Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to an air conditioning system. Background Art

[0002] Traditional wall-mounted air conditioners or floor-standing air conditioners are usually installed in a fixed position in the room, with limited air supply coverage angle. To solve this problem, users may use another electric fan as an auxiliary air supply device, manually adjusting the fan position and air supply angle according to usage needs to achieve a uniform temperature in the space.

[0003] In order to simplify user operations, the prior art discloses a method for executing path setting of air equipment of a smart terminal, such as the technical solution disclosed in the Chinese patent application (CN105571052A): "It includes the following steps: setting the relative position and wind setting direction of at least one air equipment i on the smart terminal; using an electronic pointing device (electronic compass, geomagnetic sensor and direction sensor, etc.) to obtain a first deflection angle of a reference line of the smart terminal (a reference line selected on the smart terminal, used to set the wind setting direction of the air equipment on the smart terminal and the relative direction of the smart terminal) relative to the reference direction, and calculating a second deflection angle of the wind setting direction relative to the smart terminal; calculating a third deflection angle of the wind setting direction relative to the reference direction according to the first deflection angle and the second deflection angle; generating a set of wind direction setting instructions according to the third deflection angle of each wind setting direction." ...

The smart terminal is one of a smart phone, a PAD, a wearable device with a screen and a handheld computer; the air equipment includes at least one of an air conditioner, an electric fan and an air purifier."

[0004] The above method disclosed in the prior art can plan and execute the air supply path of the air equipment, but the operation is relatively complicated. For the elderly or people who are not familiar with the operation of smart terminals, learning "manually or automatically setting the relative position of at least one air equipment on the smart terminal screen, and sliding operations or setting the wind setting direction of the air equipment by clicking on the two end points of the wind direction" has a high learning cost, and the proportion of setting errors is high, which may seriously affect the user's actual experience; in addition, it is necessary to set an electronic compass, geomagnetic sensor, direction sensor, etc. in the smart terminal, which has high requirements on the hardware of the device.

[0038] In order to make the purpose and implementation method of the present application clearer, the exemplary implementation method of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0039] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0040] The terms "first", "second", "third", etc. in the specification and claims of this application and the above drawings are used to distinguish similar or similar objects or entities, and do not necessarily mean to limit a specific order or sequence, unless otherwise noted. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances.

[0041] The terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to all the components expressly listed but may include other components not expressly listed or inherent to such product or device. Example

[0042] Figure 1 It is an explanatory diagram showing an example of the air conditioning system 1 according to the present embodiment. Figure 1 The illustrated air conditioning system includes an air conditioning device 10 , an air blowing device 30 , and a learning control device 20 .

[0043] The air conditioner 10 is a device that satisfies the indoor cooling and heating load requirements in a timely manner by controlling the refrigerant circulation amount of the compressor and the refrigerant flow rate entering the indoor heat exchanger in the refrigeration system. Specifically, the air conditioner 10 adopts a compression refrigeration cycle, and has four major components, namely, a compressor, a condenser (high-temperature heat source), a throttling element, and an evaporator (low-temperature heat source), to form a refrigerant circuit. In the refrigerant circuit, the refrigerant circulates in sequence through the compressor, the condenser, the throttling element, and the evaporator.

[0044] In this embodiment, the cooling and heating cycle of the air conditioning device 10 includes a series of processes involving compression, condensation, expansion and evaporation to cool or heat the indoor space.

[0045] The low-temperature and low-pressure refrigerant enters the compressor, which compresses it into high-temperature and high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0046] The throttling element, such as the expansion valve, expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioning device 10 can adjust the temperature of the indoor space of the air-conditioned room.

[0047] The outdoor unit of the air-conditioning device 10 refers to the part of the refrigeration cycle including the compressor, the outdoor heat exchanger and the outdoor fan, the indoor unit of the air-conditioning device 10 refers to the part including the indoor heat exchanger and the indoor fan, and a throttling device (such as a capillary tube or an electronic expansion valve) can be provided in the indoor unit or the outdoor unit.

[0048] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioning device 10 performs a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioning device 10 performs a cooling mode.

[0049] The indoor heat exchanger and the outdoor heat exchanger are switched to serve as a condenser or an evaporator, generally using a four-way valve. For details, please refer to the configuration of the conventional air conditioning device 10, which will not be described in detail here.

[0050] The refrigeration working principle of the air-conditioning device 10 is: the operation of the compressor makes the indoor heat exchanger (in the indoor unit, it is the evaporator at this time) in an ultra-low pressure state, the liquid refrigerant in the indoor heat exchanger evaporates rapidly to absorb heat, and the wind flow blown by the indoor fan is cooled by the indoor heat exchanger coil and becomes cold air blown into the room. The evaporated refrigerant is pressurized by the compressor and condensed into liquid under the high-pressure environment of the outdoor heat exchanger (in the outdoor unit, it is the condenser at this time), releasing heat, and dissipating the heat into the atmosphere through the outdoor fan. Such a cycle achieves the refrigeration effect.

[0051] The heating working principle of the air conditioning device 10 is as follows: the gaseous refrigerant is pressurized by the compressor to become a high-temperature and high-pressure gas, enters the indoor heat exchanger (the condenser at this time), condenses and liquefies to release heat, becomes a liquid, and heats the indoor air at the same time, thereby achieving the purpose of increasing the indoor temperature. The liquid refrigerant is decompressed by the throttling device and enters the outdoor heat exchanger (the evaporator at this time), evaporates and gasifies to absorb heat, becomes a gas, and absorbs heat from the outdoor air (the outdoor air becomes colder), becomes a gaseous refrigerant, and enters the compressor again to start the next cycle.

[0052] The air conditioning device 10 uses a variable frequency compressor to achieve compressor capacity control, and supplies AC power to the compressor through the variable frequency device. When the output frequency of the variable frequency device changes, the speed of the compressor changes, achieving air conditioning capacity matching different heat loads.

[0053] In some optional embodiments of the present application, the indoor unit may adopt an independent air supply mechanism. For example, a wall-mounted air supply structure is adopted, that is, a return air outlet is arranged above the shell and an air supply outlet is arranged below the shell; a floor-standing air supply structure is adopted, that is, an air supply outlet is arranged above the shell and return air outlets are arranged on the left and right sides below the shell; in addition, it can also be a duct-type air supply structure, or an air supply structure embedded in the ceiling, etc.

[0054] The air conditioning device 10 is provided with an air conditioning control unit 100, which is used to control the operation of the air conditioning device 10 according to the operation instructions of the air conditioning control terminal 101. The air conditioning control unit 100 may be a dedicated processor, a central processing unit (CPU), etc. In some embodiments of the present application, the air conditioning control unit 100 is arranged on the outdoor unit mainboard. The outdoor unit mainboard is also provided with components such as a storage unit, an input / output interface, and a communication interface. The storage unit may include a volatile memory and / or a non-volatile memory. The storage unit is configured to store instructions or data associated with at least one component of the outdoor unit, such as storing an application. The input / output interface may be a serial communication interface. The communication interface may be a software interface that supports different wireless communication protocols. A filter circuit and a switching power supply circuit are usually also integrated on the outdoor unit mainboard.

[0055] The air conditioning control unit 100 can execute the application program stored in the storage unit to compare the parameters related to the indoor ambient temperature in the air-conditioned room collected at any time with the set temperature stored in the storage unit, and output a control signal after calculation processing, so that the variable frequency compressor changes continuously within the set frequency range (for example, 12-150Hz); or according to the information collected by the temperature sensor set at the inlet and outlet of the electronic expansion valve, the compressor suction port, etc., the opening of the electronic expansion valve is controlled to change the flow rate of the refrigerant at any time. The speed of the compressor corresponds to the opening of the electronic expansion valve, so that the delivery amount of the compressor is adapted to the supply amount through the electronic expansion valve, so that the superheat is not too large, and the capacity of the evaporator is maximized, thereby achieving the best control of the air conditioning device 10.

[0056] In some optional real-time methods of the present application, the indoor ambient temperature and the set temperature in the above parameters are obtained by a processing chip. The processing chip is arranged on the indoor unit mainboard, and the indoor unit mainboard and the outdoor unit mainboard are connected to each other through a serial communication interface. The processing chip is configured to drive the indoor fan to work, receive and process sampling signals of various sensors, and realize the communication function with the air conditioning control terminal 101.

[0057] The air conditioning control terminal 101 is configured to input operation instructions, including set temperature, operation mode (cooling / heating) and air supply mode (high speed / medium speed / low speed / silent) and the like.

[0058] In some optional embodiments of the present application, the air conditioner control terminal 101 is an infrared remote controller. The infrared remote controller is provided with buttons for inputting operation instructions such as setting temperature and operation mode. The infrared remote controller is provided with a transmitter, and the infrared remote controller generates a remote control coded pulse corresponding to the operation instruction, and drives the infrared transmitting tube to output an infrared remote control signal. A receiver is provided on the control panel of the indoor unit of the air conditioner, and the receiver completes the amplification, detection, shaping, and demodulation of the remote control signal to obtain the remote control coded pulse, and further controls the operation of the air conditioner 10.

[0059] In some optional implementations of the present application, the air conditioning control terminal 101 is a wired controller, which is provided with an operation interface for inputting set temperature and operation mode, and a display interface for displaying the real-time temperature or operation status of the air-conditioned room.

[0060] In some optional implementations of the present application, the air conditioning control terminal 101 is a mobile smart terminal. The mobile smart terminal has an application interface, through which the set temperature and operation mode can be input and the real-time temperature or operation status of the air-conditioned room can be displayed.

[0061] The air supply device 30 is an air conditioning device that can be installed in the air-conditioned room. One or more fans are installed in the air supply device 30. The fan can be a centrifugal fan, an axial flow fan, a diagonal flow fan, etc. The air supply device 30 can increase the gas pressure and deliver the gas. From the perspective of form, the air supply device 30 can be an electric fan, an air purification device, a household dehumidifier, or an indoor fan in the indoor unit of another air-conditioning device 10. The air supply device 30 is independently installed from the air-conditioning device 10, that is, its power supply, operation, and air supply trajectory are all independent of the air-conditioning device 10.

[0062] The air supply device 30 is provided with an infrared receiver 300 for receiving infrared operations. The infrared receiver 300 is used to receive operation instructions from the infrared remote controller 301 of the air supply device to control the operation of the air supply device 30, that is, the infrared receiver 300 can amplify, detect, shape, and demodulate the remote control signal of the infrared remote controller 301 of the air supply device to obtain remote control coded pulses, and further control the operation of the air supply device 30. A microprocessor is provided in the air supply device 30 to decode the operation instructions and execute the corresponding remote control function.

[0063] The learning control device 20 includes an infrared transmitter 200. The learning control device 20 is configured to learn and store the operation instructions of the air supply device infrared remote controller 301 to the air supply device 30 when the air conditioner 10 is in operation. The learning control device 20 is also configured to select from the stored operation instructions according to the actual heat load of the air-conditioned room after storing at least one operation instruction of the air supply device infrared remote controller 301 to the air supply device 30, and output the selected matching operation instruction to the infrared receiver 300 through the infrared transmitter 200 to control the operation of the air supply device 30.

[0064] In some optional implementations of the present application, the infrared signal transmitting unit 200 in the learning control device 20 may be disposed on the housing of the indoor unit of the air conditioner. Other functions of the learning control device 20 are implemented by a processing chip.

[0065] Figure 2 is a flow chart showing the functions of the learning control device 20. In this embodiment, the air supply device 30 is an electric fan. The learning control device 20 determines whether the air conditioning device 10 is in an operating state (such as Figure 2 When the air conditioner 10 is in operation, the infrared remote controller 301 of the air supply device 30 is learned and stored (eg, Figure 2 As shown in step S12): if there is an operation instruction output by the infrared remote controller 301 of the air supply device to the air supply device 30 when the air conditioner 10 is in operation, the learning control device 20 learns and stores the operation instruction; if there is no operation instruction output by the infrared remote controller 301 of the air supply device to the air supply device 30, the learning control device 20 remains in a waiting state; the learning control device 20 determines whether at least one operation instruction of the infrared remote controller 301 of the air supply device to the air supply device 30 is stored (such as Figure 2 When the learning control device 20 stores at least one operation instruction of the air supply device infrared remote controller 301 to the air supply device 30, the learning control device 20 selects from the stored operation instructions according to the actual heat load of the air-conditioned room (such as Figure 2As shown in step S14): For example, if the learning control device 20 stores the operation instructions of the infrared remote controller 301 of the air supply device to the air supply device 30, including: power on (function instruction code 01), high wind (function instruction code 02), medium wind (function instruction code 03), low wind (function instruction code 04), swing air supply (function instruction code 05), stop swing air supply (function instruction code 06) and power off (function instruction code 00); if the operation instruction input by the air conditioning control terminal 101 corresponds to the cooling mode, the set temperature is 19°C, the high-speed air supply mode, and the temperature difference between the real-time temperature and the set temperature of the air-conditioned room deviates from the target interval, then the learning control device 20 selects from the stored operation instructions according to the degree to which the real-time heat load of the air-conditioned room deviates from the set target. The principle of selection can be that the higher the real-time heat load, the greater the air supply volume; the smaller the real-time heat load, the smaller the air supply volume. For example, power on (function instruction code 01) and high wind (function instruction code 02) are selected. The learning control device 20 outputs the selected matching operation instruction to the infrared receiving unit 300 through the infrared transmitting unit 200 to control the operation of the air supply device 30 (such as Figure 2 If the temperature difference between the real-time temperature and the set temperature remains within the target range, the learning control device 20 exemplarily selects shutdown (function instruction code 00) as a matching operation instruction, and outputs it to the infrared receiving unit 300 through the infrared transmitting unit 200 to control the operation of the air supply device 30.

[0066] The learning control device 20 can learn the operation instructions of any air supply device 30 having an infrared receiver 300. Through this configuration, the air conditioner 10 can be adapted to any air supply device 30 having an infrared receiver 300 and an infrared remote controller 301 for the air supply device, and the adaptation process does not rely on a local area network or a mobile smart terminal; the issuance of matching operation instructions is not restricted by the network environment, and there will be no time difference in the control effect. The air supply device 30 responds quickly, realizing the linkage between the air conditioner 10 and the air supply device 30, and achieving an energy-saving control effect. The learning control device 20 is configured to learn and store the operation instructions of the air supply device infrared remote control 301 to the air supply device 30 when the air conditioning device 10 is in operation, which matches the user's expectations. For example, when the air conditioning device 10 is in operation, the learning control device 20 never learns and stores the high wind instruction, which means that the user does not need to set the electric fan to high wind (high wind may cause discomfort) when turning on the air conditioning device 10 and the electric fan. In this case, no matter how the actual heat load of the air-conditioned room changes, the learning control device 20 will not set the electric fan to high wind, and will always choose between medium wind and low wind to ensure that the effect of intelligent control matches the user. During the entire learning and setting process, the user still uses the traditional infrared remote control to operate the air supply device 30, and there is no need to operate on the application of the smartphone. It is more suitable for the elderly and people who are not familiar with smart devices, and the user experience is good.

[0067] In some optional embodiments of the present application, such as Figure 3 As shown, the air supply device 30 has an air supply device storage unit 302. The air supply device storage unit 302 may be a volatile memory and / or a non-volatile memory integrated in the air supply device 30. The air supply device storage unit 302 is used to store the operation instructions of the air supply device infrared remote controller 301 to the air supply device 30. The learning control device 20 learns the user's operation instructions from the air supply device storage unit 302. Specifically, when used for the first time or initialized, the learning control device 20 may perform the following operations: Figure 4 The multiple steps shown are: determining whether the air conditioning device 10 is in a standby state (such as Figure 4 When the air conditioner 10 is in the standby state, the learning control device 20 attempts to establish a communication connection with the air supply device 30 (such as Figure 4 As shown in step S22 in the figure), for example, attempting to establish an infrared communication connection; determining whether the communication connection is successful (such as Figure 4 When the communication connection is successful, the initial operation instruction of the air supply device 30 by the infrared remote controller 301 of the air supply device 30 is read from the air supply device storage unit 302 (such as Figure 4 As shown in step S24); the learning control device 20 learns and stores the read initial operation instruction (such as Figure 4As shown in step S25, the initial operation instruction can be regarded as the user's operating habits for the air supply device 30. Taking the electric fan as an example, the user may only use high wind or medium wind, or only use low wind, or only use swing air supply. The learning control device 20 learns and stores the read initial operation instruction; the power-off protection (such as Figure 4 As shown in step S26 in the figure), even if the power of the learning control device 20 is turned off, the storage state of the initial operation instruction remains unchanged. When the air supply device 30 is used in conjunction with the air conditioning device 10 for the first time, the learning control device 20 can select from the stored initial operation instructions, and output the selected matching operation instruction to the infrared receiving unit 300 through the infrared transmitting unit 200 to control the operation of the air supply device 30; for example, if the user does not usually use high wind or medium wind instructions, during the linkage control, the learning control device 20 will automatically filter out the high wind or medium wind instructions, and only select from the stored operation instructions, so that the linkage control is more in line with the user's usage habits.

[0068] In some optional embodiments of the present application, such as Figure 5 As shown, the air supply device 30 and the air conditioner 10 can also be paired during the use of the air conditioner 10; for example, the user may realize that the adjustment effect is not ideal during the use of the air conditioner 10, and thus add an electric fan in the air-conditioned room. In this case, Figure 5 As shown, the learning control device 20 performs the following Figure 5 The multiple steps shown are: determining whether the air conditioning device 10 is in operation (such as Figure 5 When the air conditioner 10 is in operation, the learning control device 20 attempts to establish a communication connection with the air supply device 30 (such as Figure 5 As shown in step S32 in the figure), for example, attempting to establish an infrared communication connection; determining whether the communication connection is successful (such as Figure 5 When the communication connection is successful, the auxiliary operation instruction (such as the auxiliary operation instruction of the infrared remote controller 301 of the air supply device 30) of the air supply device 30 is read from the air supply device storage unit 302. Figure 5 As shown in step S34, the auxiliary operation instruction can be regarded as the user's active intervention operation when the adjustment effect of the air conditioning device 10 is not ideal; the learning control device 20 learns and stores the auxiliary operation instruction (such as Figure 5 As shown in step S35); performing power-off protection on the learned and stored auxiliary operation instructions (such as Figure 5As shown in step S36 in the figure), even if the power of the learning control device 20 is turned off, the storage state of the initial operation instruction remains unchanged; when an additional air supply device 30 is added, the user will definitely perform at least the power on and off operations, so that the learning control device 20 can also realize the pairing and learning process with the newly added air supply device 30 during the operation of the air-conditioning device 10.

[0069] In some optional embodiments of the present application, such as Figure 6 As shown, the learning control device 20 can also continuously update the learned and stored operation instructions during the use of the air conditioning device 10. The learning control device 20 can execute the following Figure 6 The air conditioning control unit 100 obtains the air conditioning device 10 in the standby state (such as Figure 6 Try to establish a communication connection with the air supply device 30 (such as Figure 6 As shown in step S411); determine whether the communication connection is successful (such as Figure 6 As shown in step S412 in the figure), if the communication connection is unsuccessful, the attempt to establish a communication connection with the air supply device 30 is maintained; when the communication connection is successful, the initial operation instruction (such as the initial operation instruction of the infrared remote controller 301 of the air supply device 30) of the air supply device 30 is read from the air supply device storage unit 302. Figure 6 As shown in step S413); learning and storing the read initial operation instruction (such as Figure 6 As shown in step S414), such as high wind operation instructions and medium wind operation instructions; performing power-off protection on the learned and stored initial operation instructions (such as Figure 6 As shown in step S415); obtaining the air conditioning device 10 in the running state (such as Figure 6 The initial operation instruction is selected as the matching operation instruction and outputted to the infrared receiving unit 300 through the infrared transmitting unit 200 to control the operation of the air supply device 30, for example, according to the actual heat load of the air-conditioned room (such as Figure 6 If the user thinks that the use effect is not good during this process, for example, the wind speed is reduced because the user thinks that the wind speed is too cold, the learning control device 20 reads the auxiliary operation instructions of the air supply device infrared remote controller 301 to the air supply device 30 from the air supply device storage unit 302 (such as Figure 6 As shown in step S418); performing power-off protection on the learned and stored auxiliary operation instructions (such as Figure 6 As shown in step S419, it is preferred to end the power-off protection of the initial operation instruction at the same time; select the auxiliary operation instruction as the matching operation instruction and output it to the infrared receiving unit 300 through the infrared transmitting unit 200 to control the operation of the air supply device 30 (such as Figure 6 As shown in step S420 in the flowchart, the iterative learning and updating of the operation instructions are realized.

[0070] In some optional embodiments of the present application, the learning control device 20 may also selectively set a temperature acquisition unit, which detects the changes in the room temperature of the air-conditioned room caused by the different operating instructions learned and saved, so as to facilitate the learning control device 20 to select matching operating instructions according to the actual heat load of the air-conditioned room.

[0071] The air supply device 30 has different functions, for example, some electric fans have a swing air supply function, while some electric fans do not have a swing air supply function. To achieve identification, the learning control device 20 is further configured to obtain the available functions of the air supply device 30 by polling after establishing a communication connection with the air supply device 30. Figure 7 As shown, the learning control device 20 outputs a broadcast signal to try to establish a communication connection (such as Figure 7 As shown in step S51, the air supply device 30 responds and establishes a communication connection (such as Figure 7 As shown in step S52, the learning control device 20 sends polling requests to the air supply device 30 one by one according to the preset full-function code list (such as Figure 7 As shown in step S53 in the figure), for example, the functions of power on (function instruction code 01), high wind (function instruction code 02), medium wind (function instruction code 03), low wind (function instruction code 04), swing air supply (function instruction code 05), stop swing air supply (function instruction code 06) and power off (function instruction code 00) are sent one by one in the order; after each polling request is sent, it is determined whether a function instruction of the air supply device 30 is received within the set polling period; after receiving the function instruction of the air supply device 30, a one-to-one correspondence between the air supply device 30 and the function instruction is established (such as Figure 7 After the polling cycle ends and the function instruction of the air supply device 30 is not received, a one-to-one correspondence between the air supply device 30 and the function instruction is not established (such as Figure 7 After receiving the function instruction of the air supply device 30 or setting the polling cycle to end, the next round of polling request is sent until the function code polling on the preset full function code list ends (such as Figure 7 As shown in step S56); learning and storing the available functions of the air supply device 30 (such as Figure 7 As shown in step S57), that is, all one-to-one correspondences between the air supply device 30 and the function instructions are stored.

[0072] As mentioned above, the air supply structure of the indoor unit can adopt a wall-mounted air supply structure, that is, it has a return air outlet arranged above the shell and an air supply outlet arranged below the shell; a floor-standing air supply structure, that is, it has an air supply outlet arranged above the shell and return air outlets arranged on the left and right sides below the shell. The return air outlets of these two most common air supply structures are both located in relative corners, and the air flow is uneven, which leads to the temperature sensor installed at the return air outlet for detecting the real-time temperature of the air-conditioned room often having inaccurate measurement problems. In some embodiments of the present application, this problem can be solved by the air supply device 30. Specifically, the learning control device 20 is configured to perform the following steps: Figure 8 The multiple steps shown are as follows: the selected matching operation instruction is output to the infrared receiving unit 300 through the infrared transmitting unit 200 to control the operation of the air supply device 30 (such as Figure 8 The real-time temperature of the air-conditioned room is read from the air-conditioning control unit 100 (eg Figure 8 The target setting temperature of the air-conditioned room is read from the air-conditioning control unit 100 (eg Figure 8 Calculate the temperature difference between the real-time temperature and the target set temperature (as shown in step S63); Figure 8 As shown in step S64); determine that the temperature difference between the real-time temperature and the target set temperature is reduced to a set range (such as Figure 8 When the temperature difference between the real-time temperature and the target set temperature is reduced to the set range, the wind speed intervention operation instruction is output to the infrared receiving unit 300 through the infrared transmitting unit 200 to increase the rotation speed of the air supply device 30, thereby increasing the return air flow rate flowing into the return air outlet of the air conditioner 10 (such as Figure 8 As shown in step S66 in the figure, the detection accuracy of the temperature sensor at the return air outlet is improved to make the compressor run more smoothly and avoid frequency fluctuations near the target set temperature. Fig. 9 and Fig.10 A schematic diagram of the control effect of the wind speed intervention operation command is given, which increases the air volume F1 (shown by the thinner legend F1 in state S1) to the air volume F2 (shown by the thicker legend F2 in state S2).

[0073] In some optional embodiments of the present application, the air conditioning system 1 further includes an image processing device 40. Fig.11As shown, the image processing device 40 is configured to output the wind direction data of the air supply device 30 to the learning control device 20 when the air conditioner 10 is in operation and the air supply device 30 is operating according to the matching operation instruction output by the infrared signaling unit 200. The image processing device 40 includes at least one camera device or image acquisition device and a graphics processing unit (GPU), and can recognize the wind direction data of the air supply device 30 including the air supply direction through the acquired image of the air supply device 30. The recognition algorithm can be implemented based on a convolutional neural network, such as a common CNN or Yolo algorithm, etc., which is not the focus of protection of this application and will not be further introduced here.

[0074] Matching the image processing device 40, in some embodiments of the present application, the learning control device 20 is configured to perform the following Fig.12 The multiple steps shown are as follows: the selected matching operation instruction is output to the infrared receiving unit 300 through the infrared transmitting unit 200 to control the operation of the air supply device 30 (such as Fig.12 The real-time temperature of the air-conditioned room is read from the air-conditioning control unit 100 (eg Fig.12 The target setting temperature of the air-conditioned room is read from the air-conditioning control unit 100 (eg Fig.12 Calculate the temperature difference between the real-time temperature and the target set temperature (as shown in step S73); Fig.12 As shown in step S74); determine that the temperature difference between the real-time temperature and the target set temperature is reduced to a set range (such as Fig.12 When the temperature difference between the real-time temperature and the target set temperature is reduced to the set range, the wind speed intervention operation instruction is output to the infrared receiving unit 300 through the infrared transmitting unit 200 to increase the rotation speed of the air supply device 30, and increase the return air flow rate from the return air outlet of the air conditioner 10 (such as Fig.12 At the same time, the wind direction intervention operation instruction is output to the infrared receiving unit 300 through the infrared transmitting unit 200 so that the wind direction data covers the location of the air conditioner 10, and the wind speed intervention operation instruction is output to the infrared transmitting unit 200 so that the wind direction data covers the location of the air conditioner 10 (such as Fig.12 As shown in step S77 in the figure, the detection accuracy of the temperature sensor at the return air outlet is improved to make the compressor run more smoothly and avoid frequency fluctuations near the target set temperature.

[0075] The above intervention control is transient control. In some embodiments of the present application, the learning control device 20 also performs the following steps: Fig.13 Additional steps as shown. Fig.13As shown in step S78, it is determined whether the temperature difference between the real-time temperature and the target set temperature is maintained within the target range (for example, less than 1°C and maintained for several minutes); when the temperature difference between the real-time temperature and the target set temperature is maintained within the target range, the wind direction intervention instruction and the wind speed intervention instruction are stopped (for example, Fig.13 (as shown in step S79).

[0076] In some embodiments of the present application, Fig.14 As shown, the air conditioning system 1 further includes a lighting device 50. The lighting device 50 has an adjustable lighting angle. The learning control device 20 is configured to control the lighting device 50 to start and make the lighting angle cover the position of the air supply device 30 when the air conditioning device 10 is in operation, the air supply device 30 operates according to the matching operation instruction output by the infrared signaling unit 200, and the image processing device 40 outputs the wind direction data of the air supply device 30 to the learning control device 20. The lighting device 50 is used to fill in the light for the camera device or image acquisition device in the image processing device 40, ensuring that the image processing device 40 can obtain clear and processable images.

[0077] In some optional embodiments of the present application, the learning control device 20, the image processing device 40 and the lighting device 50 are arranged in the air conditioning device 10. The user can start and stop the lighting device 50 by himself through the air conditioning control terminal 101, and use the lighting device 50 as a light.

[0078] Electric fans, air purifiers, dehumidifiers and other devices with air supply functions are all movable. If the position is changed, the auxiliary regulation effect on the air-conditioned room will change, and the linkage control effect with the air-conditioning device 10 will also change. If the learning control device 20 is still designed to use the same matching operation instructions for control after the position of the air supply device 30 changes, the auxiliary regulation effect will deviate from the control target. To overcome this problem, in some optional embodiments of the present application, the learning control device 20 performs the following Fig.15 The multiple steps shown are: obtaining, by the air conditioning control unit 100, that the air conditioning device 10 is in a standby state (such as Fig.15 As shown in step S810); try to establish a communication connection with the air supply device 30 (such as Fig.15 As shown in step S811); determine whether the communication connection is successful (such as Fig.15 As shown in step S812 in the figure, if the communication connection is unsuccessful, the attempt to establish a communication connection with the air supply device 30 is maintained; when the communication connection is successful, the initial operation instruction (such as the initial operation instruction of the infrared remote controller 301 of the air supply device to the air supply device 30) is read from the air supply device storage unit 302. Fig.15 As shown in step S813); learning and storing the read initial operation instruction (such as Fig.15As shown in step S814), such as high wind operation instructions and medium wind operation instructions; performing power-off protection on the learned and stored initial operation instructions (such as Fig.15 As shown in step S815); obtaining the air conditioning device 10 in the running state (such as Fig.15 The initial operation instruction is selected as the matching operation instruction and outputted to the infrared receiving unit 300 through the infrared transmitting unit 200 to control the operation of the air supply device 30, for example, according to the actual heat load of the air-conditioned room (such as Fig.15 If the user thinks that the use effect is not good during this process, for example, the wind speed is reduced because the user thinks that the wind speed is too cold, the learning control device 20 reads the auxiliary operation instructions of the air supply device infrared remote controller 301 to the air supply device 30 from the air supply device storage unit 302 (such as Fig.15 As shown in step S818); performing power-off protection on the learned and stored auxiliary operation instructions (such as Fig.15 As shown in step S819, it is preferred to simultaneously end the power-off protection of the initial operation instruction; select the auxiliary operation instruction as the matching operation instruction and output it to the infrared receiving unit 300 through the infrared transmitting unit 200 to control the operation of the air supply device 30 (such as Fig.15 As shown in step S820); determine whether the image processing device 40 can output the wind direction data of the air supply device 30 to the learning control device 20 (such as Fig.15 As shown in step S821 in the figure, if the wind direction data of the air supply device 30 can be output to the learning control device 20, no operation is performed; if the wind direction data of the air supply device 30 can no longer be output to the learning control device 20, it means that the air supply device 30 has moved, and the power-off protection of the auxiliary operation instruction is ended. When the operation is performed again, it is performed according to the initialization operation (such as Fig.15 In some other optional implementations, the power-off protection may be temporarily retained, and after powering on again, it is determined whether the image processing device 40 can output the wind direction data of the air supply device 30 to the learning control device 20. If so (for example, the user sends the air supply device 30 for cleaning or it temporarily fails), the power-off protection is retained; if the wind direction data of the air supply device 30 cannot be output to the learning control device 20, the power-off protection is terminated, and the operation is performed according to the initialization when the operation is performed again.
