Embodiment 1

[0036] figure 1 For the method flow chart of carrying out station search optimization under AM conditions according to the present invention, reference will be made below figure 1 , the method for searching and optimizing the station under AM conditions of the present invention is described in detail:

[0037] Step 101: start searching and obtain stations.

[0038] Step 102: Judging whether the radio station is valid by judging whether the radio station is within the valid range, if valid, proceed to step 103; if invalid, terminate the channel search and optimization process.

[0039] Step 103: Obtain the signal strength Level of the radio station.

[0040] Step 104: Judging whether the signal strength Level of the station is greater than the station stop sensitivity threshold, if yes, adding the station to the playlist; if not, proceeding to step 105.

[0041] Step 105: Obtain the previous station and the next station of the station by stepping forward and backward by 900 ...

Embodiment 2

[0044] figure 2 For the method flow chart that carries out search station optimization under FM condition according to the present invention, will refer to below figure 2 , the method for searching and optimizing the station under FM conditions of the present invention is described in detail:

[0045] Step 201: start searching and obtain stations;

[0046] Step 202: Judging whether the radio station is valid by judging whether the radio station is within the valid range, if valid, proceed to step 203; if invalid, return to step 201, and search again;

[0047] Step 203: Obtain the signal strength Level of the radio station;

[0048] Step 204: Take the average of the signal strength Level of the station and the average value of the signal quality parameter average of the station, and compare the average value with the lock station sensitivity threshold value, if the taken average value is greater than the lock station sensitivity threshold limit, the station is added to the...

Abstract

A channel search optimization method for a radio is disclosed. The method comprises the following steps: (1) judging the frequency of the radio; (2) if the frequency is AM, performing channel search optimization under the AM; and (3) if the frequency is FM, performing channel search optimization under the FM. The method can avoid the problems of channel missing, miscellaneous channels and unstablechannel search due to the influence of hardware and the external environment during channel search.

Description

technical field [0001] The invention relates to a method for optimizing a radio station search. Background technique [0002] A radio is a machine that is constructed of mechanical devices, electronic devices, magnets, etc., and uses electrical energy to convert radio signals and listen to audio signals emitted by radio stations. Also known as radio, broadcasting, etc. The radio in the prior art will always be affected by the external environment and hardware environment during the channel search process, and there will always be problems such as missing channels, miscellaneous channels, and unstable channel searching. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the purpose of the present invention is to provide a solution for optimizing radio station search. The present invention can avoid the problems of missing stations, miscellaneous stations and unstable station searching caused by the influence of hardware and external en...
