Description

The carry-on alarm anti-theft of burn out check

Technical field

The utility model relates to a kind of electronic installation that is used for the important item burglar alarm; Be mainly used in the antitheft of electric bicycle, also can be used for pigsty (cattle and sheep circle, chicken and duck circle) antitheft, bicycle theft-prevention, motorcycle anti-theft, automobile burglar, notebook computer antitheft or the like.

Background technology

Electric vehicle anti-theft alarm device in the market, major part all are to work in the vibrations detection mode, are running into situation such as thunder, set off firecrackers; Be prone to false alarm; Often disturb residents, in addition, when people park or take out oneself vehicle a crowded parking area before, will move others' vehicle; False alarm also can take place in the vehicle of being moved, and also can disturb residents.Listing four kinds of immediate prior aries below describes:

1. the on-the-spot vibration alarm of electric motor car.Vibration detector and alarm are installed onboard, set up defences and withdraw a garrison with telepilot, and when vehicle body is moved or meets vibrations, the alarm on the car just sends the chimes of doom of shrillness.This alarm is prone to false alarm, often disturbs residents.When car stolen, if the car owner is not at the scene, so no matter how reported to the police at the scene, and the car owner also can't hear, even if heard that also not knowing is the sound that sends on the own car, so that vehicle still is easy to is stolen.

2. a bicycle electronic anti-theft warning horn (the patent CN96207694.5 of cessation of patent right).Transmitter is made the vibration detecting element by the piezoelectricity perceptron, when vehicle body is moved or meets vibrations, does not send alarm sound on the car, and the receiver that the car owner carries can be reported to the police at once.This warning horn is prone to false alarm, though can not disturb residents, the own regular meeting of car owner is disturbed to be much troubled.

3. electric motor car bidirectional alarming alarm.Vibration detector and alarm are installed onboard, set up defences and withdraw a garrison with telepilot, and when vehicle body is moved or meets vibrations, the alarm on the car just sends the chimes of doom of shrillness, the telepilot that the car owner carries also together with the time report to the police.This alarm is prone to false alarm, not only often disturb residents, and car owner oneself also regular meeting disturbed and be much troubled.

4. burn out check dialing guard against theft and alarm system.Extending two leads in the wire breakage detector fastens on the article that need antitheft; The closed loop that forms, when the burglar broke lead, alarm sound was not sent at the scene; Wire breakage detector sends wireless signal and gives near main frame, and the main frame onsite alarming is also called to owner.The host power consumption of this burglary-resisting system is bigger, and built-in rechargeable battery stand-by time is short, need remain attached to power taking on the commercial power socket; So main frame can only fixed placement in doors, and its host function is complicated, volume is too big; So can not carry, still, when electric motor car is far away apart from main frame (for example owner leaves home to go out to handle affairs by bike); Main frame does not just receive the wireless signal that detector sends, and system just can not play the effect of electric motor car antitheft.

Summary of the invention

Technical matters to be solved: in order to overcome prior electric car burglar alarm or easy false alarm, often to disturb residents; Perhaps can not notify the car owner; The deficiency that perhaps can not carry; And only limit the use of in the deficiency of electric motor car antitheft, the utility model creatively wire breakage detector and the combination of portable warning machine, provides a kind of new-type electronic anti-theft warning horn; The needs that can adapt to no false alarm, not disturb residents, when car stolen, can notify the car owner, can carry, and the antitheft occasion that also can be used for some other article except that electric motor car.

The technical scheme that is adopted: the utility model is made up of two parts of wire breakage detector and carry-on alarm.Wire breakage detector all is incorporated with powered battery with carry-on alarm the inside, and wire breakage detector is fixed on the vehicle body and (can places in the car seat support), and alarm is for carrying with oneself.Pass through the transmission that electromagnetic wave is realized wireless signal between wire breakage detector and the carry-on alarm.

Wire breakage detector is made up of lead, broken string trigger circuit, wireless transmitter module (comprising emitting antenna).The two ends of lead are connected J1, J2 two places of broken string trigger circuit through connector, and the output terminal of broken string trigger circuit is connected on the power supply input end of wireless transmitter module.

Alarm is made up of wireless receiving module (comprising receiving antenna), driving circuit, warning circuit with oneself.The data output end pin of wireless receiving module is connected on the input end of driving circuit, and the output terminal of driving circuit is connected on the power supply input end of warning circuit.

Any difference among electronic vehicle body, electric wheel, battery of electric vehicle, these four kinds of things of ground fixture body (the for example railing in roadside) or any three kinds or whole four kinds of things; Be buckled together with lead; The two ends of lead are connected with J1, J2 two places of wire breakage detector through a public female connector; Force the burglar to have to before break lead earlier that (pulling out lead is connected with the connector that breaks between the trigger circuit stealing car (or battery of power stealing motor-car); Perhaps directly cut off lead), do not break lead and just can not steal vehicle or battery.Lead is in case broken; Off-state is just changed into by conducting state in J1, J2 two places, and the broken string trigger circuit are with regard to triggering and conducting electronic switch Q1, and wireless transmitter module gets the electrician and does; There is modulation the electromagnetic wave of address code and numeric data code to launch through antenna; After several seconds, the electronic switch Q1 of broken string trigger circuit recovers off-state automatically, and wireless transmitter module stops emission.

When the antenna of carry-on alarm receives the electromagnetic wave that wire breakage detector sends; After wireless receiving module decoding identification, in the respective pins output high level of data output end, the electronic switch Q3 so the conducting of driving circuit; Warning circuit must the electrician be done, and begins to report to the police.Type of alarm can be the combination of any one or any two kinds or whole three kinds of modes in the middle of vibration, luminous, three kinds of modes of sounding.The wireless receiving module of alarm works in the self-locking pattern with oneself; So when wire breakage detector stopped launching electromagnetic wave, the data output end of wireless receiving module continued output high level, warning circuit continuous firing; Up to user's power cutoff switch SW, alarm just can stop to report to the police with oneself.

Wireless transmitter module and wireless receiving module can arbitrarily have been bought in each electronic market, are a kind of universal electric parts, and its principle of work and method of application are well-known, repeat no more here.

The beneficial effect of the utility model is: thunder running into; Situation such as set off firecrackers; And people park or take out the vehicle of moving others before oneself the vehicle mutually a crowded parking area, are can not break lead, and wire breakage detector is launching electromagnetic wave not just; Just false alarm can not take place, can not disturb residents yet.Only under the situation that the burglar will steal, just can break lead to electric motor car (or battery of car), at this moment the timely alert notice car owner of alarm meeting with oneself arrives in parking site as early as possible after the car owner receives a crime report, and is caught on the spot the burglar probably!

Warning machine structure has been given up secondary function through simplifying, and makes its power consumption still less, can use battery independently-powered; Make its weight lighter, volume is littler, can carry.

Wire breakage detector is independently-powered by internal battery, so can arbitrarily be installed on the various places and article that need to guard against theft.Again with lead buckle jail after for example closing well to the door of pigsty (cattle and sheep circle, chicken and duck circle); Patch lead on wire breakage detector at last; The time break lead in the theft of opening the door as the burglar so, the timely alert notice owner of alarm with oneself, adaptation is to the antitheft needs of domestic animals and fowls; Fruit patches on wire breakage detector after fastening bicycle or article such as motorcycle or automobile or notebook computer with lead for another example; Force the burglar at the theft lead of having to break earlier before the respective articles; If not breaking lead just can not steal respective articles, so just can adapt to antitheft needs to these article that fastened.
