Description

Technical Field

[0001] This invention relates to the field of streaming computing technology, and in particular to a streaming computing engine system applicable to various scenarios. Background Technology

[0002] In industrial and IoT remote operation and maintenance, cellular communication equipment is often installed in highly sealed metal control cabinets, with radio frequency antennas typically connected to the cabinet via cables passing through metal plates. These devices operate under conditions of constant diurnal temperature variations, external rainfall or fog, and uneven ventilation in the equipment room. The temperature and humidity inside the cabinet fluctuate rapidly with workload and external weather. The high thermal conductivity channels formed by the metal plates and their contact points easily bring external cold air into the cabinet. When the surface temperature at these points is lower than the dew point of the air inside the cabinet, water films or droplets form on the radio frequency connectors and metal surfaces. These water films alter the electromagnetic boundary conditions at the ports, affecting the impedance matching and power transmission of the radio frequency link. This can range from causing increased VSWR and decreased throughput to triggering session re-establishment and service jitter, creating a chain reaction that impacts commands and telemetry within the maintenance window.

[0003] Current practices mainly rely on fixed threshold alarms, timed inspections, or judgments of exceeding limits of a single sensor value: one type of method only triggers maintenance based on abnormal standing waves or reflection coefficients, making it difficult to determine whether the abnormality originates from condensation; another type of method uses artificial heating or temporary heating elements, but lacks targeted calculations of target temperature and effective range, often resulting in excessive heating or delayed handling, which affects energy consumption and makes it difficult to eradicate the mismatch. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the lack of targeted calculation of target temperature and effective range, which often leads to excessive heating or delayed processing, affecting energy consumption and making it difficult to eliminate mismatches.

[0046] Compared with the prior art, the beneficial effects of the present invention are:

[0047] 1. In this invention, by performing dynamic data flow analysis on the characteristic impedance of the RF transmission line, the cable type tolerance, and the equivalent input impedance of the cellular module at the RF port, a physical calculation closed loop for mismatch margin is established. This enables rapid and quantitative identification of abnormal signals when link mismatch is caused by structural environmental changes such as condensation in the condensation joint area. It can clearly distinguish RF link mismatch caused by condensation from other mismatch factors such as manufacturing tolerances and temporary interference, thereby improving the accuracy of RF link health status judgment and the physical traceability of the judgment criteria. This avoids the decrease in equipment operation and maintenance efficiency or the increase in the risk of signal interruption due to misjudgment or omission.

In this invention, the initial temperature difference of the through-cabin metal plate, the thermal conductivity enhancement ratio of the cold bridge to the through-cabin metal plate, and the moisture retention coefficient are introduced into the flow cytometry calculation process as thermal and humidity risk parameters. By collecting the temperature and humidity inside the metal control cabinet and the surface temperature of the through-cabin metal plate in real time, and combining the structural thermal bridge and local moisture retention cavity effect in the condensation joint area, a multi-parameter, physically correlated incremental temperature compensation calculation link is established. This can dynamically track the condensation risk on the surface of the metal plate and can uniformly incorporate the structural differences of different cabinets, cables, and environments into the real-time compensation strategy, thereby improving the adaptability and safety of the compensation decision.

[0049] 3. In this invention, through automatic addressing, structural path key generation and control plan issuance, precise positioning and directional control of cabinets, panels and transmission channels are achieved. It supports concurrent linkage of multiple cabinets and multiple interfaces and real-time switching of multiple scenarios. The streaming decision engine only issues temperature adjustment commands when condensation causes mismatch, avoiding energy waste and overheating, and effectively improving the level of operation and maintenance automation and the overall energy efficiency ratio.

[0050] The accompanying drawings, which are included to provide a further understanding of the invention and form part of this application, illustrate exemplary embodiments of the invention and, together with their description, serve to explain the invention and do not constitute an undue limitation thereof. In the drawings:

[0051] Figure 1 A functional block diagram of a streaming computing engine system applicable to various scenarios is provided in one embodiment of the present invention;

[0052] Figure 2 This is a flowchart illustrating a streaming computing engine method applicable to various scenarios, provided as an embodiment of the present invention. Detailed Implementation

[0053] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0054] Example: This example provides a streaming computing engine system suitable for various scenarios. See [link to example]. Figure 1 Specifically, including:

[0055] The mismatch assessment module is used to calculate the mismatch margin of the RF link based on the characteristic impedance of the RF transmission line, the cable type tolerance, and the equivalent input impedance of the cellular module at the RF port.

[0056] In embodiments of the present invention, the mismatch margin of the RF link is calculated based on the characteristic impedance of the RF transmission line, the cable type tolerance, and the equivalent input impedance of the cellular module at the RF port, including:

[0057] The reflection coefficient of the cellular module at the radio frequency port is calculated based on the voltage standing wave ratio of the cellular module.

[0058] Specifically, first, the measured value of the voltage standing wave ratio (VSWR) of the cellular module's RF port at the current sampling time is obtained. Then, based on the inherent correlation between VSWR and reflection coefficient in the RF field, the industry-standard conversion formula is used for calculation. That is, by substituting the obtained VSWR value into the reflection coefficient calculation formula, where the reflection coefficient calculation formula is (VSWR value minus 1) divided by (VSWR value plus 1), the reflection coefficient of the cellular module at the RF port at the current sampling time is obtained.

[0059] Specifically, a cellular module is a communication unit that integrates radio frequency transceiver, power management, and signal processing functions to enable wireless data interaction between devices and base stations in a cellular network environment; voltage standing wave ratio (VSWR) represents the proportion of standing wave amplitude formed by energy reflection of radio frequency signals on the transmission line, and is used to measure the matching degree of the signal transmission path and energy loss; reflection coefficient represents the ratio between the incident energy and the reflected energy of the radio frequency signal at the port, and is used to reflect the port impedance matching state and the intensity of energy reflection.

[0060] Based on the reflection coefficient and the characteristic impedance of the RF transmission line, the equivalent input impedance of the RF port is calculated. The formula for calculating the equivalent input impedance is as follows:

[0061]

[0062] In the formula, It is the equivalent input impedance at the i-th sampling time. It is characteristic impedance. It is the reflection coefficient at the i-th sampling time, where i is the identifier of the sampling time;

[0063] Specifically, in radio frequency transmission line theory, characteristic impedance is the inherent impedance property of the transmission line itself, reflecting its impediment to electromagnetic energy transmission under ideal conditions; the reflection coefficient is used to quantify the energy ratio of the incident wave and the reflected wave at the port, reflecting the influence of impedance matching on signal reflection. When a signal propagates in a transmission line, the equivalent input impedance at the port is the overall impedance presented by the transmission line under the interaction of the incident and reflected waves. From the perspective of the superposition effect of the incident and reflected waves, and The proportional relationship can comprehensively reflect the roles of incident and reflected waves in impedance formation. Combined with characteristic impedance, this allows for further analysis. The calculation can accurately characterize the overall degree of obstruction to electromagnetic energy transmission at the transmission line port due to the superposition of incident and reflected waves at the i-th sampling time, which conforms to the interaction law between transmission line impedance and wave in radio frequency circuits.

[0064] Specifically, the equivalent input impedance represents the degree to which the RF port obstructs the transfer of electromagnetic energy during signal transmission, and is used to measure the matching status of energy transmission in the RF system; the characteristic impedance represents the inherent impedance of the RF transmission line when transmitting electromagnetic energy along the line under ideal conditions, and is an important constant that determines the signal power transmission efficiency; the sampling time identifier represents the time sequence of impedance measurement of the RF port signal, and is used to distinguish the sampling results of each continuous measurement.

[0065] The impedance lower limit difference is obtained by subtracting the characteristic impedance, the cable type tolerance of the RF transmission line and the equivalent input impedance.

[0066] The mismatch margin of the RF link is obtained by performing an upper-zero operation on the difference between zero and the lower impedance limit.

[0067] Specifically, the characteristic impedance is subtracted from the cable type tolerance to obtain the difference result. Then, the equivalent input impedance is subtracted from the difference result to obtain the lower limit difference of impedance. Finally, a zero-to-zero operation is performed on zero and the lower limit difference of impedance. That is, if the lower limit difference of impedance is greater than zero, the result is the lower limit difference of impedance. If the lower limit difference of impedance is less than or equal to zero, the result is zero. This result is the mismatch margin of the RF link, which is used to evaluate the matching margin and energy transmission efficiency of the entire RF system.

[0068] Specifically, cable type tolerance indicates the range of impedance deviation caused by differences in geometric dimensions, dielectric constant, and shielding layer thickness during the manufacturing process of RF transmission lines, and is used to characterize the consistency and stability of RF transmission channels; the lower limit impedance difference indicates the minimum difference between characteristic impedance and equivalent input impedance, and is used to quantify the degree of port matching deviation of transmission lines; mismatch margin indicates the remaining part of power reflection and loss caused by impedance mismatch in the RF link, and is used to evaluate the matching margin and energy transmission efficiency of the entire RF system.

[0069] Specifically, in an RF link, characteristic impedance is an inherent and ideal impedance property of the RF transmission line, determining the efficient transmission of signal power. Cable profile tolerance reflects the impedance deviation range caused by manufacturing differences in the RF transmission line, embodying the consistency and stability of the transmission channel. Equivalent input impedance is the actual impedance presented at the port after the combined effects of incident and reflected waves. By subtracting the cable profile tolerance from the characteristic impedance, the difference is obtained. Then, by subtracting the equivalent input impedance from the difference, the lower limit impedance difference is obtained, which quantifies the degree of deviation in the port matching of the transmission line. Mismatch margin is an indicator that measures the remaining power reflection and loss caused by impedance mismatch in the RF link, used to evaluate the system matching margin and energy transmission efficiency. The zero-rounding operation is performed on zero and the lower limit impedance difference because when the lower limit impedance difference is greater than zero, it indicates that there is a power reflection and loss margin caused by impedance mismatch, and the calculation result is this margin; when the lower limit impedance difference is less than or equal to zero, it indicates that there is no additional mismatch loss margin, and the calculation result is zero.

[0070] Specifically, the coupling effect of water film formation and metal cold bridge thermal conduction in the condensation junction area can cause the port impedance to deviate from the transmission line design baseline, resulting in increased power reflection and decreased link throughput. This further triggers session reconstruction and network domain jitter, causing disordered message arrival order and multi-peak distribution for the same device key within the maintenance window. To distinguish this structural anomaly from acceptable deviations within manufacturing tolerances, it is necessary to quantitatively compare the port's equivalent input impedance and characteristic impedance, as well as their type spectrum tolerances, to calculate the mismatch margin of the RF link and numerically provide the out-of-bounds magnitude and availability margin. The mismatch margin serves as a criterion for whether and how much intervention is needed, enabling the streaming engine to stably convert data into actions according to risk priority within the cross-domain maintenance window. Furthermore, it provides definite trigger thresholds and shutdown conditions for subsequent heating and dehumidification plans, suppressing link mismatch and state tearing caused by the condensation junction area at the source.

[0071] The thermal and humidity characteristic module is used to calculate the initial temperature difference of the metal plate passing through the compartment in the metal control cabinet, and to calculate the thermal conductivity enhancement ratio and moisture retention coefficient of the cold bridge in the condensation joint area to the metal plate passing through the compartment.

[0072] In an embodiment of the present invention, calculating the initial temperature difference of the metal plate penetrating the compartment in the metal control cabinet includes:

[0073] The dew point temperature of the metal control cabinet is calculated based on the internal temperature and relative humidity. The formula for calculating the dew point temperature is as follows:

[0074]

[0075] In the formula, It is the dew point temperature. It refers to the internal temperature of the metal control cabinet. It is the relative humidity of the metal control cabinet; a and b are constants in the Magnus empirical formula.

[0076] Specifically, dew point temperature is defined as the temperature at which the existing water vapor pressure in the air equals the saturated water vapor pressure at a given temperature. The actual water vapor pressure inside the cabinet is equal to the relative humidity multiplied by the saturated water vapor pressure at the current temperature. The relationship between saturated water vapor pressure and temperature can be expressed as an exponential relationship using the Magnus empirical formula. Therefore, setting the saturated water vapor pressure corresponding to the dew point temperature as the relative humidity multiplied by the saturated water vapor pressure at the cabinet temperature, taking the natural logarithm after equivalence, and substituting it into the Magnus coefficients a and b, yields the equation: a multiplied by the cabinet temperature divided by b plus the cabinet temperature plus... The equation is equal to a multiplied by the dew point temperature divided by b minus the dew point temperature. Rearranging this equation algebraically, we get the dew point temperature as b multiplied by a multiplied by the cabinet temperature plus b plus the cabinet temperature, then multiplied by... Divide the whole by a, multiply by b, subtract b, add the cabinet temperature, and multiply by b. This shows that the expression is the result of converting the temperature and relative humidity inside the cabinet into dew point temperature through the water vapor pressure balance relationship, and can accurately give the critical temperature at which the air reaches saturation and begins to condense.

[0077] Specifically, dew point temperature is used to characterize the critical temperature at which water vapor in the air begins to condense into droplets. Its calculation relies on the thermodynamic equilibrium relationship between air temperature and relative humidity. The internal temperature of a metal control cabinet represents the average kinetic energy of gas molecules within the cabinet, determining the maximum amount of water vapor that the air can hold. Relative humidity reflects the ratio of the current water vapor pressure to the saturation water vapor pressure, indicating how close the moisture content in the air is to the saturation value. When the temperature decreases or the humidity increases, causing the actual water vapor pressure to reach the saturation water vapor pressure, the air reaches the dew point and begins to form a condensation film. Constants a and b are fitting coefficients in the Magnus empirical formula, determined through numerous experiments, used to accurately describe the exponential relationship between water vapor pressure and temperature in different temperature ranges. This formula converts temperature and humidity into dew point temperature, which can be used to determine whether there is a risk of condensation inside the metal control cabinet, thus providing a basis for climate control and protection strategies.

[0078] Measure the actual surface temperature of the metal plate penetrating the compartment;

[0079] Specifically, a through-cabinet metal plate refers to a conductive structural component used to allow cables, radio frequency transmission lines, and other dielectric conductors to pass through the isolation wall within a sealed metal control cabinet or equipment compartment. This metal plate is typically made of a metal material with high thermal conductivity and corrosion resistance, with one side exposed to the external environment and the other side in direct contact with the internal climate space of the cabinet.

[0080] The initial temperature difference is obtained by calculating the difference between the dew point temperature and the actual surface temperature of the metal plate penetrating the compartment.

[0081] Specifically, the actual surface temperature of the metal plate through the cabin is used to reflect the steady-state thermal equilibrium of the metal plate under the current thermal environment. Its value depends on the thermal conductivity of the metal plate material, the plate thickness, and the temperature difference distribution between the inside and outside of the plate. The initial temperature difference reflects the thermal distance of the metal plate surface to the condensation critical point, which is used to assess the risk of condensation under the current thermal conduction state and provide basic data for subsequent temperature compensation and climate control.

[0082] Specifically, the dew point temperature is the critical temperature at which water vapor in the air begins to condense into droplets, reflecting the temperature threshold at which air reaches a saturated condensation state. The actual surface temperature of the metal plate penetrating the cabin reflects the temperature state of the metal plate after heat conduction and thermal equilibrium under the current thermal environment. When the difference between the dew point temperature and the actual surface temperature of the metal plate penetrating the cabin is calculated, the resulting initial temperature difference can quantify the gap between the surface temperature of the metal plate and the critical temperature for air condensation. From the physical laws of heat transfer and condensation, this temperature difference is directly related to the probability of water vapor condensation near the surface of the metal plate penetrating the cabin: if the initial temperature difference is positive, it means that the surface temperature of the metal plate is higher than the dew point temperature, and condensation is unlikely to occur at present; if the initial temperature difference is negative or close to zero, it means that the surface temperature of the metal plate is close to or lower than the dew point temperature, and there is a risk of condensation.

[0083] Specifically, calculating the initial temperature difference is crucial for accurately identifying the critical thermo-humidity state of the control cabinet's internal structure before condensation occurs. In metal control cabinets, the air temperature and relative humidity fluctuate over time due to diurnal temperature variations or load changes. When the metal surface temperature drops below the dew point, moisture in the air condenses into a water film, leading to damp signal connectors or RF link mismatch. By calculating the difference between the dew point temperature and the actual surface temperature of the metal plate penetrating the compartment, the distance between the current temperature and humidity state and the condensation threshold can be quantified, reflecting the proximity of the condensation risk. This is a key parameter for subsequently determining whether the condensation connector area requires compensatory heating or dehumidification.

[0084] In embodiments of the present invention, calculating the thermal conductivity enhancement ratio and moisture retention coefficient of the cold bridge across the compartment metal plate in the condensation joint area includes:

[0085] Calculate the heat conduction path area between the RF transmission line and the metal plate penetrating the compartment through the crimp connector;

[0086] Specifically, firstly, the effective contact range between the outer conductor of the RF transmission line and the through-hole metal plate in the crimping area is determined, and the perimeter and radial dimensions of the contact surface are obtained through geometric modeling or structural drawings. Based on the crimping depth of the crimping joint and the thickness of the metal plate, the extension direction and equivalent cross-sectional shape of the thermal channel are determined, and the contact surface is projected along the normal direction to form the calculated cross-section of the heat conduction path. The boundary of the contact area is corrected, taking into account the microscopic plastic deformation caused by the crimping pressure and the difference in coating thickness, and the theoretical geometric area is corrected to the actual heat conduction area. The corrected contact area is used as the effective conduction cross-section of the thermal channel for subsequent heat conduction calculations and cold bridge analysis.

[0087] Specifically, the heat conduction path area refers to the equivalent cross-sectional area of ​​the metal contact area formed by the contact between the RF transmission line and the metal plate through the crimp connector. It is used to characterize the geometric width and coverage of heat that can pass through this interface. The crimp connector is a metal connection component that forms an electrical and thermal connection between the RF transmission line and the metal plate through the compartment. Its function is to achieve a stable contact between the signal conductor and the plate through mechanical crimping, so that the signal path maintains low impedance continuity, and at the same time establishes an efficient heat conduction channel between the conductor interfaces.

[0088] For example, taking the connection between a radio frequency transmission line and a metal plate penetrating the compartment as an example, firstly, the effective contact range between the outer conductor of the radio frequency transmission line and the metal plate penetrating the compartment in the crimping area is determined. Through geometric modeling, it is known that the contact surface is circular, with a perimeter diameter of 10 mm and a radial dimension, i.e., the radius of the contact circle, of 5 mm. Based on the crimping depth of 2 mm and the thickness of the metal plate of 3 mm, the heat channel is determined to extend along the normal direction perpendicular to the surface of the metal plate, with an equivalent cross-sectional shape of a circle. The contact surface is projected along the normal direction to form the calculated cross-section of the heat conduction path. Theoretically, the area of ​​this circular cross-section is 78.5 square millimeters. The boundary of the contact area is corrected, considering the micro-plastic deformation caused by the crimping pressure, which reduces the actual contact radius by 0.5 mm, and the difference in plating thickness by 0.1 mm. After comprehensive calculation, the theoretical geometric area is corrected, and the actual heat conduction area is obtained as 63.585 square millimeters. This corrected contact area of ​​63.585 square millimeters is taken as the effective conduction cross-section of the heat channel.

[0089] Calculate the equivalent thermal conductivity of the radio frequency transmission line between the crimp connector and the metal plate penetrating the compartment;

[0090] Specifically, the process begins by identifying the layers of material between the RF transmission line and the metal plate passing through the crimp connector, including the outer conductor, crimp sleeve, solder or sealing layer, and micro-gaps on the plate surface. The thickness and known thermal conductivity of each layer are then determined. Based on the formula for calculating thermal resistance, the thermal resistance of each layer is calculated; thermal resistance is the ratio of material thickness to its thermal conductivity. The thermal resistances of each layer are then combined in series to obtain the overall thermal resistance of the multilayer material combination. Based on the relationship between the equivalent thermal conductivity and the overall thermal resistance, and considering the relevant dimensions of the heat conduction path, the equivalent thermal conductivity between the RF transmission line and the metal plate passing through the crimp connector is calculated. This equivalent thermal conductivity characterizes the overall thermal conductivity of the multilayer material combination.

[0091] For example, taking the connection between a certain radio frequency transmission line and a through-hole metal plate as an example, the materials between the radio frequency transmission line and the through-hole metal plate through the crimp connector are first identified, including the outer conductor, crimp sleeve, solder, and micro gap on the board surface. The outer conductor has a thickness of 2 mm and a thermal conductivity of 200 W / (m·K); the crimp sleeve has a thickness of 1 mm and a thermal conductivity of 150 W / (m·K); the solder has a thickness of 0.5 mm and a thermal conductivity of 80 W / (m·K); and the micro gap on the board surface has a thickness of 0.1 mm and a thermal conductivity of 0.02 W / (m·K). Based on the thermal resistance calculation formula, the thermal resistance of each material layer is calculated separately: the thermal resistance of the outer conductor is 2 ÷ 200 = 0.01 m²·K / W, the thermal resistance of the crimp sleeve is 1 ÷ 150 ≈ 0.0067 m²·K / W, the thermal resistance of the solder is 0.5 ÷ 80 = 0.00625 m²·K / W, and the thermal resistance of the micro-gap on the board surface is 0.1 ÷ 0.02 = 5 m²·K / W. Combining the thermal resistances of each material layer in series, the overall thermal resistance is 0.01 + 0.0067 + 0.00625 + 5 = 5.02295 m²·K / W. Given the relevant dimensions of the heat conduction path, the cross-sectional area of ​​the heat conduction path is 100 mm² (i.e., 0.0001 m²), and the length of the heat conduction path is the sum of the thicknesses of each material layer, i.e., 2 + 1 + 0.5 + 0.1 = 3.6 mm. Based on the relationship between equivalent thermal conductivity and overall thermal resistance, the equivalent thermal conductivity is the length of the heat conduction path divided by (overall thermal resistance multiplied by the cross-sectional area of ​​the heat conduction path), i.e., 0.0036÷(5.02295×0.0001)≈7.17W / (m·K). Therefore, the equivalent thermal conductivity between the RF transmission line and the metal plate through the crimp connector is approximately 7.17W / (m·K), which is used to characterize the overall thermal conductivity of these multilayer materials.

[0092] Multiply the equivalent thermal conductivity by the area of ​​the heat conduction path to obtain the amount of cold bridge heat conduction channels;

[0093] Specifically, the equivalent thermal conductivity refers to the overall thermal conductivity of the combination of multiple layers of materials, such as the outer conductor, the press sleeve, the solder or sealing layer, and the micro gaps on the plate surface, combining the thermal resistance of each layer into a single heat transfer constant; the thermal conductivity of the cold bridge refers to the total heat transfer capacity of the interface obtained by multiplying the equivalent thermal conductivity by the area of ​​the heat conduction path, which is used to represent the steady-state heat flux intensity that the cold bridge can transfer under a unit temperature difference, and to depict the dominant influence of the cold bridge on the surface temperature change of the metal plate penetrating the compartment.

[0094] Specifically, the "cold bridge" in the thermal conductivity channel quantity refers to a laminated cold bridge. A laminated cold bridge is a highly thermally conductive composite channel structure in a metal control cabinet, formed by the close contact and tight stacking of multiple layers of metal materials, including a through-chamber metal plate, crimped RF connectors, outer conductor sleeves, and cable shielding layers. This structure physically establishes a continuous heat conduction path from the external environment to the air inside the cabinet, allowing the low external temperature to be rapidly transferred to the interior along the interlayer metal surfaces, resulting in a significantly lower local surface temperature than the surrounding area. The thermal conductivity channel quantity of the cold bridge is used to quantify the steady-state heat transfer capacity of this highly thermally conductive channel under a unit temperature difference. The presence of a laminated cold bridge compromises the overall thermal insulation of the metal control cabinet, causing the condensation joint area to become the main location for heat loss and water vapor condensation. Therefore, the thermal conductivity channel quantity of the cold bridge not only reflects the intensity of heat dissipation but also assesses the risk of condensation and compensates for heating requirements. It is a crucial fundamental parameter for subsequent calculations of the thermal conductivity enhancement ratio of the through-chamber metal plate due to the cold bridge.

[0095] Specifically, multiplying the equivalent thermal conductivity by the heat conduction path area yields the thermal conductivity of a cold bridge because, after applying the steady-state heat transfer law to adjust for the series thermal resistance of the composite interface, the equivalent thermal conductivity is defined as the heat flux intensity that the interface can transfer per unit area and per unit temperature difference, also known as the overall heat transfer coefficient, measured in watts per square meter per Kelvin. The heat conduction path area, measured in square meters, represents the effective geometric cross-section on the cold bridge that actually participates in heat transfer. Multiplying the two yields a quantity in watts per Kelvin, which precisely corresponds to the total heat flux capacity that the cold bridge can pass through under a unit temperature difference—that is, the thermal conductivity. Since the equivalent thermal conductivity incorporates the thickness and thermal conductivity of each layer of material through thermal resistance synthesis, multiplying it by the area directly yields the overall heat transfer capacity of this channel, thus allowing for the quantification of the dominant role of cold bridges in the cooling rate of the plate surface.

[0096] Multiply the thermal conductivity of the through-hole metal plate by the thickness of the through-hole metal plate to obtain the thermal conductivity dimension of the plate.

[0097] Divide the amount of cold bridge heat conduction channels by the heat conduction dimension of the plate to obtain the heat conduction enhancement ratio of the cold bridge through-bus metal plate in the condensation joint area.

[0098] Specifically, the condensation junction area refers to the location on the metal control cabinet where radio frequency and signal cables are led out. It is a localized structure and microenvironmental area enclosed by a metal plate penetrating the compartment, cable crimpers and seals, external antennas or cable sheaths, and missing or malfunctioning breather valves. One side directly faces the external climate, while the other side connects to the air inside the cabinet. The close contact between metal parts forms a highly thermally conductive cold bridge channel. Narrow gaps and obstructions in front of the plate create a stagnant, moisture-trapping cavity with limited ventilation. This causes the surface temperature to drop below the dew point and water film to accumulate first during temperature and humidity fluctuations. This area also serves as a mechanical seal and electromagnetic shield, and is the main pathway for internal and external heat and moisture exchange. It has a decisive impact on the stability of the cabinet's climate and the impedance matching of the radio frequency link. Its geometry, thermal conductivity, and ventilation openings jointly determine the threshold and duration of condensation, making it the primary target for risk identification and temperature / humidity control.

[0099] Specifically, the thermal conductivity of the plate reflects the ability of the through-panel metal material to transfer heat under a unit temperature difference, while the plate thickness is the path length of heat across the plate. Multiplying the two yields the plate thermal conductivity scale, which characterizes the baseline heat transfer capacity of the inherent heat transfer channels, primarily the through-panel metal itself, under a unit temperature difference. The thermal conductivity of cold bridges reflects the heat transfer capacity of the additional thermal channels formed by the RF transmission lines and their crimping structures at the through-panel metal. Dividing the thermal conductivity of cold bridges by the plate thermal conductivity scale essentially compares the heat transfer capacity of the cold bridges with the baseline heat transfer capacity of the through-panel metal itself. The result measures the degree to which the additional thermal channels formed by the cold bridges enhance the thermal conductivity of the through-panel metal relative to its inherent heat transfer capacity. Therefore, this calculation yields the ratio of the thermal enhancement of the through-panel metal by the cold bridges in the condensation joint area.

[0100] Specifically, the thermal conductivity of the plate describes the ability of the through-pack metal plate material to transfer heat under a unit temperature difference. The higher the value, the easier it is for the plate to conduct external cold or internal heat along the thickness direction. The plate thickness is the path length that heat needs to travel across the plate. The thicker the plate, the greater the resistance to heat flow through the plate. The thermal conductivity of the plate is obtained by multiplying the thermal conductivity of the plate by the plate thickness. It is used to characterize the baseline heat transfer capacity of the inherent heat transfer channel, which is mainly based on the plate, under a unit temperature difference. The thermal conductivity enhancement ratio of the cold bridge in the condensation joint area to the through-pack metal plate is an indicator used to measure the degree of enhancement of the additional heat conduction channel formed by the RF transmission line and its crimping structure at the through-pack metal plate relative to the thermal conductivity of the plate itself. It reflects the degree of interference of the combined heat conduction path between local metal contact, thread fastening and cable sheath on the overall heat flow distribution. When the thermal conductivity enhancement ratio of the cold bridge to the through-pack metal plate is high, it means that the heat conduction channel in this area is stronger than the baseline channel of the plate. Heat is more easily transferred from the outside to the inside of the plate, so that the surface temperature at this point is lower than the surrounding area, forming a preferential condensation point.

[0101] The total ventilation cross-sectional area is obtained by adding the area of ​​the shielding area in front of the metal plate through the compartment and the effective ventilation area of ​​the corresponding ventilation section of the condensation joint area.

[0102] Specifically, the front obstruction area refers to the area inside the metal control cabinet where airflow is blocked by structural components, cable bundles, or sealing accessories before passing through the surface of the through-cabinet metal plate. This area restricts the free exchange of air on the plate surface. The effective ventilation surface of the ventilation section corresponding to the condensation joint area refers to the actual open area in which air can flow smoothly and participate in heat and moisture exchange in the ventilation channel formed between the through-cabinet metal plate, cable seals, and crimp joints. This ventilation surface reflects the flow capacity and degree of obstruction of airflow inside the metal control cabinet when passing through the condensation joint area, and is jointly affected by the cable layout, the opening size of the sealing structure, and the obstruction status of surrounding components. The total ventilation cross-sectional area is obtained by adding the above two and is used to characterize the overall airflow exchange capacity of the condensation joint area during steady-state operation.

[0103] The moisture retention coefficient of the condensation joint area is obtained by calculating the ratio of the area of ​​the shield in front of the panel to the total ventilation cross-sectional area.

[0104] Specifically, the moisture retention coefficient is an indicator used to describe the ease with which moist air can be retained and diffused in the condensation joint area. This coefficient reflects the phenomenon of humidity accumulation caused by obstruction, structural gaps, or insufficient moisture conduction channels in the air in the ventilation-restricted area. The magnitude of the moisture retention coefficient is closely related to the airflow area, the efficiency of moist air exchange, and the local temperature gradient. When the moisture retention coefficient is high, it means that the moist air stays in the area for a longer time, and the water vapor is not easily carried away. It is easy to form condensation or a film on the metal surface, which leads to a decrease in the insulation performance of the electrical joint or an increase in signal reflection.

[0105] It should be noted that moisture retention causes a sustained increase in water vapor concentration in a localized area. When the metal surface temperature approaches the dew point, condensation or a water film easily forms. The moisture retention coefficient is an indicator used to quantify this degree of moisture retention. By reflecting the proportional relationship between limited ventilation and gas exchange efficiency, a higher moisture retention coefficient indicates that moisture stays in that area for a longer period and is more difficult to diffuse. Moisture retention typically occurs within moisture retention chambers, which are locally enclosed spaces within metal control cabinets or equipment structures, formed by through-panel metal plates, cable seals, crimp joints, and surrounding structural components. These spaces are areas where humid air is trapped due to limited ventilation and narrow air exchange paths. Airflow within the moisture retention chamber is slow, and moisture diffusion is hindered. When a temperature difference exists between the inside and outside of the cabinet, water vapor easily condenses on the metal surface, forming a condensate film. Moisture retention chambers are located near condensation junction areas, where heat and moisture exchange are most uneven. The presence of moisture retention chambers amplifies the local humidity gradient, prolongs the condensation duration, and significantly affects the stability of RF connectors and electrical terminals.

[0106] Specifically, the moisture retention coefficient is defined as the ratio of the area of ​​the obstruction in front of the panel to the total ventilation cross-sectional area. This is based on the continuity of ventilation and the mechanism of convective mass transfer. The total ventilation cross-sectional area is obtained by adding the area of ​​the obstruction in front of the panel to the effective ventilation area, representing the total size of all geometric openings in this local cross-section. Under the same pressure difference and environmental conditions, the airflow per unit width is proportional to the available cross-section. The obstructed portion does not participate in gas exchange and will proportionally weaken the renewal rate of humid air. Therefore, using the ratio of the obstruction area to the total cross-section to characterize the tendency of humid air retention has dimensional consistency and a boundedness of zero to one: a ratio close to zero indicates smooth airflow and difficulty in moisture accumulation, while a ratio close to one indicates that the area is almost completely sealed and moisture is easy to accumulate. This ratio directly corresponds to the attenuation coefficient of local convective ventilation capacity, i.e., the moisture retention coefficient of the condensation junction area, used to quantify the retention intensity and diffusion difficulty of moisture in this area.

[0107] The temperature compensation increment module is used to calculate the target compensation temperature increment of the metal plate penetrating the compartment based on the thermal conductivity enhancement ratio, moisture retention coefficient and initial temperature difference of the cold bridge.

[0108] In embodiments of the present invention, the target compensation temperature increment of the through-tank metal plate is calculated based on the thermal conductivity enhancement ratio, moisture retention coefficient, and initial temperature difference of the cold bridge, including:

[0109] The amplification of the initial temperature difference is calculated based on the thermal conductivity enhancement ratio and moisture retention coefficient of the metal plate through the cold bridge. The formula for calculating the amplification is as follows:

[0110]

[0111] In the formula, It is a large amount. It is the thermal conductivity enhancement ratio of the cold bridge through-body metal plate. It is the moisture retention coefficient;

[0112] Specifically, the amplification factor represents the factor by which the initial temperature difference is amplified under the combined effects of cold bridge enhancement and moisture retention, and is used to measure the magnitude of the thermal response risk of local condensation. The formula for calculating the amplification factor considers both the degree of cold bridge enhancement and the moisture retention coefficient, reflecting the superimposed effect of thermal conduction pathways and moisture retention on local condensation. The coefficient 1 represents the equilibrium benchmark under ideal conditions with no enhancement and no moisture retention.

[0113] Specifically, in the heat and moisture interaction process of the condensation junction area, coefficient 1 represents the baseline multiple of the initial temperature difference under ideal conditions, i.e., when there is no cold bridge enhancement effect or moisture retention, and the temperature difference is not further amplified. The thermal conductivity enhancement ratio of the cold bridge to the through-chamber metal plate reflects the degree of enhancement of the thermal conductivity of the cold bridge formed by the RF transmission line and its crimping structure relative to the through-chamber metal plate itself. The moisture retention coefficient reflects the ease with which humid air is retained in the condensation junction area due to factors such as limited ventilation. When the thermal conductivity enhancement ratio of the cold bridge to the through-chamber metal plate and the moisture retention coefficient work together, cold bridge enhancement accelerates heat conduction, while moisture retention leads to moisture accumulation, further affecting heat exchange. The two work together through... The combination of these forms can comprehensively reflect the superimposed effect of cold bridge enhancement and moisture retention on temperature difference amplification. Multiplying this by the thermal conductivity enhancement ratio of the cold bridge through-tank metal plate yields the following result. This part quantifies the degree of additional amplification of the initial temperature difference caused by the combined effects of cold bridging and moisture retention. Finally, this additional amplification is added to the baseline factor of 1 to obtain the amplification amount, which can accurately characterize the factor by which the initial temperature difference is amplified under the combined effects of cold bridging and moisture retention, and is used to measure the thermal response magnitude of the risk of local condensation.

[0114] Multiply the amplified amount by the initial temperature difference to obtain the corrected temperature difference;

[0115] The zero-sum and correction temperature difference are subjected to an upper zero-rate operation to obtain the target compensation temperature increment of the through-tank metal plate.

[0116] Specifically, the magnitude of the corrected temperature difference is determined. If the corrected temperature difference is less than zero, it is set to zero; if the corrected temperature difference is greater than or equal to zero, its value remains unchanged. Through this zero-rounding operation, the target compensation temperature increment of the through-cabin metal plate is obtained, ensuring that the target compensation temperature increment is non-negative. This is used to offset the local cooling deviation caused by cold bridging and moisture retention, keeping the surface of the through-cabin metal plate above the dew point temperature, preventing condensation, and ensuring the stable operation of electrical connections and radio frequency links within the metal control cabinet.

[0117] Specifically, the amplification factor reflects the magnification of the initial temperature difference under the combined effects of cold bridge enhancement and moisture retention. Multiplying it by the initial temperature difference yields the corrected temperature difference, which comprehensively considers the effects of cold bridge thermal conductivity enhancement and moisture retention. The corrected temperature difference reflects the deviation of the actual cooling rate of the through-bay metal plate from the ideal state, and is a temperature difference parameter that better reflects the actual heat and moisture interaction. The purpose of rounding up to zero for both the zero and corrected temperature difference is to ensure that the target compensation temperature increment of the through-bay metal plate is non-negative.

[0118] Specifically, the corrected temperature difference refers to the effective temperature difference correction value obtained by comprehensively considering the enhanced thermal conductivity of cold bridges and the moisture retention effect based on the initial temperature difference. It reflects the deviation of the actual cooling rate of the through-bay metal plate from the ideal state. This correction reflects the true temperature gradient under the combined effect of local heat transfer and humidity accumulation, and is an important parameter for judging the critical state of condensation. The target compensation temperature increment refers to the additional temperature rise that needs to be applied to the surface of the metal plate, calculated based on the corrected temperature difference, to offset the local cooling deviation caused by enhanced cold bridges and moisture retention. By controlling the target compensation temperature increment in real time, it can be ensured that the surface of the through-bay metal plate is maintained above the dew point temperature, thereby avoiding condensation and maintaining the stable operation of electrical connections and radio frequency links within the metal control cabinet.

[0119] Specifically, calculating the target compensation temperature increment for the metal plate through the compartment based on the thermal conductivity enhancement ratio of the cold bridge, the moisture retention coefficient, and the initial temperature difference is to achieve precise control over the condensation risk of the metal control cabinet in a dynamic thermal and humidity environment. The thermal conductivity enhancement ratio of the cold bridge reflects the enhanced thermal conductivity of the metal channel, while the moisture retention coefficient reflects the degree of moisture retention caused by poor local ventilation. Together, they determine the rate of temperature drop and the intensity of humidity accumulation on the surface of the metal plate. When the difference between the ambient temperature and the dew point temperature is small, this combined effect will cause the plate surface to rapidly approach the condensation threshold. By combining these two influencing factors with the initial temperature difference, the actual thermal and humidity risk intensity of the condensation junction area can be quantified, thereby calculating the additional temperature rise required to offset the effects of cold bridges and moisture. The target compensation temperature increment is used to guide the climate control unit to implement active heating or dehumidification regulation, keeping the metal plate surface within a safe temperature range, avoiding condensation, and ensuring the stable operation of the RF link and control circuit.

[0120] The planning and decision-making module is used to determine whether to generate a control plan for the condensation joint area in the metal control cabinet based on the mismatch margin and the target compensation temperature increment.

[0121] In an embodiment of the present invention, based on the mismatch margin and the target compensation temperature increment, determining whether to generate a control plan for the condensation joint area in the metal control cabinet includes:

[0122] If both the mismatch margin and the target compensation temperature increment are greater than 0, it is determined that there is RF link mismatch caused by condensation in the condensation connector area, and a control plan for the condensation connector area is generated through the streaming computing engine; otherwise, no control plan is generated.

[0123] Specifically, condensation-induced RF link mismatch refers to the alteration of the electromagnetic boundary conditions between the metal conductor and the dielectric in the RF transmission path by the water film or liquid droplets formed in the condensation junction area. This causes a deviation from the originally designed characteristic impedance, resulting in signal reflection, phase disturbance, and power loss. The dielectric constant of condensate is much higher than that of air. When it forms a continuous water film on the surface of the pressure joint or through-hole metal plate, it changes the equivalent medium environment for electromagnetic wave propagation, leading to a mismatch between the input impedance and the load impedance, and an increased reflection coefficient. This type of mismatch can cause unstable RF signal transmission, increased link VSWR, and increased communication noise. In severe cases, it may cause link discontinuity or module overheating. By identifying this impedance change caused by condensation, control plans can be generated in a timely manner to adjust the temperature and humidity within the metal control cabinet, preventing further signal attenuation and equipment damage.

[0124] Specifically, the mismatch margin reflects the degree of deviation between the actual state and the ideal matching state of the RF link. When the mismatch margin is greater than 0, it indicates that the RF link has a certain degree of mismatch. The target compensation temperature increment is the additional temperature rise required to offset the local cooling deviation caused by cold bridge enhancement and moisture retention. Its value being greater than 0 means that it is currently necessary to raise the temperature to avoid condensation or mitigate the impact of condensation. If the mismatch margin is also greater than 0 at this time, combined with the fact that both are greater than 0, it indicates that this mismatch is not simply caused by other non-condensation factors, but rather by condensation in the condensation junction area, which changes the electromagnetic boundary conditions of the RF transmission path, causing the characteristic impedance to deviate from the design value, thus triggering the RF link mismatch. In this case, the streaming computing engine can quickly and dynamically generate a control plan for the condensation junction area based on parameters such as the current mismatch margin and the target compensation temperature increment, in order to adjust relevant environmental or equipment parameters and improve the transmission state of the RF link.

[0125] Specifically, when the conditions of both mismatch margin and target compensation temperature increment being greater than 0 are not met (i.e., mismatch margin is less than or equal to 0, target compensation temperature increment is less than or equal to 0, or both are less than or equal to 0), the planning decision module determines that there is no need to generate a control plan for the condensation joint area in the metal control cabinet, and the system enters the normal monitoring and maintenance state. Logically, a mismatch margin less than or equal to 0 means that the impedance matching state of the current RF link is within an acceptable range, and there is no significant mismatch problem caused by condensation; a target compensation temperature increment less than or equal to 0 indicates that the current temperature state of the through-cabin metal plate can avoid condensation without additional temperature compensation, and there is no need to adjust the temperature through the climate control unit. In subsequent operations, the instruction issuing module will not issue new temperature regulation control commands to the climate control unit. The climate control unit will maintain its existing operating mode and continue to routinely collect and monitor the temperature and humidity inside the metal control cabinet and the surface temperature of the metal plate penetrating the compartment. At the same time, the mismatch assessment module will continuously calculate the mismatch margin of the RF link based on the characteristic impedance of the RF transmission line, the cable type tolerance, and the equivalent input impedance of the cellular module. The thermal and humidity characteristic module and the temperature compensation increment module will also continuously update the initial temperature difference of the metal plate penetrating the compartment, the thermal conductivity enhancement ratio of the cold bridge to the metal plate penetrating the compartment, the moisture retention coefficient, and the target compensation temperature increment. The planning decision module will periodically perform conditional judgments on the updated mismatch margin and the target compensation temperature increment. Once both are detected to be greater than 0, the control plan generation process will be immediately initiated to ensure timely response to potential condensation risks and RF link mismatch issues, and to always ensure the stable operation of the electrical connections and RF links inside the metal control cabinet.

[0126] In embodiments of the present invention, the control plan includes:

[0127] The target surface temperature of the metal plate penetrating the compartment is obtained by adding the target compensation temperature increment and the actual surface temperature of the metal plate penetrating the compartment.

[0128] The serial numbers of the metal control cabinet, the metal plate penetrating the compartment, and the radio frequency transmission line are concatenated to obtain the path identifier string for the condensation connector area.

[0129] Specifically, the target compensation temperature increment is the additional temperature rise value used to offset the local cooling deviation caused by cold bridge enhancement and moisture retention. The actual surface temperature of the through-bay metal plate is the true temperature state of the plate under the current thermal and humidity environment and heat flow boundary. Adding the two together yields the target surface temperature that the through-bay metal plate should be stably maintained at. This temperature ensures that the plate surface is above the dew point to avoid condensation. The serial numbers of the metal control cabinet, the through-bay metal plate, and the RF transmission line correspond to unique physical identifiers for the physical equipment, specific board, and specific transmission channel, respectively. By concatenating these three serial numbers, the resulting path identifier string uniquely points to the actual heat transfer and signal path of the condensation joint area in the control and maintenance link. This provides an addressable basis for accurately sending the calculated target surface temperature to the corresponding physical object and executing temperature control operations, enabling precise control of specific condensation joint areas.

[0130] Specifically, the target surface temperature represents the safe temperature that the panel should be stably maintained to ensure it is above the dew point and to prevent condensation; the metal control cabinet number, the through-cabinet metal plate number, and the radio frequency transmission line number correspond to unique entity identifiers of physical equipment, specific panels, and specific transmission channels, respectively, to bind the calculation results to the field objects one by one; the path identifier string is an addressable string formed by connecting the above three entity identifiers in a fixed order, used to uniquely point to the actual heat transfer and signal path of the condensation joint area in the control and maintenance link, thereby supporting the subsequent issuance and execution of the target temperature.

[0131] Perform a hash operation on the path identifier string to obtain the structural path key of the condenser connector area;

[0132] Specifically, the path identifier string of the condenser connector area is first obtained. Using the selected hash algorithm, the path identifier string is used as input data. Through the hash algorithm's operation, the path identifier string of arbitrary length is converted into a hash value of fixed length. The resulting hash value is determined as the structural path key of the condenser connector area. This structural path key can reflect the physical location and electrical connection relationship of the condenser connector area inside the metal control cabinet, providing a basis for addressing subsequent control commands.

[0133] The system addresses and sends control commands to the climate control unit of the metal control cabinet according to the structural path key. The control command is to raise the temperature of the metal plate penetrating the cabin to the target surface temperature.

[0134] Specifically, the structural path key reflects the physical location and electrical connection of the condensation connector area inside the metal control cabinet, and serves as the basis for control command addressing; the climate control unit is an execution module installed inside the metal control cabinet responsible for performing temperature and humidity regulation tasks, used to drive heating or dehumidification components according to control signals; the control command is an operation command generated by the system based on the condensation risk calculation results, used to adjust the temperature gradient of the through-chamber metal plate and its adjacent area, so that its surface temperature reaches the previously calculated target surface temperature, thereby suppressing condensation formation and restoring the stable matching state of the RF link.

[0135] The command issuing module is used to issue control commands to the climate control unit of the metal control cabinet according to the control plan.

[0136] Specifically, the system first extracts key information from the generated control plan, including the structural path key of the condenser junction area, the target surface temperature of the through-cabinet metal plate, and the corresponding metal control cabinet number, through-cabinet metal plate number, and RF transmission line number. The system's command issuance module invokes the addressing function, performing a matching search in a pre-set device address mapping library based on the structural path key. This library stores the correspondence between the structural path key and the physical addresses of each climate control unit within the metal control cabinet. The search locates the specific position of the climate control unit to be executed. Following the climate control unit's command protocol format, the target surface temperature of the through-cabinet metal plate is converted into standardized temperature regulation parameters. Combined with the device identification information (metal control cabinet number and through-cabinet metal plate number), a complete control command is generated. The command content is clearly defined as follows: The system raises the temperature of the designated perforated metal plate to the target surface temperature. The command issuing module sends the generated control command to the addressed climate control unit via the internal communication link and a preset transmission protocol. After receiving the control command, the climate control unit first verifies the completeness and legality of the command. If the verification is successful, it parses the temperature parameters and device identifier in the command and drives its own temperature regulation components, such as the heating module, to start working. During the regulation process, the climate control unit collects the surface temperature data of the perforated metal plate in real time and compares it with the target surface temperature. It dynamically adjusts the output power of the regulation components according to the temperature difference until the surface temperature of the perforated metal plate is stably maintained at the target surface temperature. At the same time, it feeds back the execution status information to the command issuing module, completing the entire control command issuance and execution process.

[0137] Specifically, after the surface temperature of the through-cabin metal plate stabilizes at the target surface temperature, the climate control unit first continuously collects the surface temperature data of the through-cabin metal plate and compares it with the target surface temperature in real time to confirm that the temperature is stable and meets the standard without significant fluctuations. Simultaneously, it collects the internal temperature and relative humidity data of the metal control cabinet, calculates the dew point temperature under the current environment, and verifies that the surface temperature of the through-cabin metal plate is consistently higher than the dew point temperature, ensuring that the conditions for condensation formation have been eliminated. Next, the climate control unit feeds back the temperature stabilization information, the internal temperature and humidity data, and the dew point temperature verification results to the system's command issuance module. After receiving the feedback information, the command issuance module transmits it to the planning and decision-making module. The planning and decision-making module, combined with the previously calculated RF link mismatch margin, reassesses the RF link status of the condensation connector area to determine whether the RF link mismatch caused by condensation has been recovered. If the mismatch margin returns to the normal range and the temperature of the through-cabin metal plate remains stable at the target surface temperature, the planning and decision module determines that the current control task has been completed, generates a control task end command, and sends it to the command issuing module. The command issuing module then issues an adjustment command to the climate control unit, causing the climate control unit to switch from active heating regulation to constant temperature monitoring, maintaining only minimal temperature monitoring and fine-tuning functions. If the mismatch margin does not return to the normal range or the temperature becomes unstable, the planning and decision module triggers a secondary evaluation process, re-calling the thermal and humidity characteristic module and the temperature compensation increment module to recalculate the thermal conductivity enhancement ratio of the cold bridge to the through-cabin metal plate and the target compensation temperature increment, generating a new control plan and issuing it to the climate control unit through the command issuing module until the temperature of the through-cabin metal plate remains stable and the RF link mismatch problem is completely resolved, thereby ensuring the long-term stable operation of the electrical connections and RF links within the metal control cabinet.

[0138] In summary, the core technical problem this invention addresses is the mismatch in the radio frequency link caused by condensation in the condensation junction area within the metal control cabinet, which in turn compromises the reliability of electrical connections and the stability of radio frequency signal transmission. The control plan pre-includes the target surface temperature of the through-cabin metal plate and the addressing information of the corresponding climate control unit. The target surface temperature is precisely calculated using a cold bridge based on the thermal conductivity enhancement ratio, moisture retention coefficient, and initial temperature difference of the through-cabin metal plate, ensuring that the surface temperature of the through-cabin metal plate is always higher than the dew point temperature to suppress condensation at its source. The addressing information is determined through a structural path key, enabling precise location of the climate control unit corresponding to a specific condensation junction area. When the command issuing module sends control commands to the climate control unit according to the control plan, the command content clearly indicates that the temperature of the through-cabin metal plate should be raised to the target surface temperature. After receiving the command, the climate control unit will drive the internal heating or temperature regulation components to start working, and adjust the temperature of the through-cabin metal plate in real time until it is stably maintained at the target surface temperature, thereby completely eliminating the conditions for condensation formation in the condensation joint area. The elimination of condensation can directly solve the RF link impedance offset and mismatch problem caused by it, restore the RF link mismatch margin to the normal operating range, and ultimately ensure the safety of electrical connections and the stability of RF signal transmission in the metal control cabinet, thus effectively solving the existing technical problems.

[0139] It should be noted that the applicability of this invention to multiple scenarios lies in its ability to adapt to the operating environment of metal control cabinets under different working conditions. For example, it can cope with fluctuations in internal temperature and relative humidity of different metal control cabinets, differences in thickness and thermal conductivity of metal plates with different specifications, and variations in characteristic impedance and cable type tolerance of different types of radio frequency transmission lines. There is no need to adjust the core module architecture of the system for a single scenario. By simply using environmental parameters and equipment parameters under different scenarios as input data, the initial temperature difference, the thermal conductivity enhancement ratio of the cold bridge to the metal plate, and the moisture retention coefficient can be calculated through the thermal and humidity characteristic module, and the radio frequency link mismatch margin can be calculated through the mismatch assessment module, thereby adapting to the control requirements under different application scenarios.

[0140] It should be noted that the streaming computing engine plays a crucial role in the system's real-time computing core. It takes a continuously arriving data stream as input, performs online calculations in a time-series or event-driven manner, and immediately feeds back the results to the control module, achieving low-latency, high-concurrency data processing capabilities. Through the continuous operation of the streaming computing engine, this system can achieve synchronous response and decision updates under various operating conditions such as temperature and humidity changes, energy consumption fluctuations, or signal mismatches, demonstrating consistent scalability and real-time performance advantages across multiple scenarios.

[0141] In another embodiment, in the health field, cellular communication devices, with their wide coverage and highly reliable network transmission capabilities, have become a key cornerstone in building a smart healthcare ecosystem, empowering the intelligentization and universalization of medical services in multiple dimensions. In remote health monitoring scenarios, it supports the real-time and continuous transmission of physiological data from various wearable medical devices (such as smart ECG patches, non-invasive blood glucose monitors, and sleep apnea monitoring belts). For example, smart bracelets worn by patients with chronic diseases can synchronize core indicators such as heart rate, blood pressure, and blood oxygenation to the hospital's remote monitoring platform within seconds via a cellular network. Doctors can dynamically track changes in the patient's condition and adjust treatment plans in a timely manner without the patient's physical presence, effectively reducing the risk of acute complications.
