It further, further include GPS module, the GPS module is connect with processor communication.

It further, further include fm dial, the fm dial is electrically connected with processor.

By using preceding solution, the beneficial effects of the utility model are: this vehicle-mounted talkback unit passes through function in advance By key assignments and customized communication channel can be saved, vehicle-mounted talkback unit can recognize that the vocal print of user determines user identity, when After confirming user's vocal print, user can automatically switch to some customized communication frequency by the vehicle-mounted talkback unit of voice command Road, then vehicle-mounted talkback unit can be communicated with the intercom or vehicle-mounted talkback unit for using the customized communication channel.This Vehicle-mounted talkback unit is additionally provided with GPS module, can be in real time to being equipped with the bus location of this vehicle-mounted talkback unit, and is shown in vehicle On the display screen for carrying talkback unit, user is facilitated to obtain location information.User can also be by fm dial come frequency modulation, frequency modulation rotation The priority level of button is lower than customized communication channel set by user, when user's not intercommunication with the customized communication channel of use It, just can be by fm dial come frequency modulation when machine or vehicle-mounted talkback unit are communicated.

Detailed description of the invention

Fig. 1 is the circuit connection block diagram of the utility model embodiment.

Specific embodiment

Now in conjunction with the drawings and specific embodiments, the present invention will be further described.

With reference to Fig. 1, the present embodiment provides a kind of vehicle-mounted talkback units, including processor 1, lithium battery 2, display screen 3, function Key 4, loudspeaker 5, microphone 6, fm dial 7, GPS module 8, speech recognition module 9, voiceprint identification module 10, frequency inspection Survey unit 11, Receiver Module 12, digital frequency-selecting module 13, radiofrequency emitting module 14.The processor 1 uses STM21L4 Processor, the frequency detecting unit 11 use a kind of Chinese patent application publication No. CN103713280A (Frequency detection Formula radio altimeter simulator) disclosed in frequency detecting unit.Above-mentioned each circuit module is existing well-known technique.Institute State the voice command of the user for identification of speech recognition module 9, the vocal print of the voiceprint identification module 10 user for identification comes Determine user identity.

The lithium battery 2 is electrically connected with 1 power end of processor, is powered for processor 1.The display screen 3, function button 4, Loudspeaker 5, microphone 6, fm dial 7 are electrically connected with processor 1 respectively, and the function button 4 sets customized for user Communication channel (customized communication channel includes setting frequency point and infrasonic), customized communication channel is stored in processor 1.Institute GPS module 8 and processor 1 is stated to communicate to connect, GPS module 8 can in real time to the bus location for being equipped with this vehicle-mounted talkback unit, and It is shown on the display screen 3 of this vehicle-mounted talkback unit, user is facilitated to obtain location information.The microphone 6 and speech recognition mould Block 9 is electrically connected, and the speech recognition module 9 is electrically connected with processor 1.The microphone 6 is electrically connected with voiceprint identification module 10, The voiceprint identification module 10 is electrically connected with processor 1, and the Receiver Module 12 is electrically connected with processor 1, the frequency Detection unit 11 is electrically connected with Receiver Module 12, and the frequency detecting unit 11 is electrically connected with processor 1, the number choosing Frequency module 13 is connect with processor electricity 1, and the digital frequency-selecting module 13 is electrically connected with radiofrequency emitting module 14.

The working principle of this vehicle-mounted talkback unit: user using this vehicle-mounted talkback unit before use, function can be passed through in advance Energy key 4 sets and saves customized communication channel, such as is set with channel one, channel two and channel three.When vehicle-mounted intercommunication fills It sets after identifying that the vocal print of user determines user identity, user can automatically switch to some by the vehicle-mounted talkback unit of voice command Customized communication channel, such as user issue order " connection channel two ", at this time vehicle-mounted talkback unit can with use channel two Intercom is communicated；When user is essential channel three to be switched to, order " connection channel three " is issued；When user not with make by oneself When interphone communication in adopted communication channel, user issues order " disconnecting ", passes through identification user's vocal print and voice command Vehicle-mounted talkback unit is operated, from manual operation.User can also be by fm dial 7 come frequency modulation, the priority scheduling of fm dial 7 Grade can just lead to lower than customized communication channel set by user when user does not communicate with customized communication channel It crosses fm dial 7 and carrys out frequency modulation.When user receives the electromagnetic wave information that other talkback units are sent, frequency detecting unit 11 is detected The electromagnetic wave frequency range passes to processor 1, and processor 1 judges whether electromagnetic wave frequency range is customized communication channel.For example, when place Reason device 1 judges electromagnetic wave frequency range for the frequency range of channel one, then processor 1 controls display screen 3 and shows " channel one ", while loudspeaker 5 broadcast voice informations.

The voice command of above-mentioned vehicle-mounted talkback unit can be according to the habit self-setting of user.

Although specifically showing and describing the utility model in conjunction with preferred embodiment, those skilled in the art is answered This is understood, in the spirit and scope for not departing from the utility model defined by the appended claims, in form and details On the utility model can be made a variety of changes, be the protection scope of the utility model.
