人类诞生以来，儿童的保育在家庭生活中扮演着重要的角色，婴儿床等育儿工具的发展，在一定的程度上减轻了父母的育儿压力，因此育儿设备的发展备受关注。当前，婴儿床结构简单、功能单一，以致于家长在护理工作中出现操作不方便、使用周期短等问题。婴儿床作为婴儿休息的主要工具，对婴儿的物质认知和智力开发起到关键作用，因此，设计一款智能婴儿床意义重大。本设计基于STM32单片机，使用声贝传感器监测婴儿是否处于哭泣状态，如果检测到婴儿哭泣，通过播放器播放音乐哄孩子，并通过蓝牙模块发送婴儿哭泣信息给监护人；通过温湿度传感器检测婴儿所处环境温湿度，如果温湿度异常，进行相应的除湿加热操作，使环境温湿度处于适于婴儿成长的范围之内；通过雨水检测传感器检测婴儿是否尿床，如果发现婴儿尿床，通过蓝牙发送尿床信息提醒监护人换尿布；通过按键设置温湿度上下限，通过OLED显示测量值，通过蓝牙，手机端可实时获取数据，将婴儿床周围情况通过传感器进行检测和实时做出对应的处理，从而使得婴儿的环境处于适宜的环境，婴儿的情绪得到安抚，营造一个有利于儿童健康成长的生活环境。本设计的婴儿床主要以智能化、多功能为发展方向，通过改变婴儿床的功能来满足广大使用者的使用需求，为婴儿提高舒适的成长环境。

[Abstract] Since the birth of humanity, child care has played an important role in family life. The development of childcare tools such as baby beds has to some extent alleviated parental pressure, so the development of childcare equipment has received much attention. Currently, the structure of the baby bed is simple and its function is single, leading to problems such as inconvenient operation and short usage cycle for parents in nursing work. As the main tool for infants to rest, baby beds play a key role in their material cognition and intellectual development. Therefore, designing an intelligent baby bed is of great significance. This design is based on the STM32 microcontroller, using a sound sensor to monitor whether the baby is crying. If it is detected that the baby is crying, the player plays music to coax the child, and sends the baby’s crying information to the guardian through the Bluetooth module; Detect the temperature and humidity of the infant’s environment through temperature and humidity sensors. If the temperature and humidity are abnormal, perform corresponding dehumidification and heating operations to keep the ambient temperature and humidity within the range suitable for the growth of the infant; Detect whether the baby wets the bed through the rain detection sensor. If the baby wets the bed, send a wetness message through Bluetooth to remind the guardian to change the diaper; Set the upper and lower limits of temperature and humidity through buttons, display the measured values through OLED, and use Bluetooth to obtain data in real time on the mobile phone. The environment around the baby bed can be detected through sensors and corresponding processing can be made in real time, so as to make the baby’s environment in a suitable environment, soothe the baby’s emotions, and create a living environment conducive to the healthy growth of children. The design of the baby bed is mainly oriented towards intelligent and multifunctional development. By changing the functions of the baby bed, it can meet the needs of users and improve a comfortable growth environment for infants.
