Abstract

The utility model relates to a telephone remote control device of an electronic lock with simple structure and good functional performance. the utility model has the technical proposal that: the telephone remote control device of the electronic lock is provided with a telephone line socket and is characterized in that the lead wire of the telephone line socket can be connected to a telephone interface module for ringing detection, the signal output end of the telephone interface module is connected with a singlechip, the signal output end of the singlechip is connected with an executive circuit for opening the electronic lock, and the singlechip is also connected with a password memory chip externally. The utility model adopts parts such as the singlechip and the password memory chip to effectively simplify the circuit structure and meanwhile improving the functional performance.

Description

The remote controlling device for telephone of electronic lock

Technical field:

The utility model relates to a kind of remote controlling device for telephone of electronic lock.

Background technology:

Electronic lock much all is to control by remote controller at present, when having electricity or lose, remote controller can't not open electronic lock, remote-controlled lock of telephone can effectively address this problem, with the immediate prior art of the utility model be that the patent No. is 20032013197.2 patent name remote-controlled lock of telephone patents, but the circuit structure of this patent is comparatively complicated, and functional performance is not ideal enough.

The utility model content: the technical problems to be solved in the utility model provides a kind of remote controlling device for telephone of electronic lock, and it is simple in structure, and functional performance is good.Technical scheme: a kind of remote controlling device for telephone of electronic lock, has telephone line socket, it is characterized in that: the lead-in wire of telephone line socket connects and can carry out the telephony interface module that ring detects, the signal output part of telephony interface module connects single-chip microcomputer, the signal output part of single-chip microcomputer connects the executive circuit of unlocking electronic lock, and single-chip microcomputer also is circumscribed with the password storage chip.Beneficial effect: because the utility model has adopted parts such as single-chip microcomputer, password storage chip, simplify circuit structure effectively, improve functional performance simultaneously.

Description of drawings:

Accompanying drawing is circuit theory diagrams of the present utility model.

The specific embodiment:

As shown in the figure, the lead-in wire of telephone line socket J 2 connects and can carry out the telephony interface module U1 that ring detects, the signal output part of telephony interface module U1 meets single-chip microcomputer U2, and the signal output part of single-chip microcomputer connects the executive circuit of unlocking electronic lock, and single-chip microcomputer also is circumscribed with password storage chip U3.

During enforcement, the telephony interface module is for carrying out the telephony interface module that bell signal detection and dtmf signal receive.The executive circuit of unlocking electronic lock is, the base stage of switching tube BG connects the signal output part of single-chip microcomputer U2 through resistance R 2, LED, and the colelctor electrode of switching tube connects the relay J 1 that the control electronic lock is opened.Between telephone line socket and the telephony interface module, be serially connected with piezo-resistance R1, the effect of piezo-resistance R1 is to be used for protecting the remote telephone circuit to avoid being subjected on the telephone wire burst high pressure or thunderbolt to bring out the surging destruction circuit that is produced.Also be serially connected with voltage-stabiliser tube Z1, Z2 and capacitor C between telephone line socket and the telephony interface module.

When calling ring, the interchange 25Hz/90V ringing voltage that process telephone line socket J2 enters, through voltage-stabiliser tube Z1, the Z2 step-down, capacitor C isolated DC electricity is delivered to telephony interface module U1, the ring detecting circuit of telephony interface module U1 inside is handled signal, export the ring detection signal to single-chip microcomputer by telephony interface module U1, after single-chip microcomputer detects 6 bell signals, U1 makes the phone off-hook by single-chip microcomputer U2 control telephony interface module, this moment, the captaincy inputed password on phone, and the DTMF receiving element circuit demodulation output DTMF useful signal of telephony interface module U1 inside is to single-chip microcomputer U2.Single-chip microcomputer U2 reads password from password storage chip U3, it is right to carry out cryptographic core, the voice amplifying unit circuit of single-chip microcomputer U2 control telephony interface module U1 inside, if password correctly send prompt tone for " too " sound, the incorrect warning of sending is " ticking " sound.When cryptographic core to after passing through, the calling party is by the telephone key-press transmitting order to lower levels, Single-chip Controlling is carried out corresponding operating.

When order when unblanking, single-chip microcomputer U2 export high level, makes switching tube BG saturation conduction, relay J 1 adhesive, the action of corresponding interlock contact is locked connected stealth by electronic lock socket J3 and is opened.When order when new password is set, input password twice, if twice password is identical, then with new password storage to password storage chip U3, export prompt tone simultaneously and be " too "; If twice password is identical, carry out the on-hook operation after sending the warning of " ticking ".When order was on-hook, U1 made the phone on-hook by single-chip microcomputer U2 control telephony interface module, finishes once-through operation.
