Abstract
The utility model relates to an information telephone with a liquid-crystal display, which is mainly composed of the existing telephone dial keyboard and a circuit board which is installed in the existing telephone case or an exclusive use housing and is composed of a signal receiving and sending device, a data memory, a central processing unit and a liquid crystal display.. The utility model not only keeps the function of original telephone communication, but also has the function of words information transmission of a computer and a modem; meanwhile, the utility model has low facility cost and easy use without professional personnel, and is easy to generalize and popularize; the utility model efficiently overcomes insufficiencies of the prior art, and is suitable for digital communications with low-rise velocity request.
Description
The utility model relates to and a kind of monolithic computer and existing communication telephones is combined, has the novel phone of can receiving digital signals and showing with literal or graphics mode, specifically refers to a kind of information telephone with liquid crystal display.
The existing main mode of utilizing telephone wire to carry out the numeral exchange is to connect " modulator-demodulator " or " modem card " by computer, computerized information is exported or input by modulation or demodulation, because this mode need adopt computer and exchanges data application software and modulator-demodulator when using, as adopt personal computer (PC), and exist that use cost is higher, volume is big and the user must grasp the deficiency of the operation sequence of computer, makes it be difficult to popularize.
The purpose of this utility model just is to provide the simple monolithic computer of a kind of employing to combine with existing plain old telephone, and have can receiving digital signals and with literal or the graphics mode information telephone by the band liquid crystal display of liquid crystal display, to overcome the deficiencies in the prior art effectively.
The purpose of this utility model realizes in the following manner: this information telephone mainly is by installing in existing telephone casing or special shell, receive and transmitter by signal, data storage, central processing unit, circuit board that LCD is formed and existing telephone dialing keyboard are formed, wherein signal receives and transmitter employing dtmf code decoder or dtmf decoder, respectively with the phone inlet wire, dialing keyboard and central processing unit link to each other, central processing unit adopts the single-chip computer, and link to each other with liquid crystal display systems with data storage, liquid crystal display systems comprises character generator and character library, explicit driving of liquid crystal and display.
Adopt the information telephone of band liquid crystal display of the present utility model, because single-chip computer and existing plain old telephone are organically integrated, make it both keep the communication function of original phone effectively, but also has the Word message transfer function of computer and modulator-demodulator, simultaneously because its operation keyboard adopts the dialing keyboard, easy to use, need not the professional, and equipment cost is cheap, be easy to popularize, overcome the deficiencies in the prior art effectively, be highly suitable for the not high digital communication of rate request.
