Description
Technical field
The utility model relates to wireless communication field, particularly a kind of digital radio signals direction-finding device.
Background technology
Along with the development of information technology, wireless network application in social life more and more widely.Compare with cable network terminal in the past, that wireless network terminal has is mobile strong, be difficult to characteristics such as direction finding location, for the work of wireless direction-finding location brings inconvenience.
Existing directive antenna can be realized the directivity of wireless signal is sent and receives.Utilize the directive antenna characteristic responsive relatively, can judge the direction of signal source roughly the propagation of wireless signal direction.But under and the environment that is interrupted faint at wireless signal, as by the WLAN online, the public WAP (wireless access point) of a plurality of notebooks (AP, Access Point), the signal that has is very faint, and 5-50 has just switched to other people signal in delicate.Like this, generally single directive antenna just can not be realized the direction finding function fast.
The utility model content
At the characteristics of wireless signal in the WLAN environment, the utility model discloses a kind of digital wireless signal direction-finding device, realized the direction finding of radio signal source.
The disclosed a kind of digital radio signals direction-finding device of the utility model comprises Anneta module, signal receiving module, signal processing module and display module.Wherein:
Anneta module is made of the directive antenna more than, is used for receiving wireless signal at wireless communications environment; Signal receiving module, by forming with the equal receiving terminal of described directive antenna quantity, each receiving terminal links to each other with each described directive antenna respectively, is used for receiving wireless signal from described directive antenna; Signal processing module, link to each other with described signal receiving module, be used for the wireless signal that each directional antenna receives is judged, calculate the receiving intensity value of same signal on described a plurality of directive antennas, and with dichotomy judge the wireless messages source side to; Display module shows the judged result of described signal processing module.
Preferably, in the described Anneta module more than an end of one directive antenna on a center of circle, to around arrange radially.
Preferably, described directive antenna more than is divided 360 ° of angles on a plane equally.
Preferably, the quantity of described directive antenna is 2
n, wherein, n is a natural number.
In the utility model, by a plurality of directive antennas are calculated the unlike signal intensity that same signal source receives, judge signal source direction, solved faint, be interrupted the quick direction finding problem under the wireless signal.

Embodiment
As shown in Figure 1, this device is made of Anneta module 1, signal receiving module 2, signal processing module 3 and display module 4.
Wherein, Anneta module 1 is made of a plurality of directive antennas with high-gain.For the ease of calculating direction finding, being placed in of antenna can be in a plane, and an end is on a center of circle, to arranging radially all around.Angle can be identical at interval for it.As shown in Figure 2.
Display module 4 is used for 3 result calculated of shows signal processing module.
The antenna amount of Anneta module 1 can be for greater than any natural number of 1.For the ease of structure and calculating, quantity also can be 4,8,16,32,2
nDeng, n is a natural number.The bundle of lines plane was divided equally in a plurality of days.
For example: the high-gain directive antenna by carrying out five equilibrium in 16 or 32 the same planes, can adopt 2 distributions accurately to measure arrival bearing, realize slewing to small-signal.As shown in Figure 3, be the gain lobe pattern of one of them antenna, signal attenuation is little in the scope of this antenna about 30 ° of angles.
16 antennas are constructed by arrangement mode shown in Figure 4, suppose on the extended line of signal source from antenna 6 and antenna 14 composition line segments.Because the characteristic of directive antenna, having antenna 13, antenna 14, antenna 15 has more intense signal to receive, and antenna 14 may be received stronger signal in theory, but owing to be subjected to the influence of various factorss such as wireless propagation environment, difference is also not obvious.Signal processing module can judge that signal comes from the indicated direction of antenna 14 according to dichotomy.
In sum, device disclosed in the utility model by a plurality of directive antennas are calculated the unlike signal intensity that same signal source receives, is judged signal source direction, solved faint, be interrupted the quick direction finding problem under the wireless signal.
Claims (4)
