Description

The automatic paging burglar alarm

The utility model relates to a kind of electronic alarm device, particularly the automatic paging burglar alarm.

Existing electronic alarm generally all is to utilize single-chip microcomputer and interface circuit and various transducer or probe wired connection, for fear of the problem that owner enters the room and also reports to the police, they generally adopt the mode of the back delayed alarm of entering the room or adopt the mode of door lock and alarm host machine wired connection.Its defective mainly contains: the microcomputer development software cost is higher; Simultaneously, inconvenience is not only used, installed to wired connection, and easily found and destroy by the burglar, moreover this electronic alarm device can't be informed alert rapidly owner and entrance guard, security personnel outside.

The purpose of this utility model is to provide the simple relatively and automatic paging burglar alarm that can rapidly alert be informed owner or entrance guard, security personnel of a kind of circuit structure to overcome above-mentioned defective.

The automatic paging burglar alarm that the utility model proposes mainly is made up of remote controller, radio trigger control circuit, radio reception control circuit, automatic paging warning circuit.Remote controller is provided with " warning " and " releasing " two states, the radio trigger control circuit triggers controller by transducer or probe and radio and constitutes, transducer or probe output trigger controller with radio and link to each other, be triggered if any transducer or probe, then radio triggers the controller transmitted radio signal and gives the radio reception control circuit, simultaneously, remote controller sends " warning " or " releasing " signal and gives the radio reception control circuit.The automatic paging warning circuit by trigger, single stabilization delay circuit, alarm, blocking oscillator A, delay circuit, dislodging machine circuit, blocking oscillator B, redial circuit, telephone set dial-up circuit etc. and constitute.The output of radio reception control circuit links to each other with the control end of single stabilization delay circuit by trigger, the operating state of control single stabilization delay circuit, another output links to each other by the trigger end of single stabilization delay circuit with alarm and blocking oscillator A, the output of blocking oscillator A links to each other with dislodging machine circuit and delay circuit respectively, the output of delay circuit links to each other with the input of blocking oscillator B, the output of blocking oscillator B redials circuit input end with telephone set and is connected, and telephone set redials circuit and links to each other with outside line by the dislodging machine circuit.

During use, can utilize beeper that dialing keyboard setting or change report to the police number and code.After the remote controller that owner carries was pressed " releasing " key, the radio reception control circuit forbade that by trigger single stabilization delay circuit triggers after receiving " releasing " signal.After remote controller is pressed " warning " key, the radio reception control circuit allows single stabilization delay circuit to trigger by trigger after receiving " warning " signal, after this, be triggered if any transducer or probe, radio triggers the controller transmitted radio signal, after receiving, the radio reception control circuit triggers single stabilization delay circuit work immediately, the alarm siren rings, simultaneously, blocking oscillator A work output high level, make the dislodging machine circuit be in off hook state, in addition, the high level of blocking oscillator A output provides working power for blocking oscillator B after the delay circuit time-delay, blocking oscillator B output high level makes telephone set redial circuit working, promptly redial the called number of prior storage, be transmitted to beeper, thereby realize automatic paging by transmitting station by outside line.

The utility model has adopted the wireless remotecontrol triggering technique of encoding and decoding, utilizes telephone set dialing chip, and monostable trigger-action circuit and oscillator are realized the repeatedly paging automatically of onsite alarming and beeper, have solved the defective that existing alarm can't be informed alert rapidly owner.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is a circuit structure block diagram of the present utility model.

Fig. 2 is automatic paging warning circuit figure of the present utility model.

With reference to Fig. 1, Fig. 2, use double-point double-throw switch, make two normally opened contact short circuits of double-contact relay J, i.e. 1 and 3,4 and 6 short circuits simultaneously, this moment, the VD terminal voltage of IC5 rose, HKS ground connection, owner can be provided with or change the beeper number and the code of warning by keyboard.After owner is by the remote controller setting " releasing " of carrying.This signal is after the decoding of radio reception control circuit, the Q3 conducting triggers the R-S trigger of being made up of two NAND gate of IC1 (CD4011), make 4 pin of IC1 be output as low level, 4 pin that are single stabilization delay circuit IC2 (555) also are low level, even thereby transducer or probe are triggered, IC2 does not work yet, and promptly can not report to the police.On the contrary, after owner presses " warning " key by remote controller, the Q2 conducting, the 4 pin output high level of IC1,4 pin that also are IC2 are high level, if after this transducer or probe are triggered, radio triggers controller and launches encoded radio signal immediately, after the decoding of radio reception controller is correct, the Q1 conducting triggers monostable trigger-action circuit IC2 work, the 3 pin output high level Q4 conducting of IC2, alarm equipment alarm, blocking oscillator AIC3 vibrates immediately simultaneously, be about 25 seconds cycle of oscillation, accounted for 20 seconds when wherein high level is exported, Q5 turn-on relay J1 adhesive is similar to the telephone set off-hook time during this period of time; Low level output is about 5 seconds, Q5 ends, relay J 1 discharges, be similar to the telephone set on-hook, (J1 is a double-contact relay, the HKS ground connection of IC5 during adhesive) 3 pin of IC3 output high level after the capacitance-resistance time-delay to blocking oscillator BIC4 (555), the IC4 vibration, be 20 seconds cycle of oscillation, and wherein the 3 pin high level output times of IC4 accounted for photocoupler work 0.5 second, R4, the approximate short circuit in C4 two ends, be similar to manually strong by once redialing, the beeper automatic station number of promptly transfering and originally being stored in the warning among the IC5 (91210), beeper number and alarm sign indicating number.The dtmf signal that (the 3 pin output low levels of IC3 are 19.5 seconds, be similar to artificial off-hook and by the time of waiting for the stored-program control exchange echo behind the redial key) transferred to after Q6 amplifies by polar protective circuit to outside line.

Longer because of monostable IC2 delay time, thereby can realize automatically repeatedly calling alarm.

In addition, during non-alarm condition, outside line 10M resistance all provides power supply to IC5, thereby the paging number of the original warning that is provided with of owner is all stored.
