Abstract
The utility model relates to a telephone, in particular to a public telephone that can identify the SIM (UIM) card, which can solve the shortage that the present public telephone can not identify the mobile telephone card and also can not use the mobile telephone card to communicate. The technical solving scheme is that the SIM (UIM) card public telephone comprises a singlechip, a handle, a digital input keyboard, a displayer and a power supply on the periphery, wherein the singlechip is separately connected with the digital input keyboard, the handle and the displayer, characterized in that the singlechip is also connected with a GSM/CDMA communicating module and a card reader; and the power supply can use 220V alternating current external power supply and also can use the direct current spare battery. The output end of the external power supply is connected with the input end of the GSM/CDMA communicating module, the spare battery is connected with the GSM/CDMA communicating module and the power supply input end of the card reader, and the singlechip is externally connected with a storage device. The GSM/CDMA communicating module is a wireless MODEM and linked out by a connector, and a complete duplex serial port of the module is connected with a complete duplex serial port of the singlechip. The utility model is mainly applicable for the public telephone which uses the mobile telephone card to communicate.
Description
Technical field: the utility model relates to a kind of telephone set, particularly a kind of SIM (UIM) card public telephone set of discerning.
Background technology: at present, employed unattended operation type wireless public telephone mainly is wireless GSM public telephone on the market.The prerequisite of using this phone is to have corresponding card, will input tediously long card number and password when calling, and uses inconvenience, and the clearing of telephone expenses are also complicated.
Summary of the invention: the utility model technical issues that need to address are: when using account card and stored value card to call in order to solve the public telephone terminal, the fail safe of charge system and the complexity of handling process, and a kind of off-line type collateral information source is provided for the public telephone user, make it obtain personal information to greatest extent under prerequisite cheaply, as long as a kind of phone that has the mobile phone card to get final product communication is provided.
For realizing above-mentioned purpose, the technical solution of the utility model is: SIM (UIM) blocks public telephone set, comprise single-chip microcomputer, handle, digital input keyboard, display and peripheral power supply, single-chip microcomputer connects digital input keyboard, handle, display respectively, it is characterized in that, single-chip microcomputer also connects GSM/CDMA communication module and card reader, and power supply can also can be used the direct current backup battery with the interchange external power supply of 220V.The output of external power supply with GSM/CDMA communication module input link to each other, backup battery links to each other with the card reader power input with the GSM/CDMA communication module, single-chip microcomputer adopts 8031 series, it is the control centre of entire circuit, external memory.The GSM/CDMA communication module is a wireless modem, connect by connector, the full duplex serial port of this module links to each other with full duplex serial port on the single-chip microcomputer, realize intercommunication mutually, single-chip microcomputer is by sending various AT orders, and may command GSM/CDMA communication module cooperates between subscriber card and the mobile radio communication finishes the function that multiple mobile communication system such as voice transfer, data communication short message receiving-transmitting can provide.Each button of digital input keyboard is scanned by the expansion parallel port of single-chip microcomputer.
The beneficial effects of the utility model are that this phone can be suitable for SIM card, also is applicable to the UIM card of CDMA simultaneously.As long as the user takes out the SIM in the mobile phone (UIM) card, insert the card reader of this phone, promptly can call (comprising local telephone network and toll telephone), have the Chinese message function of transmitting-receiving simultaneously, telephone expenses can be directly by deducting in the employed card.After having made a call, take the card of oneself away.Phone cannot be dialed any phone under the situation of not having card.Solve the problem that to call as under the situation that nothing is blocked and mobile phone can't use, provide a kind of brand-new terminal traffic value-added tool to mobile operator simultaneously.
Description of drawings:
Accompanying drawing is a circuit structure block diagram of the present utility model
Among the figure: 1-single-chip microcomputer, 2-display, 3-digital input keyboard, 4-handle, 5-GSM/CDMA communication module, 6-1-external power supply, 6-2-backup battery, 7-card reader, 8-memory.
Embodiment:
SIM (UIM) blocks public telephone set, comprise single-chip microcomputer 1, handle 4, digital input keyboard 3, display 2, GSM/CDMA communication module 5, card reader 7 and peripheral power supply, single-chip microcomputer 1 connects digital input keyboard 3, handle 4, display 2, GSM/CDMA communication module 5, card reader 7 respectively, power supply can also can be used direct current backup battery 6-2 with the interchange external power supply 6-1 of 220V.The output of external power supply 6-1 with GSM/CDMA communication module 5 inputs link to each other, backup battery 6-2 links to each other with card reader 7 power inputs with GSM/CDMA communication module 5, display 2 adopts LCD LCD, single-chip microcomputer 1 adopts 8031 series, it is the control centre of entire circuit, external memory 8.GSM/CDMA communication module 5 is wireless modems, connects by connector, and the full duplex serial port of this module links to each other with full duplex serial port on the single-chip microcomputer.The utility model adopts components and parts to purchase from the market.
The use of this phone is as follows: off-hook, insert the SIM/UIM card, when plug-in card puts in place, phone powers on, and the login of networking automatically, sign in to the success of corresponding network after, phone enters normal standby interface, and (UNICOM can show " CHINAUNICOM ", move and show " China Mobile "), show the current Virtual network operator that inserts of phone.After several seconds, show " please dial ", the user can call this moment, when dialing, single-chip microcomputer can detect the number of being dialled and show on display screen, if dial the wrong number, the user can cancel the number of being dialled by cancel key, after having dialled number, by sending key, single-chip microcomputer can notify gsm module or CDMA module that this number is sent.This moment, module was when sending out number, and the result is returned to single-chip microcomputer.If connect, module can be returned the message of a connection, and this moment, phone picked up counting, and showed on display screen.Behind the end of conversation, module can send the information of an end, and phone then stops timing, after the on-hook, can send the prompt tone of card taking, reminds the user to take out the SIM/UIM card.
Do not connect as phone, communication module can return messages be notified, and single-chip microcomputer then shows the information of access failure and points out the user to dial later on again, sends the prompt tone of card taking on display screen.
