AI Technical Summary
During vehicle operation, drivers need to frequently switch radio frequencies manually to receive broadcast signals from different cities, resulting in a decreased driving experience.
The vehicle's location is determined by its positioning system, and the vehicle radio actively searches for and saves valid radio stations. This includes receiving radio signals with the receiving antenna, locking frequencies with the tuner, and amplifying signals with the amplifier to achieve automatic radio station search.
It reduces the time and hassle for drivers to manually search for radio stations when switching between different cities, and enables accurate automatic radio station search and playback without the need for network support.

Abstract
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.
