Abstract
The invention relates to a radio play control method. According to the method, a path of high-frequency carrier filtering unit is externally adopted. The method comprises the following steps of: acquiring the frequency of current useful radio station through scanning of the high-frequency carrier filtering unit, and updating a selectable radio station set of a radio; acquiring the position where a radio module is positioned at present in real time through a positioning system; in a state of locking the frequency of the current radio station, judging whether the current located geographic region changes or not according to the current located position and position division; if the current located geographic region changes, displaying the name of a radio station which corresponds to the frequency of the current radio station in the current geographic region after the current located geographic region changes; if the current located geographic region does not change, keeping showing the name of the radio station corresponding the frequency of the current radio station in the current geographic region; and during radio station switching, selecting a radio station of which the frequency is different from that of the current radio station from the selectable radio station set according to a receiving instruction or automatically to serve as a switched radio station for relocking. By the method, the radio is convenient, concise, time-saving and movable, and the name of the radio stations can be intuitively shown.
Description
Technical field
The present invention relates to radio and software electronics, be specifically related to a kind of broadcast receiver control method for playing back, especially a kind of control method for playing back of vehicle-mounted radio.
Background technology
Broadcast receiver is formed by structures such as mechanical devices, electronic device, magnet, with a kind of machine of electric energy with electric wave signal conversion and energy broadcast listening radio station audio signals.Have another name called radio, broadcasting etc.Its operation principle is that the high-frequency signal that receives from antenna is reduced into audio signal through detection (demodulation), delivers to earphone or loudspeaker become sound wave.Because scientific and technological progress, the sky has had the radio wave of a lot of different frequencies in the air.If these many electric waves are all received, audio signal will be as being among the downtown area, and many sound are mixed in together, and the result has not heard whatever.In order to manage to select needed program, behind reception antenna, a selective circuit is arranged, its effect is that required signal (radio station) is picked out, and the signal of not wanting " is filtered ", disturbs in order to avoid produce, during Here it is our broadcast listening, employed " channel selection " button.The output of selective circuit is the high-frequency am signal of selecting certain radio station, it is not all right utilizing it directly to promote earphone (zund-Burguet apparatus), also must revert to original audio signal to it, and this primary circuit of going back is called demodulation, the audio signal of demodulation is delivered to earphone, just can receive broadcasting.At present, vehicle-mounted radio is widely used, because vehicle moves channel selection automatically better, and memory or sweep platform (scanning frequency) at every turn and all be to use and be not suitable for or inconvenience, and if do not have station name can cause driver or passenger's broadcasting station play to use obstacle or puzzlement yet.
Summary of the invention
The technical issues that need to address of the present invention are, how a kind of broadcast receiver control method for playing back is provided, and can adjust optional radio station and show the title in current locking radio station according to signal dynamics.
Above-mentioned technical problem of the present invention solves like this: make up a kind of broadcast receiver control method for playing back, it is characterized in that, comprise two road high frequency carrier filter units in the corresponding broadcast receiver, the first via is used for the locking current broadcast station frequency, the second the tunnel is used for the useful frequency of scanning, this control method for playing back utilizes the position of the geographic area of storage inside to divide and frequency of radio station and the corresponding station name of each geographic area, specifically may further comprise the steps:
Carry out frequency scanning by the second road high frequency carrier filter unit, obtain current useful frequency of radio station and self wireless optional radio station collection is upgraded;
Obtain self wireless current position in real time by navigation system;
Under locking current broadcast station frequency state, divide judge whether geographic area, current place changes according to current position and described position: as if changing, the station name of current broadcast station frequency correspondence in the geographic area, current place behind the display change then; Otherwise then maintenance shows the station name of current broadcast station frequency correspondence in the geographic area, current place;
When handoff radio, choose different with current broadcast station frequency one and relock as the current broadcast station frequency after switching by receiving instruction or concentrating from described optional radio station automatically.
Two road high frequency carrier filter units have avoided traditional broadcast receiver time can only carry out a kind of in radio reception or the scanning; This Display Technique scheme considers that storage inside data and actual conditions are not inconsistent still and can effectively work in addition.Two road high frequency carrier filter units preferably share a cover antenna.
