Description

A multifunctional baby cradle

technical field

The utility model belongs to the field of electronic technology, in particular to a multifunctional baby cradle.

Background technique

In the traditional way of raising babies, Chinese people hold the baby in their arms and gently pat and shake them or use human power to push the cradle to make the baby quiet down and sleep, but this is not conducive to the development and growth of the baby. Traditional baby cradles in various parts of China include hanging baskets, cradles, and cradles. It is not only time-consuming and labor-intensive to use, but also increases the labor burden. It also produces loud noises, making it difficult for babies to sleep deeply. At the same time, the improper way of traditional baby care will cause the baby's brain to be in a state of weightlessness and congestion, which seriously affects the baby's brain development and bone growth. For infants and toddlers, sleeping, like breastfeeding, is a top priority during their growth. A suitable crib can not only ensure the healthy growth of the baby, but also greatly reduce the burden on the parents, so that the parents do not have to worry about taking care of the baby all night, so as to ensure that both adults and children have a higher quality of life. It frees parents from the heavy labor of caring for babies.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, a multifunctional baby cradle includes a cradle frame, a power supply module 1, a temperature and humidity detection module 2, a pressure sensor module 3, a sound detection module 4, and a data acquisition and processing system 5 powered by the power supply module, an infrared Heat radiation module 6, motor drive module 7, display module 8, music prompt playing module 9 and WeChat interconnection module 10. The data acquisition and processing system 5 takes the STM32F407 series microprocessor 5-1 of STMicroelectronics as the core, and processes and analyzes the data collected by the temperature and humidity detection module, infrared heat radiation module, pressure sensor module and sound detection module, Then send instructions to the music prompt playback module, WeChat interconnection module, motor module and display module to realize the display of the screen and the control of the swing range of the cradle frame, as well as the function of instant notification to the baby guardian when an accident occurs on the baby. User instructions are transmitted to the data acquisition and processing system through the display module; in addition, the data acquisition and processing system includes an SD card reading and writing module 5-2, and the baby guardian can store the baby's favorite music in the SD card reading and writing module, and the music prompts the playback module Play to soothe a crying baby.

The temperature and humidity detection module 2 takes the DHT11 digital temperature and humidity sensor as the core. The DHT11 digital temperature and humidity sensor has the advantages of ultra-fast response and strong anti-interference ability. The temperature and humidity detection module transmits data with the data acquisition and processing system in a single-bus transmission mode. The measured humidity range is 20-90% RH, and the humidity resolution is 1% RH. Placing the temperature and humidity detection module in the baby's mattress can effectively detect the baby's bedwetting in real time.

The infrared heat radiation module 6 takes an infrared thermopile as the core, and the infrared thermopile contains a digital filter and a digital processing chip, and the measured temperature error can be controlled within ±0.2°C. After the infrared heat radiation module measures the infrared heat radiation of the human body through the infrared sensor, the converted temperature value is transmitted to the data acquisition and processing system in hexadecimal form.

The motor drive module 7 takes the chip L298N as the core. The user operates the touch screen in the display module, changes the input duty cycle of the chip L298N to change the steering and rotation speed of the DC motor 7-1, thereby changing the swing range and speed of the cradle frame.

The pressure sensor module 3 takes the piezoresistor as the core, cooperates with the peripheral signal conditioning circuit, so that the output voltage of the pressure sensor module changes with the change of the pressure received by the piezoresistor. If the baby's sleep quality is not good, he will toss and turn on the bed, and the output voltage value on the varistor will fluctuate in a series. The data acquisition and processing system collects the change of the output voltage value through the A/D converter 5-3, and makes a judgment.

The sound detection module 4 takes the microphone as the core, converts the sound vibration signal into an electrical signal, and then amplifies and shapes the electrical signal to obtain a square wave with a certain frequency.

The power supply module 1 is based on a switching power supply chip and a linear voltage regulator chip. The input of the power module is a 12V DC power supply, which outputs a 5V DC power supply after being stepped down by a switching power supply chip; the 5V DC power supply then outputs 3.3V and 2.5V DC power supplies through a linear voltage regulator chip. The switching power supply chip steps down the 12V power supply to 5V, and uses the BUCK topology to improve the power supply efficiency.

The WeChat interconnection module will be further described in conjunction with accompanying drawing 2 below.

Wechat interconnection module 10 is made up of mobile phone 10-1, Wechat server 10-2 and hardware equipment server 10-3, mainly realizes two functions, one is to send messages to Wechat on the mobile phone when the baby is crying or wetting the bed and other events Official account, the second is to control the swing of the cradle frame and music playback through the WeChat official account on the mobile phone.

When the baby is crying, the sound detection module will detect the crying sound of the baby. The microprocessor sends a message to the mobile phone through Bluetooth. The message is forwarded by the WeChat server and then reaches the device server. The device server judges and processes the event, and generates An instruction, after being forwarded by the WeChat server, reaches the WeChat official account on the mobile phone, so that the message of the baby crying is displayed on the WeChat official account on the mobile phone.

After the WeChat official account on the mobile phone presses the button to control music playback, the mobile phone will send a message to the WeChat server, which will be forwarded by the WeChat server to the device server, and the device server will process the message. After completion, a command will be generated and sent to the WeChat server.
