Description
Technical field
Along with the foundation of China market economic system, the development of science and technology, China's security protection industry is constantly pushed ahead, and oneself becomes the hi tech market that an embodiment public safety emerging, that have a high potential and technical precaution are combined closely security protection market, for the development of security protection enterprise provides rare opportunity.And there is in the world the hugest security product market in the just quick China in line with international standards of domestic security protection industry, and this is the advantage of our maximum.In the develop rapidly on the original basis especially of European and American developed countries' security protection industry, in other developing countries, as Asia, Latin America, Eastern Europe, Africa and the Middle East, also can predict its rapid growth.These areas also have the very large security protection market of not developed, and the feature in these markets is that crime rate just develops rapidly in continuous increase, economy, and therefore, these countries are also increasing gradually to the demand of safety practice and security method.So research warning system has good social value and economic worth.On society, burglary-resisting system is more and more subject to people's attention, and develops rapidly in national economy, and under the promotion that living standards of the people improve day by day, people are growing to the demand of safety, also more and more darker to the understanding of security protection.Particularly, the large project such as " national Emergency System ", " safe city ", " Safe Campus ", " science and technology is alert by force " is in national expansion, and the important International Operations such as " Olympic Games ", " World Expo ", " Asian Games ", " Games for university students " is held in China, promoted security protection industry to develop rapidly, security protection industry has presented a flourish good momentum.Recent years, statistics showed: the security protection industry of China on average shoots up with the annual growth of 15%-30%.
But, although it should be noted that although the development of the security protection industry of China presents actively, lasting, quick, sane good situation, but in the development of China's security protection industry, also there are a lot of problems, seriously restricting the healthy long term growth of China's security protection industry.Mainly appear at China's security protection industry industrial structure extremely unreasonable, mountain vallage phenomenon is prevailing, and product is manufactured in a rough and slipshod way, and lacks technology content, extensive growth ... and so on, make security protection industrial adjustment upgrading cry more and more.Key is that product level is low, and high added value, high-end product are few.
To the general designation for there is the electronic product giving the alarm with forms such as sound, light, electric waves under the situations such as alert, danger, emergency condition.Along with scientific and technological progress, mechanical alarm device is replaced by advanced electronic alarm more and more, is often applied to the fields such as the system failure, safety precaution, communications and transportation, medical aid, emergency disaster relief, with social production, life inseparable.
Guard against theft and alarm system is by physical method or electronic technology, and automatic detection occurs in the intrusion behavior of deploying troops on garrison duty in monitored area, produces alerting signal, and points out operator on duty that the position, region of reporting to the police, the system that demonstration may take some countermeasures occur.Guard against theft and alarm system is the critical facility of the unscheduled events such as pre-rob-proof, theft.Once generation accident, just can accurately show the site of an accident in security control center by sound and light alarm signal, makes in taking emergency measures rapidly.Guard against theft and alarm system has formed security system together with gateway control system, closed-circuit TV monitoring system, caller interphone system and electronic patrol system etc. and guard against theft and alarm system is made up of detector (claiming again burglar alarm), transmission channel and alarm controller three parts conventionally.Alarm detector processed and formed by sensor and signal, is used for detecting intrusion person intrusion behavior, and the device being made up of electronics and mechanical part, be the key of guard against theft and alarm system, and sensor is the core parts of alarm detector.Adopt the senser element of different principle, can form variety classes, different purposes, reach the different warning sniffers of surveying object.Or household alarm mainly utilizes existing telephone network wireless phone GSM network, or by wireless wired mode, be communicated with owner phone, or mobile phone, realize the electronic product of remote anti-theft function.At present popular product mainly contains anti theft host and a series of alert detector composition of an acknowledge(ment) signal on the market, as infrared eye.Door magnetic, smoke detector, infrared palisade etc.
Domestic have a lot of manufacturer production burglar alarms, and part alarm adopts the former cartridge chip of imported from America, and microcomputerized control technology, is intellectuality, full digital code, the multi-functional technical precaution fine work of new generation that integrates sensor measuring, communication, computing machine.Some burglar alarm also can, by specific communication format and public security 110 alarming and managing center calculation interconnect planes, form a set of advanced person's comprehensive scientific and technical safety precaution network.Once generation alert, phone, mobile phone, the beeper that warning message can be set to user by post and telecommunications network moment remote transmission.At present, the classification of burglar alarm has:
One, dialing burglar alarm, utilizes main frame, or by all kinds of detectors of wireless wired connection, realizes antitheft
Warning function.Main frame is connected and fixed telephone wire, and if any alert, or the mobile phone phone number dial of setting according to client is reported to the police;
Two, GSM burglar alarm, utilizes main frame, or by all kinds of detectors of wireless wired connection, realizes anti-theft alarm function.The built-in GSM mobile handset card of main frame, if any alert, or the mobile phone phone number dial of setting according to client is reported to the police;
Three, local burglar alarm, utilizes main frame, or by all kinds of detectors of wireless wired connection, warning signal is reported to the police and realized warning function.
Four, multimedia-message-alarming device, main frame is transferred to alarm picture on alarm center or related personnel's mobile phone or in mailbox by GPRS.
Background technology
The present invention relates to technical field of security and protection, a kind of induction type anti-theft alarm device is provided.
Summary of the invention
The object of the present invention is to provide a kind of a kind of induction type anti-theft alarm device based on Doppler effect.
The present invention is to achieve these goals by the following technical solutions:
