Abstract
The invention provides an automatic frequency modulation vehicular radio. The invention relates to a vehicular radio, in particular to the frequency modulation function of the vehicular radio. The vehicular radio comprises a radio shell arranged on a driving platform shell, a loudspeaker arranged on the radio shell, a main control circuit in the radio shell, and an antenna of the radio shell. The vehicular radio also comprises a signal searching module, a signal intensity comparing module and a frequency modulation module. The vehicular radio has the benefits that the signal searching module is arranged in a signal searching state for long; furthermore, the searched signal is transmitted to the signal intensity comparing module; the signal intensity comparing module compares the searched signal intensity and transmits the best channel signal to the frequency modulation module; the frequency modulation module determines the channel of the strongest signal as the currently played channel and transmits the playing information to the main control circuit of the radio; and the main control circuit of the radio plays the programs in the channel by the loudspeaker.
Description
Technical field
The present invention relates to vehicle-mounted radio, relate 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.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, but aim to provide the vehicle-mounted radio of automatic frequency adjustment, make 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 present invention is achieved by the following technical solutions: but the 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 present invention 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.
Below above technical scheme is further elaborated:
The present invention also comprises the channel selection module and is arranged on the channel selection button of housing that described channel selection module is connected with described frequency modulation module by signal.
Beneficial effect of the present invention is: one, signal search module of the present invention 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 present invention can also select the program that driver oneself likes in the stronger channel of several signal strength signal intensities by channel selection module and channel selection button, makes the driver can select the favorite program of the stronger program of signal oneself at any time; Three, the present invention is simple in structure, and is convenient and practical, and saved the trouble that driver oneself changes platform.
