When bluetooth cellular phone is received the signal of calling, at first signal receives by antenna and amplifies, this moment, mobile phone sent a series of instruction to bluetooth handsfree, after bluetooth host receives these instructions, digital signal is converted to analog signal, and decoder is deciphered, through frequency switch circuit, provide signal and drive frequency switch circuit work, sound equipment is switched to mute state, again audio signal is play by the right front loudspeaker of automobile, input is then by microphone, thereby the realization hand-free function also can utilize External micro phone to converse, can also caller ID be shown by adding display driver and display circuit.
When if the user uses this car phone gsm system to communicate, when Outgoing Call, can import by dialing keyboard, signal sends through microprocessor and GSM radio-frequency module, and the action of hands-free part also is to be realized by microprocessor control audio commutation circuit.Working method when incoming call is answered is identical with Outgoing Call.The mode that receives calls of this car phone can also earphone and hands-free between, between the hands-free and mobile phone, carry out freely switching between the hands-free and microphone, further other additional function of exploitation is more convenient to use as required.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is a theory diagram of the present utility model;
Fig. 2 is the circuit diagram of bluetooth host in preferred embodiment of the utility model;
Fig. 3,4,5 is the circuit diagram of car phone (GSM) main frame that cooperates with Fig. 2 of the utility model.
Embodiment
If the user is the bluetooth cellular phone user, the utility model embodiment can realize the hand-free function of conversing.Now realize that with regard to bluetooth users the car handsfree principle of work and power is described further.
As shown in Figure 1, the car phone with Bluetooth function of the present utility model mainly comprises three parts:
First is a bluetooth host, is made up of Bluetooth RF transceiver module (containing A/D conversion circuit), coding/decoding circuit, microprocessor, Bluetooth antenna etc., and its building block does not draw among the figure;
Second portion is car phone (GSM) main frame, is made up of emblem processor, frequency switch circuit, power control circuit, remote-control receiving circuit etc.;
Third part is the peripheral hardware of car phone, by receiver, remote controller, automobile audio, automotive acoustic speaker, microphone, and composition such as microphone, earphone.
Power control circuit among the figure provides reliable work energy for whole car phone with Bluetooth function.
The Bluetooth RF transmission circuit is whole hands-free part and parcel, the data that it is responsible for sending out on the bluetooth cellular phone are carried out D/A switch, again by the decoding/encoding circuit, signal after treatment is transferred to respectively by on car phone main frame and the bluetooth cellular phone, sends to current talking side by bluetooth cellular phone again.When its signal is transferred on the car phone main frame, handle, finish the quiet action of sound equipment by the processor in the car phone main frame.
When making a phone call, speaker's sound is converted to analog signal by microphone or microphone with voice signal, wherein microphone is for having mini microphone and Microspeaker function, pass through coding/decoding circuit, Bluetooth RF transceiver module, and give bluetooth cellular phone by antenna transmission with data packet form.When receiving calls, bluetooth cellular phone sends signal, receives through antenna and passes to the Bluetooth RF transceiver module, realizes speech communication by the circuit of back again.The circuit operation of audio frequency switching part is identical when wherein getting phone and receiving calls, as long as the signal input is promptly arranged, the frequency switch circuit in the car phone main frame will move.
Be illustrated in figure 2 as the circuit diagram of bluetooth host in preferred embodiment of the utility model, when the Vehicular phone device with Bluetooth function receives signal, carry out signal processing (D/A switch) by Bluetooth RF transceiver module MSM7731, and signal is transferred to MCI145483 carries out decoding/encoding and handle, between radio-frequency (RF) receiving and transmission module MSM7731 and the bluetooth module bluetooth, by the I/O interface circuit in succession, carry out exchanges data between bluetooth module and the decoding/encoding device MCI145483.
When signal inputed or outputed, microprocessor PIC16C63 the 3rd pin among Fig. 3 will be exported control signal, and when being output as low level, the circuit of being made up of two triode Q203, Q402 with switching function ends, and relay SS16 is failure to actuate; When being output as high level, two triode conductings, relay SS16 action, automobile audio is muted; When end of conversation, the signal that microprocessor PIC16C63 provides during according to end of conversation is from low level of its 3rd pin output, the switching function circuit ends, relay SS16 recovers the state before the action, and the automobile audio mute state is removed, thus the implement device hand-free function.
When using earphone receiving, by signal of earphone input, detect through handling, by microprocessor PIC16C63 the 3rd pin output high level, make drive circuit quiet to sound equipment, and, audio signal by earphone or microphone output, is realized the switching between hands-free and the earphone by microprocessor PIC16C63 control.Wherein earphone is that configuration device can be selected in the outside, is connected by interface with main frame.Microphone and hands-free between conversion be to give control signal of microprocessor PIC16C63 when utilize using microphone, and by microprocessor PIC16C63, audio signal switches to microphone output.More than two kinds of switchings be to utilize the mode of software to control.When the user has left the effective propagation distance of bluetooth, bluetooth host radio-frequency (RF) receiving and transmission module MSM7731 can not receive relevant data, go out instruction through microprocessor the 2nd human hair combing waste, be returned to the state before car phone uses, hand-free function automatically switches on the mobile phone.
If the user is not to use mobile phone (comprising the mobile phone with Bluetooth function), also can use the utility model embodiment to carry out relevant information interchange.Shown in Fig. 3,4,5, its operation principle is: after sending instruction by dialing keyboard or remote controller, a part is carried out signal processing by microprocessor PIC16C63, exporting signal drives the frequency switch circuit action output of sound equipment is stopped, audio signal by Music centre loudspeaker as hands-free output, also can be by microphone or earphone as output; Another part is handled by microprocessor PIC16C63 and is carried out being launched by the GSM radio-frequency module after the noise isolation through photoelectricity coupling device, realizes transfer of data, thus real communication function, and all quiet part operation principles are identical.
This car phone can be formed a wireless anti-theft network with car alarm simultaneously, after its working method is opened for being triggered when alarm, connect the triggering signal of INT pin that to give car phone microprocessor PIC16C63 by interface circuit, send antitheft note by the mobile phone that can set to the user automatically after the microprocessor PIC16C63 processing, remind to love car by illegal invasion, finish realizing of this process by software.
