The application scenarios of the embodiments of the present invention are explained below:

FIG. 1 is an application scenario diagram of the water heater preheating control method provided by the embodiment of the present invention. The water heater preheating control method provided by the embodiment of the present invention can be used in a smart home application scenario, and the execution of the method provided by this embodiment is performed. The main body may be a smart water heater or a cloud server connected to the smart water heater. In this embodiment, the cloud server is used as the execution body for description. More specifically, as shown in FIG. 1 , the cloud server 11 can be connected to the smart water heater 12 respectively. communicate with the terminal device 13, wherein the terminal device 13 is a wearable device such as a smart watch, a smart bracelet, etc., the terminal device 13 can collect the physiological indicators of the user to generate body state data, and send the body state data to the cloud server 11, The cloud server 11 receives the body state data sent by the terminal device 13, and performs pre-heating control on the smart water heater 12 based on the body state data, so as to realize the water temperature control of the smart water heater 12, so that the timing of the smart water heater 12 heating the water temperature and the waking time of the user match.

In the prior art, the heating control of the water storage type water heater, the traditional water temperature heating control, is based on a temperature sensor. The water temperature of the water tank will always decrease with the heat dissipation. Therefore, this method will cause higher power consumption and increase the user's use cost. Smart water heaters in other related technologies are based on task planning and set by the user to heat the water temperature at a fixed time. However, the current user’s daily sleep time and wake-up time are not fixed. The hot water is not heated to the ideal temperature, which affects the comfort of water; or it is heated too early, causing the problem of increased energy consumption.

The reason for the above problem is that the storage water heater needs to be pre-heated to ensure that the temperature of the water tank reaches the ideal temperature for use. However, when the user is in a sleep state, it is impossible to accurately judge the time when the user wakes up, and thus cannot judge the user's water use time. There is also no way to control the water heater to preheat in advance at the exact time. Therefore, there is an urgent need for a control method capable of accurately judging the wake-up time of the user and preheating in advance based on the wake-up time, so as to realize the preheating control of the intelligent water heater.

The technical solutions of the present invention and how the technical solutions of the present invention solve the above-mentioned technical problems will be described in detail below with specific examples. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 2 is a flowchart of a water heater preheating control method provided by an embodiment of the present invention, which is applied to a cloud server. As shown in FIG. 2 , the water heater preheating control method provided by this embodiment includes the following steps:

Step S101: Receive body state data sent by the terminal device, where the body state data is used to represent the current physiological index of the user.

Exemplarily, the terminal device is, for example, a wearable device such as a smart watch and a smart bracelet. By contacting the user's body surface, the user's physiological indicators, such as body temperature, heartbeat, and blood pressure, can be measured. The terminal device is connected to the cloud server for communication, and can send data to and from the cloud server. More specifically, there are many ways for the terminal device to communicate with the cloud server. The terminal device can directly access the Internet and communicate with the cloud server, or it can be The terminal device is connected to the Internet through other relay network devices, so as to communicate with the cloud server, which will not be described in detail this time.

Further, when the cloud server receives the physical state data uploaded by the terminal device, it can receive the physical state data for a period of time at one time, so as to know the physiological indicators of the user in the current and previous period of time, or it can be based on preset time intervals. , to obtain the current body state data, so as to obtain the physiological index of the user at the current moment.

Step S102: Determine the wake-up time of the user according to the body state data.

Exemplarily, after the cloud server obtains the body state data and analyzes the body state data, the current state of the user may be determined, and more specifically, the current sleep stage of the user may be determined, for example, just falling asleep or nearly awake. The sleep stages are used to represent different time stages when the user is in a sleep state, and the sleep stages can be divided artificially according to time, or according to the physiological indicators of the user in different time periods. The time length of each sleep stage may be the same or different, which is not specifically limited this time.

Further, according to the preset historical sleep data, each sleep stage corresponds to a duration, and after the current sleep stage is determined, the duration corresponding to the current sleep stage can be determined, and then, according to the duration of the current sleep stage, and the current sleep stage The duration of the sleep stage after the sleep stage can determine the time between the current sleep stage and the user waking up, that is, the remaining sleep time, and then the user waking time can be determined according to the remaining sleep time.

Fig. 3 is a schematic diagram of a sleep stage provided by an embodiment of the present invention. As shown in Fig. 3, exemplarily, the body state data represents the user's body temperature. After the user enters the sleep state, the user's body temperature gradually decreases due to the decrease in body function and metabolism , and maintain it at a low level. With the gradual accumulation of sleep time, the user's physical function and metabolic capacity gradually recover, and the user's body temperature also gradually increases. According to the distribution of the user's body temperature in different time periods, it can be divided into three sleep stages, namely the first stage, the second node and the third stage shown in Figure 3. In the first stage, the user's body temperature is higher; In the second stage, the user's body temperature drops to a lower level, and in the third stage, the user's body temperature rises. Among them, the maintenance time of the first stage is a minutes, the maintenance time of the second stage is b minutes, and the maintenance time of the third stage is c minutes. The current sleep stage can be determined, and further, the duration of the stage after this stage can be determined as the remaining sleep duration. Further, according to the remaining sleep duration and the current system time, the wake-up time of the user can be determined.

Exemplarily, in this embodiment, the number of sleep stages can be set as required. The more the number of sleep stages, that is, the more detailed the division of sleep stages, the more accurate the wake-up time of the user. The larger the amount of data is, in a possible implementation, the number of sleep stages can be determined according to the type of smart water heater. For example, when the smart water heater is a zero-cold water heater equipped with a circulating pump, a larger number of Sleep stage to improve the water supply effect of the zero-cold water heater and reduce energy consumption.

Step S103 , based on the wake-up time of the user, control the smart water heater to preheat the water temperature, so that the water temperature of the smart water heater reaches a preset temperature at the wake-up time of the user.

Exemplarily, after the wake-up time of the user is determined, water temperature preheating may be performed according to the wake-up time of the user. In a possible implementation manner, the wake-up time of the user can be regarded as the water-use time, that is, when the system time reaches the wake-up time of the user, it is ensured that the water temperature in the water tank reaches the preset temperature, and then according to the wake-up time of the user and the preset temperature The mapping relationship between the heating power and the temperature rise rate, combined with the current water temperature and the preset temperature, determine the time to start the water temperature preheating, and control the water heater preheating time at the water temperature to heat with the corresponding heating power to It is realized that when the system time reaches the user's wake-up time, the temperature in the water tank can reach the preset temperature.

Wherein, optionally, if the intelligent water heater is a zero-cold water heater equipped with a circulating pump, after the intelligent water heater is controlled to preheat the water temperature so that the water temperature reaches the preset temperature, the circulating pump is controlled to start, and the hot water is pumped to the water outlet to achieve Zero cold water supply.

It should be noted that, in this embodiment, the cloud server is used as the execution subject to introduce the water heater preheating control method provided in this embodiment, wherein the cloud service can communicate with the smart water heater and the terminal device respectively. When the executive body of the water heater preheating control method provided in this embodiment is an intelligent water heater, the intelligent water heater can realize the preheating control method of the water heater without the need of a cloud server through communication with the terminal device, and achieve the The embodiment has the same technical effect and purpose, and its execution steps are different from the steps of the present embodiment, and the difference is only in the execution body. Therefore, for the embodiment with the intelligent water heater as the execution body, the description will not be repeated this time. Description of the steps in the examples.

In this embodiment, the body state data sent by the terminal device is received, and the body state data is used to represent the current physiological index of the user; according to the body state data, the wake-up time of the user is determined; based on the wake-up time of the user, the intelligent water heater is controlled to preheat the water temperature, In order to make the water temperature of the smart water heater reach the preset temperature when the user wakes up, the corresponding wake-up time of the user can be determined according to the body state data sent by the terminal device. The heating timing of the water heater matches the wake-up time of the user, which avoids the problem that the intelligent water heater cannot determine the user's water use time and heats up too early or too late, improving the comfort of water use and reducing energy consumption.

FIG. 4 is a flowchart of a water heater preheating control method provided by another embodiment of the present invention. As shown in FIG. 4 , the water heater preheating control method provided by this embodiment is the same as the water heater preheating control method provided by the embodiment shown in FIG. 2 . On the basis of , steps S102 and S103 are further refined, and the step of receiving the detection information sent by the terminal device is added, the water heater preheating control method provided by this embodiment includes the following steps:

Step S201: Receive detection information sent by a terminal device, where the detection information is used to determine whether the user is in a sleep state.

Step S202 , if it is determined according to the detection information that the user is in a sleep state, the body state data sent by the terminal device is received.

Exemplarily, taking the terminal device as a smart bracelet as an example, when the user wears the smart bracelet, the smart bracelet can capture the user's arm swinging motion according to the built-in gravity sensing unit, so as to generate a data for judging whether the user is in a sleep state. detection information. Because the step of collecting the user's physical state data usually takes a period of time. For example, to collect the user's heartbeat signal, the smart bracelet usually needs to continuously collect the vibration signal for more than 10 seconds to accurately determine the user's heartbeat frequency. The power consumption of the process is relatively large, which will increase the power consumption of the smart bracelet. In the process of generating detection information, the smart bracelet only needs to detect that the user's arm swings to determine that the user is in a non-sleep state. And for the application scenario of water heater preheating control, the real-time requirements are relatively low, and the detection information sent by the smart bracelet can be received at a long time interval, such as 10 minutes. Correspondingly, the smart bracelet can also be used for a long time. Generate and upload detection information at intervals. Therefore, the smart bracelet does not need to maintain a high sampling rate for signal sampling for a long time, which reduces the power consumption of terminal devices such as smart bracelets and improves battery life.

Further, if it is determined that the user is in a sleeping state according to the detection information, the process of receiving the physical state data sent by the terminal device, and the cloud server receiving the physical state data sent by the terminal device may be that the cloud server sends request information to the terminal device, and the terminal device sends the request information to the terminal device. After receiving the request information, the collection of physical state data is carried out. Therefore, if the cloud server determines that the user is not in a sleep state according to the detection information, it will not send the request information to the terminal device. The state data is collected to achieve the purpose of reducing power consumption.

Therefore, in this embodiment, the smart bracelet first detects whether the user is in a sleep state, generates detection information, and sends the detection information to the cloud server. The cloud server receives the detection information, and determines whether to receive the information sent by the terminal device according to the detection information. Body status data.

Step S203, acquiring the user identifier sent by the terminal device.

Step S204: Acquire corresponding historical sleep data according to the user identification, and the historical sleep data is used to represent the changes of the physiological indicators of the user over time when the user is in a sleep state.

Step S205 , according to the historical sleep data, determine multiple sleep stages of different users, and physiological indicators corresponding to each sleep stage, wherein, within the same sleep stage, the physiological indicators of the user have corresponding change rules.

Exemplarily, there is a binding relationship between the smart bracelet and the smart water heater, and the binding relationship can be implemented through a unified user identity. Specifically, for example, through another user terminal device, such as a smart phone, run a corresponding application to bind the smart bracelet and the smart water heater, the smart bracelet and the smart water heater correspond to the same user ID, and bind the smart bracelet to the smart water heater. Information is stored in cloud services. When the smart bracelet sends information to the cloud service, the user ID of the smart bracelet is uploaded synchronously, and the user of the smart bracelet can be determined through the user ID.

Exemplarily, according to the user identification, the corresponding historical sleep data is determined. The historical sleep data is generated before, and the user records the data of the changes of the user's physiological indicators over time when the user is in a sleep state. For example, the user's average sleep start time and end time, the user's average sleep duration, and the physiological indicators corresponding to multiple time points when the user is in a sleep state. Wherein, exemplarily, the historical sleep data may also include fields such as month, season, temperature, etc., which are used to represent the data of changes in physiological indicators over time when the user is in a sleep state under different months, seasons, temperatures and other conditions. I won't repeat them one by one.

Further, according to the historical sleep data, it is possible to determine multiple sleep stages when the user is in a sleep state, and physiological indicators corresponding to each sleep stage. Wherein, for different users (and user IDs), when they are in a sleep state, the number of sleep stages, and the start time, end time, and duration of each sleep stage may be different. That is, through the historical sleep data corresponding to the user identification, the personalized sleep data corresponding to the user wearing the smart bracelet can be determined, so that the user's wake-up time can be accurately determined, the accuracy of determining the user's wake-up time can be improved, and the user's wake-up time can be judged accurately. The wake-up time controls the accuracy of the water temperature preheating of the smart water heater and reduces the energy consumption of the smart water heater.

Step S206: Determine the sleep stage corresponding to the physical state data according to the multiple sleep stages determined by the historical sleep data.

Step S207: Determine the remaining sleep duration according to the sleep stage, and determine the wake-up time of the user according to the remaining sleep duration.

Exemplarily, according to the multiple sleep stages that can be determined according to the historical sleep data, each sleep stage corresponds to one or more sets of physical state data. More specifically, for example, according to the historical sleep data corresponding to the user identification, it is determined that the user has The sleep stages include sleep stage A, sleep stage B and sleep stage C, wherein, each sleep stage corresponds to different physiological indicators, taking sleep stage B as an example, the physiological index corresponding to sleep stage B is, the heartbeat frequency is 50 beats per second , the body temperature is 36 degrees Celsius. Further, according to the physiological index corresponding to the body state data, determine the sleep stage of the physiological index closest to the physiological index corresponding to the body state data in each sleep stage, and then determine the sleep stage according to the historical sleep data. The duration, and the sum of the durations of the sleep stages following this sleep stage (if any), is determined as the remaining sleep duration. Furthermore, according to the current system time and the remaining sleep duration, the wake-up time of the user can be determined.

In order to better introduce the process of determining the wake-up time of the user, a more specific embodiment will be described below. FIG. 5 is a schematic diagram of sleep stages corresponding to historical sleep data according to an embodiment of the present invention. As shown in FIG. 5 , the sleep stages corresponding to the historical sleep data include sleep stage A, sleep stage B, and sleep stage C, wherein , the duration of sleep stage A is 2 hours, the duration of sleep stage B is 4 hours, and the duration of sleep stage C is 2 hours. In sleep stage A, two detection time points (A1, A2) are included, and each detection time point corresponds to a set of data of heartbeat frequency and body temperature. The heart rate at time point A1 was 70, and the body temperature was 36.3 degrees Celsius; at time point A2, the heartbeat frequency was 65, and the body temperature was 36.1 degrees Celsius. In sleep stage B, including 4 detection time points (B1, B2, B3 and B4), the heartbeat frequency at time point B1 is 62, and the body temperature is 36 degrees Celsius; the heartbeat frequency at time point B2 is 60, and the body temperature is 35.6 degrees Celsius; The heartbeat frequency at time point B3 was 58 and the body temperature was 35.3 degrees Celsius; the heartbeat frequency at time point B4 was 52 and the body temperature was 35 degrees Celsius. In sleep stage C, two detection time points (C1 and C2) are included. The heartbeat frequency at time C1 is 60 and the body temperature is 35.5 degrees Celsius; the heartbeat frequency at time C2 is 65 and the body temperature is 36 degrees Celsius.

Further, according to the physical status data currently uploaded by the smart bracelet, the current physiological indicators of the user included in the physical status data include, for example, a heartbeat frequency of 60 and a body temperature of 35.5; and physiological indicators one hour ago, such as a heartbeat frequency of 35.5. 62. The body temperature is 36 degrees Celsius. According to the physiological indicators contained in the physical state data currently uploaded by the smart bracelet, and the physiological indicators of the sleep stage corresponding to the historical sleep data are compared, it is determined that the user's current sleep stage is sleep stage B. More specifically, the current sleep stage of the user is the time period from B1 to B2 in the sleep stage B, and further, according to the duration of the user's current sleep stage B (B1 to B2 time period), and the sleep stage C after the sleep stage B The duration of , can determine the remaining sleep time, and the user wake-up time.

Wherein, the data in the above embodiments are determined by historical sleep data, and are only exemplary, and the division of sleep stages can be freely set as required, which will not be repeated here.

In this embodiment, the sleep stage represented by the historical sleep data is compared with the body state data uploaded by the terminal device to determine the matching sleep stage, and then determine the user's wake-up time, so as to realize accurate sleep data based on the user's individualization. The prediction of user wake-up time improves the control accuracy of pre-heating control of smart water heaters.

Step S208: Determine the corresponding target heating temperature according to the user's body temperature.

Optionally, the body state data includes the user's body temperature, and after the user wakes up, there are differences in the user's body temperature for different users.
