Embodiment 1

[0021] An embodiment of a method for automatically changing channels across regions of a vehicle-mounted radio, see figure 1 and figure 2 , the method includes a cross-regional automatic channel-changing car radio composed of a microprocessor module 1, a positioning module 2 (GPS / AGPS satellite positioning or a base station positioning unit module) and a radio module 3 (FM / AM tuning and AM radio module) In the system, the microprocessor module establishes a radio database in its database memory 1-1, and the radio database includes positioning information in different areas, radio program types in different areas, radio frequency, set signal strength level and preset threshold value ( data in memory using a binary file format), figure 1 The middle communication module 4 realizes the manual locking of the user to the radio favorite program, and the method steps are: at first lock the favorite program according to the user's habit, and set up the favorite program file; its desc...

Embodiment 2

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

Embodiment 3

[0035] Referring to embodiment 1, in this embodiment, according to the user's habits, it is also possible to lock favorite programs and create favorite program files: from the user's first search for stations, the frequency of occurrence of the user's use of different stations within the set time is counted, and the The frequency of different radio stations is represented by F, and then the frequency list of the current storage station is obtained, and 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] Below is the further detailed description to above-mentioned embodiment:

[0037] First of all, the frequency information and station names of radio stations in various...

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 smallerthan 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 listby 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-mounted radios, and in particular relates to a method for automatically changing channels of a vehicle-mounted radio across regions. The method solves the problem of automatically searching and locking stations across administrative regions of the radio through communication positioning, and automatically recommends listening channels according to the habits of car owners. Background technique [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, a...
