Description

Technical Field

[0001] This invention relates to the field of energy-saving technology for communication infrastructure, and in particular to a collaborative control method, electronic equipment, media, and products for an outdoor communication equipment room management system. Background Technology

[0002] The BBU, servers, and other communication equipment installed in outdoor communication equipment rooms continuously generate a large amount of heat during operation. To ensure reliable operation of the equipment, the ambient temperature inside the equipment room needs to be maintained within a stable range of 20-30℃. Currently, the widely adopted year-round uninterrupted air conditioning cooling solution has extremely high energy consumption, with electricity costs accounting for more than 30% of the total operating cost of the site, resulting in huge operating expenses and carbon emissions. Summary of the Invention

[0003] This invention provides a collaborative control method, electronic equipment, medium, and product for an outdoor communication equipment room management system, which solves the technical problem of excessive energy consumption in existing year-round uninterrupted air conditioning cooling solutions for outdoor communication equipment rooms.

[0004] This invention provides a collaborative control method for an outdoor communication equipment room management system. The management system includes an infrared radiation cooling skin, a forced ventilation cooling module, an air conditioning cooling module, an indoor temperature sensor, and a system controller. The infrared radiation cooling skin is installed on the outer wall of the outdoor communication equipment room, and its normal total emissivity is greater than or equal to a threshold. The collaborative control method is applied to the system controller and includes: The indoor temperature of the computer room is acquired in real time as monitored by the indoor temperature sensor. If the temperature inside the computer room is less than or equal to the first threshold, then the ventilation module and the air conditioning module are both kept off, and zero-power radiation heat dissipation is maintained only by the infrared radiation cooling skin. If the temperature inside the computer room is greater than the first threshold and less than or equal to the second threshold, then the air conditioning module is kept off and the ventilation module is started, wherein the first threshold is less than the second threshold; If the temperature inside the computer room is greater than the second threshold, then both the air conditioning module and the ventilation module will be started and running.

[0005] According to the collaborative control method of an outdoor communication equipment room management system provided by the present invention, the outdoor communication equipment room management system further includes an outdoor environment sensor; If the temperature inside the computer room is greater than the first threshold and less than or equal to the second threshold, then controlling the air conditioning module to remain off and starting the ventilation module includes: If the temperature inside the computer room is greater than the first threshold and less than or equal to the second threshold, the air conditioning module is controlled to remain off, and the outdoor environmental parameters monitored by the outdoor environmental sensor are acquired. Determine whether the preset ventilation conditions are met based on the outdoor environmental parameters; If the conditions are met, the ventilation module is activated; If the conditions are not met, the ventilation module will remain closed.

[0006] According to the present invention, a collaborative control method for an outdoor communication equipment room management system is provided, wherein the outdoor environmental parameters include the external temperature and the external relative humidity of the equipment room; The step of determining whether the preset ventilation conditions are met based on the outdoor environmental parameters includes: The system determines whether the external temperature of the computer room is lower than the internal temperature of the computer room, whether the difference between the internal temperature of the computer room and the external temperature of the computer room is greater than or equal to a preset temperature difference threshold, and whether the external relative humidity of the computer room is less than or equal to a preset humidity threshold. If the external temperature of the computer room is lower than the internal temperature of the computer room, the difference is greater than or equal to the preset temperature difference threshold, and the external relative humidity of the computer room is less than or equal to the preset humidity threshold, then the preset ventilation conditions are determined to be met.

[0007] According to the collaborative control method of an outdoor communication equipment room management system provided by the present invention, after controlling the air conditioning module and the ventilation module to start operation if the internal temperature of the equipment room is greater than the second threshold, the method further includes: Obtain the deviation between the internal temperature of the computer room and the preset target temperature; Based on the deviation value, the target operating frequency of the air conditioning module is calculated, and a corresponding frequency control signal is generated according to the target operating frequency; The frequency control signal is sent to the inverter of the air conditioning module so that the inverter outputs AC power of the corresponding frequency to drive the compressor of the air conditioning module to operate at the target operating frequency.

[0008] The collaborative control method for an outdoor communication equipment room management system provided by the present invention further includes: Acquire temperature change data of the computer room's internal temperature within a preset historical period; The cooling demand trend inside the computer room is determined based on the temperature change data; The first threshold and / or the second threshold are adjusted according to the cooling demand trend; wherein, when the cooling demand trend is continuously rising, the second threshold is lowered to start the air conditioning module in advance; when the cooling demand trend is continuously falling, the first threshold is raised to extend the duration of zero-power radiative heat dissipation by the infrared radiative cooling skin alone.

[0009] The collaborative control method for an outdoor communication equipment room management system provided by the present invention further includes: Obtain real-time operating power consumption data of the communication equipment inside the outdoor communication equipment room, and / or obtain predicted load data of the communication equipment inside the outdoor communication equipment room; Calculate the predicted temperature change based on the real-time operating power consumption data and / or the predicted load data; Based on the predicted temperature change, predict the time when the temperature inside the computer room will reach the second threshold. When the arrival time is less than a preset time threshold, both the air conditioning module and the ventilation module are started.

[0010] The collaborative control method for an outdoor communication equipment room management system provided by the present invention further includes: Get the preset safe temperature limit; Calculate the temperature difference between the internal temperature of the computer room and the preset safe upper temperature limit; When the temperature difference is less than or equal to a preset warning threshold, the temperature change data of the computer room interior within a preset historical period is obtained, and the current operating status information of the ventilation module and the air conditioning module is obtained. Based on the temperature change data, the operating status information, and the temperature difference, an early warning analysis report is generated; The early warning analysis report is sent to the operation and maintenance management platform so that the operation and maintenance management platform can display the early warning analysis report.

[0011] The present invention also provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the collaborative control method of the outdoor communication equipment room management system as described above.

[0012] The present invention also provides a non-transitory computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the collaborative control method of the outdoor communication equipment room management system as described above.

[0013] The present invention also provides a computer program product, including a computer program that, when executed by a processor, implements the collaborative control method of the outdoor communication equipment room management system as described above.

[0014] This invention provides a collaborative control method, electronic device, medium, and product for an outdoor communication equipment room management system. It acquires the internal temperature of the equipment room in real time from an indoor temperature sensor. If the internal temperature is less than or equal to a first threshold, both the ventilation module and the air conditioning module are kept off, and zero-power radiative heat dissipation is maintained solely by an infrared radiative cooling skin. If the internal temperature is greater than the first threshold but less than or equal to a second threshold, the air conditioning module is kept off while the ventilation module is activated, wherein the first threshold is less than the second threshold. If the internal temperature is greater than the second threshold, both the air conditioning module and the ventilation module are activated. This invention solves the technical problem of excessive energy consumption in year-round uninterrupted air conditioning cooling solutions for outdoor communication equipment rooms. Compared with existing technologies, this invention uses an infrared radiation cooling skin with a normal emissivity of not less than 0.88 as a permanent basic heat dissipation layer, ensuring the effectiveness of zero-power radiation heat dissipation in low-temperature ranges. Through a three-level gradient control based solely on the internal temperature of the equipment room, zero-power heat dissipation is achieved entirely by relying on this high-performance skin in low-temperature ranges, low-power ventilation replaces high-power air conditioning in medium-temperature ranges, and air conditioning is only activated in high-temperature ranges. This achieves precise matching between heat dissipation methods and real-time heat load, maximizing the utilization of free natural cooling sources and significantly reducing annual cooling energy consumption and operating costs while ensuring reliable operation of equipment in the equipment room.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0022] Figure 1 This is a flowchart illustrating the collaborative control method of the outdoor communication equipment room management system provided by the present invention. The collaborative control method is applied to the system controller, and the structure of the outdoor communication equipment room management system to which this method is applied is as follows: Figure 2 As shown, it includes an outdoor communication equipment room 1, an infrared radiation cooling skin 2 installed on the outer wall of the equipment room, a forced ventilation and cooling module 3, an air conditioning cooling module 4, a system controller 5, an indoor temperature sensor 51 installed inside the equipment room, and an outdoor temperature and humidity sensor 52 installed outside the equipment room. Figure 1 As shown, the cooperative control method includes the following steps: It should be noted that the infrared radiation cooling skin is applied to the outer wall of the outdoor communication equipment room, specifically, it can be completely applied to the roof and main sun-exposed side walls. This skin is a standardized product with specific performance parameters. At 80℃, its normal total emissivity, measured according to GB / T 18497.2-2019 standard, is not less than 0.88 (this value characterizes the skin's radiative heat dissipation capacity, exceeding the minimum threshold of 0.83 in the GB / T 30127-2013 textile standard, ensuring sufficient radiative heat dissipation capacity in high-temperature environments and providing a reliable physical basis for three-level gradient energy-saving control). It also exhibits highly efficient infrared radiation characteristics in the 8-13μm atmospheric window band, forming a permanent passive heat dissipation base layer and continuously providing zero-power radiative heat dissipation in all operating modes. The forced ventilation cooling module, which includes multiple variable-speed fans, can be installed in the equipment room cabinet door to introduce cool external air into the equipment room or accelerate air convection when outdoor environmental conditions are suitable. The air conditioning refrigeration module can be an inverter window air conditioner or a split-type air conditioner, used to actively reduce the internal temperature of the computer room through a compression refrigeration cycle. An indoor temperature sensor is installed in the return air duct or near the heat-generating area of ​​the equipment inside the computer room to monitor the internal temperature (Tin). The system controller uses an industrial PLC, located inside the computer room or in the electrical distribution box, and is connected to the indoor temperature sensor located inside the computer room and the outdoor temperature and humidity sensor located outside the computer room. The infrared radiation cooling skin, the forced ventilation cooling module, and the air conditioning refrigeration module are loosely coupled; that is, they are independent in physical installation, hardware connection, and operating mechanism, without direct rigid structural connection or refrigerant exchange, and only coordinate their functions by receiving unified control commands from the system controller. This architecture achieves fault isolation and functional redundancy.

[0023] It is understandable that the internal temperature of the computer room refers to the actual temperature of the air inside the outdoor communication computer room, which is collected in real time by an indoor temperature sensor installed inside the computer room and transmitted to the system controller.

[0024] In practical implementation, the system controller can be an industrial programmable logic controller (PLC), connected to the indoor temperature sensor via analog input ports or digital communication buses (such as RS485, Modbus protocol). The indoor temperature sensor can be a platinum resistance temperature sensor or a thermocouple temperature sensor, installed in a representative location near the return air duct or heat-generating area of ​​the equipment within the computer room. The system controller periodically reads sensor data according to a preset sampling period (e.g., 1 second to 60 seconds), performs necessary filtering on the raw data (such as moving average filtering) to eliminate transient interference, and stores the processed temperature value in an internal register as the current indoor temperature of the computer room. The system controller can also connect to multiple indoor temperature sensors simultaneously, averaging or taking the maximum value from the multiple sensor readings as the final indoor temperature of the computer room to improve the reliability and representativeness of the measurement.

[0025] Step 102: If the temperature inside the computer room is less than or equal to the first threshold, then control both the ventilation module and the air conditioning module to remain off, and maintain zero-power radiation heat dissipation only by the infrared radiation cooling skin. It should be noted that the first threshold is a preset temperature critical value used to define the temperature boundary between a low-temperature state and the need to activate active cooling measures. The ventilation module refers to a forced ventilation cooling module, including fans and related duct components, used to introduce cool air from outside the server room or accelerate heat exchange between the internal air and the external environment. The air conditioning module refers to an air conditioning refrigeration module, including compressors, evaporators, condensers, etc., used to actively reduce the internal temperature of the server room through a compression refrigeration cycle. Infrared radiation cooling skin is a functional layer material applied to the outer wall of the server room, with a normal total emissivity greater than or equal to 0.88, capable of directly dissipating the heat absorbed by the server room shell into the external space in the form of infrared radiation through atmospheric window bands.

[0026] Understandably, when the temperature inside the computer room is at a low level (not exceeding the first threshold), the cooling needs of the computer room can be met by relying solely on passive radiation cooling with zero power consumption. At this time, the active energy-consuming equipment (ventilation module and air conditioning module) are kept off to achieve maximum energy saving.

[0027] Step 103: If the temperature inside the computer room is greater than the first threshold and less than or equal to the second threshold, then control the air conditioning module to remain off and start the ventilation module, wherein the first threshold is less than the second threshold; It should be noted that the second threshold is another preset temperature boundary value, which is set to be greater than the first threshold (preferably, the first threshold can be set to 23℃ and the second threshold can be set to 28℃), used to define the dividing point between a moderate and a high temperature state in the computer room. The first threshold and the second threshold together constitute a temperature range—when the internal temperature of the computer room is within this range, it indicates that the computer room is at a moderate temperature level. At this time, the passive radiative heat dissipation capacity of the infrared radiative cooling skin alone is insufficient to maintain the computer room temperature at a low level, but it has not yet reached the urgent level that requires the activation of the air conditioning cooling module. Specifically, when the internal temperature of the computer room is greater than the first threshold and less than or equal to the second threshold, the system controller sends a control signal to the air conditioning module to keep it off, and at the same time sends a start control signal to the ventilation module. In this state, the compressor of the air conditioning module does not work and the cooling cycle does not run, thereby avoiding the activation of high-power cooling equipment; after the ventilation module is activated, its fan generates forced airflow, accelerating the convective heat transfer between the air inside the computer room and the external environment, supplementing the passive heat dissipation capacity of the infrared radiative cooling skin with lower power consumption (only the fan consumes power), and together controlling the internal temperature of the computer room within an acceptable range.

[0028] In its implementation, after determining that the temperature inside the computer room falls between a first and a second threshold, the system controller sends a stop-and-hold command to the air conditioning module's control board via its output port to ensure the power supply contactor for the air conditioning compressor remains disconnected. Simultaneously, it sends a start command to the ventilation module's motor driver via its output port, energizing the fan drive circuit and causing the fan to begin rotating. The ventilation module can contain multiple fans, and the system controller can control one or more fans to start as needed. The system controller can control the fans to operate at a constant speed or adjust their speed based on the specific temperature position within the range (e.g., closer to the first or second threshold). The infrared radiation cooling skin continues to operate in this state.

[0029] Step 104: If the temperature inside the computer room is greater than the second threshold, then control both the air conditioning module and the ventilation module to start running.

[0030] It should be noted that the start-up of the air conditioning module means that the compressor's refrigeration cycle begins to work, actively transferring heat from inside the computer room to the external environment. The start-up of the ventilation module means that the fan begins to run, introducing cool outside air or accelerating airflow to enhance heat dissipation.

[0031] Understandably, when the temperature inside the computer room rises above the second threshold, it indicates that passive radiative cooling is no longer sufficient to meet the cooling needs of the computer room, and all available active cooling methods must be activated to quickly and forcibly reduce the temperature of the computer room to a safe range.

[0032] In a specific implementation, after the system controller determines that the temperature inside the computer room is greater than the second threshold, it sends a start command to the control board of the air conditioning module through a digital output port or a communication bus, causing the air conditioning compressor contactor to close and the compressor motor to be powered on and operate. At the same time, the condenser fan and the evaporator fan are started; a start command is sent to the motor driver of the ventilation module, causing the ventilation fan to be powered on and operate. The start of the air conditioning module can be set to operate at full power or can be frequency-converted according to the difference between the temperature inside the computer room and the preset target temperature. The ventilation module can be started simultaneously with the start of the air conditioner or can be started with a delay after the air conditioner is started. When the temperature inside the computer room drops below the second threshold due to active cooling, the system controller switches to the corresponding low-power mode according to the temperature range.

[0033] It should be noted that after one year of actual deployment and testing in a base station in Beijing, the operating time of the air conditioning compressor of this system is reduced by about 45% compared with the traditional all-year air conditioning solution, and the total annual cooling power consumption of the site is reduced by about 35%, verifying the significant energy-saving effect of this solution.

[0034] In a specific implementation, as Figure 3 shown, the collaborative control method specifically includes the following control processes: First, initialize the preset parameters, including the first threshold of 23 °C, the second threshold of 28 °C, the preset target temperature of 25 °C, the safety temperature upper limit of 35 °C, and the ventilation condition (the outdoor temperature is at least 3 °C lower than the indoor temperature and the humidity is lower than 70%). The system controller collects the indoor temperature Tin and the outdoor temperature and humidity at a preset period. When Tin > 35 °C, immediately execute the third-level full-power cooling and issue an audible and visual alarm; otherwise, execute a three-level gradient control: when Tin ≤ 23 °C, turn off the ventilation and air conditioning, and only rely on the infrared radiation cooling skin for zero-power heat dissipation; when 23 °C < Tin ≤ 28 °C, turn off the air conditioning, and start the ventilation module if the ventilation condition is met; when Tin > 28 °C, start the air conditioning and ventilation modules, and the PID algorithm adjusts the operating frequency of the compressor according to the deviation between Tin and 25 °C. The skin works continuously throughout the process and records the operating data. For example, when Tin = 22 °C, execute the first level; when Tin = 26 °C and the ventilation condition is met, execute the second level; when Tin = 29 °C, the PID adjusts the compressor frequency according to a 4 °C deviation, and the system achieves an accurate match between the heat dissipation means and the heat load.

[0035] This invention uses an infrared radiation cooling skin with a normal emissivity of not less than 0.88 as a permanent base heat dissipation layer, ensuring the effectiveness of zero-power radiation heat dissipation in low-temperature ranges. Through a three-level gradient control system with the internal temperature of the computer room as the sole core criterion, zero-power heat dissipation is achieved entirely by relying on this high-performance skin in low-temperature ranges, low-power ventilation replaces high-power air conditioning in medium-temperature ranges, and air conditioning is only activated in high-temperature ranges. This achieves precise matching between heat dissipation methods and real-time heat load, maximizing the utilization of free natural cold sources and significantly reducing annual cooling energy consumption and operating costs while ensuring the reliable operation of computer room equipment.

[0036] Based on any of the above embodiments, the outdoor communication equipment room management system further includes an outdoor environment sensor; the step of controlling the air conditioning module to remain off and activating the ventilation module if the internal temperature of the equipment room is greater than the first threshold and less than or equal to the second threshold includes: If the temperature inside the computer room is greater than the first threshold and less than or equal to the second threshold, the air conditioning module is controlled to remain off, and the outdoor environmental parameters monitored by the outdoor environmental sensor are acquired. Determine whether the preset ventilation conditions are met based on the outdoor environmental parameters; If the conditions are met, the ventilation module is activated; If the conditions are not met, the ventilation module will remain closed.

[0037] It should be noted that outdoor environmental sensors are sensing devices installed outside the computer room to monitor the environmental conditions outside the room. Outdoor environmental parameters refer to physical quantities characterizing the external environment of the computer room, including at least outdoor air temperature and humidity. Specifically, outdoor environmental sensors may include outdoor temperature sensors and outdoor relative humidity sensors, which can be integrated into a single multi-parameter sensing module or installed separately. The system controller connects to the outdoor environmental sensors via analog input ports or a digital communication bus, reading outdoor environmental parameters at the same sampling period as the indoor temperature sensor or at a separate sampling period. The outdoor temperature sensor should be installed outside the computer room in a well-ventilated location, away from direct sunlight, and the outdoor relative humidity sensor should be installed inside a rainproof and moisture-proof protective cover.

[0038] Understandably, preset ventilation conditions are a set of judgment rules pre-set and stored within the system controller, used to assess whether the current outdoor environment is suitable for activating the ventilation module. These conditions are defined based on a comparison between outdoor environmental parameters and the internal state of the computer room—the core purpose of which is to ensure that the ventilation module is only allowed to activate when introducing outdoor air can effectively reduce the temperature of the computer room without adversely affecting the equipment inside the computer room.

[0039] In the medium temperature range, the ventilation module is activated or deactivated based on whether the preset ventilation conditions are met according to outdoor environmental parameters. This ensures that ventilation is activated only when the outdoor climate is suitable to utilize free cold sources for heat dissipation. In this way, while keeping the air conditioner off to reduce energy consumption, it effectively avoids the introduction of high temperature or high humidity air that may have an adverse effect on the internal environment of the computer room, thus achieving a balance between energy saving and reliability.

[0040] Based on any of the above embodiments, the outdoor environmental parameters include the external temperature of the computer room and the external relative humidity of the computer room. The step of determining whether the preset ventilation conditions are met based on the outdoor environmental parameters includes: The system determines whether the external temperature of the computer room is lower than the internal temperature of the computer room, whether the difference between the internal temperature of the computer room and the external temperature of the computer room is greater than or equal to a preset temperature difference threshold, and whether the external relative humidity of the computer room is less than or equal to a preset humidity threshold. If the external temperature of the computer room is lower than the internal temperature of the computer room, the difference is greater than or equal to the preset temperature difference threshold, and the external relative humidity of the computer room is less than or equal to the preset humidity threshold, then the preset ventilation conditions are determined to be met.

[0041] It should be noted that the external temperature of the computer room refers to the temperature value of the air outside the computer room monitored by the temperature sensing element in the outdoor environment sensor. The external relative humidity of the computer room refers to the relative humidity value of the air outside the computer room monitored by the humidity sensing element in the outdoor environment sensor. The preset temperature difference threshold is a pre-set critical value of temperature difference stored in the system controller. It is used to require that the external temperature of the computer room is not only lower than the internal temperature of the computer room, but the temperature difference between the two must also be sufficient to ensure that the introduced outdoor air has sufficient heat absorption capacity. The preset humidity threshold is a pre-set critical value of relative humidity stored in the system controller. It is used to limit the maximum humidity of the outdoor air that can be introduced to prevent high humidity air from entering the computer room and causing condensation on the surfaces of internal equipment or leading to a decrease in electrical insulation performance.

[0042] Understandably, the preset ventilation conditions comprehensively constrain the feasibility of ventilation in the outdoor environment from three dimensions: temperature effectiveness, temperature range, and humidity safety. Only when all three conditions are met simultaneously can it be determined that the outdoor air has sufficient heat absorption capacity without causing humidity hazards to the equipment inside the computer room. If any condition is not met—for example, the outdoor temperature is higher than the indoor temperature, the temperature difference is insufficient for effective heat absorption, or the outdoor air is too humid—the system will determine that the ventilation conditions are not met and keep the ventilation module closed to ensure that the introduction of ventilation operations will not worsen the thermal environment of the computer room or introduce safety hazards.

[0043] This invention sets three judgment conditions—outdoor temperature is lower than indoor temperature, temperature difference reaches a preset threshold, and humidity does not exceed a preset threshold—and requires all three conditions to be met simultaneously before ventilation is activated. This ensures that a cold source is introduced only when the outdoor air has sufficient cooling capacity and is free of moisture hazards. This fully utilizes free natural cold sources to achieve energy conservation, effectively avoids the intrusion of ineffective hot air or high-humidity air, ensures the safe and reliable operation of computer room equipment, and improves the system's adaptability to complex climates.

[0044] Based on any of the above embodiments, after controlling both the air conditioning module and the ventilation module to start operation if the internal temperature of the computer room is greater than the second threshold, the method further includes: Obtain the deviation between the internal temperature of the computer room and the preset target temperature; Based on the deviation value, the target operating frequency of the air conditioning module is calculated, and a corresponding frequency control signal is generated according to the target operating frequency; The frequency control signal is sent to the inverter of the air conditioning module so that the inverter outputs AC power of the corresponding frequency to drive the compressor of the air conditioning module to operate at the target operating frequency.

[0045] It should be noted that the preset target temperature refers to the desired temperature value inside the computer room, pre-set and stored in the system controller. This value is typically set within the optimal temperature range required for reliable operation of the communication equipment. The deviation value is the difference between the actual measured temperature inside the computer room and the preset target temperature. When the temperature inside the computer room is higher than the preset target temperature, the deviation value is positive, indicating that cooling is required. The larger the deviation value, the further the current temperature deviates from the target temperature, and the greater the required cooling capacity. The target operating frequency refers to the power frequency at which the inverter compressor in the air conditioning module should operate. This frequency determines the compressor's rotational speed, and thus the cooling capacity output of the air conditioning module—the higher the frequency, the faster the compressor speed, the greater the refrigerant circulation flow, and the greater the cooling capacity; the lower the frequency, the smaller the cooling capacity.

[0046] In practical implementation, the target operating frequency is calculated as follows: the deviation value is input into a preset control algorithm, which establishes a mapping relationship between the deviation value and the target operating frequency. When using a proportional-integral-derivative (PID) control algorithm, the system controller inputs the deviation value into three computational pathways: the proportional term output, which is proportional to the current deviation value and used for rapid response to the current temperature deviation; the integral term output, which is proportional to the cumulative deviation value over time and used to eliminate steady-state temperature errors; and the derivative term output, which is proportional to the rate of change of the deviation value and used to predict temperature change trends and perform proactive adjustments. The sum of these three outputs yields the total control output value, which is then converted into the target operating frequency value after range mapping.

[0047] In this embodiment of the invention, after the air conditioning module is started, the target operating frequency is calculated by obtaining the deviation value between the internal temperature of the computer room and the preset target temperature, and the inverter is controlled to drive the compressor to operate at the frequency. This realizes the dynamic and continuous adjustment of the cooling capacity of the air conditioning module according to the real-time heat load. When the temperature difference is large, the high-frequency operation is used to cool down quickly, and when the temperature difference is small, the frequency is automatically reduced to avoid over-cooling. While ensuring the temperature control accuracy, the energy consumption of the air conditioning operation is significantly reduced, and the system energy efficiency level is improved.

[0048] Figure 4 This is the second flowchart illustrating the collaborative control method of the outdoor communication equipment room management system provided by the present invention, as shown below. Figure 4 As shown, the cooperative control method further includes steps 105 to 107: Step 105: Obtain temperature change data of the computer room interior within a preset historical period; It should be noted that the preset historical period refers to a preset time interval preceding the current moment, typically in the hours or days, such as the past 6 hours, the past 24 hours, or the past 7 days. Temperature change data refers to multiple historical sampled values ​​of the computer room's internal temperature and their corresponding timestamps recorded by the system controller according to the sampling period within this preset historical period. This data reflects the evolution of the computer room's internal temperature over a longer time scale.

[0049] Step 106: Determine the cooling demand trend inside the computer room based on the temperature change data; It should be noted that the cooling demand trend refers to the direction of change in the demand for heat dissipation capacity within the computer room over time, specifically manifested as a continuous increase, a continuous decrease, or stabilization. This trend reflects the long-term evolution of the computer room's heat load and is an important basis for adjusting control parameters.

[0050] Step 107: Adjust the first threshold and / or the second threshold according to the cooling demand trend; wherein, when the cooling demand trend is continuously rising, the second threshold is lowered to start the air conditioning module in advance; when the cooling demand trend is continuously falling, the first threshold is raised to extend the duration of zero-power radiation heat dissipation by the infrared radiation cooling skin alone.

[0051] It is understandable that the first and second thresholds are two preset temperature boundary values ​​used in the system controller to divide the three temperature ranges. Adjusting the first and / or second thresholds allows the control strategy to adapt to changes in cooling demand.

[0052] In practical implementation, when the cooling demand trend is continuously increasing, the system controller subtracts a preset adjustment amount from the original second threshold to obtain a reduced second threshold. This reduced second threshold allows the air conditioning module to start earlier at lower temperatures, thus intervening in active cooling earlier to prevent temperature runaway. When the cooling demand trend is continuously decreasing, the system controller adds a preset adjustment amount to the original first threshold to obtain an increased first threshold. This increased first threshold allows the system to maintain a state of zero-power radiation heat dissipation solely through the skin at higher temperatures, thereby further extending the zero-power heat dissipation period and saving energy as cooling demand decreases.

[0053] This invention identifies long-term trends in cooling demand by acquiring historical temperature change data and adaptively adjusts a first threshold and / or a second threshold accordingly. When cooling demand continues to rise, the second threshold is lowered to activate the air conditioner earlier and prevent temperature runaway; when cooling demand continues to fall, the first threshold is raised to extend the zero-power radiative heat dissipation period. This mechanism enables the control strategy to be dynamically optimized with seasonal changes and load evolution, further tapping into energy-saving potential while ensuring equipment temperature safety, and improving the system's adaptability and energy efficiency throughout its entire lifecycle.

[0054] Based on any of the above embodiments, it further includes: Obtain real-time operating power consumption data of the communication equipment inside the outdoor communication equipment room, and / or obtain predicted load data of the communication equipment inside the outdoor communication equipment room; Calculate the predicted temperature change based on the real-time operating power consumption data and / or the predicted load data; Based on the predicted temperature change, predict the time when the temperature inside the computer room will reach the second threshold. When the arrival time is less than a preset time threshold, both the air conditioning module and the ventilation module are started.

[0055] It should be noted that communication equipment refers to electronic devices such as BBUs, servers, and switches installed inside outdoor communication equipment rooms that generate heat. The vast majority of their power consumption is ultimately converted into heat; therefore, power consumption data is a key parameter characterizing the source of heat load in the equipment room. Real-time operating power consumption data refers to the actual power consumption of the communication equipment at the current moment. This data reflects the current amount of heat generated by the equipment—the higher the power consumption, the greater the heat generation. The system controller can perceive the immediate status of the current heat load by monitoring this data in real time. Predicted load data refers to the expected power consumption of the communication equipment over a future period, predicted based on historical load patterns, service scheduling plans, or external triggering events. This data reflects the possible trend of heat generation changes in the communication equipment over a future period.

[0056] Understandably, the predicted temperature change refers to the magnitude by which the internal temperature of the computer room will rise or fall over a future period, based on the estimated heat output of the communication equipment. The system controller calculates the predicted temperature change based on real-time operating power consumption data and / or predicted load data, combined with the heat capacity parameters of the air and equipment within the computer room, as well as the current heat dissipation power of each cooling module. Based on the calculated predicted temperature change, the system controller estimates the time required for the internal temperature to reach the second threshold, using the difference between the current internal temperature and the second threshold, along with the predicted temperature change. A shorter arrival time indicates a more rapid temperature rise, requiring the system to intervene more quickly. The preset time threshold is a pre-set minimum response time used to determine whether early intervention is necessary—when the predicted arrival time is less than this preset time threshold, it indicates that waiting for the actual temperature to reach the second threshold before starting the air conditioning module will result in temperature overshoot due to control delay or equipment response time. At this time, the system controller starts the air conditioning and ventilation modules in advance, without waiting for the actual temperature inside the computer room to reach the second threshold. This allows the active cooling resources to be put into operation before the temperature reaches the second threshold, thereby effectively suppressing temperature overshoot and shortening the temperature recovery time.

[0057] This invention, through acquiring real-time power consumption and / or predicted load data of communication devices, predicts temperature change trends in advance and calculates the remaining time to reach a second threshold. When the prediction time is insufficient, it proactively activates the air conditioning and ventilation modules, achieving a control upgrade from "post-event response" to "feedforward prediction." This mechanism can proactively deploy cooling resources before a sudden load increase causes a rapid temperature rise, effectively suppressing temperature overshoot and avoiding temperature exceedances due to control delays. This improves the system's temperature control accuracy and equipment operational reliability under dynamic load scenarios.

[0058] Based on any of the above embodiments, it further includes: Get the preset safe temperature limit; Calculate the temperature difference between the internal temperature of the computer room and the preset safe upper temperature limit; When the temperature difference is less than or equal to a preset warning threshold, the temperature change data of the computer room interior within a preset historical period is obtained, and the current operating status information of the ventilation module and the air conditioning module is obtained. Based on the temperature change data, the operating status information, and the temperature difference, an early warning analysis report is generated; The early warning analysis report is sent to the operation and maintenance management platform so that the operation and maintenance management platform can display the early warning analysis report.

[0059] It should be noted that the preset safe temperature upper limit refers to the maximum permissible temperature inside the computer room, pre-set and stored in the system controller. This value is the critical temperature threshold for the safe operation of communication equipment, and its value is usually higher than the second threshold, serving as the final safety boundary of the thermal management system. The temperature difference refers to the gap between the actual measured temperature inside the computer room and the preset safe temperature upper limit, reflecting the remaining margin between the current temperature and the safety boundary—the smaller the difference, the closer the temperature is to the safe upper limit, and the higher the potential risk. The preset warning threshold is a pre-set temperature difference threshold used to determine how close to the safe upper limit to trigger an warning. Its value can be set comprehensively based on the equipment's temperature sensitivity and maintenance response time.

[0060] Understandably, temperature change data refers to multiple historical sampled values ​​of the computer room's internal temperature and their corresponding timestamps recorded by the system controller according to a sampling period within a preset historical time frame. This data reflects the evolution trajectory of the computer room's internal temperature over time. By analyzing the temperature change data, it can be determined whether the temperature is continuously rising, stabilizing, or has begun to decline. Operating status information refers to the operating parameters of the ventilation and air conditioning modules at the current moment, including at least the current operating mode of each module and its operating parameters when it is on (such as fan speed and compressor operating frequency). This information reflects the actual utilization of the system's various heat dissipation methods and is an important basis for judging whether the heat dissipation capacity is sufficient.

[0061] In its implementation, the system controller triggers an early warning process after determining that the temperature difference is less than or equal to a preset warning threshold. The system controller first reads temperature sampling records from its internal buffer for a preset historical period and calculates the rate of temperature change to determine the trend direction (rising, stable, or falling). Simultaneously, it reads the start / stop status and fan speed of the ventilation module, and the start / stop status and compressor operating frequency of the air conditioning module from its internal registers. Then, the system controller fills in and formats the temperature difference, temperature change data and trends, and operating status information according to a preset report template, generating an early warning analysis report. The report's data structure includes at least the following fields: report generation time, current room temperature, preset safe temperature upper limit, remaining temperature difference, temperature change trend, temperature change rate, ventilation module operating status, air conditioning module operating status, and risk warning information automatically generated based on the above data. The system controller sends the early warning analysis report to the operation and maintenance management platform through its communication interface. After receiving the report, the operation and maintenance management platform parses the data and presents the report content to the operation and maintenance personnel on the platform's front-end interface through pop-up prompts, alarm list displays, or real-time curve annotations. At the same time, it can trigger SMS or application push notifications on the platform side to remind the operation and maintenance personnel to check in time, so that the operation and maintenance personnel can remotely judge the risk level, locate the cause of the fault, and make corresponding operation and maintenance decisions based on the complete information in the report.

[0062] This invention automatically generates an early warning analysis report containing temperature change data, system operating status information, and remaining temperature difference when the temperature approaches the safe upper limit, and sends it to the operation and maintenance management platform. This enables operation and maintenance personnel to remotely know the high temperature risk in the computer room, understand the temperature evolution trend and the operating status of the heat dissipation module, and thus determine the risk level, preliminarily locate the cause of the fault, and make operation and maintenance preparations in advance without being on-site, which significantly improves the efficiency of operation and maintenance response and the accuracy of fault handling.
