1S control end control photoelectric tube V conducting, at this moment have one from ground → C in the coil of relay K
51→ IC
1(V) → and the electric current on relay coil → ground (this electric current with inhale current opposite in direction when moving), thus relay K is discharged, return to initial condition.If at IC
2Output Q
2By " 0 " change " 1 " before, telephone set (TEL) is got machine, owing to photoelectrical coupler IC this moment
1The D control end sealed in former phone (TEL) loop, so phone (TEL) is in case get machine, photoelectrical coupler IC
1The D control end make photoelectric tube V conducting equally, relay K is discharged, and relay is in case discharge, it is normal that recover in then former phone (TEL) loop, relay tip short circuit after the photoelectrical coupler D control end that is sealed in when being relay energized is released again, so this device has no effect to the impedance of former phone (TEL) and local network etc., more than promptly be whole courses of work of this device.
Now this device operating state in all cases is summarized as follows:
1. when not having bell signal, phone TEL is in hook state, and this device also is in non operating state;
2. when phone TEL was in dialing or talking state, this device must be in non operating state;
3. bell signal is arranged, and phone TEL got machine before the several ring, and this device still is in non operating state;
4. bell signal is arranged, and phone TEL does not get machine after the several ring, and then this device is realized getting machine, raising one's voice and reply automatically;
5. this device is in when replying, raising one's voice state, if TEL gets machine, then this device discharges immediately, returns non operating state, and TEL is in talking state;
6. this device is in when replying, raising one's voice state, if TEL does not get machine always, then this device on-hook automatically behind certain hour recovers ortho states.
This device can be integrally manufactured with ordinary telephone set, is connected between phone inlet wire and the ordinary telephone set after also can making separately.The telephone set that has this device is after receiving bell signal, any artificial action needn't be arranged, can employ loud speaker certainly replys simultaneously, promptly make the other side in his receiver, hear answer statement on the one hand, and make the people by the earphone also hear the other side's calling and this machine answer statement simultaneously by loud speaker.Reply and all take the switch feed current when raising one's voice, and needn't external power supply.Because this device adopts latching relay, so only just consume some switch energy in the moment of relay changeover contact.From obtaining bell signal to loud speaker automatic-answering back device, and from beginning to reply to automatic on-hook, time length therebetween can be adjusted by potentiometer W.Reply and the soft encapsulation integrated package of loudspeaker circuit employing language (IC
4) and power amplifier (IC
5), language can be set according to application target, for example, when arranging such answer statement: " whom do you look for? please quote your name ", after the other side answers, hear near the loud speaker that the people of everything dialogue at once can both be undoubted: who this remove to connect this phone, perhaps simply do not manage it.If nobody reaches machine and answers the call, then after certain hour, just hook state is got back in this device line disconnection automatically heavily again.
After using the telephone set of this device to become the answerphone of raising one's voice automatically, can get machine automatically when receiving bell signal replys, raises one's voice, replying with telling all of the other side of oneself broadcast out by loud speaker, this just equals to state oneself for automatically loud speaker of the other side, the calling callee, this has brought greatest convenience for undoubtedly the side talked about.This telephone set is widely used in the occasion that many people share a machine, also can utilize it to reply as preposition, plays identification the other side's effect, improves the anti-tampering effect of own telephone set.
This device to telephone communication network impedance matching do not have influence.
