BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The drawings are only used to illustrate the embodiments and are not considered as a limitation to the present invention. And throughout the drawings, the same reference numerals are used to represent the same components. In the drawings:

[0048] Figure 1 It shows a schematic flow chart of the bathroom intelligent lighting adjustment method provided by the embodiment of the present invention;

[0049] Figure 2 It shows a schematic structural diagram of the computer device provided by the embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0050] Hereinafter, the exemplary embodiments of the present invention will be described in more detail with reference to the drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein.

[0051] Figure 1The figure shows a flowchart of the bathroom intelligent lighting adjustment method provided by an embodiment of the present invention, which is executed by a computer device. The computer device can be an intelligent adjustment device set in the bathroom and is applied to the bathroom intelligent lighting adjustment system. The system is based on local edge computing. The system includes multiple types of lighting devices and multiple types of sensing devices set at multiple preset positions in the bathroom. The sensing devices include pyroelectric arrays, sound extraction devices, and temperature sensing devices, which are not specifically limited in the present invention. As Figure 1 shown, the method includes the following steps:

[0052] Step 110: Obtain the current bathroom status data in real time.

[0053] Among them, the current bathroom status data includes the current time, the current ambient temperature, the current human body status of the user, and the current water flow sound status.

[0054] Among them, after obtaining the current bathroom status data in real time, it is determined according to the current human body status of the user. When the user enters the bathroom, the identity of the user entering the bathroom is determined according to the face device. The target user preference is determined according to the identity. The target user preference can be the preference filled in by the user when registering on the system. When the face of the user is recognized, the corresponding user preference is retrieved from the database. The user preference can include lighting, music, etc.

[0055] Step 120: When it is determined that the user enters the shower area according to the current human body status and the shower is turned on according to the current water flow sound status, it is determined that the user enters the shower state.

[0056] Among them, in an embodiment of the present invention, when the following conditions are met simultaneously, it is determined that the user enters the shower state:

[0057] 1. The human body status sensor confirms that the user is in the shower area (lasting ≥ 5 seconds).

[0058] 2. The water flow sound classification model outputs "shower on".

[0059] 3. The humidity sensor detects that the humidity rising rate > 5% / minute.

[0060] Among them, the embodiment of the present invention also performs feedback delay and misjudgment processing. When the time from detecting the water flow sound to the final determination needs to be ≤ 2 seconds, by setting like this, it can be avoided that the user experience is delayed. Among them, if the water flow sound lasts < 3 seconds and the humidity does not rise, it is detected as a false positive. When it is detected as a false positive, it is misjudged as the shower being turned on. The hardware verification of the water flow sensor is performed to determine whether it is a false negative, that is, the shower being turned on is missed.

[0061] Step 130: Start the target shower mode according to the user information of the user, the current time, the current ambient temperature, and the current ambient humidity.

[0062] Among them, according to the target user preference, the current time, the current ambient temperature, and the current ambient humidity, start the target shower mode. In the embodiment of the present invention, the target shower mode includes the lighting state of the lighting device in the shower area, the ventilation mode, and the room temperature adjustment information; the target shower mode is one of multiple shower modes; the multiple shower modes include the bedtime shower mode and the morning shower mode; the lighting state is determined according to the lighting adjustment decision algorithm.

[0063] Among them, the lighting device in the shower area includes a first lighting device arranged above the shower device and a lighting strip arranged on the ground and / or side wall of the shower area. In the embodiment of the present invention, input the user information of the user, the current time, the current ambient temperature, and the current ambient humidity into the lighting adjustment decision algorithm to determine the first lighting state of the first lighting device above the shower device; and the second lighting state of the lighting strip to obtain the lighting state of the shower area; the first lighting state includes the first lighting brightness, the first lighting color, and the first lighting color temperature; the second lighting state includes the second lighting brightness, the second lighting color, and the second lighting color temperature.

[0064] Among them, the process of determining the first lighting brightness range is:

[0065] Obtain the difference between the current time and the user's preset sleep time;

[0066] Calculate the user's movement amplitude and frequency through pyroelectric array data to determine the user's current activity intensity;

[0067] Substitute the time factor into the basic brightness curve formula to obtain the basic brightness range; among them, the basic brightness curve formula is:

[0068] Basic brightness = 200 - 150×(time factor 0.7 )

[0069] Determine the first lighting brightness range according to the current activity intensity, the basic brightness, and the user brightness preference coefficient. Among them, current activity intensity × 50, and the user brightness preference coefficient range is 0.8 - 1.2. Among them, the first lighting brightness range is between 50 - 250 lux.

[0070] Among them, the process of determining the first lighting color temperature range is:

[0071] Substitute the time factor into the basic color temperature curve formula to obtain the basic color temperature range; among them, the basic color temperature curve formula is: Basic color temperature = 3000 - 800×(time factor 0.5)

[0072] Calculate the temperature compensation based on the ambient temperature to obtain the color temperature compensation value. Among them, when the ambient temperature is lower than 25°C, for every 1°C decrease, the color temperature increases by 10K, and calculate the temperature compensation value: max(0, 25 - current temperature) × 10. According to the color temperature compensation value and the basic color temperature range, obtain the first lighting color temperature range. Among them, the first color temperature range is in the range of 2000 - 3000K.

[0073] In the embodiment of the present invention, the determination process of the spectral parameters in the first lighting color range is as follows:

[0074] Calculate the blue light suppression coefficient according to the age of the user, and calculate the blue light ratio limit according to the time factor; determine the spectral parameters in the first lighting color according to the blue light suppression coefficient and the blue light ratio limit. Specifically, adjust the blue light sensitivity according to the user's age: adjust the blue light sensitivity according to the user's age: blue light suppression coefficient = 0.8 + 0.2 × (user age / 70). Calculate the blue light ratio limit according to the time factor: maximum blue light ratio = 0.15 × blue light suppression coefficient × (1 - time factor 0.6) , generate spectral parameters, among which, the red ratio is: 0.5 + 0.3 × time factor, the green ratio: 0.35 - 0.1 × time factor. Blue ratio: take the smaller value between the calculated maximum blue light ratio and 0.15. Amber ratio: 0.15 + 0.1 × time factor. Among them, the spectral adjustment adopts blue light suppression technology and realizes it by controlling the mixing ratio of LED lamp beads. According to the calculated spectral ratio, control the output power of RGBW four-color LED lamp beads; realize precise spectral mixing through PWM dimming technology to obtain LED mixing control.

[0075] Among them, input the user information of the user, the current time, the current ambient temperature and the current ambient humidity into the lighting adjustment decision algorithm to obtain the lighting state of the shower area, including:

[0076] Determine the time category according to the current time; the time category includes the morning period or the night period; among them, the morning period can be set within 2 hours after sunrise to promote awakening. The night period can be set from 21:30 to 24:00, so it is necessary to consider avoiding the suppression of melatonin by the shower and the lighting during the shower.

[0077] When the current time is at night, determine the first lighting brightness, the first lighting color and the first lighting color temperature of the first lighting device according to the melatonin suppression curve of the user, and determine the second lighting brightness, the second lighting color and the second lighting color temperature of the lighting strip according to the compensation mechanism. That is, the first lighting device is the main lighting and is directly determined by the melatonin curve. The lighting strip on the ground and / or side wall of the shower area supplements the ground contour light for anti-slip reminder.

[0078] In an embodiment of the present invention, according to the melatonin inhibition curve of the user, user information, and the current environmental humidity, a first lighting brightness range, a first lighting color range, and a first lighting color temperature range are determined; wherein, the melatonin inhibition curve is:

[0079]

[0080] Where: I melatonin represents the melatonin inhibition rate, which can be 0 - 1. B is the illumination brightness (lux); B0: reference brightness (100 lux); λmax is the spectral peak wavelength, and k represents the individual sensitivity coefficient. The system calculates the impact of the current lighting scheme on melatonin secretion in real time through this model and dynamically adjusts the parameters to ensure that the inhibition rate is controlled within a safe range (<30%).

[0081] Among them, in an embodiment of the present invention, according to the first lighting brightness range, the first lighting color range, and the first lighting color temperature range, a genetic algorithm is used to simulate the biological evolution process, and the optimal parameter combination is searched in the solution space; the optimal parameter combination is converted into an identifiable control instruction for the first lighting device to obtain the first lighting state.

[0082] Specifically, iterative processing is performed through a genetic algorithm to obtain the final first lighting state, including the following steps:

[0083] Set the population size, the maximum number of generations of evolution, and the optimization objective function, where the optimization objective function includes melatonin protection, visual clarity, and energy efficiency; wherein, each individual includes lighting brightness, lighting color, and lighting color temperature;

[0084] Randomly generate brightness values, color temperature values, and color values for each individual;

[0085] According to the objective function of each individual's optimization objective, calculate the melatonin protection fitness, visual clarity fitness, and energy efficiency fitness;

[0086] Through Pareto optimality, calculate the boundary distance of each individual on each optimization objective function, and perform selection operations, adaptive crossover operations, and mutation operations to determine elite individuals from the Pareto optimality to replace the worst-performing individuals;

[0087] Perform the above iterative processing to obtain the optimal parameter combination searched in the solution space.

[0088] Through the above algorithm, the system realizes fine control of brightness, color temperature, and spectrum, which not only meets the visual needs of users at night but also minimizes the interference with melatonin secretion to scientifically protect the sleep quality of users. Compared with traditional lighting solutions, this intelligent adjustment mechanism can reduce the melatonin inhibition rate by 40%-60%, significantly improving sleep quality and mental state the next day.

[0089] Step 140: When the shower is completed, gradually turn off the lights in the shower area in a fading manner, and at the same time, gradually turn on the lights in the dressing area in a brightening manner.

[0090] Among them, when it is detected by the water flow sensor that the shower water flow has stopped for ≥30 seconds, or when the humidity sensor detects that the rising trend of humidity has stopped and starts to decline, it is determined that the shower is completed. After the shower is completed,

[0091] The brightness fade in the shower area is as follows: The initial brightness is the current brightness of the lights in the shower area, 50 lux in night mode, and 300 lux in morning mode. When the target brightness is 0 lux, it is completely turned off.

[0092] Among them, the lights in the dressing area are gradually turned on in a brightening manner in the opposite way.

[0093] Step 150: When it is detected that the user leaves the bathroom, turn off the lighting device in the bathroom and turn on the ventilation and dehumidification mode.

[0094] In the embodiment of the present invention, the current bathroom status data is obtained in real time; the current bathroom status data includes the current time, the current environmental temperature, the current human body status of the user, and the current water flow sound status; when it is determined according to the current human body status that the user enters the shower area and it is determined according to the current water flow sound status that the shower is turned on, it is determined that the user enters the shower state; according to the user information of the user, the current time, the current environmental temperature, and the current environmental humidity, the target shower mode is started; when the shower is completed, gradually turn off the lights in the shower area in a fading manner, and at the same time, gradually turn on the lights in the dressing area in a brightening manner; when it is detected that the user leaves the bathroom, turn off the lighting device in the bathroom and turn on the ventilation and dehumidification mode, which can effectively combine the current time and environmental information to determine the lighting adjustment that is most suitable for the user's shower method.

[0095] Furthermore, in the process of lighting adjustment in the embodiment of the present invention, the current environmental humidity and the melatonin inhibition curve are combined. Since the environmental humidity during showering causes the brightness, color temperature, and color of the lights to be affected to a certain extent, when considering the setting of the light state, the influence of the current environmental humidity needs to be considered. Moreover, through the coordinated optimization of the brightness, color temperature, and color of the bathroom lights, the multi-objective requirements of melatonin protection, visual clarity, and energy efficiency can be simultaneously met.

[0096] In another embodiment of the present invention, it is assumed that the user enters the bathroom at 22:00 at night to prepare for a shower. After the system is started:

[0097] The ambient temperature is collected in real time as 26°C and the humidity is 65%, and information such as the user's preset sleep time of 23:00 and age of 35 years is obtained.

[0098] Start the multi-objective optimization program based on the genetic algorithm:

[0099] Initialize the population and generate 100 individuals containing random lighting parameters.

[0100] Calculate the time factor. At this time, it is 1 hour until the sleep time, and the time factor is approximately 0.83.

[0101] Calculate the fitness values of the three objective functions for each individual.

[0102] Perform non-dominated sorting and crowding distance calculation to determine the Pareto optimal front.

[0103] Select parent individuals through the tournament selection method, perform adaptive crossover and intelligent mutation operations, and perform elite retention.

[0104] Repeat the above steps of fitness evaluation, selection, crossover, mutation, and elite retention until the maximum number of generations of evolution is reached or the convergence condition is satisfied.

[0105] Finally, the optimal lighting control parameters are obtained, such as a brightness of 120 lux, a color temperature of 2800 K, a spectral ratio of red 0.4, green 0.3, blue 0.15, and amber 0.15.

[0106] The lighting control module adjusts the bathroom lights to the corresponding state according to the above parameters, while ensuring clear vision for the user, reducing the impact on melatonin secretion, and achieving reasonable utilization of energy.
