Description

Technical Field

[0001] This invention relates to the field of industrial control technology, specifically to a dual-control system and method for water and electricity based on high-precision metering and intelligent control. Background Technology

[0002] With the rapid development of modern agriculture, urban areas, and industry, the refined management and efficient utilization of hydropower resources have become crucial issues. Especially in scenarios such as large irrigation districts and distributed water supply networks, achieving timely data collection, high-precision metering, and intelligent control of hydropower data has become a pressing technical challenge for the industry. The hydropower dual-control system, by integrating functions such as water flow metering and electricity management, aims to improve resource utilization efficiency, ensure stable equipment operation, and reduce system energy consumption. In recent years, with the development of IoT technology, intelligent sensing, and edge computing, the hydropower dual-control system is gradually evolving towards multi-parameter fusion, adaptive adjustment, and remote intelligent operation and maintenance.

[0003] Traditional hydropower control systems typically employ independent metering and control architectures, resulting in a disconnect between water and electricity resource management. This leads to low operational efficiency and high management costs. Traditional hydropower metering control systems primarily rely on a combination of mechanical flow meters, independent meters, and manual inspections. They only provide cumulative functionality and cannot monitor equipment status in real time or identify abnormal power consumption. Furthermore, the accuracy of traditional mechanical flow meters drops sharply in low-flow-rate or impurity-containing water bodies. Regarding temperature control, most systems use simple temperature switches or timed fan start / stop mechanisms, lacking precise sensing and dynamic adjustment capabilities for the internal temperature field of the electrical box. Cooling methods often rely on natural convection or single-path forced air cooling, resulting in low cooling efficiency and high energy consumption, failing to meet the demands of modern intelligent hydropower system management.

[0004] Currently, existing technologies have enabled remote transmission of water and electricity data through wireless communication modules, improved water metering accuracy by using electromagnetic flow meters, and integrated electricity meters for simultaneous water and electricity metering. In terms of heat dissipation, existing solutions mostly use external fans or simple air duct designs for unidirectional cooling or fixed power operation, triggering fan start and stop via temperature sensors. However, they cannot dynamically adjust heat dissipation according to the actual heat load and lack a power regulation mechanism based on real-time heat load. Furthermore, their heat dissipation structure is still a passive design, failing to consider the impact of high-temperature environments on the long-term stability of electronic metering modules and thus unable to adapt to complex operating conditions.

[0005] Regarding the above-mentioned technical solutions, existing technologies are unable to dynamically adjust heat dissipation according to actual heat load. The high-temperature environment inside the equipment can easily cause the electronic metering module to drift or even fail, affecting the accuracy and stability of the system's long-term metering. Summary of the Invention

[0006] The purpose of this invention is to provide a water and electricity dual control system and method based on high-precision metering and intelligent control, so as to solve the problems mentioned in the background art.

[0007] Firstly, the present invention provides a dual-control system for water and electricity based on high-precision metering and intelligent control, which achieves the purpose of the invention through the following technical solution:

[0008] A dual-control system for hydropower based on high-precision metering and intelligent control, characterized by comprising the following modules:

[0009] Flow metering module: Installed in the pipeline valve control box, used to collect flow data of the pipe valves in the pipeline valve control box in real time;

[0010] Electrical metering module: Integrated in the electrical main control box, used to collect the status data of electrical equipment in the electrical main control box and the standard temperature of the electrical main control box in real time. The pipeline valve control box is connected to the electrical main control box chamber through ventilation openings and the internal heat circulation module. Pipe valves are installed in the pipeline valve control box.

[0011] Thermal management module: used to obtain the internal temperature of the pipeline valve control box and the internal temperature of the electrical main control box in real time. When the internal temperature of the electrical main control box is higher than the standard temperature of the electrical main control box, the thermal circulation module is controlled to dissipate heat according to the specified heat dissipation power.

[0012] Thermal circulation module: Used to draw air from the pipeline valve control box into the electrical main control box for air cooling according to the specified heat dissipation power, and blow air from the electrical main control box into the pipeline valve control box to form a circulating heat dissipation.

[0013] By adopting the above technical solutions, the flow metering module uses high-precision sensors to collect flow data from the valves in the pipeline valve control box in real time, achieving accurate monitoring and recording of water flow. Providing real-time flow information through a continuous data stream helps to promptly detect flow anomalies, such as leaks or blockages, thereby reducing water waste and maintenance costs. For example, in industrial or civil scenarios, this module can detect minute flow changes, prevent potential faults, and improve the overall reliability of the system. The electrical metering module collects real-time status data of electrical equipment in the electrical main control box, such as current, voltage, power factor, and standard temperature. By monitoring the operating status of electrical equipment, the system can assess equipment health and prevent overload or malfunctions. The thermal management module obtains the internal temperature of the pipeline valve control box and the internal temperature of the electrical main control box in real time. When the temperature of the electrical main control box exceeds the standard temperature, it controls the thermal circulation module to dissipate heat according to a specified heat dissipation power. This strategy... This system effectively reduces the probability of electrical equipment performance degradation or damage due to overheating. It can dynamically adjust the heat dissipation power according to the temperature difference, making the heat dissipation process efficient and energy-saving, extending equipment life and improving system temperature stability. The thermal circulation module draws air from the pipe valve control box into the main electrical control box for air cooling according to the specified heat dissipation power, and blows hot air from the main electrical control box back into the pipe valve control box, forming a circulating heat dissipation. This recycling method utilizes existing airflow to improve heat dissipation efficiency, reduces reliance on external cooling systems, reduces energy consumption, simplifies system structure, and reduces operating costs. In addition, this module promotes thermal balance between the two boxes, reduces the probability of local overheating, improves the system's thermal management capabilities, and achieves efficient and energy-saving dual control of water and electricity. It is suitable for various environments, such as data centers, industrial control systems, or intelligent buildings, and can improve resource utilization efficiency and system reliability, as well as enhance the accuracy and stability of long-term system metering.

[0014] Optionally, the thermal management module is used to acquire the internal temperature of the pipeline valve control box in real time. Internal temperature of the electrical main control box and heat generation rate of electrical equipment When the internal temperature of the electrical main control box Temperature higher than the standard temperature of the main electrical control box When the actual heat dissipation power is calculated, it is: ,in, Where C is the standard air flow rate and C is the specific heat capacity of air, if Then set the specified heat dissipation power ,like Set the maximum airflow to Calculate the required gas flow rate as follows: Let the specified heat dissipation power be The thermal circulation module controls heat dissipation according to the specified heat dissipation power P.

[0015] By adopting the above technical solution, the system can dynamically adjust its heat dissipation strategy according to the actual heat load. When the heat dissipation capacity is sufficient, the system directly uses the actual heat dissipation power, which is less likely to cause excessive heat dissipation and saves energy. When the heat dissipation capacity is insufficient, the system dissipates heat at the maximum allowable heat dissipation power. Under high heat load conditions, the system can increase the airflow to improve the heat dissipation capacity, while being limited by the maximum airflow to avoid overloading the equipment. This allows the heat dissipation power to be dynamically adjusted, precisely controlling the heat dissipation process according to real-time heat load and temperature conditions. The system only uses the necessary heat dissipation power when needed, reducing unnecessary energy consumption and improving heat dissipation efficiency. In addition, this dynamic adjustment strategy enhances the system's adaptability and reliability. Under different environmental conditions, such as seasonal changes or equipment load fluctuations, the system can automatically adjust its heat dissipation strategy to maintain optimal operating conditions, improve the system's thermal management capabilities, and achieve intelligent, efficient, and energy-saving dual control of water and electricity. It is suitable for high-load industrial scenarios, can significantly extend equipment life and improve energy utilization, and improve the accuracy and stability of long-term metering.

[0016] Optionally, a photovoltaic power generation module is also included: used to store solar energy in the battery using photovoltaic power generation. The power supply is the sum of the available photovoltaic power generation and the battery power supply. If the power supply is greater than or equal to the sum of the specified heat dissipation power and the equipment energy consumption power, the P value remains unchanged. Photovoltaic power generation is used first, and if there is surplus power, it is used to charge the battery. If the power supply is less than the sum of the specified heat dissipation power and the equipment energy consumption power, all photovoltaic power generation and battery power are used, the power gap is calculated, and power is drawn from the grid.

[0017] By adopting the above technical solution, the photovoltaic power generation module converts solar energy into electrical energy using solar photovoltaic panels and stores it in batteries. The power supply consists of the sum of available photovoltaic power generation and battery power. When the power supply is greater than or equal to the sum of the specified heat dissipation power and the equipment's energy consumption power, the system prioritizes using photovoltaic power generation and stores the remaining electrical energy in the batteries. If the power supply is insufficient, all photovoltaic power generation and battery power are used, and the power gap is calculated to draw power from the grid. This energy management strategy reduces the system's dependence on the traditional power grid by integrating renewable energy, thereby reducing operating costs and energy consumption. The utilization of photovoltaic power generation enables the system to be self-sufficient when there is sufficient sunshine, and even charges the batteries for use at night or on cloudy days, improving the system's energy independence and promoting the application of green energy. Intelligent power distribution enables... This system efficiently utilizes photovoltaic power, prioritizing its use while batteries act as a buffer to balance supply and demand fluctuations. When heat dissipation and equipment energy consumption are high, the system switches to battery and grid power, enabling continuous and stable operation. This reduces the probability of over-discharge or overcharge, extending battery life. Furthermore, this module works in conjunction with the thermal management module to ensure that the heat dissipation process does not fail due to energy shortages. In high-temperature environments, heat dissipation demand increases, but photovoltaic power generation may be insufficient. In this case, the system fills the gap through the grid, reducing the probability of heat dissipation failure due to energy shortages, improving the accuracy and stability of long-term metering, thereby maintaining the safety of electrical equipment, achieving sustainable energy utilization, and enhancing the system's environmental friendliness and economy. It is suitable for remote areas or energy-sensitive applications, significantly reducing operating costs and improving system reliability.

[0018] Optionally, a heat dissipation adjustment module is also included: used to obtain the ambient temperature change trend over a specified period based on historical temperature data and weather forecast information, and to set a target temperature difference value. When the rise in ambient temperature within a specified time period exceeds the target temperature difference, the specified heat dissipation power is corrected, and the corrected specified heat dissipation power is updated to... , where α is the prediction adjustment coefficient.

[0019] By adopting the above technical solution, and analyzing historical temperature data and weather forecasts, the environmental temperature change trend within a specified time period is obtained, thereby correcting the specified heat dissipation power. This predictive adjustment strategy, by responding in advance to changes in environmental temperature, can preventively increase heat dissipation power, reducing the probability of a sharp rise in the temperature of the main control box of electrical appliances due to external heat load. For example, when high temperatures arrive, the system can increase heat dissipation capacity in advance, ensuring that electrical equipment operates within a safe temperature range, reducing the risk of overheating, and improving the accuracy and stability of long-term metering. Especially in regions with variable climates, it can effectively cope with sudden temperature fluctuations. The correction formula is based on the temperature change ratio, allowing the system to be calibrated according to specific application scenarios, optimizing heat dissipation response, achieving more precise thermal management, reducing unnecessary energy consumption, and improving heat dissipation efficiency. This module, combined with the thermal management module, enhances the system's adaptability, achieving a balance between energy efficiency and heat dissipation effect. It is suitable for intelligent buildings or outdoor equipment, significantly reducing maintenance needs and improving system response speed.

[0020] Optionally, a dynamic adjustment module is also included: used to calculate the heat dissipation demand index. ,in The upper limit of the temperature of the main control box of the electrical appliance is set to a low heat dissipation demand index of 1. High heat dissipation demand index is ,like If so, the intermittent cooling mode is executed, and the thermal circulation module is periodically started and stopped. If the economic cooling mode is executed, the control heat circulation module will dissipate heat according to the specified heat dissipation power P. In this mode, the high-efficiency heat dissipation mode is executed, which causes the control heat circulation module to dissipate heat according to the specified heat dissipation power P, while adjusting the opening of the pipe valve in the pipeline valve control box to increase the flow rate.

[0021] By adopting the above technical solutions, the temperature deviation is quantified through the heat dissipation demand index, enabling the system to adjust its heat dissipation strategy according to actual needs. Under low demand, the intermittent heat dissipation mode reduces operating time through periodic start-stop, significantly reducing energy consumption in low-load scenarios, such as at night or when equipment is idle, reducing power consumption through intermittent operation while maintaining basic temperature control. In the economic heat dissipation mode, the system balances heat dissipation and energy consumption, providing stable cooling. Under high demand, the high-efficiency heat dissipation mode increases water flow by increasing pipe valve opening, maximizing heat dissipation capacity to meet heat dissipation needs. The high-efficiency heat dissipation mode is an emergency heat dissipation mode, an unconventional heat dissipation method that enhances heat dissipation effect by increasing flow in high-load or high-temperature environments, such as in industrial production lines or data centers, rapidly reducing temperature, lowering the probability of equipment overheating failure, and improving the accuracy and stability of long-term system metering. The dynamic adjustment module automatically switches modes to adapt the system to different operating conditions, optimize overall performance, improve heat dissipation efficiency, and extend the life of system components. It is suitable for variable load environments and can significantly improve system adaptability and economy.

[0022] Secondly, this invention provides a water and electricity dual control method based on high-precision metering and intelligent control, and applies a water and electricity dual control system based on high-precision metering and intelligent control. The system includes a flow metering module, an electrical metering module, a thermal management module, a dynamic adjustment module, and a thermal circulation module. The invention achieves its objective through the following technical solution:

[0023] A dual-control method for hydropower based on high-precision metering and intelligent control includes the following steps:

[0024] Flow measurement steps: Real-time acquisition of flow data from the valves in the pipeline valve control box;

[0025] Electrical metering steps: Real-time acquisition of status data of electrical equipment in the electrical main control box and standard temperature of the electrical main control box;

[0026] Thermal management steps: Real-time acquisition of the internal temperature of the pipeline valve control box and the internal temperature of the electrical main control box; when the internal temperature of the electrical main control box is higher than the standard temperature of the electrical main control box, a specified heat dissipation power control command is generated.

[0027] Thermal circulation steps: According to the specified heat dissipation power control command, air in the pipeline valve control box is drawn into the electrical main control box for air cooling, and at the same time, air in the electrical main control box is blown into the pipeline valve control box to form a circulating heat dissipation.

[0028] By adopting the above technical solution, high-precision sensors are used to collect flow data of pipe valves in the pipeline valve control box in real time, enabling accurate monitoring and recording of water flow. The continuous data stream provides real-time flow information, helping to promptly detect flow anomalies such as leaks or blockages, thereby reducing water waste and maintenance costs. For example, in industrial or civil scenarios, it can detect minute flow changes, prevent potential faults, and improve overall system reliability. Real-time acquisition of status data of electrical equipment in the main electrical control box, such as current, voltage, power factor, and standard temperature, allows the system to assess equipment health and prevent overload or malfunctions by monitoring the operating status of the electrical equipment. Real-time acquisition of the internal temperature of the pipeline valve control box and the main electrical control box, along with the activation of heat dissipation based on a specified heat dissipation power command when the temperature of the main electrical control box exceeds the standard temperature, effectively reduces water waste and maintenance costs. The probability of electrical equipment performance degradation or damage due to overheating can be reduced by dynamically adjusting the heat dissipation power according to the temperature difference, making the heat dissipation process efficient and energy-saving, extending equipment life and improving system temperature stability. Based on the specified heat dissipation power, air from the pipe valve control box is drawn into the main electrical control box for air cooling, and hot air from the main electrical control box is blown back into the pipe valve control box, forming a circulating heat dissipation. This recycling method utilizes existing airflow to improve heat dissipation efficiency, reduces reliance on external cooling systems, lowers energy consumption, simplifies system structure and reduces operating costs, promotes thermal balance between the two boxes, reduces the probability of local overheating, improves the system's thermal management capabilities, and achieves efficient and energy-saving dual control of water and electricity. It is suitable for various environments, such as data centers, industrial control systems, or intelligent buildings, and can improve resource utilization efficiency and system reliability, as well as enhance the accuracy and stability of long-term system metering.

[0029] Optionally, the thermal management step includes: acquiring the internal temperature of the pipeline valve control box in real time. Internal temperature of the electrical main control box Heat generation rate of electrical equipment and ambient temperature When the internal temperature of the electrical main control box Temperature higher than the standard temperature of the main electrical control box When the effective cooling source temperature is calculated, it is: Where β is the thermal influence coefficient, the actual heat dissipation power is calculated as follows: ,in, Where C is the standard air flow rate and C is the specific heat capacity of air, if Then set the specified heat dissipation power ,like Set the maximum airflow to Calculate the required gas flow rate as follows: Let the specified heat dissipation power be Generate a specified heat dissipation power control command based on the specified heat dissipation power P.

[0030] By adopting the above technical solution, the contribution of both internal circulating air and external ambient air as cooling sources is comprehensively considered, thus more realistically simulating the temperature state of the cooling medium in actual heat dissipation environments. For example, when the ambient temperature is much lower than the temperature of the pipe valve control box, such as at night or in cool seasons, a higher weight will significantly reduce the effective cooling source temperature, meaning that the system has identified a superior cooling source, which can provide stronger heat dissipation capacity under the same airflow. Conversely, in hot environments, the model can also objectively assess the rise in cooling source temperature, improving the accuracy of subsequent power calculations and reducing the probability of misjudgments that may occur based on calculations based on a single internal temperature. It can more accurately reflect the theoretical maximum heat dissipation potential of the system under the current internal and external environments. The system can dynamically and accurately adjust the heat dissipation command according to real-time changes in environmental conditions and internal heat load, reducing the probability of excessive heat dissipation under good cooling conditions, while maintaining sufficient but not excessive heat dissipation capacity even in harsh environments. This enhances the robustness and energy efficiency ratio of the system, improves resource utilization efficiency and system reliability, and enhances the accuracy and stability of long-term system metering.

[0031] Optionally, a photovoltaic power generation step and an emergency heat dissipation step are further provided between the thermal management step and the thermal circulation step;

[0032] Photovoltaic power generation steps: Storing solar energy in batteries using photovoltaic power generation, and calculating the power output. ,in, For available photovoltaic power generation, Power supply to the battery, if ,in To determine the power consumption of the equipment, the P value remains constant. Power is supplied to the thermal cycling process according to the specified heat dissipation control command, while simultaneously controlling the electrical equipment in the main electrical control box according to... Power is supplied, prioritizing photovoltaic power generation. Any remaining power is used to charge the battery and initiate a thermal cycling process. If so, then the emergency allocation procedure will be executed;

[0033] Emergency cooling procedures: Use all photovoltaic power and battery power to supply power to the thermal cycle process; the calculated power deficit is... Update the specified heat dissipation power to Where γ is the heat dissipation power adjustment coefficient, 0 < γ < 1, and at the same time, the equipment power management is activated, updating the equipment power consumption to... Power is supplied to the thermal cycling process according to the specified heat dissipation control commands, and the electrical equipment in the main electrical control box is powered according to... Provide power.

[0034] By adopting the above technical solution, when the combined power supply capacity of photovoltaics and batteries cannot meet the total demand, this method does not simply interrupt the system or rely entirely on the grid. Instead, it activates an emergency heat dissipation step and executes a power redistribution strategy. First, it utilizes all available photovoltaic and battery power, then calculates the power gap, and distributes the power gap proportionally to the heat dissipation system and equipment system through a heat dissipation power adjustment coefficient. By partially reducing heat dissipation power and equipment power consumption, it maximizes the continuation of heat dissipation cycle and equipment operation while maintaining core functions. The heat dissipation power adjustment coefficient is balanced according to system characteristics. For example, if electrical equipment is more sensitive to overheating, a larger value can be set to prioritize heat dissipation; conversely, a smaller value can be set to maintain equipment performance. This effectively reduces the probability of system downtime or equipment damage due to severe power shortages, enhances the system's survivability and reliability under abnormal operating conditions such as severe weather or energy shortages, and thus improves resource utilization efficiency and reliability.

[0035] Optionally, a dynamic adjustment step is provided between the thermal management step and the thermal cycling step: used to calculate the heat dissipation demand index. ,in The upper limit of the temperature of the main control box of the electrical appliance is set to a low heat dissipation demand index of 1. High heat dissipation demand index is ,like Then, the intermittent heat dissipation mode is executed, periodically controlling the start and stop of the thermal cycle process. Then, the economic cooling mode will be executed, based on the power supply. Dynamically adjust the specified heat dissipation power and update the specified heat dissipation power control command. If the high-efficiency heat dissipation mode is activated, continuous heat dissipation is performed according to the specified heat dissipation power P, while the opening of the pipe valve in the pipeline valve control box is adjusted to increase the flow rate.

[0036] By adopting the above technical solutions, the temperature deviation is quantified through the heat dissipation demand index, enabling the system to adjust its heat dissipation strategy according to actual needs. Under low demand, the intermittent heat dissipation mode reduces operating time through periodic start-stop, significantly reducing energy consumption in low-load scenarios, such as at night or when equipment is idle, reducing power consumption while maintaining basic temperature control. In the economic heat dissipation mode, the system balances heat dissipation and energy consumption, providing stable cooling. Under high demand, the high-efficiency heat dissipation mode increases water flow by increasing valve opening, maximizing heat dissipation capacity to meet heat dissipation needs. Under high load or high temperature environments, increasing flow enhances the heat dissipation effect, such as in industrial production lines or data centers, rapidly reducing temperature, lowering the probability of equipment overheating failure, and improving the accuracy and stability of long-term system metering. The dynamic adjustment module automatically switches modes to adapt the system to different operating conditions, optimizes overall performance, improves heat dissipation efficiency, and helps extend the lifespan of system components. It is suitable for variable load environments and can significantly improve system adaptability and economy.

[0037] Optionally, a heat dissipation adjustment step is further provided between the thermal management step and the thermal cycling step: obtaining the ambient temperature change trend over a specified period based on historical temperature data and weather forecast information, and setting a target temperature difference value. When the rise in ambient temperature within a specified time period exceeds the target temperature difference, the specified heat dissipation power is corrected, and the corrected specified heat dissipation power is updated to... , where α is the prediction adjustment coefficient.

[0038] By adopting the above technical solution, and analyzing historical temperature data and weather forecasts, the environmental temperature change trend within a specified time period is obtained, thereby correcting the specified heat dissipation power. This predictive adjustment strategy, by responding in advance to changes in environmental temperature, can preventively increase heat dissipation power, reducing the probability of a sharp rise in the temperature of the main control box of electrical appliances due to external heat load. For example, when high temperatures arrive, the system can increase heat dissipation capacity in advance, ensuring that electrical equipment operates within a safe temperature range, reducing the risk of overheating, and improving the accuracy and stability of long-term metering. Especially in regions with variable climates, it can effectively cope with sudden temperature fluctuations. The correction formula is based on the temperature change ratio, allowing the system to be calibrated according to specific application scenarios, optimizing heat dissipation response, achieving more precise thermal management, reducing unnecessary energy consumption, improving heat dissipation efficiency, enhancing the system's adaptability, and achieving a balance between energy efficiency and heat dissipation effect. It is suitable for intelligent buildings or outdoor equipment, and can significantly reduce maintenance needs and improve system response speed.

[0039] Compared with the prior art, the beneficial effects of the present invention are:

[0040] 1. High-precision sensors are used to collect real-time flow data from valves in the pipeline valve control box, enabling accurate monitoring and recording of water flow. A continuous data stream provides real-time flow information, helping to promptly detect flow anomalies such as leaks or blockages, thereby reducing water waste and maintenance costs. Real-time status data is also collected from electrical equipment in the main electrical control box, allowing the system to assess equipment health and prevent overload or malfunctions. The internal temperatures of both the pipeline valve control box and the main electrical control box are also monitored in real-time. When the temperature of the main electrical control box exceeds the standard temperature, cooling is initiated according to a specified power output command. This strategy effectively reduces the probability of performance degradation or damage to electrical equipment due to overheating and allows for dynamic adjustment based on temperature differences. The overall heat dissipation power is adjusted to make the heat dissipation process efficient and energy-saving, extend equipment life and improve system temperature stability. According to the specified heat dissipation power, air in the pipeline valve control box is drawn into the electrical main control box for air cooling, and hot air in the electrical main control box is blown into the pipeline valve control box to form a circulating heat dissipation. This recycling method utilizes existing airflow to improve heat dissipation efficiency, reduces dependence on external cooling systems, reduces energy consumption, simplifies system structure and reduces operating costs, promotes thermal balance between the two boxes, reduces the probability of local overheating, improves the system's thermal management capabilities, realizes efficient and energy-saving dual control of water and electricity, can improve resource utilization efficiency and system reliability, and improve the accuracy and stability of long-term metering of the system.

[0041] 2. The system can dynamically adjust its heat dissipation strategy based on the actual heat load. When the heat dissipation capacity is sufficient, the system directly uses the actual heat dissipation power, which is less likely to cause overheating and saves energy. When the heat dissipation capacity is insufficient, the system dissipates heat at the maximum allowable heat dissipation power. Under high heat load conditions, the system can increase the airflow to improve the heat dissipation capacity, while being limited by the maximum airflow to avoid overloading the equipment. This allows the heat dissipation power to be dynamically adjusted. The system can precisely control the heat dissipation process based on real-time heat load and temperature conditions. The system only uses the necessary heat dissipation power when needed, reducing unnecessary energy consumption and improving heat dissipation efficiency. In addition, this dynamic adjustment strategy enhances the system's adaptability and reliability. Under different environmental conditions, such as seasonal changes or equipment load fluctuations, the system can automatically adjust its heat dissipation strategy to maintain optimal operating conditions, improve the system's thermal management capabilities, and achieve intelligent, efficient, and energy-saving dual control of water and electricity. It is suitable for high-load industrial scenarios, can significantly extend equipment life and improve energy utilization, and improve the accuracy and stability of long-term metering.

[0042] 3. The photovoltaic power generation module uses solar photovoltaic panels to convert solar energy into electrical energy and store it in batteries. The power supply consists of the sum of available photovoltaic power generation and battery power. When the power supply is greater than or equal to the sum of the specified heat dissipation power and the equipment energy consumption power, the system prioritizes the use of photovoltaic power generation and stores the remaining energy in the batteries. If the power supply is insufficient, all photovoltaic power generation and battery power are used, and the power gap is calculated to draw power from the grid. This energy management strategy reduces the system's dependence on the traditional grid by integrating renewable energy, lowers operating costs and energy consumption, and improves the system's energy independence. Intelligent power distribution enables efficient energy utilization, prioritizing the use of photovoltaic power generation. At the same time, the batteries act as a buffer to balance supply and demand fluctuations. When heat dissipation and equipment energy consumption are high, the system switches to battery and grid power supply, enabling the system to operate continuously and stably. This reduces the probability of heat dissipation failure due to energy shortages, improves the accuracy and stability of long-term metering, and achieves sustainable energy utilization.

[0043] 4. By analyzing the ambient temperature change trend within a specified time period, the specified heat dissipation power can be corrected. This predictive adjustment strategy, by responding to ambient temperature changes in advance, can preventively increase heat dissipation power, reduce the probability of a sharp rise in the temperature of the main control box due to external heat load, reduce the risk of overheating, and improve the accuracy and stability of long-term metering of the system. Especially in regions with variable climates, it can effectively cope with sudden temperature fluctuations. The correction formula is based on the temperature change ratio, allowing the system to be calibrated according to specific application scenarios, reducing unnecessary energy consumption, enhancing the system's adaptability, achieving a balance between energy efficiency and heat dissipation effect, significantly reducing maintenance requirements and improving system response speed.

[0044] 5. By comprehensively considering the contributions of both internal circulating air and external ambient air as cooling sources, the system more realistically simulates the temperature state of the cooling medium in actual heat dissipation environments. This improves the accuracy of subsequent power calculations, reduces the probability of misjudgments that may occur based on calculations based on a single internal temperature, and more accurately reflects the theoretical maximum heat dissipation potential of the system under current internal and external environments. The system can dynamically and precisely adjust heat dissipation commands according to real-time changes in environmental conditions and internal heat loads, reducing the probability of excessive heat dissipation under good cooling conditions. At the same time, it maintains sufficient but not excessive heat dissipation capacity even under harsh environments, enhancing the system's robustness and energy efficiency ratio. This improves resource utilization efficiency and system reliability, and enhances the accuracy and stability of long-term metering. Attached Figure Description

[0071] The implementation principle of a dual-control system for hydropower based on high-precision metering and intelligent control in this embodiment is as follows:

[0072] The flow metering module uses high-precision sensors to collect flow data from the valves in the pipeline valve control box in real time, enabling accurate monitoring and recording of water flow. It provides real-time flow information through a continuous data stream, which helps to detect flow anomalies in a timely manner, such as leaks or blockages, thereby reducing water waste and maintenance costs. For example, in industrial or civil scenarios, this module can detect minute changes in flow, prevent potential failures, and improve the overall reliability of the system.

[0073] The electrical metering module collects real-time status data of electrical equipment in the main electrical control box, such as current, voltage, power factor, and standard temperature. By monitoring the operating status of electrical equipment, the system can assess the health status of the equipment and prevent overload or failure.

[0074] The thermal management module acquires the internal temperature of the pipeline valve control box and the internal temperature of the electrical main control box in real time. When the temperature of the electrical main control box exceeds the standard temperature, it controls the thermal circulation module to dissipate heat according to the specified heat dissipation power. This strategy effectively reduces the probability of electrical equipment performance degradation or damage due to overheating. It can dynamically adjust the heat dissipation power according to the temperature difference, making the heat dissipation process efficient and energy-saving, extending equipment life and improving system performance.

[0075] The system can dynamically adjust its heat dissipation strategy according to the actual heat load. When the heat dissipation capacity is sufficient, the system directly uses the actual heat dissipation power, which is less likely to cause excessive heat dissipation and saves energy. When the heat dissipation capacity is insufficient, the system dissipates heat at the maximum allowable heat dissipation power. Under high heat load conditions, the system can increase the airflow to improve the heat dissipation capacity, while being limited by the maximum airflow to avoid overloading the equipment. This allows the heat dissipation power to be dynamically adjusted. The system can precisely control the heat dissipation process according to the real-time heat load and temperature conditions. The system only uses the necessary heat dissipation power when needed, reducing unnecessary energy consumption and improving heat dissipation efficiency.

[0076] Furthermore, this dynamic adjustment strategy enhances the system's adaptability and reliability. Under different environmental conditions, such as seasonal changes or equipment load fluctuations, the system can automatically adjust its heat dissipation strategy to maintain optimal operating conditions, improve the system's thermal management capabilities, and achieve intelligent, efficient, and energy-saving dual control of water and electricity. It is suitable for high-load industrial scenarios, can significantly extend equipment life and improve energy utilization, and enhance the accuracy and stability of long-term metering.

[0077] The photovoltaic power generation module uses solar photovoltaic panels to convert solar energy into electrical energy and store it in the battery. The power supply consists of the sum of the available photovoltaic power generation and the battery power supply. When the power supply is greater than or equal to the sum of the specified heat dissipation power and the equipment energy consumption power, the system prioritizes the use of photovoltaic power generation and stores the remaining electrical energy in the battery. If the power supply is insufficient, all photovoltaic power generation and battery power are used, and the power gap is calculated to draw power from the grid.

[0078] This energy management strategy reduces the system's dependence on the traditional power grid by integrating renewable energy sources, thereby lowering operating costs and energy consumption. The use of photovoltaic power generation enables the system to be self-sufficient when there is sufficient sunshine, and can even charge the battery for use at night or on cloudy days, improving the system's energy independence and promoting the application of green energy.

[0079] Intelligent power distribution enables efficient energy utilization, prioritizing the use of photovoltaic power generation. At the same time, the battery acts as a buffer storage, balancing supply and demand fluctuations. When heat dissipation and equipment energy consumption are high, the system switches to battery and grid power supply, enabling the system to operate continuously and stably, reducing the probability of over-discharge or over-charge, and extending battery life.

[0080] Furthermore, this module works in conjunction with the thermal management module to ensure that the heat dissipation process does not fail due to energy shortages. In high-temperature environments, the demand for heat dissipation increases, but photovoltaic power generation may be insufficient. At this time, the system makes up the gap through the power grid, reducing the probability of heat dissipation failure due to energy shortages, improving the accuracy and stability of long-term metering, thereby maintaining the safety of electrical equipment, realizing the sustainable use of energy, enhancing the environmental friendliness and economy of the system, and making it suitable for remote areas or energy-sensitive applications. It can significantly reduce operating costs and improve system reliability.

[0081] By analyzing historical temperature data and weather forecasts, the trend of ambient temperature changes within a specified period can be obtained, thereby correcting the specified heat dissipation power. This predictive adjustment strategy can preventively increase heat dissipation power by responding to changes in ambient temperature in advance, reducing the probability of the main control box temperature of the electrical appliance rising sharply due to external heat load.

[0082] For example, when high temperatures arrive, the system can improve its heat dissipation capacity in advance, so that electrical equipment can operate within a safe temperature range, reducing the risk of overheating and improving the accuracy and stability of long-term metering. Especially in regions with variable climates, it can effectively cope with sudden temperature fluctuations.

[0083] The correction formula is based on the temperature change ratio, allowing the system to be calibrated according to specific application scenarios, optimizing heat dissipation response, achieving more precise thermal management, reducing unnecessary energy consumption, and improving heat dissipation efficiency. When combined with the thermal management module, this module enhances the system's adaptability, achieving a balance between energy efficiency and heat dissipation effect. It is suitable for smart buildings or outdoor equipment, and can significantly reduce maintenance requirements and improve system response speed.

[0084] By quantifying the degree of temperature deviation through the heat dissipation demand index, the system can adjust its heat dissipation strategy according to actual needs. Under low demand, the intermittent heat dissipation mode reduces running time through periodic start-stop, significantly reducing energy consumption in low-load scenarios, such as at night or when equipment is idle. It reduces power consumption through intermittent operation while maintaining basic temperature control. In the economic heat dissipation mode, the system balances heat dissipation and energy consumption, providing stable cooling. Under high demand, the high-efficiency heat dissipation mode increases water flow by increasing the opening of pipe valves, maximizing heat dissipation capacity to meet heat dissipation needs.

[0085] In high-load or high-temperature environments, increasing flow enhances heat dissipation, such as in industrial production lines or data centers. This can quickly reduce temperature, decrease the probability of equipment overheating failure, and improve the accuracy and stability of long-term metering. The dynamic adjustment module automatically switches modes to adapt the system to different operating conditions, optimize overall performance, improve heat dissipation efficiency, and extend the lifespan of system components. It is suitable for variable load environments and can significantly improve system adaptability and economy.

[0086] The thermal circulation module draws air from the pipe valve control box into the electrical main control box for air cooling according to the specified heat dissipation power, and blows the hot air from the electrical main control box back into the pipe valve control box to form a circulating heat dissipation. This recycling method improves heat dissipation efficiency by utilizing existing airflow, reduces reliance on external cooling systems, reduces energy consumption, simplifies system structure, and reduces operating costs.

[0087] In addition, the thermal circulation module promotes thermal balance between the two enclosures, reduces the probability of local overheating, improves the system's thermal management capabilities, and achieves efficient and energy-saving dual control of water and electricity. It is suitable for various environments, such as data centers, industrial control systems, or smart buildings, and can improve resource utilization efficiency and system reliability, as well as enhance the accuracy and stability of long-term metering.

Provide power.

[0097] The implementation principle of this embodiment of a dual-control method for water and electricity based on high-precision metering and intelligent control is as follows:

[0098] By collecting flow data of pipe valves in the pipeline valve control box in real time through high-precision sensors, the water flow can be accurately monitored and recorded. The continuous data stream provides real-time flow information, which helps to detect flow anomalies in a timely manner, such as leaks or blockages, thereby reducing water waste and maintenance costs.

[0099] For example, in industrial or civilian applications, it can detect minute changes in flow rate, prevent potential faults, and improve the overall reliability of the system. It can also collect real-time status data of electrical equipment in the main control box, such as current, voltage, power factor, and standard temperature. By monitoring the operating status of the electrical equipment, the system can assess the health of the equipment and prevent overloads or malfunctions.

[0100] The system acquires the internal temperatures of the pipeline valve control box and the electrical main control box in real time. When the temperature of the electrical main control box exceeds the standard temperature, it generates instructions based on the specified heat dissipation power to dissipate heat. This strategy effectively reduces the probability of electrical equipment performance degradation or damage due to overheating. It can dynamically adjust the heat dissipation power according to the temperature difference, making the heat dissipation process efficient and energy-saving, extending equipment life and improving system performance.

[0101] By comprehensively considering the contributions of both internal circulating air and external ambient air as cooling sources, the model more realistically simulates the temperature state of the cooling medium in actual heat dissipation environments. For example, when the ambient temperature is much lower than the temperature of the pipe valve control box, such as at night or in cool seasons, a higher weight will significantly reduce the effective cooling source temperature, meaning that the system has identified a superior cooling source, thus providing stronger heat dissipation capacity under the same airflow. Conversely, in hot environments, the model can also objectively assess the rise in cooling source temperature, improving the accuracy of subsequent power calculations and reducing the probability of misjudgments that may occur based on calculations based on a single internal temperature. This allows the model to more accurately reflect the theoretical maximum heat dissipation potential of the system under the current internal and external environments.

[0102] By quantifying the degree of temperature deviation through a heat dissipation demand index, the system can adjust its heat dissipation strategy according to actual needs. Under low demand, the intermittent heat dissipation mode reduces operating time through periodic start-stop, significantly reducing energy consumption in low-load scenarios, such as at night or when equipment is idle. This reduces power consumption while maintaining basic temperature control. In the economic heat dissipation mode, the system balances heat dissipation and energy consumption, providing stable cooling. Under high demand, the high-efficiency heat dissipation mode increases water flow by increasing valve opening, maximizing heat dissipation capacity to meet heat dissipation needs. Under high load or high temperature environments, increasing flow enhances the heat dissipation effect.

[0103] For example, in industrial production lines or data centers, it can quickly reduce temperature, decrease the probability of equipment overheating failure, improve the accuracy and stability of long-term metering, and the dynamic adjustment module can automatically switch modes to adapt the system to different operating conditions, optimize overall performance, improve heat dissipation efficiency, extend the life of system components, and is suitable for variable load environments, which can significantly improve the system's adaptability and economy.

[0104] By analyzing historical temperature data and weather forecasts, the trend of ambient temperature changes within a specified period can be obtained, thereby correcting the specified heat dissipation power. This predictive adjustment strategy can preventively increase heat dissipation power by responding to changes in ambient temperature in advance, reducing the probability of the main control box temperature of the electrical appliance rising sharply due to external heat load.

[0105] For example, when high temperatures arrive, the system can improve its heat dissipation capacity in advance, so that electrical equipment can operate within a safe temperature range, reducing the risk of overheating and improving the accuracy and stability of long-term metering. Especially in regions with variable climates, it can effectively cope with sudden temperature fluctuations.

[0106] The correction formula is based on the temperature change ratio, allowing the system to be calibrated according to specific application scenarios, optimizing heat dissipation response, achieving more precise thermal management, reducing unnecessary energy consumption, improving heat dissipation efficiency, enhancing the system's adaptability, and achieving a balance between energy efficiency and heat dissipation effect. It is suitable for smart buildings or outdoor equipment, and can significantly reduce maintenance needs and improve system response speed.

[0107] The system can dynamically and accurately adjust the heat dissipation command according to the real-time changes in environmental conditions and internal heat load, reducing the probability of excessive heat dissipation when the cooling conditions are good, while maintaining sufficient but not excessive heat dissipation capacity in harsh environments. This enhances the robustness and energy efficiency ratio of the system, improves resource utilization efficiency and system reliability, and enhances the accuracy and stability of long-term metering.

[0108] When the combined power supply capacity of photovoltaics and batteries cannot meet the total demand, this method does not simply interrupt the system or rely entirely on the grid. Instead, it activates an emergency cooling step and executes a power redistribution strategy. First, it utilizes all available photovoltaic and battery power, then calculates the power gap, and distributes the power gap proportionally to the cooling system and equipment system through a cooling power adjustment coefficient. By partially reducing the cooling power and equipment power consumption, the cooling cycle and equipment operation are extended to the maximum extent while maintaining the core functions without interruption. The cooling power adjustment coefficient is weighed according to the system characteristics.

[0109] For example, if electrical equipment is more sensitive to overheating, a larger value can be set to prioritize heat dissipation; conversely, a smaller value can be set to maintain equipment performance. This effectively reduces the probability of system downtime or equipment damage due to severe power shortages, enhances the system's survivability and reliability under abnormal operating conditions such as severe weather or energy shortages, and thus improves resource utilization efficiency and reliability.

[0110] According to the specified heat dissipation power, air from the pipe valve control box is drawn into the electrical main control box for air cooling, and hot air from the electrical main control box is blown back into the pipe valve control box, forming a circulating heat dissipation. This recycling method improves heat dissipation efficiency by utilizing existing airflow, reduces reliance on external cooling systems, lowers energy consumption, simplifies system structure and reduces operating costs, promotes thermal balance between the two boxes, reduces the probability of local overheating, improves the system's thermal management capabilities, and achieves efficient and energy-saving dual control of water and electricity. It is suitable for various environments, such as data centers, industrial control systems or intelligent buildings, and can improve resource utilization efficiency and system reliability, as well as enhance the accuracy and stability of long-term metering.

[0111] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
