The sound equipment difference that common two sound generators can send.

The wireless remote control multiple spot monitoring type infrared anti-theft alarm device that the utility model provides, because design has delay circuit on alarm host machine, when arbitrary group of probe monitored out " people is arranged " signal, and through signal of remote control wireless transmission to alarm host machine, alarm host machine starts delay circuit earlier and produces a time-delay voice prompt signal, when being owner oneself when entering, promptly point out owner to start Digiplex and close " people is arranged " signal, in order to avoid false triggering.In addition, this alarm also divides into groups a plurality of probes, thereby can be when owner or legal identity person enter monitoring range, the probe of closing its region selectively, the probe of not closing in other zone works on, and does not influence whole warning system operate as normal.And existing alarm can only cut out whole warning system usually, thereby the utlity model has applicability and security better.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is the structural representation of a kind of embodiment of the utility model alarm;

Fig. 2 is the circuit diagram of alarm host machine among Fig. 1.

Shown in Figure 1 is the utility model alarm that comprises two groups of probes, every group comprises a plurality of probes, be designated as probe 1 and probe 2 respectively, each probe includes infrared eye and wireless launcher, the principle of work of probe 1,2 is identical, just with the code Design difference that transmits, to reach the functional purpose of grouping.Digiplex 3 is provided with the button of each group probe of control.The configurable number of probe 1, probe 2 and Digiplex 3 can be determined as required.Alarm host machine 4 comprises wireless receiver 5, wireless receiver 6, logic control and delay circuit 7, warning driving circuit 8, alarming horn 9, sound generator 10 and sound generator 11, and its circuit diagram as shown in Figure 2.Wireless receiver 5 is used for " people is arranged " signal that receiving transducer 1,2 sends, and wireless receiver 6 is used to receive " locking " signal that Digiplex 3 sends.Wireless receiver 5 receive the probe 1 or pop one's head in 2 send " people is arranged " signal the time, produce a signal A1 or signal A2 respectively.When Digiplex 3 sent " locking " probe 1 or pops one's head in 2 control signal, wireless receiver 6 produced signal B1 or signal B2 respectively.Signal B1 and signal B2 are that high level is effective, so signal B1, B2 need to be input to logical circuit IC01 together with signal A1, A2 again after integrated circuit (IC) 02 is anti-phase, reach the purpose of signal A1, A2 being carried out logic gate control by signal B1, B2.The function of logical circuit IC03 is as long as there is arbitrary signal effective in signal A1, A2, and again under the condition of latch-up-free signal B1, B2, alerting signal is transferred to subsequent conditioning circuit.Delay circuit is main formation with IC04, and when IC03 had output signal, this signal also triggered delay circuit IC04 simultaneously except that level transmits backward, and the time-delay size is determined by electronic component R1 and C1, generally is approximately 8-10 second.The signal of delay circuit output becomes signal C1 after anti-phase and sends into logical circuit IC05, and alerting signal is carried out from locking.Simultaneously, time delayed signal and A1 or A2 phase logic with after start sound generator 10 respectively or sound generator 11 sends voice prompt.Sound generator 10 can be designed to musical sound etc. with sound equipment corresponding to " people is arranged " signal of first group of probe; Sound generator 11 is corresponding to " people is arranged " signal of second group of probe, and its sound can be designed to the very brief sound of " tick, tick " etc.If in time delay, owner or legal identity person start Digiplex 3 and produce control " locking " signal B1 or B2, then through after logical circuit IC01, the IC03 effect, alerting signal C1 are disappeared, thereby avoid triggering to start alarming horn 9.If after the time delay, still there are not " locking " signal B1 or B2 or B1 and B2, then behind the C2 blackout, the C1 signal just can drive triode D1 and make the relay J action, starts alarming horn 9 work, sends ear-piercing chimes of doom, finishes warning function of the present utility model.
