随着科学技术的进步，监控系统的设计越来越人性化、智能化，这已成为现代监控系统的一个新的发展方向。作为监控系统的终端，语音提示报警部分扮演了重要的角色。该课题正是针对如何实现语音提示报警进行了研究。
该课题分析了语音提示报警方式的优越性，并提出了一种基于单片机AT89S51、GSM模块TC35i以及语音芯片ISD2560实现远程监控语音提示报警部分的设计方案。具有成本低、数据传送速率快等优势。该课题通过对AT89S51、TC35i以及ISD2560数据手册的研究，对GSM网络通信的分析，设计了相应的电路图，编写了相关程序，实现了语音提示报警功能。即使在远离监控现场的任何一个终端，只需要通过语音提示报警终端发出的警报，给值守人员进行预警，就能让值守人员及时解决险情。该方案为语音提示报警部分的设计提出了一个合理的解决方案。

ABSTRACT
                                  
Along with the progress in science and technology, control system designing becoming more and more humanization and intelligent, it has become a modern monitoring system to a new development direction. As the terminal control system, voice alarm part has played an important role. The subject will have a study for how to achieve voice alarm.
   The subject has analysised the superiority of voice alarm, and raises a design program which is based on a micro controllers AT89S51, GSM module TC35i and voice chip ISD2560 achieving remote control voice alarm. It has advantages of low cost; fast data transfer rate and so on. The subject with studying for the manual data of the micro controllers AT89S51, GSM module TC35i and voice chip ISD2560, and by a analysis on the GSM network communication, designs the corresponding circuit, writes the relevant procedures, to achieve voice alarm function. Even at any one terminal, which is far from the control scene, it only through voice alarm alerts issued by the terminal, giving a warning to the officers on duty, who will be able to promptly resolve dangerous situations. The program offers a reasonable solution for the designing of voice alarm part.
