Problems solved by technology

[0002] Car radios have the function of locking favorite programs. Usually, the user selects several channels according to his own preferences and locks them in advance through the lock button. During use, as long as a different lock button is pressed, the radio can receive the program of the station, so , the application of the existing car radio is passive. When the car owner crosses the region, the current radio will have no stations, and it needs to manually re-search and manually re-search and lock the station, and the locked station is not necessarily the one the car owner likes to listen to. channel, which brings inconvenience to the owner

Embodiment 1

[0021] An embodiment of a method for cross-regional automatic channel changing of a car radio, see figure 1 and figure 2 , the method includes a cross-regional auto-switching car radio consisting of a microprocessor module 1, a positioning module 2 (GPS / AGPS satellite positioning or base station positioning unit module) and a radio module 3 (FM / AM tuning and AM radio module) System, the microprocessor module establishes a radio station database in its database memory 1-1, the radio station database includes different regional positioning information, different regional radio program types, radio frequency, set signal strength value level and preset threshold value ( data in memory using binary file format), figure 1 The communication module 4 realizes the user's manual locking of the radio's favorite programs. The method steps are: firstly, according to the user's habit, the favorite programs are locked, and a favorite program file is established; the method steps further in...

Embodiment 2

[0033] Referring to Embodiment 1, in this embodiment, the locking of favorite programs according to user habits and the establishment of favorite program files are: determining favorite program files according to the order of favorite programs locked on the radio by the user in a region.

Embodiment 3

[0035] Referring to Embodiment 1, in this embodiment, locking favorite programs according to user habits and establishing favorite program files can also be: starting from the first time the user searches for stations The frequency of different radio stations is represented by F, and then the frequency list of the current storage station is obtained, the listening time of each station is recorded each time, and the total listening time of each station within the set time is counted, and the total listening time of each station is calculated. The time is marked as T, and F and T are brought into the formula γ=(30+F) 2 +T, arrange multiple γ values ​​in order of size to create a favorite program file.

[0036] The following is a further detailed description of the above-mentioned embodiment:

[0037] First, the frequency information and station names of radio stations in various administrative regions of the country are stored in a car radio system in a database, and GPS satell...

Abstract

The invention discloses a transregional automatic radio station switching method for a vehicle-mounted radio, wherein a vehicle-mounted radio system consisting of a microprocessor module, a positioning module and a radio module is adopted. The transregional automatic radio station switching method comprises the steps of: locking preferential programs and establishing a preferential program file according to the habits of a user; acquiring notices of a new region in which a radio is located, in real time by the positioning module; when the signal intensity of a current radio station is smaller than a preset threshold value, starting and searching radio stations again; recording all the radio stations with signal intensity values more than the threshold value in a frequency band into a list by the radio module, wherein the list comprises the signal intensity values, frequencies and radio station types determined according to information in a radio station database; and comparing the preference program file with the list one by one, and locking the frequency of the radio stations with the same types as that of preferential programs in the list, in the radio. According to the invention, the functions of automatic radio station searching and locking as well as transregional automatic channel recommendation based on vehicle owner habits are fulfilled for the vehicle-mounted radio.

Description

technical field [0001] The invention belongs to the field of vehicle radios, and particularly relates to a method for automatic cross-regional channel change of vehicle-mounted radios. Background technique [0002] Car radios all have the function of locking favorite programs. Usually, the user selects several channels according to their own preferences and locks them in advance through the lock button. As long as different lock buttons are pressed during use, the radio can receive the program of the station. Therefore, , The application of the existing car radio is passive. When the car owner crosses the area, the current radio will have no station, and it needs to manually re-search and manually re-search and lock the station, and the locked station is not necessarily the one that the owner likes to listen to. channel, which brings inconvenience to the owner of the car. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to solve the above-mentione...
