It is higher than three generations's machine in terms of cost, price, while positioning signal is changed for the autonomous north in China from the GPRS positioning of three generations's machine
Struggle against satellite fix, and the satellite-signal incoming frequency actually received does not have any change.
Utility model content
The utility model overcomes the deficiencies in the prior art, there is provided a kind of external Big Dipper signal receiving device.To expect drop
Costs of the low existing three generations's machine user Xiang Si for machine user's transition.
To solve above-mentioned technical problem, the utility model uses following technical scheme：
A kind of external Big Dipper signal receiving device, the device is connected to the tuner for leading to direct broadcasting satellite machine in every family and satellite is straight
Between broadcast system Integrated Receive Decoder；Including：Big Dipper signal receiving circuit module and wave multiplexer；The Big Dipper signal receives electricity
Road module input is used to receive Big Dipper signal；The Big Dipper signal receiving circuit module output end connects the defeated of the wave multiplexer
Enter end；And lead to the tuner output end of direct broadcasting satellite machine described in the connection simultaneously of the input of the wave multiplexer in every family；The multiplex
Device output end connects the signal receiving end of the direct satellite direct broadcast system Integrated Receive Decoder.
Further technical scheme is also to include supplying power for tuner circuit module, and the supplying power for tuner circuit module connects
It is connected between the tuner output end and the wave multiplexer output end.
Further technical scheme is that described wave multiplexer output end passes through coaxial cable and the direct satellite direct broadcast system
The signal receiving end connection of Integrated Receive Decoder.
Compared with prior art, one of beneficial effect of the utility model embodiment is：Product installation of the present utility model
Conveniently, simply, support outdoor that (the self-defined and relative position of tuner) is flexibly installed, there is good anticorrosion and water proofing property
Can, without changing the three generations's machine tuner being used, the cost for purchasing four generations machine integrated tuner again is reduced, makes market
On the old money tuner produced can continue to sell, avoid it from directly eliminating.
