In order to produce continual alerting signal and to prolong one section time of fire alarming behind the door when closing, being serially connected in to design between trigger circuit and the executive circuit has the self-insurance delay circuit that is made of electric capacity and resistance.

For improving the tonequality of doorbell signal, being serially connected between the base stage of electronic switching tube and the ground also, design has capacitor filter.

For convenience, also be connected to the indoor auxiliary control circuit of forming by positioning switch at the two ends of door and window multiple spot control circuit.

Whole device is by the 6V dry cell power supply.

This device has following function:

1, the security settings of going out; 2. illegal open alarm;

3. warning self-insurance time-delay; 4. password is removed;

5. as doorbell; 6. indoor auxiliary setting;

7. tamper-proof; 8. neighbours' joint defence.

In sum, the utility model is the intelligent electronic device that integrates modern electronic technologies such as information stores and memory, state recognition, numerical coding, cipher control, have strong security, reliability height, characteristics such as tamper-proof, power consumptive province, simple in structure, a tractor serves several purposes.

Accompanying drawing provides the embodiment of this device, and its principle of work is illustrated in conjunction with the accompanying drawings, wherein:

Fig. 1 is the block scheme of embodiment.

Fig. 2 is the electrical schematic diagram of embodiment.

Whole device is made up of password generative circuit (1), alarm control circuit (2), circuit (3), doorbell control circuit (4), doorbell signal circuit (5) and signal amplification circuit (6) six parts.

Password generative circuit (1) comprises by four RS triggering integrated circuit (IC) 1, is attempted by four key letter K1～K4 between four reset terminals of IC1 and the positive source and is serially connected in the coding circuit (7) that four resistance R 1～R4 between four reset terminals and the ground form respectively, also comprises the pseudo-decoding circuit of being made up of the pseudo-code key K5～K8 that is attempted by between IC1 reset terminal S1 and the resistance R 5 (8); Alarm control circuit (2) comprise the resistance R 6, R7 and diode D1, the D2 that are serially connected in IC1 output terminal Q4 and connect, trigger circuit (9) that triode V1 forms, be serially connected in door, the window multiple spot control circuit of forming by tandem tap group KC1～KCN between trigger circuit (9) and the ground (10) and be serially connected in positive source with T type between the executive circuit (11) and warning music integrated circuit (IC) 2 between the control executive circuit (11) of triode V2 formation; Warning circuit (3) is formed (12) by warning music integrated circuit (IC) 2 and resistance R 9 between emitter-base bandgap grading that is serially connected in triode V2 and the ground; Doorbell control circuit (4) is formed (13) by the K switch B and resistance R 11, R12, the triode V5 that are serially connected between positive source and the ding-dong music integrated circuit; Doorbell signal circuit (5) is made up of ding-dong music integrated circuit IC3 and diode D4; Signal amplification circuit (6) comprises that composite amplifier and loudspeaker SP, external speaker jack CK that resistance R 10 and V3, V4 form form (15).

In the circuit, C1, C8 constitute warning self-insurance delay circuit (16), and C2 is capacitor filter (17), and KA is indoor auxiliary control circuit (18).

The principle of work of whole device is illustrated in conjunction with its function:

1. go out the security settings owner when going out, the indoor auxiliary K switch A that is provided with disconnected, after shutting up the door carefully again by among pseudo-code key K5～K8 any one this moment rest-set flip-flop by order set, Q4 exports high level.But because KC is closed, switching tube V2 base stage is that low level is ended, thereby the alarm free signal.

2. illegal open alarm is if there is the people illegally to open the door, then because KC disconnects, and the V2 base stage is high level and conducting, and IC2 gets electrical output signal, this signal through V3, V4 amplify promote loudspeaker SP send loud and clear " toot " sound.

3. the warning self-insurance is delayed time this device in case after reporting to the police, because self-insurance capacitor C 1 is recharged rapidly, triode V2 keeps conducting always, so as long as the door opener does not know password, even door is shut again, because the discharge process of C1 just stops after a period of time of also will delaying time reporting to the police.

4. press password and remove warning owner Lai Jiashi, no matter be under which kind of state, as long as press key letter K1～K4 successively, then four rest-set flip-flops all reset, the Q4 output low level, D1, D2 conducting, the C1 discharge off, the V1 base stage is a low level, thereby after opening the door again, although KC disconnects, V1, V2 all can conductings, do not report to the police.

5. when coming to visit as the doorbell guest, by the doorbell key KB that indicates " bell " word, the V5 conducting, IC3 gets electric, sends " ding-dong " signal and makes the loudspeaker sounding through V3, V4 amplification, and at this moment, because the hypotensive effect of R11 and V5, IC3 obtains the voltage about 3V.

6. indoor assisting is provided with KA for switch is set.When KA was closed, KC was by short circuit, thereby no matter Q4 exports high level or low level, does not all report to the police, and owner both can freely come in and go out, and also can prevent the wrong report that causes because of random button.Have only when KA disconnects, could recover the warning stand-by state.

7. tamper-proof as the people destroy keyboard or cut off keyboard and main frame between on line the time because the existence of R6, main frame is still reported to the police when opening the door.

Neighbours' joint defence if on jack CK by a loudspeaker to the neighbour's, then illegally opening the door as the people causes that the neighbour's listens to chimes of doom when reporting to the police, to reach the purpose of joint defence.

In the present embodiment, the main components and parts of circuit are selected as follows:

IC1 four rest-set flip-flop CD4043

IC2 music-integrating block KD1500

V1～V5 triode 9013

D1～D4 diode 1N4148

K1～K9 touches button

SP loudspeaker 8 Ω, 0.5W
