单片机家用安全报警系统设计

单片机家用安全报警系统设计(任务书,开题报告,外文翻译,论文12000字)
摘  要
随着科技的不断发展，同时也伴随人们安全意识的不断提高，家用安全报警系统将会有可观的发展前景。本文设计的家用安全报警系统将是一个独具特色的新型电子报警系统。它包含电子探测、智能控制和电话通讯技术等，它具有防火、防盗、防煤气泄漏三大功能。该系统硬件部分主要由主控单元电路、传感器检测电路、键盘接口电路、DTMF拨号电路、显示电路、忙音和回铃音检测电路7大部分组成。
该系统采用了多传感器共同监控的思想，对住宅进行全方位的监控。不管遭遇的险情是火灾、盗窃或煤气泄露，系统都会立刻做出反应，报告出第一现场，并做出相应的现场报警。其中防火模块综合应用了温度探测器、光电感烟探测器进行防火探测，使结果更加准确、可靠，减少因误报或者漏报带来的麻烦与损失；防盗模块应用微波探测器和红外探测器组成的双鉴探测器进行防盗探测，成功的解决了以往由单一传感器漏报和误报率高的问题，增强了系统的抗干扰能力和准确性；煤气泄漏检测模块对CO的含量进行实时监控，一旦超标会立刻发出报警并打开排风扇和关上阀门，可以有效的预防火灾出现和人煤气中毒。本系统还有一大优点，就是能第一时间进行自动拨号报警，即使户主当时不在，也能得到快速的救援。

Abstract
With the continuous development of science and technology, but also with the continuous improvement of people's awareness of security, home security alarm system will have a good development prospects. The home security alarm system designed in this paper will be a new type of electronic alarm system. It contains electronic detection, intelligent control and telephone communication technology and combination, it will have fire, theft, anti gas leak three functions. The system hardware is mainly composed of a main control circuit unit, sensor detection circuit, keyboard interface circuit, DTMF circuit, display circuit, a voice and ring detection circuit is composed of seven parts.
      The system adopts the idea of multi sensors to monitor the whole direction of the house. Regardless of the danger is fire, theft or gas leak, the system will immediately respond to the report of the first scene, and make the appropriate scene alarm. Which fire module of comprehensive application of the temperature detector, photoelectric smoke detectors for fire detection, so as to make the result more accurate and reliable, reduce trouble and losses caused by false positives or negatives.; anti-theft detection of anti-theft module using a microwave detector and infrared detector is composed of detector, the success of solve the past by single sensor false positive and false negative rate high, anti-interference ability and accuracy of the system is enhanced; gas leak detection module of CO content in real time monitoring, once exceeded will immediately send out alarm and open the exhaust fan and close the valve, can effectively prevent fire and gas poisoning. The system also has a big advantage, is the first time to automatically dial the alarm, even if the head of the household is not in, but also the house can get fast resave.
Key Words: singlechip   Fire protection against theft and leakage prevention
