Description

Technical Field

[0001] The present application relates to the field of sleep technology, and in particular to a baby crib sleep system. Background Art

[0002] The main limitation of existing crib designs is that they tend to focus only on the most basic safety needs, which is to prevent babies from rolling out of the bed while sleeping through fixed guardrails around the four sides. This design fails to fully consider the complexity and special needs of infant sleep, especially the significant difference from adult sleep patterns. Infants have shorter sleep cycles than adults and are more susceptible to external stimuli, such as temperature changes, light, noise, etc. These factors may cause babies to wake up and start crying at the end of their sleep cycle. Traditional cribs lack the ability to monitor and respond to these changes, which means that parents may not immediately notice their baby's discomfort or needs, causing the baby to feel anxious and uneasy while waiting to be cared for.

[0003] Secondly, when babies transition from one sleep cycle to the next, they may need additional comfort and soothing to fall back to sleep. Existing cribs do not have sleep-inducing features, such as playing soothing music, simulating heartbeats, or providing gentle rocking, which are effective ways to help babies relax and fall back to sleep. Therefore, during this critical period, babies may experience long periods of wakefulness, affecting their overall sleep quality and growth and development.

[0004] Modern families are increasingly relying on smart devices to improve their quality of life. In contrast, traditional cribs lag behind in this regard, lacking integrated smart technologies such as temperature sensing, humidity control, and voice recognition, which can monitor the baby's physiological state, warn of possible discomfort in advance, and even take proactive measures such as adjusting the room temperature and playing soothing music to improve the baby's sleeping environment.

[0005] To sum up, the functional limitations of existing cribs are not only reflected in the lack of basic environmental adaptability and improvement of infant comfort, but also in the failure to make full use of modern technology to meet the specific sleep needs of infants, thereby providing effective assistance to parents and reducing the pressure of parenting.

[0041] The following describes the embodiments of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0042] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of this application.

[0043] In the existing technology, the functional limitations of baby cribs are not only reflected in the lack of basic environmental adaptability and improvement of baby comfort, but also in the failure to fully utilize modern technology to meet the specific sleep needs of infants, thereby providing effective assistance to parents and reducing the pressure of parenting.

[0044] Therefore, in order to solve the above-mentioned technical problems, the embodiment of the present application proposes a baby crib sleep system. Since traditional baby cribs are relatively rigid and do not have the function of coaxing babies to sleep, they can only be manually intervened. The baby crib sleep system realizes the adjustable shaking of the baby crib to help babies sleep, which not only improves the quality of sleep, but also saves parents' manpower and time. Ordinary baby cribs do not have the function of detecting the temperature and humidity of the baby's body. The present application uses a temperature and humidity detection device to collect data to accurately detect the temperature and humidity conditions in real time, and displays the real-time temperature and humidity on the display screen to facilitate parents to make appropriate responses. It also plays music through Bluetooth, and is combined with a servo to shake the baby crib, which greatly improves the efficiency of coaxing babies to sleep and care for them, and also saves parents' time to accompany their babies. The display screen displays a function menu to facilitate parents to adjust the shaking of the baby crib, the content of the music playback function, etc., which will be described in detail below.

[0045] Please refer to Figure 1 , Figure 1 A baby crib sleeping system proposed in an embodiment of the present application is shown, the system includes a main control module, a power module, a music playing module connected to an external Bluetooth device or inserted into an external storage device, a detection module, a sound collection module, a steering gear module, a communication module and a display module;

[0046] The power output end of the power module is connected to the power input end of the main control module, the control input end of the music playing module is connected to the control output end of the main control module, the data input and output end of the detection module is connected to the data input and output end of the main control module, the data output end of the sound collection module is linked to the data input end of the main control module, the control input end of the steering gear module is connected to the control output end of the main control module, the data output end of the main control module is connected to the data input end of the communication module, the data output end of the communication module is connected to the remote guardian terminal, and the data output end of the main control module is connected to the data input end of the display module;

[0047] A power module, used to supply power to the system;

[0048] Music playing module, used for playing music;

[0049] A detection module, used to detect the baby's condition and the real-time temperature and humidity around the crib in real time;

[0050] The sound collection module is used to collect real-time crying sounds and send them to the main control module;

[0051] Servo module, used to rock the crib;

[0052] A communication module is used to realize wireless data transmission and upload data to a remote guardian terminal;

[0053] Display module, used to display function menu and crib parameters;

[0054] The main control module is used to upload the real-time temperature and humidity to the terminal and / or display screen, drive the servo module to rotate according to the real-time crying sound and upload it to the terminal.

[0055] In the specific implementation, the signal flow relationship is as follows: the current flow direction is TYPE-C input, and the TP4056 module steps down the voltage to power the battery and the system at the same time. The TPS6088 module boosts 9V, one part is supplied to the power amplifier NS4110B module, and the other part is supplied to the TPS5430 module, and the voltage is stepped down to 5V to power the servo and USB. The RT9013 module steps down 3.3V to power the ESP32-53 module and the STM32 module. The camera is connected to the ESP32 module, the ESP32 module serial port is connected to the STM32, the STM32 module is connected to the servo and the SHT30 temperature and humidity sensor, and the Bluetooth is connected to the AC9625 module and then to the NS4110B module.

[0056] The main control module uses the STM32 module. In specific implementation, the main control module can be used Figure 2 The circuit shown, Figure 2An interface diagram of the main control module STM32 proposed in an embodiment of the present application is shown, which shows an STM32F401CCU6 microcontroller (MCU) and the power supply and ground connections associated therewith. In the figure: VBAT is the battery voltage input port for powering the system. VDD and VSS are the power and ground pins, VDD represents the positive power supply, and VSS represents the ground. VDDB / VREF+ and VSSB / VREF- are digital power and reference ground, respectively, for internal analog circuits and reference voltages. C1 is a capacitor, which is connected between VDD and GND and is used as a decoupling capacitor to filter out power supply noise and ensure a stable power supply.

[0057] In order to stabilize the working environment of the microcontroller, proper power and ground connections are provided, and decoupling capacitors are used to reduce interference on the power line. Such a configuration helps ensure the normal operation of the microcontroller and reduces potential problems caused by power supply fluctuations.

[0058] The communication module uses the ESP32 module for wireless data transmission. It is a low-power Wi-Fi + Bluetooth dual-mode SoC chip that supports serial communication protocols. ESP32_S3 is used as a microcontroller to exchange data with another device or microcontroller through its serial communication interface. In this setting, ESP32_S3 can act as the main processor, receive data from the serial port, and then send the data wirelessly through its built-in Wi-Fi or Bluetooth module; conversely, ESP32_S3 can also receive wireless data and then transmit the data to other devices through the serial port.

[0059] The detection module includes a temperature and humidity sensor and a camera arranged at the side of the crib;

[0060] A camera installed at the side of the crib is used to monitor the baby's condition in real time;

[0061] Temperature and humidity sensor, used to detect the real-time temperature and humidity around the crib.

[0062] In a possible implementation, the camera uses an ov2640 module, and the ov2640 module is connected to the main control module via parallel port communication.

[0063] Please refer to Figure 3 , Figure 3 The interface diagram of the camera ov2640 proposed in the embodiment of the present application is shown, connecting the OV2640 camera module with the microcontroller ESP32. OV2640 is a CMOS image sensor, and ESP32 is a microcontroller with Wi-Fi and Bluetooth functions, which is specifically used for:

[0064] 1. Power supply: OV2640 requires a +3.3V power supply to work, so you need to connect the power pin (VDD) of OV2640 to the +3.3V power pin of ESP32.

[0065] 2. Ground connection: To ensure the correct transmission of the signal, the GND pin of OV2640 needs to be connected to the GND pin of ESP32.

[0066] 3. Data transmission: OV2640 transmits data to ESP32 through a parallel interface. The parallel interface allows data to be transmitted on multiple pins simultaneously, thereby increasing the data transmission speed.

[0067] The temperature and humidity sensor uses the sht30 module, and the temperature and humidity data output end of the sht30 module is connected to the data input of the main control module through the IIC protocol transmission line.

[0068] Please refer to Figure 4 , Figure 4 The interface diagram of the temperature and humidity sensor SHT30 proposed in the embodiment of the present application is shown, which includes a SHT30 temperature and humidity sensor. This sensor is designed to be used through I 2 C communication protocol to an STM32 microcontroller.

[0069] In order for the SHT30 sensor to communicate correctly with the STM32 microcontroller:

[0070] 1. Connect the SDA and SCL pins to the corresponding IIC interface pins of the STM32 microcontroller respectively.

[0071] 2. Provide appropriate power supply voltage (VDD) to the sensor and ensure that the GND pin is grounded.

[0072] 3. Set the ADDR pin as needed to determine the sensor's unique address on the IIC bus.

[0073] 4. Make sure the ALERT pin is properly connected and configured to receive the alert signal when necessary.

[0074] 5. Realize the hardware reset of the sensor by pulling down the nRESET pin.

[0075] The interface of the display module is SPI, which is connected to the ESP32 module through the SPI interface.

[0076] Please refer to Figure 5 , Figure 5The interface diagram of the high-definition full-color screen FPC1 proposed in the embodiment of the present application is shown. The display screen proposed in the embodiment of the present application adopts a system of a 1.47-inch IPS high-definition full-color screen (FPC1), which communicates via SPI (serial peripheral interface). This design enables the main control device (such as a microcontroller or a single-chip microcomputer) to communicate with the 1.47-inch LCD screen via the SPI bus, and can independently control the display content of the screen and the brightness of the backlight.

[0077] The power module includes a TP4056 linear charging chip module, and a VCC terminal of the power chip TP4056 module is connected to a power input terminal of the main control module.

[0078] Please refer to Figure 6 , Figure 6 The interface diagram of the TP4056 linear charging chip proposed in the embodiment of the present application is shown, which shows the use of the TP4056 linear charging chip to charge a single lithium-ion battery. The TP4056 is a linear charging management integrated circuit designed for single-cell lithium-ion batteries, with constant current / constant voltage characteristics to ensure a safe and efficient charging process. In addition, it also provides a variety of protection functions, including short circuit protection, over-temperature protection, and overcharge protection.

[0079] The power supply part uses a type-c interface to charge a single lithium battery.

[0080] In a possible implementation, the power module includes a TPS61088 boost module, and the input end of the TPS61088 boost module is connected to the output end of the power chip TP4056 module for boosting the battery.

[0081] Figure 7 The interface diagram of the boost module TPS61088 proposed in the embodiment of the present application is shown, which shows a boost converter design using the TPS61088 chip. The TPS61088 is a high-efficiency switch-mode power management integrated circuit used to boost a low voltage input (such as a battery) to a higher output voltage to power the system.

[0082] The TPS61088 converts the lower voltage provided by the battery into a higher voltage of 9V, which is then supplied to the system. This design is suitable for application scenarios that require higher voltage but have limited available power, such as portable devices or IoT devices.

[0083] In a possible implementation, the system further includes an audio amplifier module for decoding and playing music and reading files from a memory card and a USB flash drive;

[0084] The audio power amplifier module includes a Bluetooth audio signal receiving module and a power amplifier module. The Bluetooth audio signal receiving module adopts an AC6925 module, and the power amplifier module adopts an NS4110B module.

[0085] Audio decoding and playback, as well as reading files from memory cards and USB flash drives, usually involve the coordinated work of multiple components. The AC6925 and NS4110B mentioned here are chips for audio decoding and power amplification (amplifier) ​​respectively.

[0086] AC6925 is an audio decoding chip that converts digital audio signals into analog audio signals. Digital audio signals are usually stored in memory cards or USB flash drives, and these signals need to be decoded before they can be played through speakers or headphones. Chips such as AC6925 can process multiple audio formats, such as MP3, WAV, AAC, etc., and convert them into analog signals for subsequent power amplification.

[0087] The NS4110B is used to boost the power of audio signals so that they are powerful enough to drive speakers or headphones. After the audio signals are decoded and converted into analog signals, their driving capabilities are often weak and not enough to directly drive the speakers to produce sufficient volume. The role of power amplifier chips such as the NS4110B is to receive the audio signal from the decoding chip and increase its power to ensure that the sound is clear, loud and undistorted. As for reading files from memory cards and USB flash drives, this usually requires a microcontroller or processor to control the read and write operations. The microcontroller reads the data on the storage device and then sends the audio file to the AC6925 for decoding. This process may also include functions such as file system management and error checking to ensure the correctness and integrity of the data.

[0088] AC6925 is responsible for decoding audio files, while NS4110B is responsible for amplifying the decoded audio signals and finally playing them through speakers or headphones. At the same time, the system's main control unit is responsible for reading audio files on the memory card or USB flash drive and sending them to AC6925 for processing.

[0089] Figure 8The structural schematic diagram of another crib sleep system proposed in the embodiment of the present application is shown, which combines the multiple modules and module models described above, and integrates power charging, wireless transmission, screen display, environmental monitoring, camera, microphone, Bluetooth audio, crib cradle and other functions, connects to the power supply through the Type-C interface, and uses the TPS61088 linear charging chip for power supply. The main control chip uses STM32, which is responsible for coordinating the work of the entire system. In the music playback module, decoders such as AC6925 and NS4110B are used to process audio signals, and wireless music playback can be achieved through the mobile phone Bluetooth connection. In the camera and temperature and humidity detection module, the SHT30 sensor is used to monitor the ambient temperature and humidity in real time; the ov2640 camera is used for image acquisition. In addition, the microphone can collect the baby's crying and drive the servo to rotate to start the coaxing function. ESP32, as an auxiliary control unit, participates in the communication and data transmission of multiple subsystems. In the Internet upload part, the monitor can view the real-time monitoring screen and receive remote reminder notifications through the mobile phone.

[0090] The battery is powered by TP4056, and the TPS61088 is boosted to 9V. One part is supplied to the power amplifier NS4110B, and the other part is supplied to TPS5430. The voltage is stepped down to 5V to power the servo and USB. RT9013 is used to step down 3.3V to power ESP32-S3 and STM32. The camera is connected to ESP32, the ESP32 serial port is connected to STM32, and the STM32 is connected to the servo and SHT30 temperature and humidity sensor. Bluetooth is connected to AC9625 and then to NS4110B.

[0091] The system collects environmental information and displays it on the terminal screen, provides a smart furniture interface, and can also upload data to the Internet through ESP32 for users to view in real time. The microphone can detect and process the baby's crying, rock the crib to coax the baby to sleep, and remind the parents.

[0092] The camera can be used to monitor the situation in the crib in real time. When parents need to play lullabies or bedtime stories, they can insert a USB flash drive or TF card to play them, or connect the phone to Bluetooth to play the desired audio. All data of the crib can be viewed remotely through the Internet.

This application integrates multiple functions, which is convenient for parents while also providing protection for the safety and life of the baby.

[0094] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0096] Second, the music playback module plays a great role in coaxing babies to sleep. The key point is the sound quality of the music. The clarity of the music and the overall listening experience are important factors. The second is the power consumption of the music. For a baby bed, low power consumption is convenient for users. The third is convenience. Parents can connect and play the required music through Bluetooth, which is easy to operate.
