Yet, in this internet communication pattern, phonetic entry/outputting communication unit 11 is by the analog voice signal in switch, the 3rd I/O connecting pin position 101c, the 101d input processor 101, all be sent to arithmetic element 203 to carry out the format conversion of analog voice signal and audio digital signals by control unit 202, audio digital signals after then will changing again is back to control unit 202, and further is sent to Internet connection port one 03 by pin position 101b and is resent to the Internet 15; On the contrary, all audio digital signals that 15 long-range user replys via pin position 101a from the Internet, also be sent to arithmetic element 203 to carry out the format conversion of analog voice signal and audio digital signals by detecting unit 201, analog voice signal after then will changing again is sent to control unit 202 being sent to switch 102 by the 3rd I/O connecting pin position 101c, 101d, and switch 102 sees through analog voice signal after voice connectivity port 104 will change and is sent to phonetic entry/outputting communication unit 11 and exports.
As shown in Figure 3, demonstrate a kind of structural representation of switch 102 of double-mode communication equipment 10 inside according to the embodiment of the invention.As shown in Figure 3, switch 102 comprises an amplifying unit 301, diode 302, a relay 303.Wherein, diode 302 is connected between amplifying unit 301 and the relay 303 as a protective circuit.The 3rd pin position of relay 303 and the 4th pin position and the 6th pin position and the 8th pin position are a normally closed switch respectively, and the 3rd pin position and the 6th pin position interconnect with phonetic entry/outputting communication unit 11 to see through voice connectivity port 104 by pin position 102d, 102e respectively, and the 4th pin position and the 8th pin position see through public exchanging telephone network connectivity port 105 by pin position 102f, 102g respectively and interconnect with public exchanging telephone network 16.
Under the normal power supply situation, because pin position 102c does not receive the control signal that is transmitted by processor 101g, therefore continue to keep the signal of a low level, as shown in Figure 3, amplifying unit 301 is an inverting amplifier.The signal of low level forms the signal of a high levle through after the anti-phase processing and amplifying of amplifying unit 301.The signal of this high levle may be same as the voltage of total voltage+Vcc, make and do not have potential difference between the 1st pin position of relay 303 and the 2nd pin position, in other words, open a way as forming one between the 1st pin position of relay 303 and the 2nd pin position, and then cause to produce total current 304, perhaps, the signal of this high levle also may be greater than the voltage of total voltage+Vcc, so that be parallel to the 1st pin position of relay 303 and the diode 302 between the 2nd pin position because of the forward bias voltage drop conducting, in other words, form a short circuit between the 1st pin position of relay 303 and the 2nd pin position, and then cause the flow direction of total current 304 opposite, and the relay 303 of can not flowing through with the direction of arrow shown in the legend.
Two kinds of above-mentioned situations all can't drive the action of relay 303, and in other words, the 3rd pin position of relay 303 still interconnects with the 4th pin position and the 6th pin position still interconnects with the 8th pin position.According to before described, the 3rd pin position and the 6th pin position see through voice connectivity port 104 by pin position 102d, 102e respectively and interconnect with phonetic entry/outputting communication unit 11, the 4th pin position and the 8th pin position interconnect with public exchanging telephone network 16 to see through public exchanging telephone network connectivity port 105 by pin position 102f, 102g respectively, therefore this moment, phonetic entry/outputting communication unit 21 was connected to public exchanging telephone network 16 as can be known, can directly use the public exchanging telephone network communication mode to carry out communication.
When desiring the internet usage communication mode, pin position 102c at first receives the control signal of the high levle that is transmitted by processor 101, and described control signal is sent to amplifying unit 301.Described control signal is through after the anti-phase processing and amplifying of amplifying unit 301, form one and have the control signal of low level, because the signal of described low level is less than the voltage of total voltage+Vcc, make and have a potential difference between the 1st pin position of relay 303 and the 2nd pin position, this moment, diode 302 was because of not conducting of reverse bias, and then cause total current 304 as the flow direction shown in the legend, promptly high potential flows to electronegative potential, and by the 1st pin bit stream of relay 303 to the 2nd pin position.
When total current 304 is flowed through the 1st pin position of relay 303 and the 2nd pin position, effect because of electromagnetic induction (induction law), so that produce magnetic field around being arranged at coil 305 between the 1st pin position and the 2nd pin position, and then cause the 3rd pin position to be adsorbed to interconnecting and the 6th pin position is adsorbed to the 7th pin position and interconnects with the 5th pin position.Wherein the 5th pin position and the 7th pin position interconnect with the Internet 15 through processor and Internet connection port one 03 by pin position 102a, 102b respectively, according to before described, the 3rd pin position and the 6th pin position see through voice connectivity port 104 by pin position 102d, 102e respectively and interconnect with phonetic entry/outputting communication unit 11, and therefore phonetic entry this moment as can be known/outputting communication unit 11 can carry out communication by the internet usage communication mode.
Yet, if under the civil power powering-off state, because the 3rd pin position of relay 303 and the 4th pin position and the 6th pin position and the 8th pin position are a normally closed switch respectively, therefore this moment, the 3rd pin position still interconnected with the 4th pin position and the 6th pin position still interconnects with the 8th pin position, in other words, phonetic entry/outputting communication unit 11 still is connected to public exchanging telephone network connectivity port 105, and, make phonetic entry/outputting communication unit 11 still can use the public exchanging telephone network communication mode to carry out communication by 48 volt feed pressure and 25 milliamperes of supply currents that telecommunications company provided.
As shown in Figure 4, demonstrate a kind of according to the embodiment of the invention the hardware configuration schematic diagram of processor 101 of double-mode communication equipment 10, comprise a Digital Signal Processing (Digital Signal Process, DSP), itself and internal memory 107, voice connectivity port 104, Internet connection port one 03, a display unit 401 interconnect.
