Abstract

The utility model relates to a multifunctional external mounted intelligent acoustic-optic calling prompting device which is matched with a telephone and belongs to the technical field of telephonic communication. The utility model is mainly characterized in that the utility model is provided with a shell, wherein the top end of the shell is provided with an indicator lamp; the side part of the shell is provided with an acoustic-optic conversion manual switch and an input-output insertion opening connected with telephone signals and a telephone; electronic elements, such as a nand gate circuit, a time-base conversion circuit, a photocoupler, a photoresistor, a relay, etc., are arranged in the shell; the utility model is also provided with a battery mounting box, wherein the photocoupler is connected in series with a ringing circuit of the telephone; the output terminal of the photocoupler is used as the input terminal of the nand gate circuit. When the device is used, the acoustic-optic automatic conversion can be realized, and the ring disturbance in specific places and for night rest is avoided. The device is connected with a telephone jack only by using a wire and a general-purpose plug, and accordingly, the insertion is quick and convenient.

Description

The multi-functional incoming call prompting device of external intelligent acousto-optic

Technical field:

The utility model belongs to the telephonic communication technical field, is the multi-functional incoming call prompting device of a kind of external intelligent acousto-optic.

Background technology:

In family, students' dormitory, hotel, hospital, when the evening rest, telephone bell regular meeting influences people's rest, and in meeting room, language some the specific workplaces such as chamber of gathering and editing, telephone bell disturbs operate as normal again.But in the big place of noise, but telephone bell does not have suggesting effect.

Summary of the invention:

The purpose of this utility model provides a kind of acousto-optic of can realizing and changes automatically, the multi-functional incoming call prompting device of external intelligent acousto-optic of avoiding the tinkle of bells to disturb.

Realize that the technical scheme that the purpose of this utility model is taked is: provide a kind of and the matching used acousto-optic incoming call prompting of telephone set device, its main feature is: this device has a housing, the top of housing is provided with a plurality of indicator lights that colored shape is arranged that are, the housing sidepiece is provided with the hand switch and the input and output socket that is connected with telephone signal and telephone set of acousto-optic conversion, be provided with NAND gate circuit in the housing, time base change-over circuit, and photoelectrical coupler, photo resistance, electronic components such as relay, wherein, photoelectrical coupler is connected with the ringing circuit of telephone set, and the output of photoelectrical coupler is as the input of NAND gate circuit.

The multi-functional incoming call prompting device of external intelligent acousto-optic according to such scheme is made can be converted to light prompt with ring when calling at night, automatically with interruption-free people's normal rest; Can ring be converted to light prompt function by the manual mode of control by day, avoid the gather and edit the tinkle of bells of office spaces such as chamber of meeting room, language to disturb.This device only is connected with existing telephone machine transplanting of rice mouth with a line, and it is efficient and convenient, practical therefore to peg graft.

Utilize accompanying drawing to further describe enforcement of the present utility model below.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a circuit diagram of the present utility model;

Fig. 3 is the circuit diagram that the utility model inserts ringing telephone stations.

Embodiment:

Referring to Fig. 1, Fig. 2, Fig. 3, the utility model is a kind of and the matching used acousto-optic incoming call prompting of telephone set device, this device has a housing 1, the top of housing 2 is provided with indicator light 2, housing 1 sidepiece is provided with the hand switch 3 of acousto-optic conversion and the input and output socket 4,5 that is connected with telephone signal and telephone set 6, indicator light 2 can adopt one, also can adopt a plurality ofly, and is colored shape and arranges shape.Be provided with electronic components such as NAND gate circuit, time base change-over circuit and photoelectrical coupler, photo resistance, relay in the housing 1, and be provided with the battery mounting box, wherein, photoelectrical coupler is connected with the ringing circuit of telephone set, and the output of photoelectrical coupler is as the input of NAND gate circuit.This device adopts two kinds of supply power modes of alternating current-direct current, through full-wave rectification, and capacitor filtering, after 7812 voltage stabilizings, provide the stabilized power supply of 12V, utilize two inputs of NAND gate to be high level simultaneously to circuit, its output is converted to low level characteristic, has formed the change-over circuit of acousto-optic.On daytime, the resistance of photo resistance is less, NAND gate be input as low level, relay J 1, not adhesive of J2, telephone set is normal ringer then.But, if will avoid the tinkle of bells to disturb, then can ring be converted to light prompt function by hand switch 3 in the quiet office space of some specific needs.In evening, the photo resistance resistance is big, NAND gate be input as low level, relay J 1 adhesive, the ringing circuit of telephone set disconnects, when calling, the photoelectrical coupler conducting, relay J 2 adhesives make lumination of light emitting diode; Simultaneously, charge to electric capacity by resistance, when voltage reaches turnover voltage, relay J 3 adhesives, at this moment illuminating circuit and ringing circuit are worked simultaneously.Like this, promptly leave people's normal rest alone,, behind 6 ring unanswereds of incoming call light prompt, just be automatically converted to the function that the tinkle of bells, light are pointed out simultaneously again for avoiding missing phone.
