【摘要】 随着人们生活水平的提高,以及微电子、自动控制和计算机等技术的飞速发展和广泛应用,智能住宅的安全防范系统研究和应用已经日趋成熟。而高等学校作为国家人才培养的重要场所和机构,随着我国高等教育改革的不断深化,高校的校园面积和招生规模以及功能的变化都对高校校园安全管理提出了新的要求,高校校园安全也越来越受到社会各方面的关注。在科技高速发展的今天,利用科技手段来提高高校校园安全防范能力,实现“人防”到“技防”的转变,是营造安全和谐的校园环境的一个重要途径。本文分析了目前高校的构成特点,以及管理所面临的问题,提出了高校校园安防系统的构建方案。并根据高校的特殊情况,以学生公寓的智能化改造为目标,参考国内外智能住宅安全防范技术的发展概况和趋势对照高校安防环境和要求,研究并设计了一种基于单片机系统的学生公寓智能安全防范报警系统,是智能住宅技术在高校的一个创新应用。本智能化报警系统集防盗、防火、节能以及日常显示于一体,除了提供时间与温度的显示和自动警情的检测与报警之外,提出了寝室节能控制的方法,具有一定的创新意义。由红外探测器作为盗警信号和电源节能控制信号的输入端探测器,通过对传统水表的改造实现节水控制,而由温度探测器、光电感烟探测器构成的复合式火灾探测器实现火警信号的检测。这种多传感器技术的应用降低了系统的漏报、误报率,增强了系统的可靠性。当探测器检测到警情信号或者节能信号的时候,就会向单片机发出电平跳变输入,再由单片机通过中断或者查询程序的判断来执行进行相关的控制。另外,本系统还设置了密码验证,通过键盘可输入密码并可修改密码。本系统还配置了备用电源以及具有断电自诊断功能,增强了系统的安全性和稳定性。本系统除了能可靠的实现安防报警之外,通过软件协调,实现资源的分时共用,大大节省了硬件资源。节能模块的提出,对构建节约型校园,提高节能意识,具有一定的促进作用。系统建立在大量相关实验的基础上,并通过硬件及软件仿真验证,证明系统能够稳定的工作,能够达到设计目标的要求,具备一定的实用性,对后续研究开发有一定的参考意义。更多还原

【Abstract】 With great improvement of people’s living standard, the rapid development and abroad application of microelectronics, automation and computer ability, the research and application of security system of Smarthome are more and more successful. The college is an important institution where the country cultivates talented person. Along with deepening high education’s reform of our country, the change of campus area, number of students and function of the college brings on new demands to security management of campus. The security of campus attracts people’s attention. Nowadays, science and technology develop fastly. Changing the safeguard measurement of campus by technology is an important way to build a safe campus.This text analyzes the structure feature of the present colleges and problems of the management encounting. It also suggests the constructure project of campus security system .According to the special situation of college, we will rebuild smart Student apartments. Basing on the development direction, the survey of security technology of Smarthome overseas, the situations of our countries and the college security environment and demand, we have researched and designed a kind of intelligent alarm system for Student apartments basing on single chip microprocessor system. It is a creation of applying Smarthome techology in Universities. It includes the functions of theftproof, fireproof, energy saving and daily display. Meanwhile, in addition to displaying the time and temperature, performing automatic detection and automatic alarm, it also puts forward the approach of apartment energy-saving control. It has some innovation significance. Pyroelectric infrared is used for detecting theftproof and controlling power. Water saving control is achieved by rebuilding of traditional water meter. Temperature sensor and Phoroelectric smoke sensor are integrated to a compound detector for fireproof. The multi-sensors make the least fail to alarm and false alarm, so that it enhances the reliability of the system. When detectors detect any abnormality signal or energy saving signal,an interrupt request will be sent to the MCU. Then the MCU will control the system depending the judgment and performance of the procedure. In addition,the code validation has been intercalated in the system. Users can input and modify the code by keyboard. In order to build up the systemic security and stability, the system has standby power supply and can inspect whether the wire and the power break or not.This system not only can provide security alarm, but can use the resourse at different time according to the software coordination. It can save much more hardware resourse. The suggestion of energy-saving module has some positive effect on constructing saving type campus and improving the conscious of energy-saving. The system can work stability and achieve the design purpose basing on a great deal of correlative experiments, hardware and software’s emulation. The result also proves that it has some definite practicability. As far as research and exploitation, this has some definite significance of reference.更多还原
