Abstract
The utility model discloses a surface receiver for multiple satellite TV radio signals, which solves the problems existing in the prior art that a plurality of receiving antennas and a plurality of ground receiving stations need to be adopted while multiple satellite TV signals are received. The receiving device adopts many R. F. heads, many waveguides, many feed lines, and many receiving sets to form many receiving units which are arranged on an omnibearing mounting structure assembly. Therefore, a satellite antenna can receive satellite TV signals transmitted by a plurality of satellites. The utility model has the advantages of enhanced antenna utilization rate, low cost, and less installation area.
Description
The utility model relates to a kind of satellite radio signal receiving system.
In the reception of the satellite TV signal of C-band, in order to receive the TV signal that multi-satellite transmits simultaneously, the method that adopts is that corresponding every satellite sets up a satellite ground antenna at present, set up a grounded receiving station, so just make the cost costliness, installation difficulty increases, fabricating yard and environment requirement are increased, especially also to consider the weight capacity of installed surface (normally attic), therefore, bring very big difficulty for the ground reception of multi-satellite TV signal.
The purpose of this utility model is the problems referred to above of existing in the receiving course of existing multi-satellite TV signal ground, and a kind of ground receiving wastewater facility that utilizes the single seat ground-plane antenna to realize receiving simultaneously the TV signal that multi-satellite transmits is provided.
A kind of multi-satellite TV signal of the utility model ground receiving wastewater facility is made up of waveguide, feeder line and the single-channel receiver of a parabolic antenna, multi-faceted mounting bracket assembly, a plurality of tuner, respective number, corresponding tuner and waveguide constitute a plurality of unit, be installed in respectively on the multi-faceted mounting bracket assembly, the satellite TV signal that each unit receives passes through feeder line separately, import indoor corresponding single-channel receiver, distribute to monitor then, thereby realize receiving the TV signal that multi-satellite transmits simultaneously by a satellite antenna.
The parabolic antenna of this device can adopt existing unified reflector antenna, be shaped as circle, feed-forward mode, primary antenna main support and homemade multi-faceted mounting bracket constitute multi-faceted mounting bracket assembly, the primary antenna inner waveguide is main waveguide, main waveguide is that cannelure is tubaeform, paying waveguide is that the garden awl is tubaeform, each tuner and waveguide constitute main, pay the unit, master unit is installed on the main support, pays the unit and is installed in respectively on the multi-faceted mounting bracket of self-control, main, pay the unit and form different receiving angles, received signal is imported indoor single track receiver by feeder line, and monitor is given in reallocation, receives image effect and is not less than 4 grades (pressing φ 3.5M parabolic antenna).
A kind of multi-satellite TV signal of the utility model ground receiving wastewater facility, owing to adopt a plurality of tuners, a plurality of waveguide, many feeder lines and a plurality of receiver to constitute a plurality of receiving elements, thereby can realize receiving simultaneously the TV signal of a plurality of satellite transmissions by a satellite ground antenna, thereby can improve the utilance of antenna greatly, reduced cost, reduced floor space, the failure rate of having avoided adopting many antennas and having caused raises, and the reception to particular satellite is not less than equal aperture antenna list star TV signal receiver simultaneously.
Fig. 1 is the satellite ground reception installation structural representation that the utility model receives three satellite TV signals simultaneously, receives other multi-satellite TV programmes signalling figure similarly.
Below in conjunction with accompanying drawing embodiment of the present utility model being done one specifically introduces.
1 is main antenna among the figure, can adopt Jiangxi instrument plant to produce the 3.5M parabolic antenna, this antenna includes main waveguide 3 and main support 4, main waveguide 3 is installed on the main support 4,2 is main tuner, adopt the C4 of Toshiba (TOSHIBA) type, noise temperature≤35 ° K, 2-1,2-2 is for paying tuner, adopt the good 28 ° of K tuners of (GARDINER) company of the U.S., main waveguide 3 constitutes master unit with main tuner 2, is installed on the main support 4 3-1,3-2 pays waveguide for self-control, secondary tuner 2-1,2-2 respectively with pay a waveguide 3-1,3-2 constitutes a pair unit and is installed on the multi-faceted mounting bracket 4-1 of self-control, and feeder line adopts 75 Ω feeder lines, receiver 5 is the C3 of a Toshiba type, receiver 5-1,5-2 are the C4 of Toshiba type, 6,6-1,6-2 is a monitor.
Adopt above concrete grammar, just can receive the TV signal of 105.5 ° of Asia of east longitude I satellite, east longitude 110.5 ° of Dongfanghong II satellite and 115.5 ° of culminant star V of east longitude satellite transmission simultaneously, image effect is better than 4 grades.
Claims (2)
1, a kind of multi-satellite TV signal ground receiving wastewater facility, comprise a satellite tv antenna, it is characterized in that this device constitutes multiple unit by a plurality of tuners, a plurality of waveguide, be installed on the multi-faceted mounting bracket assembly, form different receiving angles, each unit links to each other with corresponding indoor single-channel receiver by feeder line separately, constitutes a plurality of receiving elements, realizes receiving the TV signal that multi-satellite transmits simultaneously by a satellite antenna.
