Embodiment Construction

[0012] Such as figure 1 As shown, it is a framework diagram of an application environment of a preferred embodiment of the FM broadcast intelligent conversion system of the present invention. The FM radio intelligent conversion system 11 is installed and operated in the FM radio receiver 1 . The FM radio receiver 1 also includes a FM receiver 12 for receiving broadcast signals from various broadcast stations. In this preferred embodiment, the FM broadcast receiver 1 is a vehicle-mounted broadcast receiving system; in other embodiments, the FM broadcast receiver 1 may be other types of broadcast receiving systems.

[0013] The FM broadcast radio 1 is also connected with a GPS system 2 for obtaining the current location of the FM broadcast radio 1 . The GPS system 2 includes a GPS signal receiver 21 and an electronic map 22 . The GPS system 2 obtains the current location of the FM broadcast radio 1 by receiving the GPS satellite signal through the GPS signal receiver 21 there...

Abstract

The invention provides a frequency modulation broadcast intelligent switching method, which comprises the following steps: establishing a broadcast frequency database; receiving a current broadcast station of a frequency modulation broadcast receiver through a frequency modulation receiver and acquiring corresponding current broadcast station frequency; acquiring a current position of the frequency modulation broadcast receiver through a global positioning system and determining an area which the frequency modulation broadcast receiver belongs to; reading region broadcast station frequency corresponding to the current broadcast station in the belonged area from the broadcast frequency database; judging whether the read region broadcast station frequency is the same as the received current broadcast station frequency; and when the read region broadcast station frequency is not the same as the received current broadcast station frequency, switching the current broadcast station frequency of the frequency modulation broadcast receiver into the region broadcast station frequency. The method can automatically switch the receiving frequency of the broadcast station acquired by the frequency modulation broadcast receiver and ensure that the frequency modulation broadcast receiver receives stable broadcast station signals.

Description

technical field [0001] The invention relates to an FM broadcast intelligent conversion system and method. Background technique [0002] FM radio (frequency modulation radio) is one of the sources of information commonly used by people. FM broadcast radios have an FM receiver for receiving broadcast signals transmitted by various broadcast stations. A phenomenon inherent in FM receivers is called capture, that is, the FM receiver can clearly receive the stronger of two broadcast stations on the same frequency. Therefore, in general, if you use an FM broadcast radio to listen to the broadcast at a fixed location, there will be very little signal interference. [0003] However, due to the same radio station in different regions, its transmission power is not the same. As a result, when the place of use of the user who uses the FM broadcast radio changes, the frequency at which the FM broadcast radio receives a certain station may be different. This is especially likely to h...
