Brief description of the drawings
Fig. 1 is the utility model principle block diagram.
Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit the scope of the utility model.
The utility model can only individually receive circular polarisation satellite letter to solve traditional vehicle-mounted satellite antenna reception system
Number or linear polarization satellite-signal (single vertical polarization), in prior art basis, single circular polarized antenna can be substituted by employing
Dual polarized antenna, and add d GPS locating module and Big Dipper locating module, user can circular polarisation satellite and linear polarization satellite it
Between unrestricted choice, greatly shorten the star time of seeking of system, drive or during the journey to user bring more selection spaces and
The enjoyment of diversification.
The utility model discloses a kind of vehicle-mounted satellite antenna reception system, including control system and equal with control system
Position adjustments motor, DVB modules, attitude transducer, d GPS locating module and the Big Dipper locating module of connection；Position adjustments electricity
Machine connects antenna assembly, and antenna assembly includes the antenna and tuner being connected, and the power splitter that DVB modules include being connected is conciliate
Device is adjusted, demodulator connects the control system, and tuner, power splitter, rotary joint and output interface are sequentially connected；Position adjustments
Motor includes azimuth-drive motor, pitching motor and polarization motor；Antenna uses dual polarization trumpet array antenna.
Positional information is transferred to control system by d GPS locating module and Big Dipper locating module after system boot, and posture passes
The attitude information of sensor detection antenna is transferred to control system, and control system is according to attitude information and d GPS locating module and north
The positional information that bucket locating module is sent is analyzed and processed, and output control pitching azimuth information to pitching motor, makes respectively
It turns to the luffing angle of respective satellite, and output azimuth information makes it turn to the direction pair of respective satellite to azimuth-drive motor
Satelloid, when linear polarization signal is received, polarization motor rotates the relative angle that can adjust tuner and antenna surface, protects
The signal quality highest received is demonstrate,proved, the satellite-signal of the ku wave bands received is sent to tuner (LNB) by antenna surface, and LNB will
Ku band signals are converted to L-band, then the signal of L-band is linked into control system by power splitter, demodulator all the way and carried out
Sampling, calculates signal intensity, so that adjusting position regulation motor goes to the good direction of signal, another way arrives by rotary joint
System Outlet picks top box rf input port, and signal demodulates image by set top box and sound is sent to television set.
Antenna assembly of the present utility model uses dual polarization trumpet array antenna；The satellite-signal of reception is divided into 4 kinds：1, hang down
Straight polarization 2, horizontal polarization 3, left-handed polarization 4, right-hand polarization.Each equipment can only receive wherein one in product technology in the past
Kind signal, 4 kinds of signals can be received simultaneously using dual polarization trumpet array antenna.1 and 2 belong to linear polarization, and 3 and 4 belong to entelechy
Change, here it is so-called dual polarization.
Output information uses doubleway output interface, if user needs 2 receiving terminals, then each receiving terminal connects one
Individual delivery outlet just, without independent plus signal work(again divides handover module, and wiring is simple, and cost reduces.
Complete machine power supply is vehicle power, and power supply connection antenna assembly, power input voltage and operating current are all in accordance with vehicle-mounted
Power Management Design, without individually installing contravariant equipment additional, contravariant equipment is generally DC12V and turns AC220V, and contravariant equipment takes up space, valency
Lattice are expensive, and caused height is pressed with Danger Electric shock risk, and therefore, vehicle power is easy to use, safe, save space, cost is low.Additionally
Provided with Anti-surging and Lightning-stroke Protection Technology, for protecting equipment and circuit behind output of products mouth, mainly include Surge Protector and

The control system that the utility model uses is prior art for single-chip computer control system or PLC control system, control
Mode processed is simple, and programming is convenient.
The satellite TV signal that the utility model can receive has a lot, but radiation pattern is with regard to circular polarisation and linear polarization two
Kind, for example No. nine satellites of culminant star are exactly that circularly polarized signal has 58 programs, the satellite of linear polarization satellite Asia-Pacific 5 has covers section more 300
Mesh (vertical polarization+horizontal polarization), in addition, there is other unlisted satellites, the utility model can be by above circular polarisation (bag
Include left-handed polarization and right-hand polarization) and linear polarization (including vertical polarization and horizontal polarization) all receptions.
Compared with prior art, had the beneficial effect that possessed by the utility model：Cost is low, using the price of an antenna
Can instead before the performance that can be only achieved with 4 surface antennas, but the die cost of antenna is very high, the mould of a surface antenna
Tool expense will be up to hundreds of thousands RMB.Moreover the area of 4 surface antennas, which will arrive greatly, to be received, and control will be more complicated,
Practicality is lost, the surface antenna of the utility model one disclosure satisfy that the performance of 4 surface antennas, considerably reduce cost, save
Installing space, and the linear polarization of all ku wave bands and the signal of circular polarisation can be received, user need to only pay and existing product
Equal price can has the selectivity of more satellites.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
