【摘要】 在21世纪,随着中国经济的快速平稳健康可持续发展以及城镇居民生活水平的快速提高,很多小区都安装了智能报警系统,从而大大提高了小区的安全程度,有效保证了居民的人身与财产安全,并为安防产品市场提供了广阔的发展前景。在第一章中,作者对本课题研究的背景以及国内安防产业发展概况进行了介绍,并分析了国内安防产品存在的部分问题,并提出了本课题的三个研究方向:1、研究室内安防系统,实现系统自动布防撤防,解决系统延迟问题;2、避免破坏室内原有布线问题并使系统能正常工作,解决室内布局问题;3、选用性价比合适的语音识别系统,并使用较为合理的识别算法,解决智能识别问题。在第二章中,本文设计了一款改进型室内安防系统,包括输入模块、传输模块、系统模块、输出模块四部分硬件电路及其相关程序模块。其中系统模块由AT89S51单片机系统以及存储模块、按键模块、电源模块组成;输出模块主要包含语音模块以及电话模块组成;传输模块则包含室内380V/220V低压电力线路和系统输入模块、系统模块与电力线的接口电路;输入模块主要包括前端防盗/探测模块以及其抗干扰模块;在第三章中,本文对系统进行硬件电路设计,包括电路使用的芯片介绍、各模块电路及各模块之间的接口电路;在第四章中,本文对系统各个模块的软件设计策略进行了阐述,并通过流程框图的方式表达出来;在第五章中,本文对产品系统的硬软件进行了整合。在第六章中,作者对本文中所做的工作进行了总结,并提出了对于未来该领域工作的展望。本文针对国内一些知名品牌安防产品存在的问题,提出了一款改进型室内安防系统设计方案,为室内安防产品的今后发展提供了理论指导。更多还原

【Abstract】 With the rapid development of social economy and our nation’s living standard,, a number of guard and alarm systems have been set up in our residential quarters, so people will enjoy a better living environment and the properties will be safe, and the alarm systems will meet their bright future.In the first paragraph, we will discuss the background of alarm systems in our country at first. Then, according to their insufficient parts, we will better them in these three directions. Firstly, this equipment can automatically work and quit according to the actual actions of the houses; Secondly, the communicating signals will go through the power transmission lines after being modulated .At last, in order to ensure the safety of the family ,we must use the language-definition system to distinguish the identifications of all the guests.In the second paragraph, we have design a set of improved-interior alarming system, which has been divided into four parts: the input module、the output module、the system module and the transmission module. The input module includes the sensor circuits and noise filters; the transmission module is composed of the power-line and the interface circuits between the input module and the system module; the system part includes the MCU system、its memory part、its keypad part and its power part; the output module consists of the tone part and the telephone part.; In the third paragraph, we will design the hardware of each module, their interface circuit and the relating chips; in the fourth paragraph, we will introduce the program codes; In the paragraph, we will combine all of them together and make a conclusion of the improved functions of the system.In last paragraph, we will make a conclusion of this article.In this article, we have designed a set of improved interior alarming system. So we can provide the theory guides for the predecessors in this science project. And what’s more, we can provide a specific mode for the next generations of this product.更多还原
