【摘要】 随着超大规模集成电路、通信技术、单片机技术的迅猛发展和人们保安意识的日渐提高，利用单片机及其它外围芯片实现自动报警已成为可能，而且是一种发展趋势。它不仅有体积小、安装方便、功能较齐全等优点，而且有很高的性价比，因此应用前景广泛。但是现有市场上的家用报警器都有一些不足之处，所以在现行产品的基础之上研制一种新型的家用自动报警器，进一步完善报警器的功能，提高它的可靠性，具有实际意义。这对于保障居民的生命财产安全，提高公安、消防、医疗、保安等部门的快速反应能力，有着重要的价值。 本文在现有的家庭报警器基础之上，将无线通信模块引入报警系统，使系统可通过固定电话线和无线通信模块向外界报警，这样就克服了报警器因电话线被恶意剪断而失去报警功能的问题。 采用模块化的设计思想，系统功能划分为五部分：主模块、移动通信模块、警情采集模块、人机接口模块和红外遥控模块。用户可以根据自己的需要和经济承受能力，购买相应的模块组合成满意的家庭报警器。主模块是系统的核心模块，其它部分作为功能模块，它们与主模块连接简单。在主模块中预先留有各个功能模块的接口，并且将它们相应的软件驱动程序存入主模块之中，可以实现即插即用。 本文对以上五个部分的软硬件设计作了详细的阐述，详细介绍了核心芯片的选型，外围电路的连接，芯片与芯片之间的连接电路，程序设计方法和相应的软件，并给出了关键软件的程序源代码。 根据项目的要求研制了一款家庭报警器，满足用户要求。本文在最后指出了家庭报警器的发展方向。更多还原

【Abstract】 With the dramatic development of VLSI (very large-scale integrated circuit), the telecommunication technology and MCU (micro-control unit) and the improvement of people’s awareness of security it is possible to set alarm automatically by micro-controller and other chips, which becomes a kind of trend. Because it is small and convenient to install and the ratio of performance and cost is high, it will have a bright future. But the product of alarm for family has some disadvantages. It is necessary to do some research on a new type of product based on the former product, which is valuable for protecting people’s possession and increasing the reaction of policeman, fireman, doctor and vigilance committee.This dissertation improves the former alarm for family in which the mobile modem module is introduced. So the alarm can be set by telephone and mobile phone, which overcomes the shortcoming that the system will be out of work when the telephone line is cut off deliberately.The alarm is designed by modular method. The alarm is subdivided into five parts that include the main module, mobile module, collecting information on alarm module, interface of human and machine module and remote control module. According to different requirement and expense, the custom can purchase different modules combine the product that is suitable for them. The main module is the key group of the alarm. The others are the function components, which are connected conveniently with the main module. There are interfaces to connect with the function modules and software to drive the function modules in the main module, which enables the function modules to plug and play.This dissertation describes the design of hardware and software of the alarm in detail, in which selecting suitable chips, periphery circuit, chips interface, and the methodology of program are discussed. Moreover, the key program is described.The alarm that is satisfied for the custom is developed in terms of the requirementof project. The development trend of alarm is discussed in the end.更多还原
