Description
Technical field
The utility model relates to antenna feed line signal transmission field, particularly shortwave, the transmission of ultrashort feeder, realizes the long distance ionization and the array of feeder transmission.
Background technology
Feeder is a kind of transmission system that the signal of telecommunication that receives on the antenna is transferred to receiver.Feeder commonly used generally adopts coaxial cable, and it is very big to the decay of radiofrequency signal, and general several meters shielded cable just has the decay about 1dB.Under the applicable cases of reality, because antenna is bigger to distance between the receiver, coaxial cable not only attenuation ratio is bigger, and is subjected to other electromagnetic interference easily, makes the degradation of receiver.
Because the close together of transmission is difficult to lay a lot of antennas among a small circle; Adopt common power divider to connect between antenna and the receiver, the switching of signal all is to adopt the mode of joint plug to realize that management of performance is poor.
Summary of the invention
The purpose of this utility model is to provide the transmission system of a feeder, can satisfy antenna to the long-distance transmissions requirement between the radio station, also can carry out informationalized management to antenna system, carries out the switching controls of array between antenna and radio station.
The utility model comprises N channel bank and an array antenna controlled processing unit, wherein 1≤N≤16.Electrooptic conversion module and power module are housed, the photoelectric conversion module that matrix diverter switch, power module is housed in the array antenna controlled processing unit and equates in each channel bank with channel bank quantity.The signal output part of channel bank is connected with the signal input part light signal of photoelectric conversion module, and the signal output part of photoelectric conversion module is electrically connected with the signal input part of matrix diverter switch, and the matrix diverter switch links to each other with computer.
Adopt fiber optic network to carry out remote signal transmission.Aerial signal by channel bank amplification and processing such as filter after convert light signal to, transmit at a distance by fiber optic network.The array antenna controlled processing unit converts light signal to the signal of telecommunication again, by matrix control, sends corresponding radio station to.Matrix switches and control is controlled by computer.
Owing to adopted this new transmission mechanism of Optical Fiber Transmission, make the transmission range of antenna feeding system extend widely, originally tens meters transmission system can reach several kilometers transmission range now.Adopt computer to carry out the control and the status monitoring of array antenna controlled processing unit, realized the informationization and the array control of antenna feeding system.
