moment and the target state.

[0033] S50. Compare the real-time status with the target dimming configuration. If the real-time status meets the accuracy requirements of the target dimming configuration, control the dimming system to end the current dimming operation. If the real-time status fails to meet the accuracy requirements of the target dimming configuration, or if any dimming power supply is detected to be abnormal during dimming output, determine a substitute dimming power supply according to the power supply hierarchy, and remap the unfinished dimming output command to the substitute dimming power supply until the real-time status meets the accuracy requirements of the target dimming configuration. The accuracy requirement is the error limit that the system determines for the dimming process to meet the target dimming configuration. It is dynamically set according to task requirements or scene requirements to make the dimming termination conditions more reasonable. A substitute dimming power supply refers to another available power supply that can take over the task after a dimming power supply malfunctions, determined according to the power supply hierarchy. This power supply can continue to execute the unfinished dimming task if its capacity, response time, and load conditions meet the requirements. An incomplete dimming output instruction refers to a target dimming output request that is still in the task queue when the dimming power supply malfunctions and has not yet been executed. It needs to be reassigned to an alternative dimming power supply to ensure that the dimming process continues uninterrupted.

[0034] In this embodiment, after detecting a dimming command generated by the upper-layer system, the user side, or the detection trigger side, the control unit first uses preset dimming device calibration information to perform nonlinear compensation and curve matching on the target dimming parameters to generate a time-sequential and directly driveable target dimming configuration. Subsequently, the control unit actively polls each currently connected dimming power supply through an extended interface to obtain its output capability, response speed, and supported dimming curves, and calculates the adaptability of the power supply in the current dimming task based on these attributes, forming a power supply identification result reflecting the differences in the power supply's execution capability. The system further constructs a power supply hierarchy based on the identification result and the target dimming configuration, giving multiple power supplies a clear role division and execution structure in the upcoming dimming process. According to this hierarchy, the control unit sequentially issues dimming output commands to the power supplies and continuously collects dimming feedback data such as current, voltage, or brightness feedback from the power supply during execution, obtaining a real-time status characterizing the progress of brightness change through real-time calculation. The control unit continuously compares the deviation between the real-time status and the target dimming configuration, and determines whether the dimming process has reached the termination condition based on preset accuracy requirements. If the real-time status deviation is too large or a power supply malfunctions during execution, the system will immediately select a substitute power supply from the power supply hierarchy to execute the remaining unfinished dimming output, and perform real-time remapping of the task instructions. This seamless switching ensures the continuity and stability of the brightness change process. Dimming task allocation, status verification, and anomaly handling among power supplies are all achieved through a unified network communication link, enabling the system to maintain consistent dimming quality and highly reliable operation in a multi-power supply collaborative environment.

[0035] Furthermore, the step of calculating the corresponding target dimming configuration based on the dimming device calibration information and the target dimming parameters carried in the dimming command includes: S101. Extract the target dimming parameters carried by the dimming command. The target dimming parameters include at least the target brightness parameter, the target dimming time, and the dimming curve type. First, parse the data payload of the command and extract the target dimming parameters related to this dimming task according to the preset command parsing protocol. In engineering, this parsing process is usually completed by the decoder embedded in the control firmware. By scanning the identification field, parameter field, and verification field in the command frame structure byte by byte, the key parameters such as the target brightness parameter, the target dimming time, and the dimming curve type are located and converted into an internal format that can participate in subsequent calculations. For example, the brightness parameter is converted from a percentage form to an internally identified brightness level code, the dimming time is converted into a time-series variable in milliseconds, and the curve type is mapped to a curve index number that the system can recognize. S102. Based on the calibration information of the dimming device, a corresponding nonlinear response model is established. The nonlinear response model is used to characterize the correspondence between dimming brightness and output drive quantity. The establishment process of the nonlinear response model is usually completed during equipment deployment or production. By sampling the actual brightness generated by the dimming device under different drive current, drive voltage, or PWM duty cycle inputs step by step, a nonlinear function mapping of brightness output relative to drive quantity is obtained using methods such as multi-segment curve fitting, exponential function approximation, or piecewise linear interpolation. During operation, the control unit loads the fitting parameters, node data, or model coefficients generated in the calibration stage into memory and reconstructs them according to its internally defined model structure, so that the response model can provide the corresponding drive output quantity based on any brightness target in real-time calculation. Through the establishment of this model, the system can accurately reflect the hysteresis characteristics of the lamp in the low brightness range, the saturation characteristics in the high brightness range, and the non-uniform gain change in the intermediate range, thereby ensuring that subsequent dimming calculations are performed in a manner consistent with the actual physical output, and that brightness jumps or changes that do not conform to the visual experience are not caused by linear assumptions.

[0036] S103. The target brightness parameters carried in the input are fed into the nonlinear response model for nonlinear quantization conversion to generate the corresponding target brightness output. A nonlinear quantization conversion is performed by the electro-optic mapping relationship within the nonlinear response model. In engineering, this conversion process is usually completed by a calculation module containing multiple fitting functions. By searching the brightness node data, curve coefficients, or interpolation intervals within the model, and combining them with the input segment corresponding to the target brightness, the actual output driving quantity that can drive the lamp to achieve that brightness is calculated, such as the current setpoint, PWM duty cycle, or digital drive code value. Since the brightness response of the lamp itself has obvious nonlinear characteristics, this quantization conversion automatically corrects the saturation effect in the high brightness area and the hysteresis phenomenon in the low brightness area, making the output result closer to the actual electro-optic characteristics of the lamp, avoiding brightness jumps or unstable control due to simple linear conversion during actual dimming.

[0037] S104. Input the target brightness output, target dimming time, and dimming curve type into a preset dimming generation function to generate the corresponding target dimming configuration. In engineering, this function typically consists of a set of executable mathematical programming modules. By discretizing the time axis, the complete dimming time interval is divided into several continuous time slices. Based on the variation constraints corresponding to the dimming curve type, such as gradually increasing, linear, gradually decreasing, or accelerating curves, the function calculates the trend of dimming output change within each time slice. During the calculation process, the generation function interpolates or fits each time slice based on the final value of the target brightness output, ensuring that the brightness change presents a continuous, smooth transition that conforms to visual perception rules throughout the entire time range, avoiding undesirable phenomena such as brightness jumps, overshoot, or excessively rapid changes. The final generated target dimming configuration is a time sequence containing multiple discrete time nodes and corresponding output driving quantities.

[0038] Furthermore, the step of inputting the target brightness output, target dimming time, and dimming curve type into a preset dimming generation function to generate the corresponding target dimming configuration includes: S1041. The target brightness output is determined as the dimming amplitude parameter, the target dimming time is determined as the time boundary of the dimming change process, and the dimming curve type is determined as the curve constraint condition describing the dimming change trend. After obtaining the target brightness output, target dimming time, and dimming curve type, these three input parameters are first processed by internal semantic classification to adapt to the input requirements of the dimming generation function. The target brightness output is converted into a dimming amplitude parameter to describe the final brightness change amplitude, which serves as the upper or lower bound of the brightness change during the dimming generation process. The target dimming time is parsed as the time boundary of the dimming process to limit the start and end times of the brightness change, so that the generation function can distribute the output change within this time window. The dimming curve type is mapped to a curve constraint condition to describe the brightness change rate, change trend, or light perception transition law, and is indexed into the corresponding function template or curve coefficient dictionary within the control firmware.

[0039] S1042. Based on a preset dimming generation function, the dimming change process is expanded in the time domain. The target output at each discrete time point within the time boundary is calculated according to the dimming amplitude parameter and curve constraints, generating a corresponding target output time series. The preset dimming generation function is called to expand the entire dimming process in the time domain. This is typically done by dividing the target dimming time range into multiple discrete time points according to a fixed sampling period or dynamic sampling strategy, and calculating the corresponding target output at each time point based on the dimming amplitude parameter and curve constraints. This calculation process is implemented by the curve interpolation module, piecewise function evaluation module, or exponential / logarithmic change function within the generation function. By processing the constraints of different curve types, the brightness change exhibits different forms such as acceleration, deceleration, or linearity in time. The generation function calculates time-slice by time to form a target output sequence that gradually transitions from the initial brightness to the target brightness. Each data point in the sequence corresponds to an executable drive output, allowing subsequent dimming execution stages to strictly control brightness changes according to this time plan.

[0040] S1043. Generate the corresponding target dimming configuration based on the target output time series; perform structured encapsulation according to the drive format requirements of the dimming execution unit to generate a target dimming configuration that can be directly used for control; this configuration usually contains multiple time nodes and their corresponding output drive values, and is stored in a fixed format as a dimming execution list, instruction sequence, or time drive table, so that the dimming power supply can read and execute them one by one in time order during actual operation; when generating the configuration, the system also ensures the continuity of changes between time points and the executability of output values, avoiding undriveable abnormal values ​​or execution jitter caused by excessive time, so that the final dimming configuration can be executed stably and efficiently in engineering, ensuring that the actual brightness change is completely consistent with the target dimming curve.

[0041] Furthermore, the step of obtaining the attribute information of the currently connected dimming power supply at the extended interface and generating the corresponding power supply identification result based on the attribute information includes: S201. Determine the attribute information of the currently connected dimming power supply at the expansion interface. The attribute information includes at least the output capability parameters, dynamic response parameters, and supported dimming curve types. After entering the power supply identification process, the control unit will first perform an attribute read operation on all dimming power supplies connected to the expansion interface. This operation is usually completed using standardized device query commands or manufacturer protocols. The output capability parameters, dynamic response parameters, and supported dimming curve types are extracted from the internal registers or configuration tables of each power supply through the interface bus. The output capability parameters generally include the maximum output power, current drive range, or voltage regulation range. The dynamic response parameters are used to reflect the response delay or processing speed of the power supply after receiving the command, while the dimming curve type represents the power supply's ability to execute what kind of dimming change trajectory. By obtaining this attribute information, the system can grasp the basic operating characteristics of each power supply, providing structured input data for subsequent grouping, priority generation, and capability matching.

[0042] S202. Based on the dimming curve type, the corresponding dimming group is divided. After successfully reading the dimming curve type of each dimming power supply, the control unit will divide the power supplies that support the same dimming curve into the same dimming group, so that the subsequent priority evaluation is performed among power supplies with consistent curve capabilities, to ensure that the brightness change trend of different power supplies can remain consistent during the dimming task execution. In engineering, this grouping action is usually achieved by mapping the dimming curve type to a preset curve classification table, and establishing multiple power supply index lists based on the classification table, with each list representing a dimming group. This division not only improves the synchronization of the dimming process, but also avoids the situation where power supplies with different curve capabilities are mixed into the same control sequence, resulting in output trajectory mismatch.

[0043] S203. Based on the output capability parameters, generate a corresponding first priority sequence in the corresponding dimming group. For power supplies within the same dimming group, the control unit generates a corresponding first priority sequence based on their output capability parameters. This sequence is obtained by quantifying and sorting the maximum output power, load capacity, or continuous drive capability of each power supply. Typically, the sequence is arranged in descending order or from high to low adaptability, so that power supplies with higher output capabilities are given priority as the main execution node in dimming tasks. In engineering implementation, this priority generation process may involve linear weighted scoring, threshold filtering, or direct sorting according to rated power. This method forms a first priority sequence that reflects the performance differences of power supplies, providing a clear basis for subsequent task allocation.

[0044] S204. Based on the dynamic response parameters, a corresponding second priority sequence is generated in the corresponding dimming group. The control unit generates a second priority sequence based on the dynamic response parameters of each power supply in the dimming group. By sorting the response delay, processing speed, or physical link delay of each power supply between receiving the command and starting execution, a priority order from fast to slow response speed is obtained. In engineering, this process is usually achieved by sampling the command response confirmation time of the power supply or by converting the response speed index using the previously measured spatial projection distance, and converting it into a comparable value, thereby forming a second priority sequence that reflects the real-time response capability of the power supply. This allows the system to prioritize the power supply with stronger response capability when fast dimming or low-latency tasks are required.

[0045] S205. Integrate the first priority sequence and second priority sequence in each dimming group to generate the corresponding power supply identification result. After obtaining the first priority sequence and second priority sequence of each dimming group, the control unit integrates the two sorting results through weighted fusion, sequence cross-matching, or rule matching to generate the final power supply identification result. In engineering, this integration process usually combines output capability and response speed into a comprehensive score according to the requirements of the dimming task or preset weights, and re-sorts the power supplies based on the score, while retaining the grouping structure to form an identification result that can comprehensively reflect the adaptation value and usage priority of each power supply in the current dimming task. This result ultimately serves as the basis for constructing the power supply hierarchy and dimming command allocation strategy, enabling the entire dimming execution process to have a structured, quantifiable, and interpretable power supply selection basis.

[0046] Furthermore, such as Figure 3 As shown in the diagram, A, B, C, and D correspond to dimming power supply drivers A, B, C, and D in the upper part of the diagram, respectively. The step of determining the attribute information of the currently connected dimming power supply at the expansion interface includes: S2011. The control unit sends a corresponding call request through the extended interface and obtains the built-in database of each dimming power supply based on the call request. When initiating the attribute acquisition process, the control unit first broadcasts a standardized call request to all connected dimming power supplies through the extended interface. This request can be constructed according to the manufacturer's protocol or a system-defined protocol and sent in frame structure via the bus. After receiving the call request, the power supply returns its internally stored capability data, curve support information, and device identification information to the control unit in the form of a database or parameter block. After receiving the response data, the control unit verifies, parses, and caches the data frame to obtain the built-in database of each dimming power supply. This database contains the basic capability information required for subsequent identification calculations and is a key data source for power supply grouping, priority ranking, and dynamic response calculation.

[0047] S2012. Based on the built-in database, obtain the output capability parameters and dimming curve type of the currently connected dimming power supply. The control unit extracts the key parameters required for this task from the built-in database returned by each power supply. These include output capability parameters describing the maximum drive capability, rated power range, or continuous current output capability of the dimming power supply, as well as data characterizing which dimming curve types the power supply supports, such as ramp-up, ramp-down, S-curve, or linear curve types. These parameters are typically obtained through field indexes in the database, such as power supply capability fields, curve index fields, or curve support bitmaps. By parsing these parameters, the control unit can clearly understand the executability of each power supply in the dimming task, providing an accurate basis for subsequent grouping and priority generation.

[0048] S2013. Based on the reference terminal of the current area where the dimming command is located, construct a corresponding three-dimensional reference coordinate system and determine the projection reference plane of the three-dimensional reference coordinate system. The control unit will determine a reference terminal as a reference according to the current location of the dimming command area, and use the physical installation position or spatial coordinate point of the reference terminal as the origin of the three-dimensional coordinate system. Further define the positive directions of the X-axis, Y-axis and Z-axis according to the layout direction of the lamps and the position of the installation surface, thereby constructing a three-dimensional reference coordinate system for distance calculation. Subsequently, the system will further determine its corresponding projection reference plane according to the geometric characteristics of the lighting area or the engineering construction drawings. Usually, the XY plane can be selected as the standard projection plane for the spatial relationship between lamps, so that the subsequent calculation of the spatial distance between the power supply and the reference terminal can be performed in a unified dimension, improving the comparability of response parameters and the stability of calculation.

[0049] S2014. Based on the distance between the spatial coordinate lines connecting each dimming power supply and the reference terminal on the projection reference plane, determine the dynamic response parameters of the currently connected dimming power supply. The control unit will acquire the spatial position coordinates of each dimming power supply in the three-dimensional coordinate system and construct a spatial coordinate line connecting the reference terminal position to the power supply. Then, project the line onto the projection reference plane and calculate the length of the projection line through vector projection operation or geometric projection formula. This length is used as one of the key factors characterizing the response speed of the power supply physical link. Since the transmission distance of the control signal and the response delay are usually positively correlated in the actual lighting environment, this projection distance can be used as an important quantitative indicator of the dynamic response parameters of the dimming power supply. The control unit finally calculates the dynamic response parameters of each power supply based on this distance, so that the subsequent priority calculation is more consistent with the actual delay characteristics in the same dimming area.

[0050] Furthermore, the steps of constructing a corresponding power supply hierarchy based on the power supply identification results, and determining the hierarchical dimming sequence among the dimming power supplies based on the power supply hierarchy, include: S301. Determine the first sequence parameter value of each dimming power supply in the first priority sequence of the power supply identification results, and determine the second sequence parameter value in the second priority sequence of the power supply identification results. After obtaining the power supply identification results, the control unit first extracts the first sequence parameter value in the first priority sequence and the second sequence parameter value in the second priority sequence for each dimming power supply. These parameter values ​​are usually comparable values ​​that have been standardized and quantified based on the power supply's output capability and dynamic response capability, such as power score, drive capability index, or response speed index. The control unit extracts the two parameter values ​​corresponding to each power supply into the internal calculation cache by indexing and retrieving the sequences in the identification results, so as to perform comprehensive calculations on power supply adaptability later. By extracting these two sequence parameters, the system can fully grasp the performance characteristics of each power supply before the dimming task is executed, providing basic indicator data for subsequent weight fusion and hierarchical division.

[0051] S302. Based on the pre-acquired weight ratios, the first sequence parameter values ​​and the second sequence parameter values ​​are weighted and fused according to the weight ratios to generate a corresponding dimming adaptation value. After obtaining the sequence parameter values ​​of each power supply, the control unit weights and fuses the first sequence parameter values ​​and the second sequence parameter values ​​according to the pre-stored weight ratios to form a dimming adaptation value describing the overall dimming capability of the power supply. In engineering, this fusion calculation typically adopts a linear weighting method, where the internal mathematical operation unit performs a weighted summation of the two parameters according to preset weights, and then performs normalization processing as needed to make parameters of different dimensions comparable under the same scoring system. The weight ratios can be dynamically adjusted according to the dimming scenario, user preferences, or system configuration. For example, the weight of dynamic response parameters can be increased in scenarios requiring fast response, while the weight of output capability parameters can be increased when performing high-power dimming tasks in high-brightness areas. The final dimming adaptation value is the core indicator for determining whether each power supply is suitable for performing the current dimming task.

[0052] S303. Based on the dimming adaptation value, a target power supply set that meets the requirements of the target dimming configuration is selected from all dimming power supplies. The target power supply set includes emitting power supplies and redundant power supplies. The control unit filters each power supply based on its dimming adaptation value to determine whether it meets the execution requirements of the target dimming configuration. These requirements include whether it has a power margin sufficient to meet the target brightness output capability, whether it supports the dimming curve type in the target dimming configuration, and whether its dimming adaptation value reaches the execution threshold. Power supplies that meet these conditions are included in the target power supply set. The power supplies in this set are further divided into emitting power supplies and redundant power supplies based on their adaptability. The emitting power supplies are used to actually perform the dimming task, while the redundant power supplies act as backup nodes to take over the remaining tasks when the main power supply fails. This selection process makes the dimming execution structure more stable and reliable, ensuring that the dimming task can be undertaken by power supplies with sufficient capacity and response speed.

[0053] S304. Based on the target power supply set, construct the power supply hierarchy for the current region where the dimming command is located. After obtaining the target power supply set, the control unit constructs the corresponding power supply hierarchy based on the dimming adaptation value, functional positioning (luminous or redundant) of the power supplies within the set, and their spatial relationship with the dimming region. This hierarchy is typically stored internally by generating a hierarchical structure diagram, priority linked list, or role mapping table. The power supply with the highest adaptation value is placed at the top of the hierarchy and primarily undertakes the dimming task. Power supplies with the second highest adaptation value but meeting the requirements are arranged below it, while redundant power supplies are set as backup layer nodes for immediate switching in case of power failure or performance abnormalities. This hierarchy forms the organizational structure in a multi-power supply dimming scenario, enabling subsequent dimming commands to be allocated according to a clear hierarchical order.

[0054] S305. Based on the power supply hierarchy and the target output time series in the target dimming configuration, determine the hierarchical dimming sequence of each target power supply. The control unit, based on the constructed power supply hierarchy and the target output time series in the target dimming configuration, determines the execution order and participation method of each target power supply in the dimming process. The system allocates dimming tasks starting from the top-level power supply according to the priority of the hierarchical structure, assigning it responsibility for the key brightness range in the target output sequence. Secondary power supplies, within their capabilities, handle certain time periods or participate in brightness compensation as support nodes. Redundant power supplies do not directly participate in dimming output but will take over corresponding tasks at any time when the execution deviation or abnormality of the main power supply is detected. This hierarchical dimming sequence ensures that the dimming process is executed in a structured manner, with stable brightness changes, consistent response speed, and maintains the continuity and reliability of the dimming process even in the event of power supply abnormalities.

[0055] For example, in a large exhibition hall lighting area, four dimming power supplies participate in the same dimming task. After completing attribute identification, the system obtains the first and second sequence parameter values ​​for each power supply. Power supply A has the highest output capability but a medium response speed; power supply B has the fastest response speed but a slightly lower output capability; power supply C has a medium capability but a slightly slower response; and power supply D has the lowest capability and can only serve as a backup node. The system first extracts the capability score and response score of these four power supplies from the power supply identification results, and loads the corresponding weight ratio according to the "performance mode" currently used in the exhibition hall. The capability score weight is set to 0.6, and the response score weight is set to 0.4. The two types of scores of the four power supplies are weighted and fused to finally obtain the comprehensive dimming adaptation value: power supply A is 0.88, power supply B is 0.84, power supply C is 0.63, and power supply D is 0.31. Subsequently, power supplies A, B, and C, whose adaptation values ​​are 0.6 higher than the task threshold, are included in the target power supply set. A and B are identified as luminous power supplies due to their high adaptation values ​​and sufficient capacity, while C is identified as a redundant power supply. Power supply D is not included in the set due to insufficient adaptation value. The system constructs a power supply hierarchy for the exhibition hall area based on the adaptation values, placing power supply A at the highest level, power supply B as a secondary execution node, and power supply C as a backup node. Finally, following the logic of S305, the system allocates the main execution interval of brightness changes to power supply A based on the target output time series in the target dimming configuration. Some local time periods requiring rapid response are assigned to power supply B for auxiliary execution, while power supply C remains on standby monitoring the execution process. If A or B deviates, it can immediately take over the unfinished dimming interval, thus ensuring that the entire exhibition hall dimming process remains continuous, stable, and highly fault-tolerant under multi-power supply collaboration.

[0056] Furthermore, the steps for obtaining the weight ratio include: Determine the scene mode of the area where the dimming command is currently located. Scene modes include economy mode, safety mode, and performance mode. Based on the mapping relationship of the scenario patterns, the corresponding weight ratios are determined.

[0057] In this embodiment, before entering the power adaptability calculation process, the control unit first determines the appropriate scenario mode based on the spatial region to which the dimming command belongs, the usage scenario of that region, and the operating strategy already set by the upper-level system. For example, it enters the economy mode in energy-sensitive areas, the safety mode in areas with high requirements for lighting stability, and the performance mode in scenarios requiring fast response or outstanding visual effects. After identifying the corresponding scenario mode, the system queries the weight configuration corresponding to that mode from a pre-stored scenario mapping table. The economy mode typically increases the importance of output capability to reduce unnecessary high power allocation, the safety mode increases the weight of response speed or device health status to reduce the risk of failure, and the performance mode prioritizes response speed and curve execution capability to ensure the smoothness and real-time performance of the dimming process. After obtaining the weight ratio of the mode, the control unit writes it into the subsequent adaptability calculation process, so that the capability scores and response scores of different power supplies can reflect the performance preferences of the current scenario when fused, thereby keeping the power selection strategy dynamically consistent with the actual lighting needs.

[0058] For example, in a multi-zone lighting system in an office building, a dimming command is received for the conference room area to smoothly increase its brightness from 10% to 60%. After parsing the command, the control unit automatically determines the scene mode to be a safe mode based on the current discussion state and the high requirement for lighting stability in this area. Once the safe mode is determined, the system immediately reads the weight ratio corresponding to the "safe mode" from a preset scene mapping table. This mode typically sets a higher weight for dynamic response parameters, such as setting the response speed weight to 0.7 and the output capability weight to 0.3, so that the system prioritizes power supplies with fast response and stable execution in subsequent multi-power supply adaptation calculations. Thus, during dimming, if two power supplies with similar output capabilities exist, the one with the faster response speed will receive a higher dimming adaptation value and be prioritized for task allocation, ensuring a smooth and stable brightness change in the conference room. In another corridor area, when the system identifies that the area is currently in energy-saving operation, it switches the scene mode to economy mode and applies a mapping ratio where the output capacity weight is higher than the response weight. This prioritizes the use of lower-power or lower-operating-cost power supplies for dimming tasks, achieving overall energy consumption optimization. By dynamically adjusting the weight ratio according to the scene mode, the multi-power supply dimming system can adaptively match the usage needs of the area, satisfying both the lighting experience and ensuring safety and energy efficiency.

[0059] The table below shows examples of initial values ​​for each scenario mode (which can be adjusted by the user): Furthermore, the step of determining alternative dimming power supplies based on power supply hierarchy includes: S501. Based on the power supply hierarchy, determine the dimming adaptation value corresponding to each redundant power supply in the target power supply set. After entering the alternative power supply screening process, the control unit first searches for all redundant power supplies in the target power supply set according to the established power supply hierarchy, and reads the dimming adaptation value corresponding to each redundant power supply from the hierarchy structure. This adaptation value serves as a core indicator for measuring whether a redundant power supply can successfully take over the main execution task, reflecting its comprehensive characteristics such as output capability, dynamic response speed, and curve execution capability. The control unit caches the dimming adaptation values ​​of all redundant power supplies in the internal sorting module, providing a quantitative data foundation for subsequent priority selection and safety testing, enabling the system to quickly locate the most capable alternative power supply node in a structured manner when a power supply anomaly occurs.

[0060] S502. The redundant power supply with the highest dimming adaptation value undergoes a safety test, generating corresponding test results. If the test results indicate normal operation, the redundant power supply with the highest dimming adaptation value is identified as a replaceable dimming power supply. If the test results indicate abnormal operation, a new redundant power supply with the highest dimming adaptation value is identified and tested until the test results indicate normal operation. After obtaining the dimming adaptation values ​​of each redundant power supply, the control unit performs safety tests on them sequentially in descending order of adaptation value. In engineering practice, this test typically includes rapid detection of the power supply's current operating status, output stability, line health, and communication link reliability. Test results are generated by sending lightweight probe commands to the power supply, reading its transient feedback, or detecting its internal status register. When the test results indicate that the redundant power supply is operating normally and has the ability to take over the current dimming task, the control unit immediately identifies it as a replaceable dimming power supply and directly enters the task takeover process. If the test results indicate that the power supply is abnormal or cannot meet the takeover conditions, the system will select the next redundant power supply with the highest dimming adaptability value according to the sorting results and re-execute the above test process. This process is repeated until a redundant power supply that has passed the test is found, so as to ensure that the dimming task still has a reliable backup execution node in the event of failure or performance abnormality of the main execution power supply.

[0061] Furthermore, the step of generating the accuracy requirements for the target dimming configuration includes: Based on the target dimming parameters, the corresponding precision mapping table is called, and the corresponding preliminary requirements are matched according to the precision mapping table. Based on the scene mode of the current area where the dimming command is located, the initial requirements are dynamically corrected to generate the corresponding accuracy requirements.

[0062] In this embodiment, after obtaining the initial accuracy requirements, the control unit dynamically corrects these requirements based on the current scene mode. This correction process is implemented in engineering through an internal parameter adjustment model. This model adjusts the key indicators in the initial accuracy requirements—including the allowable brightness error range, error convergence speed, steady-state stability threshold, and brightness change smoothness—according to the weight configuration corresponding to the scene mode. Specifically, in safety mode, a stricter scaling factor is applied to error-related indicators, tightening the upper and lower limits of the allowable error by a fixed ratio and increasing the weight of the parameter corresponding to the convergence speed, enabling the system to more quickly detect anomalies when the state deviates. In performance mode, the error limits are kept unchanged or slightly relaxed, but the weight of the dynamic response item is increased, making the system focus more on the real-time performance and smoothness of brightness changes when determining dimming completion. In economy mode, the control unit applies a relaxation coefficient to the steady-state accuracy threshold according to an energy-saving strategy, eliminating the need for repeated fine-tuning to extremely high precision during the dimming process, thereby reducing power load fluctuations. The accuracy requirements after correction are written into the dimming status determination module by the control unit for subsequent real-time status comparison, ensuring that the termination conditions of the dimming process are consistent with the current region's operating strategy and have execution constraints that can be implemented in engineering.

[0063] A dimming power supply control system based on Internet communication, employing a dimming power supply control method based on Internet communication, the control system comprising: There are multiple dimming panels 1. Each dimming panel 1 has a built-in control unit and a wireless communication unit that communicate with each other. The wireless communication unit is used to realize interconnection and communication between dimming panels 1 or between the cloud and dimming panels 1. Dimming trigger sensor 2, with at least one dimming trigger sensor 2 connected to each dimming panel 1; The power driver module 3 has its power input terminal connected to the dimming power supply and its power output terminal connected to one or more LED lights 4. When the dimming trigger sensor 2 sends a trigger signal to the dimming panel 1, the dimming trigger sensor 2 is determined as the reference terminal for generating power identification results. The control unit generates the corresponding dimming command according to the trigger signal mapping, and generates the corresponding dimming output command by parsing the dimming command. When the cloud sends a dimming command to the dimming panel 1, the dimming panel 1 is designated as the reference terminal for generating power identification results, so that the control unit can parse the dimming command to generate the corresponding dimming output command.

[0064] In this embodiment, the entire dimming power supply control system uses the dimming panel 1 as the core of control and communication. Each dimming panel 1 integrates a control unit and a wireless communication unit. The control unit is responsible for parsing trigger signals or cloud commands and generating specific dimming output commands. The wireless communication unit is used to establish interconnection communication links between multiple dimming panels 1 or between dimming panels 1 and the cloud, realizing cross-regional dimming coordination. In terms of structural connection, each dimming panel 1 is connected to at least one dimming trigger sensor 2. The dimming trigger sensor 2 maintains real-time communication with the panel through communication lines or short-range signals. When the dimming trigger sensor 2 detects user operation or changes in ambient light, it transmits a trigger signal to the dimming panel 1, and the trigger sensor is designated by the system as the reference terminal for the current dimming task. The reference terminal serves as the coordinate origin for subsequent attribute information acquisition. Its spatial position is used to construct a three-dimensional reference coordinate system so that the system can calculate the distance of the dimming power supply on the projection reference plane based on the spatial connection between the dimming power supply and the reference terminal, thereby generating dynamic response parameters used to distinguish the speed of power supply response. When the dimming command originates from the cloud, the dimming panel 1, which directly issues the dimming command from the cloud, is designated as the reference terminal. Its fixed position and known orientation can also serve as a reference for the spatial coordinate system, used to calculate the dynamic response parameters of all currently connected dimming power supplies. In the system execution path, the reference terminal's role is not only as a trigger point for behavior but also as a geometric reference for the attribute information acquisition process. This allows the control unit to extract the output capability parameters and dimming curve type of each dimming power supply and generate power supply identification results by combining the dynamic response parameters. Finally, the dimming power supply drives the LED lamp 4 to perform the corresponding dimming action through the power drive module 3. The power drive module 3 is electrically connected to the dimming power supply and provides a stable drive current to the LED lamp 4, enabling the dimming output command to be accurately mapped into a controllable change in light output, thus forming a complete distributed dimming action chain. The reference terminal serves as the spatial reference origin for the system when acquiring dimming power supply attribute information. Its role extends beyond triggering the initial action of the dimming task; more importantly, it provides a unified and quantifiable geometric coordinate reference for calculating dynamic response parameters. When the dimming trigger sensor 2 sends a trigger signal to the dimming panel 1, the physical location of this sensor is designated by the system as the reference terminal for the current dimming task. The control unit constructs a three-dimensional reference coordinate system based on this location and determines a projection reference plane for calculating the response distance. This allows the system to calculate the projection distance of the spatial connection between each dimming power supply and the reference terminal on the projection reference plane after acquiring their spatial coordinate information. This projection distance is strongly correlated with the link stability, signal propagation delay, and feedback update speed of the dimming power supply in the wireless communication network. Therefore, it is used as an engineering metric for dynamic response parameters to describe the response speed of each dimming power supply when performing a dimming task. When the dimming command originates from the cloud system, the dimming panel 1, which directly issues the dimming command from the cloud, is set as the reference terminal. Its position also serves as the origin of the three-dimensional coordinate system, used to calculate the dynamic response parameters of all connected dimming power supplies. Through this method based on a fixed geometric reference point, the reference terminal ensures that in complex environments with multiple panels and multiple dimming power supplies, the system can generate power supply identification results with a consistent judgment mechanism, laying a unified parameter foundation for subsequently constructing power supply hierarchical relationships and executing graded dimming.
