[0002] In smart home systems, the needs for remote control and status monitoring are becoming more and more diverse. Traditional remote controllers mainly rely on infrared signals to control devices. In recent years, with the development of wireless communication technology, remote controllers using WiFi modules have gradually entered the market. WiFi remote controllers communicate with home appliances (such as air conditioners) through WiFi networks to achieve functions such as remote control and status synchronization. The pairing of WiFi remote controllers and voice modules of home appliances mainly relies on WiFi detection frame communication technology. The WiFi remote controller sends detection frames, and the voice module of the home appliance receives and responds to these frames to achieve pairing of the WiFi remote controller and the home appliance. However, during the pairing process, due to the wide propagation range of WiFi signals, the WiFi remote controller is easily paired with multiple home appliances within the signal coverage range or multiple home appliances that are close to each other at the same time, resulting in incorrect pairing and affecting the accuracy of pairing. In the prior art, the signal coverage range is reduced by limiting the transmission power of the WiFi remote controller, but the effect is not obvious, because even if the transmission power is reduced, other home appliances nearby may still receive the pairing signal, thereby affecting the accuracy of pairing.

[0031] See also Figure 1 , Figure 1 It is a scene diagram of a WiFi remote control pairing system provided by an embodiment of the present invention. The WiFi remote control pairing system includes a WiFi remote control and a home appliance, wherein the WiFi remote control is provided with a WiFi module, the home appliance is provided with a voice module, the voice module includes the WiFi module, and the WiFi remote control and the home appliance communicate through their respective WiFi modules. Understandably, the home appliance is any device having the voice module, such as an air conditioner. It should be noted that, in this embodiment, the home appliance is always in a pairing state, that is, in a pairing mode, and the WiFi remote control starts the pairing mode by long pressing a combination key, such as pressing "switch" and "mode" at the same time or pressing "power" and "temperature+" at the same time to enter the pairing mode.

[0032] See also Figure 2 , Figure 2 FIG. 1 is a flow chart of a WiFi remote controller pairing method provided by an embodiment of the present invention. The WiFi remote controller pairing method is described in detail below. Figure 2 As shown, the method includes the following steps S110-S140.

[0033] S110. The WiFi remote controller sends a WiFi detection frame to the working environment where it is located, wherein the WiFi detection frame includes pairing request information.

[0034] In the embodiment of the present invention, after the WiFi remote controller and the home appliance enter the pairing mode, the WiFi remote controller sends a WiFi detection frame to the working environment to broadcast its pairing request, wherein the WiFi detection frame includes pairing request information. It should be noted that, in this embodiment, the WiFi detection frame is a management frame sent by the WiFi remote controller, which is used to discover and identify the surrounding WiFi network.

[0035] S120: After receiving the pairing request information, if the requested RSSI value of the pairing request information is within a preset home appliance RSSI threshold range or a dynamic home appliance RSSI threshold range, the home appliance sends a pairing feedback signal to the WiFi remote controller.

[0036] In an embodiment of the present invention, after the household appliance receives the WiFi detection frame, that is, after receiving the pairing request information, the RSSI value of the pairing request information is measured to obtain the requested RSSI value, and the requested RSSI value is determined to be within the preset household appliance RSSI threshold range or the dynamic household appliance RSSI threshold range; if the requested RSSI value is within the preset household appliance RSSI threshold range or the dynamic household appliance RSSI threshold range, a pairing feedback signal is sent to the WiFi remote controller. Understandably, if the requested RSSI value is not within the preset household appliance RSSI threshold range or the dynamic household appliance RSSI threshold range, pairing is stopped, that is, a pairing feedback signal is not sent to the WiFi remote controller. It should be noted that, in this embodiment, the dynamic household appliance RSSI threshold range is determined according to the requested RSSI value and the preset household appliance RSSI threshold range; and the preset household appliance RSSI threshold range is the RSSI threshold range set by the manufacturer when the household appliance leaves the factory, and this threshold range determines the signal strength at which the household appliance will respond to pairing. Understandably, the preset household appliance RSSI threshold range can also be adjusted according to actual needs. It should also be noted that, in the present embodiment, RSSI (Received Signal Strength Indicator) is an indicator for measuring the strength of a wireless signal, usually expressed in negative decibel milliwatts (dBm), and is used to judge the quality of a signal. A higher RSSI value indicates a stronger signal.

[0037] Furthermore, if Figure 3As shown, the dynamic home appliance RSSI threshold range is a step determined according to the requested RSSI value and the preset home appliance RSSI threshold range, including steps S121-S122: S121, real-time monitoring of the requested RSSI value, and detecting whether the threshold adjustment condition is met according to the requested RSSI value; S122, if the threshold adjustment condition is met, the preset home appliance RSSI threshold range is adjusted according to the requested RSSI value through a threshold adjustment algorithm to obtain the dynamic home appliance RSSI threshold range. It should be noted that in this embodiment, the step of detecting whether the threshold adjustment condition is met according to the requested RSSI value includes: if the requested RSSI value changes, it is determined that the threshold adjustment condition is met, wherein the change in the requested RSSI value includes any one of a large fluctuation in the RSSI value, a high rate of change in the RSSI value, and a large average change value of multiple measurements. Specifically, the large fluctuation in the RSSI value means that the requested RSSI value is detected to have a significant fluctuation in a short period of time (for example, within a few seconds), which indicates that the environmental conditions may have changed. The environmental situation refers to the working environment of the home appliance, including surrounding signal interference, obstacles, and the distance between devices. The environmental situation will significantly affect the propagation of the signal and the stability of the pairing process. Signal interference: In the working environment, there may be other WiFi devices, Bluetooth devices or other wireless signal sources, which will interfere with the WiFi signal. Obstacles: Obstacles such as walls, furniture, and metal objects will block or attenuate the WiFi signal and affect the signal strength. For example, when pairing between different rooms, walls may cause signal weakening, thereby affecting the pairing success rate. Distance between devices: The distance between the WiFi remote control and the home appliance will also affect the requested RSSI value and the pairing success rate. Generally, the farther the distance between the devices, the weaker the signal strength and the greater the difficulty of pairing. There are two cases of significant fluctuations in the requested RSSI value: 1. The signal strength is significantly enhanced: This usually means that the interference is reduced, the obstacles are removed, or the distance between the devices is shortened. 2. The signal strength is significantly weakened: This may be due to the emergence of new interference sources, the increase of obstacles, or the distance between the devices. The high rate of change of the RSSI value means that the signal strength increases or decreases rapidly in a short period of time. For example, if the requested RSSI value increases from -60dBm to -40dBm or decreases from -60dBm to -80dBm within a few seconds, this RSSI value change rate may indicate that a new interference source or obstacle has appeared in the environment. The average change value of multiple measurements is large, which means that the requested RSSI value is measured multiple times and its average change range is calculated. If the average change range of the requested RSSI values ​​measured multiple times is large, the home appliance can determine that the environment is unstable.

[0038] It should also be noted that, in this embodiment, the threshold adjustment algorithm includes a low-to-high algorithm, a linear adjustment algorithm, an adaptive algorithm, and a fuzzy control algorithm; the preset home appliance RSSI threshold range is adjusted by the threshold adjustment algorithm according to the requested RSSI value to obtain the dynamic home appliance RSSI threshold range, including: the preset home appliance RSSI threshold range is adjusted by any one or more of the low-to-high algorithm, the linear adjustment algorithm, the adaptive algorithm, and the fuzzy control algorithm to obtain the dynamic home appliance RSSI threshold range. It should be noted that, in this embodiment, the low-to-high algorithm is specifically: if the RSSI value is detected to be much higher than the set RSSI threshold range, the upper limit of the RSSI threshold is increased; if the RSSI value is detected to be much lower than the set RSSI threshold range, the lower limit of the RSSI threshold is lowered. The linear adjustment algorithm is specifically: according to the amplitude and direction of the RSSI value change, the RSSI threshold is linearly increased or decreased, and the adjustment step size can be set according to actual needs. The adaptive algorithm is specifically: not only considering the current RSSI value, but also dynamically adjusting the RSSI threshold according to historical data and the trend of environmental changes. Historical data analysis refers to storing RSSI values ​​over a period of time and analyzing the trend of signal strength changes; environmental change trend prediction refers to predicting the direction of future signal strength changes through analysis of historical data; dynamic adjustment of RSSI threshold refers to dynamic feedback adjustment of RSSI threshold according to current and past RSSI values. The fuzzy control algorithm is designed to deal with uncertainty and ambiguity problems, and is particularly suitable for scenarios where RSSI values ​​fluctuate frequently and the environment is complex. Specifically, fuzzy rules can be set, and fuzzy reasoning can be performed to calculate the specific RSSI threshold that needs to be adjusted. It should also be noted that, in this embodiment, if the RSSI value of the requested RSSI value fluctuates greatly, the preset home appliance RSSI threshold range can be adjusted according to the linear adjustment algorithm to obtain the dynamic home appliance RSSI threshold range; if the RSSI value change rate of the requested RSSI value is high, the preset home appliance RSSI threshold range can be adjusted according to the adjustment algorithm, the linear adjustment algorithm and the adaptive algorithm to obtain the dynamic home appliance RSSI threshold range; if the average change value of multiple measurements of the requested RSSI value is large, the preset home appliance RSSI threshold range can be adjusted according to the linear adjustment algorithm, the adaptive algorithm and the fuzzy control algorithm to obtain the dynamic home appliance RSSI threshold range. It can be understood that different threshold adjustment algorithms can be selected to adjust the preset home appliance RSSI threshold range according to different scenarios and needs to ensure that the WiFi remote control and home appliances can be paired stably and accurately in various environments.

[0039] S130: After the WiFi remote controller receives the pairing feedback signal, if the feedback RSSI value of the pairing feedback signal is within a preset remote control RSSI threshold range or a dynamic remote control RSSI threshold range, the pairing feedback signal is used as an alternative pairing signal.

[0040] In an embodiment of the present invention, after receiving the pairing feedback signal sent by the home appliance, the WiFi remote control measures the RSSI value of the pairing feedback signal to obtain the feedback RSSI value, and determines whether the feedback RSSI value is within the preset remote control RSSI threshold range or the dynamic remote control RSSI threshold range; if the feedback RSSI value is within the preset remote control RSSI threshold range or the dynamic remote control RSSI threshold range, the pairing feedback signal is used as an alternative pairing signal; understandably, if the feedback RSSI value is not within the preset remote control RSSI threshold range or the dynamic remote control RSSI threshold range, the pairing is stopped, that is, the pairing feedback signal is not used as an alternative pairing signal. It should be noted that in this embodiment, the dynamic remote control RSSI threshold range is determined according to the feedback RSSI value and the preset remote control RSSI threshold range; and the preset remote control RSSI threshold range is the RSSI threshold range set by the manufacturer when the WiFi remote control leaves the factory, and this threshold range determines the signal strength at which the WiFi remote control will respond to pairing. Understandably, the preset remote control RSSI threshold range can also be adjusted according to actual needs. It should also be noted that, in this embodiment, the higher the transmission power of the WiFi remote control, the larger the signal coverage range, but it may also increase the risk of mispairing. Generally, the transmission power is limited to 20dBm to reduce the signal coverage range. In the process of implementing the WiFi remote control pairing method, the received pairing feedback signal is filtered at the WiFi remote control end, that is, it is screened, and only the signals within the preset remote control RSSI threshold range or the dynamic remote control RSSI threshold range are processed, which can improve the accuracy of pairing.

[0041] Furthermore, if Figure 4As shown, the dynamic remote control RSSI threshold range is a step determined according to the feedback RSSI value and the preset remote control RSSI threshold range, including steps S131-S132: S131, real-time monitoring of the feedback RSSI value, and detecting whether the threshold adjustment condition is met according to the feedback RSSI value; S132, if the threshold adjustment condition is met, adjusting the preset remote control RSSI threshold range according to the feedback RSSI value through the threshold adjustment algorithm to obtain the dynamic remote control RSSI threshold range. Specifically, the step of detecting whether the threshold adjustment condition is met according to the feedback RSSI value includes: if the feedback RSSI value changes, determining that the threshold adjustment condition is met, wherein the change in the feedback RSSI value includes any one of a large fluctuation in the RSSI value, a high rate of change in the RSSI value, and a large average change value of multiple measurements. According to the feedback RSSI value, the preset remote control RSSI threshold range is adjusted by the threshold adjustment algorithm to obtain the dynamic remote control RSSI threshold range, including: adjusting the preset remote control RSSI threshold range by any one or more of the adjustment algorithm, the linear adjustment algorithm, the adaptive algorithm and the fuzzy control algorithm to obtain the dynamic remote control RSSI threshold range. It should be noted that in this embodiment, the detailed steps of the WiFi remote control detecting whether the threshold adjustment condition is met according to the feedback RSSI value are consistent with the detailed steps of the household appliance detecting whether the threshold adjustment condition is met according to the request RSSI value, which are not repeated here for the sake of simplicity; the detailed steps of the WiFi remote control adjusting the preset remote control RSSI threshold range according to the feedback RSSI value by the threshold adjustment algorithm to obtain the dynamic remote control RSSI threshold range are also consistent with the detailed steps of the household appliance adjusting the preset household appliance RSSI threshold range according to the request RSSI value by the threshold adjustment algorithm to obtain the dynamic household appliance RSSI threshold range, which are not repeated here for the sake of simplicity.

[0042] S140: The WiFi remote controller is paired with the home appliance according to the alternative signal.

[0043] In the embodiment of the present invention, after the WiFi remote controller uses the pairing feedback signal as the candidate pairing signal, it will pair with the home appliance according to the candidate signal. Specifically, Figure 5As shown, step S140 may specifically include steps S141-S142: S141, the WiFi remote controller selects the signal with the largest feedback RSSI value from the alternative pairing signals as the final pairing signal, and uses the home appliance corresponding to the final pairing signal as the target home appliance; S142, the WiFi remote controller pairs with the target home appliance. It should be noted that in this embodiment, the WiFi remote controller selects the home appliance corresponding to the largest feedback RSSI value from the alternative pairing signals as the target home appliance for pairing, which can further improve the accuracy of pairing.

[0044] Figure 6 A schematic diagram of a flow chart of a WiFi remote controller pairing method provided by another embodiment of the present invention is shown in FIG. Figure 6 As shown, in this embodiment, the method includes steps S110-S160. That is, in this embodiment, after step S140 of the above embodiment, the method further includes steps S150 and S160.

[0045] S150: After pairing is completed, the WiFi remote controller sends pairing confirmation information to the target home appliance, and receives pairing completion information returned by the target home appliance for two-way confirmation;

[0046] S160: After the WiFi remote controller displays the pairing success information, it sends a control signal to the target home appliance to control the target home appliance.

[0047] In an embodiment of the present invention, after pairing is completed, the WiFi remote controller sends pairing confirmation information to the target home appliance, wherein the pairing confirmation information may be a verification code information or a confirmation instruction information triggered by a confirmation button. After receiving the pairing confirmation information, the home appliance will send pairing completion information to the WiFi remote controller, and the WiFi remote controller receives the pairing completion information returned by the target home appliance for two-way confirmation. It can be understood that the accuracy and security of the pairing can be ensured by further two-way pairing confirmation. After the pairing two-way confirmation is passed, the WiFi remote controller establishes a communication connection with the target home appliance, and the pairing success information will be displayed on the WiFi remote controller. The user can control or monitor the status of the target home appliance through the WiFi remote controller. It should be noted that in this embodiment, in addition to displaying the pairing information, the feedback RSSI value, that is, the signal strength, can also be displayed on the display interface of the WiFi remote controller.

[0048] In summary, in this embodiment, the implementation of the WiFi remote control pairing method has the following advantages: 1. Improving pairing accuracy: By presetting the home appliance RSSI threshold range and the dynamic home appliance RSSI threshold range, it can ensure that only home appliances with signal strength within a reasonable range are paired with the WiFi remote control, effectively avoiding the occurrence of mispairing, making the pairing process more stable and reliable, and improving the pairing accuracy and pairing success rate; 2. Reducing mispairing: By presetting the remote control RSSI threshold range and the dynamic remote control RSSI threshold range, the pairing feedback signal is filtered, and only the signal with RSSI value within the set threshold range is processed, thereby reducing the interference of long-distance devices, reducing the probability of mispairing, and further improving the pairing accuracy and pairing success rate; 3. Simplifying user operations: Adding a user interface prompt function, displaying the pairing status and signal strength in real time, so that the user can intuitively understand the pairing progress and possible problems, simplifying the operation steps in the pairing process, and improving the user experience; 4. Enhancing pairing security: By adding a pairing two-way confirmation mechanism, it is ensured that only legitimate devices can be successfully paired, and the security of the pairing process is enhanced.
