婴儿看护是每个家长应该承担的责任，但在社会高速发展的今天，大多数家长需要兼顾家庭和工作的，传统的看护方式不再满足各个家庭的需求，“三胎”政策的开放更是加剧了婴儿看护的压力。为了能减轻家长的负担以及降低看护风险，论文提出了一种婴儿监护仪的系统来辅助传统看护。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；本系统采用硬件和软件相结合的方式进行设计，硬件采用STC89C52单片机作为主控芯片，采用液位检测模块YL-AO对婴儿是否尿床进行检测，通过SY声音监测模块检测当前婴儿是否哭泣，当检测到婴儿哭泣时，则进行声光报警提醒家长。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、按键子程序等进行编写和调试，最后通过软硬件配合实物进行调试，调试结果显示，该系统可以实现对婴儿床的准确检测，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。基于单片机控制技术和传感器检测技术，通过软硬件结合，设计一款智能婴儿监护仪装置，通过实物测试，该装置能够在无人条件下自动完成婴儿的监护操作，解决了婴儿监护困难的问题，该婴儿监护仪经过改进、完善、具有一定的实用价值和推广前景。

Infant care is the responsibility of every parent. However, with the rapid development of society today, most parents need to balance family and work, and the traditional way of care can no longer meet the needs of each family. The opening of the “three-child” policy has intensified the pressure of infant care. In order to relieve the burden of parents and reduce the risk of nursing, this paper proposes a system of infant monitor to assist traditional nursing.The design takes into account the baby in the crib affected by temperature and humidity, baby wet bed, crib impact and the baby easy to cry when waking up to consider and design; The system uses a combination of hardware and software design, the hardware uses STC89C52 single chip microcomputer as the main control chip, the liquid level detection module YL-AO to detect whether the baby wet the bed, through the SY sound monitoring module to detect whether the current baby crying, when the detection of baby crying, sound and light alarm to remind parents. Then, keil5 is used to program, write and debug the main program, data acquisition function subroutine, key subroutine, and so on. Finally, the software and hardware are used to debug the real thing. The debugging results show that the system can realize the accurate detection of the crib, so that the infant environment is greatly improved, and the guardian can also handle the situation of the infant in real time.Based on single-chip microcomputer control technology and sensor detection technology, through the combination of hardware and software, design of an intelligent baby monitor device, through the physical test, the device can automatically complete the baby monitoring operation under the condition of no one, solve the problem of baby monitoring difficulties, the baby monitor after improvement, perfection, has a certain practical value and promotion prospects.
