Description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is gps antenna layout drawing of the present utility model.
Specific embodiment
With reference to specific embodiment, technical solutions of the utility model are further illustrated.
As shown in Figure 1 and Figure 2, specific embodiment of the present utility model is：Build a kind of many gps antennas intelligently switching dress
Put, including：
Gps antenna：Four gps antennas, i.e. the first gps antenna, the second gps antenna, the 3rd gps antenna, the 4th GPS days
Line, the gps antenna are arranged in four dimensional orientations, and in specific embodiment, the gps antenna is biphase in four direction in spaces two
To arranging, bit space undetermined is covered by four direction in spaces.So-called bit space undetermined, i.e. the sky that will be positioned with GPS
Between, the signal of four gps antennas covers whole spaces to be positioned, this assures four gps antenna scattering devices, reaches
Cover to a range of signal.
GPS module 2：Connection radio-frequency (RF) switch 1, connects the gps antenna by radio-frequency (RF) switch 1.
Radio-frequency (RF) switch 1：Connection processor module 3, be connected cooperations with the gps antenna, control the gps antenna unlatching with
Close.In specific embodiment, the radio-frequency (RF) switch 1 is hilted broadsword four-throw radio-frequency (RF) switch.
Gravity sensor module 4：Spatial positional information is obtained, connects the processor module 3.
Processor module 3：Cutting for the gps antenna is determined according to the locus of the gravity sensor module 4 sensing
Interval is changed, the impulsive includes the switching relief area that locus overlap, and controls by the radio-frequency (RF) switch 1 according to impulsive
Make the gps antenna to open and close.
Specific implementation process is as follows：
The position of gps antenna, when being embodied as, is installed first, can be in the four of product corners, this will basis certainly
Designing, its purpose seeks to cover whole space using the radiation direction of four antennas the layout of specific product.
During use, system boot, system processor module 3 persistently read the three-dimensional that the gravity sensor module 4 is obtained
Coordinate information (x, y, z)；When system obtains obtaining position requests, system start-up GPS module 2, while according to the gravity sensitive
Three-dimensional coordinate information (x1, y1, z1) and the rule of setting that device module 4 is obtained, radio-frequency (RF) switch 1 is led to GPS days for setting
Line.
System at regular intervals, reads the three-dimensional coordinate information of the gravity sensor module 4, according to new information
(x2, y2, z2) and the rule of setting, reselects the corresponding gps antenna of unlatching.
After system dormancy, GPS module 2 enters low-power consumption mode, is at this moment no longer read the data of gravity sensor, GPS
Antenna does not also do and switches.
Wherein described gravity sensor module 4 is used for the locus for obtaining positioning product；By the gravity sensor
The data of module 4 a, it is known that spatial state information of product.The gravity sensor module 4 can collect product
Relative position three-dimensional coordinate information (x, y, z), set x, y, z are -10 to 10 numerical value, and precision is 0.1.
Processor module 3 is used for the three-dimensional coordinate information for reading the gravity sensor module 4, controls the radio-frequency (RF) switch
1；Setting rule, for example：When the three-dimensional coordinate information that the gravity sensor module 4 is obtained is in the range of arranging, system choosing
Select certain gps antenna.The coordinates information for arranging certain overlapping range simultaneously forms the relief area of switching, prevents x, y, z value
When near marginal value, system can ceaselessly switch the unstability that gps antenna causes GPS.
In specific embodiment, gps antenna activity is arranged, by multi-direction rotational transform direction, you can with to upper and lower
The direction of left-right and front-back rotates, and by rotational transform direction, is so easy to the gps antenna receiving poor signal time-varying changing-over
Debit to.The gps antenna is fixedly installed, and gps antenna is fixedly installed and need not usually convert gps antenna direction for some
Product, it is ensured that its use quality.
In specific embodiment, the four gps antenna intelligent switching system in automatic navigator is applied.
Double antenna switched system is set in this automatic navigator, to the three-dimensional coordinate information of the gravity sensor module 4
Value setting rule, when three-dimensional coordinate information is (x>5,y<10,z<10) in the case of, the first gps antenna of Systematic selection；Work as three-dimensional
Coordinate information is (0<x<6,y<10,z<10) in the case of, the second gps antenna of Systematic selection；When three-dimensional coordinate information is (- 5<x
<1,y<10,z<10) in the case of, the 3rd gps antenna of Systematic selection；When three-dimensional coordinate information is (- 10<x<-4,y<10,z<
10) in the case of, the 4th gps antenna of Systematic selection；If current data had both met two situations therein, antenna is not cut
Change, can so prevent the situation in some critical points, cause radio-frequency (RF) switch 1 ceaselessly to switch.
Automatic navigator system boot, the MCU of switched system persistently detect the three-dimensional for obtaining the gravity sensor module 4
Coordinate information (x, y, z), when system receives the position requests of automatic navigator, system MCU is by the newest three-dimensional for reading
Coordinate information, such as reading value are (8, -2, -2)；After system reads coordinate information, according to the rule value of setting, in (x>5,y
<10,z<10) in coordinates regional, start GPS module 2, radio-frequency (RF) switch 1 opens the first gps antenna；It is every 1 minute, described heavy
Force transducer module 4 reacquires the three-dimensional coordinate information of automatic navigator；When coordinate information data in (x=5.5, y=2,
When in the range of z=5), the first gps antenna continues to keep it turned on；If during X=4, being switched to the second gps antenna；
After system dormancy, GPS module 2 enters low-power consumption mode, is at this moment no longer read the gravity sensor module 4
Data, gps antenna are not also done and are switched.
This programme can be very good cannot to fix suitable for vehicle-carried mobile navigator position, bad fixation, or even can Jing
Situation about often changing, system can be switched over to gps antenna according to the current practice of product, allow the performance of GPS to locate always
In reasonable state, the Installation Flexibility and Consumer's Experience of product are greatly improved.
It is of the present utility model to have the technical effect that：A kind of many gps antenna device for intelligently switching are built, by arranging four GPS
Antenna, GPS module 2, gravity sensor module 4, radio-frequency (RF) switch 1, processor module 3, processor module 3 are passed according to the gravity
The locus of the sensing of sensor module 4 determine the impulsive of the gps antenna, and the impulsive includes what locus overlapped
Switching relief area, controls the gps antenna by the radio-frequency (RF) switch 1 according to impulsive and opens and closes.This utility model
By the quantity for increasing antenna, the corresponding directivity of antenna is allow to accomplish higher, such that it is able to improve the performance of GPS.One
A little city high rise buildings, where trees are more, increase the gain of 3dB, and the time of GPS location can shorten more than 50%, in addition, fixed
Position precision can also improve.
Above content is with reference to specific preferred implementation further detailed description of the utility model, it is impossible to
Identification is of the present utility model to be embodied as being confined to these explanations.For the ordinary skill of this utility model art
For personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should be all regarded
To belong to protection domain of the present utility model.
