Description

Technical Field

[0001] The present application relates to the technical field of distribution boxes, and in particular to a scheduling method, system and distribution box for multi-channel LED power output. Background Art

[0002] With the continuous development of LED lighting technology, LED distribution boxes specifically designed for LED lighting have emerged. Compared to traditional LED distribution boxes, which are designed for industrial frequency AC power, they cannot meet the requirements of LEDs for low-voltage DC power supply, precise dimming, and multi-circuit independent control. Early LED distribution boxes were primarily used in lighting projects and urban construction. With the development of the Internet of Things (IoT), they have gradually evolved towards intelligent and modular design.

[0003] LED distribution boxes integrate multiple functional modules to expand their application scenarios. The voice module supports voice commands, such as "turn on emergency lighting," enabling rapid responses through voice interaction. This is particularly suitable for environments like computer rooms and unmanned base stations. Sensor modules such as light, temperature, and humidity monitor environmental parameters in real time. Combined with the dimming module, they automatically adjust LED brightness, for example, reducing power to save energy when sunlight is sufficient. The flexible combination of these modules elevates the LED distribution box from a single power distribution device to an intelligent control hub, widely used in building intelligence, landscape lighting, and other fields.

[0004] Existing LED distribution boxes use a fixed branch design. When the LED branch load in a certain area suddenly increases, the redundant power of other low-load branches cannot be automatically transferred, resulting in the risk of local overload. Summary of the Invention

[0005] In order to enable power sharing among multiple LED power outputs, the present application provides a scheduling method, system and distribution box for multiple LED power outputs.

[0006] In a first aspect, the present application provides a method for scheduling multi-channel LED power output, which adopts the following technical solution:

[0007] A method for scheduling multi-channel LED power output includes the following steps:

[0008] Based on a plurality of LED branches powered by the first power module, obtaining branch powers corresponding to the LED branches;

[0009] Calculating a power average of a plurality of branch powers;

[0010] If the power average value is greater than a preset first reference value, the number of the LED branches whose branch powers are less than the power average value is calculated as a first number; and the number of the other LED branches is calculated as a second number;

[0011] If the first number is greater than the second number and the second power module is not started, start the second power module, control the second power module to power the other LED branches, and cut the other LED branches out of the first power module;

[0012] If the first number is greater than the second number and the second power module has been started, activating the connected power distribution branch in standby mode; the power distribution branch is used to connect to the idle power module;

[0013] If the power average value is greater than a preset second reference value, issuing a search instruction;

[0014] Based on the search instruction, searching for an idle power module in a waiting state on the power distribution branch; wherein the second reference value is greater than the first reference value;

[0015] If the idle power module is found, the power distribution branch is switched from the standby mode to the power mode, and the idle power module is switched from the waiting state to the power supply state; a third number of other LED branches are controlled to be electrically connected to the idle power module, and the LED branches electrically connected to the idle power module are cut out of the second power module;

[0016] If the idle power module is not found, a full load prompt is issued.

[0017] By adopting the above technical solution, the power of each LED branch is obtained in real time and the average value is calculated, which is used as a basis to trigger different levels of scheduling strategies: when the power average value exceeds the first reference value and the number of low-load branches is greater than the number of high-load branches, if the second power module is not enabled, it will be activated to take over the high-load branch to avoid overloading the first power module; if the second power module is already working, the backup distribution branch will be activated. When the power average value exceeds the higher second reference value, a further search for idle power modules is carried out, and after activation, the high-load branches are redistributed to achieve flexible power flow between multiple modules. This hierarchical scheduling mechanism greatly improves the system power utilization, reduces the risk of local overload, and improves the load capacity of the LED distribution box; at the same time, based on the redundant design of the backup modules and distribution branches, the system fault tolerance is enhanced, and rapid switching can be performed to ensure power supply continuity in the event of a fault; and this method relies on the existing circuit architecture, does not require extensive modification, and reduces deployment costs.

[0018] Optionally, the step of switching the idle power module from the waiting state to the power supply state includes the following sub-steps:

[0019] Obtaining the type, real-time output power, and adjustable power upper limit of the idle power module;

[0020] When the type of the idle power module is the same as the type of the first power module, calculating the required supplementary power value according to the real-time power requirements of the third number of LED branches;

[0021] The required supplementary power value is smaller than a preset ratio threshold of the adjustable power upper limit, and a first ratio power of the adjustable power upper limit is used as the output power of the idle power module to power the third number of LED branches.

[0022] By adopting the above technical solution, when the idle power module and the first power module are of the same type, it generally means that they have similar high-power output capabilities and stability. In this case, allocating power at the higher first ratio can quickly and efficiently meet the high power requirements of the third number of LED branches.

[0023] Optionally, the step of switching the idle power module from the waiting state to the power supply state includes the following sub-steps:

[0024] Obtaining the type, real-time output power, and adjustable power upper limit of the idle power module;

[0025] When the type of the idle power module is the same as the type of the second power module, calculating the required supplementary power value according to the real-time power requirements of the third number of LED branches;

[0026] The required supplementary power value is less than a preset proportion threshold of the adjustable power upper limit, and a second proportion power of the adjustable power upper limit is used as the output power of the idle power module to power the third number of LED branches; wherein the second proportion is less than the first proportion.

[0027] By employing this technical solution, the second power module is typically used for auxiliary power supply or for specific low-power demand scenarios. When the idle power module is of the same type, power is allocated at the lower second ratio, precisely matching the potential low-power requirements of the third number of LED branches. This prevents overpowering, reduces unnecessary energy consumption, and ultimately lowers the operating cost of the entire system.

[0028] Optionally, the step of controlling a third number of other LED branches to be electrically connected to the idle power module includes the following sub-steps:

[0029] Acquire the real-time power of the idle power module in real time;

[0030] If the real-time power is within the first preset range, the size of the third number is adjusted according to the real-time power of the idle power module, the lower the real-time power is, the larger the third number is; the higher the real-time power is, the smaller the third number is;

[0031] If the real-time power is within the second preset range, the third quantity is less than or equal to a set value.

[0032] By adopting the above technical solution, when the real-time power of the idle power module is within the first preset range and is relatively low, it indicates that the module has a large power margin available for use. At this time, according to the rule that the lower the real-time power, the larger the third number, increasing the number of LED branches connected to it can allow the idle power module to carry more load, avoid idleness and waste of power resources, fully tap its power potential, and improve the energy utilization efficiency of the entire power output system. If the real-time power is high, it indicates that the idle power module is close to its power upper limit. According to the principle that the higher the real-time power, the smaller the third number, reducing the number of LED branches connected to it can prevent damage or failure of the power module due to overload, ensure that the power module operates within a safe operating range, and extend its service life.

[0033] Optionally, the step of searching for an idle power module in a waiting state on the power distribution branch includes the following sub-steps:

[0034] If the idle power modules are found, the number of the idle power modules found is counted as the idle number;

[0035] The first reference value is adjusted inversely according to the idle number. The larger the idle number is, the smaller the first reference value is; and the smaller the idle number is, the larger the first reference value is.

[0036] By adopting the above technical solution, when the number of idle power modules is large, it means that there are more idle power modules available for deployment in the system. In this case, reducing the first reference value will cause the system to trigger the power scheduling mechanism more frequently. Because a lower first reference value makes it easier for the average power value to exceed the threshold, the system will initiate power adjustments to high-load LED branches earlier, allocating power to these high-load branches. This fully utilizes idle power modules, avoids resource waste, and improves the power utilization of the entire system. If the number of idle power modules is small, it indicates that the number of idle power modules available for deployment in the system is limited. Increasing the first reference value will prevent the system from easily triggering power scheduling and will only take action when the average power value reaches a high level. This avoids excessive scheduling when there are insufficient idle power modules, ensuring that the existing power modules can stably power the LED branches and preventing system instability caused by excessive scheduling.

[0037] Optionally, the method further comprises the following steps:

[0038] Obtaining power parameters of all distribution branches in the same power bus to which the LED branch belongs; the power parameters include the power transmitted on each branch and the total power in the same power bus;

[0039] Calculate the power output percentage of all distribution branches based on the power parameters = the total power transmitted on each branch / the total power in the same power bus;

[0040] The second reference value is adjusted inversely according to the power output percentage; the greater the power output percentage, the smaller the second reference value; and the smaller the power output percentage, the larger the second reference value.

[0041] By adopting the above technical solution, when the power output percentage is low, it indicates that the overall power output of the distribution branches within the local area network still has significant room for improvement. Increasing the second reference value at this time means that the system will only trigger subsequent operations such as searching for idle power modules at a higher average power level. This allows the system to more fully tap the power potential of existing distribution branches under the current power allocation, allowing them to bear more load and avoid premature activation of backup resources, thereby improving power resource utilization efficiency. If the power output percentage is high, it means that the distribution branch is operating near full capacity. At this time, lowering the second reference value will make the system more sensitive to power changes and begin searching for idle power modules when the average power level is low. This allows backup resources to be activated in a timely manner, ensuring that the power requirements of the LED branches are met and preventing the normal operation of the LEDs from being affected by overloading of the existing distribution branches.

[0042] Optionally, the step of issuing a search instruction includes the following sub-steps:

[0043] Based on the search instruction, a signal generator is controlled, wherein the signal generator emits a high-frequency square wave signal corresponding to the search instruction;

[0044] Based on a preset modulation method, the high-frequency square wave signal is modulated with the DC power signal of the distribution branch;

[0045] transmitting the modulated signal through a DC power transmission line of a distribution branch;

[0046] Extract and purify the high-frequency square wave signal modulated on the DC power signal, and demodulate the high-frequency square wave signal;

[0047] The demodulated digital signal is decoded and processed to extract data information related to the search instruction for controlling the power output of the LED branch.

[0048] By adopting the above technical solution, a high-frequency square wave signal is modulated onto the DC power transmission line, so that data information can be carried while power is transmitted, thereby realizing the integrated transmission of power and communication without laying additional communication lines.

[0049] Optionally, the step of issuing a search instruction includes the following sub-steps:

[0050] Based on the search instruction, a signal generator is controlled, wherein the signal generator emits an AC carrier signal of a specific frequency and amplitude corresponding to the search instruction;

[0051] Converting the search instruction into a low-frequency data signal to be modulated;

[0052] Based on a preset AC modulation method, the low-frequency data signal is modulated with the AC carrier signal;

[0053] coupling the modulated AC signal to the AC power transmission line of the distribution branch;

[0054] extracting a modulated AC signal from the AC power signal;

[0055] Demodulate the extracted and purified AC signal to restore the original low-frequency data signal;

[0056] The demodulated signal is decoded and processed to extract data information related to the search instruction for controlling the power output of the LED branch.

[0057] By adopting the above technical solution, the search instructions are converted into signals that can be transmitted on the AC power transmission line of the distribution branch through AC modulation, realizing the integration of power and communication. It can accurately extract data information for controlling the power output of the LED branch, improve system scheduling efficiency, reduce communication costs and enhance the level of intelligent control.

[0058] In a second aspect, the present application provides a multi-channel LED power output scheduling system, which adopts the following technical solutions:

[0059] A scheduling system for multi-channel LED power output includes a processor, wherein the processor executes the steps of any one of the above-mentioned scheduling methods for multi-channel LED power output.

[0060] In a third aspect, the present application provides a distribution box, which adopts the following technical solution:

[0061] A distribution box includes a housing, wherein a circuit board, a power drive element, an expansion compartment, a power module, a communication module, and a processor are arranged in the housing;

[0062] The circuit board includes a basic function module and an onboard remote control function module; the circuit board is provided with an antenna, power supply ports of different voltages, and a communication interface for connecting to an expansion function board;

[0063] The power driving element includes a magnetic latching relay, which is electrically connected to the circuit board; a reverse driving circuit is provided on the circuit board;

[0064] Expansion compartment, used to connect expansion function boards;

[0065] The power supply module includes a first power module, a second power module and a power distribution branch, wherein the first power module and the second power module are respectively used to supply power to multiple LED branches; the power distribution branch is used to connect to the idle power module;

[0066] The communication module is controlled by the processor and transmits the search instruction and obtains the power output of the control LED branch by superimposing the corresponding search instruction with the power signal of the power distribution branch;

[0067] A processor, wherein the processor executes the steps of the above-mentioned method for scheduling the power output of multiple LEDs, and is used to issue a search instruction.

[0068] To summarize, this application includes at least one of the following beneficial technical effects: improving system power utilization, reducing the risk of local overload, and increasing the load capacity of LED distribution boxes; enhancing system fault tolerance and ensuring power supply continuity; relying on existing circuit architecture to reduce deployment costs; achieving precise power distribution and reducing energy consumption; and improving system scheduling efficiency, reducing communication costs and enhancing the level of intelligent control through integrated power and communication transmission.

[0076] Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings.

[0077] Throughout this specification, reference to the terms "certain embodiments," "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiments or examples are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0078] The present application embodiment discloses a scheduling method for multi-channel LED power output, referring to Figure 1 and Figure 2 , including the following steps:

[0079] Based on multiple LED branches powered by the first power module, the branch power corresponding to the LED branches is obtained. By setting a power monitoring element, such as a power sensor, in the circuit, the power data of each LED branch is collected in real time. This data will serve as the basis for subsequent power scheduling.

[0080] Calculate the average power of multiple branches; the average value can reflect the current overall power consumption level of multiple LED branches and is an important reference indicator for judging the system power status.

[0081] If the average power value is greater than a preset first reference value, the number of LED branches with branch power less than the average power value is calculated as a first count; the number of other LED branches is calculated as a second count. The preset first reference value is a power threshold set based on system design requirements and actual operating experience, used to determine whether the system is under a relatively high power load. When the average power value exceeds this threshold, the power of each LED branch is further analyzed, and the number of branches with power less than the average power value is counted as the first count, and the number of branches with power greater than or equal to the average power value is counted as the second count.

[0082] If the first number is greater than the second number and the second power module is not activated, the second power module is activated and controlled to power the remaining LED branches, disconnecting the remaining LED branches from the first power module. If the number of low-load branches exceeds the number of high-load branches and the second power module is not activated, this indicates that the first power module may be at risk of overload. In this case, the second power module is activated and the high-load LED branches are switched to the second power module for power supply, thus sharing the load on the first power module, preventing damage due to overload and ensuring stable system operation.

[0083] If the first number is greater than the second number and the second power module is already started, the connected distribution branch in standby mode is activated; the distribution branch is used to connect to the idle power module. When the second power module is already running, but there are still many low-load branches and few high-load branches in the system, it means that the two existing power modules may not be enough to meet the system's power requirements. At this time, the standby distribution branch is activated to prepare for the connection of the idle power module, thereby further increasing the system's power supply capacity. Under normal circumstances, the standby distribution branch is in standby mode and does not participate in power transmission. Once activated, it can quickly connect to the idle power module to achieve power replenishment.

[0084] If the average power value exceeds a preset second reference value, a search command is issued. Based on the search command, a search is conducted on the power distribution branch for idle power modules in a waiting state. The second reference value is greater than the first reference value. The second reference value, which is greater than the first reference value, represents a higher power threshold. When the average power value exceeds the second reference value, it indicates that the system's power demand has further increased, requiring more proactive measures to meet it. At this point, a search command is issued to begin searching for idle power modules on the power distribution branch for additional power support.

[0085] If an idle power module is found, the power distribution branch is switched from standby mode to power mode, and the idle power module is switched from a standby state to a power supply state. A third number of other LED branches are electrically connected to the idle power module, and the LED branches electrically connected to the idle power module are disconnected from the second power module. The power distribution branch is searched for an idle power module. If a successful search is made, the standby power distribution branch is activated to a normal operating power mode, and the idle power module is simultaneously activated and put into a power supply state. Then, based on the actual system conditions, a certain number (a third number) of high-load LED branches are connected to the newly activated idle power module, and these branches are disconnected from the second power module, redistributing power among the multiple power modules, further optimizing the system's power distribution to meet high-load demands.

[0086] If no idle power modules are found, a full load warning is issued. If no idle power modules are found after the search, it means that the system currently has no additional power resources to call upon. At this time, a full load warning is issued to remind the operator that the system has reached the power limit and needs to take appropriate measures, such as reducing the load or adding power devices, to avoid system failure due to overload.

[0087] The power of each LED branch is acquired in real time and the average value is calculated, which is used as a basis to trigger different levels of scheduling strategies. This progressive scheduling mechanism significantly improves system power utilization, reduces the risk of local overloads, and increases the load capacity of the LED distribution box. At the same time, the redundant design of idle power modules and distribution branches enhances the system's fault tolerance, allowing rapid switching to ensure power supply continuity in the event of a fault. This method relies on the existing circuit architecture, eliminating the need for extensive modifications and reducing deployment costs.

[0088] Reference Figure 2 and Figure 3 The step of switching the idle power module from the waiting state to the power supply state includes the following sub-steps:

[0089] Comprehensive information about idle power modules is required, including their type, real-time output power, and adjustable power ceiling. The type of idle power module is a crucial characteristic, as different types can vary significantly in power output capability, stability, and applicable scenarios. Real-time output power reflects the module's actual current output power, while the adjustable power ceiling defines the maximum additional power the module can provide while maintaining safe and stable operation. Advanced sensor technology and data acquisition systems enable accurate acquisition of these key parameters.

[0090] If the type of the idle power module is the same as that of the first power module, this indicates that the two power modules have a high degree of similarity in performance and characteristics. This means that they have similar high-power output capabilities and stability. In this case, the required supplemental power value needs to be accurately calculated based on the real-time power requirements of the third number of LED branches. This is achieved by monitoring the real-time power consumption of each LED branch in real time. These power values ​​are then aggregated to obtain the total real-time power requirement. Combined with the current output power of the first and second power modules, the additional supplemental power required to ensure normal operation of the third number of LED branches is calculated. For example, assuming the third number of LED branches is five, and their real-time power requirements are P1, P2, P3, P4, and P5, respectively, the total real-time power requirement, PtotalDemand, = P1 + P2 + P3 + P4 + P5. Then, based on the output power of the first and second power modules, the required supplemental power value, Psupplement, is calculated as PtotalDemand - (the current output power of the first power module + the current output power of the second power module).

[0091] After calculating the required supplemental power value, it needs to be compared with the preset proportional threshold of the adjustable power upper limit. The preset proportional threshold is a key parameter set based on system design requirements and safety considerations. It ensures that the safe operating range of the idle power module is not exceeded when it is used. If the required supplemental power value is less than the preset proportional threshold of the adjustable power upper limit, it means that the idle power module has sufficient capacity to provide the required additional power. At this time, the first proportional power of the adjustable power upper limit is used as the output power of the idle power module to power the third number of LED branches. For example, a first proportional power of 80% is selected. Because the idle power module is of the same type as the first power module and has similar high-power output capability and stability, allocating power at the higher first proportional ratio can quickly and efficiently meet the potential high power requirements of the third number of LED branches.

[0092] This ensures that when the idle power modules are put into use, reasonable power allocation can be carried out according to actual conditions, giving full play to the role of the idle power modules and ensuring the stable and efficient operation of the entire LED lighting system.

[0093] The step of switching the idle power module from a waiting state to a power supply state includes the following sub-steps:

[0094] After the system determines that an idle power module needs to be put into use, it obtains relevant information about the idle power module, including its type, real-time output power, and adjustable power limit. The module type determines key factors such as its power characteristics, applicable scenarios, and compatibility; the real-time output power reflects the module's current operating status; and the adjustable power limit specifies the maximum additional power the module can provide while maintaining safe and stable operation. Advanced sensor technology and an intelligent monitoring system enable real-time and accurate collection of this information.

[0095] After obtaining the type of the idle power module, it needs to be compared with the type of the second power module. The second power module typically serves as an auxiliary power supply in the system or is designed specifically for specific low-power demand scenarios. If the type of the idle power module is the same as the second power module, this means that they have similar power output characteristics and applicable scenarios. At this point, the required additional power value needs to be accurately calculated based on the real-time power requirements of the third number of LED branches. Specifically, power monitoring devices distributed across each LED branch are used to obtain the power consumption of each branch in real time. These power values ​​are then aggregated to obtain the total real-time power requirement of the third number of LED branches. Next, the additional power required to meet the normal operation of these LED branches is calculated by combining the output power of other power modules in the current system (such as the first power module) with the total real-time power requirement of the third number of LED branches.

[0096] If the required supplemental power value is less than a preset threshold percentage of the adjustable power upper limit, a second percentage of the adjustable power upper limit is used as the output power of the idle power module to power the third number of LED branches; the second percentage is less than the first percentage. After calculating the required supplemental power value, it is compared with the preset threshold percentage of the adjustable power upper limit. The preset threshold percentage is a critical parameter set based on multiple factors, including system design requirements, safety standards, and energy-saving goals. If the required supplemental power value is less than the preset threshold percentage of the adjustable power upper limit, the idle power module has sufficient capacity to provide the required additional power, but does not need to use all of its available power. In this case, the second percentage of the adjustable power upper limit is used as the output power of the idle power module to power the third number of LED branches. For example, the second percentage is 40%. This second percentage is lower than the first percentage because the second power module is typically used for auxiliary power supply or for specific low-power demand scenarios. When the idle power module is of the same type, allocating power at the lower second percentage more accurately matches the potential low-power requirements of the third number of LED branches. Specifically, the first ratio and the second ratio have different percentages according to different application scenarios, and are data obtained through a large number of experiments.

[0097] In practical applications, many LED lighting systems require varying amounts of power, even at peak times or in different scenarios. Using an excessively high power allocation method can lead to overpowering and unnecessary energy waste. However, allocating power at a lower second ratio allows for precise power delivery based on actual demand, avoiding excessive energy consumption.

[0098] The step of controlling the third number of other LED branches to be electrically connected to the idle power modules includes the following sub-steps:

[0099] To properly adjust the number of connected LED branches based on the actual power consumption of idle power modules, it is necessary to obtain real-time power information for these modules. This can be achieved with the help of advanced power monitoring equipment, such as high-precision power sensors. These sensors accurately capture the power output of idle power modules at every moment during operation and transmit relevant data in real time to the system control center. The control center continuously collects and analyzes this data, providing a reliable basis for subsequent decision-making. In a large LED lighting system, there may be multiple idle power modules at the same time. Each module is equipped with a dedicated power sensor to ensure accurate real-time power information for each module.

[0100] If the real-time power is within the first preset range, the third number is adjusted based on the real-time power of the idle power module. The lower the real-time power, the larger the third number; the higher the real-time power, the smaller the third number. If the real-time power of the idle power module is within the first preset range and at a low level, this indicates that the module has a large power headroom available. From an energy utilization perspective, if this power headroom is not fully utilized, power resources will be idle and wasted. Therefore, according to the principle of "the lower the real-time power, the larger the third number," the system automatically increases the number of LED branches connected to the idle power module. This allows the idle power module to carry more load, fully tapping its power potential, thereby improving the energy efficiency of the entire power output system. Conversely, if the real-time power of the idle power module is within the first preset range and is high, it indicates that the module is approaching its power limit. In this case, further increasing the number of LED branches connected to it is likely to overload the power module, leading to a series of problems such as damage, failure, or shortening its service life. To avoid these situations, the system automatically reduces the number of LED branches connected to the idle power module, following the principle of "the higher the real-time power, the smaller the third number." By reducing the load, the power module can be ensured to operate within a safe operating range, effectively extending its service life.

[0101] If the real-time power falls within the second preset range, the third number is less than or equal to the set value. If the real-time power of the idle power module falls within the second preset range, the third number must be less than or equal to the set value to ensure system stability and safety. This set value is determined based on a combination of factors, including the performance of the idle power module, the overall system design, and safety standards. When the real-time power falls within this range, strictly limiting the number of connected LED branches can prevent damage to the power module due to excessive load and help maintain stable operation of the entire power output system.

[0102] By acquiring the real-time power of idle power modules and adopting corresponding adjustment strategies based on different power ranges, it is possible to precisely control the number of connected LED branches. This refined control method not only fully utilizes power resources and improves energy efficiency, but also ensures that the power modules operate within a safe operating range, extending their service life, thereby ensuring the efficient and stable operation of the entire power output system.

[0103] The step of searching for an idle power module in a waiting state on a power distribution branch includes the following sub-steps:

[0104] When the system issues a search command, it conducts a comprehensive search on the distribution branch to identify idle power modules in a waiting state. Once an idle power module is found, the system immediately starts a counting program to accurately record the number of idle power modules found, defining it as the idle number.

[0105] A high number of idle power modules indicates a significant number of available power modules in the system. In this situation, reducing the first reference value is crucial. The first reference value serves as a critical threshold for the system to determine whether power scheduling is necessary. Lowering its value makes it more likely that the average power value will exceed this threshold. Once the average power value exceeds the first reference value, the system triggers the power scheduling mechanism more frequently. For example, if the first reference value is originally set at 80% of the system's rated power, it may be lowered to 70% when a high number of idle power modules is detected. This way, as soon as the average power of multiple LED branches in the system reaches 70%, power adjustments are initiated for the high-load LED branches. The system quickly allocates power to these high-load branches, effectively utilizing the idle power modules. This not only avoids resource waste but also improves overall system power utilization, enabling the system to meet LED lighting needs while achieving optimal energy allocation.

[0106] If the number of idle power modules is small, it means that the idle power modules that can be deployed in the system are limited. Increasing the first reference value is a necessary strategy at this time. A higher first reference value means that the system will not easily trigger the power scheduling mechanism, and the system will only take action when the average power reaches a higher level. For example, increase the first reference value from 80% to 90%. The purpose of this is to avoid excessively frequent scheduling operations when there are insufficient idle power modules. If power scheduling is frequently performed when there are limited idle power modules, it may cause excessive load fluctuations in the existing power modules, affecting their stable operation and even causing system failures. By increasing the first reference value, it is ensured that the existing power modules can supply power to the LED branches in a relatively stable state, avoiding system instability problems caused by too frequent scheduling, and ensuring the reliability and stability of the entire LED lighting system.

[0107] The process of searching for idle power modules on the distribution branch and adjusting the first reference value based on their number is an intelligent decision-making process based on system resource conditions and operational requirements. Through this refined adjustment strategy, the system can flexibly adjust the power scheduling mechanism under different resource conditions, achieving rational resource utilization and stable system operation, providing a strong guarantee for the efficient and reliable operation of the LED lighting system.

[0108] In addition to the steps mentioned above, the scheduling method for multi-channel LED power output also includes a series of steps for analyzing and adjusting the power parameters of the distribution branches in the power bus:

[0109] To fully understand the power usage of the distribution branches within a power bus, the system first needs to obtain the power parameters of all distribution branches within the same power bus to which the LED branches belong. This process relies on high-precision power monitoring equipment, such as power sensors. These sensors, installed on each distribution branch, accurately measure the power transmitted on each branch in real time. Simultaneously, the system also monitors and calculates the total power within the same power bus. Through data acquisition and transmission technology, power data for each distribution branch and the total bus power data are aggregated and sent to the system's control center, providing basic data support for subsequent analysis and decision-making.

[0110] After obtaining the power parameters, the system calculates the power output percentage of all distribution branches based on this data. The specific calculation formula is: Power output percentage = total power transmitted on each branch / total power in the same power bus. This percentage can intuitively reflect the proportion of each distribution branch in the power output of the entire power bus. By calculating the power output percentage, the system can clearly understand the power utilization of each distribution branch, determine which branches have higher power output, and which branches have room for improvement. For example, if a power bus has five distribution branches, and the power they transmit is P1, P2, P3, P4, and P5 respectively, and the total bus power is Ptotal, then the power output percentage = (P1 + P2 + P3 + P4 + P5) / Ptotal.

[0111] The system inversely adjusts the second reference value based on the calculated power output percentage. That is, the higher the power output percentage, the smaller the second reference value; the lower the power output percentage, the larger the second reference value. This adjustment strategy is based on the overall power efficiency and stability of the system. The following describes the principles and advantages of adjustment in different situations.

[0112] When the power output percentage is low, it indicates that the overall power output of the distribution branches within the LAN still has significant room for improvement. In this case, increasing the second reference value is crucial. The second reference value serves as a critical threshold for the system to determine whether to trigger subsequent operations, such as searching for idle power modules. Increasing the second reference value means that the system will only initiate these operations when the average power level is higher. This allows the system to more fully tap the power potential of existing distribution branches under current power allocation, allowing them to shoulder a larger share of the load. For example, if the second reference value is originally set at 85% of the total bus power, it can be increased to 90% when a low power output percentage is detected. This prevents the system from rushing to search for idle power modules before the average power level reaches 90%, prioritizing increasing the power output of existing distribution branches. This prevents premature activation of backup resources, improving power resource utilization efficiency and reducing system operating costs.

[0113] If the power output percentage is high, it indicates that the distribution branch is nearing full capacity. In this case, it's necessary to reduce the second reference value. A smaller second reference value makes the system more sensitive to power fluctuations, allowing it to begin searching for idle power modules and other operations when the average power level is low. For example, lowering the second reference value from 85% to 80% will cause the system to immediately initiate a search for idle power modules when the average power level reaches 80%, promptly activating backup resources. This ensures that the power requirements of the LED branch are met, preventing overloaded existing distribution branches from impacting normal LED operation, and ensuring the stability and reliability of the entire LED lighting system.

[0114] By obtaining the power parameters of all distribution branches in the same power bus, calculating the power output percentage and adjusting the second reference value according to its anti-correlation, the system can flexibly adjust the scheduling strategy according to the actual power utilization of the distribution branches, realize the optimal allocation of power resources, and improve the overall performance and efficiency of the system.

[0115] In the multi-channel LED power output scheduling method, issuing a search command aims to achieve integrated transmission of power and communication through clever signal processing and transmission methods, thereby efficiently obtaining data information used to control the power output of the LED branches. The following are the steps and sub-steps for issuing a search command:

[0116] When the system determines that a search command is necessary, it immediately and precisely controls the signal generator based on that command. The signal generator is the starting point of the entire process, generating a specific high-frequency square wave signal based on the system's command. High-frequency square waves have unique characteristics: their high frequency and regular waveform carry rich data information, making them suitable for data transmission. The system uses precise control algorithms to ensure that the high-frequency square wave signal emitted by the signal generator strictly corresponds to the search command, guaranteeing the accuracy and reliability of subsequent data transmission.

[0117] Based on a pre-defined modulation method, the high-frequency square wave signal must be modulated with the DC power signal from the distribution branch. Modulation is a technique that transfers a low-frequency signal (such as the data carried by the high-frequency square wave signal) onto a high-frequency carrier signal (such as the DC power signal). Through modulation, the high-frequency square wave signal and the DC power signal are combined, enabling data piggyback transmission on the power transmission line. Pre-defined modulation methods can include amplitude modulation (AM), frequency modulation (FM), or phase modulation (PM), with the specific method chosen depending on the system design requirements and the actual application scenario. During this process, precise control of the modulation parameters is required to ensure that the high-frequency square wave signal can be stably and accurately modulated onto the DC power signal without affecting the normal transmission of the DC power signal. For example, amplitude modulation can be used to adjust the amplitude of the DC power signal based on the amplitude changes of the high-frequency square wave signal, thereby transferring data information to the power signal.

[0118] The modulated signal is transmitted via the DC power transmission lines of the distribution branch. Originally used to transmit electrical energy, these DC power transmission lines are now capable of transmitting not only electricity but also data through the modulation process. This method of utilizing existing power transmission lines for data transmission offers significant advantages, eliminating the need for additional communication lines and significantly reducing system construction costs and complexity. During the transmission process, factors such as line loss and interference must be considered, and appropriate measures must be taken to ensure signal quality. For example, signal amplifiers can be installed on the transmission lines to amplify the modulated signal to compensate for line loss, and filtering techniques can be used to remove interference introduced during transmission, ensuring signal clarity and accuracy.

[0119] After the signal reaches its destination, the high-frequency square wave modulated on the DC power signal needs to be extracted and purified. This process requires specialized signal extraction and purification equipment, such as filters and amplifiers. The filter separates the high-frequency square wave signal from the DC power signal based on its frequency characteristics; the amplifier amplifies the extracted high-frequency square wave signal, enhancing its strength. Simultaneously, the signal needs to be purified to remove any noise and interference, thereby improving its quality and purity. For example, a low-pass filter removes the low-frequency components of the DC power signal, retaining only the high-frequency square wave signal. A noise suppression circuit then reduces the noise level, making the signal more legible.

[0120] The extracted and purified high-frequency square wave signal needs to be demodulated to restore it to its original digital signal. Demodulation is the inverse of modulation. Using a specific demodulation algorithm, the data information embedded in the high-frequency square wave signal is recovered. The demodulated digital signal is then decoded and processed to extract the data related to the search instructions used to control the power output of the LED branches. The decoding process converts the digital signal into readable information based on pre-set encoding rules. The processing process analyzes, judges, and organizes the decoded information to extract useful data, providing a basis for subsequent power scheduling. For example, the decoding algorithm converts the digital signal into binary data. Then, according to the system's protocol rules, information such as the location and power parameters of idle power modules is extracted from this binary data. This information is used to control the power output of the LED branches.

[0121] By modulating a high-frequency square wave signal onto a DC power transmission line, the system successfully achieves integrated power and communication transmission. This innovative transmission method fully utilizes existing power infrastructure, enabling power transmission lines to function as data transmission lines without laying additional communication lines. This not only reduces system construction costs and complexity, but also improves system integration and reliability. In practical applications, this integrated transmission method can quickly and accurately transmit data related to search instructions, providing strong support for the scheduling of multi-channel LED power output, ensuring that the system can promptly adjust power distribution according to actual conditions, and improving the operating efficiency and stability of the entire LED lighting system.

[0122] This series of sub-steps in issuing search commands constitutes a complete signal processing and transmission process. Through clever modulation, transmission, demodulation and other technical means, it realizes the integrated transmission of power and communication, providing an efficient and reliable data transmission solution for the scheduling of multi-channel LED power output.

[0123] In a multi-channel LED power output dispatching system, issuing a search command is a key step in achieving intelligent power allocation. It includes a series of sub-steps that integrate communication and power transmission, providing strong support for the efficient operation of the system. The following will describe the various sub-steps of issuing a search command:

[0124] When the system determines a search command is needed based on power monitoring and analysis results, it immediately and precisely controls the signal generator based on that command. As the source of the signal, the signal generator features high-precision frequency and amplitude adjustment capabilities. Based on the search command, it emits an AC carrier signal with the specific frequency and amplitude corresponding to the command.

[0125] The frequency and amplitude of the AC carrier signal are carefully designed. A specific frequency ensures stable signal transmission along the AC power transmission lines of the distribution branch, preventing interference with other signals. The appropriate amplitude ensures sufficient signal strength to overcome line losses and noise interference, ensuring the signal reaches its target location accurately. For example, in a large shopping mall's LED lighting system, when searching for idle power modules, the signal generator might emit an AC carrier signal with a frequency of 100kHz and an amplitude of 5V.

[0126] The search command is essentially a control instruction containing specific information, but it cannot be transmitted directly over AC power transmission lines and requires some conversion. The system encodes and processes the search command, converting it into a low-frequency data signal to be modulated.

[0127] This low-frequency data signal contains all key information related to the search instruction, such as the search target, conditions, and priority. For example, the search instruction may require finding a power module with a specific power output capability and idle state. This information is encoded into binary data and then converted into a low-frequency electrical signal. The low-frequency data signal has a relatively low frequency, typically between a few hertz and tens of kilohertz, to enable efficient modulation with the AC carrier signal.

[0128] Based on the preset AC modulation method, the system modulates the low-frequency data signal with the AC carrier signal.

[0129] There are several preset AC modulation methods, including common ones like amplitude modulation (AM), frequency modulation (FM), and phase modulation (PM). Different modulation methods have different characteristics and applicable scenarios, and the system will select the most appropriate modulation method based on actual needs. Taking amplitude modulation as an example, changes in the amplitude of the low-frequency data signal cause corresponding changes in the amplitude of the AC carrier signal, thereby embedding the low-frequency data signal information into the AC carrier signal. Through this modulation process, low-frequency data signals, which would otherwise be unable to be transmitted over long distances on power lines, can now be transmitted along with the AC carrier signal on the AC power transmission lines of the distribution branch.

[0130] After modulation is complete, the modulated AC signal needs to be coupled to the AC power transmission line of the distribution branch. Coupling refers to connecting the modulated AC signal and the AC power signal so that they can be transmitted together on the same line.

[0131] This process requires specialized coupling equipment, such as a coupling transformer. The coupling transformer electrically isolates the modulated AC signal from the AC power signal while effectively injecting the modulated AC signal into the power transmission line. During the coupling process, it is crucial to ensure that the modulated AC signal does not interfere with the normal transmission of the AC power signal, while also ensuring the stability and accuracy of the signal itself. For example, by properly designing the coupling transformer's parameters, the modulated AC signal can be introduced into the power transmission line with minimal loss and interference.

[0132] After the modulated AC signal is transmitted along with the AC power signal on the distribution branch's AC power transmission line to the target location, the modulated AC signal must be extracted from the AC power signal. Because the AC power signal contains not only the modulated AC signal but also a large amount of power frequency power signals, as well as possible noise and interference signals, specialized signal extraction equipment, such as filters, is required for this extraction process.

[0133] Filters can separate the modulated AC signal from the complex AC power signal based on the signal's frequency characteristics. For example, by designing a bandpass filter to only allow signals within a specific frequency range to pass, they effectively filter out the power frequency power signal and other interfering signals, retaining only the modulated AC signal. The extracted AC signal may be contaminated to a certain degree by noise, so it also requires purification to improve its quality and purity.

[0134] The extracted and purified AC signal needs to be demodulated to restore it to the original low-frequency data signal.

[0135] The system selects the appropriate demodulation algorithm and circuit based on the modulation method used. For example, if amplitude modulation is used, the demodulation circuit will restore the original amplitude information of the low-frequency data signal based on the changes in the AC signal amplitude; if frequency modulation is used, the demodulation circuit will restore the original frequency information of the low-frequency data signal based on the changes in the AC signal frequency.

[0136] The demodulated signal is still an electrical signal containing binary data, which needs to be decoded and processed to extract data information related to the search instruction for controlling the power output of the LED branch.

[0137] The decoding process converts binary data into readable information based on pre-defined encoding rules. For example, it converts binary data into text, numbers, or other control instructions. The processing process further analyzes, judges, and organizes the decoded information to extract useful data. For example, the decoded information can determine the location and power parameters of idle power modules. This information is used to control the power output of LED branches. Based on this data, the system accurately adjusts the power distribution of each LED branch, achieving intelligent control of the LED lighting system.

[0138] Through AC modulation, search commands are converted into signals that can be transmitted over the AC power transmission lines of the distribution branch, achieving the integration of power and communications. This improves system dispatching efficiency. Traditional communication methods may require laying additional communication lines, which not only increases construction costs and difficulty but also causes signal transmission delays. However, with the integration of power and communications, search commands can be quickly and accurately transmitted within the distribution branch, allowing the system to obtain the required information in a timely manner and make rapid power dispatch decisions, improving the responsiveness and operational efficiency of the entire LED lighting system. Communication costs are also reduced. The elimination of additional communication lines reduces hardware investment and maintenance costs. Furthermore, by utilizing existing AC power transmission lines for communication, the potential of the power infrastructure is fully utilized and resource waste is avoided. This enhances intelligent control capabilities. The system accurately extracts data that controls the power output of LED branches and adjusts power allocation in real time based on actual conditions, enabling refined management of the LED lighting system. For example, the power of LED branches can be automatically adjusted based on factors such as lighting requirements, time of day, and environmental conditions in different areas, achieving energy-saving, comfortable, and efficient lighting.

[0139] This series of sub-steps of issuing search commands builds an efficient and intelligent communication and power fusion system, providing strong technical support for the scheduling of multi-channel LED power output, and promoting the development of LED lighting systems towards a more intelligent and efficient direction.

[0140] An embodiment of the present application further discloses a scheduling system for multi-channel LED power output, including a processor, wherein the processor executes the steps of any one of the above-mentioned scheduling methods for multi-channel LED power output.

[0141] The present application also discloses a distribution box, which is an ultra-thin micro intelligent distribution box. Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The device comprises a housing, which includes a detachably connected lower shell 5, an upper shell 7, and end caps 6. Two symmetrical end caps 6 protect the interfaces at both ends from dust. The housing protects the internal components, effectively preventing damage from dust, moisture, and external forces. The housing houses a circuit board 1, power driver components, an expansion compartment 8, a power module, a communication module, and a processor.

[0142] Circuit board 1 includes a basic function module and an onboard remote control module. It also features power supply ports with different voltages and a communication interface for connecting expansion function boards. This integrated design greatly facilitates functional management and coordination across the entire distribution box. The basic function module covers a series of basic yet crucial functions, such as data processing and logical operations, and serves as the foundation for the distribution box's various control operations. Circuit board 1 also incorporates an onboard remote control module and antenna 4. This high-performance antenna 4 enables remote control of the distribution box, with a range of over 100 meters. This allows users to easily control the distribution box even from remote locations, greatly enhancing ease of use. Furthermore, circuit board 1 provides a communication interface and power supply ports with different voltages. These interfaces enable seamless integration with various expansion function boards, enabling easy control via multi-function cards and third-party control software, as well as connection to PLC function boards for more complex industrial automation. The power supply ports with different voltages meet the diverse voltage requirements of expansion function boards, providing strong support for functional expansion and enabling flexible customization of the distribution box's functionality based on specific application scenarios.

[0143] The power drive element uses a magnetic latching relay 2, which has unique advantages. It can effectively meet the design requirements of the thin distribution box and makes a significant contribution to the realization of the distribution box's lightweight and thinness. However, the magnetic latching relay 2 is a holding type action element and is not self-restoring, which poses certain safety risks. To ensure safe use, a back-drive circuit is specially integrated on the circuit board 1. In the event of a power outage, the back-drive circuit can quickly take effect and automatically disconnect the magnetic latch, effectively avoiding safety accidents caused by accidental power-on, and effectively ensuring the safety of personnel and equipment.

[0144] The expansion compartment 8 is used to connect the expansion function board. Users can easily connect various expansion function boards according to their actual needs. In terms of design, the expansion compartment 8 fully considers safety and convenience. When the end cover 6 (expansion compartment 8) is opened, the internal control components will not be exposed to the outside, effectively avoiding safety problems caused by accidental touch and the like. Users can install a multi-function card in the expansion compartment 8 and use third-party control software to achieve more flexible and diverse control methods; they can also install a PLC function module and achieve advanced functions such as remote control and remote wireless control by docking with the upper computer software to meet the needs of intelligent control of distribution boxes in different industries and different scenarios. It can support central control: central control can be achieved without expanding any functional modules. It can support AI voice control (external): AI voice dialogue control can be achieved after expanding the voice control module.

[0145] The input and output line structure is installed below the shell, and the input and output line method is bottom-in and bottom-out; because of the need for dust prevention, the input line needs to be placed at the bottom. Compared with the traditional top-in and bottom-out method, it has significant advantages. In actual use scenarios, especially in some dusty environments, the bottom-in and bottom-out method can effectively reduce the probability of dust entering the interior of the components. Once dust enters the interior of the distribution box and accumulates on the components, it is very easy to cause faults such as short circuits when power is turned on, causing the components to burn. This improved input and output line method greatly reduces the risk of power-on burns caused by dust, significantly improves the dustproof performance of the distribution box, extends the service life of the distribution box, and ensures its operational stability. Among them, the wiring structure of the input and output lines adopts a copper sheet 3 structure, and the copper sheet 3 is fixed to the lower shell 5 using a combination of screws and patterned nuts, and is electrically connected to the circuit board 1.

[0146] The power supply module includes a first power module, a second power module, and a distribution branch. The first power module and the second power module are respectively used to power multiple LED branches. The distribution branch is used to connect to idle power modules. When the system detects an increase in power demand that cannot be met by the existing power modules, the distribution branch can quickly connect to the idle power modules, enabling flexible power allocation and ensuring the stable operation of the entire LED lighting system.

[0147] In this embodiment, both 10kW and 20kW distribution boxes can implement single-circuit start / stop control; they offer manual start / stop control and also support timed control. 10kW is controlled in three circuits, while 20kW is controlled in six circuits. This means the first power module can power three LED branches, while the second power module can power another three. Idle power modules are those in other distribution boxes within the same busbar power supply.

[0148] The communication module, controlled by a processor, utilizes advanced signal processing technology. By cleverly superimposing the corresponding search command with the power signal from the distribution branch, it achieves efficient transmission of the search command. This approach not only fully utilizes existing distribution branches, avoiding the increased cost and wiring complexity associated with laying additional communication lines, but also accurately obtains the key information needed to control the power output of the LED branch while transmitting the search command, providing strong support for precise power scheduling.

[0149] The processor executes the steps of the above-mentioned method for scheduling the power output of multiple LEDs and is used to issue a search instruction.

[0150] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
