Embodiment
With reference to Fig. 1
Described case and bag anti-theft alarm device, wherein the alarm transmission device is provided with battery 1, teleswitch 2, warning circuit (3) master switch (4), alarm switch (5), wireless launcher (UI), loudspeaker Y1.Wherein, battery 1 is with master switch 4, link to each other respectively with teleswitch 2, and teleswitch 2 and warning are opened 5 and linked to each other respectively with warning circuit 3.Warning circuit 3 links to each other with loudspeaker Y1.Alarm switch 5 be arranged on the antitheft object and with the chain installation of its buckle closure.The control signal input warning circuit 3 of the alerting signal of alarm switch 5 and teleswitch 2.
With reference to Fig. 2
Wherein receive warning device and be provided with battery 6 telechiric devices 7, master switch 8, warning circuit 9, wireless receiver U2, loudspeaker Y2.Wherein battery 6 links to each other respectively with warning circuit 9 with master switch 8, battery 6 links to each other with telechiric device 7, wireless receiver U2 links to each other with warning circuit 9, warning circuit 9 links to each other with loudspeaker, the alerting signal input loudspeaker Y2 of warning circuit 9, the control signal of wireless receiver U2 is connected to warning circuit 9.
With reference to Fig. 3
When closed master switch 4 and teleswitch 2, warning circuit 3 is started working.Warning circuit is made of thyristor switch circuit and composite audio amplifying circuit.Wherein the thyristor switch circuit is formed electronic switch by thyristor SCR1 and thyristor SCR2, and alarm switch 5 is closed at ordinary times, not conducting of electronic switch.If this moment, alarm switch 5 was opened, then the electronic switch of warning circuit 3 will obtain trigger current and conducting, and the composite audio amplifying circuit of being made up of triode V1 and triode V2 gets electric, starts working, and makes loudspeaker Y1 sounding, provides warning.When alarm switch 5 by from new when closed.Because thyristor SCR2 is connected to delay capacitor C, warning can continue a period of time.
With reference to Fig. 4
When master switch 8 closures, warning circuit 9 is started working.Telechiric device 7 just can be controlled the conducting of teleswitch 2 or end.Warning circuit is made of thyristor switch circuit and compound frequency amplifying circuit.When receiver when launching within the specific limits, the receiving chip U2 that is integrated in Fig. 4 will receive the signal of transmitting chip U1, this moment is from its 2 pin output high level, 3 pin output low levels, wireless receiving chip U2 does not have high trigger signal and does not work, transistor ends, receiver will can not receive the signal that transmitter sends when object long distance owner certain distance, the 2 pin output of receiving chip U2 becomes low level, 3 pin output high level, the speech chip work that is triggered this moment, after triode amplified, loudspeaker sent chimes of doom from its 4 pin output voice signal.
