摘 要
婴儿的体温调节功能尚不完善,传统的婴儿床存在以下个缺点:家人听过哭声后才进行安抚，缺少哭泣检测;缺少尿床监测;不能实现自动控温控湿；不能检测婴儿床是否受到撞击。
此次设计考虑到婴儿在婴儿床中受到的温湿度影响较大，婴儿尿床、婴儿床是否受到撞击及其婴儿在醒来时容易哭泣等问题进行考虑和设计；此次设计采用硬件和软件配合进行设计，硬件采用STM32单片机作为主控芯片，采用温湿度检测模块DHT11对婴儿床内温湿度进行检测，采用雨滴检测模块，检测婴儿是否尿床，通过MPU6060对婴儿床是否受到撞击进行检测，通过声音检测模块可以检测当前婴儿是否哭泣，当检测到婴儿哭泣时，自动播放音乐，实现对此次设计婴儿床的监护，当检测到婴儿哭泣火灾受到撞击时通过蓝牙模块JDY-31将信息传输到家人的手机上。然后通过keil5对程序的编程，进行主程序、数据采集功能子程序、按键子程序、显示子程序、蓝牙通信子程序进行撰写和调试，然后通过软件和硬件的配合进行调试，此次设计最终调试可以实现对婴儿床的准确检测，使得家中监护者可以实时火灾远距离对家中婴儿床的检测。使得婴儿环境得到很大的改善，监护人也可以对婴儿的情况进行实时处理。
此次设计监护系统在硬件和软件方面都对传统的婴儿床做了改进.在系统中增加了尿床监测模块,音乐播放等.控制方案更加科学合理,性能稳定,功能完善,成本低廉,实际效果理想.

Abstract
The thermoregulation function of infants is not perfect. One of the most important measures for effective nursing of infants, especially infants with very low body weight, is to maintain an optimal environment. A large amount of modern biomedical data shows that a warm environment can reduce the incidence and mortality of infants caused by direct or indirect cold stress response, thus effectively guaranteeing the survival rate of newborns. The crib can create a comfortable environment with clean air and suitable temperature and humidity for the newborn, so as to avoid the infection of the baby to enhance its body resistance and ensure the growth of the baby. Traditional cribs have the following drawbacks: family members listen to crying before calming down, lack of crying detection; Lack of bed-wetting monitoring; ; Can not realize automatic temperature and humidity control; The crib cannot be tested for impact.
In view of the traditional control equipment of the poor ability of automatic control is improved, the baby bed temperature and humidity control system as the carrier to complete the data acquisition and signal processing, core USES STM32 MCU, and comply with, drive heating, cooling, humidification, dehumidification, music playback, shaking table for processing, with liquid crystal display module as a display unit, complete the temperature and humidity, the baby is No crying detection module, whether the baby is bed-wetting detection module, whether the baby is hit detection module and other signals are sampled to realize the monitoring of the designed crib.
The monitoring system is an improvement on the traditional crib in both hardware and software. Bed-wetting monitoring module and music playing are added in the system. The control scheme is more scientific and reasonable, stable performance, perfect function, low cost and ideal practical effect..
