【摘要】 安防系统是一项被人们日益重视的新兴产业,就目前发展看,应用普及越来越广,科技含量越来越高。几乎所有高新科技都可促进其发展,尤其是信息时代的来临,更为该专业的发展提供了良好的契机。但我国的安防产业发展起步晚、市场环境发育尚未成熟,无论是在技术上和生产规模上,我国安防产业都还处在发展的初级阶段,与国外发达国家相比,我国安防产业目前的差距主要是安防产品科技含量不高,缺乏创新人才,引进国外技术消化应用时间较长。现在最关键的问题还是技术壁垒。目前,安防产业朝着信息化、网络化、数字化发展已是大势所趋,作为信息技术、信息产业相对落后的发展中国家,我国安防行业面临严峻的技术考验。本文介绍了一种利用嵌入式系统体积小,功耗低,便于移动等特点设计出的具有无线安防报警、远程监控、娱乐等功能的可移动式监控手持设备。报警时采用响铃并向默认手机发送短信进行报警。远程监控采用无线网络来传输视频流,可同时对多个地点实时监视,设备上的全球通信移动系统提供基本的通话和短信功能。另外,本系统还具有个人数字助理功能。该设备所完成的功能在各种监控环境中应用极其广泛,本系统经过反复测试,可完成预期的所有功能。工作人员可随身携带该设备在整个工作范围内进行工作。实验结果表明,所设计的系统功能上完全达到设计的预期目标,并具有高可靠、实时性和人性化的特点,达到了实时监控、便于携带、移动方便的目的。更多还原

【Abstract】 Security system is a growing emphasis by the emerging industries, on the current development, the universal application of an ever-increasing technological content getting higher and higher. Almost all high-tech can promote their development, particularly the advent of the information age, the more professional development opportunities. But the Security Industry Development in China started late, the market has yet to mature development environment. Both in the technical and production scale, the Security Industry in China is still in an early stage of development, compared with developed countries, China’s current gap between the Security Industry Security is not high scientific and technological content of products, lack of creative talents , the introduction of foreign technology application takes longer to digest. Now the crux of the matter is technical barriers. At present, security in the information industry, network-based, digital development is the trend of the times, as information technology, the information industry is relatively backward developing country, China Security Industry facing serious technical challenge.This paper mainly discussed a kind of portable device which is functioned with wireless alarm , remote supervise and entertainment and made use of the characteristics of small volume and low electric consumption. It both ring alarms and send message to the owner’s cellar phone number when alarming. It uses wireless network to transfer streaming video and can simultaneously watch many points. The GSM modem applies the basic voice phone and SMS functions. Meanwhile, this system is also capable for digit assistant. The experiment tells that it has fully achieve the goal and highly reliable, real-time usable and friendly.The device functions by monitoring the environment in a variety of applications in an extremely wide range of the system after repeated testing, expected to be completed all the features. Staff can carry the equipment in the whole work and the work carried out within the framework. The experimental results show that the system designed to meet the design fully functional targets, and with high reliability, real-time and the characteristics of human nature, to real-time monitoring and portable, mobile convenience purposes.更多还原
