Description
Technical field
The present invention relates to the antenna assemblies that airborne signal is received and reflected in Civil Aviation System, and in particular to a kind of DVOR omnidirectionals
Beacon reflector net antenna shock mitigation system.
Background technology
DVOR nodirectional beacon reflector nets be in Civil Aviation System with transmitting coordinative composition of equipments it is essential reception and reflect aircraft
The antenna assembly of signal, general construction is on each guidance station on the outside of airfield runway nearby and in flight route, 300 kilometers of spacing
Left and right, the navigation information for providing exact position to aircraft when taking off and on air route, works in very high frequency band, using more
General Le principle provides magnetic azimuth information of the aircraft equipped with relevant device relative to the ground installation.
Existing DVOR nodirectional beacons reflector net is made of 5 parts：
1）Antenna element：Above mesh sheet, it is connected with Antenna Orbit, includes the diameter centered on the mesh sheet center of circle
1 antenna element of 48 uniformly distributed antenna element and center location on 13.5m circumference amounts to 49, acts on navigation signal
Reception and transmitting, generally by company of civil aviaton directly from overseas specialized company purchase；
2）Antenna Orbit：Include the antenna element support column of track and rail superior portion, be used for fixed antenna a period of time, and with it is anti-
Penetrate net connection；
3）Reflector net：The usually steel construction mesh sheet of 26~40m of diameter is about the rule of 1.5*1.5m by several block length * wide
Then mesh sheet is composed, and according to design requirement, diameter can adjust, and act on the reflection of navigation signal；
4）Reflector net holder：To avoid, landform and surrounding obstacle have an impact signal and mesh sheet lower part will install communication
The considerations of computer room, at present generally promotes mesh sheet to certain altitude, crosses steel structure support and top girder steel support mesh sheet and the whole series
Antenna system, the no general hoisting depth of particular/special requirement are 4.5 meters, ensure that signal does not block；
5）Monitoring system：When following any case occurs, monitoring system should have corresponding alarm to indicate, and to control
System and exchange system, which are sent out, accuses general signal, to generate the actions such as change planes or shut down：
A--- azimuth accuracies change more than 1 degree；
B---30Hz reference phase signal level decrease beyond 15%；
C--- subcarriers 9960H:Signal level decrease beyond 15%；
D--- radio frequency power outputs decrease beyond 20%；
E--- identification signals loss is continuous；
F--- sidebands radiate two axisymmetrical antenna failures (Doppler VHF omnirange)；
6）Communications equipment room：Computer room is located near mesh sheet lower central, is mounted on reflector net holder, is set for placing communication
It is standby, concrete computer room is generally used, antenna element passes the signal to communications equipment room by feeder line, since feeder line declines when transmitting signal
Lapse rate is higher, therefore has strict requirements to feed line length, generally should ensure that computer room apex distance off-network piece is not more than 1.2 meters.
The connection type of traditional reflective net antenna mainly causes following two points problem：
1）Track is directly connected to mesh sheet, and trampling during constructing or overhauling be easy to cause Antenna Orbit certain shadow
It rings, causes the shaking and displacement of antenna, influence the precision of aerial signal；
2）To meet the requirement of development of urban planning, reflection net height the more is built the more high, and extreme weather happens occasionally, to reflection
The fixation of the antenna equipment of net causes unprecedented pressure, due to not effective isolation measure, even rigidities such as reflector net, track in addition
It is very big, cause larger vibration frequency and amplitude, and existing antenna equipment requires vibration frequency to should be less than 2HZ, amplitude is less than 1
Degree, thus seriously affects device signal, causes to challenge to the aircraft navigation under inclement weather conditions.
Therefore, there is an urgent need for a kind of novel DVOR nodirectional beacon reflector net antenna shock mitigation systems at present.
Invention content
