In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a water temperature adjusting method according to an embodiment of the present application, including the following steps S1 to S4:
s1, acquiring first physiological state information of a first user before showering;
specifically, the first user may be any user, the first physiological state information before showering may be a period of time reserved for detecting the first physiological state information before showering after the user triggers the shower switch, and in this period of time, the shower device such as a water heater does not output water; in addition, the detection of the first physiological state information before showering can be directly carried out by triggering switches such as physiological state detection and the like;
s2, acquiring second physiological state information in the shower of the first user;
specifically, the second physiological state information in the shower is detected after water is discharged from a shower device such as a water heater, and whether water is discharged or not can be judged by detecting a water outlet valve of the water heater and the like;
s3, generating a corresponding adjusting strategy according to the first physiological state information and the second physiological state information;
generally, the first physiological state information and the second physiological state information can be obtained by detecting through a microwave radar; the principle of detecting the object by the microwave radar is mainly to emit electromagnetic waves to the object to be detected and then detect the signal intensity of echo signals, so that the signal intensity can be analyzed and converted into the position of the object in the space. When a person breathes, the fluctuation change of the chest of the body can cause the corresponding echo signal change, and then the received echo signal is processed, so that the information of the current respiratory frequency, the motion state of the human body and the like of the human body can be obtained;
in addition, since the first physiological state information is detected before showering, the first physiological state information can be used for representing the normal physiological state of the first user; and the second physiological state information is detected in the shower and can therefore be used to characterise the first user's response to the temperature of the shower water; finally, the influence of the shower water temperature on the first physiological state can be obtained according to the first physiological state information and the second physiological state information, and a corresponding adjusting strategy is generated according to the influence and is used for adjusting the outlet water temperature of the water heater;
s4, managing and controlling the water heater according to an adjusting strategy, and adjusting the water outlet temperature;
specifically, the adjustment strategy may be to adjust the outlet water temperature by adjusting the ratio of cold water to hot water, or the temperature of hot water; when the proportion of cold water and hot water is adjusted, the water outlet quantity of the cold water outlet pipe and the water outlet quantity of the hot water outlet pipe can be adjusted; the temperature of the hot water can be adjusted by heating the water temperature of the hot water storage tank and the like; the above methods are only two methods for adjusting the temperature of the outlet water, and are not specific limitations to the present embodiment.
As shown in fig. 2, in some embodiments, the water temperature adjustment method, as described above, precedes step s2. acquiring the second physiological state information in the first user's shower; further comprising the following steps S51 to S54:
s51, acquiring first corresponding relations between body type information and historical shower temperatures of all users; wherein the historical shower temperature is the last selected outlet water temperature when each user has a shower last time;
specifically, when the shower system adopting the method is applied to the environment such as a home or a hotel, a user often does not have only one person; due to individual differences, the body type information and the optimum temperature of each user are often different; the body type information can be obtained by detecting information of each angle or different postures of the user before showering; therefore, the last selected outlet water temperature of each user when the user has a shower last time is recorded and is bound with the body type information of each user, so that a first corresponding relation can be obtained, and the first corresponding relation can be stored in a local storage unit or a cloud database;
s52, acquiring first integral information of a first user;
that is, before the first user bathes, the identity information of the first user is not clear, and the identity of the first user can be determined by acquiring the body type information of the first user;
s53, determining a first historical shower temperature corresponding to the first user according to the first integral information and the first corresponding relation;
specifically, according to the first corresponding relation, the first integral information is matched in the first corresponding relation, and then a first historical shower temperature corresponding to the first user is determined, namely the shower temperature finally selected by the first user in the last shower is determined; if the corresponding historical shower temperature cannot be obtained through matching in the first corresponding relation according to the first integral information, water can be discharged according to the historical shower temperature or the average shower temperature corresponding to the body type information close to the first integral information, and the specific selection can be configured according to the actual situation, which is not limited specifically herein;
s54, controlling the water heater according to the first historical shower temperature, and enabling water to be discharged according to the first historical shower temperature when a shower is started;
specifically, by the method in the embodiment, the initial outlet water temperature can be closer to the temperature required by the user; thereby achieving a good user experience.
In some embodiments, as in the water temperature adjustment method described above, step S1 obtains first physiological status information of the first user before showering; and S2, acquiring second physiological state information in the shower of the first user, wherein the second physiological state information comprises the following information:
s1, acquiring breathing and/or heartbeat frequency of a first user before showering through a millimeter wave radar;
specifically, that is, the acquiring, by the millimeter wave radar, the first physiological status information of the first user before showering includes: at least one of a respiratory frequency and a heartbeat frequency;
s2, acquiring breathing and/or heartbeat frequency of the first user in the shower by a millimeter wave radar;
specifically, that is, the acquiring of the second physiological state information in the shower of the first user by the millimeter wave radar includes: at least one of a respiratory frequency and a heartbeat frequency;
in addition, when the breathing rate is acquired before showering, the breathing rate is also acquired in showering; when the heartbeat frequency is acquired before showering, the heartbeat frequency is also acquired in showering; when the respiratory frequency and the heartbeat frequency are obtained before showering, the respiratory frequency and the heartbeat frequency are also obtained in showering;
specifically, the millimeter wave radar is a radar that operates in a millimeter wave band (millimeter wave) for detection. Usually, the frequency domain of the millimeter wave is 30 to 300GHz, and the wavelength is 1 to 10 mm. Millimeter-wave radars have some of the advantages of both microwave and photoelectric radars, since the wavelength of millimeter-waves is between that of microwaves and centimeter waves:
compared with the centimeter wave seeker, the millimeter wave seeker has the characteristics of small volume, light weight and high spatial resolution. Compared with optical probes such as infrared, laser, television and the like, the millimeter wave probe has strong capability of penetrating fog, smoke and dust and has the characteristics of all weather and all day long. In addition, the anti-interference and anti-stealth capabilities of the millimeter wave seeker are also superior to those of other microwave seekers. The millimeter wave radar can distinguish and identify very small targets and can identify a plurality of targets simultaneously; the imaging device has the advantages of strong imaging capability, small volume and good maneuverability and concealment.

that is, if the second physiological state information is increased more than the first physiological state information, for example: when the heartbeat frequency rises too high during showering, the water temperature is possibly caused to be too high, and at the moment, the water temperature is properly reduced, so that a cooling strategy for reducing the outlet water temperature of the water heater is generated;
s32, when the drop amount of the second physiological state information compared with the first physiological state information exceeds a preset second threshold (for example, 10%), generating a temperature-rising strategy for increasing the outlet water temperature of the water heater;
that is, if the second physiological state information is decreased too much compared to the first physiological state information, for example: when the heartbeat frequency during showering is reduced too much, the water temperature is too low, and the water temperature should be raised properly, so that a temperature raising strategy for raising the outlet water temperature of the water heater is generated;
s33, when the variation of the second physiological state information compared with the first physiological state information does not exceed a first threshold and a second threshold, maintaining the current outlet water temperature of the water heater;
that is, if the amount of change of the second physiological state information from the first physiological state information is within a preset range (when the change does not exceed the first threshold value or the change does not exceed the second threshold value), it is determined that the current temperature is suitable for the user, and therefore the current outlet water temperature of the water heater is maintained.

specifically, when reducing water heater leaving water temperature, in order to prevent the upset condition of back because the temperature drops too much and leads to the temperature after the adjustment, adopt many times of micro-adjustment to carry out leaving water temperature adjustment, for example: the water temperature is adjusted by 2 degrees each time; after adjustment, if the rising amount of the detected second physiological state information compared with the first physiological state information still exceeds a preset first threshold value, the water temperature is still too high, and a cooling strategy is continuously generated; when the variation of the second physiological state information compared with the first physiological state information does not exceed the first threshold and the second threshold (for example, the variation is within 10% of the upper and lower limits, and the accuracy can be adjusted according to the actual use condition), the water temperature is determined to be suitable for the user, and the water temperature is not adjusted.
If the water outlet temperature of the water heater is increased according to the temperature-increasing strategy, the decrease amount of the second physiological state information compared with the first physiological state information still exceeds a preset second threshold, the temperature-increasing strategy is continuously generated, and the water heater is controlled according to the temperature-increasing strategy until the variation amount of the second physiological state information compared with the first physiological state information does not exceed the first threshold and the second threshold;
the specific adjustment and regulation method is similar to the cooling strategy, and is not repeated herein.
