[0022] To more clearly illustrate the technical solutions in this application or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

Detailed Implementation
[0024] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0025] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0026] The operating principle of the air conditioner involved in the embodiments of this application is described in detail below: The compressor compresses the refrigerant and delivers it through pipes to the condenser. The high-temperature, high-pressure gaseous refrigerant releases heat in the condenser, transforming into a medium-temperature, high-pressure liquid refrigerant. This medium-temperature, high-pressure liquid refrigerant then passes through a capillary tube (throttling unit) to reduce its pressure, becoming a low-temperature, low-pressure liquid refrigerant. This low-temperature, low-pressure liquid refrigerant is then delivered to the evaporator, where it evaporates into a gas, absorbing a significant amount of heat during the evaporation process. Finally, the low-temperature, low-pressure gaseous refrigerant in the evaporator is delivered to the compressor to participate in the next cycle. When the air conditioner is cooling, the outdoor unit's heat exchanger acts as the condenser, and the indoor unit's heat exchanger acts as the evaporator; conversely, when the air conditioner is heating, the outdoor unit's heat exchanger acts as the evaporator, and the indoor unit's heat exchanger acts as the condenser.
[0027] In related technologies, user state perception can be achieved through the following schemes, each with its own advantages and disadvantages: 1. Infrared sensing scheme: detects the presence of a human body using infrared waves. Advantages: fast response, easy installation, and low cost. Disadvantages: short detection distance, no penetration capability, and can only detect moving human bodies. 2. Centimeter-wave scheme: detects the presence of a human body using centimeter-level microwaves. Advantages: fast response and ability to sense changes in human movement. Disadvantages: requirements for installation height and angle, and inability to detect stationary human bodies. 3. Millimeter-wave scheme: detects the presence of a human body using millimeter-level microwaves. Advantages: fast response, high detection accuracy, and ability to detect slightly moving human bodies. Disadvantages: requirements for installation height and angle, and high cost. 4. Thermal imaging scheme: works by detecting infrared radiation emitted by objects. Advantages: can sense the presence and location of a human body and detect temperature changes. Disadvantages: at long distances, temperature affects the detection results.
[0028] Of the above solutions, the first two cannot detect stationary human bodies and are susceptible to interference from pets in the home. While millimeter-wave imaging can detect near-stationary human bodies with slight movements, it requires multiple integrated judgment devices for installation, and its high cost hinders widespread adoption. Thermal imaging, due to its detection principle, is vulnerable to hacking attacks that could easily leak user information.
[0029] To address the aforementioned technical problems in related technologies, embodiments of this application provide a comprehensive sensing technology that utilizes existing sensors in the device for user-state perception. For example... Figure 1 As shown, the air conditioner 101 in this embodiment includes an environmental sensor 102 for detecting carbon dioxide concentration and a wireless unit 103 disposed on the wired controller. By utilizing the WiFi version of the air conditioner's wired controller (including the aforementioned wireless unit) and the air conditioner's carbon dioxide sensor, accurate user status can be achieved.
[0030] In this embodiment, a WiFi wired controller is used because wired controllers are typically installed near the entrance of a room, at a height of 1.4 meters and facing the entire space, which allows for better transmission and reception of wireless signals. The carbon dioxide sensor can be installed normally in the airflow path of the space.
[0031] The control method based on comprehensive sensing technology provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.
[0032] like Figure 2 As shown in the embodiment of this application, a control method based on comprehensive sensing technology is provided, which may include the following steps 201 to 203: Step 201: Obtain wireless signal parameters through the wireless unit and carbon dioxide concentration parameters through the environmental sensor.
[0033] For example, the wireless unit installed on the air conditioner can be used to monitor the signal strength and frequency changes of the wireless network signal in the current indoor environment in real time, and the carbon dioxide sensor installed on the air conditioner can be used to monitor the carbon dioxide concentration changes in the current indoor environment in real time.
[0034] Step 202: Determine the fluctuation of the wireless signal based on the wireless signal parameters, and determine the change in carbon dioxide concentration based on the carbon dioxide concentration parameters. Based on the fluctuation of the wireless signal and the change in carbon dioxide concentration, determine the state of the human body.
[0035] For example, the state of a human body can be determined based on the analysis of changes in wireless signals and changes in carbon dioxide concentration.
[0036] Specifically, step 202 above, the step of determining the wireless signal fluctuation situation, may further include any one of the following steps 202a1 to 202a3: Step 202a1: If the wireless signal parameters indicate that the signal strength of the wireless signal received by the wireless unit is less than the first fluctuation threshold, then the fluctuation of the wireless signal is determined to be no fluctuation.
[0037] Step 202a2: If the signal strength and / or frequency fluctuation of the wireless signal received by the wireless unit are greater than or equal to the first fluctuation threshold and less than the second fluctuation threshold, the fluctuation of the wireless signal is determined to be a small fluctuation.
[0038] Step 202a3: If the signal strength and / or frequency fluctuation of the wireless signal received by the wireless unit, as indicated by the wireless signal parameters, are greater than or equal to the second fluctuation threshold, the fluctuation of the wireless signal is determined to be a large fluctuation.
[0039] It's understandable that when a human body enters the transmission range of a wireless signal, it absorbs some of the signal energy, thus reducing the signal strength. Simultaneously, the human body reflects and scatters the signal, altering its propagation direction and generating echo signals. By monitoring and analyzing these changes, it's possible to determine whether a human body is nearby.
[0040] It's understandable that the strength of a normal Wi-Fi signal is usually quite stable, while the strength of an echo signal generated by human interference can fluctuate significantly. A normal Wi-Fi signal originates from a router or wireless network device, while an echo signal is a signal reflected back from a transmitted signal. The frequency of an echo signal may vary because it has undergone reflection and refraction, while the frequency of a normal signal is relatively stable. Echo signals also have a time delay, as they need time to travel from the transmission point to the reflection point and back to the receiving point. Based on these differences, the presence of a human can be determined.
[0041] Specifically, step 202 above, the step of determining the carbon dioxide fluctuation situation, may further include any one of the following steps 202b1 to 202b5: Step 202b1: If the carbon dioxide concentration parameter indicates that the increase in the current environmental carbon dioxide concentration within a preset time period is less than a first change threshold, then the carbon dioxide concentration change is determined to be no change.
[0042] Step 202b2: If the carbon dioxide concentration parameter indicates that the increase in the current environment's carbon dioxide concentration within a preset time period is greater than or equal to the first change threshold and less than the second change threshold, then the change in carbon dioxide concentration is determined to be a slight increase.
[0043] Step 202b3: If the carbon dioxide concentration parameter indicates that the rate of increase of the current environmental carbon dioxide concentration within a preset time period is less than the first rate threshold, then the change in carbon dioxide concentration is determined to be a gradual increase.
[0044] Step 202b4: If the carbon dioxide concentration parameter indicates that the rate of increase of the current environmental carbon dioxide concentration within a preset time period is greater than or equal to the first rate threshold and less than the second rate threshold, then the change in carbon dioxide concentration is determined to be a multiple increase.
[0045] Step 202b5: If the carbon dioxide concentration parameter indicates that the rate of decrease of the current environmental carbon dioxide concentration within a preset time period is greater than or equal to the third rate threshold, then the change in carbon dioxide concentration is determined to be a gradual decrease.
[0046] It's understandable that when someone is present in a space, their exhaled CO2 continuously increases the CO2 concentration within that space. Tests have shown that an adult can raise the CO2 concentration by 400-500 ppm. Based on this, changes in wireless signals can be used to determine the presence of a human.
[0047] Specifically, based on the changes in the wireless signal and the changes in carbon dioxide concentration, the step of determining the state of human presence in step 202 may include any one of the following steps 202c1 to 202c5: Step 202c1: When the fluctuation of the wireless signal is no fluctuation and the change of carbon dioxide concentration is no change, the human body's presence state is determined to be the first unmanned state.
[0048] Step 202c2: When the fluctuation of the wireless signal is small and the change of carbon dioxide concentration is small, determine that the human body is in the second unmanned state.
[0049] Step 202c3: When the wireless signal fluctuation is large and the carbon dioxide concentration gradually increases, the human body presence state is determined to be the first human presence state.
[0050] Step 202c4: When the wireless signal fluctuation is described as having no fluctuation and the carbon dioxide concentration changes by the described multiple, the state of the human body is determined to be the second "personned" state.
[0051] Step 202c5: When the wireless signal fluctuation is described as having no fluctuation and the carbon dioxide concentration changes as described as gradually decreasing, the state of the human body is determined to be the third unmanned state.
[0052] For example, based on the changes in the aforementioned wireless signal and the changes in carbon dioxide concentration, the state of human presence can be determined as shown in Table 1 below.
[0053] Table 1 As shown in Table 1 above, by combining the changes in wireless signals and carbon dioxide concentration under different conditions, various human physical states can be determined, and the air conditioner can be controlled based on the determination results.
[0054] Step 203: Determine the corresponding target control strategy based on the human body's state, and control the air conditioner based on the target control strategy.
[0055] For example, the target control strategies corresponding to different human body states are not exactly the same, and step 203 above may specifically include any one of the following steps 203a1 to 203a5: Step 203a1: When the human body is in the first unmanned state, the first control strategy is determined as the target control strategy.
[0056] Step 203a2: When the human body is in the second unmanned state, the second control strategy is determined as the target control strategy.
[0057] Step 203a3: When the human body is in the first human presence state, the third control strategy is determined as the target control strategy.
[0058] Step 203a4: When the human body is in the second human presence state, the fourth control strategy is determined as the target control strategy.
[0059] Step 203a5: When the human body is in the third unmanned state, the fifth control strategy is determined as the target control strategy.
[0060] The first control strategy includes: controlling the air conditioner to standby or low-frequency heat preservation; the second control strategy includes: controlling the air conditioner to standby or low-frequency heat preservation; the third control strategy includes: controlling the air conditioner to operate normally; the fourth control strategy includes: controlling the air conditioner to operate in silent mode; and the fifth control strategy includes: controlling the air conditioner to standby or low-frequency heat preservation.

[0062] The control method based on comprehensive sensing technology provided in this application first acquires wireless signal parameters through the wireless unit and carbon dioxide concentration parameters through the environmental sensor. Then, it determines the fluctuation of the wireless signal based on the wireless signal parameters and the change in carbon dioxide concentration based on the carbon dioxide concentration parameters. Based on the fluctuation of the wireless signal and the change in carbon dioxide concentration, it determines the presence state of the human body. Finally, it determines a corresponding target control strategy based on the presence state of the human body and controls the air conditioner based on the target control strategy. In this way, accurate identification of the user's state is achieved through the detection of wireless signals and carbon dioxide concentration, and intelligent control of the device is performed based on the identification results.
