摘要:
奶瓶作为每个育儿家庭必备的刚需产品,其安全问题是家长和社会广泛关注的热点话题之一。为满足家长对奶瓶的智能化需求,本文设计一款基于STC89C52单片机智能奶瓶温控系统,保证婴儿在使用过程中的安全。本设计通过防水式DS18B20传感器测量奶瓶中饮品的温度,通过按键可以设置温度上下限值和切换模块,通过显示屏显示饮品的温度值,通过语音播报模块进行语音播报。奶瓶温控系统有两种模式,即恒温模式和加热模式,使奶瓶中的液体随时保持在特定的温度范围内,供婴儿随时饮用。本设计不仅需要符合可持续发展理念,还需要考虑以人为本的思想观念,使产品设计更加人性化和智能化。

Design of milk bottle temperature control system based on single chip microcomputer
Abstract:
As a necessary product for every parenting family, the safety of milk bottle is one of the hot topics concerned by parents and the society. In order to meet the intelligent needs of parents for milk bottles, this paper designs an intelligent temperature control system for milk bottles based on STC89C52 microcontroller to ensure the safety of babies in the process of use. In this design, the waterproof DS18B20 sensor is used to measure the temperature of drinks in the bottle. The upper and lower temperature limits and switching module can be set by pressing the button. The temperature value of drinks can be displayed on the display screen, and the voice broadcasting module can be used for voice broadcasting. The bottle temperature control system has two modes, namely constant temperature mode and heating mode, so that the liquid in the bottle is kept in a specific temperature range at any time for the baby to drink at any time. This design not only needs to conform to the concept of sustainable development, but also needs to consider the concept of people-oriented, so that the product design is more humane and intelligent.
