[0040] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0042] Reference Figure 1 , Figure 1 This is a schematic diagram of the control device structure of the air handling equipment in the hardware operating environment involved in the embodiments of the present invention.

[0043] Air handling units can be air conditioners, fresh air systems, or air purifiers, etc. The control device for air handling units can be a central controller within the air handling unit.

[0044] like Figure 1 As shown, the control device of the air handling equipment may include: a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. The communication bus 1002 is used to enable communication between these components. The user interface 1003 may include a display screen, and optionally, the user interface 1003 may also include a standard wired interface or a wireless interface. In this invention, the wired interface of the user interface 1003 may be a USB interface. The network interface 1004 may optionally include a standard wired interface or a wireless interface (such as a Wireless-Fidelity (Wi-Fi) interface). The memory 1005 may be a high-speed random access memory (RAM) or a non-volatile memory (NVM), such as a disk storage device. The memory 1005 may also optionally be a storage device independent of the aforementioned processor 1001.

[0045] Those skilled in the art will understand that Figure 1 The structure shown does not constitute a limitation on the control equipment of the air handling equipment, and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0046] like Figure 1 As shown, the memory 1005, which is identified as a computer storage medium, may include an operating system, a network communication module, a user interface module, and a control program.

[0047] exist Figure 1In the control device of the air handling equipment shown, the network interface 1004 is mainly used to connect to the backend server and communicate data with the backend server; the user interface 1003 is mainly used to connect to the user equipment; the control device of the air handling equipment calls the control program stored in the memory 1005 through the processor 1001 and executes the control method of the air handling equipment provided in the embodiment of the present invention.

[0048] Based on the above hardware structure, an embodiment of the control method for the air handling equipment of the present invention is proposed.

[0049] Reference Figure 2 , Figure 2 This is a flowchart illustrating the first embodiment of the control method for the air handling equipment of the present invention, which presents the first embodiment of the control method for the air handling equipment of the present invention.

[0050] In the first embodiment, the control method for the air handling equipment includes the following steps:

[0051] Step S10: Obtain the current purification level of the air handling unit in the corresponding working area.

[0052] It should be understood that the execution entity in this embodiment is the control device of the aforementioned air handling equipment, which has functions such as data processing, data communication, and program execution. The air handling equipment can be an air conditioner, a fresh air unit, or an air purifier, etc., and the control device can be the central controller within the air handling equipment. Of course, it can also be other devices with similar functions, and this embodiment does not limit it.

[0053] The working area of ​​an air handling unit refers to the area it covers during operation. For example, if the air handling unit is installed in a bedroom, its working area is the bedroom; if it is installed in a living room, its working area is the living room. Of course, if the living room and bedroom are connected, its working area can be both the living room and the bedroom.

[0054] It should be noted that air handling units have purification functions. The purification function uses a fan to draw air into the machine, which is then filtered through internal filters to remove dust, odors, and disinfect. These filters consist of different functional filters such as HEPA, activated carbon, and electrostatic filters. HEPA filters remove particulate matter, while activated carbon filters absorb odors. Alternatively, they can directly release purifying and sterilizing agents into the air, which then disperse throughout the room for comprehensive purification. The current purification volume can be defined as the amount of gas concentration adjustment in the working area after the air handling unit performs its purification function. For example, if the air handling unit is used to reduce the PM2.5 concentration in the working area, the current purification volume can be defined as the amount of PM2.5 concentration reduction after the unit performs its PM2.5 reduction function. Or, if the air handling unit is used to increase the oxygen concentration in the working area, the current purification volume can be defined as the amount of oxygen concentration increase after the unit performs its oxygen increase function.

[0055] In practice, the current purification level can be input by the user, and the control device of the air handling unit will obtain the current purification level after receiving the user input. Alternatively, the current purification level can also be determined based on the operating parameters of the air handling unit itself; that is, the control device of the air handling unit can predict the current purification level based on the operating parameters of the air handling unit after it has executed the air conditioning function.

[0056] Step S20: Obtain the initial air quality parameters of the work area.

[0057] It should be noted that the initial air quality parameter can be the gas concentration in the working area when the air handling unit starts its air conditioning function. For example, if the air handling unit is used to reduce the PM2.5 concentration in the working area, the initial air quality parameter can be the PM2.5 concentration in the working area when the air handling unit starts performing the PM2.5 reduction function. Or, if the air handling unit is used to increase the oxygen concentration in the working area, the initial air quality parameter can be the oxygen concentration in the working area when the air handling unit starts performing the oxygen increase function.

[0058] In this embodiment, to reduce the air handling equipment's dependence on sensors, step S20 may include: acquiring the air quality parameters of the external environment and using the air quality parameters as initial air quality parameters; or, upon receiving an operating command, using the air quality parameters detected by other devices as initial air quality parameters.

[0059] Understandably, users typically connect their work area to the external environment before using air handling equipment. However, after activating the air handling equipment, users often choose to isolate the work area from the external environment. Therefore, when the air handling equipment is turned on, the air quality parameters in the work area are essentially the same as those in the external environment, and the external air quality parameters can be used as the initial air quality parameters. Specifically, the control unit of the air handling equipment connects to a meteorological database via the internet, thereby directly obtaining the external air quality parameters from the meteorological database.

[0060] Alternatively, in an IoT environment, the control unit of the air handling unit can connect to other devices to acquire their detection data. When the air handling unit starts operating, the air quality parameters detected by these other devices are used as the initial air quality parameters. The operating command is used to control the air handling unit to begin its air conditioning function; it can be input directly by the user or initiated by the user via a mobile terminal.

[0061] Step S30: Determine the current air quality parameters based on the current purification capacity and the initial air quality parameters.

[0062] Understandably, air handling units need to adjust their operating parameters in real time based on the current air quality parameters when performing air conditioning functions. This implementation reduces the air handling unit's reliance on sensors; the current air quality parameters are calculated based on the current purification level and the initial air quality parameters, without requiring sensors to detect the current air quality parameters in real time.

[0063] For example, if an air handling unit is used to reduce the PM2.5 concentration in a working area, the initial air quality parameter can be a PM2.5 concentration of 90, and the current purification level can be a PM2.5 concentration of 40, then the current air quality parameter can be a PM2.5 concentration of 50; or the current purification level can be 50%, then the current air quality parameter can be a PM2.5 concentration of 45.

[0064] Step S40: Control the air handling equipment to perform the purification function according to the current air quality parameters.

[0065] Understandably, the operating parameters of air handling equipment can be adjusted based on current air quality parameters. For example, when the PM2.5 concentration is 60, the air handling equipment can operate at a high setting, while when the PM2.5 concentration is 30, it can operate at a low setting. Controlling the air handling equipment to perform its purification function can include adjusting the setting to a high level, lowering the setting, or turning off the purification function.

[0066] In practical implementation, a correspondence can be established between air quality parameters and the operating parameters of air handling equipment. Then, the operating parameters of the air handling equipment corresponding to the air quality parameters can be determined based on this correspondence. This correspondence can be obtained through experimental analysis under specific air quality conditions, testing and verifying the appropriate operating parameters for the air handling equipment, and then storing the correspondence. Alternatively, this correspondence can be derived by fitting historical operating data.

[0067] In this embodiment, the current purification level of the air handling equipment in the corresponding working area is obtained; the initial air quality parameters of the working area are also obtained; then the current air quality parameters are determined based on the current purification level and the initial air quality parameters; and then the operation of the air handling equipment is controlled based on the current air quality parameters. Thus, without relying on sensors to detect the environment in the working area in real time, the current air quality parameters of the environment in the working area are predicted, and the air handling equipment is controlled based on the prediction results, thereby improving the reliability of the air handling equipment.

[0068] Reference Figure 3 , Figure 3 This is a flowchart illustrating a second embodiment of the control method for the air handling equipment of the present invention. Based on the first embodiment described above, a second embodiment of the control method for the air handling equipment of the present invention is proposed.

[0069] In the second embodiment, step S10 may include:

[0070] Step S101: Obtain the operating parameters of the air handling equipment.

[0071] In this embodiment, in order to more accurately determine the amount of gas concentration adjustment in the working area after the air handling unit performs the purification function, prediction is made using the operating parameters of the air handling unit.

[0072] Specifically, the control unit of the air handling unit stores the operating parameters during the air handling unit's purification function. Then, when calculating the current purification capacity, it reads the memory to obtain the operating parameters. These operating parameters may include at least one of the following: operating time, operating power, or operating speed.

[0073] Step S102: Determine the current purification capacity of the air handling unit in the corresponding working area based on the operating parameters.

[0074] Generally, when air handling equipment maintains stable operating parameters to regulate the air, the gases in the air can change at a relatively stable rate. Therefore, there is a certain correlation between the operating parameters of the air handling equipment and the current purification capacity. Specifically, the current purification capacity corresponding to the operating parameters can be determined based on a first mapping relationship, which includes the correspondence between operating parameters and purification capacity.

[0075] Alternatively, the area of ​​the working area can be obtained, and the current purification level corresponding to the area and operating parameters can be determined based on a second mapping relationship. This second mapping relationship includes the correspondence between the working area, operating parameters, and purification level. To more accurately determine the impact of the air handling unit's operating parameters on the current purification level, the area of ​​the working area can also be considered. With operating parameters remaining constant, a larger area results in a lower purification level. The area of ​​the working area can be identified through a camera / radar, or it can be input by the user.

[0076] The first and second mapping relationships reflect the changes in operating parameters and gas content within the working area. (Refer to...) Figure 4 , Figure 4 This is a first schematic diagram illustrating the mapping relationship between the operating parameters and purification capacity of the air handling equipment in this invention. For example... Figure 4 As shown, taking the air handling unit's purification function to reduce the PM2.5 concentration in the working area as an example, as the air handling unit's purification operation time increases, the PM2.5 gradually decreases and eventually stabilizes.

[0077] Alternatively, the first and second mapping relationships can also reflect the ratio of changes in operating parameters to changes in gas content within the working area. (Refer to...) Figure 5 , Figure 5 This is a first schematic diagram illustrating the mapping relationship between the operating parameters and purification capacity of the air handling equipment in this invention. For example... Figure 4 As shown, taking the air handling unit's purification function to reduce the PM2.5 concentration in the working area as an example, as the air handling unit's purification operation time increases, the PM2.5 concentration ratio between the inside and outside gradually decreases and eventually stabilizes. The PM2.5 concentration ratio refers to the ratio of the PM2.5 concentration in the working area to the PM2.5 concentration in the external environment.

[0078] In practical implementation, a first mapping relationship and a second mapping relationship can be pre-set and stored. The first mapping relationship or the second mapping relationship is obtained by analyzing the working condition experiments, testing the change in carbon dioxide concentration increment in the working area under different operating times, different operating power or different operating levels, and different working area areas, and then fitting the results to obtain the first mapping relationship or the second mapping relationship.

[0079] Alternatively, a first mapping relationship and a second mapping relationship can be calculated and generated based on historical environmental data during the operation of the air handling equipment. Historical environmental data can include air quality parameters corresponding to different operating times, operating power levels, or operating speeds of the air handling equipment when performing air conditioning functions. These parameters are then fitted to obtain the first and second mapping relationships. To ensure data accuracy, the air handling equipment can utilize sensors on other devices to detect the aforementioned air quality parameters.

[0080] In this embodiment, by acquiring the operating parameters of the air handling equipment, and then determining the current purification capacity of the air handling equipment in the corresponding working area based on the operating parameters, the current purification capacity is determined more accurately, ensuring that the air handling equipment effectively regulates the air operation in the working area.

[0081] Reference Figure 6 , Figure 6 This is a flowchart illustrating a third embodiment of the control method for the air handling equipment of the present invention. Based on the first and second embodiments described above, a third embodiment of the control method for the air handling equipment of the present invention is proposed.

[0082] In the third embodiment, the method further includes the following steps before step S10:

[0083] Step S01: Check if the air quality sensor on the air handling equipment is abnormal.

[0084] Step S02: When the air quality sensor malfunctions, perform the step of obtaining the current purification level of the air handling unit in the corresponding working area.

[0085] It should be noted that the control method for the air handling equipment provided in this embodiment can also be applied to air handling equipment equipped with an air quality sensor. When the air quality sensor malfunctions, the control device of the air handling equipment switches its control program to execute the control method provided in this embodiment, ensuring the normal operation of the air handling equipment.

[0086] In practical implementation, the control equipment of the air handling unit can determine whether the air quality sensor is malfunctioning by detecting its output. If the air quality sensor does not output data, or if its output data remains unchanged for an extended period, it is determined that the air quality sensor is malfunctioning. Of course, other detection methods can also be used; the type of air quality sensor can be a carbon dioxide sensor or an oxygen sensor, etc., and this implementation does not limit this approach.

[0087] In addition, since the air handling unit is equipped with an air quality sensor, when the air quality sensor is functioning normally, the air handling unit stores the detection data from the air quality sensor, and then analyzes it in conjunction with the air handling unit's own operating parameters to obtain the mapping relationship between the operating parameters and the current purification capacity.

[0088] In addition, to improve user experience, environmental parameters within the work area can be obtained; combined with environmental parameters and carbon dioxide concentration, the operating parameters of the air handling equipment can be determined, and the operation of the air handling equipment can be controlled.

[0089] It should be noted that environmental parameters can include light intensity, noise level, etc. Air handling units inevitably generate noise when purifying the air. Environmental parameters can reflect the user's tolerance level for noise. Generally, users have a higher tolerance for noise during the day and a lower tolerance at night. Alternatively, when noise levels are high, the operation of the air handling unit has a lower impact on the overall environmental noise level and a lower impact on the user; conversely, when noise levels are low, the operation of the air handling unit has a higher impact on the overall environmental noise level and a higher impact on the user. Therefore, the operating parameters determined based on carbon dioxide concentration can be adjusted according to the user's noise tolerance level. For example, if the operating level determined by carbon dioxide concentration is level 4, then when the user's noise tolerance is low, the operating level should be reduced to level 3; when the user's noise tolerance is within acceptable limits, the operating level should be maintained at level 4.

[0090] In this embodiment, the control method for the air handling equipment can also be applied to air handling equipment equipped with an air quality sensor. By detecting whether the air quality sensor on the air handling equipment is malfunctioning, and executing the step of obtaining the current purification level of the air handling equipment in the corresponding working area when the air quality sensor is malfunctioning, it can be ensured that the air handling equipment can normally adjust the air condition of the working area after the air quality sensor malfunctions, thereby improving the user experience.

[0091] Furthermore, embodiments of the present invention also propose a storage medium storing a control program for an air handling device. When executed by a processor, the control program implements the steps of the control method for the air handling device as described above. Since this storage medium can employ the technical solutions of all the above embodiments, it at least possesses the beneficial effects brought about by the technical solutions of the above embodiments, and will not be elaborated further here.

[0092] In addition, refer to Figure 7 , Figure 7 This is a structural block diagram of a first embodiment of the control device for an air handling equipment according to the present invention. The present invention also proposes a control device for an air handling equipment.

[0093] In this embodiment, the control device for the air handling equipment includes:

[0094] The first detection module 10 is used to obtain the current purification level of the air handling equipment in the corresponding working area.

[0095] The working area of ​​an air handling unit refers to the area it covers during operation. For example, if the air handling unit is installed in a bedroom, its working area is the bedroom; if it is installed in a living room, its working area is the living room. Of course, if the living room and bedroom are connected, its working area can be both the living room and the bedroom.

[0096] It should be noted that air handling units have purification functions. The purification function uses a fan to draw air into the machine, which is then filtered through internal filters to remove dust, odors, and disinfect. These filters consist of different functional filters such as HEPA, activated carbon, and electrostatic filters. HEPA filters remove particulate matter, while activated carbon filters absorb odors. Alternatively, they can directly release purifying and sterilizing agents into the air, which then disperse throughout the room for comprehensive purification. The current purification volume can be defined as the amount of gas concentration adjustment in the working area after the air handling unit performs its purification function. For example, if the air handling unit is used to reduce the PM2.5 concentration in the working area, the current purification volume can be defined as the amount of PM2.5 concentration reduction after the unit performs its PM2.5 reduction function. Or, if the air handling unit is used to increase the oxygen concentration in the working area, the current purification volume can be defined as the amount of oxygen concentration increase after the unit performs its oxygen increase function.

[0097] In practice, the current purification level can be input by the user, and the control device of the air handling unit will obtain the current purification level after receiving the user input. Alternatively, the current purification level can also be determined based on the operating parameters of the air handling unit itself, that is, the first detection module 10 predicts the current purification level based on the operating parameters of the air handling unit after it executes the air conditioning function.

[0098] The second detection module 20 is used to acquire the initial air quality parameters of the working area.

[0099] It should be noted that the initial air quality parameter can be the gas concentration in the working area when the air handling unit starts its air conditioning function. For example, if the air handling unit is used to reduce the PM2.5 concentration in the working area, the initial air quality parameter can be the PM2.5 concentration in the working area when the air handling unit starts performing the PM2.5 reduction function. Or, if the air handling unit is used to increase the oxygen concentration in the working area, the initial air quality parameter can be the oxygen concentration in the working area when the air handling unit starts performing the oxygen increase function.

[0100] In this embodiment, to reduce the air handling equipment's dependence on sensors, step S20 may include: acquiring the air quality parameters of the external environment and using the air quality parameters as initial air quality parameters; or, upon receiving an operating command, using the air quality parameters detected by other devices as initial air quality parameters.

[0101] Understandably, users typically have their work area connected to the external environment before using the air handling unit. However, after activating the air handling unit, users often choose to isolate the work area from the external environment. Therefore, when the air handling unit is turned on, the air quality parameters in the work area are essentially the same as those in the external environment, and the external air quality parameters can be used as the initial air quality parameters. Specifically, the second detection module 20 connects to a meteorological database via the internet, thereby directly obtaining the external air quality parameters from the meteorological database.

[0102] Alternatively, in an IoT environment, the second detection module 20 can connect to other devices to acquire their detection data. When the air handling unit starts operating, the acquired air quality parameters detected by these other devices will be used as the initial air quality parameters. The operating command is used to control the air handling unit to begin its air conditioning function; it can be input directly by the user or initiated by the user via a mobile terminal.

[0103] The calculation module 30 is used to determine the current air quality parameters based on the current purification volume and the initial air quality parameters.

[0104] Understandably, air handling units need to adjust their operating parameters in real time based on the current air quality parameters when performing air conditioning functions. This implementation reduces the air handling unit's reliance on sensors; the current air quality parameters are calculated based on the current purification level and the initial air quality parameters, without requiring sensors to detect the current air quality parameters in real time.

[0105] For example, if an air handling unit is used to reduce the PM2.5 concentration in a working area, the initial air quality parameter can be a PM2.5 concentration of 90, and the current purification level can be a PM2.5 concentration of 40, then the current air quality parameter can be a PM2.5 concentration of 50; or the current purification level can be 50%, then the current air quality parameter can be a PM2.5 concentration of 45.

[0106] The control module 40 is used to control the air handling equipment to perform the purification function according to the current air quality parameters.

[0107] Understandably, the operating parameters of air handling equipment can be adjusted based on current air quality parameters. For example, when the PM2.5 concentration is 60, the air handling equipment can operate at a high setting, and when the PM2.5 concentration is 60, it can operate at a low setting. Controlling the air handling equipment to perform its purification function can include increasing the setting, decreasing the setting, or turning off the purification function.

[0108] In practical implementation, a correspondence can be established between air quality parameters and the operating parameters of air handling equipment. The second detection module 20 determines the operating parameters of the air handling equipment corresponding to the air quality parameters based on this correspondence. This correspondence can be obtained and stored by analyzing operating conditions, testing reasonable operating parameters of the air handling equipment under the specified air quality parameters, and then performing the corresponding analysis. Alternatively, this correspondence can be derived by fitting historical operating data.

[0109] In this embodiment, the first detection module 10 acquires the current purification level of the air handling equipment in the corresponding working area and the initial air quality parameters of the working area; the calculation module 30 determines the current air quality parameters based on the current purification level and the initial air quality parameters; the control module 40 controls the operation of the air handling equipment based on the current air quality parameters, thereby predicting the current air quality parameters of the environment in the working area without relying on sensors for real-time detection of the environment, and controlling the air handling equipment based on the prediction results, thus ensuring the reliability of the operation of the air handling equipment.

[0110] In one embodiment, the first detection module 10 is further configured to acquire the operating parameters of the air handling equipment and determine the current purification capacity of the air handling equipment in the corresponding working area based on the operating parameters.

[0111] In one embodiment, the calculation module 30 is further configured to determine the current purification amount corresponding to the operating parameters according to a first mapping relationship, the first mapping relationship including the correspondence between the operating parameters and the purification amount; or, to obtain the area of ​​the working area and determine the current purification amount corresponding to the area and the operating parameters according to a second mapping relationship, the second mapping relationship including the area of ​​the working area and the correspondence between the operating parameters and the purification amount.
