[0001] This application is a divisional application of application filed on October 10, 2025, with application number 2025114430874 and invention title "Intelligent Track Socket Reservation Control Method and System". Technical Field

[0002] This invention belongs to the field of intelligent track socket management technology, specifically relating to an intelligent track socket reservation control method and system. Background Technology

[0003] With the deep integration of intelligent manufacturing and industrial Internet of Things technologies, intelligent power management of production equipment has become a core link in ensuring production continuity and improving energy efficiency. As a flexible and scalable end-point power distribution device, intelligent track sockets play a key role in scenarios such as automated production lines, data centers and intelligent buildings. They not only realize convenient power access, but also carry out important functions of intelligent monitoring and scheduling management of electrical equipment.

[0004] However, in terms of power overload handling mechanisms, traditional solutions often directly adjust, postpone, or even cancel users' scheduled tasks based on preset fixed rules when it is predicted that power overload may occur within the scheduled time period. This ignores the priority differences of different electrical equipment in actual production and the user's true intentions, which may lead to the unwarranted interruption of the operation plan of critical equipment, seriously affecting the production cycle and the certainty of task execution.

[0005] In view of this, the industry urgently needs a smart track socket reservation control method and system. Summary of the Invention

[0006] The purpose of this invention is to provide a smart track socket reservation control method and system that can provide users with a backup plan in the event of power overload during the reserved time period of the electrical equipment, so as to ensure that the operation plan of the electrical equipment is not disrupted.

[0007] This invention is achieved through the following technical solution: A method for controlling the reservation of smart track sockets includes: Determine the power state of a power node associated with at least one electrical device, the power state including a power non-overload state and a power overload state; In response to determining the power state, a final operating plan for the at least one electrical device is generated, wherein when the power state is the power non-overload state, the final operating plan is generated based on the operating segments of the at least one electrical device, and when the power state is the power overload state, a backup plan is generated based on the delay requirements and delay conditions of the at least one electrical device, and the operating plan is adjusted based on the backup plan to obtain the final operating plan; In addition, according to the final operation plan, the power supply to or power off of the at least one electrical device is controlled.

[0008] For example, the delay requirement includes a division of the operating phases of the electrical equipment, the division of the operating phases including: The operation phases of electrical equipment are divided into the pre-operation phase, which is an uninterrupted area, and the post-operation phase, which is an intermittent area. The preset tolerance time is added based on the intermittent area to calculate the allowable delay value.

[0009] For example, the step of generating the backup plan further includes the step of evaluating the delay conditions, the step including: Arrange the electrical equipment with time delay requirements in descending order of their operating power; For the sorted electrical equipment, the planned start time of each device is delayed in turn, and the node power of the power node is recalculated each time the delay is tested. In addition, the first delay time point that makes the node power less than or equal to the socket capacity is determined as the delay node, so as to determine that the delay condition is met.

[0010] For example, the step of determining the power state of the power node includes: Obtain the node power of the power node; Obtain the socket capacity corresponding to the power node; In addition, the node power is compared with the socket capacity to determine the power status.

[0011] For example, the step of obtaining the node power of the power node includes: Determine the time point for node power assessment; Identify all electrical devices that are used at the node power assessment time point during their runtime. In addition, the operating power of all the electrical devices is summed to obtain the node power.

[0012] For example, the step of obtaining the socket capacity corresponding to the power node includes: Obtain the rated capacity of the socket corresponding to the power node as the base capacity; Furthermore, the base capacity is dynamically adjusted based on the actual voltage deviation to obtain the socket capacity.

[0013] For example, the step of dynamically adjusting the basic capacity includes: Obtain the rated voltage of the power grid and the current voltage of the electrical equipment being used; Calculate the voltage difference between the rated voltage and the current voltage; Multiply the voltage difference by a preset scaling factor to obtain the adjustment value; And, the adjustment value is subtracted from the base capacity to obtain the socket capacity.

[0014] This application also provides an intelligent track socket reservation control system, including: A power status monitoring module is used to determine the power status of a power node associated with at least one electrical device, the power status including a power non-overload state and a power overload state. An operation planning module is configured to generate a final operation plan for the at least one electrical device in response to the power state, wherein when the power state is a non-overload state, the operation planning module generates the final operation plan based on the operating segments of the at least one electrical device, and when the power state is an overload state, a backup plan is generated based on the delay requirements and delay conditions of the at least one electrical device, and the operation planning module adjusts the operation plan based on the backup plan to obtain the final operation plan; And, an equipment control module, used to control the power supply or power off of the at least one electrical device according to the final operation plan.

[0015] This application also provides an electronic device including a memory and a processor, wherein the memory stores a computer program executed by the processor, and the computer program, when executed by the processor, causes a device on which the processor is installed to perform the method described above.

[0016] This application also provides a storage medium storing a computer program that runs on a computer and causes the computer to perform the methods described above when it runs. Beneficial effects

[0017] This invention acquires the operating power and operating time of each electrical device, and calculates the operating power of concurrently operating electrical devices at the node power assessment time point to obtain the node power. This node power is compared with the socket capacity to predict the power status. When the predicted power status is an overload state, a backup plan is generated to adjust the operating schedule. Thus, it achieves predictive management and proactive control of power nodes, transforming power management into proactive avoidance. By resolving the problem through intelligent scheduling before power overload occurs, it avoids unexpected equipment shutdowns, operational interruptions, and electrical safety risks caused by power overload, thereby improving the operational stability and safety of the power supply system.

[0018] This invention uses the rated capacity as the base capacity when determining the socket capacity, and dynamically adjusts the base capacity based on the actual voltage deviation. It calculates the voltage difference between the rated voltage and the current voltage, and corrects the base capacity based on this difference, thereby obtaining the actual socket capacity that matches the current operating conditions. Since grid voltage fluctuations affect the actual carrying capacity of the line, this invention uses real-time voltage compensation to make the socket capacity assessment more consistent with physical reality, effectively avoiding operational delays or overload risks caused by capacity misjudgment, and enhancing the reliability of the control strategy.

[0019] This invention generates backup plans based on delay requirements and conditions when handling power overload conditions. The method divides the operating phases of electrical equipment, distinguishing between uninterrupted and intermittent regions, and assesses delay conditions accordingly. By conducting delay tests on the electrical equipment, it identifies delay nodes or joint delay nodes that can resolve power overload, generating backup plans to adjust the operating schedule. While ensuring power safety, this invention achieves flexible adjustment of the operating schedule for electrical equipment, considering the different continuity requirements of equipment in different operating phases. It avoids uniform delay or interruption strategies, ensuring that critical operating phases are unaffected and reducing the interference of power scheduling on normal equipment operation.

[0020] Figure 1 This is a flowchart of the method of the present invention. Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining the invention and are not intended to limit the scope of protection of the invention. Example

[0022] This embodiment provides an intelligent track socket reservation control method, applied to the centralized management of multiple electrical devices within the same track socket system. Based on the centralized scheduling capabilities of an industrial intelligent gateway for electrical devices, and combined with the power carrying characteristics of the track socket, this method can effectively identify the node power constituted by different electrical devices at different operating stages, preventing power nodes from being in a power overload state, and supporting the intelligent generation and execution of backup plans. The method specifically includes the following steps: Step S100: Determine the power state of a power node associated with at least one electrical device, the power state including a power non-overload state and a power overload state; Step S200: In response to determining the power state, a final operating plan for the at least one electrical device is generated, wherein when the power state is the power non-overload state, the final operating plan is generated based on the operating segments of the at least one electrical device, and when the power state is the power overload state, a backup plan is generated based on the delay requirements and delay conditions of the at least one electrical device, and the operating plan is adjusted based on the backup plan to obtain the final operating plan; Step S300: According to the final operation plan, control the power supply or power cut-off of the at least one electrical device.

[0023] Specifically, the industrial smart gateway automatically scans all electrical devices connected to the smart track socket, obtaining their unique identification numbers. It also collects the name, current standby or operating status, operating power, and user-defined operating segments for each device. The operating power can be the device's nominal power or the average or peak power recorded in historical operating data. Additionally, it acquires delay requirement information related to backup plans. These delay requirements are specific to each device and include parameters regarding the adjustability of its operating sequence. These parameters include the device's total operating time, operating phase divisions, and operating status judgment rules. Operating phase divisions refer to dividing a single complete operating process of the device into multiple different continuous time periods with specific constraints, based on its technological or functional characteristics. This information serves as the foundational parameters for subsequent intelligent scheduling.

[0024] Furthermore, based on the obtained device number information, the bus number to which the device belongs is determined in the preset topology. In the smart track socket system, a physical track may contain multiple parallel power supply buses, each carrying several sockets. Therefore, based on the bus number, the specific power node to which the device is connected can be further determined. A power node is a logical or physical aggregation point on a power supply bus in the smart track socket system. The power load of this point represents the total power of all devices on one or more sockets it carries.

[0025] To improve the accuracy and safety of power assessment, the socket capacity corresponding to the power node is dynamically adjusted rather than being a fixed value. This means the socket capacity is a dynamic assessment of the maximum power the power node can handle under the current grid voltage, ensuring safety. Specifically, the factory rated capacity of the socket corresponding to the power node is obtained and determined as the base capacity, serving as the benchmark for calculating the dynamic socket capacity. Considering that grid voltage fluctuations affect the actual load-bearing capacity of the socket, the base capacity is dynamically adjusted based on the actual voltage deviation. The specific adjustment steps are as follows: obtain the grid's rated voltage; obtain the current voltage of the currently measured electrical equipment; calculate the voltage difference between the rated voltage and the current voltage; multiply the voltage difference by a preset proportional coefficient to obtain the adjustment value. This preset proportional coefficient is a safety margin factor set according to safety regulations and experience, used to quantify the impact of voltage deviation on the actual load-bearing capacity of the socket. This adjustment value reflects the change in load-bearing capacity caused by grid voltage fluctuations; subtract the adjustment value from the base capacity to obtain the socket capacity. This dynamic adjustment mechanism ensures that overload judgment remains conservative and safe even when the voltage is low.

[0026] This implementation requires precise calculation of nodal power at any future time. Specifically, the planned start and stop times of all electrical equipment are used as key nodal power assessment time points. At each nodal power assessment time point, all electrical equipment whose operating time includes that time point is identified, and the operating power of these electrical equipment is summed to obtain the nodal power at that time point. By calculating all key time points, a complete future power load curve can be constructed.

[0027] Furthermore, the calculated node power at each time point is compared with the socket capacity obtained above to determine the power status, which is used to characterize the judgment result of the load safety level of the power node; if the node power is less than the socket capacity at a certain time point, the power status at that time point is determined to be a non-overload state; if the node power is greater than or equal to the socket capacity, it is determined to be an overload state.

[0028] When a power overload is detected, the plan is not immediately terminated. Instead, the persistence of the overload is further analyzed, and the changes in node power over subsequent time are monitored. This involves extrapolating along the power load curve to determine the future time point when the node power first falls below the socket capacity. To avoid frequent start-stops of electrical equipment at critical points, a preset buffer period is added to this future time point to determine the delay execution time. If this future time point cannot be determined within the preset monitoring period, the current power state is defined as a continuous overload state. In other words, if the node power cannot recover to below the socket capacity on its own within the preset monitoring period, it indicates a severe power conflict that cannot be resolved by a short-term delay.

[0029] It should be noted that the preset buffer duration is a time margin set to avoid frequent start-stop of electrical equipment near the power critical point. This duration is added to the expected time point when the overload state is lifted to determine the final delay execution time. The delay execution time is a future time point that is calculated and determined after the power overload state is detected, which postpones the start time of a certain electrical equipment.

[0030] When the power status is determined to be an overload state, but not a sustained overload state, the backup plan generation process is initiated. The backup plan is an alternative operating plan containing specific delay operation suggestions, generated when a power overload state is detected and the delay condition is met, to eliminate power conflicts. This step requires evaluating whether the delay condition is met, and sorting all electrical equipment operating during the overload period and requiring delays in descending order of their operating power to ensure that electrical equipment with higher delayed operating power can reduce node power most quickly and effectively. The delay condition is a criterion that must be met before a backup plan can be generated; that is, by extrapolating the delayed start-up of one or more electrical equipment, at least one time point can be found that prevents the node power from becoming overloaded.

[0031] Further, in the testing phase, the planned startup times of the sorted electrical devices are sequentially tested for delay. For example, the startup time of the device with the highest operating power might be delayed by a preset minimum time unit. During each delay test, the node power of that power node is recalculated based on the new operating segment. The first delay point that makes the node power less than or equal to the socket capacity is determined and designated as the delay node to resolve the power overload issue. If a delay node is successfully found, the delay condition is considered valid. If, after testing all preset delay time points for that device, the node power still consistently exceeds the socket capacity, the next device is tested. If all delay options for all delayable devices fail to resolve the overload, the delay condition is considered invalid. In some complex scenarios, if delaying the planned startup times of at least two devices simultaneously is necessary to resolve the overload, the corresponding combination of delay time points is determined as a joint delay node.

[0032] When generating backup plans, it is also necessary to handle the delay requirements of each electrical device in a refined manner. For example, for some production equipment, its operation is divided into a pre-operation phase and a post-operation phase. The pre-operation phase, such as the equipment's preheating or initial calibration phase, is defined as an uninterrupted area, which does not allow any interruption or delay. The post-operation phase, such as the equipment's stable processing phase, is defined as an intermittent phase, which is a specific period of time that can be delayed. Based on this intermittent phase, a preset tolerance time is added to calculate the total allowable delay value for the electrical device.

[0033] The preset tolerance time is an additional time factor added to the interruptible zone to calculate the final allowable delay value, providing greater scheduling flexibility. The allowable delay value is calculated based on the interruptible zone and preset tolerance time of the electrical equipment, representing the maximum total delay execution time that the equipment can withstand.

[0034] When all power nodes are in a non-overloaded state at all times, the operation plan is generated directly according to the user-defined operating period and determined as the final operation plan. The final operation plan is a sequence of power-conflict-free power equipment operation scheduling instructions that is finally determined and issued for execution after system power status assessment and necessary backup plan adjustments.

[0035] When the power status is overloaded and the delay conditions determined in the above steps are met, a backup plan is generated. The initial operating plan is then adjusted based on this backup plan to obtain the final operating plan. The backup plan is generated based on predetermined delay nodes or combined delay nodes. The initial operating plan is a raw operating arrangement generated entirely based on the user-defined operating periods for each electrical device, without power status verification. To provide a good human-machine interaction, a prompt message containing delay options is generated. For example, the message clearly indicates which electrical device is recommended to be delayed and for how long. The allowable delay value for that device is also output to the user interface along with the prompt message for operator reference and decision-making. Operators can choose from the recommended backup plans, or the system can automatically determine the optimal plan based on preset rules to obtain the final operating plan.

[0036] In this embodiment, the industrial intelligent gateway generates a specific sequence of control commands based on the determined final operation plan. The commands are sent to the control unit of the intelligent track socket through the industrial bus to control the power on or off of each power node, thereby realizing automated and precise scheduled control of each electrical device.

[0037] In actual operation, users can also view data such as the overall node power trend, operation plan adjustment history, number of power overload state triggers, and actual intervention effect of backup schemes through the built-in visualization panel of the industrial intelligent gateway or the cloud backend, so as to further optimize production scheduling and energy consumption management. Example

[0038] This embodiment provides an intelligent rail socket reservation control system. This system executes the intelligent rail socket reservation control method described above, intelligently monitoring the power status of power nodes and, based on preset operating plans and backup schemes, reserving and intelligently scheduling multiple electrical devices connected to the intelligent rail socket to prevent power overload and ensure power safety and efficiency. The system can be divided into the following collaboratively working modules: The power status monitoring module determines the power status of power nodes associated with at least one electrical device in real time or periodically, and outputs the determined power status (i.e., non-overload or overload state) to the operation planning module. Specifically: it acquires the node power of the power node, determines a node power assessment time point, which can be the scheduled start time of a newly added electrical device or the current time of a periodic system inspection; it identifies that the preset operating period of the node at the power assessment time point includes all electrical devices at that time point; and it arithmetically sums the operating power of each of these electrical devices to obtain the node power at that time point.

[0039] Specifically, the socket capacity corresponding to the power node is obtained. To more accurately assess the load-bearing capacity, a dynamic adjustment mechanism is adopted. The rated capacity of the smart track socket corresponding to the power node is obtained as the base capacity (e.g., a socket with a nominal value of 2500W). At the same time, the rated voltage of the power grid (e.g., 220V) and the current voltage of the electrical equipment are obtained through built-in or external voltage sensors. The voltage difference between the rated voltage and the current voltage is calculated, and the voltage difference is multiplied by a preset proportional coefficient to obtain the adjustment value. The adjustment value is subtracted from the base capacity to obtain the socket capacity. The calculated node power is compared with the socket capacity. If the node power is less than the socket capacity, the power status is determined to be a non-overload state. If the node power is greater than or equal to the socket capacity, the power status is determined to be an overload state.

[0040] The operation planning module receives power status information from the power status monitoring module and generates a final operation plan for at least one electrical device. Specifically, it handles the received power status in two ways: when the received power status is non-overloaded, it indicates the current operation plan is safe and requires no adjustment. In this case, the user-defined or system-default runtime segment for at least one electrical device is directly adopted as the final operation plan and transmitted to the device control module. When the received power status is overloaded, it indicates a safety risk if the initial operation plan is executed. In this case, an emergency adjustment mechanism is activated to adjust the initial operation plan based on a backup plan.

[0041] The process of adjusting the initial operation plan based on a backup plan specifically includes: generating a backup plan based on the delay requirements and delay conditions of at least one electrical device; for delay requirements, it is permissible to define the operation phase division for a specific electrical device, for example, dividing the operation phase of a device requiring preheating into a pre-operation phase (preheating phase) as an uninterrupted zone and a post-operation phase (formal operation phase) as an intermittent zone; a preset tolerance duration can be added based on the intermittent zone to calculate an allowable delay value for the device; evaluating the delay conditions to determine a specific adjustment strategy; and ensuring that all devices at the node power assessment time point are within the specified range. Electrical equipment that is in operation and has a delay requirement is sorted in descending order of its operating power. Starting with the equipment with the highest power, the planned start time of each equipment is delayed sequentially (the delay duration is within the allowable delay range). During each delay test, the node power of the delayed power node is recalculated. This testing process continues until the first delay time point that makes the node power less than the socket capacity is determined. This time point is determined as the delay node, indicating that the delay condition is met. Based on the determined delay node, a backup plan is generated, and the operating time of one or more electrical equipment is adjusted based on the backup plan to obtain the final operating plan.

[0042] The equipment control module transforms the final operation plan generated by the operation planning module into actual control of the physical equipment. It receives the final operation plan, which clearly defines the precise planned start and stop times for each associated electrical device. It continuously monitors the current time through an internal clock or synchronous network time. When the time reaches the planned start time of a certain electrical device in the final operation plan, it sends a power-on command to the smart track socket where the device is located through a control interface (such as a relay, wireless communication protocol, etc.) to connect the power supply to the electrical device. Similarly, when the time reaches the stop time of the electrical device, it sends a power-off command to cut off its power supply, ensuring that the actual operation of all electrical devices strictly follows the final operation plan that has been safely verified and optimized.

[0043] This embodiment, through the coordinated operation of the aforementioned power status monitoring module, operation planning module, and equipment control module, enables intelligent and precise scheduled control of multiple electrical devices on the smart track socket. It not only prevents overload risks caused by power superposition but also automatically adjusts the initial operation plan through a backup scheme when a power overload occurs. Under the premise of ensuring power safety, it maximizes the satisfaction of users' power needs and is suitable for various scenarios that require centralized management and scheduling of multiple high-power devices to ensure power supply stability and safety.
