基于51单片机与GSM的防盗报警器系统设计

防盗报警器系统的核心器件是89C51单片机。把红外探头设置在监测点上,这时的传感器就会感应到能量的变化,然后红外探头就会把人身上的的辐射能量转换成电信号,然后经过放大器、比较器


摘 要:现在的社会,越来越多的人对私有物具有高度重视,他们认为安防市场需要注入新鲜的血液了,来替换旧的“血液”。随着我国新时代的到来,国家越来越重视安防产业,因此安全防护已成为一个新颖的市场。在此时,国家加快公共安全与智能化相结合的技术,安防市场的未来就可以看到“曙光”了。而且我国的安防产业正在快速的与国际安防产业接轨,能够预见未来的安防产业发展蒸蒸日上。现在,我们国家在许多市场上都有了不同程度的发展,尤其在安防市场,国家投入了大量的人力、财力、物力,再加上出台的政策,因此,新型的智能安全防盗报警器系统问世了。在本就激烈的安防市场上又激起了水花,各大企业公司纷纷迅速出击抢占市场。

本次系统的工作原理是通过热释电红外传感器,把电压信号送到89C51单片机上,在信号处理后,微控制器向GSM模块发送命令,模块向用户发送短消息,从而实现远程防盗报警。

Anti-theft alarm system based on 51 single chip microcomputer and GSM

Abstract:  In the nowadays, more and more people private property has been highly valued. They believe that the security market needs fresh blood to replace the old "blood".With the arrival of the new era in China, the state has paid more and more attention to the security industry. Therefore, safety protection has become a new market. At this time, the state has accelerated the technology of combining public safety with technology and defense, In this way, we can see the dawn of the future of the security market, though we hope that opportunities and risks will fail.Moreover, China's security industry is rapidly integrating with the international security industry, The development of the future security industry can be foreseen.Nowadays, our state has change in all professions and trades, particularly security market. The state has inputted into a large number of the arm of flesh, and so on, and the support of the government. So, the new brain power of guard against theft emerge as the time require.In the intense security market, water spray has been sparked, and every big company has launched a rapid attack to seize the market.

What is the point of flammability of this system? Through the sensor, the voltage signal is sent to the 89C51 single chip microcomputer. After the signal processing, the microcontroller transmission order to the GSM module, and the module sends short messages system to the users, so as to realize long distance take precautions against burglars of reporting to the police.

1.1研究背景与意义

从我们国家现在的发展来看,越来越多的市民对私有物具有高度重视,他们认为安防市场需要注入新鲜的血液了,来替换旧的“血液”。随着我国新时代的到来,国家越来越重视安防产业,因此安全防护已成为一个新颖的市场。在此时,国家加快公共安全与技防相结合的技术,由此可以看到,安防市场的未来就可以看到“曙光”了。而且我国的安防产业正在快速的与国际安防产业接轨,能够预见未来的安防产业发展蒸蒸日上。在发达国家中,安防市场更是有巨大潜力的发展空间,例如美国,英国,德国等。再来看发展中国家,它们的安防产业也在与日俱增。但是,要知道在这些地区还有未曾涉足的安防市场,在一些犯罪率较高的地区,安防产业更是必不可少,甚至是说显得尤为重要。因此,越来越多的国家,不管是发展中国家,还是发达国家,都在对安防设施提出了越来越高的要求。所以研究防盗报警系统具有实用性。
