Description
Technical field
The utility model relates to moving communicating field, and particularly, relates to the multiplexer of portable terminal and intercom.
Background is smeared art
Along with the maturation and the development of mobile communication technology, be that the function of portable terminal of representative is more and more with mobile phone (claiming mobile phone again).The user not only requires mobile phone to have the function of conversation, transmitting-receiving short message, sends and receive e-mail, browsing page, playing back music, views and admires functions such as film, photograph, GPRS but also wish to have.These functions have been brought very big convenience to people, meet fast pace, high efficiency social demand, are subjected to user's welcome deeply.
Simultaneously, intercom (claiming walkie-talkie again) is because advantages such as easy communication, zero telephone expenses have obtained application widely in multiple occasions such as family, enterprise, tourism, rallies.
In order to use portable terminal and intercom simultaneously, the user has to carry simultaneously this two kinds of handheld devices, and this has brought certain inconvenience to the user.
The utility model content
The purpose of this utility model is to separate the inconvenience that brings to the user with intercom for solving portable terminal, proposes a kind of device that has merged intercom function and mobile terminal function.
For achieving the above object, the utility model provides the multiplexer of a kind of portable terminal and intercom, it is characterized in that, comprising: portable terminal master chip and intercom communication module baseband chip, intercom communication module baseband chip is connected with described portable terminal master chip;
Further, described device has also comprised the analog switch that links to each other with the portable terminal master chip, and transmitter links to each other with intercom communication module baseband chip and portable terminal master chip by analog switch with receiver.
Receiver in the described device, transmitter, receiver, transmitter can directly link to each other with the portable terminal master chip, and intercom communication module baseband chip links to each other with receiver with transmitter by the portable terminal master chip.
The above-mentioned user interface that also comprises, user interface links to each other with portable terminal master chip or intercom communication module baseband chip.
The portable terminal master chip of said apparatus and intercom communication module baseband chip transmit digital information by serial port protocol.
The utility model is integrated into the function of intercom in the portable terminal, the user can use this function according to the needs of oneself, when not needing to carry out cellular based communication, the user can use intercom function, and this will save many communication costs to the user and also offer convenience for it.
Description of drawings
Fig. 1 is a fundamental block diagram of the present utility model;
Fig. 2 is the circuit theory diagrams of an embodiment of the present utility model;
Fig. 3 is the circuit theory diagrams of another embodiment of the utility model.
Embodiment
Referring to Fig. 1, device of the present utility model is divided into two partly, portable terminal part and intercom part, the portable terminal part mainly comprises the portable terminal master chip, it combines with user interface, receiver, transmitter and is common portable terminal, the intercom part mainly comprises intercom module base band master chip, and it combines with user interface, receiver, transmitter and is common intercom.In the device of the present utility model, intercom module and mobile terminal module can be carried out handshaking also shared user interface, receiver, transmitter mutually, by described handshaking, can realize the control of portable terminal master chip to the intercom module, the portable terminal master chip also can the main controlling user interface, receiver and transmitter switch between portable terminal and intercom.Certainly, whole device also can carry out master control by the intercom module, and the mobile terminal module conduct is from control.
Referring to Fig. 2, it is the circuit theory diagrams of an embodiment of the utility model, and the utility model device comprises first antenna, second antenna, portable terminal master chip, receiver, transmitter, intercom module baseband chip, power amplifier and analog switch.First antenna is the antenna that portable terminal uses, link to each other with power amplifier, power amplifier links to each other with the portable terminal master chip, and the portable terminal master chip links to each other with the intercom module with analog switch, and analog switch links to each other with intercom module, receiver and transmitter.Communicate by serial ports or other agreements between portable terminal master chip and the intercom module, mutually transfers voice information.
When the user used intercom function in the described portable terminal, the portable terminal master chip sent control signal and gives analog switch, and analog switch switches to the intercommunication pusher side with transmitter passage, receiver passage; Simultaneously, the portable terminal master chip give the intercom module give an order (can but be not limited to by serial communication or I
2The C bus), make it enter the intercom communication state; When ascending voice information that the transmitter sensitivity arrives, by analog switch ascending voice information is delivered to the intercom module and carry out encoding and decoding, and then go out by second antenna transmission; Corresponding, the intercom module with the second antenna sensitivity to downlink voice information carry out encoding and decoding after, deliver to receiver by analog switch and send voice messaging.At this moment, described portable terminal can be realized the function of intercom fully.
After the user finished communication, the portable terminal master chip sent control signal and gives analog switch, and analog switch switches to mobile terminal side with transmitter passage, receiver passage; Simultaneously, the portable terminal master chip sends sleep command for the intercom module by serial communication, makes it enter sleep mode, reaches the purpose of saving electric weight.
Another circuit theory diagrams of this portable terminal are referring to Fig. 3, voice messaging and data message all send receiver and transmitter to by portable terminal master chip device, and are switched between portable terminal and intercom module by portable terminal master chip control receiver, transmitter.
Need illustrate to such an extent that be, Fig. 2 and Fig. 3 have only provided the circuit diagram of portable terminal master chip as master control side, and the utility model also can make the intercom module carry out master control.
In such scheme, described intercom module, can be installed in the portable terminal casing or casing on; Also can make annex, link to each other with mobile phone by cable.The intercom module can use serial port communicating protocol, I
2C bus protocol or other agreements and microprocessor communicate.
