Description
Technical field
The invention belongs to communication antenna field, it is related to a kind of flat panel TV antenna tracking signal method and its antenna.
Background technique
With the development of flat panel TV, the television antenna to match with flat panel TV also develops therewith, for common day
Line or be suspended on wall by pendant or by place on the table.If placed on the table, can occupy larger
Space, be not well placed.And be suspended on wall, then need to drill to metope, if TV not close to metope or
If metope of the person near it is not suitable for punching, which can not just be installed.Therefore, the antenna that can be suspended on flat panel TV is answered
It needs and gives birth to.If the patent of Patent No. 201210019482.6 discloses a kind of flat panel TV antenna holder, the bracket includes
Upper at the top of the flat panel TV, support plate aerial platform positioned at platform front end, is hung on the suspension in forward position at the top of flat panel TV
Plate, and with platform rotation connection, be supported in the support portion at the flat panel TV back side.But above-mentioned patent cannot be automatically tracked and be defended
The signal that star TV issues, causes TV signal unstable, although there are also the antenna of automatic tracking signal, without special
The automatic tracking signal antenna that is mounted on flat panel TV on of the door for indoor complex environment.
Summary of the invention
The technical problem to be solved by the invention is to provide a kind of flat panel TV antenna tracking signal method and its antenna,
Indoor complex environment is able to satisfy to avoid the amplitude for touching indoor furniture or adjustment angle excessive and cause gravity center instability.
To achieve the above object, the invention provides the following technical scheme:
A kind of flat panel TV antenna tracking signal method, comprising: set the adjustable region of antenna；Channel signals are lower than threshold value
When, tested rotating platform self-position, so that the signal strength of received terminal current channel is more than or equal to threshold value；In antenna

And when changing the TV signal of the channel after frequency lower than threshold value, antenna can just adjust self-position, the electricity of channel after changing frequency
When being more than or equal to threshold value depending on signal, antenna does not make any adjustment.
In order to avoid tested rotating platform position time too long, therefore on memory module record different channel it is corresponding
Antenna predetermined position, when user's switching channels, the position for adjusting antenna in time reaches predetermined position, accelerates the time of adjustment.
Preferably, antenna corresponding with channel predetermined position more than one is recorded in memory module.
Preferably, when tested rotating platform self-position is according to the sequence of antenna predetermined position typing in logging modle, from newly to
The old antenna that is sequentially adjusted in reaches predetermined position.
Antenna can cause the TV received to be believed when receiving extraneous TV signal due to the variation of satellite and environment
Number the intensity of TV signal that receives than the last time of intensity it is weak, need to record several pre-determined bits in memory module thus
It sets.It is adjusted to another predetermined position again when a predetermined position is unsatisfactory for requiring.
