基于自动拍照传输图片的手机嵌入式报警器架构及关键技术研究

The framework and the key technology of the alarm embedded in a mobile phonebased on automatic photographing and transmitting the photos

利用手机设计一种个人随身报警器。基于ARM11手机,以手机照相模块和彩信模块做为主要部件,首先把手机拍照模块和闪光灯电路模块与手机照相机快捷键相串接,然后在Symbian智能手机系统的S60平台上采用carbide.c++语言实现在硬件底层的手机照相机快捷键被触发后MCU进行快速中断启动键盘解锁并调用JAVA程序,最后在WTK平台上采用J2me语言实现手机自动拍照通过彩信传送图片给指定手机。在紧急情况下一旦用户触发手机照相快捷键,手机立刻解开键盘锁,闪光灯亮,并自动对现场情景照相后把图片通过彩信发送给亲友,以便亲友能及时采取措施对用户提供帮助,同时也为事件取证做好信息保存。手机嵌入式报警器可有效保障个人人身和财物安全。

Abstract：To design a perrsonal alarm with one by a mobile phone. Based on the ARMll mobile phone, the mobile phone camera module and MMS module were the main components, at first connected the mobile phone＇s camera module and the flash circuit module were connected with the mobile phone＇s camera shortcut key in series, then used the carbide, c~ ＋ language on $60 platform of the Symbian smartphone OS to realize that the MCU interrupted by FIQ, unlocked the keyboard and invoked the JAVA program after that the mobile phone＇s camera shortcut key of the hardware bottom was touched , at last use d J2me language on the WTK platform to realize the mobile phone ＇ s automatic taking pictures and sending pictures by MMS to the designated mobile phone. In case of emergency once the user triggered the mobile phones＇s camera shortcut key, the mobile phone immediately unlocked the keypad, the light flashed ,automatically raked a picture for the scene and sended the picture through mms to the relatives and friends, so that they could take timely measures and provide help to the user, also preserve the information in order to take the evidence. The alarm embedded in the Mobile phone can effectively protect personal safety on body and property.
