Abstract
A vehicle-mounted radio capable of adjusting frequency automatically relates to a vehicle-mounted radio, in particular to frequency adjustment function of the vehicle-mounted radio. The vehicle-mounted radio comprises a radio shell arranged on a navigation bridge shell, a loudspeaker arranged on the radio shell, a radio main control circuit arranged inside the radio shell and an antenna arranged on the radio shell. The vehicle-mounted radio further comprises a signal searching module, a signal strength comparing module and a frequency adjustment module and has the advantages that the signal searching module is in a signal searching state for a long time and sends searched signals to the signal strength comparing module which compares the searched signals and sends channel signals of optimum signals to the frequency adjustment module, the frequency adjustment module defines the channel of the strongest signals as the present broadcasting channel and sends the broadcasting information to the radio main control circuit which broadcasts program on the channel through the loudspeaker.
Description
Technical field
The utility model relates to vehicle-mounted radio, relates in particular to the frequency modulation function of vehicle-mounted radio.
Background technology
Present vehicle-mounted radio, all be to start automatic function of search through the driver earlier when transferring platform, determine that according to signal strength signal intensity the channel of a best results listens to then, but, automobile is to run in different areas, peak signal is constantly to change, so the transposing channel that the driver need not stop just can reach best audibility; But along with the continuous development of vehicle mounted multimedia, people need a kind of vehicle-mounted radio that can automatic frequency adjustment makes it to be in for a long time a kind of best audibility, like this, make function automation more, the hommization of vehicle mounted multimedia.
The utility model content
The utility model is at the deficiencies in the prior art, but aims to provide a kind of vehicle-mounted radio of automatic frequency adjustment, makes listening on the channel that channel is in peak signal for a long time of vehicle-mounted radio by signal strength signal intensity comparison module and frequency modulation module.
The utility model is achieved through the following technical solutions: but a kind of vehicle-mounted radio of automatic frequency adjustment, comprise the broadcast receiver housing, the loudspeaker that is arranged at the broadcast receiver housing that are arranged at the bridge housing, the broadcast receiver governor circuit of broadcast receiver enclosure interior is set and is arranged at the antenna of broadcast receiver housing, the utility model also comprises signal search module, signal strength signal intensity relatively module and frequency modulation module; Described antenna is provided with the aerial signal output interface, described signal search module is provided with search signal input interface and search signal output interface, described signal strength signal intensity comparison module is provided with signal strength signal intensity comparison module by signal input interface and signal strength signal intensity compares the module by signal output interface, and described frequency modulation module is provided with frequency modulation module by signal input interface and frequency modulation module by signal output interface; Wherein, described aerial signal output interface is connected with described search signal input interface signal, described search signal output interface compares module by signal input interface signal with described signal strength signal intensity and is connected, described signal strength signal intensity relatively module by signal output interface is connected with described frequency modulation module by signal input interface signal, and described frequency modulation module by signal output interface is connected with described broadcast receiver governor circuit signal.
The beneficial effects of the utility model are: one, signal search module of the present utility model are in a kind of signal search state for a long time, and the signal that searches is passed to relatively module of signal strength signal intensity, signal strength signal intensity comparison module compares the signal strength signal intensity of search, and the channel signals of optimum signal passed to the frequency modulation module, the frequency modulation module is defined as the channel of this peak signal current broadcasting channel and broadcast information is passed to the broadcast receiver governor circuit again, and the broadcast receiver governor circuit will be play the program of this channel by loudspeaker; Two, the utility model is simple in structure, and is convenient and practical, and saved the trouble that driver oneself changes platform.
