Description

Technical Field

[0001] This application relates to the field of smart home technology, and more specifically, to a method for adjusting operating power and a storage medium. Background Technology

[0002] Against the backdrop of ever-increasing global energy demand, escalating resource scarcity, and growing calls for environmental protection, the development of energy efficiency management and energy-saving control technologies for water heaters, as an indispensable high-energy-consuming appliance in modern households, is particularly important. Water heaters account for a significant proportion of energy consumption in daily household water supply, especially in the frequent and energy-intensive activity of bathing. Therefore, efficient and precise energy-saving control strategies are of great significance for reducing household energy consumption, improving energy utilization efficiency, and mitigating environmental burden.

[0003] Currently, energy-saving control solutions for water heaters on the market mainly rely on timer control. Timer control achieves energy savings by allowing users to preset the start and stop times of the water heater. However, this control method has inherent limitations, namely a lack of flexibility in responding to actual showering needs. Since users' showering habits may fluctuate due to various factors (such as work, social activities, and seasonal changes), the preset time may not accurately match the user's actual water demand. For example, when a user showers earlier or later than expected, the water heater may either start heating prematurely, resulting in energy waste, or fail to heat the water in time, thus affecting the user experience. Especially when the water temperature is insufficient, additional energy consumption may be required to reach the user's desired water temperature.

[0004] No effective solution has yet been proposed to address the problem that related technologies cannot flexibly respond to the actual bathing process. Summary of the Invention

[0011] In an exemplary embodiment, adjusting the first operating power based on environmental information of the target area to determine the target operating power includes: determining whether the sub-environmental information conforms to corresponding preset environmental information when the environmental information includes multiple sub-environmental information; determining an adjustment factor for the sub-environmental information that does not conform to the corresponding preset environmental information; and adjusting the first operating power according to the adjustment factor to determine the target operating power.

[0027] According to one aspect of the embodiments of this application, a method for adjusting operating power is provided. This method for adjusting operating power is widely applicable to whole-house intelligent digital control application scenarios such as smart homes, smart home ecosystems, and intelligence house ecosystems. Optionally, in this embodiment, the above-mentioned method for adjusting operating power can be applied to, for example... Figure 1 The hardware environment shown consists of terminal device 102 and server 104. For example... Figure 1 As shown, server 104 is connected to terminal device 102 via a network and can be used to provide services (such as application services) to the terminal or clients installed on the terminal.

Cloud computing and / or edge computing services can be configured on the server or independently of the server to provide data processing services for server 104.

[0028] The aforementioned network may include, but is not limited to, at least one of the following: wired network, wireless network. The aforementioned wired network may include, but is not limited to, at least one of the following: wide area network, metropolitan area network, local area network. The aforementioned wireless network may include, but is not limited to, at least one of the following: Wi-Fi (Wireless Fidelity), Bluetooth.

[0029] This embodiment provides a method for adjusting operating power, applied to the aforementioned terminal device. Figure 2 This is a flowchart of a method for adjusting operating power according to an embodiment of this application, the process including the following steps:

[0030] Step S202: Obtain audio data of the target area and determine the water usage event corresponding to the audio data through a classification model;

[0031] Audio data from the environment is collected in real time by audio sensors (such as microphones) placed in a target area (such as a bathroom). The audio data is then fed into a pre-trained classification model, which can identify and determine the type of water use event corresponding to the data.

[0032] Step S204: Determine the preset duration corresponding to the water usage event, and determine the action state of the target object based on the preset duration, wherein the target object is located in the target area;

[0033] Optionally, the historical water usage events previously output by the classification model are obtained, and it is determined whether the water usage event and the historical water usage events are consistent; if the water usage event and the historical water usage events are inconsistent, a preset duration corresponding to the water usage event is determined.

[0034] The currently identified water usage event is compared with the historical water usage events previously output by the classification model to determine if the current water usage event is consistent with the historical water usage event. If the water usage event type changes, it indicates that the user's behavior pattern has changed.

[0035] When a water usage event is found to be inconsistent with historical water usage events, the current action state of the target object is determined based on the preset duration standard of water usage events and the duration of the current water usage event. For example, when the transition from the sound event of turning on the tap to the sound event of turning off the tap is detected, it can be inferred that the user has entered the paused shower stage from the preparation stage.

[0036] Step S206: Determine the target operating power of the target device based on the action state of the target object, and adjust the actual operating power of the target device to the target operating power, wherein the target device is located in the target area.

[0037] Based on the assessment of the target object's operational status, the target operating power of the target equipment is further determined, thus avoiding energy waste by matching the user's actual needs. For example, when the user is taking a shower, the system may maintain or increase the water heater's heating power to ensure a stable water temperature; while when the user pauses showering (such as applying shower gel or scrubbing), the heating will be reduced or stopped to achieve energy savings.

[0038] Through the above steps, by analyzing audio data from the target area, water usage events are intelligently identified, thereby dynamically adjusting the water heater's operating status to achieve high efficiency and energy saving. First, audio data is collected, and a classification model is used to identify the type of current water usage event. Based on preset duration standards, the user's action status is intelligently determined, such as preparing to shower, pausing shower, or finishing shower. Finally, based on the user's action status, the target operating power of the water heater is optimized and adjusted to ensure that comfortable water usage needs are met while minimizing energy waste, thus solving the problem of not being able to flexibly respond to actual showering processes.

[0039] Optionally, determining a preset duration corresponding to the water usage event and determining the action state of the target object based on the preset duration includes: if the water usage event is a first water usage event, determining the preset duration corresponding to the first water usage event as a first preset duration; determining whether a second water usage event is identified within the first preset duration; if no second water usage event is identified within the first preset duration, determining the action state of the target object as a first action state; and if a second water usage event is identified within the first preset duration, determining the action state of the target object as a second action state.

[0040] Water usage incidents include: turning on the tap, using the shower, and turning off the tap.

[0041] Action states include: waiting to shower (awaiting shower state), showering, temporarily stopping showering (such as applying shower gel / scrubbing, i.e., pausing shower state), or showering completed (ending shower state).

[0042] Upon detecting a first water usage event (e.g., a user turning on the tap and adjusting the water temperature), a timer for a first preset duration (assumed to be 3-10 seconds) is immediately initiated. During this first preset duration, subsequent acoustic signals are monitored to determine if a second water usage event different from the first (e.g., the sound of water flowing from a showerhead) is detected. If no second water usage event is detected within the first preset duration, it means the user's action did not follow the expected pattern. In this case, the water heater's operating parameters will not be changed to prevent insufficient hot water supply or overheating due to misoperation.

[0043] Conversely, if a second water usage event (e.g., showerhead water flow) is successfully identified within the first preset duration, indicating that the user's behavior matches the expected pattern, it can be further determined that the user has transitioned from the preparation phase to the showering state or another specific state (e.g., the shower is paused). Subsequently, based on the determined user action state, the water heater adopts a matching energy-saving control strategy, such as increasing or decreasing the heating power, to maintain a suitable water temperature and avoid energy waste.

[0044] Optionally, determining a preset duration corresponding to the water usage event and determining the action state of the target object based on the preset duration includes: if the water usage event is a third water usage event, determining the preset duration corresponding to the third water usage event as a second preset duration; if the duration of the third water usage event is greater than the second preset duration, determining the action state of the target object as a third action state; and if the duration is less than or equal to the second preset duration, determining the action state of the target object as a second action state.

[0045] For a detected third water usage event (water usage pause event), if the duration of the third water usage event is greater than the second preset duration, the target object's action state is determined to be the third action state (paused shower state). If the duration of the third water usage event is less than or equal to the second preset duration, the system determines the target object's action state to be the second action state (showering state).

[0046] Optionally, determining a preset duration corresponding to the water usage event and determining the action state of the target object based on the preset duration includes: if the water usage event is a fourth water usage event, determining the preset duration corresponding to the fourth water usage event as a third preset duration; determining whether other water usage events are identified within the third preset duration; if other water usage events are identified within the third preset duration, determining the action state of the target object as a third action state; and if no other water usage events are identified within the third preset duration, determining the action state of the target object as a fourth action state.

[0047] For the identified fourth water use event (faucet turning off event), within the "third preset duration", acoustic signals continue to be collected to assess whether other water use events different from the "fourth water use event" are identified, such as the transition from "showering" state to "spraying bath liquid / rubbing" state.

[0048] If other water usage events are detected within the "third preset duration", the user's action state will be determined as the "third action state" (such as the paused shower state). If no other water usage events are detected within the "third preset duration", the action state will be determined as the "fourth action state" (i.e. the shower ended state).

[0049] Optionally, determining the target operating power of the target device based on the action state of the target object includes: when the action state of the target object is a first action state, determining a first operating power corresponding to the first action state, and adjusting the first operating power according to the environmental information of the target area to determine the target operating power; when the action state of the target object is a second action state and the temperature of the target device is lower than a first preset temperature, determining a second operating power corresponding to the second action state, and adjusting the second operating power according to the environmental information of the target area to determine the target operating power; when the action state of the target object is a third action state and the temperature of the target device is lower than a second preset temperature, determining a third operating power corresponding to the second action state, and adjusting the third operating power according to the environmental information of the target area to determine the target operating power, wherein the first operating power is greater than the second operating power, and the second operating power is greater than the third operating power.

[0050] The first operating state can be understood as the waiting state for showering. At this time, a higher operating power (first operating power) is determined based on environmental information (such as water temperature, external temperature, etc.) to ensure that the water temperature quickly reaches or is maintained within the user-set comfort range.

[0051] The second operating state can be understood as the showering state. If the current temperature of the target device (water heater) is lower than a preset relatively high temperature (first preset temperature), the operating power is adjusted to an intermediate level (second operating power). This can both prevent the water temperature from dropping too quickly and significantly reduce energy consumption, avoiding unnecessary heating.

[0052] The third operating state can be understood as the shower pause state. If the water temperature of the water heater is lower than a lower preset temperature (second preset temperature) at this time, the operating power will be further reduced to a minimum level (third operating power) to maintain only the necessary heat preservation effect, greatly reducing energy waste during non-shower periods.

[0053] After determining the operating power for each action state, the operating power is further fine-tuned based on the environmental information of the target area (such as indoor and outdoor temperature, humidity, etc.).

[0054] Through the embodiments of this application, the operation of the water heater is not only based on user actions, but also takes into account the influence of the external environment on the water temperature, thereby ensuring that the water heater can efficiently maintain the water temperature under different environmental conditions and avoid excessive or insufficient energy consumption.

[0055] Optionally, adjusting the first operating power based on the environmental information of the target area to determine the target operating power includes: when the environmental information includes multiple sub-environmental information, determining whether the sub-environmental information conforms to the corresponding preset environmental information; determining an adjustment factor for the sub-environmental information that does not conform to the corresponding preset environmental information; and adjusting the first operating power according to the adjustment factor to determine the target operating power.

[0056] Environmental information includes multiple dimensions of sub-environmental information, including but not limited to temperature, humidity, light intensity, CO2 concentration, and human activity status. Preset environmental information refers to standard conditions set based on the environmental requirements for normal and efficient operation of appliances or user preferences. For example, for water heaters, preset environmental information includes a suitable ambient temperature range (e.g., 20-25℃) to ensure that the water heater operates under relatively ideal conditions, avoiding increased energy consumption due to overheating or frequent activation of the heating system due to excessive cold.

[0057] When the sub-environment information does not match the preset environment information, an "adjustment factor" is calculated. The adjustment factor is calculated based on the difference between the sub-environment information and the preset environment information. For example, if the temperature of the target area is much higher than the preset temperature range, the heating demand of the water heater is reduced, and the operating power can be reduced based on the adjustment factor; conversely, if the temperature of the target area is lower than the preset range, the water heater may need to be started more frequently to maintain the water temperature, and the operating power can be increased based on the adjustment factor.

[0058] For example, for the sub-environmental information of temperature, the adjustment factor might be calculated based on the following formula:

[0059] Adjustment factor = 1 - {(current temperature - preset temperature) / preset temperature}. The smaller the difference between the current temperature and the preset temperature, the closer the adjustment factor is to 1, indicating that the environmental conditions are closer to the preset standard, and the appliance can operate at a power level close to its first operating power. Conversely, the smaller the adjustment factor, the more the environmental conditions deviate from the standard, and the appliance's operating power needs to be increased or decreased accordingly to adapt to environmental changes.

[0060] Optionally, determining the water use event corresponding to the audio data through a classification model includes: denoising the audio data using a target denoising algorithm to determine the denoised audio data; segmenting the denoised audio data and normalizing each segmented data segment; extracting the acoustic feature vector of each normalized data segment and inputting the acoustic feature vector of each data segment into the classification model, so that the classification model determines the water use event corresponding to the audio data based on the acoustic feature vector of each data segment.

[0061] It should be noted that the bathroom environment is complex, with various background noises such as water flow, ventilation, and external ambient noise, which can interfere with the identification of acoustic events. Targeted denoising algorithms (such as wavelet thresholding, spectral subtraction, or deep learning denoising models) remove irrelevant noise components from the collected raw audio data, retaining sound signals related to bathing and improving the accuracy of subsequent acoustic event classification.

[0062] Continuous audio signals are segmented into a series of shorter data segments. Segmentation helps convert audio signals into a format that classification models can process. At the same time, by controlling the length of the data segments (e.g., 50ms), a balance can be struck between real-time performance and recognition accuracy, ensuring that the model can respond promptly to changes in sound events while avoiding the inability to capture complete event features due to segments that are too short.

[0063] Normalization is used to adjust the amplitude range of data segments, ensuring that audio data collected from different devices or environments are comparable when input into the model. By normalizing the signal amplitude to the [0,1] interval, model misjudgment caused by differences in signal strength can be avoided.

[0064] Features such as Mel frequency cepstral coefficients (MFCC), time-domain peak values, and frequency spectral entropy can effectively describe the time-frequency characteristics of sound signals.

[0065] The classification model, built on deep learning techniques (such as Convolutional Neural Networks (CNN), Long Short-Term Memory Networks (LSTM), etc.), can learn the distinguishing patterns of different acoustic events from acoustic feature vectors. Through training, the model can accurately identify the acoustic features of water usage stages such as "turning on the tap", "shower water", and "turning off the tap".

[0066] Optionally, determining the preset duration corresponding to the water use event includes: acquiring historical water use data of the target object, and determining the interval duration of each water use event switching in the historical water use data; determining the preset duration corresponding to the water use event based on the interval duration of the water use event switching.

[0067] The system collects water usage records from the target user over a period of time, including the time when the tap is turned on and off, water temperature adjustments, and water flow. Through big data analysis, it extracts key information about the user's water usage patterns, including frequency, duration, and preferences. Furthermore, it obtains the interval between consecutive water usage events, i.e., the time difference between the end of one water usage event and the start of the next. By analyzing these intervals, it learns the user's habit transition time between different water usage behaviors.

[0068] Based on the analysis of the interval between water usage events, a reasonable preset duration is set for each water usage event. For example, if data analysis shows that users usually adjust the water temperature for about 10 seconds before taking a shower, then the preset duration of the water usage event "adjusting the water temperature" will be set to about 10 seconds.

[0069] To better understand the process of the above-mentioned method for adjusting operating power, the implementation flow of the above-mentioned method for adjusting operating power will be described below in conjunction with optional embodiments, but this is not intended to limit the technical solution of the embodiments of this application.

[0070] This embodiment provides a method for adjusting operating power. Figure 3 This is a schematic diagram of a method for adjusting operating power according to an embodiment of this application, as shown below. Figure 3 As shown, the specific steps are as follows:

[0071] Step S301: Acoustic signal acquisition and preprocessing.

[0072] Acoustic sensors were deployed in the bathing area to collect acoustic signals from the environment. Wavelet threshold denoising technology was used to denoise the original acoustic signals, eliminating noise from non-target sound sources. The denoised acoustic signals were then segmented into fixed-length segments, and amplitude normalization was performed to ensure that each signal segment was within the [0,1] interval. Acoustic feature vectors were extracted from the normalized signals using Mel-frequency cepstral coefficients, time-domain peak values, and frequency spectral entropy as key indicators.

[0073] Step S302: Input the preprocessed acoustic signal into the trained acoustic event recognition model and output the corresponding acoustic event type. The acoustic event type includes faucet turning on event, shower water output event, faucet turning off event, and water usage interruption event.

[0074] The extracted acoustic feature vectors are fed into a pre-trained acoustic event recognition model, which is based on a hybrid architecture of convolutional neural networks and long short-term memory networks.

[0075] The model outputs types of acoustic events, including but not limited to "tap turning on event", "shower water output event", "tap turning off event" and "water usage pause event", in order to identify different stages of the user's shower process.

[0076] Step S303: Based on the identified acoustic event type and event duration, determine the user's current bathing state, which includes the state of waiting to bathe, bathing in progress, bathing paused, and bathing ended.

[0077] Based on the combination of acoustic event type and duration, the state changes of the user's bathing activity are determined. Specifically:

[0078] When the system detects a "faucet turning on event" and then detects a "showerhead water output event" 3 to 10 seconds later, it determines that the user has moved from the preparation stage to the "showering state".

[0079] If a "water use pause event" is detected while "showering" and the duration exceeds 15 seconds, the showering status will automatically be adjusted to "shower paused".

[0080] When the "paused shower state" encounters the "showerhead water event" again, it indicates that the user has resumed showering, and the state returns to "showering state".

[0081] If a "faucet-off event" is detected in the "showering" or "paused showering" state and lasts for more than 30 seconds, and no other water-related events are detected subsequently, then the "showering state ends" is determined.

[0082] Step S304: Based on the user's current bathing status, send the corresponding control command to the water heater controller to adjust the water heater's heating power or start / stop status, thereby achieving real-time energy-saving control.

[0083] Ready to shower: When the system determines that the user is about to start showering, it instructs the water heater to operate at 80%-90% of its rated power to preheat quickly and ensure that the water temperature can rise to the user's preset comfort level within 30 seconds.

[0084] During shower: Real-time monitoring of water temperature. When the water temperature drops below the preset lower limit (e.g., 40℃), the water heater will supplement heating with 50%-60% of its rated power to ensure that the water temperature remains stable within the preset temperature range (e.g., 42℃).

[0085] Pause Shower Mode: The heating process is stopped immediately, and the water heater's heat preservation mode is activated simultaneously. The water temperature is maintained by the device's excellent heat preservation performance. Only when the water temperature drops below the heat preservation threshold (such as 35℃) will a small amount of heating be performed at a lower power (20%-30%).

[0086] Step S305: Continuously collect acoustic signals and repeat steps S302-S304 until the shower state is detected and maintained for a preset time, then control the water heater to enter standby state.

[0087] Through the above description of the embodiments, those skilled in the art can clearly understand that the methods according to the above embodiments can be implemented by means of software plus necessary general-purpose hardware platforms. Of course, they can also be implemented by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of this application, in essence, or the part that contributes to the prior art, can be embodied in the form of a software product. This computer software product is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk) and includes several instructions to cause a terminal device (which may be a mobile phone, computer, server, or network device, etc.) to execute the methods of the various embodiments of this application.
