Detailed Implementation

[0019] The technical solutions of the embodiments 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, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0020] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or server that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0021] Please see Figure 1 , Figure 1 This is a schematic diagram of an application environment provided in an embodiment of this application, including a water dispenser 101 and a WiFi router 102.

[0022] In one possible embodiment, a WiFi router 102 is installed inside the house to transmit wireless signals, and a water dispenser 101 is also installed inside the house to receive wireless signals. The water dispenser 101 and the WiFi router 102 are connected wirelessly, acting as a transmitter and receiver respectively. CSI (Channel State Information) is a set of key parameters describing the characteristics of a wireless channel in a wireless communication system. It is mainly used to characterize the channel characteristics (such as fading, multipath effects, and interference) during signal transmission between the transmitter and receiver. Specifically, channel state information typically includes information such as channel amplitude, phase, multipath delay, and angle. Therefore, the water dispenser 101 can obtain the current channel state information of the wireless signal during transmission.

[0023] In this embodiment, the water dispenser 101 includes a main control board 111 and a heating module 121. The main control board 111 acquires current channel state information; the current channel state information reflects the wireless signal characteristics within the current building; the current channel state information is analyzed to obtain the current activity status of people within the building; if the current activity status matches a preset trigger condition, a control strategy corresponding to the preset trigger condition is acquired; and the water dispenser is heated based on the control strategy corresponding to the preset trigger condition. The heating module 121 is used to heat water at a set time and temperature according to the control strategy.

[0024] In this embodiment of the application, by analyzing the current channel state information in the current house, the current activity status of the people in the house is obtained. Different control strategies are set according to different current activity statuses of the people, so as to avoid the energy waste of "all on / all off" control of the water dispenser, and at the same time reduce the hardware working time of the water dispenser and improve the hardware life.

[0025] The following describes a specific embodiment of a water dispenser control method based on personnel identification, according to this application. Figure 2 This is a flowchart illustrating a water dispenser control method based on personnel identification provided in an embodiment of this application. Figure 1 This specification provides method operation steps as shown in the embodiments or flowcharts, but based on conventional or non-inventive labor, more or fewer operation steps may be included. The order of steps listed in the embodiments is merely one possible execution order among many and does not represent the only execution order. In actual system or server products, the methods shown in the embodiments or drawings can be executed sequentially or in parallel (e.g., in a parallel processor or multi-threaded processing environment). Specifically, as shown in the embodiments or drawings... Figure 2 As shown, it may include: S201: Obtain current channel state information; the current channel state information is used to reflect the characteristics of the wireless signal in the current building.

[0026] S202: Analyze the current channel state information to obtain the current activity status of people inside the building.

[0027] S203: If the current personnel activity status matches the preset trigger condition, obtain the control strategy corresponding to the preset trigger condition.

[0028] S204: Control the water dispenser heating based on the control strategy corresponding to the preset trigger conditions.

[0029] Figure 3 This is a flowchart illustrating a water dispenser control method based on personnel identification provided in an embodiment of this application. Figure 2 The method may include: S301: Obtain current channel status information.

[0030] In this embodiment, the current channel state information is used to reflect the characteristics of the wireless signal within the building. Channel state information is a set of channel characteristics measured by the receiver through pilot signals in wireless communication. Essentially, it contains key information such as amplitude attenuation, phase shift, multipath delay, and angle spread of the signal during transmission in the transmitter-channel-receiver link. Since people inside the building are dynamic scatterers, their movement alters the propagation path of the wireless signal, thus affecting the signal's amplitude, phase, angle, and other information.

[0031] S302: Perform preprocessing operations on the current channel state information to obtain preprocessed channel state information.

[0032] Before analyzing the current channel state information to obtain the current activity status of people inside the building, it is necessary to preprocess the current channel state information to conduct personnel activity analysis more quickly and accurately.

[0033] In one possible embodiment, the current channel state information is preprocessed to obtain preprocessed channel state information, including: S312: Perform hardware nonlinear error elimination and linear interval compensation on the current channel state information to obtain the channel state information after data calibration.

[0034] During signal transmission and reception, the physical characteristics of the devices can cause the measured values ​​of channel state information to deviate from the true channel state, resulting in hardware nonlinear errors. Therefore, it is necessary to eliminate the hardware nonlinear errors of the current channel state information.

[0035] In one possible embodiment, a mapping relationship between hardware error and channel state information measurement value can be established using a known reference signal. The current hardware error can be obtained using the current measurement value, and then the current hardware error can be corrected and eliminated to achieve hardware nonlinear error elimination.

[0036] In one possible embodiment, linear interval compensation can also be performed by utilizing the phase correlation between Received Signal Strength (RSS) and channel state information. Phase distortion caused by hardware nonlinearity can be compensated through phase correlation.

[0037] S322: Use a sliding window to detect abrupt changes in the channel state information after data calibration, and replace the outliers at the abrupt changes with the local median to obtain the channel state information after outlier processing.

[0038] In one possible embodiment, the channel state information may have abrupt changes due to transient interference (such as device startup), device noise, or other interference such as intense human activity. Therefore, a sliding window can be used to detect these abrupt changes.

[0039] A sliding window is a local statistical method that analyzes the statistical characteristics of data within a window to determine if there are any abrupt changes. The specific steps include: setting the window width to 20 sampling points; sliding the window along the time axis in steps of one sampling point; calculating the mean and standard deviation of the CSI amplitude or phase data within the window; and identifying any data point whose deviation from the mean exceeds a threshold.

[0040] The local median is the median of all data within a window except for outliers. By replacing outliers with the local median, we obtain channel state information after outlier processing, which can maintain the continuity and accuracy of the data.

[0041] S332: Perform Gaussian filtering on the channel state information after outlier processing to obtain preprocessed channel state information.

[0042] In this embodiment, Gaussian filtering is a linear smoothing filter that specifically eliminates noise by replacing the value of each data point with the weighted average of the values ​​of its neighboring data points.

[0043] The above steps preprocess the current channel state information to facilitate accurate analysis of the current personnel activity status.

[0044] S303: Perform principal component analysis on the preprocessed channel state information to obtain at least one principal component feature.

[0045] In one possible embodiment, the contribution rate of the principal component features is greater than a preset contribution rate threshold. In this embodiment, principal component analysis is performed on the preprocessed channel state information, and features with a contribution rate greater than 85% are retained as principal component features. Finally, the CSI data of 30 subcarriers is reduced to 3 principal components, which reduces the difficulty of subsequent calculations.

[0046] S304: Extract time-domain statistical features from at least one principal component feature to obtain time-domain statistical features.

[0047] In one possible embodiment, the time-domain statistical features include at least one of the mean feature, variance feature, or peak feature.

[0048] S305: Determine the current activity status of personnel based on time-domain statistical characteristics.

[0049] Since human activities can affect channel state information, the fluctuation of channel state information can be obtained by analyzing time-domain statistical characteristics, thereby determining whether there are people currently active inside the house.

[0050] In one possible embodiment, determining the current activity status of personnel based on time-domain statistical characteristics includes: Optionally, if the time-domain statistical characteristics are greater than a preset characteristic threshold, the movement state is determined as the current activity state of the personnel.

[0051] In this embodiment of the application, the movement status represents the presence of active personnel in the current building; Optionally, if the time-domain statistical characteristics are less than or equal to a preset characteristic threshold, the static state is determined as the current activity state of the personnel.

[0052] In this embodiment of the application, the static state indicates that there are currently no active persons in the house.

[0053] For example, taking the mean characteristic as an example, the mean characteristic threshold can be determined through a large amount of test data. If the mean characteristic of the current channel state information is greater than the mean characteristic threshold, it indicates that the current signal fluctuation is large and there are people active in the house. If the mean characteristic of the current channel state information is less than or equal to the mean characteristic threshold, it indicates that the current signal fluctuation is small and there are no people active in the house.

[0054] S306: If the current personnel activity status matches the preset trigger condition, obtain the control strategy corresponding to the preset trigger condition.

[0055] In one possible embodiment, the current activity status of people has different levels, each representing a different level of activity of people in the house.

[0056] For example, the current activity level of people can be categorized into three levels, from highest to lowest: Level 1, Level 2, and Level 3. Level 1 activity indicates that people are actively moving around in the house, so the probability of using hot water is relatively high, and the corresponding control strategy can be continuous heating. Level 2 activity indicates that people are occasionally moving around in the house, so the probability of using hot water is relatively low, and the corresponding control strategy can be heating at intervals. Level 3 activity indicates that there is no activity in the house or that people are inactive for a long time (at night), so the probability of using hot water is extremely low, and the corresponding control strategy can be continuous sterilization without heating.

[0057] S307: Controls the water dispenser heating based on the control strategy corresponding to the preset trigger conditions.

[0058] In this application, the current channel status information in the current house is analyzed to obtain the current activity status of the people in the house. Different control strategies are set according to different current activity statuses of the people, so as to avoid the energy waste of "all on / all off" control of the water dispenser, and at the same time reduce the hardware working time of the water dispenser and extend the hardware life.

[0059] Figure 4 This is a flowchart illustrating a method for obtaining a control strategy provided in an embodiment of this application. Figure 1 If the current personnel activity status matches the preset trigger conditions, obtain the control strategy corresponding to the preset trigger conditions, including: S401: If the current personnel activity status includes the movement status, determine that the current personnel activity status matches the first preset condition.

[0060] In this embodiment of the application, the preset triggering condition includes a first preset condition, which can be the detection of dynamic movement of a person.

[0061] S402: Obtain the first heating strategy corresponding to the first preset condition.

[0062] In this embodiment, the first heating strategy is used to instruct the water dispenser to continuously heat and maintain the water temperature at a first preset temperature. Specifically, the first heating strategy can be based on a proportional-integral-derivative (PID) controller algorithm to control the water temperature to maintain 98℃±2℃.

[0064] In this embodiment of the application, the preset triggering condition also includes a second preset condition, which can be that the person remains still for more than or equal to 10 minutes.

[0065] S502: Obtain the second heating strategy corresponding to the second preset condition; In this embodiment, the second heating strategy instructs the water dispenser to decrease the preset temperature at preset intervals and maintain the water temperature at a second preset temperature, wherein the second preset temperature is lower than the first preset temperature. Specifically, the second heating strategy may involve decreasing the temperature by 10°C every 5 minutes, down to a minimum of 60°C, and maintaining the temperature at 60°C.

[0067] In this embodiment, the preset triggering condition further includes a third preset condition, wherein the second time threshold is greater than the first time threshold. The third preset condition can be a continuous static state greater than or equal to 30 minutes.

[0068] S602: Obtain the third heating strategy corresponding to the third preset condition.

[0069] In this embodiment, the third heating strategy is used to instruct the water dispenser to maintain the water temperature at a third preset temperature, which is lower than the second preset temperature. The third heating strategy can be to maintain the water temperature at 45°C, which is sufficient to meet basic sterilization requirements.
