[0002] In daily life, the bathroom is a frequently used space, and its environmental quality is crucial to the comfort and health of users. Traditional bathroom environment adjustment methods usually rely on manual operations, such as manually adjusting air conditioners, humidifiers or ventilation equipment, which is not only cumbersome but also easily affected by human factors, resulting in the bathroom environment not always being kept in the most suitable state.

[0003] Some existing smart home systems use sensors to collect environmental data and adjust devices in real time, but these systems usually lack accurate recognition and intelligent adjustment of individual user preferences. Although some systems can automatically adjust the environment based on environmental parameters (such as temperature, humidity, air quality, etc.), they often cannot provide personalized environmental settings according to the needs of different family members. For example, different family members may have different needs for temperature, humidity, and air quality, and traditional smart systems cannot provide customized services based on the preferences and usage habits of different family members.

[0004] In addition, although existing remote control systems can enable users to remotely operate and adjust equipment, they are generally limited to simple parameter adjustments and lack intelligent situational awareness and personalized services. In actual applications, users often need to constantly adjust settings manually, and the system lacks the ability to automatically learn and self-adjust. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 It is a schematic diagram of the intelligent control system module of the present invention. DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1 , the present invention provides the following technical solutions: The intelligent control system of bathroom environment based on the Internet of Things includes: Environmental parameter collection module, used for: The environmental parameter data in the bathroom is monitored in real time through sensors, including temperature sensors, humidity sensors and gas sensors, which are deployed inside the bathroom; Environmental intelligent adjustment module, used for: Based on the environmental parameter data and the target environmental parameters set by the user, the smart devices are controlled to adjust the environment in the bathroom, and the smart devices include ventilation equipment, air conditioning equipment and humidifier; Remote monitoring control module for: Interact with the mobile APP terminal remotely, display the environmental parameter data of the bathroom in real time on the mobile APP terminal, receive the remote control instructions and target environmental parameter setting instructions from the mobile APP terminal, remotely control the smart device based on the remote control instructions, and record the user information of the mobile APP terminal that issued the remote control instructions; Individual adjustment module for: Obtain user information and remote control instructions, and extract the adjustment instruction content and instruction sending time in the remote control instructions; Extract the current user information's environmental preference based on the content of the adjustment instruction, expand the time period of the instruction sending time and generate a common time period; Associate each user's information with their environment preferences and frequently used time periods; When the time reaches the commonly used time period, the user information corresponding to the current commonly used time period is read, and the smart device is automatically adjusted based on the environmental preferences associated with the user information; When it is not in the usual time period, switch to the environment intelligent adjustment module to control the smart device; Subscriber Identity Module, used for: The user information entering the bathroom is identified through facial recognition and Bluetooth wireless positioning. Specifically, the facial information of the user entering the bathroom is collected by a camera installed at the bathroom entrance for facial recognition, and the Bluetooth device carried by the user is identified through a Bluetooth sensor installed in the bathroom. The Bluetooth device includes a smartphone and a smart bracelet with Bluetooth function. When it is not in the usual time period, the identified user information is sent to the personalized adjustment module.

[0022] In the above embodiment, through the real-time collection of environmental parameter data and the automatic adjustment of intelligent devices, the system can adjust the temperature, humidity and air quality in the bathroom according to actual needs. For example, when the temperature is too high, the system automatically adjusts the air conditioning equipment; when the humidity is too low, the system activates the humidifier; when the air quality decreases, the system starts the ventilation equipment to ensure that the environment in the bathroom always meets the user's comfort requirements. Since the system can make precise adjustments according to environmental changes, when the environmental conditions are close to the target environmental parameters, the system will automatically stop adjusting, thereby avoiding energy waste. By automatically controlling temperature, humidity and air quality, the system significantly reduces energy consumption and effectively improves the efficiency of equipment use.

[0023] In the above embodiment, the system can identify the user and adjust the environment according to the user's environmental preferences through the collaboration of facial recognition, Bluetooth positioning and remote control modules. By tracking the user's habits and needs over a long period of time, the system can learn and optimize the environmental adjustment strategy, thereby providing a customized environmental control experience. This personalized adjustment not only improves the user's comfort, but also makes the bathroom environment more in line with the life needs of each user.

[0024] In the above embodiment, the remote monitoring function allows users to view the environmental parameter data of the bathroom through the mobile APP anytime and anywhere, and remotely operate the smart device according to needs. This convenient control method provides users with great flexibility and control.

[0025] In the above embodiment, by intelligently adjusting the air quality (such as improving air circulation by controlling ventilation equipment), the risk of mold, odor and bacteria breeding is reduced, thereby indirectly improving the sanitation of the bathroom. This allows users to enjoy a comfortable environment while reducing the workload of cleaning.

[0026] The environmental intelligent adjustment module is also used for: Receiving environmental parameter data, the environmental parameter data including temperature parameter, humidity parameter and air quality parameter, wherein the air quality parameter includes CO2 concentration and VOC concentration; receiving target environmental parameters, wherein the target environmental parameters include a target temperature value, a target humidity value, and a target air quality parameter; Set a tolerance threshold, compare the difference between the calculated environmental parameter data and the target environmental parameter, and when the difference is greater than the tolerance threshold, control the smart device to adjust the environment in the bathroom according to the target environmental parameter; When the environmental parameter data reaches the target environmental parameter, the adjustment operation of the environmental intelligent adjustment module is terminated.

[0027] In the above embodiment, the environment intelligent adjustment module obtains the environment parameter data in real time through the sensor and compares it with the set target environment parameter. When it is detected that the difference between the environment parameter data and the target environment parameter exceeds the set tolerance threshold, the system automatically activates the corresponding intelligent device (such as air conditioner, humidifier, ventilation equipment) for adjustment. This intelligent adjustment method ensures that the environment parameters are always within the preset comfort range, thereby improving the user experience.

[0028] In the above embodiment, the working state of the device is automatically adjusted according to the difference between the environmental parameter data and the target environmental parameter. When the environmental condition reaches the target value, the adjustment module will stop controlling the device to avoid unnecessary energy waste. Especially when the environmental parameters such as air quality, temperature and humidity change greatly, the intelligent adjustment module can adjust the power of the device according to actual needs to maximize the energy utilization efficiency of the system.

[0029] In the above embodiment, by setting the tolerance threshold, the system can automatically make corresponding adjustments according to environmental changes. For example, if a large temperature change is detected, the system will quickly start the air conditioning equipment to adjust the temperature; if the air quality is poor, the system will automatically start the ventilation equipment to purify the air. This adaptive environmental adjustment capability can ensure that the user is always in the most comfortable environment without manual intervention.

[0030] In the above embodiment, accurate environmental adjustment not only optimizes the comfort of the bathroom, but also can be adjusted in time according to environmental changes in different time periods. For example, during periods of time when temperature and humidity change greatly (such as morning and evening), the system can preset environmental parameters in advance to ensure that the environmental conditions are adjusted to the best state when the user enters the bathroom.

[0031] Specifically, the environment intelligent adjustment module is also used for: When the difference between the environmental parameter data and the target environmental parameter is not greater than the tolerance threshold, the data values ​​of the temperature parameter and the humidity parameter contained in the environmental parameter data are extracted in real time; Obtaining the temperature and humidity comprehensive fluctuation coefficients corresponding to the temperature and humidity parameters according to the data values ​​of the temperature and humidity parameters included in the environmental parameter data; The temperature and humidity comprehensive fluctuation coefficient is obtained by the following formula: ; Where G represents the comprehensive fluctuation coefficient of temperature and humidity; n represents the number of data collection times of the temperature sensor; m represents the number of data collection times of the humidity sensor; T i represents the temperature data value corresponding to the i-th collection of the temperature sensor; T p W represents the average value of the temperature data collected by the temperature sensor n times; tiW represents the humidity data value of the corresponding bathroom collected by the temperature sensor for the i-th time; p W represents the average value of humidity data corresponding to m times of humidity sensor collection; s represents the standard deviation of humidity data corresponding to m acquisitions by the humidity sensor; W i represents the humidity data value corresponding to the i-th collection of the humidity sensor; T wi represents the temperature data value of the corresponding bathroom collected by the humidity sensor for the i-th time; T s Indicates the standard deviation of temperature data corresponding to n acquisitions by the temperature sensor; Comparing the temperature and humidity comprehensive fluctuation coefficient with a preset temperature and humidity fluctuation coefficient threshold; When the temperature and humidity comprehensive fluctuation coefficient exceeds a preset temperature and humidity fluctuation coefficient threshold, the collection frequencies of the temperature sensor, humidity sensor and gas sensor are adjusted.

[0032] The technical effect of the above technical scheme is as follows: the scheme first determines whether the difference between the environmental parameter data and the target environmental parameter is not greater than the tolerance threshold, which ensures that data collection and analysis are performed only when the environmental state is close to the target state, thereby improving the real-time and pertinence of data processing. By extracting the data values ​​of the temperature parameter and the humidity parameter in real time, the temperature and humidity conditions of the current environment can be accurately reflected, providing a reliable basis for subsequent analysis. By introducing the temperature and humidity comprehensive fluctuation coefficient G, the coefficient comprehensively considers the fluctuation of temperature and humidity, including their respective average values, standard deviations, and cross-influences (such as the association between bathroom humidity and temperature data), thereby providing a comprehensive environmental fluctuation evaluation index. This comprehensive evaluation method is more comprehensive than considering temperature or humidity fluctuations alone, and can more accurately reflect the stability and comfort of environmental conditions. The temperature and humidity comprehensive fluctuation coefficient is compared with the preset temperature and humidity fluctuation coefficient threshold, and the acquisition frequency of the temperature sensor, humidity sensor, and gas sensor is intelligently adjusted according to the comparison result. When the environmental fluctuation is large, increasing the acquisition frequency can more effectively monitor environmental changes; when the environment is relatively stable, reducing the acquisition frequency can save resources and extend the life of the sensor. By intelligently adjusting the acquisition frequency, the scheme can optimize the use efficiency of the sensor and reduce unnecessary energy consumption while ensuring the accuracy of environmental monitoring. This has important energy-saving significance for systems that require long-term monitoring of environmental conditions. Real-time monitoring and intelligent adjustment can ensure that environmental conditions remain within the preset comfort range, thereby improving the user experience in specific environments (such as bathrooms). Especially in environments that are sensitive to temperature and humidity, the application of this technical solution can significantly improve user satisfaction and comfort.

[0033] In summary, this technical solution extracts and analyzes environmental parameter data in real time, introduces the comprehensive fluctuation coefficient of temperature and humidity for comprehensive evaluation, and intelligently adjusts the sensor acquisition frequency according to the evaluation results, thereby achieving accurate monitoring and intelligent management of environmental conditions, with significant energy-saving effects and improved user comfort.

[0034] Specifically, when the temperature and humidity comprehensive fluctuation coefficient exceeds a preset temperature and humidity fluctuation coefficient threshold, the acquisition frequency of the temperature sensor and the humidity sensor is adjusted, including: When the temperature and humidity comprehensive fluctuation coefficient exceeds a preset temperature and humidity fluctuation coefficient threshold, extracting the temperature and humidity comprehensive fluctuation coefficient; Extract the currently adjusted acquisition frequency of the temperature sensor and humidity sensor and the temperature and humidity comprehensive fluctuation coefficient corresponding to each acquisition frequency adjustment; The temperature acquisition frequency adjustment coefficient and humidity acquisition frequency adjustment coefficient corresponding to the temperature sensor and the humidity sensor are obtained by using the number of acquisition frequencies currently experienced by the temperature sensor and the humidity sensor and the temperature and humidity comprehensive fluctuation coefficient corresponding to each acquisition frequency adjustment; The temperature acquisition frequency adjustment coefficient is obtained by the following formula: ; Among them, K t represents the temperature acquisition frequency adjustment coefficient; G represents the comprehensive fluctuation coefficient of temperature and humidity; k represents the number of acquisition frequencies that have been adjusted corresponding to the temperature sensor; G i represents the comprehensive fluctuation coefficient of temperature and humidity corresponding to the temperature sensor when the collection frequency is adjusted for the i-th time; P i represents the acquisition frequency adjustment ratio when the temperature sensor adjusts the acquisition frequency for the i-th time; T c Indicates the specific value corresponding to the target temperature value; T gi represents the temperature data value of the bathroom when the temperature sensor adjusts the collection frequency for the i-th time; G pt It represents the average value of the comprehensive fluctuation coefficient of temperature and humidity when the temperature sensor adjusts the collection frequency k times; At the same time, the humidity collection frequency adjustment coefficient is obtained by the following formula: ; Among them, K w represents the humidity acquisition frequency adjustment coefficient; G represents the temperature and humidity comprehensive fluctuation coefficient; s represents the number of acquisition frequencies that have been adjusted corresponding to the humidity sensor; G j P represents the comprehensive fluctuation coefficient of temperature and humidity when the humidity sensor adjusts the acquisition frequency for the jth time; j W represents the ratio of the acquisition frequency adjustment amplitude when the humidity sensor adjusts the acquisition frequency for the jth time; cIndicates the specific value corresponding to the target humidity value; W gj G represents the humidity data value of the bathroom when the humidity sensor adjusts the collection frequency for the jth time; pw It represents the average value of the comprehensive fluctuation coefficient of temperature and humidity when the humidity sensor adjusts the collection frequency s times; The temperature acquisition frequency adjustment coefficient and the humidity acquisition frequency adjustment coefficient are used to adjust the acquisition frequencies of the temperature sensor and the humidity sensor, and the adjusted acquisition frequencies of the temperature sensor and the humidity sensor are obtained by the following formula: ; Among them, F t and F w Indicates the acquisition frequency of the adjusted temperature sensor and humidity sensor; F t0 and F w0 Indicates the acquisition frequency of the temperature sensor and humidity sensor before adjustment; K t Indicates the temperature acquisition frequency adjustment coefficient; K w Indicates the humidity collection frequency adjustment coefficient.

[0035] The technical effect of the above technical solution is: the solution monitors the comprehensive fluctuation coefficient of temperature and humidity in real time, and dynamically adjusts the acquisition frequency of the temperature sensor and the humidity sensor according to its changes. This dynamic adjustment mechanism enables the system to respond to environmental changes more flexibly and improve the accuracy and response speed of monitoring. The temperature acquisition frequency adjustment coefficient and the humidity acquisition frequency adjustment coefficient are calculated by complex formulas using historical acquisition frequency adjustment data (including the number of acquisition frequencies, the comprehensive fluctuation coefficient of temperature and humidity at each adjustment, the acquisition frequency adjustment amplitude ratio, etc.). This data-based intelligent decision-making method makes the adjustment more accurate and scientific, avoiding the waste of resources and inaccurate monitoring caused by blind adjustment. By adjusting the acquisition frequency, the system can minimize unnecessary acquisition operations while ensuring monitoring accuracy, thereby saving sensor resources and system energy consumption. This has important economic significance for environmental monitoring systems that need to run for a long time. Dynamically adjusting the acquisition frequency helps the system run more stably. In the case of large fluctuations in temperature and humidity, increasing the acquisition frequency can ensure that the system captures environmental changes in a timely manner to avoid false alarms or missed alarms; while in the case of relatively stable temperature and humidity, reducing the acquisition frequency can reduce the system load and improve the stability and reliability of system operation. Through precise environmental monitoring and intelligent frequency adjustment, the system can provide users with a more comfortable and stable environment. This has a significant effect on improving user experience for places that require strict control of environmental conditions (such as data centers, laboratories, etc.). This solution is not only applicable to temperature sensors and humidity sensors, but can also be extended to other types of sensors, such as gas sensors. At the same time, the formulas and parameters in the solution can be adjusted and optimized according to specific application scenarios to adapt to different monitoring needs and environmental conditions.

[0036] In summary, this technical solution achieves accurate monitoring and intelligent management of environmental conditions by introducing the temperature and humidity comprehensive fluctuation coefficient and intelligent frequency adjustment mechanism. This solution not only improves the dynamic adaptability and intelligence level of the system, but also optimizes resource utilization and system stability, providing users with a more comfortable and reliable environmental monitoring experience.

[0037] Specifically, when the temperature and humidity comprehensive fluctuation coefficient exceeds a preset temperature and humidity fluctuation coefficient threshold, the acquisition frequency of the gas sensor is adjusted, including: When the temperature and humidity comprehensive fluctuation coefficient exceeds the preset temperature and humidity fluctuation coefficient threshold, the temperature and humidity comprehensive fluctuation coefficient is retrieved; Extract the currently adjusted acquisition frequency of the gas sensor and the CO2 concentration and VOC concentration corresponding to each acquisition frequency adjustment; Obtaining a gas collection frequency adjustment coefficient corresponding to the gas sensor using the currently adjusted collection frequency of the gas sensor and the CO2 concentration and VOC concentration corresponding to each collection frequency adjustment; The gas collection frequency adjustment coefficient is obtained by the following formula: ; Among them, K q represents the gas collection frequency adjustment coefficient; G represents the temperature and humidity comprehensive fluctuation coefficient; x represents the number of times the gas sensor has undergone adjustment in the collection frequency; G qj represents the comprehensive fluctuation coefficient of temperature and humidity when the gas sensor adjusts the collection frequency for the i-th time; C i and V i represents the CO2 concentration and VOC concentration of the gas sensor corresponding to the i-th adjustment of the acquisition frequency; C m and V m Indicates the target CO2 concentration and target VOC concentration included in the target air quality parameters; The gas collection frequency adjustment coefficient is used to adjust the collection frequency of the gas sensor, and the adjusted collection frequency of the gas sensor is obtained by the following formula: ; Among them, F q Indicates the acquisition frequency of the adjusted gas sensor; F q0 Indicates the acquisition frequency of the gas sensor before adjustment; K q Indicates the gas sampling frequency adjustment coefficient.

[0038] The technical effect of the above technical solution is: by comparing the temperature and humidity comprehensive fluctuation coefficient with the preset threshold, the adjustment of the gas sensor acquisition frequency is triggered when the threshold is exceeded, which ensures that when the environmental conditions fluctuate greatly and may affect the air quality, the system can monitor the concentration of key gases such as CO2 and VOC more frequently, thereby improving the accuracy of air quality monitoring. The solution uses the historical acquisition frequency adjustment data of the gas sensor (including the number of acquisition frequencies, the temperature and humidity comprehensive fluctuation coefficient at each adjustment, the CO2 concentration and the VOC concentration) to calculate the gas acquisition frequency adjustment coefficient. This intelligent adjustment mechanism based on historical data enables the system to dynamically adjust the acquisition frequency according to the actual changes in environmental conditions, avoiding the waste of resources or insufficient monitoring problems that may be caused by fixed frequency acquisition. By dynamically adjusting the acquisition frequency of the gas sensor, the system can minimize unnecessary acquisition operations while ensuring monitoring accuracy. This helps to reduce sensor energy consumption and extend the service life of the sensor, thereby achieving resource optimization and energy saving effects. When the environmental conditions change significantly, the system can quickly adjust the acquisition frequency of the gas sensor to capture the changing trend of air quality more quickly. This improves the response speed of the system, allowing the system to issue warnings or take corresponding measures more promptly to ensure the safety of ambient air quality. Accurate air quality monitoring and intelligent frequency adjustment mechanism enable the system to provide users with a more comfortable and healthy indoor environment. This has a significant effect on improving user experience for places where air quality needs to be strictly controlled (such as offices, schools, hospitals, etc.). This solution is not only suitable for the monitoring of gases such as CO2 and VOC, but can also be extended to the monitoring of other gases according to actual needs. At the same time, the formulas and parameters in the solution can be adjusted and optimized according to specific application scenarios to adapt to different monitoring needs and environmental conditions. In addition, the modular design of the system makes subsequent maintenance and expansion easier.

[0039] In summary, this technical solution achieves accurate monitoring and intelligent management of ambient air quality by introducing the temperature and humidity comprehensive fluctuation coefficient and the intelligent gas sensor acquisition frequency adjustment mechanism.
