The specific embodiment

Further specify technical solution of the present utility model below in conjunction with accompanying drawing.

Fig. 1 is a circuit structure block scheme of the present utility model, therefrom signal flow and groundwork as can be seen.

Fig. 2 and Fig. 3 are circuit theory scheme drawing of the present utility model, shown that annunciator is different with the front and back position of charger, also indicated because of the detected object difference and caused difference on the detection means, for the alternating current reaction magnetic ring, for the direct current (DC) electric resistance partial pressure, the dotted line among the figure is represented the conduction flexible cord of fixed length with distance.

For all big loading electro-tricycle of power of motor, storage battery weight and vehicle volume,, should select " AC AC system " for use because of its charger is fixed on the vehicle body, annunciator was reported to the police and is cut off source of AC simultaneously automatically before charger.

For large in number and widely distributed, light and handy relatively common electric bicycle,, should select " DC single flow " for use because of its charger separates with vehicle body, annunciator is after charger.

As shown in Figure 2, this AC formula annunciator comprises sound and light alarm parts 4, power converting circuit 5, state selecting switch 6, tripping operation output circuit 7 and the electromagnetic trip 8 of induction by current magnet ring 1, trigger circuit 2, amplifying circuit 3, charged pool, induction by current magnet ring 1 is enclosed within on the lead of charge circuit, trigger circuit 2 are connected on the line bag two ends of induction by current magnet ring 1, amplifying circuit 3 connects the sound and light alarm parts 4 of electromagnetic trip 8 and charged pool by tripping operation output circuit 7, and state selecting switch 6 connects tripping operation output circuit 7.

As shown in Figure 3, this DC formula annunciator comprises the sound and light alarm parts 4 and the power converting circuit 5 of resitstance voltage divider 9, trigger circuit 2, amplifying circuit 3, charged pool, resitstance voltage divider 9 cross-over connections are on two leads of charger circuit, trigger circuit 2 are connected on the mouth of resitstance voltage divider 9, the sound and light alarm parts 4 of amplifying circuit 3 connecting band batteries.

The AC AC system: on the car fixed installation charger electro-tricycle be parked in outdoor or the garage in charge, burglar alarm is put at home, connect vehicle and room by charging cord, enclosure interior at burglar alarm, induction by current magnet ring 1 is enclosed within charger two wires any one, before the charging beginning, state selecting switch 6 is placed " preparation " side, magnet ring line bag two ends induce voltage signal when charging normal, through trigger circuit 2, amplifying circuit 3 and tripping operation output circuit 7 are failure to actuate electromagnetic trip 8, the sound and light alarm parts 4 of charged pool are not worked yet, and state selecting switch 6 are placed " monitoring " side after ready again; In case the robber disconnects after the charging circuit, charging current in the charger circuit drops to zero rapidly, magnet ring line bag two ends induced voltage signal disappears, make electromagnetic trip 8 actions through trigger circuit 2, amplifying circuit 3 and tripping operation output circuit 7, loud " tripping operation sound " appears, the sound and light alarm parts 4 of charged pool send lasting flash of light and alarm voice simultaneously, and the car owner of notice family takes the necessary measures immediately.

DC single flow: the key distinction is that the enclosure interior of burglar alarm is not induction by current magnet ring 1 but break-make situation between resitstance voltage divider 9 sample detecting Car Burglar Alarms and the storage battery, and remainder is similar with " AC AC system ", repeats no more.

Power supply general introduction: the appropriate voltage power supply after each element circuit in this programme burglar alarm all changes by the alternating current 220V direct supply or through power converting circuit, but sound and light alarm parts 4 must be from the charged pool self-organizing system, say that from structure it also is to be independent of outside the burglar alarm housing, be connected to each other by common double conductor cord or radio receiving transmitting module and burglar alarm main body; Prevent exactly just in case AC network has a power failure that from the purpose of charged pool the car owner not necessarily can in time learn, " power failure space " appears thus utilized lost vehicles by the robber.Even the utility model AC network has a power failure, the sound and light alarm parts 4 of charged pool also can in time rely on self energy content of battery to flash and alarm voice, notify the car owner to take measures.

The AC AC system is used main points: the car owner hears two LED light should inspecting burglar alarm after the alarm voice, and the expression AC network does not have a power failure if " going up lamp " works, and should take the way of artificial patrol to prevent that vehicle is stolen; " following lamp " do not work if " upward lamp " is bright, if not electric wire ordinary wear and tear fracture then is artificial dangerous situation to occur certainly, hastens to take the necessary measures.The car owner hears that at home should observe the LED light analysis after the alarm voice earlier is to have a power failure suddenly or the robber occurs, so that take different counter-measures respectively.

Further the analysis showed that, if only for the protection battery-driven car, then " electromagnetic trip 8 " in " AC AC system " can omit need not, still " safety " should comprise the two-layer meaning: the one, guarantee that battery-driven car is not stolen; The 2nd, thus broken string or idle jack is not charged can guarantee that just the third party can not touch electricity by mistake and cause fatal accident.

DC single flow is used main points: also need not the car owner remove manual patrol even AC network has a power failure, auto alarm when having or not alternating current not influence it to run into dangerous situation.

Special prompting: first thing after the car owner receives a crime report must be ensured public security " shutting the dogs up to beat them " by phone, and blockade outlet earlier reexamines vehicle, guarantor's car catches a thief.Otherwise it is late that car owner (particularly high-rise resident family) arrives at on-the-spot possibility downstairs by the time!
