Problems solved by technology

But next time when you automatically scan the channels again, the previously manually saved frequency points will be lost again, and you need to manually select the favorite frequency points to save the channels again, which will bring trouble to the car owner.

Embodiment

[0034] Such as figure 1 and figure 2 As shown, a kind of radio storage filter algorithm based on the navigation entertainment system provided in this embodiment sets a low signal strength threshold value during initialization so that most frequency points can be selected. The frequency point signals in the manual storage will be compensated, and then uniformly sorted by intensity, and the best group of frequency points will be selected and stored in the storage list. There are two main bands of navigation radios, frequency modulation (FM) and amplitude modulation (AM). Since the domestic generally listen to FM band radio stations, this method mainly focuses on FM band search, but this method is also suitable for other bands such as radio AM band automatic storage.

[0035] A kind of radio deposit filter algorithm based on the navigation entertainment system that the present invention obtains comprises the following steps:

[0036] (1) Initialization of the radio storage so...

Abstract

The invention discloses a radio set channel storing filtering algorithm based on a navigation entertainment system, and provides two functions of automatic and manual channel storing. When channel are stored automatically, frequency points of previous manual channel storing performed by a vehicle owner is given priority; If the frequency point strength will be increased when channels are stored in a manual channel storing list, whether an automatic channel storing list is full is determined; if the automatic channel storing list is not full, storing is carried out in order; if the automatic channel storing list is full, then the signal strength is compared and then the channel with relatively strong signals is replaced by the channel with relatively weak signals, so that dynamic adjustment of the frequency points according to dynamic frequencies is realized and the frequency point of manual channel storing is given the priority of being firstly stored into the channel storing list; and accordingly, searching a frequency point to repeat the choice of favorite radio stations in a frequency point by frequency point mode through manual channel storing is no longer needed, making the automatic channel storing more user-friendly.

Description

technical field [0001] The invention relates to an automatic station storage filter method for a navigation radio, which belongs to the technical field of automotive electronics and can also be applied to the technical field of mobile communication electronic equipment, in particular to a radio station storage filter algorithm based on a navigation entertainment system. Background technique [0002] A radio is a machine that uses electric energy to convert radio signals and listen to audio signals emitted by radio stations. For example, a car radio is the earliest voice entertainment configuration used in a car, and it is also one of the most common configurations of a car audio-visual entertainment system. Now it is almost There is no car without a radio. The car navigation radio automatically saves channels, and the car owner can select a group of multiple frequency points with the best signal strength in the whole band and store them in the storage list. However, because ...
