【摘要】 在日新月异的今天,随着科技的进步,人们的生活质量一步步提高,生命和财产的安全问题越来越引人关注。当前中国经济持续的高速增长及城市化进程的日益加快,每年数以万计的城市高楼如雨后春笋般拔地而起,别墅豪宅也越建越多,然而城市高层楼宇遭遇灾害逃生难、救援难,在高层楼宇中生活、办公安全感普遍缺失,别墅豪宅一旦发生火灾等灾害损失巨大。尽管现在在市面上已经存在很多的应急通信系统,但是在出现紧急情况时,这些系统都很难达到准确及时的向相关人员、单位传递信息,很多情况下都是要进行人工信息传递,浪费了时间,增大了损失。而且,一般的应急通信系统都是受到诸多条件限制,特别是有线的限制,很多系统都需要专门拉一条线路来达到信息传递的功能。像这种有线的信息通信系统很容易遭到破坏,很多居民楼和商务中心都是采用集中放置配线箱,如果歹徒先打开配线箱把线缆破坏,系统就不可能起到作用了。本文采用GSM无线网络作为信息通信系统的传输媒介,它与传统的线路比较,更加安全稳定,覆盖面广,并且也省下了组建专门的线路的费用,更没有后期对线路的维护。本系统是利用嵌入式处理器通过AT指令来控制GSM模块,使用GSM网络的语音通话和短消息来实现相应的功能。设计了GSM模块的外围电路以及通过QT设计的具有良好用户体验的运行界面的应用程序。当出现紧急情况时,用户可以通过触摸屏,点击相应的一个图标就可以快速的把信息传递到相应人员手机中或者信息中心,这样就可以及时得到救援,让损失减小到最少。本文完成了系统的总体设计和详细设计,硬件上分电源、开机启动、信号显示和来电提醒、串口通信、SIM卡座模块,软件功能模块包括拨号模块、短消息模块、通讯录模块、通讯记录模块、呼入呼出模块、双音多频模块。硬件方面给出了相应的逻辑电路图,软件上有这些功能模块的流程设计。最后本文对课题的研究进行了总结,提出了课题相关的不足之处,并对未来进行了展望。

【Abstract】 Nowadays, with rapidly changing and technology advances, the quality of life step by step improve the life and property safety of growing concern. Along with the constant rapid growth of Chinese economy and the increasingly acceleration of Chinese urbanization process, thousands of tall buildings are built every year, as well as more villas and luxury houses. However, people living and working in tall buildings begin losing their sense of safety for the fact that it is difficult for them to escape and to be rescued should disaster take place in such environment. And if a disaster like fire arises in a villa or luxury house, it would cause great losses. Although there are many emergency communication system in the market now, these systems are difficult to achieve accurate and timely to the relevant personnel when in the event of an emergency, while in many cases, the information is needed to transmit by manual work, so this situation has led to a waste of time, increases the loss. Moreover, the general emergency communications systems are subject to many conditions, especially the cable restrictions, and many systems require specialized to pull a line to achieve the function of the transmission of information. The wired communications systems are vulnerable to damage, and a lot of residential buildings and business centers are centrally located wiring box, if the criminals first to open the wiring box to the cable destruction, the system can not work.The thesis uses the GSM wireless network transmission medium as an information communication system. Comparing with the traditional transmission medium, this medium is more secure and stable, wide coverage, and also save the costs of set up a dedicated line, but not the maintenance of the latter line. This system is in the use of embedded processors through AT commands to control a GSM module, and take the GSM network for voice calls and short message to the corresponding function. The peripheral circuit of the GSM module is designed and a run with a good user experience is designed by QT interface application. When an emergency occurs, the user via the touch screen to click an icon that you can quickly pass information to the appropriate personnel phone or information center and get relief in a timely manner, to reduce the losses to a minimum. The overall system design and detailed design is completed. The entire system includes hardware included power, boot signals and phone calls to remind, serial communication, SIM card module, and software modules, including dial-up module, short message module, contacts module, the log module, inbound and outbound modules, dual-tone multi-frequency module. Hardware gives the corresponding logic circuit diagrams, and software process design of these functional modules.Finally, this thesis has summarized the topic research, proposed the topic related deficiency, and has carried on the forecast to the future.
