As shown in the figure, described alarm is mainly deployed troops on garrison duty by D.C. regulated power supply A, wireless remote control, and switch B, anti-theft warning circuit C and siren drive and holding circuit D forms.

Be described in detail principle of work of the present utility model below in conjunction with accompanying drawing 6.

1, D.C. regulated power supply and back-up source: 220 volts of AC power are imported by socket CZ, F1 is connected to primary through insurance, exchange by secondary output 16.5V after the transformation, again after D1-D4 rectification, C1 filtering, add to 1 pin of stabilivolt 7812, three diodes of forward serial connection raise its current potential 2.1 volts between 7812 2 pin and the ground, such 7812 3 pin have just obtained 14.1 volts voltage, and through C2 filtering once more.This voltage is reduced to 13.4 volts behind D8, add to battery anode by R3, and to battery-powered, R3 is a current-limiting resistance.Simultaneously, this voltage provides operating voltage to other parts.When exchanging power failure, battery anode is powered to each several part through D9.Here utilized two 6 volts of batteries serial connections dexterously, exported 6 volts of required power supplys of siren in wireless receiver and the machine from the junction of two batteries.6 volts of mu balanced circuits have been saved.

2, burglar alarm part: this part is made up of burglar alarm probe M and testing circuit.The window comparator that testing circuit is made up of operational amplifier UI:C and UI:D, R7, the R8, the R9 that are connected between power supply and the ground provide bound reference voltage VA1 and VB1 for comparer, R10 and R11 are the pull-up resistors of UI:C and UI:D output terminal, and D10 and D11 are with the output VoD of the output VoC of UI:C and UI:D mutually or obtain the final output Vo1 of comparer.The operating voltage of burglar alarm probe is 12V, exports in the relay mode.After the energized, relay is for attracting state, so the normally closed contact of relay and normally opened contact are opposite when here using under the normal condition.When using the normally closed contact of relay, after the alarm probe energising, keep normally open under the normal condition; should and meet protective resistance RM at the two ends, contact, just obtain alarm probe output voltage V i1 just often after R5 and the RM dividing potential drop, at this moment VA1＞Vi1＞VB1; when alarm probe is reported to the police, KM closure, Vi1=OV; be Vi1＜VB1; then VoD exports high level, and causes Vo1 output high level, if at this moment deploy troops on garrison duty switch Q1 conducting; Vo1 just can pass through Q3 adhesive J1, starts siren and reports to the police.When the circuit of alarm probe breaks down, as short circuit appears, Vi1=oV then, and Vi1＜VB1, then VoD equals high level, and Vo1 is uprised, and drives siren and reports to the police.When open circuit appears in circuit, the Vi1=+12 volt, Vi1＞VA1, VoC exports high level, and Vo1 is uprised, and drives siren and reports to the police.In a word, have only normal when the warning loop and the situation that not have to report to the police under, Vo1 just is a low level, the shutoff siren; As long as occur reporting to the police or line fault, Vo1 will export high electric level, drive siren and report to the police.

3, the wireless remote control robbing-proof alarm and the switch of deploying troops on garrison duty: this part is made up of transmitter, receiver and related circuit.Be used for realizing the operation of deploying troops on garrison duty, withdraw a garrison of robbing-proof alarm and antitheft loop.Transmitter is made up of a, b, c, d four operating keys, coding circuit and high frequency transmission circuits, is prior art; Receiver is made up of high frequency receiving circuit and decoding circuit, is prior art; Receiver has and a, b, the corresponding output line Da of c, d, Db, Dc, Dd, and the Code And Decode circuit has corresponding eight address wires that can artificially be provided with.High-frequency emission and receiving circuit are to be used for sending the coding of coding circuit to decoding circuit.When having only address code when the coding/decoding circuit identical, output line Da-Dd is with output and a, b, c, the corresponding state of d button.In a word, every cover telepilot all has independently corresponding relation, can not interfere with each other, the a of transmitter, b two keys are used for robbing-proof alarm in this alarm, meet when plundering, press any key of a, b, then on output line Da, the Db of receiver, will export high level accordingly, through diode D13, D14 mutually or after, make Vo3 output high level, drive the Q3 conducting, make relay J 1 adhesive, the J1-1 closure, siren JD connects 12 volts of power supply alarmings.When needs are removed warning, press the d key of telepilot, DA, the DB of receiver become low level, the Vo3 step-down, Q3 is turned off, and relay J 1 is decontroled, and siren is closed, and stops pronunciation.When needs are deployed troops on garrison duty to antitheft loop, press the C key of telepilot, the DC output high level of receptacle, be added to the base stage of Q2 through D15, R13, make the Q2 conducting, cause the Q1 conducting, thereby make V01 deliver to the V03 end through Q1, so just, the output V01 of burglar alarm has been received the base stage of siren driving circuit Q3,, can start siren by Q3 and J1 and report to the police if any theft alarm or line fault.In the time of need withdrawing a garrison, press the d key of telepilot, the DC step-down of receiver turn-offs Q2, causes Q1 to turn-off, and V01 and V03 disconnect, and at this moment the state of antitheft loop will no longer influence the state of siren.In other words, antitheft loop is in the state of withdrawing a garrison, and is inoperative to reporting to the police.

4 sirens drive and holding circuit: siren drives to be made up of Q3 and J1.V03 was a high level when warning was arranged, be added to the Q3 base stage through R14 and make the Q3 conducting, and relay J 1 adhesive, J1-1 is logical, and-12V is added to JD and goes up pronunciation.The siren holding circuit is made up of siren in wireline inspection circuit and the machine.The window comparator that testing circuit is made up of U1:A and U1:B, R20, R21, R22 are serially connected between power supply and the ground, and for comparer provides bound reference voltage VA2 and VB2, R23 and R24 are the pull-up resistors of comparer.When alarm was in waiting state, relay J 1 was in off-state, and normally closed contact J1-2 is in conducting state, and the positive pole of JD is received R17, and R18, R17 and siren internal resistance are serially connected with between power supply and the ground.After dividing potential drop, obtain V12, when the siren circuit just often, VA2＞Vi2＞VB2, VoA and VoB are low level, Vo2 is a low level, Q4 ends, siren circuit KD-9561 goes up no-voltage in the machine, so YD is mute.When the siren circuit breaks down,, cause VoB to uprise as short circuit: Vi2＜VB2; As open circuit: Vi2＞VA2, cause VoA to uprise, VoA and VoB through D17, D18 mutually or Vo2, as long as VoA and VoB any uprise, Vo2 promptly uprises, and makes the Q4 conducting ,+6 volts voltages are added on the KD-9561 through D16, Q4, produce police whistle sound, YD pronounces by the Q5 driving.

The utility model has following several characteristics:

1, siren route protection function: siren is to report to the police to use electroacoustic apparatus. The siren circuit is under the supervision of siren testing circuit in the alarm all the time. In case be short-circuited with open circuit, testing circuit detect immediately and the output signal driving machine in alarming horn report to the police.

2, warning Loop Protection function: anti-theft probe such as DT420, DT450 etc. that the warning loop connects standard can realize anti-theft alarm function. The warning loop has the fault self-checking function, no matter is short-circuited in the circuit or opens circuit, and siren all can send alarm signal.

3, Digiplex: can carry, overcome the shortcoming that the floatless switch alarm equipment alarm is subjected to position limit.

4, non-maintaining rechargeable battery being arranged in the machine, is exactly that power supply is destroyed or have a power failure and still can report to the police.

The utility model is simple in structure, be convenient to make, working stability, is a kind of desirable anti-robbery anti-theft warning device.
