This design is based on embedded technology intelligent crib, the system to STM32F767IGT6 single chip microcomputer as the control core, the use of sensor acquisition technology and STM32 main control chip to build information acquisition system, through the temperature and humidity sensors and other communication modules, to achieve the mobile terminal remote monitoring baby status function; Play music function; Automatic shaker sleep function; Call alarm function. Many experiments show that the system is running in good condition, solves the problem of time-consuming and laborious when the guardian takes care of the baby, and liberates the parents' hands to a certain extent. This work can achieve the following functions: (1) Real-time monitoring of baby's condition: the baby's condition can be observed in real time through WIFI and camera on the mobile phone; All kinds of information of the baby can be observed on the display screen of the mobile phone and the system, such as the air quality around the baby, the temperature and humidity of the mattress, whether to wet the bed and cry, etc. (2) Data transmission and visualization of baby's condition: the baby's information is displayed on the mobile phone and system display screen, which is convenient for parents to observe and process in time. (3) Automatic call for abnormal baby conditions: When the system detects an abnormal baby condition, it will display on the system display and call the parents through the SIM900A. (4) Automatically coax the baby to sleep: when it is necessary to coax the baby to sleep, the sleeping mode can be started through the system display screen and the mobile phone APP, and the system will shake the bed body according to the gear to coax the baby to sleep. (5) Real-time monitoring of the baby's surrounding environment: The air quality sensor is used to monitor the air quality around the baby in real time to ensure a good breathing environment for the baby. At the same time, the environmental quality information is transmitted to the mobile phone APP. (6) music playback: you can play children's songs on the mobile phone and the system display screen to coax the baby to sleep.
