Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to a communication control method, device, air conditioning equipment and storage medium for a device. Background Technology

[0002] With the increasing application of IoT technology in the smart home field, smart air conditioners with remote connectivity are now commonly equipped with 4G communication modules to enable remote monitoring, online fault diagnosis, and energy efficiency management. In this application model, to ensure stable network connectivity in various complex environments, existing smart air conditioners typically set their 4G communication modules to operate at a fixed transmission power.

[0003] However, the actual operating state and communication needs of a device are not constant. This often leads to a mismatch between the transmission power of the 4G communication module and the device's operating state, affecting its efficient operation. For example, when the device is in a low-activity or standby state, the amount of data to be transmitted is small and the real-time requirements are low. If the communication module still operates at high power, it will result in unnecessary power consumption, shortening the battery life of the built-in power supply or increasing the overall standby power consumption. Conversely, when the device enters a high-activity state and needs to perform large amounts of data uploads, real-time control, or high-definition streaming media transmission, a fixed transmission power may not be able to guarantee the stability and timeliness of data throughput, affecting the reliability of core functions.

[0030] To address the technical problem in existing air conditioning equipment where the communication module operates at a fixed transmission power, leading to a mismatch between the communication module's transmission power and the equipment's operating status, thus affecting the equipment's efficient operation, this application provides a communication control method. This method establishes a linkage between the air conditioner's operating status and communication parameters, dynamically adapting the communication parameters of the air conditioning equipment's wireless communication module to the equipment's load, fundamentally balancing energy-saving requirements and communication reliability. Simultaneously, by using the air conditioner's own operating load as the core basis for adjusting communication parameters, communication control can be more closely aligned with the actual operating needs of the air conditioner without additional complex hardware modifications.

This enhances the matching between the communication module's transmission power and the equipment's operating status, thereby achieving synergistic optimization of the air conditioning equipment's communication reliability and overall energy efficiency.

[0031] The communication control method of the device provided in this application will be further explained below with reference to the accompanying drawings and specific embodiments. The embodiments do not constitute a limitation on the embodiments of this application.

[0032] See Figure 1 This is a flowchart illustrating an embodiment of a communication control method for a device provided in this application. As one embodiment, Figure 1 The illustrated process can be applied to air conditioning equipment, which can transmit data via a wireless communication module. For example... Figure 1 As shown, the process may include the following steps: Step 101: Obtain the current running load information.

[0033] The aforementioned load information refers to information related to the load operation of air conditioning equipment, which can be used to quantitatively reflect the current operating load level of the air conditioner.

[0034] In this step, in order to determine its current operating status, the air conditioning equipment can obtain the current operating load information and use this load information to quantify the current load status of the air conditioning equipment.

[0035] In one embodiment, the air conditioning device can collect operating parameters of multiple currently operating functional modules. Then, based on these operating parameters, the currently operating load information can be determined. These operating parameters may include, but are not limited to, the input power, operating current, and rotational speed of the functional modules.

[0036] As for how the aforementioned load information was obtained, it will be explained below. Figure 2 The process shown will be explained in detail here.

[0037] Step 102: Determine the target communication parameters of the wireless communication module based on the above load information.

[0038] Step 103: Control the wireless communication module to operate according to the target communication parameters.

[0039] The following provides a unified explanation of steps 102 and 103: The aforementioned wireless communication module refers to a data transmission component (such as a 4G module) equipped in a smart air conditioner, used to realize IoT functions such as remote monitoring, fault diagnosis, and energy efficiency management. In this application, the transmit and receive power can be adaptively adjusted according to the air conditioner's operating load information to balance communication stability and energy consumption.

[0040] The aforementioned target communication parameters refer to the parameters that the wireless communication module needs to operate according to the load information, which may include, but are not limited to, the transmit power and receive sensitivity of the wireless communication module.

[0041] In this step, to ensure that the communication parameters of the wireless communication module match the operating status of the air conditioning equipment, the air conditioning equipment, after obtaining the current operating load information, can determine the target communication parameters of the wireless communication module based on this load information. Then, the wireless communication module can be controlled to operate according to the aforementioned target communication parameters.

[0042] In one embodiment, in order to comprehensively summarize load information of multiple different levels, different load levels can be pre-divided in this application, and a communication parameter of a wireless communication module can be assigned to each load level.

[0043] Based on this, the air conditioning equipment can pre-store the correlation between the above-mentioned classification rules, load levels, and communication parameters. Upon obtaining the load information, it can determine the target load level to which the load information belongs based on the classification rules. Then, the communication parameters corresponding to the target load level can be determined as the target communication parameters for the wireless communication module.

[0044] The technical solution provided in this application obtains the current operating load information, determines the target communication parameters of the wireless communication module based on the load information, and controls the wireless communication module to operate according to the target communication parameters. This technical solution establishes a linkage between the air conditioner's operating status and communication parameters, dynamically adapting the communication parameters of the air conditioner's wireless communication module to the load of the air conditioner, fundamentally balancing energy-saving requirements and communication reliability. Simultaneously, by using the air conditioner's own operating load as the core basis for adjusting communication parameters, communication control can be more closely aligned with the actual operating needs of the air conditioner without additional complex hardware modifications. This not only significantly reduces communication energy consumption during standby and low-frequency operation but also improves data transmission stability during high-frequency operation, thereby enhancing the matching between the transmission power of the communication module and the operating status of the air conditioner, ultimately achieving synergistic optimization of the air conditioner's communication reliability and overall energy efficiency.

[0045] See Figure 2 This is a flowchart illustrating an embodiment of a communication control method for a device provided in this application. Figure 2 The process shown is in Figure 1 Based on the illustrated process, the specific method for obtaining the currently running load information is described. For example... Figure 2 As shown, the process may include the following steps: Step 201: Obtain the module operation parameters of at least two currently running functional modules.

[0046] The aforementioned functional modules refer to the core components (such as compressors and indoor / outdoor fans) in air conditioning equipment that participate in core operating functions such as cooling and heating. Their operating parameters (such as frequency) can be collected and provide data support for load information calculation, which is the basis for realizing adaptive power adjustment of 4G modules.

[0047] The above-mentioned module operating parameters refer to the relevant parameters of the above-mentioned functional modules in actual operation, which may include, but are not limited to: operating frequency, input power, operating current, etc.

[0048] In this step, since the load of the air conditioning equipment is closely related to the operation of the functional modules within the air conditioning equipment, in order to accurately and comprehensively obtain the current operating load information, the air conditioning equipment can obtain the module operating parameters of at least two currently operating functional modules.

[0049] As an optional implementation, the air conditioning device may include an air conditioning motherboard and a wireless module. The air conditioning motherboard may include a main control unit and multiple functional modules, and the wireless module may include a wireless communication module and a control unit.

[0050] Based on this, the air conditioner main control unit can establish a real-time data link with the functional module through the CAN (Controller Area Network) communication interface, while the built-in operating parameter detection circuit of the functional module can capture its corresponding module operating parameters (such as operating frequency) in real time and send the module operating parameters to the control unit.

[0051] Subsequently, the aforementioned control unit can act as the execution subject in this application embodiment to obtain the module operation parameters of each of the multiple functional modules.

[0052] As an exemplary implementation, the aforementioned functional module may include a thermal drive module and an airflow drive module. The thermal drive module refers to the core functional module in an air conditioning unit responsible for realizing the core thermal cycle of cooling / heating, such as a compressor. The airflow drive module refers to the functional module in an air conditioning unit responsible for promoting indoor and outdoor airflow to transfer heat, such as the indoor / outdoor fans of the air conditioning unit.

[0053] Based on this, the air conditioning equipment can obtain the first module operating frequency of the aforementioned heat-driven module and the second module operating frequency of the airflow-driven module. Then, the first module operating frequency can be determined as the module operating frequency of the heat-driven module, and the second module operating frequency can be determined as the module operating frequency of the airflow-driven module.

[0054] Step 202: Determine the load factor of the current operation based on at least two module operating parameters.

[0055] Step 203: Determine the above load coefficient as the current operating load information.

[0056] The following provides a unified explanation of steps 202 and 203: The aforementioned load factor refers to a parameter value used to quantify the current load level of the air conditioning equipment.

[0057] In this step, after acquiring the module operating parameters of at least two functional modules, the air conditioning equipment can determine the current operating load factor based on these parameters. This load factor can then be used as the current operating load information for the air conditioning equipment.

[0058] In one embodiment, the maximum operating parameters of each functional module can be determined. The maximum operating parameters refer to the highest operating parameter values ​​that the functional module can achieve under design or rated conditions (e.g., when the functional modules are a compressor and a fan, and the module operating parameters are module operating power, the maximum operating frequency of the compressor is 120Hz and the maximum operating frequency of the fan is 80Hz).

[0059] As an optional implementation, the aforementioned functional modules may include a heat-driven module and an airflow-driven module. Based on this, the air conditioning equipment can obtain the maximum operating parameters of the heat-driven module and the maximum operating parameters of the airflow-driven module.

[0060] Then, for each functional module, the ratio between the module's operating parameters and the maximum operating parameters can be determined to obtain the module parameter ratio.

[0061] As an optional implementation, the above-mentioned module operating parameters can be the module operating frequency of the functional module. Based on this, the air conditioning equipment can obtain the module operating frequency of each functional module and determine the module operating frequency of each functional module as the module operating parameter of the corresponding functional module.

[0062] Finally, the weighted fusion of multiple module parameter ratios yields the load coefficient. The weight value for each functional module can be obtained based on the historical load information of the air conditioning equipment and the historical communication parameters of the wireless communication module. This historical load information and historical communication parameters can be historical data obtained from the air conditioning equipment's operation within a preset time period, such as the first 7 days after initial installation and operation.

[0063] As an optional implementation, the weight values ​​of each functional module during the load operation of the air conditioning equipment can be trained based on the historical load information of the air conditioning equipment and the historical communication parameters of the wireless communication module. Then, the module parameter ratio corresponding to each functional module can be multiplied by its corresponding weight value to obtain the module load coefficient. Finally, the load coefficients of multiple modules are summed to obtain the overall load coefficient.

[0064] In one embodiment, the functional module may include a thermal drive module and an airflow drive module, and the module operating parameters may be the first module operating frequency of the thermal drive module and the second module operating frequency of the airflow drive module, respectively.

[0065] Based on this, the first maximum operating frequency of the thermal drive module and the second maximum operating frequency of the airflow drive module can be obtained.

[0066] Then, for the thermal drive module, the ratio between the first module operating frequency of the thermal drive module and its corresponding first maximum operating frequency can be determined to obtain the first module parameter ratio.

[0067] At the same time, for the airflow driven module, the ratio between the second module operating frequency of the airflow driven module and its corresponding second maximum operating frequency can be determined to obtain the second module parameter ratio.

[0068] Finally, the first weight value corresponding to the heat-driven module and the second weight value corresponding to the airflow-driven module can be determined. The first module parameter ratio is multiplied by the first weight value to obtain a first product, and the second module parameter ratio is multiplied by the second weight value to obtain a second product. Then, the first product and the second product can be added together to obtain the load factor of the air conditioning equipment.

[0069] Since the thermal drive module is the main driving force for the operation of the air conditioning equipment, the weight value corresponding to the thermal drive module is greater than the preset weight threshold, while the weight value corresponding to the airflow drive module is less than the weight threshold. For example, the weight threshold can be 0.5, the weight value corresponding to the thermal drive module can be 0.7, and the weight value corresponding to the airflow drive module can be 0.3.

[0070] The technical solution provided in this application embodiment obtains the module operation parameters of at least two currently running functional modules, determines the load coefficient of the current operation based on the at least two module operation parameters, and determines the load coefficient as the load information of the current operation. This technical solution, through the fusion and acquisition of operating parameters from multiple modules, comprehensively covers the operating status of the core load (e.g., heat-driven) and auxiliary load (e.g., airflow-driven) of the air conditioner, avoiding power adjustment deviations caused by misjudgment of a single parameter, and making load quantification more consistent with the actual operating conditions of the air conditioner. At the same time, through the quantitative calculation of load coefficients, the dispersed module operating parameters are transformed into unified load evaluation indicators, providing a scientific and quantifiable core basis for the precise adjustment of the communication operating parameters of subsequent wireless communication modules, solving the core pain points of "excessive energy consumption at low loads and unstable communication at high loads" in the traditional fixed power operation mode. Furthermore, this solution highlights the dominant role of core modules such as compressors in the load (reflected through weight allocation), while also taking into account the operating influence of auxiliary modules such as fans. The resulting load information can dynamically track changes in the air conditioner's operating status, laying a precise foundation for the subsequent linkage adjustment of "load level - power level", ultimately achieving synergistic optimization of communication reliability and overall energy efficiency, without the need for additional complex hardware, and possessing strong practicality and economy. Thus, it achieves a more comprehensive and accurate determination of the current operating load information of the air conditioning equipment.

[0071] See Figure 3 This is a flowchart illustrating an embodiment of a communication control method for a device provided in this application. Figure 3 The process shown is in Figure 1 Based on the illustrated process, the specific steps for determining the target communication parameters of the wireless communication module according to the load information are described. For example... Figure 3 As shown, the process may include the following steps: Step 301: Determine the target load level to which the load information belongs from a set of preset load levels.

[0072] The aforementioned load levels refer to pre-defined levels used to characterize different load levels of air conditioning equipment operation.

[0073] In this step, in order to comprehensively summarize various load information at different levels, different load levels can be pre-divided in this application, and after determining the currently running load information, the target load level to which the load information belongs can be determined.

[0074] In one embodiment, the air conditioning device may pre-store a classification rule for dividing load levels, as well as multiple load levels divided according to the classification rule. Based on this, the air conditioning device can match the load information with the classification rule to obtain the target load level to which the load information belongs.

[0075] As an optional implementation method, through Figure 2 As shown in the process diagram, the load information mentioned above can be the load factor calculated from the module operating parameters of multiple functional modules. Based on this, the above classification rule can be multiple load factor ranges and the load level corresponding to each load factor range. For example, when the load factor is less than 0.3, the corresponding load level is low power; when the load factor is greater than or equal to 0.3 and less than 0.6, the corresponding load level is medium power; when the load factor is greater than or equal to 0.6 and less than 0.9, the corresponding load level is high power; and when the load factor is greater than or equal to 0.9, the corresponding load level is burst-enhanced power. The larger the load factor, the higher the corresponding load level.

[0076] Based on this, the air conditioning equipment can determine the target load factor range to which the current load factor belongs, and determine the load level corresponding to the target load factor range as the target load level to which the load information belongs.

[0077] In one embodiment, the load level can be divided into multiple load levels (e.g., low power level, medium power level, high power level, and burst power level) according to the load of the air conditioning equipment from low to high. The higher the load level, the higher the corresponding load. The transmit power and receive sensitivity are both positively correlated with the load level.

[0078] Based on this, when determining the target load level from multiple load levels, the air conditioning equipment, after determining the target load level according to the classification rules, and as an optional implementation method to ensure the channel quality of the wireless communication module, if the target load level is determined to be the lowest load level, then further determines the received signal strength indicator (RSSI) of the wireless communication module at this time. This RSSI measures the received signal power intensity in wireless communication, typically expressed in dBm (decibels per milliwatt).

[0079] Then, it can be determined whether the received signal strength indication is less than a preset signal threshold. The aforementioned signal threshold is a preset signal value that characterizes a low signal power intensity, for example, -100dBm.

[0080] Optionally, if the value corresponding to the received signal strength indication is less than the aforementioned signal threshold, in order to increase the communication efficiency of the wireless communication module, the target load level to which the load information belongs can be updated from the lowest load level to the previous load level adjacent to the lowest load level. For example, when the power level includes low power level, medium power level, high power level, and burst boost power level, its lowest load level can be low power level, and the previous load level adjacent to the low power level can be medium power level.

[0081] As an alternative implementation, if the target load level is determined to be the highest load level, indicating that the air conditioning equipment is under high load, the air conditioning equipment can activate the data retransmission mechanism of the wireless communication module to ensure uninterrupted communication under extreme conditions. This mechanism allows for retransmission of the data to be transmitted according to the retransmission parameters in case of data transmission failure via the wireless communication module. These retransmission parameters may include, but are not limited to, retransmission interval duration and retransmission frequency.

[0082] Step 302: Determine the communication parameters corresponding to the pre-set target load level as the target communication parameters of the wireless communication module; the above communication parameters include transmit power and / or receive sensitivity.

[0083] The aforementioned transmission power refers to the frequency parameter of the signals transmitted by the wireless communication module (such as the 4G communication module) of the air conditioning equipment when realizing IoT functions such as remote monitoring and fault diagnosis. It will be dynamically adapted according to the load level corresponding to the comprehensive load coefficient calculated from the operating frequency of the compressor and the fan, thereby balancing communication stability and energy consumption.

[0084] The aforementioned receiving sensitivity refers to the minimum signal strength (e.g., -105dBm under low load) at which the wireless communication module (e.g., 4G communication module) of the air conditioning equipment can normally receive data signals. It will dynamically adapt to the power mode corresponding to the load level and work in conjunction with the transmission power to ensure the stability of the communication link under different operating conditions.

[0085] In this step, to quickly determine the target communication parameters corresponding to the wireless communication module, the air conditioning equipment can pre-store the communication parameters corresponding to each load level. These communication parameters may include, but are not limited to, the transmit power and receive sensitivity of the wireless communication module. For example, the communication parameters corresponding to the low power level may include: transmit power of 10dBm and receive sensitivity of -105dBm; the communication parameters corresponding to the medium power level may include: transmit power of 15dBm and receive sensitivity of -100dBm; the communication parameters corresponding to the high power level may include: transmit power of 20dBm and receive sensitivity of -95dBm; and the communication parameters corresponding to the burst boost power level may include: transmit power of 25dBm and receive sensitivity of -85dBm. The receive sensitivity value can be positively correlated with the load level, but the receive sensitivity value is negatively correlated with the receive sensitivity performance.

[0086] Based on this, after determining the target load level of the currently operating load information, the air conditioning equipment can set the pre-defined communication parameters corresponding to that target load level as the target communication parameters of the wireless communication module. These communication parameters can be transmit power, receive sensitivity, or both.

[0087] Furthermore, in one embodiment, before or after determining the target load level, in order to adapt to the operating status of the air conditioning equipment in real time, the air conditioning equipment can obtain historical load information and historical communication parameters within a preset historical time period. Then, multiple current load levels can be updated based on the aforementioned historical load information and historical communication parameters. Updating the load levels may include updating the load boundary thresholds corresponding to the load levels; for example, when the load information is a load coefficient, the load coefficient threshold corresponding to each load level can be updated. The preset historical time period can be a pre-set historical operating period of the air conditioning equipment, such as the first 7 days of operation after the air conditioning equipment is installed.

[0088] For example, suppose the load level classification rules are as follows: when the load factor is less than 0.3, the corresponding load level is low power; when the load factor is greater than or equal to 0.3 and less than 0.6, the corresponding load level is medium power; when the load factor is greater than or equal to 0.6 and less than 0.9, the corresponding load level is high power; and when the load factor is greater than or equal to 0.9, the corresponding load level is burst power increase. The higher the load factor, the higher the corresponding load level. The air conditioning equipment can update the load factor thresholds of 0.3, 0.6, and 0.9 based on the above historical load information and historical communication parameters.

[0089] The technical solution provided in this application determines the target load level to which the load information belongs from a plurality of preset load levels, and determines the communication parameters corresponding to the preset target load level as the target communication parameters of the wireless communication module; the above communication parameters include transmit power and / or receive sensitivity. This technical solution deeply binds communication parameters to the actual load status of the air conditioner. Low load levels correspond to low transmission power, which can significantly reduce ineffective energy consumption, while high load levels correspond to high transmission power, which can ensure data transmission stability. This fundamentally solves the core pain point of "high power consumption under low load and unstable communication under high load". At the same time, the coordinated adaptation of transmission power and receiving sensitivity avoids communication link interruption that may be caused by adjusting the transmission power alone, thus ensuring communication reliability while saving energy. Furthermore, the design of preset multi-level correspondences makes it possible to quickly determine the target parameters by matching the load level without complex real-time calculations. The response speed is fast (adapting to the system's sampling period of 5-10 seconds) and covers all scenarios such as standby, normal operation, high-frequency operation, and extreme conditions, with strong adaptability. Finally, the solution is easy to implement. Standardized and precise communication control can be achieved by preset parameters without the need for additional complex hardware, which balances practicality and economy. It also lays the foundation for the subsequent combination of RSSI redundancy check to form a two-factor decision mechanism, further improving the robustness of communication control.

[0090] To facilitate understanding of the communication control method of the device provided in this application, the following examples are given: See Figure 4 This is a structural schematic diagram of an air conditioning device provided in an embodiment of this application. Figure 4 As shown, the structure may include: an air conditioning main control unit, a compressor drive module, a fan drive module, a 4G communication module, and an adaptive communication control unit.

[0091] Based on this system architecture, this application also provides, for example... Figure 5 A communication control method for a device is shown. See also Figure 5 This is a flowchart illustrating another embodiment of the communication control method for a device provided in this application. Figure 5 As shown, the process may include the following: The air conditioning main control unit collects the current operating frequency of the compressor (unit: Hz) and the current operating frequency of the indoor / outdoor fans (unit: Hz), and calculates the comprehensive load factor L through an internal preset algorithm. The specific formula is shown in Equation (I): Formula (1) Among them, the above For the load factor, the above For the compressor weight value, the above Given the current compressor operating frequency, the above The above refers to the compressor's maximum operating frequency (e.g., 120Hz). For the weight value of the wind turbine, the above Given the current operating frequency of the wind turbines, the above This is the current maximum operating frequency of the wind turbine (e.g., 80Hz).

[0092] Furthermore, the above It can be 0.7. It can be 0.3, thus reflecting the dominant role of the compressor in the system load.

[0093] The adaptive communication control unit divides the operating state into four intervals based on the value of L, and sets the corresponding transmit power level of the 4G module: When L<0.3: Enter low power mode, the 4G module transmit power is set to 10dBm, and the receive sensitivity is adjusted to -105dBm, which is suitable for low-frequency operation at night or standby mode; When 0.3≤L<0.6: Enter medium power mode, set the transmit power to 15dBm, adjust the receive sensitivity to -100dBm, and maintain normal data upload (such as temperature, mode). When 0.6≤L<0.9: Enter high power mode, set the transmit power to 20dBm, and adjust the receive sensitivity to -95dBm to ensure real-time control command response during high-frequency operation; When L≥0.9: Enter burst enhancement mode, increase the transmit power to 23dBm, adjust the receive sensitivity to -85dBm, and start the data retransmission mechanism to ensure uninterrupted communication under extreme conditions.

[0094] To prevent misjudgment due to poor signal environment, the system also reads the RSSI value of the 4G module. If RSSI < -100dBm and the current mode is low power, the power level is automatically increased by one level, forming a two-factor decision mechanism of "operating status + channel quality".

[0095] In terms of hardware connectivity, the air conditioning main control unit transmits FC and FF signals in real time to the adaptive communication control unit via the CAN interface. The latter then sends AT commands to the 4G module via the UART interface to dynamically set its transmission power level. The system samples operating parameters and updates power settings every 5-10 seconds to ensure timely response.

[0096] In addition, the system has a learning mode: after the initial installation, it runs continuously for 7 days, records load and communication quality data at different time periods, and automatically optimizes the weight coefficients w1, w2 and power switching thresholds to achieve personalized energy-saving optimization.

[0097] The technical solution provided in this application proposes a 4G module power regulation mechanism based on the fusion of two parameters: air conditioner compressor frequency and fan frequency. By establishing an operating state-communication power mapping model, dynamic power control of the communication module is achieved. A weighted comprehensive load coefficient is introduced into the control logic, weighting the compressor frequency (high weight) and fan frequency (medium weight) as the basis for power regulation, avoiding misjudgment based on a single parameter. Simultaneously, multiple power levels (such as low, medium, high, and burst) are set and different operating ranges are configured. Redundancy verification is performed using signal strength index (RSSI) to ensure stable communication links even at low power levels. Furthermore, an adaptive communication control unit is added between the air conditioner main control board and the 4G module to achieve closed-loop control of operating data acquisition, load calculation, and power command issuance.
