One checks the password step, and this embedded CPU is compared operator's data in this mnemon so that operator's the legal right to use really; And
One determination step that whether networks, so, when networking successfully, the module function directly enters waits for the network dial step, with input listener's telephone number, or when signal does not enter networking function, then see through the direct remote control function of surfing the Net of above-mentioned radio telephone module by signal sending end.
Description of drawings
Other advantage of the present invention or creation purpose will be done exemplary illustrated with embodiment, and be aided with accompanying drawing to promote understanding, and this only is exemplary and unrestricted certainly, any functional structure change, alternative or equivalence constitutes with method all should be interpreted as extension of the present invention, wherein
Fig. 1 a is a network phone system schematic flow sheet commonly used;
Fig. 1 b is according to one of the present invention embodiment schematic flow sheet;
Fig. 2 is a phone calcspar of the present invention;
Fig. 3 is a program circuit calcspar of the present invention.
Embodiment
At first see also shown in Fig. 1 a and Fig. 1 b, instruct the use of the driving wireless network telephone of a program mode but its main difference is the present invention.Core technology and development of technologies about the networking telephone have been done necessary explanation in the front, only partly do sufficient explanation with regard to feature of the present invention or main improvement at this.
See also shown in Fig. 2,3, utilize a network modules to be responsible for and extraneous internetwork both-way communication in fact, one radio telephone module be responsible for and extraneous wireless phone between voice bidirectional communication and connection signal, one analog/digital conversion unit will be received from this radio telephone module analog signal of voice and convert digital signal to, or convert the digital signal of this network modules of be received to analog signal and pass in this telephone set; One compression/decompression unit is used for the digital signal of above-mentioned analog/digital conversion unit output is compressed processing, or passes in above-mentioned analog/digital conversion unit after the compression digital signal that is received decompressed; One mnemon writes down required program data and temporary data; An and embedded CPU, be used for controlling this network modules, this radio telephone module, this analog/digital conversion unit, this compression/decompression unit and this mnemon, the voice analog signal that this embedded CPU makes this radio telephone module be received, become digital signal via this analog/digital conversion cell translation, compressed processing via this compression/decompression unit again, seeing through this network modules sends out, this embedded CPU makes this network modules received digital signal, after being decompressed via this compression/decompression unit, become analog signal via this analog/digital conversion cell translation again, see through this radio telephone module and send out.
It mainly is to utilize the built-in radio telephone module of the present invention to start the telecommunication signal, and utilizes embedded CPU (processor) to carry out the processing and the control of voice information, and its control flow will and be aided with following explanation with Fig. 3 program circuit and obtain embodying.
At first, work as electric power starting, system enters the S1 autodiagnosis, if invalid, system can oneself repeat autodiagnosis, if normally then enter S2 system start-up, in the time of normal, system can directly enter the S3 holding state; At this moment, system must connect setting key earlier and finish the default program that S5 waits for dialing before presenting holding state, allowed system present the holding state of S3 again; Because system mode in the time of the S3 holding state wireless startup module with make system being connected of radiophone when wireless sender feed signals is given receiver, this module part can detect the signal of receiving and enter the S4 wireless module and start.
Wireless module setting up procedure S4 at first detects the inspection password, check whether carry out detection signal after errorless networks, if networking function success, the module functional mechanism directly enters S9 and waits for dialing, telephone number with input the other side, when if signal does not enter networking function, then enter before the S5, by signal sending end by the direct remote control function of surfing the Net of wireless module, at this moment, if successful connection then system enters S6 dials up on the telephone, successfully whether start in function of surfing the Net and to represent with S7, voice system can be informed " please after a while " prompting when function of surfing the Net successfully starts, if failure (for example, after continuous three failures) system can judge that yes returns the holding state of S3, or judge into No then system advance to before the S6, this moment, system can require repetition S5 step, if surf the Net successfully this moment, system sends signal, the wireless phone that three times toot sound prompting person informs Transmitter Zone for example appears, if failure then enters the automatic off-line machine dialing of S10 timing, and then to the automatic off-line of S11 judgement becoming.
When the expression of system prompt sound success, system then directly enters S9 and treats dialing status, if wait for that dial mechanism is idle, for example three minutes, system can Auto-Sensing to and enter the S10 function and judge yes and enter S11 and automatic off-line along with meeting.
Again, dialing is finished when system, and after system's judgement was errorless, system can proceed to normal call function state and enter the normal voice conversation.
One of the present invention is characterised in that the voice messaging between this wireless network module and this CPU is handled and control comprises: a self-examination step, to check whether fault of this above-mentioned network modules, this radio telephone module, this analog/digital conversion unit, this compression/decompression unit, this mnemon and this embedded CPU; One networking step, this embedded CPU makes this network modules connect extraneous network; One checks the password step, and this embedded CPU is compared operator's data in this mnemon so that operator's the legal right to use really; And the determination step that whether networks, so, when networking successfully, the module function directly enters waits for the network dial step, with input listener's telephone number, or when signal does not enter networking function, then see through the direct remote control function of surfing the Net of above-mentioned radio telephone module by signal sending end.
Because the present invention utilizes wireless module to do system's interface, and utilize embedded central processing unit to do flow processing and control, therefore but basically applicable to the intercom of general radio-type, radio telephone program wireless remote control intercom, infrared ray digital remote control Audio Controller, mobile telephone telephone bandset etc., but it cooperates derive at least advantage of following direct derivation of technological means of hardware interface with the software programming:
1, main frame belongs to wired connection type fixed telephone, need not carry main frame and is connected to other telephone set if will use elsewhere, and mobility is good.
2, utilize wireless phone to dial and connect and be fixed on indoor network machine line, improve its convenience.
3, because transmitting audio signal interface module is applicable to wireless transmission, its extended function also constantly strengthens its extendibility because of the exploitation of new science and technology part.
In sum, positive application case desirable possible shortcoming to the greatest extent before the present invention effectively solves provides the function of an initiative simultaneously, should be to meet every legal important document, now proposes application for a patent for invention in accordance with the law.
