Technical Field

[0002] Communication base stations generate significant heat during operation due to the numerous devices within them. Failure to dissipate heat promptly could cause these devices to malfunction. Base station equipment (such as the main equipment and power supplies) requires a stable operating temperature (typically 25°C ± 5°C). Base station air conditioners are key heat dissipation devices. Base station air conditioners typically utilize dual units, with active and standby units rotating in order to maintain cooling.

[0003] However, when the base station is in a high temperature or high load scenario, if the two air conditioners are still running in rotation (only one is working at this time) or the two air conditioners are not working together in time, the power consumption of the air conditioners will increase much more than the power consumption of working together in time, which will not save energy and will also lead to problems such as shortening the life of the air conditioners in the base station.

Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments.

[0039] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0040] The present invention provides a base station air conditioner and its control method, device, storage medium, and program product. The base station air conditioner is a dual air conditioner unit, that is, the base station is equipped with two air conditioners for cooling the base station. One of the two air conditioners is a main unit, and the other is a backup unit.

[0041] Base station air conditioning configuration composition:

[0042] A dual air conditioning system consists of two split-type air conditioners of the same model. For example, they support a wide operating temperature range of -15°C to 55°C. The indoor units are installed on both sides of the base station equipment cabinet, with the air outlets facing the heat dissipation area of ​​the main equipment (such as the BBU and power modules). The outdoor units are independently deployed in a ventilated area outside the base station, with a spacing of 1.5 meters or more to prevent air short-circuiting.

[0043] Sensing and data acquisition module:

[0044] Temperature monitoring unit: Deploy temperature sensors (such as PT1000 platinum resistance temperature sensors) at the main equipment air outlet (core monitoring point), the top and bottom of the main base station, and the air conditioning return air vent (auxiliary monitoring point). Monitoring the main equipment air outlet temperature reflects the heat dissipation status of the base station's main equipment (such as the BBU and power module). Monitoring the air conditioning return air vent temperature provides the base station ambient reference temperature, which is used to correct local deviations in air outlet data. Monitoring the base station top temperature indicates hot air accumulation, preventing overheating that could cause equipment throttling. Monitoring the base station bottom temperature indicates cold air distribution, preventing condensation caused by overcooling. Data is sampled at a frequency of, for example, 10 seconds and transmitted to the controller via the RS-485 bus.

[0045] Power consumption monitoring unit: A current sensor (e.g., Hall effect current sensor model: ACS712-30A, accuracy ±1.5%) can be used to collect the total current of the base station main equipment in real time, and linked with the smart meter to achieve minute-level energy consumption statistics.

[0046] Third, control center:

[0047] The core hardware can be, for example, an ARM Cortex-M7-based embedded controller (300MHz, 512KB RAM) equipped with a real-time operating system (FreeRTOS); the communication module is a 4G DTU for remote monitoring, supporting the MQTT protocol for interaction with the cloud platform, and a local CAN bus connecting the air conditioning unit and sensors to ensure that the command response delay is less than 200ms.

[0048] The present invention provides a control method for a base station air conditioner. The base station air conditioner is a dual air conditioner unit, that is, the base station is equipped with two air conditioners for cooling the base station. Of the two air conditioners, one is a main unit and the other is a backup unit.

[0049] Figure 1 It is a method diagram of an embodiment of a base station air conditioner control method provided by the present invention.

[0050] like Figure 1 As shown, according to one embodiment of the present invention, the control method at least includes step S110, step S120 and step S130.

[0051] Step S110 : After the base station air conditioner is started in a single-machine rotation mode, the ambient temperature of the environment where the base station is located and / or the current power consumption of the equipment of the base station are collected.

[0052] Specifically, after system initialization, the single-machine rotation mode is initiated. The single-machine rotation mode involves alternating operation of the primary and backup machines. For example, a dual air conditioning unit may include air conditioners A and B, with air conditioners A serving as the primary and B serving as the backup. The ambient temperature of the base station's environment (specifically, the indoor ambient temperature) and the current power consumption of the base station's equipment are collected in real time. The ambient temperature can be collected using a temperature collection device (e.g., a temperature sensor) located in the environment. The current power consumption of the base station's equipment can be collected using an electrical parameter collection device (e.g., a power meter or energy meter). For example, the power meter or energy meter measures the equipment's power consumption in real time to obtain actual power consumption data during operation.

[0053] Step S120 , determining whether the ambient temperature is greater than or equal to a first preset temperature threshold, and / or whether the device power consumption is greater than or equal to a first preset power consumption threshold.

[0054] In one specific embodiment, the first preset power consumption threshold is equal to a first preset percentage of the rated cooling capacity of the single air conditioner. The first preset percentage is, for example, 80%. That is, if the rated cooling capacity of the single air conditioner is Q0, then the first preset power consumption threshold is equal to 80% Q0. For example, if Q0 = 15 kW, then the first preset power consumption threshold is 12 kW.

[0055] Step S130: If it is determined that the ambient temperature is greater than or equal to a first preset temperature threshold, and / or the device power consumption is greater than or equal to a first preset power consumption threshold, a dual-machine co-operation mode is executed.

[0056] The dual-unit co-operation mode is a mode in which both air conditioners in the dual air conditioning unit operate simultaneously. For example, if the first preset temperature threshold is 35°C and the first preset power consumption threshold is 12kW, then if T ≥ 35°C or Q ≥ 12kW, the dual-unit co-operation mode is implemented. Air conditioners A and B are started simultaneously; otherwise, the single-unit rotation mode is maintained.

[0057] In dual-unit operation mode, a PID algorithm can be used to adjust the compressor speed based on the deviation between the indoor ambient temperature and the target temperature, keeping the deviation between the indoor ambient temperature and the target temperature within ±1°C. In single-unit rotation mode, the main unit is switched every preset period. For example, the main unit is switched every 12 hours, that is, the main unit switches from air conditioner A to air conditioner B, or from air conditioner B to air conditioner A.

[0058] Preferably, the need to adjust the first preset temperature threshold is determined based on the ambient humidity. Specifically, a humidity compensation factor is introduced to dynamically adjust the first preset temperature threshold. When the ambient humidity exceeds the preset humidity threshold, the first preset temperature threshold is adjusted downward by a preset value. For example, when the humidity exceeds 70% (the preset humidity threshold), the first preset temperature threshold is adjusted downward by 2°C to 33°C.

[0059] Preferably, when dual-unit operation is in progress, cooling capacity is dynamically allocated based on the performance differences of the air conditioners. Specifically, when the primary unit (air conditioner A) and the secondary unit (air conditioner B) of the dual air conditioner set are started simultaneously, the cooling capacity of the primary unit and the secondary unit of the dual air conditioner set is allocated according to the following formula:

[0060] ;

[0061] ;

[0062] Among them, Q represents the current equipment power consumption of the base station, that is, the total cooling capacity of the dual air-conditioning units, Q A Indicates the cooling capacity of the main unit, Q Brepresents the cooling capacity of the standby unit. K is the preset distribution coefficient, which is determined based on the operating time and aging of the primary unit (air conditioner A) and the standby unit (air conditioner B). For example, the value of K ranges from 1 ≤ K ≤ 2. The primary unit (air conditioner A) bears a heavier load, has a longer operating time than the standby unit (air conditioner B), and ages faster. As air conditioner A continues to operate and age, its performance degrades, and the value of K changes dynamically.

[0063] In one embodiment, the allocation coefficient decreases as the total operating time of the host increases. For each increase in the total operating time of the host, the allocation coefficient decreases by a preset value until it reaches a preset minimum value. For example, initially, K = 2, the preset minimum K value is 1.2, and N is the total operating time of the host. Assuming that the allocation coefficient decreases by 0.16 for each additional year of operating time, then when N = 0, K = 2. Over time, the K value gradually decreases, such that when N = 1, K = 1.84, when N = 2, K = 1.68, ..., when N = 5, K = 1.2.

[0064] Figure 2 It is a method diagram of another embodiment of the base station air conditioner control method provided by the present invention.

[0065] like Figure 2 As shown, according to another embodiment of the present invention, the control method further includes step S140, step S150 and step S160.

[0066] Step S140: After executing the dual-machine co-operation mode, the ambient temperature of the environment where the base station is located and the current device power consumption of the base station are collected again.

[0067] Step S150 , determining whether the ambient temperature is less than or equal to a second preset temperature threshold, and whether the device power consumption is less than or equal to a second preset power consumption threshold.

[0068] In one specific embodiment, the second preset power consumption threshold is equal to a second preset percentage of the rated cooling capacity of the single air conditioner. The second preset percentage is, for example, 50%. That is, if the rated cooling capacity of the single air conditioner is Q0, then the second preset power consumption threshold is equal to 50% Q0. For example, if Q0 = 15 kW, then the second preset power consumption threshold is 7.5 kW.

[0069] Step S160: If it is determined that the ambient temperature is less than or equal to the second preset temperature threshold, and the device power consumption is less than or equal to the second preset power consumption threshold, the single-machine rotation mode is executed.

[0070] Specifically, when the two air conditioners of the dual air-conditioning unit are running at the same time, it is monitored whether the exit condition is met, that is, it is judged that the ambient temperature is less than or equal to the second preset temperature threshold, and the device power consumption is less than or equal to the second preset power consumption threshold. When it is judged that the ambient temperature is less than or equal to the second preset temperature threshold, and the device power consumption is less than or equal to the second preset power consumption threshold, it switches back to the single-machine rotation mode.

[0071] Preferably, if the ambient temperature is determined to be less than or equal to a second preset temperature threshold and the device power consumption is less than or equal to a second preset power consumption threshold, the system switches back to the standalone rotation mode after a preset delay. For example, when T ≤ 25°C and Q ≤ 7.5kW (50% Q0), the system switches back to the standalone rotation mode.

[0072] Figure 3 It is a method diagram of another embodiment of the base station air conditioner control method provided by the present invention.

[0073] like Figure 2 As shown, according to another embodiment of the present invention, the control method further includes step S170, step S180 and step S190.

[0074] Step S170 , obtaining the equipment power consumption of the base station, the ambient temperature of the environment in which the base station is located, and the network traffic data of the base station within a first preset time period in the past.

[0075] Specifically, the ambient temperature (°C) of the environment and the network traffic data (Gbps) of the base station in the past period of time are obtained. For example, the device power consumption, ambient temperature, and network traffic data of the base station in the past 2 hours are obtained.

[0076] Step S180: Input the acquired data of the equipment power consumption of the base station, the ambient temperature of the environment and the network traffic of the base station within the first preset time into a preset prediction model to predict the equipment power consumption of the base station within the second preset time in the future.

[0077] The prediction model can be, for example, an LSTM neural network model that can predict future data based on past data. When building the LSTM model, the base station's device load (i.e., device power consumption), ambient temperature, and network traffic data can be recorded at preset intervals (e.g., 5 minutes) to train the LSTM neural network model.

[0078] By inputting the real-time data on the base station's device power consumption, ambient temperature, and network traffic over a first preset period of time into a trained prediction model, the base station's device power consumption over a second preset period of time can be predicted. For example, by analyzing the base station's load (device power consumption), temperature fluctuations, and network traffic over the past two hours, the base station's load over the next hour can be predicted.

[0079] Step S190: If it is predicted that the device power consumption of the base station will reach a third preset power consumption threshold within a second preset time in the future, the dual-machine joint operation mode is started in advance before the moment when the device power consumption reaches the third preset power consumption threshold, wherein the dual-machine joint operation mode is started in advance of the third preset time.

[0080] For example, if the predicted device power consumption Q ≥ 75% Q0, it is marked as a high load warning, and the dual machines are started to preheat 10 minutes in advance to prepare for the formal implementation of the dual-machine joint operation mode.

[0081] Among them, when the dual-machine joint operation mode is started in advance, the cooling capacity of each air conditioner (main unit and standby unit) when executing the dual-machine joint operation mode is first allocated (allocated according to the formula for allocating the cooling capacity of the main unit and standby unit mentioned above), and then the cooling capacity of the currently running air conditioner is reduced to the third preset percentage of the allocated cooling capacity, and the air conditioner that is not currently running is controlled to operate at the fourth preset percentage of the allocated cooling capacity. Thereafter, the cooling capacity of each air conditioner is increased by the preset percentage every fourth preset time until the allocated cooling capacity is reached.

[0082] For example, after air conditioner A is turned on to 50% load (cooling capacity), and air conditioner B is turned on to 30% load (cooling capacity), the load is increased by 10% every 2 minutes. By the time it really gets busy, the air conditioners are ready to run at full speed.

[0083] To clearly illustrate the technical solution of the present invention, the execution flow of the base station air conditioner control method provided by the present invention is described below with reference to a specific embodiment.

[0084] Figure 4 FIG. 1 is a method diagram of a specific embodiment of the base station air conditioner control method provided by the present invention. Figure 4 As shown, the base station air conditioner starts in single-machine rotation mode and monitors real-time parameters within the base station: temperature T, equipment power consumption Q, and the rated cooling capacity of each air conditioner is set to Q0. When T ≥ 35°C or Q ≥ 80% Q0 is met, the dual-machine joint operation mode is started and the real-time parameters are continuously monitored. When T ≤ 25°C and Q ≤ 50% Q0 are met at the same time, the dual-machine joint operation mode is exited and switched to single-machine rotation mode, with rotation every 12 hours.

[0085] The present invention also provides a control device for a base station air conditioner. The base station air conditioner is a dual air conditioner unit, that is, the base station is equipped with two air conditioners for cooling the base station. Of the two air conditioners, one is a main unit and the other is a backup unit.

[0086] Figure 5 This is a structural block diagram of an embodiment of the base station air conditioner control device provided by the present invention. Figure 5As shown, the control device 100 includes: a collection unit 110 , a judgment unit 120 and an execution unit 130 .

[0087] The collecting unit 110 is configured to collect the ambient temperature of the environment in which the base station is located and / or the current power consumption of the equipment of the base station after the base station air conditioner is started in a single-machine rotation mode.

[0088] Specifically, after system initialization, the single-machine rotation mode is initiated. The single-machine rotation mode involves alternating operation of the primary and backup machines. For example, a dual air conditioning unit may include air conditioners A and B, with air conditioners A serving as the primary and B serving as the backup. The ambient temperature of the base station's environment (specifically, the indoor ambient temperature) and the current power consumption of the base station's equipment are collected in real time. The ambient temperature can be collected using a temperature collection device (e.g., a temperature sensor) located in the environment. The current power consumption of the base station's equipment can be collected using an electrical parameter collection device (e.g., a power meter or energy meter). For example, the power meter or energy meter measures the equipment's power consumption in real time to obtain actual power consumption data during operation.

[0089] The judging unit 120 is configured to judge whether the ambient temperature is greater than or equal to a first preset temperature threshold, and / or whether the device power consumption is greater than or equal to a first preset power consumption threshold.

[0090] In one specific embodiment, the first preset power consumption threshold is equal to a first preset percentage of the rated cooling capacity of the single air conditioner. The first preset percentage is, for example, 80%. That is, if the rated cooling capacity of the single air conditioner is Q0, then the first preset power consumption threshold is equal to 80% Q0. For example, if Q0 = 15 kW, then the first preset power consumption threshold is 12 kW.

[0091] The execution unit 130 is configured to execute the dual-machine co-operation mode if the judgment unit determines that the ambient temperature is greater than or equal to a first preset temperature threshold, and / or the device power consumption is greater than or equal to a first preset power consumption threshold.

[0092] The dual-unit co-operation mode is a mode in which both air conditioners in the dual air conditioning unit operate simultaneously. For example, if the first preset temperature threshold is 35°C and the first preset power consumption threshold is 12kW, then if T ≥ 35°C or Q ≥ 12kW, the dual-unit co-operation mode is implemented. Air conditioners A and B are started simultaneously; otherwise, the single-unit rotation mode is maintained.

[0093] In dual-unit operation mode, a PID algorithm can be used to adjust the compressor speed based on the deviation between the indoor ambient temperature and the target temperature, keeping the deviation between the indoor ambient temperature and the target temperature within ±1°C. In single-unit rotation mode, the main unit is switched every preset period. For example, the main unit is switched every 12 hours, that is, the main unit switches from air conditioner A to air conditioner B, or from air conditioner B to air conditioner A.

[0094] Preferably, the apparatus 100 further includes an adjustment unit (not shown) configured to determine whether the first preset temperature threshold needs to be adjusted based on the ambient humidity. Specifically, a humidity compensation factor is introduced to dynamically adjust the first preset temperature threshold. When the ambient humidity exceeds the preset humidity threshold, the first preset temperature threshold is adjusted downward by a preset value. For example, when the humidity exceeds 70% (the preset humidity threshold), the first preset temperature threshold is adjusted downward by 2°C to 33°C.

[0095] Preferably, the execution unit 130 dynamically allocates cooling capacity based on the performance differences of the air conditioners when executing the dual-unit operation mode. Specifically, when the master unit (air conditioner A) and the backup unit (air conditioner B) of the dual air conditioner set are started simultaneously, the cooling capacity of the master unit and the backup unit of the dual air conditioner set is allocated according to the following formula. That is, the cooling capacity of the master unit (air conditioner A) and the backup unit (air conditioner B) is allocated as follows:

[0096] ;

[0097] ;

[0098] Among them, Q represents the current equipment power consumption of the base station, that is, the total cooling capacity of the dual air-conditioning units, Q A Indicates the cooling capacity of the main unit, Q B represents the cooling capacity of the standby unit. K is the preset distribution coefficient, which is determined based on the operating time and aging of the primary unit (air conditioner A) and the standby unit (air conditioner B). For example, the value of K ranges from 1 ≤ K ≤ 2. The primary unit (air conditioner A) bears a heavier load, has a longer operating time than the standby unit (air conditioner B), and ages faster. As air conditioner A continues to operate and age, its performance degrades, and the value of K changes dynamically.

[0099] In one embodiment, the allocation coefficient decreases as the total operating time of the host increases. For each increase in the total operating time of the host, the allocation coefficient decreases by a preset value until it reaches a preset minimum value. For example, initially, K = 2, the preset minimum K value is 1.2, and N is the total operating time of the host. Assuming that the allocation coefficient decreases by 0.16 for each additional year of operating time, then when N = 0, K = 2. Over time, the K value gradually decreases, such that when N = 1, K = 1.84, when N = 2, K = 1.68, ..., when N = 5, K = 1.2.

[0100] Optionally, the collection unit 110 is further used to: after executing the dual-machine co-operation mode, collect the ambient temperature of the environment in which the base station is located and / or the current device power consumption of the base station; the judgment unit 120 is further used to: judge whether the ambient temperature is less than or equal to a second preset temperature threshold, and / or whether the device power consumption is less than or equal to a second preset power consumption threshold; the execution unit 130 is further used to: if the judgment unit 120 judges that the ambient temperature is less than or equal to the second preset temperature threshold, and / or the device power consumption is less than or equal to the second preset power consumption threshold, then execute the single-machine rotation mode.

[0101] In one specific embodiment, the second preset power consumption threshold is equal to a second preset percentage of the rated cooling capacity of the single air conditioner. The second preset percentage is, for example, 50%. That is, if the rated cooling capacity of the single air conditioner is Q0, then the second preset power consumption threshold is equal to 50% Q0. For example, if Q0 = 15 kW, then the second preset power consumption threshold is 7.5 kW.

[0102] When the two air conditioners of the dual air-conditioning unit are running at the same time, monitor whether the exit condition is met, that is, judge whether the ambient temperature is less than or equal to the second preset temperature threshold, and the device power consumption is less than or equal to the second preset power consumption threshold. When it is judged that the ambient temperature is less than or equal to the second preset temperature threshold and the device power consumption is less than or equal to the second preset power consumption threshold, switch back to the single-machine rotation mode.

[0103] Preferably, if the ambient temperature is determined to be less than or equal to a second preset temperature threshold and the device power consumption is less than or equal to a second preset power consumption threshold, the system switches back to the standalone rotation mode after a preset delay. For example, when T ≤ 25°C and Q ≤ 7.5kW (50% Q0), the system switches back to the standalone rotation mode.

[0104] Figure 6 FIG. 1 is a structural block diagram of another embodiment of the base station air conditioner control device provided by the present invention. Figure 6 As shown, the control device 100 further includes: an acquisition unit 170 and a prediction unit 180 .

[0105] The acquisition unit 170 is configured to acquire the device power consumption of the base station, the ambient temperature of the environment in which the base station is located, and the network traffic data of the base station within a first preset time period in the past.

[0106] Specifically, the ambient temperature (°C) of the environment and the network traffic data (Gbps) of the base station in the past period of time are obtained. For example, the device power consumption, ambient temperature, and network traffic data of the base station in the past 2 hours are obtained.

[0107] The prediction unit 180 is used to input the equipment power consumption of the base station, the ambient temperature of the environment and the network traffic data of the base station within the past first preset time obtained by the acquisition unit into a preset prediction model to predict the equipment power consumption of the base station within the future second preset time.

[0108] The prediction model can be, for example, an LSTM neural network model that can predict future data based on past data. When building the LSTM model, the base station's device load (i.e., device power consumption), ambient temperature, and network traffic data can be recorded at preset intervals (e.g., 5 minutes) to train the LSTM neural network model.

[0109] By inputting the real-time data on the base station's device power consumption, ambient temperature, and network traffic over a first preset period of time into a trained prediction model, the base station's device power consumption over a second preset period of time can be predicted. For example, by analyzing the base station's load (device power consumption), temperature fluctuations, and network traffic over the past two hours, the base station's load over the next hour can be predicted.

[0110] The execution unit 130 is further configured to: if the prediction unit 180 predicts that the device power consumption of the base station will reach a third preset power consumption threshold within a second preset time in the future, start the dual-machine joint operation mode in advance before the moment when the device power consumption reaches the third preset power consumption threshold, wherein the dual-machine joint operation mode is started in advance of the third preset time.

[0111] For example, if the predicted device power consumption Q ≥ 75% Q0, it is marked as a high load warning, and the dual machines are started to preheat 10 minutes in advance to prepare for the formal implementation of the dual-machine joint operation mode.

[0112] Among them, when the dual-machine co-operation mode is started in advance, the execution unit 130 first allocates the cooling capacity of each air conditioner (main unit and backup unit) when the dual-machine co-operation mode is executed (allocated according to the formula for allocating the cooling capacity of the main unit and backup unit mentioned above), and then reduces the cooling capacity of the currently running air conditioner to a third preset percentage of the allocated cooling capacity, and controls the currently non-running air conditioner to operate at a fourth preset percentage of the allocated cooling capacity, and then increases the cooling capacity of each air conditioner by a preset percentage every fourth preset time until the allocated cooling capacity is reached.

[0113] For example, after air conditioner A is turned on to 50% load (cooling capacity), and air conditioner B is turned on to 30% load (cooling capacity), the load is increased by 10% every 2 minutes. By the time it really gets busy, the air conditioners are ready to run at full speed.

[0114] The present invention also provides a storage medium corresponding to the control method of the base station air conditioner, on which a computer program is stored. When the computer program is executed by a processor, the steps of any of the above methods are implemented.

[0115] The present invention also provides an air conditioner corresponding to the control method of the base station air conditioner, comprising a processor, a memory, and a computer program stored in the memory and executable on the processor, wherein the processor implements the steps of any of the aforementioned methods when executing the computer program.

[0117] The present invention also provides a computer program product corresponding to the base station air conditioner control method, including a computer program, which implements the steps of any of the aforementioned methods when executed by a processor.

[0118] Accordingly, the solution provided by the present invention can automatically trigger switching to a mode in which two air conditioners work together when it is detected that the base station is in a high temperature or high load scenario, thereby greatly reducing the energy consumption of the base station air conditioner.

[0119] The solution provided by the present invention takes into account the situation of high humidity environment and dynamically adjusts the temperature threshold that triggers switching to dual-machine mode according to the ambient humidity, so that the air conditioning output capacity can better match the heat load in the base station.

[0120] The solution provided by the present invention can dynamically distribute the load according to the performance differences of air conditioners in a dual-machine co-operation mode, thereby improving the overall COP.

[0121] The solution provided by the present invention predicts the load in the future. If it is predicted that the load will reach a certain threshold within a period of time, the dual-machine preheating is started in advance to prepare for the formal implementation of the dual-machine joint operation mode.
