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 dedicated to LED lighting have emerged. Compared with LED distribution boxes, traditional distribution boxes are designed based on industrial frequency alternating current and cannot meet the requirements of low-voltage direct current power supply, precise dimming, and multi-loop independent control of LEDs. Early LED distribution boxes were mainly applied to lighting projects and urban construction. With the development of Internet of Things technology, they have gradually evolved towards the direction of intelligence and modularization.

[0003] The LED distribution box realizes the expansion of scenario-based applications by integrating multiple functional modules. The voice module can support voice control instructions. For example, it can achieve quick response through voice interactions such as "turn on emergency lighting", which is especially suitable for environments such as computer rooms and unmanned base stations. Sensor modules such as light, temperature, and humidity sensors can real-time monitor environmental parameters and automatically adjust the LED brightness in combination with the dimming module. For example, the power can be reduced to save energy when the light is sufficient. The flexible combination of these modules upgrades the LED distribution box from a single power distribution device to an intelligent control center, which is widely used in fields such as building intelligence and landscape lighting.

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

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

[0006] In the first aspect, the present application provides a scheduling method for multi-channel LED power output, adopting the following technical solution: A scheduling method for multi-channel LED power output includes the following steps: Based on multiple LED branches powered by a first power module, obtain the branch power corresponding to the LED branches; Calculate the power average value of the multiple branch powers; If the power average value is greater than a preset first reference value, calculate the number of the LED branches whose branch power is less than the power average value as the first number; calculate the number of the other LED branches as the second number; If the first quantity is greater than the second quantity and the second power module is not started, start the second power module, control the second power module to supply power to the other LED branches, and cut the other LED branches out of the first power module; If the first quantity is greater than the second quantity and the second power module has been started, activate the connected distribution branch in standby mode; the distribution branch is used to connect the idle power module; If the power average value is greater than a preset second reference value, issue a search instruction; Based on the search instruction, search for an idle power module in a waiting state on the distribution branch; wherein, the second reference value is greater than the first reference value; If the idle power module is found, switch the distribution branch from standby mode to power mode, switch the idle power module from the waiting state to the power supply state; control the other LED branches with the third quantity to be electrically connected to the idle power module, and cut the LED branches electrically connected to the idle power module out of the second power module; If the idle power module is not found, issue a full load prompt.

[0007] By adopting the above technical solution, the power of each LED branch is obtained in real time and the average value is calculated, and different levels of scheduling strategies are triggered based on this: when the power average value exceeds the first reference value and the number of low-load branches is more than that of high-load branches, if the second power module is not enabled, start it to take over the high-load branches to avoid overload of the first power module; if the second power module is already working, activate the standby distribution branch. When the power average value breaks through the higher second reference value, further search for idle power modules, activate them and reallocate the high-load branches to realize flexible transfer of power among multiple modules. This progressive scheduling mechanism greatly improves the power utilization rate of the system, 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 standby module and the distribution branch, the fault tolerance of the system is enhanced, and it can be quickly switched during a fault to ensure power supply continuity; and this method relies on the existing circuit architecture, does not require a large amount of modification, and reduces the deployment cost.

[0008] Optionally, in the step of switching the idle power module from the waiting state to the power supply state, the following sub-steps are included: Obtain the type, real-time output power and adjustable power upper limit of the idle power module; When the type of the idle power module is the same as that of the first power module, calculate the required supplementary power value according to the real-time power demand of the LED branches with the third quantity; The required supplementary power value is less than a preset proportional threshold of the adjustable power upper limit, and a first proportional power of the adjustable power upper limit is used as the output power of the idle power module to supply power to the third number of LED branches.

[0009] By adopting the above technical solution, when the idle power module is of the same type as the first power module, it usually means that they have similar high-power output capabilities and stability. In this case, allocating power at a relatively high first ratio can quickly and efficiently meet the possible high-power demands of the third number of LED branches.

[0010] Optionally, in the step of switching the idle power module from the waiting state to the power supply state, the following sub-steps are included: Obtain the type, real-time output power, and adjustable power upper limit of the idle power module; When the type of the idle power module is the same as the type of the second power module, calculate the required supplementary power value according to the real-time power demand of the third number of LED branches; The required supplementary power value is less than a preset proportional threshold of the adjustable power upper limit, and a second proportional power of the adjustable power upper limit is used as the output power of the idle power module to supply power to the third number of LED branches; wherein, the second ratio is less than the first ratio.

[0011] By adopting the above technical solution, the second power module is usually a module for auxiliary power supply or for specific low-power demand scenarios. When the idle power module is of the same type as it, allocating power at a lower second ratio can accurately match the possible low-power demands of the third number of LED branches. This can avoid over-power supply, reduce unnecessary energy consumption, and thus reduce the operating cost of the entire system.

[0012] Optionally, in the step of controlling the third number of other LED branches to be electrically connected to the idle power module, the following sub-steps are included: Obtain the real-time power of the idle power module in real time; If the real-time power is within a first preset range, then adjust the third number according to 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 is within a second preset range, the third number is less than or equal to a set value.

[0013] By adopting the above technical solution, when the real-time power of the idle power module is within the first preset range and 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 quantity, increasing the number of LED branches connected to it can enable the idle power module to carry more loads, avoid the idle and waste of power resources, fully exploit its power potential, and improve the energy utilization efficiency of the entire power output system. If the real-time power is relatively high, it indicates that the idle power module is approaching its power limit. According to the principle that the higher the real-time power, the smaller the third quantity, reducing the number of LED branches connected to it can prevent the power module from being damaged or malfunctioning due to overload, ensure that the power module operates within a safe working range, and extend its service life.

[0014] Optionally, in the step of searching for idle power modules in the power distribution branch that are in a waiting state, the following sub-steps are included: If the idle power module is found, count the number of the found idle power modules as the idle quantity; Inversely adjust the first reference value according to the idle quantity. The larger the idle quantity, the smaller the first reference value; the smaller the idle quantity, the larger the first reference value.

[0015] By adopting the above technical solution, when the idle quantity is large, it means that there are more idle power modules available for allocation in the system. At this time, when the first reference value is adjusted to be smaller, the system will trigger the power scheduling mechanism more frequently. Because a lower first reference value makes it easier for the power average value to exceed the threshold, which in turn prompts the system to start adjusting the power of high-load LED branches earlier, and allocate these high-load branches to the idle power modules for power supply. This can make full use of the idle power modules, avoid resource waste, and improve the power utilization rate of the entire system. If the idle quantity is small, it indicates that the number of idle power modules available for allocation in the system is limited. At this time, increasing the first reference value, the system will not easily trigger power scheduling, and will only take action when the power average value reaches a relatively high level. This avoids over-frequent scheduling in the case of insufficient idle power modules, ensures that the existing power modules can stably supply power to the LED branches, and avoids system instability caused by overly frequent scheduling.

[0016] Optionally, the method further includes the following steps: Obtain the power parameters of all power distribution branches in the same power supply 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 supply bus; Calculate the power output percentage of all power distribution branches according to the power parameters = the sum of the power transmitted on each branch / the total power in the same power supply bus; Adjust the second reference value in inverse correlation with the power output percentage; the larger the power output percentage, the smaller the second reference value; the smaller the power output percentage, the larger the second reference value.

[0017] By adopting the above technical solution, when the power output percentage is small, it indicates that there is still a large room for improvement in the overall power output of the distribution branches within the local area network. At this time, increasing the second reference value means that the system will trigger subsequent operations such as searching for idle power modules at a higher power average level. This enables the system to more fully exploit the power potential of the existing distribution branches under the current power distribution situation, allowing them to carry more loads and avoiding premature activation of backup resources, thereby improving the utilization efficiency of power resources. If the power output percentage is large, it means that the distribution branches are operating close to full load. At this time, by reducing the second reference value, the system will be more sensitive to power changes and start searching for idle power modules etc. when the power average value is relatively low. This can enable the timely activation of backup resources to ensure that the power requirements of the LED branches are met and avoid affecting the normal operation of the LEDs due to overload of the existing distribution branches.

[0018] Optionally, the step of issuing the search instruction includes the following sub-steps: Based on the search instruction, control a signal generator, and the signal generator issues a high-frequency square wave signal corresponding to the search instruction; Based on a preset modulation method, modulate the high-frequency square wave signal with the DC power signal of the distribution branch; Transmit the modulated signal through the DC power transmission line of the distribution branch; Extract and purify the high-frequency square wave signal modulated on the DC power signal, and demodulate the high-frequency square wave signal; Decode and process the demodulated digital signal, and extract the data information related to the search instruction for controlling the power output of the LED branch.

[0019] By adopting the above technical solution, modulating the high-frequency square wave signal onto the DC power transmission line enables data information to be carried while power is being transmitted, thereby realizing the integrated transmission of power and communication without laying additional communication lines.

[0020] Optionally, the step of issuing the search instruction includes the following sub-steps: Based on the search instruction, control a signal generator, and the signal generator issues an AC carrier signal with a specific frequency and amplitude corresponding to the search instruction; Convert the search instruction into a low-frequency data signal to be modulated; Based on a preset AC modulation method, modulate the low-frequency data signal with the AC carrier signal; Couple the modulated AC signal to the AC power transmission line of the power distribution branch; Extract the modulated AC signal from the AC power signal; Demodulate the extracted and purified AC signal to restore the original low-frequency data signal; Decode and process the demodulated signal to extract the data information related to the search instruction for controlling the power output of the LED branch.

[0021] By adopting the above technical solution, the search instruction is converted into a signal that can be transmitted on the AC power transmission line of the power distribution branch through AC modulation, realizing the integration of power and communication, accurately extracting the data information for controlling the power output of the LED branch, improving the system scheduling efficiency, reducing the communication cost and enhancing the intelligent control level.

[0022] In a second aspect, the present application provides a scheduling system for multi-channel LED power output, adopting the following technical solution: A scheduling system for multi-channel LED power output, including a processor, and the processor executes the steps of the scheduling method for multi-channel LED power output described in any one of the above.

[0023] In a third aspect, the present application provides a distribution box, adopting the following technical solution: A distribution box includes a housing, and a circuit board, a power driving element, an expansion bin, a power supply module, a communication module and a processor are arranged in the housing; The circuit board includes a basic function module and an on-board remote control function module; an antenna, different voltage power supply ports, and a communication interface for connecting an expansion function board are arranged on the circuit board; The power driving element includes a magnetic latching relay, and the magnetic latching relay is electrically connected to the circuit board; an anti-drive circuit is arranged on the circuit board; The expansion bin is used for connecting an expansion function board; The power supply module includes a first power module, a second power module and a power distribution branch. 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 an idle power module; The communication module is controlled by the processor, and realizes the transmission of the search instruction and obtains the control of the power output of the LED branch by superimposing the corresponding search instruction on the power signal of the power distribution branch; The processor executes the steps of the above-mentioned scheduling method for multi-channel LED power output, and is used to issue a search instruction.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: improving the power utilization rate of the system, reducing the risk of local overload, and enhancing the load capacity of the LED distribution box; enhancing the fault tolerance of the system and ensuring power supply continuity; relying on the existing circuit architecture to reduce deployment costs; achieving precise power distribution and reducing energy consumption; through integrated power and communication transmission, improving the system scheduling efficiency, reducing communication costs, and enhancing the intelligent control level.

[0032] The following details the embodiments of the present application, and the examples of the embodiments are shown in the drawings.

[0033] In the description of this specification, the description referring to the terms "certain embodiments", "one embodiment", "some embodiments", "schematic embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiments or examples are included in at least one embodiment or example of the present application. In this specification, the schematic descriptions of the above terms do not necessarily refer to the same embodiments or examples. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0034] The embodiments of the present application disclose a scheduling method for multi-channel LED power output. Referring to Figure 1 and Figure 2 , the method includes the following steps: Based on multiple LED branches powered by the first power module, obtain the branch power corresponding to the LED branches. By setting power monitoring elements, such as power sensors, in the circuit, the power data of each LED branch is collected in real time, and this data will be used as the basic information for subsequent power scheduling.

[0035] Calculate the power average value of multiple branch powers; the average value can reflect the overall power consumption level of the current multiple LED branches and is an important reference index for judging the power state of the system.

[0036] If the power average value is greater than the preset first reference value, then calculate the number of LED branches with branch power less than the power average value as the first quantity; calculate the number of other LED branches as the second quantity. The preset first reference value is a power threshold set according to the design requirements and actual operation experience of the system, and is used to judge whether the system is in a relatively high power load state. When the power average value exceeds this threshold, further analyze the power situation of each LED branch, count the number of branches with power less than the average value as the first quantity, and the number of branches with power greater than or equal to the average value as the second quantity.

[0037] If the first quantity is greater than the second quantity and the second power module is not started, then start the second power module, control the second power module to supply power to other LED branches, and cut other LED branches out of the first power module. When the number of low-load branches is more than the number of high-load branches and the second power module is in the unstarted state, it indicates that the first power module may face an overload risk. At this time, start the second power module, switch the high-load LED branches to be powered by the second power module, share the load of the first power module, avoid its damage due to overload, and ensure the stable operation of the system.

[0038] If the first quantity is greater than the second quantity and the second power module has been started, then activate the connected distribution branch in the standby mode; the distribution branch is used to connect the idle power module. When the second power module is already in operation, but there are still many low-load branches and few high-load branches in the system, it means that the existing two power modules may not be sufficient to meet the power demand of the system. At this time, activate the standby distribution branch to prepare for connecting the idle power module, so as to further increase the power supply capacity of the system. The standby distribution branch is in the standby mode under normal circumstances and does not participate in power transmission. When activated, it can quickly connect to the idle power module to achieve power supplement.

[0039] If the average power is greater than a preset second reference value, a search instruction is issued. Based on the search instruction, idle power modules in a waiting state are searched for on the distribution branch; wherein, the second reference value is greater than the first reference value. The second reference value being greater than the first reference value is a higher power threshold. When the average power breaks through the second reference value, it indicates that the power demand of the system further increases, and more proactive measures need to be taken to meet the power demand. At this time, a search instruction is issued to start searching for idle power modules on the distribution branch to find additional power support.

[0040] If an idle power module is found, the 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; control other LED branches with a third quantity to be electrically connected to the idle power module, and cut out the second power module from the LED branches electrically connected to the idle power module. Search for idle power modules on the distribution branch. If found successfully, activate the standby distribution branch to the normal working power mode, and at the same time start the idle power module to enter the power supply state. Then, according to the actual situation of the system, connect a certain number (the third quantity) of high-load LED branches to the newly activated idle power module, and cut out these branches from the second power module to realize the redistribution of power among multiple power modules, further optimizing the power distribution of the system and meeting the high-load demand.

[0041] If no idle power module is found, a full-load prompt is issued. When no idle power module is found after the search, it means that there are no additional power resources available for the system to call at present. At this time, a full-load prompt is issued to remind the operator that the system has reached the power limit and corresponding measures need to be taken, such as reducing the load or increasing power equipment, to avoid system failures due to overload.

[0042] Obtain the power of each LED branch in real time and calculate the average value, and trigger different levels of scheduling strategies based on this. This progressive scheduling mechanism greatly improves the system power utilization rate, 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 idle power module and the distribution branch, the system fault tolerance is enhanced, and the power supply continuity can be quickly switched to ensure in case of a failure; moreover, this method relies on the existing circuit architecture, does not require a large number of modifications, and reduces the deployment cost.

[0043] Refer to Figure 2 and Figure 3 , in the step of switching the idle power module from the waiting state to the power supply state, the following sub-steps are included: It is necessary to comprehensively obtain relevant information about the idle power module, including its type, real-time output power, and the upper limit of adjustable power. The type of the idle power module is an important feature. Different types of power modules may have significant differences in power output capacity, stability, applicable scenarios, etc. The real-time output power reflects the actual power output by the module currently, while the upper limit of adjustable power defines the maximum additional power that the module can provide under the premise of safe and stable operation. Through advanced sensor technology and data acquisition systems, these key parameters can be accurately obtained.

[0044] When the type of the idle power module is the same as that of the first power module, it indicates that these two power modules have high similarity in performance and characteristics. It means they have similar high power output capabilities and stability. At this time, it is necessary to accurately calculate the required supplementary power value according to the real-time power demand of the third number of LED branches. That is, by monitoring the real-time power of the third number of LED branches, the current power consumption of each branch is obtained, and then these power values are summarized to obtain the total real-time power demand. Then, combined with the current output power of the first power module and the second power module, the additional power value required to ensure the normal operation of the third number of LED branches is calculated. For example, assume that the third number is 5 LED branches, and their real-time power demands are P1, P2, P3, P4, and P5 respectively. Then the total real-time power demand Ptotal demand = P1 + P2 + P3 + P4 + P5. Then, according to the output power of the first power module and the second power module, the required supplementary power value Psupplement = Ptotal demand - (the current output power of the first power module + the current output power of the second power module) is calculated.

[0045] After calculating the required supplementary power value, it is necessary to compare it with the preset proportional threshold of the adjustable power upper limit. The preset proportional threshold is an important parameter set according to the design requirements and safety considerations of the system, which ensures that the safe operating range of the idle power module will not be exceeded when it is used. If the required supplementary power value is less than the preset proportional threshold of the adjustable power upper limit, it means that the idle power module has sufficient ability 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 supply power to the third number of LED branches. For example, select the first proportional power as 80% of the power. Since the idle power module has the same type as the first power module and has similar high power output capabilities and stability, allocating power at a relatively high first proportion can quickly and efficiently meet the possible high power demands of the third number of LED branches.

[0046] Ensures that when the idle power module is put into use, reasonable power distribution can be carried out according to the actual situation, giving full play to the role of the idle power module and ensuring the stable and efficient operation of the entire LED lighting system.

[0047] In the step of switching the idle power module from the waiting state to the power supply state, the following sub-steps are included: After the system determines that the idle power module needs to be put into use, relevant information of the idle power module is obtained, including the type of the idle power module, the real-time output power, and the upper limit of adjustable power. The type of the module determines key factors such as its power characteristics, applicable scenarios, and compatibility; the real-time output power reflects the current working state of the module; while the upper limit of adjustable power clarifies the maximum additional power that the module can provide on the premise of safe and stable operation. Through advanced sensor technology and intelligent monitoring systems, this information is collected in real time and accurately.

[0048] After obtaining the type of the idle power module, it is necessary to compare it with the type of the second power module. The second power module usually plays an auxiliary power supply role in the system or is a module designed specifically for specific low-power demand scenarios. If the type of the idle power module is the same as the type of the second power module, it means that they have similarities in power output characteristics and applicable scenarios. At this time, it is necessary to accurately calculate the power value to be supplemented according to the real-time power demand of the third number of LED branches. Specifically, through the power monitoring devices distributed on each LED branch, the power consumption of each branch is obtained in real time, and then these power values are summarized to obtain the total real-time power demand of the third number of LED branches. Then, combined with the output power of other power modules (such as the first power module) in the current system and the total real-time power demand of the third number of LED branches, the additional power value required to ensure the normal operation of these LED branches is calculated.

[0049] When the required supplementary power value is less than the preset ratio threshold of the adjustable power upper limit, the second ratio power of the adjustable power upper limit is used as the output power of the idle power module to supply power to the third number of LED branches; wherein, the second ratio is less than the first ratio. After calculating the required supplementary power value, it is necessary to compare it with the preset ratio threshold of the adjustable power upper limit. The preset ratio threshold is an important parameter comprehensively set based on various factors such as the design requirements, safety standards, and energy-saving goals of the system. If the required supplementary power value is less than the preset ratio threshold of the adjustable power upper limit, it means that the idle power module has sufficient ability to provide the required additional power, but it is not necessary to put all its adjustable power into use. At this time, the second ratio power of the adjustable power upper limit is used as the output power of the idle power module to supply power to the third number of LED branches. For example, the second ratio is 40%. Here, the second ratio is less than the first ratio because the second power module is usually used for auxiliary power supply or for specific low-power demand scenarios. When the idle power module is of the same type as it, allocating power at a lower second ratio can more precisely match the possible low-power demands of the third number of LED branches. Specifically, the first ratio and the second ratio vary depending on the application scenario, and the percentage selection is data obtained through a large number of experiments.

[0050] In practical applications, in many LED lighting systems, their power requirements are not always at peak levels during different time periods or scenarios. If a too-high power allocation method is adopted, it will lead to over-power supply and cause unnecessary energy waste. By allocating power at a lower second ratio, it is possible to supply power precisely according to actual needs and avoid excessive energy consumption.

[0051] In the step of controlling the connection of the third number of other LED branches to the idle power module, the following sub-steps are included: In order to be able to reasonably adjust the number of connected LED branches according to the actual power situation of the idle power module, it is necessary to obtain the real-time power of the idle power module in real time. This can be achieved by means of advanced power monitoring devices, such as high-precision power sensors. These sensors can accurately capture the power output situation of the idle power module at every moment during operation and transmit the relevant data to the control center of the system in real time. The control center will continuously collect and analyze these data to provide a reliable basis for subsequent decisions. In a large LED lighting system, there may be multiple idle power modules at the same time, and each module is equipped with a dedicated power sensor to ensure that the real-time power of each module can be accurately obtained.

[0052] When the real-time power is within the first preset range, the third quantity is adjusted according to the real-time power of the idle power module. The lower the real-time power, the larger the third quantity; the higher the real-time power, the smaller the third quantity. If the real-time power of the idle power module is within the first preset range and at a relatively low level, it means that the module has a relatively large power margin available for use. From the perspective of energy utilization, if this part of the power margin is not fully utilized at this time, it will result in the idling and waste of power resources. Therefore, according to the rule of "the lower the real-time power, the larger the third quantity", the system will automatically increase the number of LED branches connected to the idle power module. In this way, the idle power module can carry more loads, fully exploit its power potential, and thus improve the energy utilization efficiency of the entire power output system. On the contrary, if the real-time power of the idle power module is within the first preset range and relatively high, it indicates that the module is approaching its power limit. In this case, if the number of LED branches connected to it is continuously increased, it is very likely to cause the power module to be overloaded, which may in turn lead to a series of problems, such as damage to the power module, malfunctions, or affecting its service life. To avoid these situations, the system will follow the principle of "the higher the real-time power, the smaller the third quantity" and automatically reduce the number of LED branches connected to the idle power module. By reducing the load, it can ensure that the power module operates within a safe working range and effectively extend its service life.

[0053] When the real-time power is within the second preset range, the third quantity is less than or equal to the set value. If the real-time power of the idle power module is within the second preset range, in order to ensure the stability and safety of the system, the third quantity needs to be less than or equal to the set value. This set value is determined comprehensively based on various factors such as the performance of the idle power module, the overall design of the system, and safety standards. When the real-time power is within this range, strictly restricting the number of connected LED branches can avoid damaging the power module due to excessive load and also help maintain the stable operation of the entire power output system.

[0054] By obtaining the real-time power of the idle power module in real time and adopting corresponding adjustment strategies according to different power ranges, precise control of the number of connected LED branches can be achieved. This refined control method can not only make full use of power resources and improve energy utilization efficiency, but also ensure that the power module operates within a safe working range, extend its service life, and thus guarantee the efficient and stable operation of the entire power output system.

[0055] In the step of searching for idle power modules in the waiting state on the distribution branch, the following sub-steps are included: After the system issues a search command, it will conduct a comprehensive search on the distribution branch to find the idle power modules in the waiting state. Once an idle power module is found, the system will immediately start a statistical program to accurately record the number of idle power modules found, which is defined as the idle quantity.

[0056] When the idle quantity is large, it means there are many idle power modules in the system available for allocation. In this case, it is of great significance to reduce the first reference value. As a key threshold for the system to judge whether power scheduling is needed, the reduction of the value of the first reference value makes it easier for the power average value to exceed this threshold. Once the power average value exceeds the first reference value, the system will trigger the power scheduling mechanism more frequently. For example, in a system where the first reference value was originally set at 80% of the system rated power, when a large number of idle power modules are detected, the first reference value is lowered to 70%. In this way, as long as the power average value of multiple LED branches in the system reaches 70%, the power adjustment operation for the high-load LED branches will be started. The system will quickly allocate these high-load branches to be powered by the idle power modules, thus making full use of the idle power module resources. This not only avoids waste of resources but also improves the power utilization rate of the entire system, enabling the system to achieve optimal energy allocation while meeting the LED lighting requirements.

[0057] If the idle quantity is small, it indicates that there are limited idle power modules available for allocation in the system. At this time, increasing the first reference value is a necessary strategy. 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 power average value reaches a higher level. For example, the first reference value is increased from 80% to 90%. The purpose of this is to avoid overly frequent scheduling operations when the idle power modules are insufficient. If power scheduling is carried out frequently when the idle power modules are limited, it may cause excessive load fluctuations of the existing power modules, affecting their stable operation and even possibly 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 overly frequent scheduling and ensuring the reliability and stability of the entire LED lighting system.

[0058] The process of searching for idle power modules on the distribution branch and adjusting the first reference value according to their quantity is an intelligent decision-making process based on the system resource status and operation requirements. Through this refined adjustment strategy, the system can flexibly adjust the power scheduling mechanism under different resource conditions, realize the rational use of resources and the stable operation of the system, providing a strong guarantee for the efficient and reliable operation of the LED lighting system.

[0059] In the scheduling method for multi-channel LED power output, in addition to the steps mentioned above, it also includes a series of analysis and adjustment steps for the power parameters of the distribution branches in the power bus: To comprehensively understand the power usage of the distribution branches in the power bus, the system first needs to obtain the power parameters of all distribution branches in the same power bus to which the LED branch belongs. This process relies on high-precision power monitoring devices, such as power sensors. These sensors are installed on each distribution branch and can measure the power transmitted on each branch in real time and accurately. At the same time, the system also monitors and statistics the total power in the same power bus. Through data acquisition and transmission technology, the power data of each distribution branch and the total power data of the bus are aggregated to the control center of the system, providing basic data support for subsequent analysis and decision-making.

[0060] After obtaining the power parameters, the system will calculate the power output percentage of all distribution branches based on these data. The specific calculation formula is: Power output percentage = sum of the 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, and judge which branches have a higher power output and which branches still have room for improvement. For example, if there are 5 distribution branches in a power bus, and the power they transmit are P1, P2, P3, P4, P5 respectively, and the total power of the bus is P total, then the power output percentage = (P1 + P2 + P3 + P4 + P5) / P total.

[0061] The system will perform an inverse correlation adjustment on the second reference value according to the calculated power output percentage. That is, the larger the power output percentage, the smaller the second reference value; the smaller the power output percentage, the larger the second reference value. This adjustment strategy is based on the overall power utilization efficiency and stability of the system. The principles and advantages of the adjustment in different situations are elaborated below.

[0062] When the power output percentage is small, it indicates that there is still a large room for improvement in the overall power output of the power distribution branches within the local area network. At this time, increasing the second reference value is of great significance. The second reference value is a key 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 start these operations at a higher average power level. The advantage of this is that under the current power distribution situation, the system can more fully explore the power potential of the existing power distribution branches and let them carry more loads. For example, when the second reference value was originally set at 85% of the total bus power, when the detected power output percentage is small, the second reference value is increased to 90%. This makes it so that before the average power reaches 90%, the system will not be eager to search for idle power modules but will first let the existing power distribution branches increase their power output. In this way, premature activation of backup resources is avoided, thereby improving the utilization efficiency of power resources and reducing the operating cost of the system.

[0063] If the power output percentage is large, it means that the power distribution branches are operating near full load. In this case, it is necessary to reduce the second reference value. A smaller second reference value makes the system more sensitive to power changes and start operations such as searching for idle power modules when the average power is low. For example, the second reference value is reduced from 85% to 80%. In this way, when the average power reaches 80%, the system will immediately start the program to search for idle power modules and enable backup resources in a timely manner. This can ensure that the power requirements of the LED branches are met, avoid affecting the normal operation of the LEDs due to overloading of the existing power distribution branches, and guarantee the stability and reliability of the entire LED lighting system.

[0064] By obtaining the power parameters of all power distribution branches in the same power bus, calculating the power output percentage, and adjusting the second reference value in an inverse correlation according to it, the system can flexibly adjust the scheduling strategy based on the actual power utilization situation of the power distribution branches, achieve optimal allocation of power resources, and improve the overall performance and efficiency of the system.

[0065] In the scheduling method for multi-channel LED power output, the purpose of sending a search instruction is to achieve integrated transmission of power and communication through ingenious signal processing and transmission methods, so as to efficiently obtain the data information used to control the power output of the LED branches. The following are the steps and sub-steps of sending a search instruction: When the system determines that a search instruction needs to be issued, it will immediately perform precise control on the signal generator based on this search instruction. The signal generator is the starting point of the entire process. It can generate specific high-frequency square wave signals according to the system's instructions. The high-frequency square wave signal has unique characteristics. Its frequency is relatively high and the waveform is regular, which can carry rich data information and is 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 instruction, guaranteeing the accuracy and reliability of subsequent data transmission.

[0066] It is necessary to modulate the high-frequency square wave signal with the DC power signal of the distribution branch based on a preset modulation method. Modulation is a technology that loads a low-frequency signal (such as the data information 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 can be combined with the DC power signal to achieve the transmission of data on the power transmission line. The preset modulation method can be of various types, such as amplitude modulation (AM), frequency modulation (FM), or phase modulation (PM), etc. The specific choice of modulation method depends on the system's design requirements and actual application scenarios. In this process, it is necessary to precisely control the modulation parameters 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, when using the amplitude modulation method, the amplitude of the DC power signal is adjusted according to the amplitude change of the high-frequency square wave signal, thereby loading the data information into the power signal.

[0067] The modulated signal is transmitted through the DC power transmission line of the distribution branch. The DC power transmission line of the distribution branch was originally a channel for transmitting electrical energy. Through the above modulation process, it can now not only transmit power but also carry data information simultaneously. This way of using the existing power transmission line for data transmission has significant advantages. There is no need to lay additional communication lines, greatly reducing the construction cost and complexity of the system. During the transmission process, factors such as line loss and interference need to be considered, and corresponding measures should be taken to ensure the signal quality. For example, signal amplifiers are installed on the transmission line to amplify the modulated signal to compensate for line loss; filtering technology is used to remove the interference signals introduced during the transmission process to ensure the clarity and accuracy of the signal.

[0068] After the signal is transmitted to the destination, it is necessary to extract and purify the high-frequency square wave signal modulated on the DC power signal. This process requires the use of specialized signal extraction and purification equipment, such as filters, amplifiers, etc. The filter can separate the high-frequency square wave signal from the DC power signal according to the frequency characteristics of the signal; the amplifier amplifies the extracted high-frequency square wave signal to enhance the signal strength. At the same time, it is also necessary to purify the signal to remove the possible noise and interference in the signal, and improve the quality and purity of the signal. For example, a low-pass filter is used to remove the low-frequency components in the DC power signal and only retain the high-frequency square wave signal; then, through a noise suppression circuit, the noise level in the signal is reduced, making the signal clearer and more distinguishable.

[0069] The extracted and purified high-frequency square wave signal needs to be demodulated to restore it to the original digital signal. Demodulation is the inverse process of modulation. Through specific demodulation algorithms, the data information loaded on the high-frequency square wave signal is restored. Then, the demodulated digital signal is decoded and processed to extract the data information related to the search instruction for controlling the power output of the LED branch. The decoding process converts the digital signal into readable information according to the pre-set coding 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 digital signal is converted into binary data through a decoding algorithm, and then according to the protocol rules of the system, information such as the position and power parameters of the idle power module are extracted from the binary data, and these information will be used to control the power output of the LED branch.

[0070] By modulating the high-frequency square wave signal onto the DC power transmission line, the integrated transmission of power and communication is successfully achieved. This innovative transmission method makes full use of the existing power infrastructure. Without laying additional communication lines, the power transmission line is also equipped with the function of data transmission. This not only reduces the construction cost and complexity of the system, but also improves the integration and reliability of the system. In practical applications, this integrated transmission method can quickly and accurately transmit the data information related to the search instruction, providing strong support for the scheduling of multi-channel LED power output, ensuring that the system can adjust the power distribution in a timely manner according to the actual situation, and improving the operation efficiency and stability of the entire LED lighting system.

[0071] This series of sub-steps of issuing the search instruction constitutes a complete signal processing and transmission process. Through ingenious modulation, transmission, demodulation and other technical means, the integrated transmission of power and communication is achieved, providing an efficient and reliable data transmission solution for the scheduling of multi-channel LED power output.

[0072] In a scheduling system for multi-channel LED power output, issuing a search instruction is a crucial step in achieving intelligent power allocation. A series of sub-steps it contains integrate communication and power transmission, providing strong support for the efficient operation of the system. The following will describe each sub-step of issuing a search instruction: When the system determines, based on the power monitoring and analysis results, that a search instruction needs to be issued, it will immediately precisely control the signal generator according to this search instruction. As the source of signal generation, the signal generator has the ability to accurately adjust the frequency and amplitude. It will emit an alternating current carrier signal with a specific frequency and amplitude corresponding to the search instruction.

[0073] The frequency and amplitude of the alternating current carrier signal are carefully designed. A specific frequency can ensure that the signal can be stably transmitted on the alternating current power transmission line of the distribution branch, avoiding interference with other signals; an appropriate amplitude can ensure that the signal has sufficient strength to overcome line losses and noise interference, ensuring that the signal can accurately reach the target location. For example, in an LED lighting system in a large shopping mall, when searching for an idle power module, the signal generator may emit an alternating current carrier signal with a frequency of 100 kHz and an amplitude of 5 V.

[0074] The search instruction is essentially a control instruction containing specific information, but it cannot be directly transmitted on the alternating current power transmission line and needs to be converted. The system will encode and process the search instruction and convert it into a low-frequency data signal to be modulated.

[0075] This low-frequency data signal contains all the key information related to the search instruction, such as the search target, conditions, priority, etc. For example, the search instruction may require finding a power module with specific power output capabilities and an idle state, and this information will be encoded into binary data and then converted into a low-frequency electrical signal. The frequency of the low-frequency data signal is relatively low, usually between a few Hz and dozens of kHz, so that it can be effectively modulated with the alternating current carrier signal later.

[0076] Based on a preset alternating current modulation method, the system will modulate the low-frequency data signal with the alternating current carrier signal.

[0077] There are various preset AC modulation methods, and common ones include amplitude modulation (AM), frequency modulation (FM), and phase modulation (PM), etc. Different modulation methods have different characteristics and applicable scenarios, and the system will select the most suitable modulation method according to actual requirements. Taking amplitude modulation as an example, the amplitude change of the low-frequency data signal will cause the corresponding change in the amplitude of the AC carrier signal, thereby embedding the information of the low-frequency data signal into the AC carrier signal. Through this modulation process, the low-frequency data signal that could not be transmitted over long distances on the power line originally can propagate on the AC power transmission line of the distribution branch together with the AC carrier signal.

[0078] After modulation, it is necessary to couple the modulated AC signal to the AC power transmission line of the distribution branch. Coupling means connecting the modulated AC signal with the AC power signal so that they can be transmitted together on the same line.

[0079] This process requires the use of special coupling equipment, such as coupling transformers, etc. The coupling transformer can achieve electrical isolation between the modulated AC signal and the AC power signal, and at the same time can effectively inject the modulated AC signal into the power transmission line. During the coupling process, it is necessary to ensure that the modulated AC signal will not affect the normal transmission of the AC power signal, and at the same time ensure the stability and accuracy of its own signal. For example, by reasonably designing the parameters of the coupling transformer, the modulated AC signal can enter the power transmission line with the minimum loss and interference.

[0080] When the modulated AC signal is transmitted to the target position on the AC power transmission line of the distribution branch along with the AC power signal, it is necessary to extract the modulated AC signal from the AC power signal. Since the AC power signal contains a large amount of power frequency power signals and possible noise and interference signals in addition to the modulated AC signal, the extraction process requires the use of special signal extraction equipment, such as filters, etc.

[0081] The filter can separate the modulated AC signal from the complex AC power signal according to the frequency characteristics of the signal. For example, by designing a band-pass filter, only signals within a specific frequency range are allowed to pass through, thereby effectively filtering out the power frequency power signals and other interference signals and only retaining the modulated AC signal. The extracted AC signal may be contaminated by a certain degree of noise, so it also needs to be purified to improve the quality and purity of the signal.

[0082] The extracted and purified AC signal needs to be demodulated to restore it to the original low-frequency data signal.

[0083] The system will select the corresponding demodulation algorithm and circuit according to the modulation method adopted previously. For example, if amplitude modulation is used, the demodulation circuit will restore the original amplitude information of the low-frequency data signal according to the change in the amplitude of the AC signal; if frequency modulation is used, the demodulation circuit will restore the original frequency information of the low-frequency data signal according to the change in the frequency of the AC signal.

[0084] The demodulated signal is still an electrical signal containing binary data, which needs to be decoded and processed to extract the data information related to the search instruction for controlling the power output of the LED branch.

[0085] The decoding process converts the binary data into readable information according to the pre-set coding rules. For example, converting binary data into text, numbers, or other control instructions. The processing process further analyzes, judges, and arranges the decoded information to extract useful data. For example, determining the position, power parameters, etc. of the idle power module from the decoded information, and these information will be used to control the power output of the LED branch. The system will precisely adjust the power distribution of each LED branch according to these data information to achieve intelligent control of the LED lighting system.

[0086] By converting the search instruction into a signal that can be transmitted on the AC power transmission line of the distribution branch through AC modulation, the integration of power and communication is achieved. This improves the scheduling efficiency of the system. Traditional communication methods may require additional laying of communication lines, which not only increases the construction cost and construction difficulty but also causes signal transmission delay. However, through the integration of power and communication, the search instruction can be transmitted quickly and accurately in the distribution branch, and the system can obtain the required information in a timely manner, thus making power scheduling decisions quickly, improving the response speed and operation efficiency of the entire LED lighting system. It reduces the communication cost. There is no need to lay additional communication lines, reducing the investment and maintenance cost of hardware equipment. At the same time, using the existing AC power transmission line for communication gives full play to the potential of the power infrastructure and avoids waste of resources. It enhances the level of intelligent control. The system can accurately extract the data information for controlling the power output of the LED branch, and adjust the power distribution in real time according to the actual situation to achieve refined management of the LED lighting system. For example, automatically adjusting the power of the LED branch according to factors such as the lighting requirements, time, and environmental conditions in different areas to achieve energy-saving, comfortable, and efficient lighting effects.

[0087] This series of sub-steps for issuing the search instruction constructs an efficient and intelligent communication and power integration system, providing strong technical support for the scheduling of multi-channel LED power output and promoting the development of the LED lighting system towards a more intelligent and efficient direction.

[0089] An embodiment of the present application also discloses a distribution box, which is an ultra-thin and miniature intelligent distribution box. Referring to Figure 3 、 Figure 4 、 Figure 5 and Figure 6 , it includes a housing, which includes a detachable lower case 5, an upper case 7 and end caps 6. There are two symmetrically arranged end caps 6 for dust-proofing the interfaces at both ends. The housing plays a role in protecting internal components and can effectively prevent damage to internal components caused by dust, moisture and external forces. Inside the housing, there are a circuit board 1, a power driving element, an expansion compartment 8, a power supply module, a communication module and a processor.

[0090] The circuit board 1 includes a basic function module and an on-board remote control function module; different voltage power supply ports and communication interfaces for connecting expansion function boards are provided on the circuit board 1. The integrated design greatly facilitates the function management and coordination of the entire distribution box. The basic function module covers a series of basic but crucial functions such as data processing and logical operation, which is the basic guarantee for the distribution box to realize various control operations. At the same time, the circuit board 1 also has an on-board remote control function module and an antenna 4 is provided. With the high-performance antenna 4, the distribution box can realize remote control operation, and its remote control distance can reach more than 100 meters. This means that users can easily control the distribution box even when they are far away from it, greatly improving the convenience of use. Moreover, the circuit board 1 also opens communication interfaces and different voltage power supply ports. The communication interface can be seamlessly docked with various expansion function boards. Whether it is to expand a multi-functional card to realize the convenient control of third-party control software or to connect a PLC function board to realize more complex industrial automation control, it can be easily completed. The different voltage power supply ports can meet the diverse voltage requirements of the expansion function boards, providing strong support for function expansion and enabling the distribution box to be flexibly customized according to the needs of actual application scenarios.

[0091] The power driving element uses a magnetic latching relay 2. The magnetic latching relay 2 has unique advantages. It can well meet the design requirements of the thinness of the distribution box and makes an important contribution to realizing the thin and light of the distribution box. However, the magnetic latching relay 2 belongs to a holding-type action element and is not self-restoring, which brings certain potential safety hazards. To ensure the use safety, an anti-drive circuit is specifically integrated on the circuit board 1. When a power failure occurs, the anti-drive circuit can quickly play a role and automatically disconnect the magnetic latching, effectively avoiding potential safety accidents caused by accidental power-on and effectively protecting the safety of personnel and equipment.

[0092] Expansion bin 8 is used to connect expansion function boards. Users can easily connect various expansion function boards according to their actual needs. In terms of design, the expansion bin 8 fully considers safety and convenience. When the end cover 6 (expansion bin 8) is opened, the internal control components are not exposed, effectively avoiding safety problems caused by accidental touch and other reasons. Users can install multifunctional cards in the expansion bin 8 and achieve more flexible control methods with the help of third-party control software; they can also install PLC function modules and realize advanced functions such as remote control and remote wireless control by docking with the host computer software, meeting the needs of intelligent control of distribution boxes in different industries and different scenarios. It can support central control: central control can be realized without expanding any function modules. It can support AI voice control (external): AI voice dialogue control can be realized after expanding the voice control module.

[0093] The incoming and outgoing line structure is installed below the housing, and the incoming and outgoing line method is bottom-in and bottom-out; since dust prevention is required, the incoming line needs to be placed below. Compared with the traditional top-in and bottom-out method, it has significant advantages. In actual use scenarios, especially in some environments with more dust, the bottom-in and bottom-out method can effectively reduce the probability of dust entering the internal components. Once dust enters the distribution box and accumulates on the components, it is extremely easy to cause faults such as short circuits when powered on, resulting in component burnout. And this improved incoming and outgoing line method greatly reduces the risk of power-on burnout caused by dust, significantly improves the dust prevention performance of the distribution box, extends the service life of the distribution box, and ensures its stable operation. Among them, the wiring structure of the incoming and outgoing lines adopts the copper sheet 3 structure, and the copper sheet 3 is fixedly installed on the lower housing 5 using combination screws and knurled nuts and is electrically connected to the circuit board 1.

[0094] The power module includes a first power module, a second power module, and a power distribution branch. 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 idle power modules. When the system detects an increase in power demand and the existing power modules cannot meet it, the power distribution branch can quickly connect idle power modules to achieve flexible power allocation and ensure that the entire LED lighting system can always operate stably.

[0095] In this embodiment, the distribution box can achieve single-channel start-stop control whether it is 10KW / 20KW; it has a manual control start-stop method and also supports timing control. The 10KW is divided into 3 channels for control, and the 20KW is divided into 6 channels for control. That is, the first power module can supply power to 3 LED branches, and the second power module can supply power to another 3 LED branches. The idle power module is the power module of other distribution boxes in the same bus power supply.

[0096] The communication module, controlled by the processor, adopts advanced signal processing technology. By skillfully superimposing the corresponding search instruction on the power signal of the distribution branch, the efficient transmission of the search instruction is achieved. This method not only makes full use of the existing distribution branch, avoiding the cost increase and wiring complexity brought by laying additional communication lines, but also can accurately obtain the key information required to control the power output of the LED branch while transmitting the search instruction, providing strong support for realizing precise power scheduling.
