Satellite signal receiving system generally includes antenna, be in the feed at antenna-reflected center, the tuner that is connected with feed, by the feed that is on the focus electric wave signal conduction that desire receives is flowed to the tuner that is right after thereafter, the effect of tuner is that the small-signal that antenna is received is amplified, will output to terminal through the satellite-signal that amplifies, in direct broadcasting satellite receives, mainly be to use tuner to be used as receiving the main body of satellite audio visual signal, and the limitation of tuner receives when can not well realize many stars multi-user exactly, the tuner that can realize at most at present is that single star 8 users receive use simultaneously, perhaps double star 4 users receive use simultaneously, can not realize that double star 8 users receive use simultaneously, certainly or even more many realization 4 stars receive simultaneously, use when 8 users are above.
Summary of the invention
The utility model has proposed one at above problem and has received two satellite-signals simultaneously and support 8 users even more users to receive the satellite receiving system with variable connector of satellite audio visual signal simultaneously at the Ku wave band.
The technical solution of the utility model is: the satellite receiving system of described expansion output, the outlet terminal that comprise antenna, be in the feed at antenna-reflected center, the tuner that is connected with feed, the receiver that is connected with tuner and receiver delivery outlet connects, it is characterized in that, between tuner and receiver, loaded the variable connector that to realize multichannel output satellite-signal.
The reception tuner that comprises two satellites in the described satellite receiving system, described two tuners have eight road output signal channels, also have eight as the F input termination of the input of variable connector, respectively eight road output signal channels of corresponding tuner.Described variable connector comprises, filter, switch circuit and DISEqc protocol module, each all corresponding filter in F input termination, described filter connects one group of Switch circuit and DISEqc protocol module respectively, and last whole 8 tunnel signalling channels are connected to output signal end.
The beneficial effects of the utility model: in satellite receiving system, added this link of variable connector, realized receiving two satellite-signal programs simultaneously at the KU wave band, then the signal of two satellites is divided into multiple signals and exports simultaneously, to realize supporting that the multi-user receives the satellite audio visual signal simultaneously.
Description of drawings
Fig. 1 is the electronic schematic of the utility model variable connector.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.
Embodiment 1:
The satellite receiving system of described expansion output, the outlet terminal that comprise antenna, be in the feed at antenna-reflected center, the tuner that is connected with feed, the receiver that is connected with tuner and receiver delivery outlet connects, it is characterized in that, between tuner and receiver, loaded the variable connector that to realize multichannel output satellite-signal.Used described KU wave band Application of composite variable connector, two satellite-signal A that can receive two tuners and B carry out selectivity to be handled.
The reception tuner that comprises two satellites in the described satellite receiving system, be decided to be tuner A and tuner B respectively, described two tuners have eight road output signal channels, also have eight as the F input termination of the input of variable connector, respectively eight road output signal channels of corresponding tuner.Each F input termination connects the tuner that corresponding QUATTRO(refers to that a kind of not belt switch switches, can export V/L respectively, H/L, V/H, H/H four road signals) output, be the LNB(tuner) operating voltage is provided, the LNB of two satellites exports eight road signals and has entered F input termination as the input signal of variable connector, described variable connector comprises, filter, switch circuit and DISEqc protocol module, each all corresponding filter in F input termination, described filter connects one group of switch circuit and DISEqc protocol module respectively, last whole 8 tunnel signalling channels are connected to output signal end, the V/L of two satellites, H/L, V/H, H/H totally eight tunnel sets of signals has synthesized a satellite-signal, the signal that each road signal flow is exported after eight filters of variable connector are handled flows into the Switch circuit and carries out hand-off process, described filter is a mixed allocation bank of filters, the major function of this mixed allocation bank of filters is exactly wherein one the tunnel to import satellite-signal, by being assigned to 8 road signals after this mixed allocation bank of filters, and output to 8 output ports respectively through after the filtering, amount to the A of two satellite-signals and eight road signals of B, to be assigned to 64 road signals output altogether, after finishing dealing with like this, to contain four road signals of satellite-signal A and four road signals of satellite-signal B simultaneously on the satellite-signal circuit on the signal line of each output port, eight road signals transmit on a circuit simultaneously altogether.
As shown in the figure, by after the processing of mixed allocation bank of filters, the signal of each road output will be connected to Switch circuit and DISEqc protocol module like this.
Wherein the DISEqc protocol module selects different satellite-signals to distinguish to the user, the break-make of the known corresponding satellite-signal control identification signal of (or as satellite-signal A B) output; Or while Switch circuit is discerned four kinds of different conditions signal V/L, H/L, V/H, H/H of satellite-signal A B again, and discerns the user and select wherein a kind of signal of different conditions, exports one and the known corresponding identification signal of user after the identification.Identification signal of output is through the intermediate frequency amplifier circuit amplification that gains (as V/L or H/L or V/H or H/H), be connected respectively to high pass filter and the 40MHz-862MHz low pass filter of 950MHz-2150MHz again, output to last output port through the signal behind the high pass filter, and will connect the F input termination of variable connector Terr as cable TV signal through the signal of low pass filter.Signal by output port after such signal processing will contain 8 road signals that amount to of two satellite-signal A and B, the user will according to own hobby arbitrarily selection one road satellite-signal accept the satellite audio visual signal.As shown in the figure, we have 8 final output ports, and historical facts or anecdotes has showed the function that 8 users receive the audio visual signal of two satellite-signals simultaneously.
The function of Switch circuit is the signal that the identification user selects four kinds of different conditions, exports one and the known corresponding identification signal of user after the identification.The function of DISEqc protocol module select different satellite-signals to distinguish to the user, export the break-make of known corresponding satellite-signal control identification signal, the identification signal of conducting is through the intermediate frequency amplifier circuit amplification that gains, the high pass filter of 950MHz-2150MHz of flowing through carries out trap through the 40MHz-862MHz low-pass filtering again, and this band frequency is the usefulness of frequency channels of cable TV.Cable TV signal connects the F input termination of variable connector Terr, signal flow into the distributor processes of variable connector, one road cable TV signal one is divided into eight, the synthetic output that is transferred to the F input termination of variable connector of eight road cable TV signals and eight road high pass filter output signals.
