Though this on-vehicle positioning terminal that possesses the car phone function provides many-sided service to the user, make troubles in some cases vehicle drive personnel and orientation management, even might cause danger.For example:

1, present, the voice call function of quite a few on-vehicle positioning terminal product is to realize by handle, yet the driver is divert one's attention, cause accident to take place using handle to take on the telephone on the run;

2, some on-vehicle positioning terminal utilizes former car loudspeaker to realize voice call function, can avoid first kind of situation to take place, but, in actual applications, the driver drives to need to be provided with and the incoming call of mobile phone could be transferred to on-vehicle positioning terminal at every turn, cancel after driving again and come electrotransfer, trouble is easily forgotten;

3, owing to rate, most on-vehicle positioning terminals all by GPRS network transmission locator data, still, must withdraw from GPRS network in the voice call process, and can't transmit locator data this moment by GPRS network.

Summary of the invention

The purpose of this utility model is to provide a kind of on-vehicle positioning terminal with blue tooth voice function, can with user's mobile communication with Bluetooth function.

The technical solution of the utility model is: a kind of on-vehicle positioning terminal with blue tooth voice function, comprise end host, described end host comprises central processing module and coupled gsm module, GSM/GPRS module, input/output module and memory module; Also comprise the bluetooth module that links to each other with described central processing module in the described end host, described bluetooth module links to each other with hands-free microphone with the car loudspeaker by audio frequency processing circuit.

Further, described on-vehicle positioning terminal also comprises the gps antenna that links to each other with described GPS module, the GSM antenna that links to each other with the GSM/GPRS module.

The utility model is by introducing bluetooth module, connecting terminal main frame and bluetooth cellular phone, utilize former car loudspeaker and hands-free microphone to realize the hand-free call function, having solved needs incoming call to shift before the existing on-vehicle positioning terminal voice call problem that can not locate in real time during conversation is set.

Embodiment

The present invention is further elaborated with specific embodiment with reference to the accompanying drawings below.

As shown in Figure 3, Figure 4, a kind of on-vehicle positioning terminal with Bluetooth function of the utility model comprises end host 100 and the gps antenna 201 that is connected with end host 100, GSM antenna 202, power supply 203 and hands-free microphone 205.End host 100 comprises central processing module 101, GPS module 102, GSM/GPRS module 103, input/output module 106, memory module 105 and bluetooth module 107.GPS module 102 links to each other with gps antenna 201, GSM/GPRS module and GSM antenna 202 and SIM (Subscriber Identity Module, user identity identification) card 104 links to each other, and bluetooth module 107 links to each other with hands-free microphone 205 with car loudspeaker 204 by audio frequency processing circuit 108.Power supply 203 comprises by vehicular power-bottle and the stand-by power supply of fuse for each module for power supply.

Wherein, end host 100 is used for the operational system program, handles gps data, and mutual with the GSM/GPRS network finished in the I/O Detection ﹠ Controling, realizes input and controls by input/output module 106.

Gps antenna is used to receive the locating information from gps satellite, is forwarded to end host 100.

The GSM/GPRS antenna is used to insert the GSM/GPRS network, realizes the transmission of voice signal and data.

Central processing module 101 is used to move embedded OS and application program, carries out data computation and processing, carries out signal controlling and detection with changing I/O circuit (input/output module 106).

Bluetooth module 107 is used to connect user's bluetooth equipment (mobile phone 206 that for example has Bluetooth function), carries out the transmission of voice signal.Signal from hands-free microphone 205 sends on user's the bluetooth cellular phone 206 by bluetooth module 107 after audio processing modules is handled, signal from bluetooth cellular phone 206 receives by bluetooth module 107, delivers on the car loudspeaker 204 after audio frequency processing circuit 108 is handled and plays.

The GSM/GPRS module is the core component that a kind of on-vehicle positioning terminal with Bluetooth function of the utility model is finished radio communication function.The utility model terminal is by GSM/GPRS module access to wireless communication network, and then communicates and transfer of data with Surveillance center, can finish car phone, short message, information uploading, reports to the police and seek help and receive a series of functions such as Surveillance center's instruction.It should be noted that and to call under the GPRS state when communicating, withdraw from the GPRS state earlier, create telephony task again, enter telephone state with Surveillance center.
