基于单片机的婴儿车系统设计 PAGE 23 摘 要 在当今社会快速发展和科技发达的背景下，智能家居设备已经走进了很多家庭。作为新手父母在对婴儿进行照顾时必然会因为经验不足的原因从而出现问题，尤其是户外出行时。因此，智能婴儿车在此背景下应运而生。 本文提出了一种基于单片机的智能婴儿车的系统方案，目的为解决婴儿出行时让婴儿处于最舒适环境中。方案采用STM32单片机作为系统的主控芯片，通过DHT11温湿度传感器来实现对婴儿车内的温度和湿度数据的检测，并且根据设定的阈值判断是否需要开风扇。声音检测传感器用来对环境噪音进行检测，在超过阈值范围后会通过播放音乐环节婴儿情绪。同时系统还配备了无线传输模块使得通过手机就可以实时观察婴儿车内的各种环境参数。也为了方便更直观快捷的观察，系统还加入了LCD1602液晶显示模块用来显示。 通过软硬件设计对方案进行实现，然后对设计出的硬件系统进行功能测试，分别对系统各模块功能进行测试，从测试结果可以看出，本文所设计的基于单片机的婴儿车系统符合设计要求，在满足设计的同时，还具有成本低廉、功能齐全、结构简单等优点，具有较好的社会实际使用价值。 关键词：智能设备；婴儿车；温湿度监测；噪音检测 Abstract In the context of rapid social development and advanced science and technology, smart home devices have entered many families. New parents are bound to have problems with baby care due to their inexperience, especially when traveling outdoors. Therefore, the intelligent baby carriage came into being in this context. This paper puts forward a system scheme of intelligent baby carriage based on single chip microcomputer. The purpose is to let the baby be in the most comfortable environment when the baby travels. The scheme uses STM32 microcontroller as the main control chip of the system, and detects the temperature and humidity data in the stroller through DHT11 temperature and humidity sensor, and determines whether the fan needs to be turned on according to the set threshold. Sound sensors are used to detect ambient noise and play music to measure the babys mood when it exceeds a threshold range. The system is also equipped with a wireless transmission module that allows real-time observation of various environmental parameters in the stroller via mobile phone. In order to facilitate more intuitive and fast observation, the system also added LCD1602 LCD display module for display. By hardware and software design scheme for implementation, and then to design the hardware system for functional testing, testing system has the function of each module respectively, can be seen from the test results, this paper designed the pram system based on single chi
