Description

The interface of microcomputer and phone in the smart phone

The present invention relates to a kind of computer interface, particularly the interface of microcomputer and telephone set in the smart phone.

Phone in the past, when making a phone call, telephone set must ceaselessly be handled (dialing, monitoring, judgement, processing) to telephone set by the people before connecting the called party, if this moment, phone network was in " doing " state, user's telephone set of having to handle repeatedly, repeat to do the simple work of dialing, monitoring, judgement, processing, thereby make the people spend a large amount of time and efforts, in addition owing to ceaselessly using phone to influence other this phone of call.In addition, the almost memoryless ability of present phone, or only have few memory capability, in telephone set, can not remember a large amount of information.

The object of the present invention is to provide the interface between a kind of phone and the microcomputer, thereby make telephony intelligenceization, smart phone also has following function except the function with regular phone: detect automatically, analyze, judge, the function of handling, promptly the user is as long as import an order, and smart phone just can be transferred to number, and the signaling in the detection phone network, whether connect according to the signalling analysis phone network that obtains, whether the someone for the called party, whether the called party has picked up mobile phone begins speech if answering the call, or conversed and closed, whether calling party picks up mobile phone begins conversation, or has conversed and closed, and will change different processing automatically over to according to the analysis result telephone set.Next has the function of a large amount of memories and the function of display.

Operation principle of the present invention is:

1. computer control dialing: at first CPO P1.7 output port output low level makes and drives the adhesive of triode T1 turn-on relay, the phone network signal is delivered to phone conversation input by relay, its two: CPU P1.0-P1.4 output port output control command is with gating analog switch E2, E3, make and double-tone frequency and the pulse generator keyboard input (row) and certain row conducting of universal models finally make the double-tone frequency and the pulse generator output of universal models export corresponding double-audio signal or pulse signal 2. COMPUTER DETECTION telephone ring signals; At first CPU P1.7 output port output high level ends driving triode T1, not adhesive of relay, the phone network signal is delivered to phone bell signal end by relay, by photoelectronic coupler bell signal is specially become level signal and send CPU P1.6 input port.

3. at the double-tone of universal models frequently and pulse generator output when exporting corresponding double-audio signal or pulse signal, CPU P1.5 is that output port is with output low level, to eliminate the noise signal in the phone.

4. at the telephone set duration of work, the audio signal of telephone set is sent CPU TO input port after amplifying, CPU will analyze the signal of importing, and changes different service entrances over to according to the state of its signal, promptly when phone network " hurries ", computer will be controlled phone this dialing again; When phone network was connected but also do not conversed, computer sent musical sound with control loudspeaker; When the other side picks up the phone speech, computer will be controlled musical sound and send the other side, and loud speaker will send urgency sound simultaneously, or make telephone set enter " hands-free " state, directly conversation.

This shows, by with used interface of the present invention, make smart phone and except function, also have with regular phone:

A. detect automatically, analyze, judge, the intelligence of processing, promptly as long as the user is order of input, smart phone just can be transferred to number, and whether the signaling in the detection phone network is connected according to the signalling analysis phone that obtains, and whether the called party has picked up mobile phone begins speech, whether calling party picks up mobile phone begins speech, will change different processing automatically over to according to the analysis result telephone set.As: smart phone is transferred to the telephone number of one 16 item, if phone network is connected, smart phone can send musical sound and connect to show phone network on phone network, and do not mean that closing of the circuit, have only as the other side and pick up that mobile phone is prepared for the speech or when beginning to talk, closing of the circuit, smart phone will be said " just a moment,please " to the other side or put one section music automatically this moment, to show that just a moment,please, the musical sound of the expression phone network on that the while smart phone sends stops at once, then sends nervous urgency sound, to show that the user answers the call as early as possible, in order to avoid the other side waits for that prepare for the speech in case pick up mobile phone, smart phone sends musical sound, urgency sound stops at once, and change normal conversation over to, showing telephone user's telephone number at this very moment on the display, information such as name.If the phone network line is in " doing " state, smart phone can show " the phone network line ' does ', please wait for " with automatic on-hook on the display.Wait for the several seconds to tens of seconds, smart phone can be transferred to this telephone number once more, when as if this moment this phone of External Call being arranged, smart phone dials automatic pause, can dial by display halt on the display, close when having conversed mobile phone is put back to, smart phone will dial automatically after the several seconds.

B. smart phone has the function of memory: it can store 188 16 telephone number, or more telephone number and can be made on the display by some open-and-shut behaviour it is edited, searches, revises, deletes and dials.

C: the operating state of smart phone all can and be sent different warnings by the display demonstration.
