Description

A kind of radiating circuit of infrared safety device

Technical field

The present invention relates to technical field of security and protection, a kind of radiating circuit of infrared safety device is provided.

Background technology

Foundation along with 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 in national economy, develops rapidly, 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%.

Yet, although it should be noted that although the development of the security protection industry of China presents actively, lasting, quick, sane good situation, in the development of Dan China 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.

General designation to the electronic product for occurring to give 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 in the monitored area of deploying troops on garrison duty, and 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 consists 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 comprised 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's phone, or mobile phone, realize the electronic product of remote anti-theft function.Anti theft host and a series of alert detector that at present popular product mainly contains an acknowledge(ment) signal on the market form, as infrared eye.Door magnetic, smoke detector, infrared palisade etc.

In departments such as industrial or agricultural, fire-fighting, bank, hotel, market, space flight, often need to environment be monitored and be reported to the police, to prevent that stolen behavior from occurring, and bank, hotel etc., burglar alarm is vital especially.In burglary-resisting system in the past, generally adopt the technical measures such as pyroelectricity, microwave to gather human body invasion signal, these are when indoor application, there is good effect, yet in many occasions as places such as enclosure wall and courtyards, deploy troops on garrison duty, above carried measure rate of false alarm in practice is high, sometimes even cannot normally work.

We know, in conventional environmental parameter, human body intrusion detector is very easy to be subject to the impact of environment and makes parameter change, maturation along with infrared ray and laser technology, many infrared theftproof and laser anti-thefts that apply to outdoor occasion start to be born, because light is linear transmission, at transmitting terminal transmitting light beam, middle as unobstructed, receiving end just can be received normal light beam; When having people's process to deploy troops on garrison duty region, light beam is blocked, and now receiving end just cannot receive light beam, thereby starts warning circuit work, reaches the object of warning.
