[0053] like Figure 1 As shown, the present invention provides a bathroom intelligent hanging basket control system, which includes a data acquisition module 1, a processing server 2, a control execution module 3 and an early warning module 4. The system of the present invention ensures the safe and stable operation of the hanging basket by monitoring the use status of the bathroom hanging basket in real time, and effectively prevents accidents caused by overloading or tilting of the hanging basket.

[0054] Preferably, the data acquisition module 1 is used to collect the weight data, tilt angle data and use environment data of the hanging basket, and pre-process the collected data. In one embodiment of the present invention, the weight data is collected by a high-precision strain gauge weighing sensor with a measurement range of 0-50kg and a resolution better than 0.1kg. This range design fully considers the weight range of daily necessities such as towels and bathrobes commonly used in home bathrooms. The tilt angle data is collected by a dual-axis tilt sensor with a measurement range of ±30° and an accuracy better than 0.1°, which can detect the tilt state of the hanging basket in time. Environmental data includes humidity and hanging basket surface temperature, which are important parameters for evaluating the safety of the hanging basket.

[0055] Furthermore, the preprocessing in the present invention uses a sliding average filtering method to eliminate data jitter. Preferably, the sliding window length is set to 10 sampling points, and the sampling frequency is 10 Hz. In the embodiment of the present invention, the preprocessed data can more accurately reflect the actual load state of the hanging basket, and effectively avoid misjudgment caused by instantaneous interference.

[0056] like Figure 2 As shown, the data acquisition module 1 includes a weight acquisition unit 11, an angle acquisition unit 12 and an environment acquisition unit 13. Among them, the weight acquisition unit 11 adopts a weighing sensor with a waterproof level of IP67 to ensure reliable operation in the humid environment of the bathroom. In the preferred embodiment of the present invention, the angle acquisition unit 12 adopts a dual-axis MEMS tilt sensor with a temperature compensation function, and the measurement accuracy is not affected by the ambient temperature. The environment acquisition unit 13 includes a digital temperature and humidity sensor, wherein the humidity measurement range is 0-100% RH, and the temperature measurement range is 0-60°C, which meets the bathroom environment monitoring needs.

[0057] The processing server 2 is connected to the data acquisition module 1 for receiving preprocessed data and performing status evaluation and safety warning. In one embodiment of the present invention, the processing server 2 adopts a low-power microprocessor, has a moisture-proof and waterproof design, and has high reliability. Preferably, the status evaluation adopts a fuzzy judgment method, which comprehensively considers the weight, angle and environmental parameters to obtain the safety level of the hanging basket. In the present invention, the safety level is divided into three levels: safe, cautious and dangerous, and corresponding warning thresholds are set. For example, when the load exceeds 30kg or the tilt angle exceeds 15°, it enters the caution level, and when the load exceeds 40kg or the tilt angle exceeds 25°, it enters the dangerous level.

[0058] like Figure 3 As shown, the processing server 2 includes a data processing unit 21, a state evaluation unit 22 and a control strategy unit 23. The data processing unit 21 performs standardization processing on the received data to eliminate the range differences of different sensors. In a preferred embodiment of the present invention, the state evaluation unit 22 performs a state evaluation every 100ms to ensure that the system has good real-time performance. When an abnormal state is detected, the control strategy unit 23 will immediately generate a control instruction to achieve automatic leveling or load limitation through the control execution module 3.

[0059] Through the above technical solution, the bathroom intelligent hanging basket control system of the present invention has the following advantages: first, the system adopts a multi-sensor fusion method to comprehensively monitor the use status of the hanging basket; second, a graded warning mechanism is adopted to timely remind users to pay attention to safety; finally, it has an automatic leveling function to effectively prevent items from sliding. These features make the system of the present invention particularly suitable for intelligent safety protection in humid environments such as bathrooms. Figure 4 As shown, the control execution module 3 includes an instruction parsing unit 31, a leveling execution unit 32 and a limit protection unit 33. In one embodiment of the present invention, the instruction parsing unit 31 converts the control instruction sent by the processing server 2 into a specific execution signal. Preferably, the control instruction adopts a standard digital communication format, has a checksum and error correction function, and can effectively prevent errors in the signal during transmission.

[0060] In a preferred embodiment of the present invention, the leveling execution unit 32 uses a balancing mechanism driven by a micro-stepping motor, with a stepping accuracy of 1.8° and a self-locking function. When the hanging basket is detected to be tilted, the leveling execution unit 32 adjusts the horizontal state of the hanging basket by controlling the rotation of the stepping motor. Preferably, the leveling process adopts a flexible start-stop mode, and the rotation speed does not exceed 60rpm, so as to ensure that the leveling process is smooth and vibration-free, and prevent the items on the hanging basket from shaking or falling.

[0061] The limit protection unit 33 triggers the protection mechanism when overload or excessive tilt is detected. In the embodiment of the present invention, the unit adopts an electromagnetic locking device with a response time of less than 100ms. When the load exceeds 40kg or the tilt angle exceeds 25°, the limit protection unit 33 immediately locks the movable mechanism of the hanging basket to prevent accidents. Preferably, the locking mechanism has a manual release function, and the user can release the lock mechanically in an emergency.

[0062] like Figure 5 As shown, the warning module 4 includes a threshold judgment unit 41, a signal generation unit 42 and an audible and visual alarm unit 43. The threshold judgment unit 41 monitors the weight, tilt angle and other parameters of the hanging basket in real time. In one embodiment of the present invention, the warning threshold is divided into two levels: when the weight exceeds 30kg or the tilt angle exceeds 15°, a yellow warning is issued; when the weight exceeds 40kg or the tilt angle exceeds 25°, a red warning is issued. These threshold parameters are obtained based on a large amount of user usage data statistics, which can effectively balance safety and convenience of use.

[0063] The signal generating unit 42 generates corresponding warning signals according to different warning levels. In a preferred embodiment of the present invention, the unit is controlled by a low-power single-chip microcomputer, and the standby power consumption is less than 1mW. The sound and light alarm unit 43 includes a light-emitting diode and a buzzer, wherein the LED lamp adopts a high-brightness SMD package, which can be clearly identified even in the bright environment of the bathroom. Preferably, the sound pressure level of the buzzer is 75dB (measured at a distance of 10cm), and the alarm frequency can be selected as 2kHz or 4kHz, which can ensure the reminder effect without causing excessive noise.

[0064] The system of the present invention further includes a human-computer interaction module 5, which is in communication connection with the processing server 2. In the embodiment of the present invention, the human-computer interaction module 5 uses a waterproof touch screen with a display resolution of 320×240 pixels and a brightness of not less than 300cd / ㎡, ensuring clear display in a bathroom environment. Preferably, the touch screen uses capacitive touch technology, which can be reliably operated even in a humid environment.

[0065] The system of the present invention uses wireless communication to connect various functional modules. Preferably, wireless communication in the 2.4 GHz frequency band is used between the data acquisition module 1 and the processing server 2, and the transmission distance can reach 10 meters, which is enough to cover the space of an ordinary family bathroom. In a preferred embodiment of the present invention, the wireless communication adopts a low-power design, and the sensor module can work continuously for more than 6 months when powered by a button battery.

[0066] The above technical solution not only realizes the intelligent monitoring and protection of the bathroom hanging basket, but also has the characteristics of convenient installation and easy use in practical applications. The system avoids complex wiring engineering through wireless communication, and the waterproof design and low power consumption characteristics ensure reliable operation in the bathroom environment. In a preferred embodiment of the present invention, Bluetooth communication is used between the control execution module 3 and the processing server 2. Preferably, Bluetooth 5.0 technology is used, which has low power consumption characteristics, and reduces system power consumption while ensuring reliable communication. In one embodiment of the present invention, Bluetooth communication adopts a master-slave mode, with the processing server 2 as the master device and the control execution module 3 as the slave device. During the communication process, the data packet adopts a CRC check mechanism to effectively ensure the accuracy of data transmission. In addition, Bluetooth communication has strong anti-interference ability and can maintain a stable connection even in an environment where multiple electrical appliances coexist, such as a bathroom.

[0067] like Figure 6 As shown, the human-computer interaction module 5 includes a display unit 51, a setting unit 52 and an APP interaction unit 53. The display unit 51 adopts a 2.8-inch TFT liquid crystal screen with waterproof and anti-fog treatment. In a preferred embodiment of the present invention, the display interface adopts a partition display mode, important information such as load weight, tilt angle, etc. are displayed in large fonts, and warning information is marked with eye-catching colors. Preferably, the viewing angle of the display unit 51 is not less than 160°, and the display content can be clearly viewed at any position in the bathroom.

[0068] The setting unit 52 provides parameter configuration functions. In the embodiment of the present invention, the unit uses capacitive touch buttons, and the number of buttons is 4, which are used for menu switching, parameter increase and decrease, and confirmation operations. Preferably, the trigger force of the touch button is 200±50gf, which is the best experience value obtained after a large number of user tests. In addition, the button has an anti-mistouch function, which requires continuous touch for 0.5 seconds to activate, effectively avoiding misoperation in the case of water.

[0069] The APP interaction unit 53 provides the user with a remote control function. In a preferred embodiment of the present invention, the mobile terminal APP adopts a flat interface design, and the operation logic is simple and intuitive. Preferably, the APP has the following functional features: first, it can display the load status, tilt angle and other parameters of the hanging basket in real time; second, it supports the setting of warning thresholds, and the user can adjust the warning level according to actual needs; finally, it has a historical data statistics function, which can record and analyze the use of the hanging basket. In one embodiment of the present invention, the APP adopts a timed refresh mechanism with a refresh interval of 1 second, which not only ensures the real-time nature of the data, but also avoids the power consumption problem caused by too frequent communication.

[0070] The status evaluation unit 22 of the present invention also has the function of using time statistics and maintenance reminder. Preferably, the system records the cumulative use time of the hanging basket, and when the preset maintenance cycle is reached, the maintenance reminder is pushed through the APP. In the embodiment of the present invention, the default value of the maintenance cycle is set to 3 months, and the user can adjust it according to the actual frequency of use. In addition, the status evaluation unit 22 will also record the load history of the hanging basket. When the cumulative number of overloads reaches the set threshold, the system will recommend a safety check. Preferably, the threshold is set to 50 times, which fully considers the design service life and safety margin of the product.

[0071] Through the above technical solution, the bathroom intelligent hanging basket control system of the present invention not only realizes the basic safety monitoring function, but also provides a rich human-computer interaction mode and intelligent services. The introduction of the mobile terminal APP makes the operation of the system more convenient, and the maintenance reminder function effectively extends the service life of the product. The whole system adopts a modular design, and each functional unit can be flexibly configured according to user needs, which has strong practicality and promotion value.
