设计简介：
项目编号：mcuclub-dz-034
项目名：婴儿床
单片机：STM32F103C8T6
功能简介：
1、通过防水式温度传感器检测婴儿被窝内温度，当温度过高或过低，通过蓝牙发送“温度异常”
2、通过声音传感器检测声音大小，当声音大于设置最大值，则自动播放音乐，启动步进电机来回摇晃婴儿床，通过蓝牙发送“婴儿哭闹”
3、通过液体湿度传感器检测湿度，当湿度大于设置最大值，为婴儿尿床，通过蓝牙发送“婴儿尿床”
4、通过MPU6050检测婴儿是否撞击到床上，如果撞击，通过蓝牙发送“婴儿遭受撞击”
5、通过按键设置各阈值
6、通过显示屏显示测量值

基于STM32单片机的婴儿床设计
摘要
婴儿的体温调节功能尚不完善,因此需要采取一定的措施保持婴儿周围环境处于婴儿适宜的环境之中，当前婴儿主要放置在婴儿床中，因此对婴儿床环境控制很有闭药。传统的婴儿床缺点很多:缺乏哭泣检测、缺少尿床监测、缺乏自动控温控湿、缺乏安全状态检测。考虑婴儿床受到的温湿度影响较大，婴儿尿床、婴儿床的安全状态及婴儿睡醒是否哭泣等问题，进行全方面的考虑和设计；采用软硬件配合进行设计，硬件选用STM32单片机作为主控芯片，DHT11温湿度传感器对温湿度进行检测，液体湿度传感器对是否尿床进行检测，MPU6060传感器婴儿是否哭泣进行检测，当婴儿哭泣时，系统可以自动播放音乐，从而达到对婴儿的全方面检测，在检测到婴儿发生撞击等意外情况时，蓝牙模块JDY-31能够及时把信息传递给家长。完成监护人对婴儿所处环境的及时了解。
该监护系统在硬件和软件方面都做了改进，还添加音乐播放模块，尿床监测模块。实现了及时监护的系统功能。

Abstract
The baby’s thermoregulation function is not perfect, so it is necessary to take certain measures to keep the baby’s surrounding environment in a suitable environment. At present, babies are mainly placed in cribs, so it is very effective to control the crib environment. Traditional cribs have many shortcomings: lack of crying detection, lack of bed-wetting monitoring, lack of automatic temperature control and humidity control, and lack of safety status detection. Considering that the crib is greatly affected by the temperature and humidity, the baby wets the bed, the safe state of the crib and whether the baby cries when he wakes up, etc., all aspects of consideration and design are carried out; The hardware and software are designed together. The hardware adopts STM32 MCU as the main control chip, DHT11 temperature and humidity sensor detects the temperature and humidity, liquid humidity sensor detects whether the baby wets the bed, MPU6060 detects whether the baby cries, and the system can automatically play music when the baby cries, so as to achieve all-round detection of the baby. When unexpected situations such as baby impact are detected, Bluetooth module JDY-31 can timely transmit information to parents. Complete the guardian’s timely understanding of the baby’s environment.
The monitoring system has been improved in hardware and software, and a music playing module and a bed-wetting monitoring module have been added. The system function of timely monitoring is realized.
