The utility model is composed of a Bluetooth chip, a keyboard function module, a UART, a speech function module, a power supply, a crystal vibrator and an antenna, wherein the Keyboard function module is connected to the Bluetooth chip, the UART receives and transfers AT commands, controls the Bluetooth chip to realize data initialization, complex data conversion and other functions, and offers display signals, the speech function module which offers an MIC interface and an SPK interface is connected to a microphone and a loudspeaker of a vehicle conversation device, the power supply supplies power to the Bluetooth chip, the crystal vibrator generates a clock for the Bluetooth chip and the antenna is connected to the Bluetooth chip. The utility model as an internally embedded type module of a vehicle hand-free conversation device can be embedded into the vehicle conversation device so as to realize the wireless hand-free function, thereby, the goal of answering a telephone and making a telephone all by a cell phone safely in the hand-free mode in the driving state is achieved.
Description
Technical field
The utility model relates to Bluetooth wireless technology, is specifically related to answer and call when a kind of convenience is driven, and the embedded blue tooth vehicular hand-free call module of support voice dial feature.The application technology that belongs to short-distance wireless communication technology.
Background technology
Bluetooth (Bluetooth) technology is the short distance radio communication standards of being developed jointly by mobile operator and mobile computing company, and design is used in sets up a kind of small-sized, economic, short-range Radio Link between portable computer, mobile phone and other mobile devices.The frequency range of regulation and stipulation work is public ISM band, and peak data rate can reach 1Mbps.
Existing Bluetooth technology is applied in vehicle mounted call device aspect and reaches its maturity, as Motorola's " car handsfree communication system ", the HGB of Sony-Ericson Bluetooth vehicle mounted hand-free device etc.Rely on the Bluetooth technology standard, realized the wireless telecommunications of vehicle mounted call device.But this technology is used and only being found expression in incoming call and answer the aspect, and dialing still will could realize by bluetooth cellular phone, also support voice dial feature not, and limitation is very lofty.
The content of utility model
Deficiency at above-mentioned prior art existence, answer and call when the purpose of this utility model is to provide a kind of convenience to drive, and the embedded module with voice dial-up function is for car handsfree communicator real " wireless " provides total solution.
For achieving the above object, the utility model adopts following technical scheme:
The blue tooth vehicular module is made up of Bluetooth chip, Keyboard functional module, UART, speech function module, power supply, crystal oscillator and antenna; The Keyboard functional module is connected with Bluetooth chip, and external connection keyboard IO is provided mouth; The user can answer, refuse to listen and hang up the telephone and regulate volume by the vehicle mounted call device external connection keyboard that links to each other with the IO mouth; UART receives and transmits the AT instruction, and the control Bluetooth chip is realized functions such as data initialization and complex data conversion, and shows signal is provided, and supports the incoming call/missed call and the dialing Presentation Function of vehicle mounted call device; Speech function module provides MIC and SPK interface, connects the microphone and the loud speaker of vehicle mounted call device; Power supply and crystal oscillator are respectively the Bluetooth chip power supply and produce clock; The AT instruction is mutual by UART and Bluetooth chip, controls each functional block and exercises function separately; Antenna is connected with Bluetooth chip.
The utility model can embed the vehicle mounted call device easily as the embedded module of a kind of car handsfree communicator, for it realizes the wireless hands-free function.Mutual by Bluetooth chip and Keyboard functional module, speech function module can reach by Bluetooth wireless technology and make the vehicle mounted call device realize dialing and transferring voice, beat the purpose of answering the call with hands-free way safe handling mobile phone under driving condition.
Description of drawings
Accompanying drawing has provided the structural representation of an indefiniteness embodiment of the utility model.
Among the figure: 10-antenna, 11-Bluetooth chip, 12-Keyboard functional module, 13-UART, 14-speech function module, 15-SPK interface, 16-MIC interface, 17-crystal oscillator, 18-power supply.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.In explaining process of the present utility model, omit the detailed description of known function and structure.
As shown in Figure 1: this accompanying drawing is the hardware configuration schematic diagram of embodiment, antenna 10 links to each other by the radio frequency interface of radio frequency line with Bluetooth chip 11, its mobile phone signal passes to Bluetooth chip 11 and handles, and the signal after Bluetooth chip 11 handled passes to bluetooth cellular phone by antenna 10, and this antenna can be selected AT 9520 products of Advanced Ceramic X company for use.Bluetooth chip 11 is nucleus modules of this utility model, handles and change various function signals and instruction, can adopt the BlueCore02-Flash module of CSR company to realize.Keyboard functional module 12 provides external IO mouth, pick up vehicle mounted call device external connection keyboard answer, refuse listen and hang up the telephone and regulate various signals such as volume; By Bluetooth chip 11, the signal these conversion of signals become mobile phone to use passes to bluetooth cellular phone by antenna, thereby realizes answering, refuse to listen and hang up the telephone and volume adjusting function.UART13 receives and transmits various AT and instruct to Bluetooth chip 11, makes Bluetooth chip 11 realize data initialization and complicated functions such as data transaction.Bluetooth chip provides incoming call, name and the telephone number shows signal of vehicle mounted call device.Phonetic function piece 14 has two kinds of implementations, can be embedded in the Bluetooth chip 11; Also can place as shown in the figure outside the Bluetooth chip 11, SPK interface 15 and MIC interface 16 are provided, SPK interface 15 connects vehicle mounted call device external loudspeaker, the 10CY32 product that the SPK interface can adopt Kai Qi company to produce; MIC interface 16 connects the external microphone of vehicle mounted call device.Speech function module 14 is used for transmitting and picking up audio signal, by the processing and the conversion of Bluetooth chip 11, thereby realizes functions such as this utility model phonetic dialing, voice reporting number.The MC145483 module that speech function module 14 can adopt Motorola to produce.Crystal oscillator 17 and power supply 18 are respectively Bluetooth chip 11 and produce clock and power supply, and wherein crystal oscillator can adopt the DAW-191-451-J product that NDK company produces.
The utility model proposes the solution of the characteristics that have more at the deficiency of traditional product.Realize at on-vehicle hands-free device on the basis of wireless communication, support directly dialing and phonetic dialing on on-vehicle hands-free device.
