核准通过，归档资料。 未经允许，请勿外传！ 摘 要 使用传统婴儿摇篮，需要看护者一直陪伴在婴儿旁边，不仅耗时而且往往使看护者很疲惫。多功能婴儿摇篮控制模块通过单片机的控制，实现了自动控制，减轻了婴儿看护者的劳动负担，促进了婴儿的健康睡眠，提高了大人和小孩的生活质量。目前市场上的智能摇篮，大多数功能都不够齐全，智能化程度不高，本次设计在现有的基础上丰富了摇篮的功能，提高了智能摇篮的实用性。 本文介绍了由单片机控制的新型多功能婴儿摇篮。控制模块由AT89S52单片机作为控制核心，硬件电路分为声音检测、温度检测、湿度检测、电机驱动、人机交互和报警等模块。该系统的功能是：输入的哭声信号控制摇篮的启动，当有温湿度报警信号输入时，启动报警系统。人机交互是由定时按键和LCD组成，摇篮晃动的时间是由按键预置的；LCD可以显示定时时间和婴儿体温、尿床状态。软件部分应用单片机C语言实现了本设计的全部控制功能，包括定时设置、电机驱动、状态显示、报警和音乐播放等。 关键字：单片机；声控；湿度检测；体温检测 Abstract Useing traditional baby cradle, needs nurse to accompany nearby the baby, not only time-consuming moreover often makes nurse to be very exhausted. The multi-purpose baby cradle control module controlled by the microprocessor, has realized the automatic control, lightened the working burden of baby nurse, promoted the babies healthy sleep, enhanced adult and babys quality of life. At present, the functions of the majority intelligent cradle in the market are not very complete, and the intellectualized degree is not high, this design has enriched cradles function in the existing foundation, enhanced the intelligent cradles usability. The microprocessor of AT89S52 takes the master control chip of this design, the function which the cradle realizes includes: 1. when the baby cries calls through the voice control electric circuit control electrical machinery to shake automatically, carries on the hypnosis; 2. the cradle has fixed time function: nurses may establish the time which the cradle shakes according to their need ; 3. when the baby wets the bed starts the auto-alarm through the humidity sensors signal; 4. baby body temperature automatic guardianship function: The body temperature detector carries on the automatic temperature measurement on the babys body, when the babys body temperature surpasses the normal value,it will send out the alarm automatically noticing the nurse pay attention to babys condition.
