Description

Technical Field

[0001] This invention relates to the field of air conditioning and ventilation control technology, and in particular to a control method, system, electronic equipment, and medium for a converter valve hall air conditioning system. Background Technology

[0002] With the rapid development of high-voltage direct current (HVDC) transmission technology and the large-scale grid connection of renewable energy, my country's West-to-East Power Transmission strategy continues to advance. As a key node in the HVDC transmission system, the converter station's operational stability and energy efficiency directly affect the safety and economy of the power grid. The converter valve hall is the core building of the converter station. The converter valves arranged inside continuously emit a large amount of heat during the power conversion process, causing a significant increase in indoor temperature. If this is not controlled, it will endanger the insulation performance and service life of the electrical equipment.

[0003] In the field of air conditioning and ventilation control, existing technologies have attempted to reduce energy consumption by introducing natural cooling sources. For example, existing technology (authorization announcement number CN103574812B) discloses a direct-ventilation air conditioning system for a computer room and its control method. This system monitors the enthalpy and humidity of fresh air, adopting a fresh air cooling mode in low-temperature seasons and switching to a compressor cooling mode in high-temperature seasons to fully utilize outdoor natural cooling sources. This method controls the air supply parameters by adjusting the opening ratio of fresh air and return air valves and employs a multi-module redundancy design to improve reliability. However, this technology is mainly aimed at relatively stable thermal environments such as data centers, and its control logic relies on the comparison of the enthalpy values ​​of fresh air and indoor air, without fully considering special scenarios involving high heat and continuous heat dissipation. Specifically, the heat load inside the converter valve hall is significantly higher than that of a typical server room, and a low-temperature environment must be maintained year-round. Traditional dual-mode control is ill-suited to handle the complex operating conditions during transitional seasons and winter. On the one hand, the return air temperature in the flexible DC converter valve hall is consistently high (reaching above 35°C), and relying solely on fresh air cooling may result in insufficient cooling or excessive cooling due to fluctuations in outdoor temperature. On the other hand, existing control methods lack fine-tuning of the linkage between return air status and natural cold source, failing to maximize the utilization of natural cold source while ensuring accurate temperature and humidity control. This leads to the refrigeration unit operating at high load for extended periods, resulting in persistently high energy consumption. These issues highlight the insufficient adaptability of existing air conditioning control technology in high-heat-load, year-round cooling scenarios, highlighting the technical contradiction between energy efficiency and operational stability. Therefore, existing air conditioning control methods suffer from low natural cold source utilization efficiency in high-heat-load environments such as flexible DC converter valve halls. Summary of the Invention

[0008] In response to the occurrence of a preset number of monitoring points where the humidity deviation meets the preset deviation conditions, the target area is identified in the converter valve hall. The target area refers to the over-humidified or over-dry area that needs to be humidified.

[0009] The real-time temperature deviation is obtained by comparing the return air temperature change rate with the temperature fluctuation threshold, and the coupling strength between temperature and humidity is calculated based on the real-time temperature deviation and the humidity deviation threshold.

[0010] Based on the deviation acceleration of the return air temperature from the set temperature, the coupling strength between temperature and humidity, and the environmental uniformity within the valve hall characterized by the target area, a control mode switching command for the air conditioning system is generated.

[0011] According to a second aspect, the present invention provides a control system for a converter valve hall air conditioning system, comprising: The valve hall temperature and humidity sequence acquisition module is used to acquire the return air temperature sequence and the outdoor ambient temperature sequence in the converter valve hall.

[0012] The valve hall operating parameter calculation module is used to calculate the valve hall operating parameters based on the return air temperature sequence and the outdoor ambient temperature sequence. The valve hall operating parameters include the return air temperature change rate and the contribution ratio of the cold source.

[0013] The temperature and humidity threshold generation module is used to determine the target operating mode based on the comparison between the return air temperature sequence and the outdoor ambient temperature sequence when the contribution of the cold source exceeds the preset proportion threshold, and to generate the temperature fluctuation threshold and humidity deviation threshold corresponding to the target operating mode.

[0014] The target area identification module is used to identify the target area in the converter valve hall when the humidity deviation of a preset number of monitoring points meets the preset deviation conditions. The target area refers to the over-humidified or over-dry area that needs to be humidified.

[0015] The coupling strength calculation module is used to compare the return air temperature change rate with the temperature fluctuation threshold to obtain the real-time temperature deviation amplitude, and to calculate the coupling strength between temperature and humidity based on the real-time temperature deviation amplitude and the humidity deviation threshold.

[0016] The air conditioning switching command generation module is used to generate control mode switching commands for the air conditioning system based on the deviation acceleration of the return air temperature from the set temperature, the coupling strength of temperature and humidity, and the environmental uniformity of the valve hall characterized by the target area.

[0017] According to a third aspect, the present invention provides an electronic device comprising: At least one processor; and a memory communicatively connected to the at least one processor; The memory stores instructions that can be executed by the at least one processor, which are executed by the at least one processor to enable the at least one processor to execute any of the converter valve hall air conditioning system control methods in the embodiments of the present invention.

[0018] According to another aspect of the present invention, a non-transitory computer-readable storage medium storing computer instructions is provided, wherein the computer instructions are used to cause a computer to execute any of the converter valve hall air conditioning system control methods in the embodiments of the present invention.

[0019] The present invention provides a control method for an air conditioning system in a converter valve hall. This method is achieved through six core steps: temperature sequence acquisition, valve hall operating parameter calculation, target operating mode determination, target area identification, temperature and humidity coupling strength calculation, and control command generation. The system acquires the return air temperature sequence and outdoor ambient temperature sequence within the converter valve hall for real-time monitoring of the internal and external environmental conditions. Based on these sequences, valve hall operating parameters are calculated to quantify the contribution of natural cooling sources. When the proportion of cooling source contribution exceeds a preset threshold, a target operating mode is determined based on the comparison between the return air temperature sequence and the outdoor ambient temperature sequence, and corresponding temperature fluctuation and humidity deviation thresholds are generated for adaptive mode switching and threshold setting. When the humidity deviation at a preset number of monitoring points meets a preset deviation condition, a target area is identified within the converter valve hall to locate areas requiring priority humidity control. The return air temperature change rate is compared with the temperature fluctuation threshold to obtain the real-time temperature deviation amplitude, and the coupling strength between temperature and humidity is calculated based on the real-time temperature deviation amplitude and the humidity deviation threshold to quantify the interaction between temperature and humidity. Based on the acceleration of the return air temperature continuously deviating from the set temperature, the coupling strength between temperature and humidity, and the environmental equilibrium within the valve hall characterized by the target area, a control mode switching command for the air conditioning system is generated to achieve precise closed-loop control.

[0020] In the overall technical solution, this invention addresses the problem of low utilization efficiency of natural cold sources as described in the background technology. By calculating the contribution ratio of the cold source and triggering a dynamic determination mechanism for the target operating mode based on the comparison between return air temperature and outdoor ambient temperature when the ratio exceeds a preset threshold, it realizes the assessment of the contribution of outdoor natural cold sources and adaptive mode switching, thereby maximizing the utilization of natural cold sources for cooling. This solves the defect of natural cold source waste caused by the inability of the fixed cooling / heating mode switching logic of existing technologies to adapt to the cooling demand of flexible direct-flow valve halls in winter or transitional seasons. Regarding the problem of high system energy consumption, after meeting the above conditions, it generates temperature fluctuation thresholds and humidity deviation thresholds corresponding to the target operating mode, and calculates the coupling strength of temperature and humidity accordingly. This achieves refined and coordinated adjustment of the air conditioning system's operating status, avoiding redundant start-stop or over-operation of the mechanical refrigeration unit, and solving the drawback of high energy consumption in high heat load scenarios such as flexible direct-flow valve halls. Therefore, the technical solution of the present invention solves the technical problem of low utilization efficiency of natural cold source in existing air conditioning control methods in high heat load environments such as flexible DC converter valve halls, and improves the energy efficiency and operating economy of air conditioning systems.

Detailed Implementation

[0022] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of the present invention, including various details to aid understanding. These details should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope of the invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0023] During the development of this invention, researchers conducted numerous experiments and data analysis, revealing the intrinsic relationship between the outdoor ambient temperature sequence and the return air temperature sequence: when the outdoor ambient temperature decreases, the cooling potential of the natural cold source significantly increases, while the dynamic changes in return air temperature directly affect the heat load distribution within the valve hall and the energy consumption of the air conditioning system. Based on this relationship, this invention innovatively proposes this technical solution, utilizing real-time temperature data collected by multiple sensors to calculate valve hall operating parameters (such as the return air temperature change rate and the proportion of cold source contribution). When the proportion of cold source contribution exceeds a preset threshold, the system intelligently determines the target operating mode and generates corresponding control thresholds, thereby maximizing the energy efficiency and operational stability of the air conditioning system, embodying the core concept of intelligent decision-making based on multi-parameter dynamic coupling.

[0024] Specifically, through comparative experiments, the invention team discovered that the control method of traditional air-cooled heat pump refrigeration units with single-pass return air air handling units suffers from technical defects such as a single mode and low efficiency in utilizing natural cold sources: it relies solely on fixed cooling or heating modes and cannot dynamically adjust operating strategies according to outdoor climate conditions. These technical defects lead to persistently high air conditioning energy consumption in high-heat-load scenarios such as flexible direct-flow valve halls, and it cannot effectively utilize low-temperature outdoor air for natural cooling in winter or transitional seasons. However, the control method for air conditioning systems in converter valve halls proposed in this invention calculates the key parameter of the cold source contribution ratio and, when it exceeds a preset threshold, triggers a dynamic determination and threshold generation mechanism for the target operating mode based on the comparison of return air and outdoor temperatures. This achieves intelligent optimization of the cooling mode and efficient utilization of natural cold sources. By responding to preset humidity deviation conditions to identify target areas requiring humidity adjustment (overly humid or overly dry areas), and combining the calculated coupling strength between temperature and humidity, it ensures the synergy and spatial balance of temperature and humidity control. Finally, based on temperature deviation acceleration, the aforementioned coupling strength, and environmental balance, control commands are generated, achieving efficient, stable, and balanced operation of the system under different operating conditions. Therefore, this invention provides a control method for an air conditioning system in a converter valve hall, applicable to such systems (hereinafter referred to as "the system"). This system can operate in the converter valve hall through automatic control or manual intervention to stably maintain the temperature environment within the hall and reduce energy consumption of the air conditioning system. Specifically, this system can be deployed in various hardware environments, including but not limited to: a main controller, a temperature gradient acquisition unit, multiple temperature sensors (such as return air temperature sensors and outdoor ambient temperature sensors), and actuators (such as water pumps, heat pump chillers, fans, and heaters). This flexible deployment architecture allows the system to meet the high reliability requirements of high heat load scenarios in converter valve halls while adapting to dynamic switching between different climatic conditions and operating modes (such as normal mode and maintenance mode).

[0025] like Figure 1 As shown, the method may include: Step S110: Obtain the return air temperature sequence in the converter valve hall and the outdoor ambient temperature sequence.

[0026] The return air temperature sequence refers to the sequence of indoor return air temperature data collected by temperature and humidity sensors deployed at the return air inlet of the converter valve hall in chronological order; the outdoor ambient temperature sequence refers to the sequence of outdoor air temperature data collected by temperature and humidity sensors deployed outdoors in chronological order.

[0027] Specifically, the system can connect multiple temperature and humidity sensors (such as temperature and humidity sensor 1 for return air measurement and temperature and humidity sensor 3 for outdoor measurement) through a central controller to synchronously collect temperature and humidity data at a sampling frequency of once per second and store them in a time series format.

[0028] In other embodiments, the system can also synchronously collect the return air humidity sequence through the aforementioned temperature and humidity sensors. The return air humidity sequence refers to the sequence of indoor return air relative humidity data at the return air vent of the converter valve hall in chronological order.

[0029] For example, in normal operating mode, the system continuously collects return air temperature sequences (e.g., data points: (Unit: °C), outdoor ambient temperature series (e.g., data points: (unit: °C) and return air humidity series (e.g., data points: (Unit: %), sampling interval is 1 second, data length is 60 minutes, used for subsequent analysis.

[0030] Step S120: Calculate the valve hall operating parameters based on the return air temperature sequence and the outdoor ambient temperature sequence.

[0031] Among them, the valve hall operating parameters include the return air temperature change rate and the cold source contribution ratio. The return air temperature change rate refers to the amount of change in return air temperature per unit time, which is used to quantify the dynamic fluctuation characteristics of return air temperature. The cold source contribution ratio refers to the proportion of cooling capacity provided by natural cold source (outdoor low temperature air) to the total cooling demand, which is calculated by comparing the relationship between outdoor and return air temperatures.

[0032] Specifically, the system can calculate the rate of change of return air temperature by dividing the difference in return air temperature between adjacent time points by the sampling interval (formula: rate of change). ,in Return air temperature, (Sampling interval), and the contribution of the cold source is estimated by the ratio of the difference between the outdoor temperature and the return air temperature to the deviation between the return air temperature and the set lower limit (formula: ,in Outdoor temperature (Lower limit of temperature: 10°C).

[0033] For example, the system calculates the rate of change of return air temperature based on a 60-second return air temperature sequence (rising from 28.5°C to 29.0°C). When the return air temperature Outdoor temperature Set a lower limit At that time, the contribution of the cold source was 10%. .

[0034] Step S130: In response to the cold source contribution ratio exceeding the preset ratio threshold, the target operating mode is determined based on the comparison between the return air temperature sequence and the outdoor ambient temperature sequence, and the temperature fluctuation threshold and humidity deviation threshold corresponding to the target operating mode are generated.

[0035] Among them, the preset percentage threshold refers to the critical value of the cold source contribution percentage that triggers the mode switching (such as 50%); the target operating mode includes full host cooling mode, partial host cooling and natural cooling hybrid mode, etc.; the temperature fluctuation threshold refers to the upper limit of the allowable temperature deviation range; the humidity deviation threshold refers to the upper limit of the allowable humidity deviation range.

[0036] Specifically, the system can compare the contribution percentage of the cold source with a preset threshold (such as 50%). When the percentage exceeds the threshold, it will determine the appropriate action based on the return air temperature. With outdoor temperature Relationship selection patterns (such as when) and At that time, it was determined to be a hybrid mode of partial main unit cooling and natural cooling), and a temperature fluctuation threshold was set for this mode (e.g., ) and humidity deviation threshold (e.g. ).

[0037] For example, when the contribution of the cold source is 73.7%, exceeding the 50% threshold, and , (Assuming) The system determines the target operating mode as a hybrid mode of partial host cooling and natural cooling, and generates a temperature fluctuation threshold of 25°C and a humidity deviation threshold of 50%.

[0038] In some other embodiments, the system may also perform step S135 between step S130 above and step S140 below: calculate the humidity spatial gradient based on the comparison result between the current humidity distribution in the converter valve hall and the set humidity reference range.

[0039] Among them, the humidity spatial gradient refers to the rate of change of humidity data at different monitoring points within the converter valve hall over a unit distance, used to assess the uniformity of humidity distribution; the set humidity reference range refers to the allowable upper and lower limits of humidity (e.g., ...). to ).

[0040] Specifically, the system can acquire real-time humidity data at different locations within the valve chamber using multiple temperature and humidity sensors (such as sensors 1, 2, 4, and 5), and calculate the ratio of the humidity difference between adjacent sensors to their distance (formula: gradient). ,in (where is the sensor spacing), and the average value is taken as the overall humidity spatial gradient.

[0041] For example, based on sensor 1 (humidity 45%) and sensor 2 (humidity 47%), with a spacing of 10 meters, the system calculates the local humidity gradient as 0.2% / m (percentage per meter); the average humidity spatial gradient in the valve hall is 0.15% / m.

[0042] Step S140: In response to the occurrence of a preset number of monitoring points where the humidity deviation meets the preset deviation condition, the target area is identified in the converter valve hall.

[0043] Among them, the target area refers to the overly humid or overly dry area that needs to be humidified; the preset number of monitoring points refers to the minimum number of abnormal points that trigger the area identification (e.g., 2); the humidity deviation degree refers to the absolute difference between the real-time humidity of the monitoring point and the set benchmark median; the preset deviation condition refers to the deviation exceeding the allowable range (e.g., exceeding ±5%).

[0044] Specifically, the system can traverse all humidity data points and calculate the deviation from the set benchmark median (e.g., 32.5%). When the deviation of multiple consecutive points exceeds ±5%, the area is marked as the target area.

[0045] For example, the system detected that the deviations of sensor 4 (humidity 50%) and sensor 5 (humidity 52%) both exceeded +5%, and they were spatially adjacent. Therefore, the system identified this area as an over-humidified target area, and dehumidification adjustment should be prioritized.

[0046] Step S150: Compare the return air temperature change rate with the temperature fluctuation threshold to obtain the real-time temperature deviation amplitude, and calculate the coupling strength between temperature and humidity based on the real-time temperature deviation amplitude and the humidity deviation threshold.

[0047] Among them, the real-time temperature deviation amplitude refers to the ratio of the return air temperature change rate to the temperature fluctuation threshold; the coupling strength refers to the degree of correlation between temperature and humidity changes, which is quantified by a weighted combination of the deviation amplitude and the humidity deviation threshold.

[0048] Specifically, the system can calculate the real-time state using the following formula (e.g., if the rate of change is 0.0083°C / s and the threshold is 25°C, then the amplitude is 0.000332): ; The coupling strength is then calculated using the following formula: ; in , These are weighting coefficients, such as all of them being 0.5.

[0049] For example, when the real-time temperature deviation is 0.000332 and the humidity deviation is 5% (threshold 50%), the calculated coupling strength is 0.250166.

[0050] Step S160: Based on the deviation acceleration of the return air temperature from the set temperature, the coupling strength of temperature and humidity, and the environmental uniformity in the valve hall characterized by the target area, generate the control mode switching command for the air conditioning system.

[0051] Among them, deviation acceleration refers to the rate of change of return air temperature deviation over time; environmental uniformity refers to the proportion of the target area to the total area of ​​the valve hall, used to assess environmental uniformity.

[0052] Specifically, the system can obtain the acceleration by calculating the change in the deviation amplitude over consecutive time intervals (formula: In conjunction with coupling strength and balance (e.g., the target area accounts for 20%), when the acceleration exceeds the threshold (e.g., 0.001) and the coupling strength is high, a command is generated to switch to a more efficient mode (e.g., switch from natural cooling mode to hybrid mode).

[0053] For example, when the deviation acceleration is 0.0005, the coupling strength is 0.25, and the balance is 20%, the system generates a command to start water pump 1 and heat pump cooling host, switching to a hybrid mode of partial host cooling and natural cooling.

[0054] In other embodiments, such as Figure 2 The diagram shows the temperature and humidity monitoring and control process of the air conditioning system in the converter valve hall. It specifically illustrates the physical sensor layout and air handling path deployed to implement the aforementioned control method. The system uses five temperature and humidity acquisition devices (labeled as...). to Real-time monitoring of key nodes throughout the entire air handling process. Temperature and humidity acquisition device. Deployed at the return air vent of the valve hall, it continuously monitors the return air temperature and humidity sequences, sampling once per second. Data is uploaded to the main controller via fieldbus (e.g., RS-485). Temperature and humidity acquisition devices are deployed at the fresh air inlet. This is used to acquire outdoor ambient temperature and humidity data. After the return air undergoes pre-cooling treatment through a natural cooling module (such as an air-side heat exchanger), its state is determined by the device. Monitoring. Subsequently, a portion of the treated return air mixes with the fresh air to form mixed air. After further temperature and humidity regulation by flowing through the air conditioning surface cooling (heating) coils, the state of the mixed air is determined by the device. Monitoring. Finally, the supplied air, after passing through the electric heater, humidifier, and fan, is sent into the valve hall, where its final temperature and humidity status is determined by the device. Conduct confirmatory monitoring to form " The distributed monitoring network provides a comprehensive and synchronous data source for calculating the return air temperature change rate, the proportion of cold source contribution, the humidity spatial gradient, and identifying target areas. This is the foundation for achieving precise mode switching and threshold control. For example, the device... Collected return air temperature series (unit: ) and apparatus Collected outdoor ambient temperature series (unit: It is directly used to calculate the efficiency of natural cooling sources and to determine whether a mode switch is triggered.

[0055] In other embodiments, such as Figure 3 The diagram shows the control logic architecture and execution linkage of the air conditioning system in the converter valve hall. The temperature sensor (1) is used to monitor the water supply temperature of the heat pump chiller (8) (unit: ...). ), providing key parameters for the operating status of the refrigeration system. Temperature and humidity sensor 1 (2) is deployed at the return air inlet to measure the temperature of the return air (unit: ) and relative humidity (unit: The temperature and humidity sensor 2 (3) is located after the pre-cooling heat exchanger and monitors the temperature and humidity of the return air after natural cooling to evaluate the effect of natural cooling. The temperature and humidity sensor 3 (4) is installed at the fresh air inlet and collects the outdoor ambient temperature and humidity sequence to provide input for judging the availability of natural cold source. The temperature and humidity sensor 4 (5) is set after the air conditioning surface cooling (heating) coil and detects the temperature and humidity after mixed air treatment to verify the regulation effect of surface cooling coil. The temperature and humidity sensor 5 (6) is located at the end of the air supply duct and monitors the final air supply parameters to ensure that the air supply status meets the set range. In the execution equipment, water pump 1 (7) and heat pump refrigeration unit (8) work together to regulate the cooling and heating of the air conditioning surface cooling (heating) coil; fan 1 (9) and water pump 2 (10) jointly control the natural cooling of the pre-cooling heat exchanger, and achieve fine control of the cooling capacity by adjusting the frequency; heater (11) supplements heat in the winter heating mode; humidifier (12) humidifies the air when the humidity is insufficient; fan 2 (13) is responsible for driving the air flow to ensure the air volume. The main controller (14) is the core processing unit, which integrates all sensor data, executes the control logic described in this invention, generates mode switching instructions and coordinates the actions of each execution device to achieve adaptive operation of the system.

[0056] Furthermore, Figure 3The closed-loop control system architecture, consisting of a temperature and humidity acquisition network (components 1-6), a main controller (rectangular frame 14), and an array of execution devices (components 7-13), is specifically demonstrated through functional modules and physical connections. This architecture is used to realize the multi-parameter intelligent decision-making and mode switching functions described in this invention. The temperature and humidity acquisition network consists of five temperature and humidity sensors (components 1-5, labeled TH) and one temperature sensor (component 6, labeled T). These sensors are deployed at key nodes such as return air, fresh air, and mixed air, and are used to synchronously collect raw data such as return air temperature sequence, outdoor ambient temperature sequence, and return air humidity sequence. The data is then reported to the main controller (14) in real time via communication lines (as shown by solid lines). The main controller (14) runs the control method of this invention. Its core includes logic modules such as a rate of change calculation unit, an efficiency analysis unit, a mode determination unit, and a threshold generation unit, which are used to complete parameter calculation, mode judgment, and command generation. Based on the generated control mode switching command, the main controller (14) drives the execution device array below to coordinate its actions via control lines (as shown by dashed lines). The array includes, but is not limited to, water pumps (components 7 and 10), heat pump refrigeration units (component 8), fans (component 9), electric heaters (component 11), and humidifiers (components 12 and 13). These devices, according to different combinations of instructions (such as turning on specific water pumps and units, or adjusting the fan frequency), precisely achieve target sub-operation modes such as full main unit cooling mode, partial main unit cooling and natural cooling mixed mode, in order to regulate the temperature and humidity of the supplied air. For example, when the system determines that it needs to enter the partial main unit cooling and natural cooling mixed mode, the main controller (14) will simultaneously issue start / stop or adjustment instructions to component 7 (water pump 1), component 8 (heat pump refrigeration unit), component 9 (fan), and component 12 (humidifier), forming a physical control closed loop that is dynamically adjusted according to real-time data.

[0057] Therefore, according to the above implementation method, the system achieves its purpose through six core steps: temperature sequence acquisition, valve hall operating parameter calculation, target operating mode determination, target area identification, temperature and humidity coupling strength calculation, and control command generation. The system acquires the return air temperature sequence and outdoor ambient temperature sequence within the converter valve hall for real-time monitoring of the internal and external environmental conditions. Based on these sequences, valve hall operating parameters are calculated to quantify the contribution of natural cooling sources. When the proportion of cooling source contribution exceeds a preset threshold, a target operating mode is determined based on the comparison between the return air temperature sequence and the outdoor ambient temperature sequence, and corresponding temperature fluctuation and humidity deviation thresholds are generated for adaptive mode switching and threshold setting. When the humidity deviation at a preset number of monitoring points meets a preset deviation condition, a target area is identified within the converter valve hall to locate areas requiring priority humidity control. The return air temperature change rate is compared with the temperature fluctuation threshold to obtain the real-time temperature deviation amplitude, and the coupling strength between temperature and humidity is calculated based on the real-time temperature deviation amplitude and the humidity deviation threshold to quantify the interaction between temperature and humidity. Based on the acceleration of the return air temperature continuously deviating from the set temperature, the coupling strength between temperature and humidity, and the environmental equilibrium within the valve hall characterized by the target area, a control mode switching command for the air conditioning system is generated to achieve precise closed-loop control.

[0058] Specifically, in this implementation, addressing the problem of low utilization efficiency of natural cold sources mentioned in the background technology, a dynamic determination mechanism for the target operating mode based on the comparison between return air temperature and outdoor ambient temperature is triggered when the contribution ratio of the cold source is calculated and exceeds a preset threshold. This achieves the assessment of the contribution of outdoor natural cold sources and adaptive mode switching, thereby maximizing the utilization of natural cold sources for cooling. This solves the defect of natural cold source waste caused by the inability of the fixed cooling / heating mode switching logic of existing technologies to adapt to the cooling demand of flexible direct-flow valve halls in winter or transitional seasons. Regarding the problem of high system energy consumption, after meeting the above conditions, a temperature fluctuation threshold and humidity deviation threshold corresponding to the target operating mode are generated, and the coupling strength of temperature and humidity is calculated accordingly. This achieves refined and coordinated adjustment of the air conditioning system's operating status, avoiding redundant start-stop or over-operation of the mechanical refrigeration unit, and solving the drawback of high energy consumption in high heat load scenarios such as flexible direct-flow valve halls. Therefore, the technical solution of the present invention solves the technical problem of low utilization efficiency of natural cold source in existing air conditioning control methods in high heat load environments such as flexible DC converter valve halls, and improves the energy efficiency and operating economy of air conditioning systems.

[0059] In some embodiments, the return air temperature sequence and the outdoor ambient temperature sequence are obtained by a temperature gradient collector configured in the converter valve hall. The valve hall operating parameters also include the outdoor temperature change rate and the natural cooling source efficiency. The valve hall operating parameters are calculated based on the return air temperature sequence and the outdoor ambient temperature sequence, including: Based on the return air temperature sequence, the rate of change calculation unit configured by the temperature gradient collector calculates the first temperature difference between adjacent time intervals, and determines the return air temperature change rate based on the ratio of the first temperature difference to the time interval.

[0060] The rate of change calculation unit refers to the dedicated processing module inside the temperature gradient collector used to calculate the rate of temperature change; the return air temperature change rate refers to the amount of change in return air temperature per unit time, used to quantify the dynamic fluctuation characteristics of return air temperature.

[0061] Specifically, the system can read continuous data points in the return air temperature sequence at a fixed sampling interval (e.g., 1 second) through the rate of change calculation unit, calculate the first temperature difference between adjacent time points, divide the difference by the sampling interval to obtain the instantaneous rate of change, and then average multiple instantaneous values ​​to improve stability.

[0062] For example, the system is based on return air temperature sequence data points (unit: The sampling interval is 1 second, and the calculated sequence of differences between adjacent points is as follows: (unit: The return air temperature change rate is s.

[0063] Based on the outdoor ambient temperature sequence, the second temperature difference between adjacent time intervals is calculated by the rate of change calculation unit, and the outdoor temperature change rate is determined based on the ratio of the second temperature difference to the time interval.

[0064] Among them, the outdoor temperature change rate refers to the change in outdoor ambient temperature per unit time, which is used to reflect the dynamic characteristics of outdoor climate conditions.

[0065] Specifically, the system uses the same calculation logic as the return air temperature change rate, processes the outdoor ambient temperature sequence through the change rate calculation unit, and introduces a sliding window mechanism (such as a 10-second window) to smooth random fluctuations.

[0066] For example, outdoor ambient temperature series data points are (unit: The sampling interval is 1 second, and the difference sequence is as follows: (unit: The outdoor temperature change rate is: .

[0069] Specifically, the system uses an efficiency analysis unit to divide the return air temperature change rate (absolute value to avoid negative values) by the outdoor temperature change rate (absolute value), and then multiplies by 100 to convert it into a percentage form. The formula is as follows: For example, when the return air temperature change rate is... Outdoor temperature change rate hour, This indicates that the cooling efficiency of natural cold sources is higher than the indoor temperature fluctuation requirements.

[0070] The proportion of the cold source contribution is obtained by calculating the proportion of the temperature change of a single monitoring point to the total temperature change of all monitoring points through the efficiency analysis unit.

[0071] Among them, the cold source contribution ratio refers to the relative contribution of the area represented by a single monitoring point to the total cooling demand, which is used to locate key heat source areas.

[0072] Specifically, the system first calculates the absolute value of the temperature change at each monitoring point within a specified time period (e.g., 10 minutes), sums these values ​​to obtain the total change, and then calculates the ratio of the change at a single monitoring point to the total change. For example, the temperature changes at three monitoring points in the valve hall are as follows: The total change is The contribution percentages of the cold source at the three points are as follows: .

[0073] Therefore, according to the above implementation method, the system can accurately quantify the efficiency of natural cold sources and the distribution of local heat load through multi-parameter collaborative calculation, providing a data basis for subsequent adaptive mode switching.

[0074] In some embodiments, the target operating mode includes a normal operating mode and a maintenance operating mode; the steps of determining the target operating mode based on the comparison between the return air temperature sequence and the outdoor ambient temperature sequence, and generating a temperature fluctuation threshold and a humidity deviation threshold corresponding to the target operating mode, include: The mode selection signal characterizing the valve hall's operating state is acquired through the mode determination unit configured by the temperature gradient acquisition device.

For example, when At that time, because and The system determines the target sub-operation mode as fresh air dehumidification mode.

[0084] The threshold generation unit configured by the temperature gradient collector obtains the corresponding temperature fluctuation threshold and humidity deviation threshold from the preset threshold mapping according to the target sub-operation mode corresponding to the determined normal operation mode or maintenance operation mode.

[0086] Specifically, the system queries the threshold mapping table through the threshold generation unit and reads the preset threshold according to the target sub-operation mode: for example, for the full host cooling mode, the temperature fluctuation threshold is set to The humidity deviation threshold is set to For some main unit cooling and natural cooling hybrid modes, the temperature fluctuation threshold is set to... The humidity deviation threshold is set to For example, when the target sub-operation mode is a hybrid mode of partial host cooling and natural cooling, the system reads the temperature fluctuation threshold from the threshold mapping. Set the humidity deviation threshold to 50% and assign it as the current effective threshold.

[0087] Therefore, according to the above implementation method, the system can intelligently switch modes according to the valve hall operating status and dynamically generate suitable temperature and humidity control thresholds, thereby improving the adaptability and energy efficiency of the air conditioning system.

[0088] In some embodiments, the multiple target sub-operation modes of the normal operation mode include a fully automatic cooling mode, a hybrid mode of partial automatic cooling and natural cooling, a fully natural cooling mode, a ventilation mode, and a heating mode; if the normal operation mode is determined, the step of obtaining the corresponding temperature fluctuation threshold and humidity deviation threshold from a preset threshold mapping includes: The threshold generation unit reads the corresponding upper limit values ​​of temperature fluctuation threshold and humidity deviation threshold from the preset threshold mapping table according to the specific type of the target sub-operation mode.

For example, when the target sub-operation mode is a hybrid mode of partial host cooling and natural cooling, the system reads the upper limit of the temperature fluctuation threshold from the threshold mapping table. (based on calculate, The upper limit of the humidity deviation threshold is 50% (based on...). calculate, ).

[0091] If the target sub-operation mode is a full host cooling mode or a mixed mode of partial host cooling and natural cooling, then the first temperature fluctuation threshold and the first humidity deviation threshold corresponding to the mechanical cooling condition are read from the threshold mapping table and used as the upper limit values ​​of the temperature fluctuation threshold and the humidity deviation threshold.

[0093] Specifically, the system identifies the target sub-operating mode as mechanically refrigerated dominant through a threshold generation unit, and reads the first temperature fluctuation threshold and the first humidity deviation threshold from the "Mechanical Refrigeration Condition" category in the threshold mapping table. For example, for a fully host-cooled mode, the first temperature fluctuation threshold is set to... ( The first humidity deviation threshold is set to 50%. ),in This is the upper limit of the temperature in normal mode. This represents the upper limit of humidity.

[0094] Alternatively, if the target sub-operation mode is a completely natural cooling mode or a ventilation mode, then the second temperature fluctuation threshold and the second humidity deviation threshold corresponding to the natural cold source operating condition are read from the threshold mapping table and used as the upper limit values ​​of the temperature fluctuation threshold and the humidity deviation threshold.

[0096] Specifically, the system uses a threshold generation unit to determine whether the target sub-operation mode relies on a natural cooling source. It then reads the second temperature fluctuation threshold and the second humidity deviation threshold from the "Natural Cooling Source Condition" category in the threshold mapping table. These thresholds are typically set more leniently to prioritize energy efficiency. For example, for a completely natural cooling mode, the second temperature fluctuation threshold is set to... The second humidity deviation threshold is set to 52% ( This allows for a wider range of temperature and humidity fluctuations, maximizing the use of natural cooling sources.

[0097] Alternatively, if the target sub-operation mode is heating mode, then the third temperature fluctuation threshold and the third humidity deviation threshold corresponding to the heating condition are read from the threshold mapping table and used as the upper limit values ​​of the temperature fluctuation threshold and the humidity deviation threshold.

[0098] Among them, the heating condition refers to the operating state in which the valve hall temperature is maintained by heating through a heater or heat pump; the third temperature fluctuation threshold refers to the upper limit of the temperature fluctuation threshold specifically for the heating condition (unit: The third humidity deviation threshold refers to the upper limit of the humidity deviation threshold specifically for heating conditions (unit: ).

[0099] Specifically, the system identifies the target sub-operation mode as heating mode through the threshold generation unit, and reads the third temperature fluctuation threshold and the third humidity deviation threshold from the "heating condition" category of the threshold mapping table. These thresholds focus on preventing overheating and excessively low humidity.

[0100] For example, for heating mode, the third temperature fluctuation threshold is set to The third humidity deviation threshold is set to 45%. This is to ensure that the temperature inside the valve hall does not fall below the lower limit and that the humidity is controllable.

[0101] The threshold generation unit assigns the upper limit values ​​of the temperature fluctuation threshold and the upper limit values ​​of the humidity deviation threshold to the effective temperature fluctuation threshold and the effective humidity deviation threshold within the current control cycle, respectively.

[0102] Among them, the current control cycle refers to the time interval (e.g., 60 seconds) during which the system executes control logic; the effective temperature fluctuation threshold refers to the actual temperature fluctuation threshold used for comparison within the current cycle; and the effective humidity deviation threshold refers to the actual humidity deviation threshold used for comparison within the current cycle.

For example, the system will assign the read upper threshold value of temperature fluctuation to a global variable or register. The effective temperature fluctuation threshold is assigned, and 50% of the upper limit of the humidity deviation threshold is assigned as the effective humidity deviation threshold. These values ​​are used continuously for temperature and humidity deviation judgment within the current 60-second control cycle.

[0104] Therefore, according to the above implementation method, the system can dynamically adjust the temperature and humidity control threshold according to the specific sub-mode under the normal operating mode, so as to achieve precise adaptive adjustment and improve energy efficiency and stability.

[0105] In some embodiments, the multiple target sub-operation modes of the maintenance operation mode include a cooling mode, a fresh air dehumidification mode, a ventilation mode, and a heating mode; if the maintenance operation mode is determined, the step of obtaining the corresponding temperature fluctuation threshold and humidity deviation threshold from a preset threshold mapping includes: The threshold generation unit reads the corresponding upper limit values ​​of temperature fluctuation threshold and humidity deviation threshold from the preset threshold mapping table according to the specific type of the target sub-operation mode.

[0106] The threshold generation unit refers to a dedicated calculation module within the temperature gradient collector used to dynamically generate control thresholds; the preset threshold mapping table refers to a data structure pre-stored in memory, recording the correspondence between each sub-operation mode and the threshold in key-value pairs; the upper limit of the temperature fluctuation threshold refers to the upper limit of the allowed temperature deviation range (unit: ), used to control temperature fluctuations; the upper limit of the humidity deviation threshold refers to the upper limit of the allowable humidity deviation range (unit: ), used to control humidity deviation.

[0107] Specifically, the system queries a preset threshold mapping table through the threshold generation unit, and retrieves the corresponding upper limit of temperature fluctuation threshold and upper limit of humidity deviation threshold as values ​​based on the enumerated value (such as mode code or name) of the target sub-operation mode as the key.

[0108] For example, when the target sub-operation mode is fresh air dehumidification mode, the system reads the upper limit of the temperature fluctuation threshold from the threshold mapping table. (Based on the upper limit of the maintenance mode temperature) calculate, The upper limit of the humidity deviation threshold is (Based on humidity limit) %calculate, ).

[0109] If the target sub-operation mode is cooling mode or fresh air dehumidification mode, then the fourth temperature fluctuation threshold and the fourth humidity deviation threshold corresponding to the cooling and dehumidification conditions are read from the threshold mapping table and used as the upper limit values ​​of the temperature fluctuation threshold and the humidity deviation threshold.

[0110] Among them, the cooling and dehumidification mode refers to the operating state that relies on the heat pump refrigeration unit for cooling and dehumidification; the fourth temperature fluctuation threshold refers to the upper limit of the temperature fluctuation threshold specifically for the cooling and dehumidification mode (unit: The fourth humidity deviation threshold refers to the upper limit of the humidity deviation threshold specifically for refrigeration and dehumidification operation (unit: ).

[0111] Specifically, the system identifies the target sub-operation mode as either cooling or dehumidification dominant through the threshold generation unit, and reads the fourth temperature fluctuation threshold and the fourth humidity deviation threshold from the "cooling and dehumidification condition" category in the threshold mapping table. These thresholds focus on rapid cooling and humidity control.

[0112] For example, in cooling mode, the fourth temperature fluctuation threshold is set to... ( , The fourth humidity deviation threshold is set to ( , %), to ensure that temperature and humidity fluctuations are within a safe range during maintenance.

[0113] Alternatively, if the target sub-operation mode is ventilation mode, the fifth temperature fluctuation threshold and the fifth humidity deviation threshold corresponding to the ventilation condition are read from the threshold mapping table and used as the upper limit values ​​of the temperature fluctuation threshold and the humidity deviation threshold.

[0114] Among them, ventilation mode refers to the operating state that mainly utilizes outdoor air for air exchange; the fifth temperature fluctuation threshold refers to the upper limit of the temperature fluctuation threshold specifically for ventilation mode (unit: The fifth humidity deviation threshold refers to the upper limit of the humidity deviation threshold specifically for ventilation conditions (unit: ).

These thresholds are set relatively leniently to prioritize energy efficiency.

[0116] For example, for ventilation mode, the fifth temperature fluctuation threshold is set to... ( 8, The fifth humidity deviation threshold is set to ( , (%), to allow for greater temperature and humidity fluctuations and to make full use of outdoor conditions.

[0117] Alternatively, if the target sub-operation mode is heating mode, then the sixth temperature fluctuation threshold and the sixth humidity deviation threshold corresponding to the heating condition are read from the threshold mapping table and used as the upper limit values ​​of the temperature fluctuation threshold and the humidity deviation threshold.

[0118] Among them, heating mode refers to the operating state in which the valve hall temperature is maintained by heating through heaters or heat pumps; the sixth temperature fluctuation threshold refers to the upper limit of the temperature fluctuation threshold specifically for heating mode (unit: The sixth humidity deviation threshold refers to the upper limit of the humidity deviation threshold specifically for heating conditions (unit: %).

[0119] Specifically, the system identifies the target sub-operation mode as heating mode through the threshold generation unit, and reads the sixth temperature fluctuation threshold and the sixth humidity deviation threshold from the "Heating Condition" category of the threshold mapping table. These thresholds focus on preventing overheating and excessively low humidity.

[0120] For example, for heating mode, the sixth temperature fluctuation threshold is set to ( +2, =10 The sixth humidity deviation threshold is set to ( , This ensures that the temperature inside the valve chamber does not fall below the lower limit and that the humidity is controllable.

[0121] The threshold generation unit assigns the upper limit values ​​of the temperature fluctuation threshold and the upper limit values ​​of the humidity deviation threshold to the effective temperature fluctuation threshold and the effective humidity deviation threshold within the current control cycle, respectively.

[0122] Among them, the current control cycle refers to the time interval (in seconds) during which the system executes control logic; the effective temperature fluctuation threshold refers to the actual temperature fluctuation threshold used for comparison within the current cycle; and the effective humidity deviation threshold refers to the actual humidity deviation threshold used for comparison within the current cycle.

[0123] Specifically, the system uses a threshold generation unit to assign the read upper limit value of the threshold to a global variable or register, which serves as the effective threshold for the current control cycle and is used for subsequent real-time data comparison and decision-making.

[0124] For example, the system will read the upper limit of the temperature fluctuation threshold. Assign the effective temperature fluctuation threshold value, and set the upper limit value of the humidity deviation threshold value. The values ​​are assigned to the effective humidity deviation threshold, and these values ​​are continuously used to determine the temperature and humidity deviation within the current 60-second control cycle.

[0125] Therefore, according to the above implementation method, the system can dynamically adjust the temperature and humidity control threshold according to the specific sub-mode under the maintenance operation mode, so as to achieve precise adaptive adjustment and improve energy efficiency and stability.

[0126] In some embodiments, the preset deviation conditions include an over-humidity deviation condition and an over-dryness deviation condition; the over-humidity deviation condition refers to the deviation value of the real-time humidity data of the monitoring point exceeding the upper limit of the set humidity reference range, which exceeds a preset over-humidity threshold; the over-dryness deviation condition refers to the deviation value of the real-time humidity data of the monitoring point falling below the lower limit of the set humidity reference range, which exceeds a preset over-dryness threshold; the step of identifying the target area within the converter valve hall includes: Real-time humidity data from multiple monitoring points within the valve hall is obtained using a humidity analyzer.

[0127] Among them, the humidity analyzer refers to a special device deployed in the converter valve hall for collecting and processing humidity data, which has multi-channel data acquisition capabilities and communication interfaces; real-time humidity data refers to the relative humidity value (unit: %) read from the temperature and humidity sensor at a preset sampling frequency (such as once per second).

[0128] Specifically, the system can use the data acquisition module of the humidity analyzer to cyclically scan the sensor addresses of each monitoring point, in order to... (A serial communication protocol) The protocol reads the humidity register value and converts it into a floating-point number format, storing it in a buffer. For example, the system collects real-time humidity data from four monitoring points through a humidity analyzer: 45% for monitoring point 1, 47% for monitoring point 2, 44% for monitoring point 3, and 50% for monitoring point 4, with a sampling timestamp of 10:30:15 on January 24, 2025.

[0129] For each monitoring point, calculate the degree of deviation between the real-time humidity data of the monitoring point and the midpoint of the set humidity reference range.

[0130] Here, the set humidity reference range refers to the allowable upper and lower limits of humidity (lower limit) upper limit The formula for calculating its value is: Deviation refers to the absolute difference (in %) between real-time humidity data and the baseline median.

[0131] Specifically, the system uses the built-in computing unit of the humidity analyzer to calculate the humidity using the formula " "Calculate the deviation point by point, retaining one decimal place of precision. For example, when..." At that time, the baseline median was 32.5%; the deviation of the real-time humidity at monitoring point 1 from 45% was... The deviation of the real-time humidity at monitoring point 4 from 50% is... .

[0132] In response to deviations that meet either the excessively wet or excessively dry conditions, the corresponding monitoring point is marked as an anomaly.

[0133] Among them, the excessive humidity deviation condition refers to the deviation being greater than the preset excessive humidity threshold (e.g., 15%) and the real-time humidity being higher than the benchmark median; the excessive dryness deviation condition refers to the deviation being greater than the preset excessive dryness threshold (e.g., 20%) and the real-time humidity being lower than the benchmark median; and the abnormal point refers to the monitoring point marker where the humidity status exceeds the reasonable range.

[0134] Specifically, the system uses the logic judgment module of the humidity analyzer to sequentially check the degree of deviation and humidity direction of each monitoring point: if the degree of deviation... And real-time humidity Mark as an abnormally wet point; if the deviation is significant... And real-time humidity These are marked as excessively dry anomalies.

[0135] For example, the degree of deviation of monitoring point 4 And humidity Points with excessive humidity are marked as abnormal points; if the humidity at a certain monitoring point is... (degree of deviation) And humidity If the value is 0, it is marked as an overly dry anomaly.

[0136] Based on the spatial relationship of outliers, continuously distributed outlier regions are identified as target regions.

[0137] Among them, spatial location relationship refers to the coordinate correlation of abnormal points in the valve hall plan layout; continuous distribution means that the distance between abnormal points is less than the preset adjacency threshold (such as 15 meters) and forms a connected area; target area refers to the over-humidified or over-dry area that needs to be prioritized for humidification.

[0138] Specifically, the system uses the area analysis module of the humidity analyzer to calculate the Euclidean distance between all anomaly points. If the distance between adjacent points is less than 15 meters, they are merged into the same area, and the coordinates of the area boundary are recorded. For example, monitoring point 4 (coordinates...) rice, (meters) and monitoring point 5 (coordinates) rice, (meters) distance All of them are excessively humid abnormal points, and the system merges them into a rectangular target area with an area of ​​120 square meters (assuming the total area of ​​the valve hall is 600 square meters).

[0139] Therefore, according to the above implementation method, the system can accurately locate local over-humidified or over-dry areas by quantifying the degree of humidity deviation and spatial clustering analysis, providing a basis for targeted humidity control.

[0140] In some embodiments, the real-time temperature deviation is obtained by comparing the return air temperature change rate with a temperature fluctuation threshold, and the coupling strength between temperature and humidity is calculated based on the real-time temperature deviation and a humidity deviation threshold, including: The deviation calculation unit configured by the temperature gradient collector calculates the difference between the return air temperature change rate and the temperature fluctuation threshold, and determines the real-time temperature deviation based on the ratio of the difference to the temperature fluctuation threshold.

[0141] The deviation amplitude calculation unit refers to the dedicated algorithm module inside the temperature gradient collector used to calculate the degree of temperature deviation; the real-time temperature deviation amplitude refers to the normalized deviation value (unit: no unit) of the return air temperature change rate relative to the temperature fluctuation threshold, which is used to quantify the severity of temperature fluctuation.

[0142] Specifically, the system performs arithmetic operations through the deviation calculation unit: first, it calculates the return air temperature change rate (unit: ) and temperature fluctuation threshold (unit: The difference between the return air temperature and the temperature fluctuation threshold is then divided to obtain the real-time temperature deviation in the form of a ratio. For example, the return air temperature change rate is... Temperature fluctuation threshold is The difference is The ratio is The absolute value is taken as the real-time temperature deviation range of 0.99.

[0143] The coupled analysis unit configured with the temperature gradient acquisition device compares the real-time temperature deviation with the humidity deviation threshold.

[0144] The coupling analysis unit refers to the logic judgment module inside the temperature gradient collector used to evaluate the strength of the temperature-humidity correlation; the humidity deviation threshold refers to the upper limit of the allowable humidity deviation (unit: (), used to define the tolerance range for humidity control.

[0145] Specifically, the system reads the real-time temperature deviation magnitude (e.g., 0.99) and humidity deviation threshold (e.g., ...) through a coupled analysis unit. The two values ​​are compared to determine whether the temperature deviation exceeds the threshold associated with humidity control. For example, the coupled analysis unit compares a real-time temperature deviation of 0.99 with a humidity deviation threshold of 50% (converted to a decimal of 0.5). This triggers subsequent coupling strength grading logic.

[0146] In response to the real-time temperature deviation being less than the humidity deviation threshold, the coupling strength between temperature and humidity is determined as the first coupling strength.

[0147] The first coupling strength refers to the level of low temperature-humidity correlation, indicating that when temperature fluctuations are within the humidity tolerance range, the system can prioritize humidity stability.

[0148] Specifically, when the real-time temperature deviation (e.g., 0.3) is less than the humidity deviation threshold (e.g., 0.5), the coupling analysis unit outputs a first coupling strength flag (e.g., code value 1) to indicate a mild temperature and humidity interaction state. For example, if the real-time temperature deviation is 0.3 < the humidity deviation threshold of 0.5, the system determines the coupling strength as the first coupling strength and generates a flag bit Coupling_Level=1.

[0149] In response to a real-time temperature deviation that is greater than or equal to a humidity deviation threshold but less than a preset upper limit threshold, the coupling strength between temperature and humidity is determined as the second coupling strength.

[0150] The second coupling strength refers to a moderate level of temperature and humidity correlation, indicating that temperature fluctuations have reached the humidity tolerance boundary and require coordinated control; the preset upper limit threshold is the critical value (unit: no unit) that triggers high-intensity coupling, and is usually set as a multiple of the humidity deviation threshold (e.g., 2 times).

[0151] Specifically, when the real-time temperature deviation is greater than or equal to the humidity deviation threshold but less than the preset upper limit threshold (e.g., 1.0), the coupling analysis unit outputs a second coupling strength flag (e.g., code value 2). For example, if the real-time temperature deviation is 0.99 ≥ the humidity deviation threshold of 0.5 and < the preset upper limit threshold of 1.0, the system determines the coupling strength as the second coupling strength, and the flag Coupling_Level=2.

[0152] In response to a real-time temperature deviation that is greater than or equal to a preset upper limit threshold, the coupling strength between temperature and humidity is determined as the third coupling strength.

[0153] The third coupling strength refers to the level of high temperature-humidity correlation, indicating that temperature fluctuations severely exceed humidity tolerance and require emergency intervention.

[0154] Specifically, when the real-time temperature deviation is greater than or equal to a preset upper limit threshold (e.g., 1.0), the coupling analysis unit outputs a third coupling strength flag (e.g., code value 3). For example, if the real-time temperature deviation is 1.2 ≥ the preset upper limit threshold of 1.0, the system determines the coupling strength to be the third coupling strength, and the flag Coupling_Level = 3.

[0155] Therefore, according to the above implementation method, the system can dynamically assess the coupling strength by quantifying the temperature and humidity deviation relationship, providing a hierarchical decision basis for adaptive control.

[0160] The target area identification module 240 is used to identify the target area in the converter valve hall when the humidity deviation of a preset number of monitoring points meets the preset deviation conditions. The target area refers to the over-humidified or over-dry area that needs to be humidified.
