Technical Field

[0001] This invention relates to the field of smart home appliances and the Internet of Things, and in particular to an information transmission method, system and storage medium based on air supply disturbance. Background Technology

[0002] With the increasing prevalence of smart home and IoT technologies, information interaction between indoor smart devices (such as bedside control terminals, smart nightlights, and curtain actuators) is becoming more frequent. Currently, these devices typically rely on traditional wireless communication links such as Wi-Fi, Bluetooth, and Zigbee for information transmission. These methods are clearly applicable to devices that require continuous network connectivity or high-speed two-way interaction.

[0003] However, in home environments, there are many terminals that only need to receive simple short commands or wake-up signals. These terminals typically transmit only a small amount of bit information, such as power on / off signals, mode switching, or scene triggering. If these low-power terminals are still required to maintain a complete wireless receiving link online for extended periods, it would significantly increase their standby power consumption, hardware costs, and network configuration complexity. Summary of the Invention

It should also be understood that the term “and / or” as used in this specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes such combinations.

[0015] Please see Figure 1 , Figure 1 This is a flowchart illustrating the information transmission method based on air supply disturbance provided in an embodiment of the present invention. This method can be applied to smart home systems, superimposing micro-disturbance signals to transmit control information while the air conditioner is supplying air normally. This can reduce the standby power consumption of the target device and improve its anti-interference capability. Figure 1 As shown, the method includes steps S100 to S140.

[0016] S100, the air conditioner generates control information to be sent and determines whether the current operating status meets the preset communication window conditions.

[0017] In this embodiment of the invention, the control information can be generated by the air conditioner itself, a home smart gateway, a scene controller, or a cloud server. Its content typically includes the target address, command type (such as switch, mode switching, scene trigger), command parameters, and frame number. The preset communication window condition refers to the time interval during which the airflow is sufficiently stable and the physical prerequisites for code transmission are met under the current operating conditions of the air conditioner. Only when this condition is met will the micro-perturbation signal superimposed on the airflow not undergo severe distortion and will not affect the air conditioner's primary environmental regulation task.

[0018] After generating control information, it's necessary to determine whether the current operating status meets the preset communication window conditions. This ensures that the operating status won't change significantly over a period of time, preventing signal distortion or interference with the air conditioner's main task. The air conditioner's main task refers to the task the air conditioner is currently performing, such as cooling mode and maintaining the temperature at 26°C. Because the air conditioner's fan speed and air deflector angle constantly change with temperature control requirements during operation, sending codes during periods of drastic fluctuation in operating conditions can easily lead to signal distortion or affect the air conditioner's main task. Therefore, the communication window conditions must be checked before sending codes.

[0019] Once the current operating status is confirmed to meet the preset window access conditions, subsequent tasks can be executed, thereby ensuring the compatibility of communication behavior with the main air conditioning task and guaranteeing the physical transmission quality of perturbation signals from the source.

[0020] In some embodiments, such as in the embodiments of the present invention, step S110 includes determining whether one or more of the following conditions are met: The change in the fan speed of the air conditioner within a preset time window is lower than a preset change threshold. The angle of the air guide plate of the air conditioner is within the coverage area of ​​the target device; The air conditioner is not in the initial high air volume stage, rapid cooling stage, strong air supply stage, defrosting stage, fault protection stage, or gear shifting stage.

[0021] In this embodiment of the invention, the preset time window is typically set to 1 to 5 seconds. Through the above multi-dimensional condition judgment, the system can select a calm period suitable for airflow perturbation modulation. If any of the above key conditions are not met, the air conditioner will cache the control information to be sent in a non-volatile queue and delay sending it until the next communication window that meets the conditions.

[0022] For example, assuming a preset time window of 3 seconds, if the fan speed spikes from 500 RPM to 1200 RPM within 3 seconds when the user first turns on the air conditioner and it's in strong cooling mode, exceeding the preset threshold, the air conditioner will buffer and delay sending control information. Alternatively, if the user has enabled user settings such as "clean airflow" or "disable communication interference" in their smart terminal application, the system will also determine that the conditions are not met. However, if the air conditioner has been running for 2 hours and is operating at a stable low fan speed, with a speed fluctuation of less than 10 RPM within 3 seconds, the air deflector blowing evenly and covering the bed area, and the user has not enabled communication interference disabling settings, then the preset communication window conditions are met, and code transmission is allowed. After confirming that the current operating state meets the preset window conditions, subsequent tasks can be executed, thus ensuring the compatibility of communication behavior with the air conditioner's main tasks and guaranteeing the physical transmission quality of the perturbation signal from the source.

[0023] In addition to the three conditions mentioned above, it is also possible to determine whether the user has set to allow superimposed perturbations. If allowed, it is considered to meet the preset window communication conditions. If not allowed, it is considered not to meet the preset window communication conditions. Alternatively, it can be determined whether the expected perturbation amplitude will cause significant changes in body perception. For example, when the change in air volume is large, it will cause significant changes in body perception, and it is considered not to meet the preset window communication conditions.

[0024] S110, if the current operating state of the air conditioner meets the preset communication window conditions, the air conditioner establishes a reference wind field and encodes the control information into a supply air disturbance frame.

[0025] In this embodiment of the invention, the reference wind field refers to the relatively stable airflow state formed within the target area without superimposed communication disturbances. It serves as a dynamic reference baseline for subsequent determination of the presence of disturbance signals, rather than a fixed absolute wind speed value. The purpose of establishing a reference wind field is to eliminate the differences in absolute wind speed caused by different rooms, different installation distances, and different wind speed settings, enabling the target device to make adaptive judgments based on relative changes, thereby completely solving the misjudgment problem caused by fixed thresholds.

[0026] Specifically, the air conditioner maintains its current fan speed and air deflector angle, continuously collecting data for a preset reference time (preferably 1s to 5s) to establish a stable reference wind field within the target area. During this period, the target device collects local airflow signals, calculates the reference mean, reference fluctuation range, and noise statistics (such as background standard deviation), and determines a dynamic judgment threshold accordingly. The dynamic judgment threshold is a threshold calculated in real-time based on the statistical characteristics of the reference wind field, used to distinguish between normal environmental airflow fluctuations and deliberately emitted perturbation signals. Preferably, the dynamic judgment threshold can be set to the reference mean plus a predetermined relative increment, or to 2 to 4 times the reference mean plus the background standard deviation; this threshold can cover 95% to 99.7% of normal background fluctuations.

[0027] After establishing the baseline wind field, the control information is encoded into air supply disturbance frames. The purpose of encoding the control information into air supply disturbance frames is to give the disordered airflow changes a structured protocol semantics, enabling the target device to perform preamble synchronization, address addressing, data error correction, and deduplication, thus elevating simple physical wind blowing into reliable data communication.

[0028] In some embodiments, such as in the embodiments of the present invention, the air supply disturbance frame includes a preamble segment, an address segment, a command segment, a sequence number segment, a check segment, and an end segment arranged in sequence; wherein, the preamble segment is used to wake up the target device and establish synchronization, the address segment is used to identify the target device, the command segment is used to indicate the action type, the sequence number segment is used to distinguish adjacent commands and prevent repeated execution, the check segment is used for error detection, and the end segment is used to indicate the end of this frame.

[0029] In this embodiment of the invention, the air supply disturbance frame may include a preamble, an address segment, a command segment, a sequence number segment, a check segment, and an end segment arranged in sequence. The preamble is used to wake up the target device and establish synchronization, and may use an alternating disturbance sequence such as "1010" or "11001100". The address segment is used to identify the target device, such as a bedside control terminal, lighting terminal, purification terminal, or the logical address of a designated area. The command segment indicates the action type, such as night mode, turning off the prompt sound, reducing brightness, or waking up the communication link. The sequence number segment is used to distinguish adjacent commands and prevent duplicate execution. The check segment is used for error detection and may use parity check, cumulative check, or CRC check. The end segment indicates the end of the frame and may use a continuous, undisturbed time window or a specified end code.

[0030] For example, assuming the air conditioner remains in its current state for 2 seconds, the bedside terminal calculates a baseline mean of 0.2 m / s and a background standard deviation of 0.02 m / s. With a system setting coefficient of 3, the dynamic judgment threshold is 0.26 m / s. This means that only when the airflow velocity exceeds 0.26 m / s is it considered a valid perturbation signal. Assuming a "turn on the night light" command is to be sent, the encoded airflow perturbation frame consists of the following segments: a preamble "10101010" for wake-up, the address segment for the night light's MAC address, a command segment indicating the turn-on action, a sequence number segment to prevent repeated execution, a CRC check segment, and an end segment indicating 2 seconds of no perturbation.

[0031] S120, the air conditioner fine-tunes the air supply parameters of the reference wind field according to the air supply disturbance frame to output multiple perturbation symbols.

[0032] In this embodiment of the invention, a perturbation symbol refers to the smallest identifiable airflow disturbance unit generated by the air conditioner through the air supply system within a preset symbol time window, used to carry a symbolic information (such as a binary "0" or "1"). The amplitude of the perturbation symbol must be less than the human body's sensory threshold, but greater than the sensor's detection threshold.

[0033] By converting digitized protocol frames into airflow changes in the physical world that can be detected by sensors, analog-to-digital conversion and physical modulation are achieved. By fine-tuning the airflow parameters, a balance can be found between ensuring that the airflow is detectable by sensors and that it is imperceptible to the human body. This allows information to be discreetly embedded in the existing airflow without affecting user comfort or the effectiveness of air conditioning temperature control, thus achieving seamless communication.

[0034] In some embodiments, such as in embodiments of the present invention, as Figure 2 As shown, step S120 includes steps S121-S123.

[0035] S121, using the current stable air supply volume as the benchmark air volume, and the preset duration as the code period; S122, within the symbol period, if the fan speed or air volume increases by a preset air volume increment relative to the reference air volume and continues to reach a predetermined proportion of the symbol period, then a perturbation symbol representing the first symbol value is output. S123, if the reference air volume or change is kept below the determination threshold, then a perturbation symbol representing the second symbol value is output.

[0036] In this embodiment of the invention, steps S121-S123 are binary amplitude modulation. The symbol period is preferably set to 300ms to 1500ms, the preset airflow increment is preferably set to 5% to 25% of the rated airflow, and a protection interval of 100ms to 500ms is set between adjacent symbols to reduce residual crosstalk from airflow.

[0037] In addition to binary amplitude modulation, air guide angle modulation can also be used, which keeps the fan speed constant and causes the air guide plate to shift slightly by 2° to 10° near the reference angle. This is particularly suitable for the silent mode at night and avoids low-frequency noise caused by motor speed change.

[0038] In addition, rhythmic modulation can be used, which generates different numbers of short pulses or disturbances of different durations within a symbol period. Its function is to significantly improve the distinguishability through frequency domain characteristics when the background air volume is large.

[0039] Meanwhile, the air conditioner's fine-tuning of air supply parameters is limited by a comfort constraint mechanism. The system determines the maximum allowable modulation amplitude based on the current fan speed, target temperature difference, night mode status, the area where the user is located, airflow direction, and user settings. Its function is to prioritize the air conditioner's primary task when comfort constraints conflict with communication reliability. For example, in a daytime living room scenario, the air conditioner is in normal air supply mode, the system uses binary amplitude modulation, a symbol period of 500ms, and an airflow increment of 15%, so the user hardly notices any fluctuation in airflow. When in normal air supply mode or when the target device is far from the air conditioner, the disturbance amplitude can be appropriately increased or composite rhythm modulation can be used to improve signal arrival rate. In a nighttime bedroom scenario, the air conditioner is in sleep / silent mode, the system triggers comfort constraints, disabling fan speed changes and instead using airflow angle modulation, with the air guide vane only slightly deflected by 3°, and the symbol period lengthened to 1000ms. If the user has just turned on the air conditioner and the indoor temperature difference is large, the system determines that comfort constraints conflict with communication, directly suspends code transmission, and prioritizes cooling.

[0040] S130, the target device obtains the perturbation code by acquiring the airflow signal containing the perturbation code, and obtains the air supply disturbance frame based on the perturbation code.

[0041] In this embodiment of the invention, the target device (such as a bedside control terminal, night light, curtain actuator, air purification terminal or low power sensing node) has a built-in airflow sensing unit. Depending on the cost and sensitivity requirements of the device, a thermal wind speed sensor, differential pressure sensor, thermal element or miniature wind pressure diaphragm can be selected.

[0042] By introducing a dual-state reception mechanism, the standby power consumption of the target device can be reduced: it maintains low-power listening at the microwatt level most of the time to capture wake-up signals, and only wakes up the main control chip to perform high-frequency sampling and decoding when a valid signal is confirmed.

[0043] In some embodiments, such as in embodiments of the present invention, as Figure 3 As shown, step S130 includes steps S131-S132.

[0044] S131, the target device, in a low-power listening state, collects airflow signals at a first sampling frequency and detects whether there is a preamble that matches the preamble of the air supply disturbance frame; S132, if the preamble is detected, the target device enters the complete decoding state, increases the sampling frequency to the second sampling frequency, divides the sampling signal into time windows according to the symbol period, and extracts the signal features within each symbol time window to recover the perturbation symbol.

[0045] In this embodiment of the invention, the first sampling frequency is preferably 1Hz to 5Hz. In this state, the main control chip is in a sleep state, and only the sensor and comparator work, so the power consumption of the device can be reduced to the microwatt level.

[0046] The second sampling frequency is preferably between 20Hz and 100Hz. The extracted signal features include one or more of the following: average amplitude, peak amplitude, duration, slope of change, or number of pulses. For example, a smart night light has a built-in low-cost thermal element that is normally in a low-power listening state, sampling once every 0.5 seconds (first sampling frequency 2Hz), with power consumption in the microwatt range. When the air conditioner blows out a preamble causing a slight airflow fluctuation, the night light detects the matching template, instantly waking up the main control MCU to enter full decoding mode and increasing the sampling rate to 50Hz (second sampling frequency). The MCU calculates the average amplitude within each 500ms symbol window and compares it with the previously calculated dynamic threshold (e.g., 0.26m / s), successfully decoding the subsequent address and command segments.

[0047] S140, the target device parses the air supply disturbance frame to obtain the control information.

[0048] In this embodiment of the invention, after the target device obtains the air supply disturbance frame, it extracts each field according to the protocol structure and performs strict security and reliability checks to determine whether to execute the corresponding control action or discard the invalid frame.

[0049] Because the indoor airflow environment is extremely complex (with uncontrollable interference such as people walking around and doors and windows opening and closing), the system employs multiple defenses, including address filtering, verification and comparison, serial number deduplication, and abnormal environment discarding. Its core function is to completely block false triggers and malfunctions caused by environmental interference, ensuring that only legal, correct, non-repeating, and environmentally stable valid commands can be executed, thereby guaranteeing the system's extremely high reliability.

[0050] In some embodiments, such as in embodiments of the present invention, as Figure 4 As shown, the method further includes steps S150-S153.

[0051] S150, the target device judges the parsed address field, check field and frame sequence number; S151, if the address does not match, the verification fails, or the frame sequence number is the same as the executed command, the current air supply disturbance frame is discarded. S152, if the address matches, the verification passes, and the frame sequence number is not repeated, then the action corresponding to the control information is executed.

[0052] In this embodiment of the invention, to further improve robustness in complex environments, an abnormal environment discard mechanism is introduced. During the decoding process, if a reference wind field is detected to continuously drift unidirectionally beyond a preset drift threshold during the transmission of a frame (e.g., continuous movement of people or sudden opening of doors and windows), the pulse interval significantly deviates from the protocol range, or the number of symbols is inconsistent with the preset frame length, then the current environment is determined to be unstable or the signal incomplete, and the decoding of the current air supply disturbance frame is actively abandoned. Its function is to prevent uncontrollable drastic changes in the natural environment from being misinterpreted as control signals, leading to malfunctions.

[0053] Simultaneously, a tiered repeated verification mechanism can be introduced. For ordinary commands, execution can proceed after a single successful verification; however, for critical commands involving safety or high priority (such as closing a gas valve), the same command must be received 1 to 3 times within a preset deduplication time window (preferably 5 to 60 seconds), and execution will only proceed after each verification result is completely consistent. Its purpose is to reduce the probability of erroneous actions in high-risk operations to an extremely low level.

[0054] Furthermore, a regional addressing mechanism can be implemented using the airflow direction, swing coverage area, or air supply coverage window of the air conditioner. This allows for the transmission of air supply disturbance frames containing different addresses to target devices in different locations or areas. Each target device only responds to air supply disturbance frames that match its own regional address or terminal logical address. This enables independent control of multiple devices at the physical space level, eliminating the need for complex network configuration. The air supply disturbance frames can also be used as a low-power wake-up channel. Target devices normally completely disable high-power Wi-Fi or Bluetooth modules. Only after decoding and confirming the wake-up command do they activate the corresponding modules to perform subsequent large-scale data interactions with the gateway. This significantly reduces overall standby power consumption while maintaining communication bandwidth.

[0055] For example, if a user suddenly opens a window halfway through decoding, causing the indoor airflow baseline to drift beyond a threshold, the nightlight will detect the abnormal environment and immediately abandon the current frame to prevent accidental light activation. If the control information is to close the smart gas valve, the system requires that the command be received twice consecutively within 10 seconds and verified to be completely identical before execution. In the living room, when the air conditioner is oscillating left and right, it sends the left area address code when the air deflector is oscillating towards the left sofa area and the right area address code when oscillating towards the right dining table area. The floor lamp next to the sofa and the aromatherapy diffuser next to the dining table only listen to their respective addresses and do not interfere with each other. The smart speaker with a screen normally has its Wi-Fi module off. It only turns on its Wi-Fi module to receive the firmware upgrade package after receiving the airflow wake-up frame sent by the air conditioner. After the upgrade is completed, it sends back the upgrade success result via Wi-Fi and then turns its Wi-Fi off again.

[0056] In some embodiments, such as in embodiments of the present invention, as Figure 5 As shown, the method further includes steps S160-S161.

[0057] S160, the air conditioner determines the maximum allowable modulation range according to preset comfort constraints; S161, when the air conditioner fine-tunes the air supply parameters according to the air supply disturbance frame, it uses the maximum allowable modulation amplitude as a limiting condition to output multiple of the micro-disturbance symbols.

[0058] In this embodiment of the invention, the preset comfort constraints refer to a series of limiting rules set on the intensity, frequency, and duration of airflow disturbances to ensure user comfort indoors and the normal execution of the main task of air conditioning environment regulation. The maximum permissible modulation amplitude is the maximum physical change (such as the maximum percentage increase in maximum airflow or the maximum deflection angle of the air guide vane) that the system calculates and can be superimposed on the reference wind field under the current specific environment and operating state. The function of the air conditioner in determining the maximum permissible modulation amplitude based on the preset comfort constraints is to dynamically assess the tolerance of the current environment to the user's comfort.

[0059] Specifically, preset comfort constraints can include at least one of the following: current fan speed, target temperature difference, night mode status, the area where the person is located, airflow direction, and user preferences. For example, when the air conditioner is at a high fan speed, the base wind speed is relatively high, and the absolute value of the allowable airflow increment can be appropriately increased; when the target temperature difference (i.e., the difference between the current indoor temperature and the set temperature) is large, it indicates that the air conditioner is in a high-load temperature adjustment phase, and the modulation range should be strictly limited at this time; when in night mode or silent mode, users are extremely sensitive to noise and airflow changes, and the maximum allowable modulation range will be significantly compressed; if infrared or radar detects that a person is in the direct airflow area of ​​the air deflector, the system will also actively tighten the modulation limit to avoid discomfort caused by direct cold or hot air blowing.

[0060] After confirming the maximum permissible modulation amplitude, the air conditioner uses this as a constraint to output multiple perturbation symbols when fine-tuning the air supply parameters based on the air supply disturbance frame. This transforms the calculated theoretical upper limit into a safety boundary for actual physical execution, ensuring that the output of each perturbation symbol is within a safe range that is imperceptible or minimally perceptible. By forcibly intercepting any excessive modulation commands that might cause discomfort at the physical execution level, the system achieves a perfect dynamic balance between communication reliability and user comfort.

[0061] For example, in a daytime living room scenario, the air conditioner is in normal airflow mode with a small target temperature difference, and the maximum permissible modulation amplitude confirmed by the system is relatively large (e.g., airflow increase can reach 20%). When the air conditioner outputs perturbation symbols, it uses a larger amplitude and a shorter symbol period to quickly complete information transmission, so the user sitting on the sofa can hardly feel the airflow fluctuations. However, in a nighttime bedroom scenario, the air conditioner is in sleep silent mode with the air deflector facing the headboard area, and the maximum permissible modulation amplitude confirmed by the system is extremely small (e.g., airflow increase limited to within 5%, or only allowing the air deflector to deflect 3°). In this case, when the air conditioner outputs perturbation symbols, it uses a smaller amplitude and a longer symbol period (e.g., 1000ms). Although the single-frame transmission time is longer, it ensures that the user will not be awakened by wind noise or airflow changes while sleeping.

[0062] Furthermore, when comfort constraints and communication reliability severely conflict, the system triggers a priority degradation mechanism. For example, if the user has just turned on the device and the indoor temperature difference is extreme (e.g., 35°C indoors in summer, set to 20°C), the system determines that the current rapid cooling primary task has a much higher priority than the communication task. In this case, the system limits the maximum allowable modulation amplitude to 0, that is, it actively delays transmission or reduces the transmission frequency until the room temperature approaches the set value and the air conditioner enters a stable operating phase. Then, it recalculates and resumes the output of perturbation symbols, thereby always ensuring that the air conditioning primary task and the user's comfort are not negatively affected.

[0063] The information transmission method based on air supply disturbance disclosed in this invention can generate control information and establish a reference wind field when the current operating state meets the preset communication window conditions. Then, the control information is encoded into an air supply disturbance frame, and the air supply parameters of the reference wind field are fine-tuned according to the air supply disturbance frame to output multiple micro-disturbance symbols. The target device obtains the micro-disturbance symbols by collecting airflow signals, thereby obtaining the air supply disturbance frame. The air supply disturbance frame is then parsed to obtain control information and execute corresponding instructions. Short instruction transmission can be completed using existing air supply capabilities without affecting the main air conditioning task and user comfort, significantly reducing the standby power consumption of the target device and improving the identification reliability in complex indoor air field environments.

[0064] Figure 6 This is a schematic block diagram of an information transmission system 200 based on air supply disturbance provided in an embodiment of the present invention. Figure 6 As shown, corresponding to the above-described information transmission method based on air supply disturbance, the present invention also provides an information transmission system 200 based on air supply disturbance. This information transmission system 200 includes a unit for executing the above-described information transmission method based on air supply disturbance. Specifically, please refer to... Figure 6 The information transmission system 200 based on air supply disturbance includes a first generation unit 201, a first establishment unit 202, a first output unit 203, a first acquisition unit 204, and a first parsing unit 205.

[0065] The first generation unit 201 generates control information to be sent by a computer device and determines whether the current operating status meets the preset communication window conditions. The first establishment unit 202 is used to establish a reference wind field and encode the control information into a wind disturbance frame if the current operating state of the computer device meets the preset communication window conditions. The first output unit 203 is used by the computer device to fine-tune the air supply parameters of the reference wind field according to the air supply disturbance frame in order to output multiple perturbation symbols.
