[0026] In order to enable those skilled in the art to better understand the technical solutions in one or more embodiments of this specification, the technical solutions in one or more embodiments of this specification will be clearly and completely described below in conjunction with the drawings in one or more embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on one or more embodiments of this specification, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this document.

[0027] With the continuous development of Internet of Things (IoT) technology and the continuous improvement of people's living standards, smart home devices are becoming more and more common. Smart home devices are gradually equipped with networking capabilities, allowing users to remotely control each smart home device through the Internet or configure operation strategies for smart home devices through the network.

[0028] Existing smart home devices mainly include smart speakers, smart curtains, smart lamps and other devices, which work with gateways to realize corresponding functions. However, the application level of smart home is relatively low among the elderly and children, especially empty-nest elderly or left-behind children. Their home environment cannot accommodate the layout of too many smart devices, and distant relatives cannot understand the physical condition and emotional interaction needs of the elderly or children at home in a timely manner.

[0029] In order to solve the above problems, the present invention provides a smart bed, the schematic diagram of which is as follows: Figure 1 As shown, the smart bed comprises at least a bed body 1, a headboard 2 and a mattress 3. A control panel 4 is provided on the headboard 2. The structural diagram of the control panel 4 is shown in FIG. Figure 2 As shown, it at least includes a touch display screen 41, a controller 42 and a communication module 43 coupled in sequence.

[0030] During actual use, the touchscreen 41 can be used to set the functions of the smart bed or display data such as time and temperature. In this embodiment, the touchscreen 41 can also be used to display electronic photos of loved ones. The home user can alleviate their longing for their loved ones by viewing or touching the displayed photos. The controller 42 can count the number of times the home user touches the electronic photos. When the number exceeds a first threshold, it determines that the home user has a high emotional need for their loved ones. The controller 42 then sends emotional interaction need information to the loved ones via the communication module 43, allowing the distant family member to promptly initiate a voice or video call with the home user upon receiving the emotional interaction need information. This embodiment utilizes the intelligent improvement of a bed that is essential for the home, giving it control and communication functions. The home user does not need to set up or learn other smart devices; simply by touching the electronic photos, they can reflect their emotional interaction needs. The operation is intuitive and simple. Remote relatives can also promptly understand the home user's emotional needs through the need information reflected by the smart bed, thereby improving the user's quality of life and the distant family member's understanding of the home user. In this embodiment, the first threshold value can be set according to the user's own needs, and this embodiment does not limit the specific number of times.

[0031] In some embodiments, the control panel 4 is further provided with a camera 44, a microphone 45 and a speaker 46. Figure 3 As shown, the camera 44 can capture the user's line of sight and send the captured image to the controller 42. The controller 42 determines whether the user is viewing the photos of relatives displayed on the touch screen 41 based on the user's line of sight captured by the camera. When it is determined that the number of times the user has viewed electronic photos exceeds the second threshold, a video call request is initiated to the relatives through the communication module 43. During the video call, the camera 44 can be used to capture the image of the home user, the microphone 45 can capture the voice of the home user, the touch screen 41 can display the image of the relatives, and the speaker 46 can play the voice of the relatives, so that the home user can talk to his relatives through the smart bed without setting up additional calling equipment, which effectively reduces the learning cost of the home user and the setting cost of the smart device. The setting of the second threshold in this embodiment can be carried out according to the user's own needs, and this embodiment does not limit the specific number of times.

[0032] Furthermore, a stepper motor 11 can be fixed to the bed body 1, and a pressure sensor 31 is provided on the surface of the mattress 3. The stepper motor 11 and pressure sensor 31 are both connected to the controller 42 for communication with the user to wake up the user. Specifically, the user can customize the wake-up time each day. When the wake-up time arrives, the controller 42 detects the pressure value collected by the pressure sensor 31. If the pressure value remains greater than a third threshold value for a preset period of time after the wake-up time, it indicates that the user has not gotten out of bed after the wake-up time. At this time, the controller 42 drives the stepper motor 11 to cause the mattress 3 to shake horizontally and / or vertically within the plane to which the mattress 3 belongs, thereby waking up the user through the shaking of the mattress 3. Especially for children at home who need to wake up at a specific time to go to school, they have low self-control and are prone to staying in bed without being woken by others, resulting in being late for school. The pressure sensor 31 and stepper motor 11 provided in this embodiment can be used to wake the user. This mattress shaking method is more user-friendly, using a specific frequency of shaking without suddenly waking the user. The gentler awakening method is also more conducive to the user getting up. The third threshold value in this embodiment can be set according to the user's needs and is not limited to a specific value in this embodiment.

[0033] In actual implementation, the wake-up time and preset duration can be set independently according to user needs through the touch screen 41, and when the wake-up time arrives, a gradually increasing ring tone can be played through the speaker 46 to wake the user. Alternatively, the wake-up time and preset duration can also be set in the cloud by a remote relative, that is, through the communication module. If the home user does not get up in time or does not get up after shaking the mattress, the controller 42 can also send a reminder message to the remote relative through the communication module 43, so that the remote relative can contact the home user by phone or other means to prevent the home user from staying in bed for too long.

[0034] Furthermore, while the controller 42 drives the stepper motor 11 to rock the mattress, it also monitors changes in pressure in real time. If the user gets out of bed, the pressure gradually decreases. When the controller detects that the pressure is less than or equal to a third threshold, indicating the user has gotten out of bed, the stepper motor 11 can be stopped. While the stepper motor 11 is running, the rocking amplitude and frequency can be gradually increased. If the controller fails to detect that the pressure is less than the third threshold for a certain period of time, the motor can be stopped and a reminder message can be sent directly to a remote relative.

[0035] Home users may get up at night during sleep, and the dark environment at night can easily cause the elderly or children to bump into or fall. In this embodiment, an LED light bar 5 is set on the periphery of the bed body 1. Figure 1As shown, the LED light bar 5 is connected to the controller 42. During the preset sleep time period, if the controller detects that the pressure value is less than or equal to the third threshold, it indicates that the user has woken up at night. At this time, the controller 42 controls the LED light bar to turn on and drives the brightness of the LED light bar 5 to gradually increase, so that the human eye gradually adapts to the light. After the controller 42 re-detects that the pressure value is greater than the third threshold, it proves that the user has returned to bed and continues to sleep. At this time, the LED light bar 5 can be turned off. It should be noted that the preset sleep time period mentioned in this embodiment can be a time period pre-set by the user during which the user should be in a sleep state, such as 11 PM to 5 AM the next day. The preset sleep time period can be personalized according to the user's own situation.

[0036] To further enhance the functionality of the smart bed and allow remote users to promptly monitor the physical condition of the user at home, the smart bed of this embodiment may also include a humidity sensor 32 mounted on the surface of the mattress 3 to detect humidity. If the user at home is an elderly person or child with limited self-care abilities, the humidity sensor can be used to determine whether the user is experiencing incontinence, bedwetting, or other conditions requiring care. Specifically, if the humidity value collected by humidity sensor 32 exceeds a fourth threshold, the controller 42 determines that the user is experiencing incontinence or bedwetting. At this point, the controller 42 sends a care request to a family member via the communication module 43, notifying them of the need for immediate care. Simultaneously, an audible alarm can be issued via the speaker 46 to provide a timely reminder. The fourth threshold value in this embodiment can be set based on the user's needs and is not limited to a specific value.

[0037] The smart bed of this embodiment may further include a heart rate and blood sample collection module and a body temperature detection module (not shown in the figure) arranged on the surface of the mattress 3, and a sound intensity sensor (not shown in the figure) arranged on the headboard 2. The design of the above sensors or modules can realize the collection of data such as the user's heart rate, blood oxygen, body temperature, and snoring during sleep. The touch screen 41 can display the above data such as heart rate, blood oxygen, body temperature, and snoring after sleep. The controller 42 can also upload the above data to the cloud platform through the communication module 43 to analyze the user's sleep quality that night. The cloud platform can also provide sleep suggestions, exercise and diet suggestions according to the sleep quality, and feed back the above analysis and suggestions to the communication module 43, and finally display them on the touch screen 41.

[0038] In some embodiments, the smart bed further includes a heating plate and a temperature sensor (not shown) disposed on the surface of the mattress 3. The controller 42 detects the temperature of the user's sleeping environment via the temperature sensor. During a preset sleep time period, if the temperature value collected by the temperature sensor is less than a fifth threshold, the controller 42 activates the heating plate to heat the mattress, thereby ensuring that the user sleeps in an environment with a suitable temperature. The fifth threshold value in this embodiment can be set based on the user's needs and is not limited to a specific value in this embodiment.

[0039] It should be noted that the aforementioned sensors, data acquisition modules, and other components enter standby mode when the user is not within the bed's range (i.e., not sitting or lying on the bed), retaining only the touchscreen display of the time and electronic photos. Furthermore, the smart bed can further coordinate with other smart devices in the house to adjust the user's sleeping environment. For example, if the temperature sensor detects a high temperature, it can activate the indoor fan; if the humidity sensor detects a low humidity, it can activate the indoor humidifier; and when the wake-up time arrives, the smart speaker can play music to wake the user and control the opening of the smart curtains.

[0040] In the actual implementation process, the form of the control panel 2 is set according to the shape and size of the headboard 2. Its touch screen can be an LCD with touch function. The controller can adopt the STM32F103C8T6 model microcontroller, and the communication module adopts the ESP8266 model WiFi module. Among them, the ESP8266 model WiFi module is a UART-WIFI transparent transmission module chip based on the wireless communication protocol. It has three working modes: Staion, AP, and Staion+AP. In AP mode, ESP8266 can access wireless services and thus connect to the cloud. The STM32F103C8T6 microcontroller sends AT commands to the ESP8266 module through serial port communication to complete its control, such as mode selection, joining WIFI, establishing TCP / UDP connection, etc. Figure 4 The figure shows a schematic diagram of the circuit structure of the ESP8266 WiFi module in this embodiment.

[0041] In addition, in this embodiment, the stepper motor can be an SG90 model servo, and its control signal is a pulse width modulation (PWM) signal with a period of 20ms, wherein the pulse width varies linearly from 0.5ms to 2.5ms, and the position of the corresponding steering wheel is 0-180 degrees. In other words, if a certain pulse width is provided to it, its output shaft will remain at a corresponding angle, no matter how the external torque changes, until it is provided with a pulse signal of another width, it will change the output angle to the new corresponding position. There is a reference circuit inside the servo, which generates a reference signal with a period of 20ms and a width of 1.5ms. There is a comparator that compares the external signal with the reference signal to determine the direction and size, thereby generating a rotation signal for the motor. The pressure sensor uses the HX711 model pressure sensor, and its circuit structure diagram is shown as follows. Figure 5 As shown in the figure, the HX711 is a high-precision, low-noise analog front-end chip commonly used in load cell and load detail measurement applications. It has a built-in amplifier and ADC (analog-to-digital converter) that can convert the analog signal of the load cell into a digital signal. A load cell, also known as a load cell, measures weight (or more accurately, directional force) by converting it into an electrical output, usually through a combination of a spring element and a strain gauge. A strain gauge load cell consists of a solid metal body (or "spring element") to which a strain gauge is fixed. When a load is applied, the body of the load cell slightly deforms and deflects.

[0042] In addition, the temperature sensor and humidity sensor can be implemented using the DHT11 temperature and humidity sensor. The corresponding circuit structure diagram is as follows: Figure 6 As shown; the body temperature sensor can be realized by the DS18B20 sensor, and its corresponding circuit structure diagram is as follows Figure 7 As shown; the sound intensity sensor can be realized by the ky-038 high-sensitivity sound sensor module, and its corresponding circuit structure diagram is as follows Figure 8 As shown; the heart rate and blood oxygen collection module can be realized through the MAX30102 pulse oximeter and heart rate monitor biosensor module. The corresponding circuit structure diagram is shown in Figure 9 shown.

[0043] This embodiment intelligently improves essential home bedding. It uses photos of family members displayed on the touchscreen display of the control panel integrated into the headboard to monitor the user's needs for emotional interaction with family members. The communication module then sends messages, allowing distant relatives to promptly learn of the user's emotional interaction needs. This functionality is achieved solely through the smart bed, without the need for additional smart home devices. This improves the user's quality of life and allows distant relatives to better understand the user. Further integration with various sensors allows monitoring of the user's sleep status and sleeping environment, helping to improve the user's lifestyle and sleep quality. It also makes the smart bed more intelligent and entertaining, enhancing the user's quality of life.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein.
