Description
Technical field
The utility model relates to satellite signal receiving field, particularly relates to a kind of culminant star No. nine direct broadcasting satellite signal receivers and noise lowering freqyency device thereof.
Background technology
Along with popularizing of China's satellite television, in many areas cannot connecting cable TV, increasing resident can accept satellite-signal viewing TV by the mode of telstar receiver.At present, for the numerous residents of China provide mainly culminant star No. nine satellites of satellite TV signal.Its Ye Shi China first broadcast satellite direct broadcasting satellite.
Current telstar receiver includes antenna, the first-class device of high frequency.Antenna is used for receiving satellite signal, and tuner is by satellite-signal down conversion process.In order to obtain good satellite-signal, not only needing the angle of pitch and the azimuth that adjust antenna, also needing constantly by the position of source feed clip adjustment tuner.But such mode needs constantly to test adjustment, and after adjusting, there is the reception also may destroying satellite-signal during collision.Therefore, how determining the debugging problem of tuner position, is urgently to be resolved hurrily.
Utility model content
The purpose of this utility model is to provide culminant star No. nine direct broadcasting satellite signal receivers and noise lowering freqyency device thereof, to determine the debugging problem of tuner position.
A kind of noise lowering freqyency device, comprising:
Tuner and source feed clip;
Described tuner is fixedly connected with predetermined angle with described source feed clip.
Preferably, described tuner is culminant star No. nine special tuners of direct broadcasting satellite receiving system.
Preferably, described predetermined angle sets according to testing in multiple area the source feed clip position obtained.
A kind of culminant star No. nine direct broadcasting satellite signal receivers, comprise lowering freqyency device as described above.
Preferably, the antenna of described culminant star No. nine direct broadcasting satellite signal receivers and the distance of described lowering freqyency device are preset value.
Preferably, the bore of described antenna is 0.45m.
Preferably, the burnt footpath of described antenna is than being 0.6m.
Therefore, the utility model has following beneficial effect:
In No. nine direct broadcasting satellite signal receivers of culminant star disclosed in the utility model and noise lowering freqyency device thereof, its tuner is fixedly connected with predetermined angle with source feed clip, not needing user when debugging receiving equipment, regulating the position of tuner simultaneously, making the debugging operations simple and effective more of user.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
The structural representation of a kind of noise lowering freqyency device that Fig. 1 provides for the utility model.
Embodiment
Core of the present utility model is to provide a kind of culminant star No. nine direct broadcasting satellite signal receivers and noise lowering freqyency device thereof.
In order to make those skilled in the art person understand scheme of the present utility model better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Set forth detail in the following description so that fully understand the utility model.But the utility model can be different from alternate manner described here to implement with multiple, those skilled in the art can when doing similar popularization without prejudice to when the utility model intension.Therefore the utility model is not by the restriction of following public concrete enforcement.
The utility model discloses a kind of noise lowering freqyency device, see Fig. 1, this embodiment comprises following content:
Tuner 10 and source feed clip 20, its making high frequency head 10 is fixedly connected with predetermined angle with described source feed clip 20.
Certainly, in the utility model, tuner and the mode that is fixedly connected with of source feed clip can be the modes such as welding, bolt connection, in the utility model, do not do concrete restriction.
Usually when installing reception antenna, user need repeatedly to regulate the angle of pitch of antenna, azimuth, source feed clip position to obtain optimum reception effect, debug very loaded down with trivial details.Wherein the angle of pitch, azimuth are relevant with the longitude and latitude of user, must regulate, but the position of source feed clip can by pre-determining according to actual conditions.The utility model is by the source feed clip of antenna and being made of one of tuner, and user does not need the position regulating source feed clip in use, reduces debug time greatly.
The utility model discloses a kind of noise lowering freqyency device, this embodiment comprises following content:
Tuner and source feed clip, its making high frequency head is fixedly connected with predetermined angle with described source feed clip.In a specific embodiment, tuner is culminant star No. nine special tuners of direct broadcasting satellite receiving system.
In a further embodiment, described predetermined angle sets according to testing in multiple area the source feed clip position obtained.Concrete, by different areas actual measurement Received signal strength, record the position of source feed clip during each test.The data in last each area of equilibrium, obtain a best source feed clip position, thus the shell of tuner and source feed clip are made of one.
The utility model discloses a kind of culminant star No. nine direct broadcasting satellite signal receivers, comprise the tuner described in above-described embodiment and source feed clip, its making high frequency head is fixedly connected with predetermined angle with described source feed clip.
