摘要
本文介绍了基于Android智能手机的新型紧急呼救系统。该系统主要由可穿戴式手环和Android手机报警软件APP构成。当个人遇到突发事件时,只要按下手环上的报警按钮,就可通过低功耗蓝牙4.0通信技术,激活遇险人所携带的智能手机上的APP报警软件,并把GPS位置及现场声音信息迅速发送到预设的电话、邮箱,甚至可以直接拨打110等报警电话,为实现自救争取宝贵时间。实验结果表明,该系统功耗低、性能稳定可靠,具有一定的推广应用价值。
The paper introduces a novel emergency call system based on Android phone.This system consists of two elements,including a bracelet and an application of emergency call in Android phone.When someone faces with an emergency,he/she presses the button on the bracelet,the vital emergency sign can be sent to Android phone by Bluetooth 4.0 connection,then the device activates the distress of peo-ple that installed smartphone APP alarm software,the application of emergency call can get the owner’s location information and record the field voice,and then sends this emergency information to other people quickly via short message or Email,and even directly call 1 10. The experiment indicates that the system has advantages of low power,stable and reliable performance,so it has certain application value.
