The transmitting set principle of work of this alarm:
By shown in Figure 2, civil power behind transformer T1, D1-D4 step-down rectifier one the tunnel through R1, GR1, give storage battery DP charging, cryptochannel and IC4 input end are sent in another road after filter capacitor C1, C2 filtering.When mains failure, storage battery DP gives each circuit supply of alarm through D5, and R1, GR1 show for charging.
By shown in Figure 2, when pressing reset key AN1, G1 ends, and IC4 control end 5 pin are high level, 2,3 pin output high level, and GR2 is luminous, and alarm is started working.The start delay circuit that G2 among Fig. 3, R29, C11, D10 form is worked simultaneously.Power supply through the eb of G2 knot, R29 to the C11 reverse charging, the G2 conducting, making SCR control end voltage is zero, SCR can not trigger, at this moment F1, F2, F3 detect signal, alarm can not reported to the police yet, indoor occupant can be left away calmly.Clock time C11 charging in about one minute finishes, and G2 is transferred to by 1 conducting and ending, and circuit returns to the normal armed state.
AN2 aims at emergency alarm setting.When owner is in, alarm is in closed condition, swarms into suddenly as the bad person, and owner can press AN2 rapidly, and the AN2-1 among Fig. 2 gives " zero clearing " end one positive level of IC1, and IC1 resets, G1 ends, and IC4 gets electric conducting because of 5 pin.AN2-2 among Fig. 3 is with the SCR short circuit, and power supply is instantaneous to be full of electricity through AN2-2, J-2, D8 to C9, the IC7 upset, J adhesive, J-2 disconnect, the J-1 adhesive, and power vd D gives indoor alarm through J-1, the wireless launcher power supply, alarm is reported to the police at once, has omitted start time-delay and detection process.
By shown in Figure 2, cryptochannel mainly is made of decimal system counting/divider IC1, operational amplifier IC2, Schmidt trigger IC3.When pressing reset button AN1, the Q0 of IC1 end is flat for high point, and the A point voltage is R9, R10 partial pressure value, and its current potential is lower than the B point, is higher than the C point, E point output high level, and D point F point is low level, G point output high level.A point current potential is higher than the B point when pressing S2, and A1, A2 upset C4 rapid charge is to high level.When unclamping S2, A1, A2 are turned to initial state again, because C4 voltage can not suddenly change, make G point output negative pulse add to 13 (EN end) pin of IC1, and IC1 counts, and high level moves to the Q1 end by the Q0 end, and the like.This alarm adopts the five-digit number password, can form 30,000 multiple ciphers.When owner enters decoding, after S2, S4, S3, S1, S5 pressed successively, the Q5 end output high level of IC1, make the G1 conducting through R4, its ce knot is with IC4 control end 5 pin and ground short circuit, and IC4 is because of voltage out of hand turn-offs, and the GR2 that is arranged on the combination disk goes out, transmitting set is closed, and open the door to enter the room and do not report to the police this moment.When the password order pushes the wrong or wrong by other yard key, the A point voltage is lower than the C point voltage, the A3 upset, and F holds " zero clearing " end 15 pin one positive pulse to IC1, makes that IC1 resets, G1 continues to end, and IC4 still works, and GR2 continues bright, opens the door this moment and then reports to the police.
Beam radar detector F1, F2 among Fig. 3 forms the adjustable monitored space of 2-8 rice by the reflection feed, and its detection area can reach tens square metres, is mainly used in the mobile object at monitor window place.Be installed in magnetic control detector F3 on the doorframe and be used for preventing bad person's crime of entering the room of forcing open the door.Under the standby state of alert, F1, F2, F3 output terminal are high level, when the burglar prizes window or forces open the door intrusion, F1, F2 can detect the effractor because of moving the reflection wave that produces, F3 is pried open because of door loses magnetic field, and the contact discharges, and output terminal becomes low level by high level.No matter which detector output terminal becomes low level, all can make three Sheffer stroke gate IC5 output terminals become high level, trigger SCR through R24, IC6, R26, R25, C8, W and make its conducting.After SCR is triggered, the VDD power supply charges to C9 through SCR, J-2, D8, and when being charged to 2/3rds VDD (deducting the SCR pressure drop), the IC7 output terminal is a low level by the high level saltus step, J adhesive, J-1 adhesive, J-2 disconnect, SCR closes, C9 discharges about 60 seconds discharge offs to IC7 seven pin through R27.J-1 is closed all the time in discharge time-delay process, and light emitting diode GR3 is bright, and VDD is through J-1, R30, for G3 provides base voltage and powers to IC10 through K1-1 (when K1 is closed).Simultaneously behind D11, IC8, C12, C13 voltage regulation filtering, one the tunnel directly give wireless transmitter module IC12 power supply; Another road is tied to IC9, IC11 through the ce of G3 6V is provided stabilized voltage supply, makes the G4 conducting through R31 simultaneously, and the ce knot of G4 makes the PL end and ground short circuit of IC9, IC11.To aerial emission, its transmitting range can reach 1 kilometer to the alerting signal that IC11 prerecords (as certain unit, building, sub-district number certain other, the someone trespasses etc.) through C19, R32, R33, C20, IC12, TX1.As K1 during at closure state, the warning statement that IC9 prerecords (as catch a thief oh, catch a thief ...) give the effractor with threatening through C14, C15, IC10, C17, loudspeaker Y1, give the alarm to neighbours simultaneously.N1, N2 are respectively recording, the broadcast changeover contacts of IC9, IC11.
When owner indoor, when alarm cuts out, as find the thing that the bad person commits a crime or has other to cry for help, as shown in Figure 3, the K2 that can close connects VCC by K2-1, provide operating voltage through IC8, C12, C13 voltage regulation filtering for radio transmitter IC12, and provide operating voltage for MIC3 through R34, R35, and connect the input end of transmitter IC12 by K2-2, report a case to the security authorities or the person for help can directly report a case to the security authorities or cry for help by MIC3.
As shown in Figure 2, intercom for prevent the stranger enter the room swindle, plunder to be provided with.When the people knocks at the door or rings a doorbell, the K3 that can close, VCC forms positive and negative 6V power supply through K3, C21, C22.Y2, Y3 in this circuit be loudspeaker be again microphone.IC13, R36-R45, C23, Y2 form the differential balance bridge circuit, and the other side sends into loudspeaker from the signal that IC15 comes through C29, R37 when receiving words, is reduced into sound.According to the bridge balancing principle, this signal is the common mode input to IC13, and Y3 does not have signal sound.But the signal that is produced facing to Y2 speech amplifies through the IC13 ratio the nonequilibrium differential wave of IC13, again through the IC14 power amplification, is play by Y3 then.The principle of work of IC15, IC16 part is identical with it.By intercommunication inside and outside the door, the bad person that really admits a fault, and then open the door.
The wireless receiver principle of work:
As shown in Figure 4, the 220V civil power one the tunnel charges to DP2 through R60, GR4 after T2 step-down, D13-16 rectification, and another road is through D18, IC17 voltage stabilizing and C35, C36, C37 filtering, for receiver provides 6V stabilized voltage supply.When mains failure, storage battery DP2 powers to receiver through D17.GR4 shows for charging.
The alerting signal that IC12, TX1 launch among Fig. 3 is received by the antenna TX2 among Fig. 4, the luminous demonstration of GR5, and received signal is handled, is amplified again through IC18 and through C38, Y4 electric signal is reduced into the voice broadcast.Can change volume by regulating R61.
