Vehicle-mounted terminal radio station searching method

Abstract

The invention discloses a vehicle-mounted terminal radio station searching method, and relates to the field of frequency modulation broadcasting technology and software technology, and the method comprises the following steps: S1, determining the coordinates of a vehicle through a vehicle positioning function, so as to determine the current city of the vehicle; s2, actively searching available effective radio stations in a wave band through a vehicle-mounted radio, and keeping the available effective radio stations in a vehicle-mounted system; s3, when the vehicle is in the current city, the vehicle-mounted radio directly searches and listens to the stored radio station; according to the method, the geographic position is determined based on vehicle positioning, the effective radio stations can be actively searched and stored in cooperation with the vehicle-mounted radio, the time and trouble of manually searching the radio stations when the driver switches among different cities are reduced, the whole process can be completed without a network, and the efficiency is improved. And positioning is accurate and practical.

Description

Technical Field

[0001] The patent of this invention relates to the field of FM broadcasting technology and software technology, specifically a method for searching radio stations for vehicle-mounted terminals. Background Art

[0002] As a basic configuration of a vehicle, the radio plays an indispensable role. During driving, it can not only soothe the driver's emotions and reduce driving pressure, but also provide real-time traffic information. The radio is undoubtedly the most frequently used function in the car. However, during driving, drivers often need to travel through different cities, and the radio frequency bands in each city are different. Due to the geographical limitations of the frequency bands, drivers can only search for radio stations of the corresponding frequency bands within the coverage area of ​​the radio station, which often results in the driver being unable to receive effective broadcast signals, thereby greatly reducing the driving experience.

[0003] Invention patent content

[0004] The purpose of this invention is to provide a vehicle-mounted terminal radio station search method to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a method for searching radio stations of a vehicle terminal, comprising the following steps:

[0006] S1: Confirm the vehicle coordinates through the vehicle positioning function to determine the city where the vehicle is currently located;

[0007] S2: Actively search for available radio stations in the band through the car radio and save them to the car system;

[0008] The method of the vehicle radio actively searching for available effective radio stations within the band is as follows: the radio signal is captured by the receiving antenna, then the tuner accurately selects and locks the desired broadcast frequency, and then the amplifier circuit amplifies the signal strength;

[0009] The effective radio station refers to a radio station that can stably transmit or receive signals and provide high-quality communication or broadcasting services;

[0010] S3: When the vehicle is in the current city, the car radio directly searches for the saved radio stations;

[0011] S4: The driver selects a saved radio station to play according to demand.

[0012] The beneficial effects achieved by the patent of the present invention are: determining the geographic location based on the vehicle positioning, and actively searching and saving valid radio stations in conjunction with the car radio, reducing the time and trouble of the driver manually searching for radio stations when switching between different cities. The entire process can be completed without the need for a network, and the positioning is accurate and practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 The figure is a flowchart of a method for searching radio stations for a vehicle terminal in an embodiment. DETAILED DESCRIPTION

[0014] The present invention is further described below in conjunction with the accompanying drawings.

[0015] like Figure 1 As shown, the present invention discloses a vehicle-mounted terminal radio station search method, comprising the following steps:

[0016] S1: Confirm the vehicle coordinates through the vehicle positioning function to determine the city where the vehicle is currently located;

[0017] S2: Actively search for available radio stations in the band through the car radio and save them to the car system;

[0018] The method of the vehicle radio actively searching for available effective radio stations within the band is as follows: the radio signal is captured by the receiving antenna, then the tuner accurately selects and locks the desired broadcast frequency, and then the amplifier circuit amplifies the signal strength;

[0019] The effective radio station refers to a radio station that can stably transmit or receive signals and provide high-quality communication or broadcasting services;

[0020] S3: When the vehicle is in the current city, the car radio directly searches for the saved radio stations;

[0021] S4: The driver selects a saved radio station to play according to demand.

[0022] The present invention determines the geographic location based on vehicle positioning, and can actively search and save valid radio stations in conjunction with the car radio, thereby reducing the time and trouble of the driver manually searching for radio stations when switching between different cities. The entire process can be completed without the need for a network, and the positioning is accurate and practical.

[0023] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and invention concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
