Description

A kind of family expenses vibration alarm for safety guard

Technical field

The utility model design technical field of security and protection provides a kind of family expenses vibration alarm for safety guard.

Background technology

Foundation along with the 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 characteristics in these markets are 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 the research warning system has good social value and economic worth.Burglary-resisting system more and more is subject to people's attention on society, 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, and are 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 the expansion in the whole nation, and the important International Operations such as " Olympic Games ", " World Expo ", " Asian Games ", " Games for university students " is held in China, promoted the security protection industry to develop rapidly, the 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, 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, the mountain vallage phenomenon is prevailing, and product is manufactured in a rough and slipshod way, and lacks technology content, the 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 the electronic product that occurs to give the alarm with forms such as sound, light, electric waves under the situations such as alert, danger, emergency condition.Along with the progress of science and technology, the mechanical alarm device is replaced by advanced person's electronic alarm more and more, often is applied to the fields such as the system failure, safety precaution, communications and transportation, medical aid, emergency disaster relief, and is inseparable with social production, life.

Guard against theft and alarm system is with 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 the regional position of pointing out the operator on duty to report to the police, the system that demonstration may take some countermeasures.Guard against theft and alarm system is the critical facility of the unscheduled events such as pre-rob-proof, theft.In case the generation accident just can accurately show the site of an accident in security control center by the sound and light alarm signal, makes in taking emergency measures rapidly.Guard against theft and alarm system has consisted of 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 of detector (claiming again burglar alarm), transmission channel and alarm controller three parts usually.Alarm detector processed by sensor and signal and forms, and is used for detecting intrusion person intrusion behavior, by the device that electronics and mechanical part form, 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 consist of variety classes, different purposes, reach the different warning sniffers of surveying purpose.Or household alarm mainly utilizes existing telephone network wireless phone GSM network, or by wireless wired mode, is communicated with owner's phone, or mobile phone, realizes the electronic product of remote anti-theft function.At present the popular product anti theft host and a series of alert detector that mainly contain an acknowledge(ment) signal forms on the market, as infrared eye.Door magnetic, smoke detector, infrared palisade etc.

Summary of the invention

The object of the present invention is to provide this circuit design to get simple and clear, use components and parts few, its function is obvious, and stability is high, is difficult for producing false alarm.Highly sensitive, with low cost a kind of family expenses vibration alarm for safety guard.

The utility model is by the following technical solutions to achieve these goals:

a kind of family expenses vibration alarm for safety guard, it is characterized in that: the involving vibrations sensor, resistance R 1-R7, capacitor C 1-C2, triode Q1-Q2, chip NE555, Music Clip KD-9561, the LED light emitting diode, loudspeaker, the base stage of described resistance R 1 connecting triode Q1 and power supply VCC, Q1 provides base voltage for triode, described vibration transducer, in parallel with R1, the collector of described resistance R 2 connecting triode Q1 and power supply VCC, Q1 provides collector voltage for triode, the collector of described triode Q1 connects the TRIG pin of chip NE555, the CVOLT pin of described chip NE555 is by capacitor C 2 ground connection, described resistance R 7 meets series capacitance C1 after power supply VCC, resistance R 7 is held with the THR end and the DISC that are connected chip termination NE555 of capacitor C 1, the OUT port of NE555 connects 5 pins of Music Clip KD-9561, 6 pins of Music Clip KD-9561 also 7 pins connect by resistance R 4, the 2 pin ground connection of Music Clip KD-9561, 3 pins of Music Clip KD-9561 connect the base stage of triode Q2, the collector of described triode Q2 connects loudspeaker, the on/off of control loudspeaker, the OUT end of described light emitting diode one chip termination NE555, the other end is by resistance R 5 ground connection, described vibration transducer comprises link, magnetite, spring, telefault skeleton and around the intraskeletal telefault of telefault, described magnetite is contained in spring fixing, the described spring that magnetite is housed is packed into fixing in the endoporus of telefault skeleton, described magnetite moves in the telefault skeleton when the spring springing, and described link is drawn telefault.
