Embodiment
Below in conjunction with accompanying drawing the utility model preferred embodiment is further described:
Embodiment one:
With reference to Fig. 1 and 2, provided a kind of PC telephone device.Among the figure, telephone device 1 is provided with two telephone line interfaces, i.e. telephone line interface 11 and telephone line interface 12; Be provided with a usb 13.The PC telephone device is made up of shell and internal circuit on the whole.As shown in Figure 2, circuit part, it comprises processor module, USB driver module, incoming call identification module, dial-up circuit module, conditioning circuit module.Wherein, telephone line interface 11 and telephone line interface 12 can directly be connected in parallel, processor module is general to adopt CPU, RAM, ROM, timer conter and multiple I/O interface with computer to be integrated in micro-control unit on a slice chip (MCU), as adopting single-chip microcomputers such as 51 series, AVR series, ARM series as control chip.The USB driver module is the intermediate module that connects telephone device and PC, its realization be level adapted, data buffering function between device and the computer, the USB driver module directly is connected with processor module.The incoming call identification module is to discern bring in electric number from telecommunications, and it directly is connected with MCU and institute's identification caller ID is sent to PC by processor module and USB driver module, for incoming call is prevented fires, the shielding of particular number provides hardware supports.The incoming call identification module can adopt the IC (as shown in Figure 3, for this IC packing forms) of HT9032 series during concrete enforcement.Dial-up circuit module connection processing device module also is connected with telephone wire by conditioning circuit module and realizes the dialing instruction of sending by PC and to carry out dial-up operation according to this number.The dial-up circuit module can adopt the IC of HT9200 series, as shown in Figure 4, is the encapsulating structure of this IC.Conditioning circuit module is connected between phone line end and the processor module, realization is converted into voice signal (being the PAC circuit function) from the signal of telecommunication of telephone wire, because most MCU has the A/D module, so the speech simulation signal that separates from conditioning circuit module can directly be imported MCU and carry out discretization and become digital signal with by the PC storage, conditioning circuit module also is embodied as the operating voltage that the voltage transitions from telephone wire becomes MCU to be fit in addition, the effect of performance level conversion is for dial module realizes dialing performance auxiliary dial function etc.Because dial-up circuit module, conditioning circuit module have had the difference of the connection of ready-made circuit structure and various IC and MCU according to series or model, circuit structure also changes thereupon, actually can carry out circuit connection according to the explanation of each IC and MCU, the utility model is not described one by one.
With reference to figure 1, when the utility model used, the telephone line interface 11 of PC telephone device was connected with telecommunication apparatus terminal 3, and telephone line interface 12 is connected with ordinary telephone set 4; Usb 13 is connected with the USB interface of PC terminal 2.
Operation principle to the PC telephone device is further described below:
One. commonsense method is made a phone call
The PC telephone device connects according to the structure of Fig. 1, and promptly the telephone line interface 11 of PC telephone device is connected with telecommunication apparatus terminal 3, and telephone line interface 12 is connected with ordinary telephone set 4; Usb 13 can be connected with the USB interface of PC terminal 2, also can not connect; The user uses ordinary telephone set to dial, and dialing signal directly exports the telecommunications end to by telephone line interface 11 after arriving telephone line interface 12, and must not handle through the device internal circuit; The user uses the microphone of ordinary telephone set and receiver to converse.
Two. use PC to dial, use ordinary telephone set to converse
The usb 13 of PC telephone device must be connected with the USB interface of PC terminal, and the user chooses one or more numbers at address list etc. and carries out dial-up operation under the software of PC is supported; The dialing instruction of PC and number arrive processor module through the USB driver module, the processor module of PC telephone device responds this instruction, and carry out internal processes output dialing signal to the dial-up circuit module, the dial-up circuit module directly or through behind the conditioning circuit module is carried out dial-up; The user picks up the microphone of ordinary telephone set and converses.
Three .PC machines are recorded
The usb 13 of PC telephone device must be connected with the USB interface of PC terminal, the user uses in the ordinary telephone set communication process, the PC telephone device detects and intercepts the signal of telecommunication of telephone wire, carry out speech Separation by conditioning circuit module, and after the A/D interface by processor self carries out analog-to-digital conversion, will preserve by digital data transmission to the PC of sound in the process.Under software was supported, PC can reduce to the voice data of preserving.Because the memory space of PC is bigger, so with respect to common smart phone, this device can be realized the mass memory of conversation voice audio data.
The four .PC machines fire-proof function of sending a telegram here
The usb 13 of PC telephone device must be connected with the USB interface of PC terminal, the incoming call detection module of PC telephone device, detect caller ID, if it is identical with the computer preset number, then install automatic-answering back device and hang up (before plain old telephone shake bell, finish one and reply and hang up operation) rapidly, reach the purpose of advoiding harassing and wrecking.
Five .PC machines add incoming calls record, address list renewal, automatic-answering back device automatically
The incoming call detection module of PC telephone device detects caller ID and transfers to PC through processing module and USB driver module, and PC if be new digit, then is added into address list automatically under the support of software; And form historical message registration inventory etc.; In addition under computer software must be supported, can record the audio frequency of automatic-answering back device, when detecting incoming call for the setting number, automatically will transfer the processor of this audio file output, and be converted to the signal of telecommunication converse automatically (the big environment of demand that can be fit to some fixedly voice service business) as for the PC telephone device.
Six. other function
Under the support of PC terminal software, the combination of PC and PC telephone device can be developed various specific functions.
The power supply of PC telephone device:
Be not connected with PC or PC is in off-mode at the PC telephone device, device is directly by phone-line-powered; Be connected with PC and when being subjected to PC control, based on phone-line-powered, the USB power supply is auxilliary.When removing sound-recording function, under other situation, the direct power supply of telephone wire can be satisfied device operation demand fully.
Embodiment two:
