Description
Technical field
The utility model belongs to wireless communication technology field, more particularly to a kind of for wireless video image delivering system
Combining repeater.
Background technology
Since being born development from the communication technology, due to the ease for operation of radio communication, the high efficiency of transmission, low cost, nothing
Need laying-out, be easy to the good characteristics such as rapid construction, be increasingly becoming a kind of wide variety of communication technology scheme, practical application
In, to extend the distance of network transmission, generally realized by the way of being forwarded to data-signal, and repeater is to online
Signal on road has the function of amplification regeneration, is usually used in the conveying length of extended network, its simple, easy to use, valency of installation
Lattice relative moderate, not only acts as the effect of extension network distance, can also be by the network connection of different transmission mediums together.This
Outside, in a wireless communication system, also usually the multiple signals combination of the same frequency range of input or different frequency range is existed using combiner
Together, by synthesis, signal output, into same set of network distribution system, can not only change the data on combiner both sides all the way
Speed, and combiner only needs to an antenna output, has saved antenna resources and base station construction cost.Applied to radio communication
The repeater of technology is developed rapidly with combiner, is referred in scientific research, radio remote away from figure biography, unmanned plane, emergency communication
The field such as wave to be widely applied.Therefore, repeater of the research with combining function is very necessary and important.
In existing wireless communication relay scheme, for reply long-distance transmissions, combiner is usually added using repeater
Transmission plan, be typically required to that repeater is first installed, by realizing combining function after relay forwarding again according to resource constraint,
The multiple signals for relaying output are combined, exported on an antenna.
Developed swift and violent wireless video image transmission technology extensive use, in actual applications, such as unmanned plane in recent years
Remote inspection, the ecological monitoring in remote mountain area, water head site monitoring, telecommunication speedily carry out rescue work commander etc. purposes when, generally require
Repeater is added to improve the operating distance of wireless image transmission system, especially in the more complicated mountain area of some geographical situations, massif
Etc. various block the transmission range of wireless image transmission system can be caused to shorten, repeater just seems even more important.And to recipient
Speech, while receiving transmission data from multiple emitters needs numerous antennas, and if receiver design is unreasonable, go back
Image-receptive quality can be influenceed, combiner just turns into the only selection for solving the problem, can be combined as multiple signals to connect all the way
Receive.Technology application means now are mostly using first installing repeater, then to install the scheme for combining of combiner, it is necessary to frame simultaneously
It is higher to number of devices and manual debugging, maintenance requirement if repeater and combiner.
For the defect problem for solving above-mentioned wireless image transmission system repeater, combiner separation is caused, at present, partly adopted though having
It is typically that design is more according to the investigation data analysis to application regional geography environment with the scheme of change repeater and combiner
For rational relaying layout, the region overlay of no blind spot is reached as far as possible, while by combiner design near relaying, or even put
Together.
Existing wireless video image delivering system repeater and combiner scheme, by optimizing layout, will even relay
Device is placed in same position to reduce manual debugging, maintenance cost with combiner, however, the program is not a kind of really to have conjunction
The repeater of road function, is not that same apparatus has relaying and combining function concurrently, is substantially still a kind of function of separation, will
Two kinds of function device splicing assemblings.
Therefore, in the urgent need to studying a kind of be easily installed, truly available for wireless video image delivering system
Repeater with combining function.
