基于蓝牙4.0的家庭儿童智能防护系统设计

Design of Child Intelligent Protection System on the Strength of Bluetooth 4. 0

针对当前儿童在家里出现的意外情况,提出了基于蓝牙4.0的家庭儿童智能防护系统,它的应用对象主要是缺乏安全意识的十岁以下儿童。本文主要从系统设计方案、硬件设计及软件设计方面给出了家庭儿童智能防护系统的设计思路,当携带可穿戴设备的儿童进入危险区域(如入户门、窗户等),主控设备和可穿戴设备建立连接,打开超声波传感器,获取儿童离危险区域的距离值,主控设备进行判断,看是否需要关门或关窗,从而达到智能防护的效果。

In view of the unexpected situation of children at home,this paper proposes a family child intelligent protection system on the basis of Bluetooth 4.0,which is mainly applied to children under the age of ten who lack security awareness.It gives a design idea of the family child intelligent protection system in terms of system design,hardware design and software design.When children carrying wearable apparatus enter dangerous areas(such as doors,windows),the main control device will automatically connect the wearable apparatus,turn on the ultrasonic sensor to learn the distance of the child from the dangerous area,and then determine whether to close the doors or windows,so as to achieve the effect of intelligent protection.
