基于AT89S52的婴幼儿智能助手的设计
【摘要】本设计课题来源于生活,以服务于新生代婴幼儿为中心思想,结合发散设计的设计思路,针对婴幼儿的生活习惯特点而设计的一款电子产品。设计以AT89S52单片机为主控器件,通过MLX90614采集牛奶温度或水温信息,温度达到设定的预警温度时,控制ISD4003语音电路语音提示“适合饮用,请放心”。通过嵌入有尿湿检测传感器的尿布检测小孩尿湿的信号;婴幼儿刚睡醒时,触摸到婴儿床的金属护栏时,通过信号放大电路检测这一触摸信号;尿湿信号和触摸信号通过无线发射电路发送给HS0038红外接收头并送至单片机实现软件解码,实现语音播放提示音“宝宝尿湿,请及时更换尿布”、“宝宝睡醒,需要照顾”。本文自上而下,介绍了婴幼儿保姆智能助手从设计到具体实现的主要过程。这是一款帮助新生儿父母和婴幼儿保姆的小型电子产品。

【Abstract】 This design task derives from life and is designed to be a electronic product , which bined with the design idea of spread and characteristics of infants living habits ,centering on serving the new generation design of this electronic product takes AT89S52 SCM as the controller device, collecting milk temperature or water temperature through the the temperature reaches the set warning temperature, the control of ISD4003 voice circuit will prompt “fit to drink, please rest assured”. This electronic product detects wet signals of children through diapers with detection sensor in the infants wake up ,their touch to metal fence of baby beds will be detected through singal amplifier signals and touch signals will be sent to HS0038 through wireless transmitting circuit and carried to the single chip puter for software decoding to realize voice prompt “baby wet, please change diapers promptly,”“the baby woke up and need to be taken care of”.
From top-down , this paper introduces the main process of the nanny intelligence infant from its design to specific realization . This is a small electronic product to help the parents of newborn infants and nannys of infants.
【Key words】 Single-chip puter; Voice recording; Software decoding
