[0016] Please see Figure 1 , Figure 1 This is a flowchart illustrating a control method for an air conditioner according to an embodiment of the present invention. The control method for the air conditioner will be described in detail below. Figure 1 As shown, the method includes the following steps S110-S120.

[0017] S110. Obtain personnel activity status information and control the air conditioner to enter energy-saving mode based on the personnel activity status information.

[0018] In this embodiment of the invention, the air conditioner includes a millimeter-wave radar module, an oxygen generation module, a control module, a communication module, an air quality detection module, and the air conditioner itself. The millimeter-wave radar module operates at a 60GHz frequency, emitting high-frequency electromagnetic waves and receiving reflected signals. It analyzes the presence of people indoors using the Doppler effect and echo intensity. This module is installed near the air conditioner's air outlet and can detect the presence and activity of people indoors in real time. The oxygen generation module, integrated inside the air conditioner, releases an appropriate amount of oxygen when air quality deteriorates, improving indoor air freshness. The oxygen generation module uses molecular sieve technology or water electrolysis to generate oxygen. The control module processes the collected data and controls the operating modes of the air conditioner and the oxygen generation module. The communication module enables the air conditioner to connect to a home LAN or the internet, achieving two-way communication with user terminals. User terminals include devices such as remote controls, tablets, and mobile phones. Users can use these terminals to send control commands to the air conditioner, set system parameters, and view the air conditioner's operating status in real time. The air quality detection module is used to detect air quality information; the air conditioner itself includes traditional air conditioning components such as a compressor, fan, and heat exchanger, and performs basic functions such as cooling, heating, and air supply under the instructions of the control module. All modules work together to achieve intelligent control, energy-saving operation, and improved air quality in the air conditioner.

[0019] It should be noted that in this embodiment, a millimeter-wave radar module can be used to emit high-frequency electromagnetic waves. By analyzing the Doppler effect and echo intensity of the reflected signal, information such as the presence of movement and even breathing frequency of people can be detected to obtain information on their activity status. In other embodiments, the millimeter-wave radar module can be replaced by a combination of an infrared pyroelectric sensor and camera image recognition to detect the status of people indoors and obtain information on their activity status. Specifically, the infrared sensor is used to initially determine whether anyone is present, while the camera uses image recognition to further determine the number of people and their activity status to obtain information on their activity status. It should also be noted that the combination of infrared pyroelectric sensors and camera image recognition has the advantage of low cost and is suitable for scenarios where privacy requirements are not high.

[0020] It should also be noted that in this embodiment, if the millimeter-wave radar module detects a single moving target, it is determined to be a single-person usage scenario, meaning there is only one person present; if multiple moving targets are detected, it is determined to be a multi-person scenario, meaning there are at least two people present; if no moving target is detected within a set time, it is determined to be unoccupied, meaning there are no people present. When it is determined to be unoccupied, the control module switches the air conditioner to energy-saving mode, which includes a first energy-saving mode, a second energy-saving mode, and a third energy-saving mode.

[0021] In this embodiment, such as Figure 2 As shown, step S110 specifically includes steps S111-S113: S111. If the personnel activity status information is detected to be that there are no personnel, then within a first preset time period, the air conditioner is controlled to enter the first energy-saving mode. S112. During a second preset time period following the first preset time period, control the air conditioner to enter the second energy-saving mode; S113. During a third preset time period following the second preset time period, control the air conditioner to enter the third energy-saving mode.

[0022] In this embodiment of the invention, when the millimeter-wave radar detects that the personnel activity status information is "no personnel present," the control module will initiate a segmented energy-saving control strategy based on the duration of vacancy. This strategy aims to balance energy-saving effects with the comfort needs of users upon their return. Specifically, during the first preset time period (e.g., 30 minutes) after the vacancy status is determined, the air conditioner is controlled to enter the first energy-saving mode, which achieves initial energy saving while maintaining basic air circulation. Specifically, if the difference between the current set temperature and the ambient temperature is detected to be small, the air conditioner will be controlled to shut down the compressor with the highest energy consumption, allowing only the indoor fan to run continuously at the lowest speed. This maintains a slight flow of indoor air, avoiding complete stagnation, and reduces the overall operating power consumption of the air conditioner, effectively reducing energy waste caused by short periods of vacancy. If the vacancy status continues and enters the second preset time period (e.g., 30 minutes to 120 minutes), the air conditioner is controlled to switch to the second energy-saving mode. This mode employs a more economical periodic intermittent operation strategy. For example, within a cycle (e.g., 30 minutes), the compressor and fan are only controlled to run for a short 5 minutes to maintain stable pipe pressure and a basic indoor temperature environment. For the remaining 25 minutes, the compressor and fan are completely shut down. This "run-stop-run" intermittent method, compared to continuous low-speed airflow, can significantly reduce energy consumption, making it suitable for scenarios where users are away for extended periods. When the unattended state continues and enters the third preset time period (e.g., exceeding 120 minutes), it is determined that the user has been away for an extended period, and the air conditioner is immediately switched to the third energy-saving mode, i.e., a completely off mode. In this mode, the air conditioner automatically shuts down all major functional components (including the compressor and fan), retaining only the standby circuit to maintain a minimum sensing capability. At this time, overall power consumption can be controlled at an extremely low level. Once the millimeter-wave radar module or other linked devices (such as smart door locks) detect a return signal, the air conditioner is immediately and automatically woken up, quickly returning to the user-preset normal operating mode, ensuring that the user can promptly regain a comfortable environment upon their return.

[0023] S120. Obtain air quality information, and control the air conditioner to produce oxygen based on the personnel activity status information and the air quality information.

[0024] In this embodiment of the invention, air quality information is acquired, including PM2.5 concentration, carbon dioxide concentration, and oxygen concentration. Specifically, in this embodiment, the air quality module detects PM2.5, carbon dioxide, and oxygen concentrations. The air quality detection module integrates a laser scattering PM2.5 sensor, a non-dispersive infrared carbon dioxide sensor, and an electrochemical oxygen sensor. It detects PM2.5 concentration using the laser scattering principle, measures carbon dioxide concentration using infrared absorption characteristics, and determines oxygen concentration based on an electrochemical reaction, thereby achieving simultaneous monitoring of multiple parameters. After acquiring the air quality information, the air conditioner is controlled to produce oxygen based on the personnel activity status information and the air quality information.

[0025] In this embodiment, such as Figure 3 As shown, step S120 specifically includes steps S121-S124: S121. Detect the number of people in the personnel activity status information; S122. If at least two of the aforementioned personnel are detected, then determine whether the oxygen production conditions are met based on the air quality information. S123. If the oxygen production conditions are met, control the air conditioner to produce oxygen based on the air quality information; S124. If only one person is detected, then the step of controlling the air conditioner to produce oxygen based on the air quality information is executed.

[0026] In this embodiment of the invention, the activity status information of people indoors is continuously analyzed and detected. When at least two people are detected indoors, the system further determines whether the current environment meets the preset oxygen production conditions based on air quality information. If so, the control module will activate and adjust the working mode and oxygen output of the oxygen production module integrated inside the air conditioner to quickly improve the air pollution problem caused by multiple people gathering. If only one person is detected indoors, there is no need to perform the specific condition judgment for the multiple-person scenario, and the program will directly jump to the step of controlling the operation of the oxygen production module based on air quality information. In this single-person scenario, air quality parameters are still continuously monitored, and an on-demand oxygen supply strategy is adopted to achieve the best balance between comfort and energy saving. This differentiated control logic based on the number of people aims to ensure that the indoor air environment remains healthy and comfortable under any circumstances, while minimizing energy waste.

[0027] Furthermore, such as Figure 4As shown, step S122 specifically includes steps S1221-S1222: S1221, if the PM2.5 concentration exceeds a preset PM2.5 concentration or the carbon dioxide concentration exceeds a preset carbon dioxide concentration, then the oxygen production conditions are determined to be met; S1222, if the PM2.5 concentration does not exceed the preset PM2.5 concentration and the carbon dioxide concentration does not exceed the preset carbon dioxide concentration, then the oxygen production conditions are determined not to be met. It should be noted that in this embodiment, the oxygen production conditions are determined based on the PM2.5 concentration and carbon dioxide concentration. Specifically, when multiple people are detected indoors, an oxygen production condition judgment is performed. Specifically, a preset PM2.5 concentration threshold (e.g., 50 μg / m³) is set. 3 Using a preset PM2.5 concentration and a preset carbon dioxide concentration threshold (e.g., 800 ppm) as evaluation benchmarks, in multi-person scenarios, the system compares the current indoor PM2.5 concentration with the preset PM2.5 concentration and the carbon dioxide concentration with the preset carbon dioxide concentration in real time. If either the PM2.5 concentration or the carbon dioxide concentration exceeds the preset PM2.5 concentration, it indicates that the current indoor air quality no longer meets the requirements for health and comfort, and oxygen production is immediately activated. Conversely, if neither the PM2.5 nor the carbon dioxide concentration exceeds the preset PM2.5 concentration, the current air quality is considered to be within an acceptable healthy range, and oxygen production is not activated. In this case, the oxygen production module will remain in standby or low-power operation to avoid unnecessary energy consumption and will continue to monitor air quality.

[0028] Furthermore, such as Figure 5As shown, step S123 specifically includes steps S1231-S1233: S1231, obtaining the oxygen concentration and comparing it with a preset oxygen concentration; S1232, if the oxygen concentration is less than the preset oxygen concentration, reducing the oxygen output flow rate of the air conditioner; S1233, if the oxygen concentration is not less than the preset oxygen concentration, controlling the air conditioner to supply oxygen in pulses. It should be noted that in this embodiment, the real-time indoor oxygen concentration is continuously obtained and compared with a preset oxygen concentration (e.g., 82%) as the basis for control decisions. When the current oxygen concentration is detected to be less than the preset oxygen concentration, the operation of reducing the oxygen output flow rate of the air conditioner is executed. For example, the oxygen flow rate is adjusted from a higher 5L / min to 3L / min. This adjustment aims to slow down the oxygen output rate, allowing the oxygen generation module more sufficient adsorption time, thereby improving the purity of the produced oxygen and more effectively improving the indoor low-oxygen condition. Conversely, when the oxygen concentration is detected to be no less than the preset oxygen concentration, the system switches to a more energy-efficient pulse oxygen supply mode. In this mode, oxygen supply is not continuous, but rather an intermittent, on-demand supply strategy is adopted. This maintains the indoor oxygen concentration within the ideal comfort range while significantly optimizing energy efficiency and avoiding excessive oxygen supply.

[0029] Furthermore, such as Figure 6 As shown, step S1233 specifically includes steps S1234-S1235: S1234, when a person is detected inhaling, the solenoid valve in the air conditioner is controlled to open to release oxygen; S1235, after a preset time has elapsed since the solenoid valve opened, the solenoid valve is closed to stop releasing oxygen. Specifically, to achieve precise oxygen supply and reduce energy consumption, a pulse oxygen supply strategy synchronized with the user's breathing is adopted. Specifically, when a person is detected inhaling, the control module immediately sends a high-level pulse signal to the solenoid valve in the air conditioner. After the solenoid valve coil is energized, it generates electromagnetic force, attracting the valve core to move upward, thereby quickly opening the valve channel and starting to release high-concentration oxygen into the indoor environment. After the valve opens, a precise timer is started. After a very short preset time (e.g., 50 milliseconds), the control module cuts off the power supply to the solenoid valve coil. The valve core automatically resets under the action of the internal spring force, closing the valve and thus precisely cutting off the oxygen flow. This pulse-based control, which involves "detection-on-delay-off," can efficiently deliver oxygen to the user's inhalation flow, ensuring effective oxygen supply while minimizing the waste of oxygen during ineffective periods such as exhalation.

[0030] In summary, through intelligent sensing and precise control, significant improvements have been achieved in energy saving and health and comfort of air conditioners, specifically in the following two aspects: First, precise energy saving and reduced ineffective energy consumption: By monitoring the activity status of people indoors in real time, it can accurately identify unoccupied scenarios and initiate phased, progressive energy-saving strategies (such as gradually transitioning from low-speed airflow to complete shutdown). This effectively avoids the energy waste caused by the continuous operation of traditional air conditioners in unoccupied states, maximizing energy efficiency.

[0031] Secondly, dynamic oxygen supply enhances comfort: It intelligently links the number of people (e.g., distinguishing between single-person and multi-person scenarios) with air quality information (air quality information includes PM2.5 concentration, carbon dioxide concentration, and oxygen concentration); when it detects that the gathering of multiple people leads to an increase in carbon dioxide and PM2.5 concentrations and a decrease in oxygen concentration, it automatically activates the oxygen generation module and dynamically adjusts the indoor oxygen level through on-demand supply strategies such as pulse oxygen supply, significantly improving the air freshness and comfort in multi-person scenarios and creating a healthier indoor environment for users.

If the PM2.5 concentration does not exceed the preset PM2.5 concentration and the carbon dioxide concentration does not exceed the preset carbon dioxide concentration, then the oxygen production conditions are not met.

[0036] In some embodiments, such as this one, the second control unit 202 is further configured to: Obtain the oxygen concentration and compare it with a preset oxygen concentration; If the oxygen concentration is less than the preset oxygen concentration, then reduce the oxygen output flow rate of the air conditioner; If the oxygen concentration is not less than the preset oxygen concentration, then the air conditioner is controlled to supply oxygen in pulses.
