[0058] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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 some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0059] Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0060] First read Figure 1 , Figure 1 This is a schematic diagram of the air conditioning linkage system according to an embodiment of the present invention. The air conditioning linkage system according to an embodiment of the present invention includes a first air conditioner 1, a second air conditioner 2, a wireless router 3, and a smart terminal 4.

[0061] The first air conditioner 1 is located within the first space 11 and is used to regulate the temperature of the micro-environment of the first space 11. The second air conditioner 2 is located within the second space 21 and is used to regulate the temperature of the macro-environment of the second space 21. The first space 11 is located within the second space 21 and is not an enclosed space, allowing for heat exchange with the second space 21 through air.

[0062] The first air conditioner 1, the second air conditioner 2, and the smart terminal 4 are all connected to the wireless router 3 via Wi-Fi. Through the wireless router 3, data can be exchanged between the first air conditioner 1 and the second air conditioner 2, between the first air conditioner 1 and the smart terminal 4, and between the second air conditioner 2 and the smart terminal 4. Furthermore, users can set relevant parameters for the first air conditioner 1 and the second air conditioner 2 through the smart terminal 4 (e.g., a smartphone app).

[0063] It should be noted that the wireless data communication method of the air conditioning linkage system of the present invention is not limited to Wi-Fi networks. Those skilled in the art can use short-range wireless communication methods such as Bluetooth, ZigBee, and LoRa, depending on the actual situation. Furthermore, the data interaction between the first air conditioner 1 and the second air conditioner 2 can be achieved through… Figure 1 The router 3 shown is used for this purpose. In other embodiments, it can also be directly paired and connected for data interaction in a direct connection manner.

[0064] Preferably, in this embodiment, the first air conditioner 1 is a pet air conditioner, the second air conditioner 2 is an indoor air conditioner, the first space 11 is a pet house with a pet air conditioner, and the second space 21 is the indoor space where the user lives. The pet house is in an open or semi-open form and is placed inside the indoor space; compared to the indoor space, the pet house is relatively small, therefore the ambient temperature of the pet house is greatly affected by the ambient temperature of the indoor space.

[0065] Continue reading Figure 2 , Figure 2 This is a flowchart illustrating the main steps of the air conditioning linkage method according to an embodiment of the present invention. Figure 2 As shown, the air conditioning linkage method of this invention includes:

[0066] Step S201: Obtain the first ambient temperature, the second ambient temperature, the first target temperature, the second target temperature, and the status of the second air conditioner;

[0067] Step S202: Control the first air conditioner based on at least one of the first ambient temperature, the second ambient temperature, the first target temperature, the second target temperature, and the state of the second air conditioner.

[0068] In step S201, the first ambient temperature is the pet house ambient temperature, which can be measured by the temperature sensor of the pet air conditioner; the second ambient temperature is the indoor ambient temperature of the user's house, which can be measured by the temperature sensor of the indoor air conditioner. The first target temperature is the suitable ambient temperature for the pet set by the user through the smart terminal 4 based on factors such as pet type and season, and can also be called the pet house target temperature. The second target temperature is the suitable ambient temperature for the user's indoor space set by the user through the smart terminal 4, and can also be called the indoor target temperature. The pet air conditioner can obtain the real-time status of the indoor air conditioner through a wireless Wi-Fi network, including status information such as whether it is turned on and whether the current operating mode is cooling or heating. Furthermore, the pet air conditioner can obtain data such as indoor ambient temperature and indoor target temperature through data communication with the indoor air conditioner.

[0069] In step S202, the air conditioning controller of the pet air conditioner controls the pet air conditioner (first air conditioner 1) to turn on or off, and the working state after it is turned on, based on at least one of the acquired pet house ambient temperature (first ambient temperature), indoor ambient temperature (second ambient temperature), preset pet-suitable ambient temperature (first target temperature), preset user-suitable indoor ambient temperature (second target temperature), and the status of the indoor air conditioner (second air conditioner 2).

[0070] Next, combine Figure 3This document details the specific control flow of step S202. In this embodiment of the invention, the pet air conditioner also incorporates a millimeter-wave radar sensor, which can detect whether a pet is inside the pet house. As shown in the figure, when a pet leaves the pet house and the duration of no pet in the pet house is greater than or equal to a second time threshold, the pet air conditioner is kept off for energy-saving purposes. When the pet returns to the pet house and the continuous stay time of the pet in the pet house is greater than or equal to a first time threshold, the linkage method of the pet air conditioner described in step S202 is executed. As an example, the first time threshold can be set to 30 seconds, and the second time threshold can be set to 60 seconds. Those skilled in the art can also set the values ​​of the first and second time thresholds according to actual conditions. By combining the detection results of the pet in the pet house with the method described in step S202, the pet air conditioner can be turned on or off more selectively, achieving energy-saving goals more effectively.

[0071] In step S202, it is first determined whether the indoor ambient temperature is within the suitable temperature range for pets, that is, whether the indoor ambient temperature is greater than or equal to the first suitable lower limit value and less than or equal to the first suitable upper limit value. The first suitable lower limit value and the first suitable upper limit value are usually set according to the preset suitable ambient temperature for pets (target temperature of the pet house). For example, when the target temperature of the pet house is 25℃, 25℃±3℃ can be set as the first suitable lower limit value and the first suitable upper limit value, respectively. The first suitable upper limit value is greater than the first suitable lower limit value.

[0072] Since the temperature in a pet house is usually greatly affected by the indoor temperature, when the indoor temperature is suitable for the pet, it can be assumed that the temperature in the pet house is basically the same as the indoor temperature and also suitable for the pet. In this case, regardless of whether the indoor air conditioning is on, there is no need to turn on the pet air conditioner. This avoids both the pet air conditioner and the indoor air conditioning being running simultaneously, thus reducing energy consumption, as the indoor temperature is within the pet's comfortable range.

[0073] When the indoor temperature is outside the suitable temperature range for pets, i.e., the indoor temperature is lower than the first suitable room temperature lower limit or higher than the first suitable room temperature upper limit, check the status of the indoor air conditioner and control the pet air conditioner accordingly.

[0074] If the indoor air conditioning is off, turn on the pet air conditioning and control it to work according to the preset cooling or heating mode, thereby creating a suitable ambient temperature for the pet in the pet house space.

[0075] If the indoor air conditioning is on, then the pet air conditioning is further controlled based on the pet house ambient temperature, indoor ambient temperature, pet house target temperature, and indoor target temperature.

[0076] The first temperature adjustment trend is derived based on the ambient temperature and the target temperature of the pet house. When the target temperature of the pet house is higher than the ambient temperature, the first temperature adjustment trend is an increasing trend; when the target temperature of the pet house is lower than the ambient temperature, the first temperature adjustment trend is a decreasing trend.

[0077] Similarly, a second temperature control trend is derived based on the indoor ambient temperature and the indoor target temperature. When the indoor target temperature is higher than the indoor ambient temperature, the second temperature control trend is a warming trend; when the indoor target temperature is lower than the indoor ambient temperature, the second temperature control trend is a cooling trend.

[0078] When the primary and secondary temperature control trends differ, the pet air conditioner operates independently, following a preset cooling or heating mode to maintain the target temperature within the pet house. For example, in the penguin exhibit at an animal showroom, the ideal temperature for penguins is below -2°C, resulting in a lower target temperature for the pet house. However, the indoor visitor area in the same space should not be too cold. During certain times in winter, the pet air conditioner may need to cool to maintain the lower temperature in the pet house, while the indoor air conditioning may need to heat to provide a more comfortable indoor environment for visitors. In this case, the pet air conditioner and the indoor air conditioning operate independently according to their respective temperature control modes and target temperatures.

[0079] When the first and second temperature control trends are the same—that is, both are either rising or falling—the pet air conditioner is controlled based on the target temperature difference between the target temperature of the pet house and the target temperature of the indoor space. The target temperature difference is calculated as follows:

[0080] Target temperature difference = |Target temperature in pet house - Target temperature in indoor space|

[0081] When the target temperature difference is greater than or equal to the target temperature difference threshold, it indicates that the suitable ambient temperature for the pet is significantly different from the target room temperature set by the user. In this case, in order to provide a comfortable pet house environment temperature for the pet, the pet air conditioner can be set to be turned on independently, cooling or heating according to the preset target temperature of the pet house.

[0082] When the target temperature difference is less than the target temperature difference threshold, it indicates that the difference between the pet's suitable ambient temperature and the user-set target room temperature is small. Considering that most pets are highly adaptable to ambient temperature, even if the pet house's ambient temperature deviates slightly from the pet's most suitable ambient temperature, it will not cause the pet much discomfort. At this time, the user can choose different control strategies based on the actual situation. If the user prioritizes energy saving, they can choose to turn off the pet air conditioner and use the indoor air conditioner to achieve a comfortable temperature in the pet house. If the user wants to quickly achieve a comfortable environment in the pet house while also saving energy, they can choose to turn on both the pet air conditioner and the indoor air conditioner simultaneously, controlling the pet air conditioner based on the indoor ambient temperature and the target indoor temperature. Figure 4 As shown, Figure 4 This document outlines the detailed flow steps for controlling a pet air conditioner based on the indoor ambient temperature and the target indoor temperature.

[0083] The indoor ambient temperature is measured at the sampling interval t set by the system (which is also the control cycle of the pet air conditioner), and the room temperature control difference T between the current indoor ambient temperature and the preset indoor target temperature is calculated.

[0084] T = Indoor target temperature - Indoor ambient temperature

[0085] Preferably, an incremental PID algorithm is used to calculate the incremental base number ΔI of the control current in the nth control cycle of the pet air conditioner. n , △I n The method for obtaining it is as follows:

[0086] △I n =K p (T n -T n-1 )+K i T n +K d (T n -2*T n-1 +T n-2 )

[0087] Among them, K p K i and K d T is the preset PID calculation coefficient. n Let be the room temperature control difference for the nth control cycle, where n ≥ 2.

[0088] The control current I of the pet air conditioner in the nth control cycle n The calculation method is as follows:

[0089] I n =I n-1 -A*|△I n |

[0090] Where A is the preset control gain coefficient, and A is a positive number greater than 0.

[0091] In the first two control cycles when the pet air conditioner starts cooling or heating, the initial control currents I0 and I1 are the same. As an example, the maximum operating current value of the pet air conditioner can be set to the initial control currents I0 and I1 according to the operating level of the pet air conditioner.

[0092] byI n The calculation method can be used to obtain the control current I of the pet air conditioner. n It gradually decreases; the larger the value of A, the smaller the value of I. n The faster the temperature decreases, the better. Therefore, the control gain coefficient A can be set according to the actual conditions of the pet space and indoor space, as well as the user's intention to achieve greater energy efficiency. For example, when the ambient temperature of the pet house responds quickly to changes in the indoor ambient temperature, and the user considers both pet comfort and energy saving, A can be set to a value greater than 1, such as A = 2.

[0093] It should be noted that the parameter K in the incremental PID algorithm p K i and K d All values ​​are less than 1, and the optimal value can be obtained through a large number of experiments. The method of obtaining relevant parameters through experiments is a well-known technique to those skilled in the art, and will not be elaborated here.

[0094] Once the pet-friendly air conditioner starts cooling or heating based on the indoor ambient temperature and target indoor temperature, it will turn off after preset conditions are met. Users can set different preset conditions to turn off the pet-friendly air conditioner according to their actual needs.

[0095] In this embodiment, preferably, when the control current I of the pet air conditioner n When the operating current is less than or equal to the control current threshold, the pet air conditioner should be turned off. For example, the control current threshold can be set to 20% of the initial I0 value. When the operating current of the pet air conditioner is less than or equal to 20% of the initial I0 value, the indoor temperature has usually stabilized. As the operating current of the pet air conditioner decreases, its environmental regulation effect on the pet house becomes weaker. At this time, for energy saving, the pet air conditioner can be turned off, and the indoor air conditioner can continue to regulate the environmental temperature of the user's house and the pet house.

[0096] In another embodiment, the target temperature for the pet is lower than the target temperature for the room. When both the pet air conditioner and the room air conditioner are in heating mode, the ambient temperature of the pet house will first reach the preset target temperature for the pet. At this time, the pet air conditioner does not need to continue heating, so the pet air conditioner can be turned off.

[0097] It should be noted that the indoor air conditioner will continue to heat according to the target indoor temperature, making the pet house environment temperature slightly higher than the target temperature. However, as mentioned earlier, considering that pets usually have a certain degree of adaptability to environmental temperature, even though the pet house environment is already higher than the target temperature, the pet air conditioner does not need to be turned on for cooling, but should remain off.

[0098] In another embodiment, the target temperature for the pet is higher than the target temperature for the indoor space. When both the pet air conditioner and the indoor air conditioner are in heating mode, the indoor ambient temperature will first reach the preset target temperature, and the indoor air conditioner will then be in standby or operating at low power to maintain the target temperature. Since the pet's space and the indoor space are connected, when the temperature in the pet's house is high, heat from the pet's space will escape into the indoor space. Therefore, the pet air conditioner will require more electricity to reach the set target temperature for the pet's house. Similarly, considering that pets typically have a certain degree of environmental adaptability, for energy conservation, the pet air conditioner is turned off, and the indoor air conditioner is used to maintain both the pet's house and the indoor space at the target temperature.

[0099] In another embodiment, the target temperature for the pet is lower than the target temperature for the indoor air conditioner. When both the pet air conditioner and the indoor air conditioner are in heating mode and the indoor ambient temperature rises rapidly, similarly, for energy-saving considerations, the user can set the pet air conditioner to be turned off when the indoor ambient temperature is greater than or equal to the first suitable lower limit of room temperature.

[0100] In another embodiment, if the target temperature for the pet is higher than the target temperature for the indoor air conditioner, and both the pet air conditioner and the indoor air conditioner are in cooling mode, and the indoor ambient temperature drops rapidly, similarly, for energy-saving considerations, the user can set the pet air conditioner to be turned off when the indoor ambient temperature is less than or equal to the upper limit of the first suitable room temperature.

[0101] It should be noted that those skilled in the art can also employ one or more combinations of other technical solutions, such as infrared sensors and image sensors, to detect pets inside the pet house. Furthermore, the sensor used to detect pets can be either a sensor built into the pet air conditioner or a standalone sensor installed inside the pet house, as long as the sensor data can be acquired by the pet air conditioner.

[0102] It should be noted that the data interaction between the various devices in the air conditioning linkage system of the embodiments of the present invention can also be achieved through wired communication methods, such as Ethernet, RS485 bus, CAN bus, etc.; or through a combination of wired and wireless networks. Those skilled in the art can select the appropriate device networking method according to the actual situation.

The pet air conditioner memory can be configured to store program code that executes the air conditioning linkage method of the above method embodiments. This program code can be loaded and run by the pet air conditioner processor to implement the above air conditioning linkage method.

[0104] In another embodiment, the air conditioning linkage system further includes a server. The server can be a smart home server on a local network or a cloud server on the internet. The server can interact with the first and second air conditioners via one or more combinations of local wired and / or wireless networks, public networks such as 4G / 5G, etc. Therefore, the server can acquire the first ambient temperature, the second ambient temperature, the first target temperature, the second target temperature, and the status of the second air conditioner, and generate control commands for the first air conditioner based on at least one of these, sending them to the first air conditioner for execution, thereby realizing the air conditioning linkage method of this embodiment of the invention.

[0105] Furthermore, the present invention also provides an air conditioner, such as... Figure 5 The schematic diagram of the air conditioner composition of this embodiment of the invention is shown. The air conditioner 5 includes an air conditioner body 51, a memory 52 and a processor 53.

[0106] The air conditioner unit 51 can perform environmental regulation functions such as cooling and / or heating, and has wireless and / or wired communication capabilities, enabling data interaction with other devices. In some embodiments, the air conditioner unit 51 also has a built-in millimeter-wave radar sensor, which can detect whether there are people, pets, or other targets served by the air conditioner 5 in the space.

[0107] The memory 52 can be configured to store program code for executing the air conditioning linkage method of the above-described method embodiments. This program code can be loaded and run by the processor 53 to implement the air conditioning linkage method.
