Ensure in every optical fiber of optical fiber receiving terminal all fully according to the physical address connection of transmitting terminal, during digital bea mforming, each passage
Weight coefficient must it is corresponding with corresponding channel data calculate, once optical fiber connection error, will cause the channel data of mistake
Correspondence mistake weight coefficient so that digital bea mforming mistake, and be difficult to search guilty culprit, while optical fiber transmitting terminal with connect
Difficulty increases when the one-to-one mode of receiving end physical address also causes debugging.
The content of the invention
It is an object of the invention to provide a kind of phased array TR component channel datas side of being automatically positioned based on Optical Fiber Transmission
Method.
The technical solution for realizing the object of the invention is：Fiber data transmitting terminal in TR components is sending packet
When, optical fiber logical address and packet numbers, each optical fiber logic are added in the frame head of the packet that every optical fiber sends automatically
Address represents the channel number of the corresponding TR components of data of this root Optical Fiber Transmission；Fiber data receiving terminal is after packet is received
Optical fiber logical address is solved from frame head, the corresponding TR components of the data of this root Optical Fiber Transmission are recognized according to optical fiber logical address

Specific embodiment
TR components (optical fiber transmitting terminal) are as shown in Figure 1 with the optical fiber physical connection figure of signal extension set (optical fiber receiving terminal).Its
Include：Signal extension set sends control parameter through path A by optical port 1 to the optical port 1 of R components, and control parameter is also with packet
Form send, the logical address of this root optical fiber is also contains in the frame head of the packet, for determining TR components in antenna surface
Physical location in battle array, so that it is determined that corresponding receiving channel.To another TR component, signal extension set is passed through by optical port 2
Path AA sends control parameter to the optical port 1 of TR components.All data packet format phases sent to TR components from signal extension set
Together, only difference is that the optical fiber logic number included in frame head in packet on per paths is different.When TR components will be received
To signal digitlization after pre-processed, then by optical port 2,3,4,5 via path B, C, D, E or BB, CC, DD, EE to
Signal extension set sends the data of each receiving channel after pretreatment.
As shown in Fig. 2 the optical fiber logical address in the packet that is received according to optical port 1 of all TR components, automatic to calculate
The optical fiber logical address that correspondence optical port 2,3,4,5 should send, forms transmitting terminal optical fiber logical address mapping table.For example, TR groups
The optical fiber logical address that the optical port 1 of part receives in packet is 0, is (x from the position coordinates in the battle array of face0,y0), correspondence day
Line face battle array channel number is 1~No. 8 receiving channel, then the corresponding optical fiber logical address of optical port 2 is 0, shows to be sent through the optical port, nothing
It is the data after the 1st and No. 2 receiving channel acquisition process (assuming that every by the data received by signal extension set via any paths
8 receiving channels of individual TR components correspondence)；The corresponding optical fiber logical address of optical port 3 be 1, show through the optical port send, no matter via
The data which paths is received by signal extension set, are the data after the 3rd and No. 4 receiving channel acquisition process；The corresponding light of optical port 4
Fine logical address be 2, show through the optical port send, no matter the data received by signal extension set via any paths, be 5 and No. 6
Data after receiving channel acquisition process；The corresponding optical fiber logical address of optical port 5 be 3, show through the optical port send, no matter via
The data which paths is received by signal extension set, are the data after the 7th and No. 8 receiving channel acquisition process.The optical fiber of transmitting terminal
Logical address mapping table is that the optical fiber logical address received by transmitting terminal receiving branch (i.e. the optical port 1 of each TR component) determines
, so the correctness of the optical fiber logical address mapping table in order to ensure each TR component, the light of optical fiber transmitting terminal receiving branch
Fine physical connection can not be wrong.
For the receiving terminal (i.e. signal extension set) of fiber data, by optical port 18,21,23,19 RX path B, C, D, E
The data of transmission.As shown in Fig. 2 optical port 18 is through the data after path B the 1st, 2 receiving channel acquisition process of reception；Optical port 21
Data after receiving the 3rd, 4 receiving channel acquisition process through path C；Optical port 23 receives the 5th, 6 receiving channels and adopts through path D
Data after collection treatment；Optical port 19 is through the data after path E the 7th, 8 receiving channel acquisition process of reception.All optical ports are received
To after data, packet alignment is carried out according to the K characters for receiving, then solve the information in packet frame head, obtain the optical port
The reception data of each optical port are ranked up by corresponding optical fiber logical address further according to optical fiber logical address, by transmission path with
Optical port is received to be mapped.So that for rear class treatment, the data of all receiving channels are arranged by optical port mapping order,
It is easy to following digital Wave beam forming to process.As shown in Figure 3.Assuming that the transmitting terminal of signal transacting extension set has used 1 to No. 12 optical ports,
Receiving terminal has used 13 to No. 60 optical ports, corresponds to 12 R components, and 96 receiving channels after the completion of ordering map treatment, can recognize
For No. 18 optical port correspondence receives the path that optical fiber logical address is 1, the 1st, 2 data of receiving channel of the correspondence for receiving；
No. 21 optical port correspondence receives the path that optical fiber logical address is 2, the 3rd, 4 data of receiving channel of the correspondence for receiving；The
No. 23 optical port correspondences receive the path that optical fiber logical address is 3, the 5th, 6 data of receiving channel of the correspondence for receiving；19th
Number optical port correspondence receives the path that optical fiber logical address is 4, the 7th, 8 data of receiving channel of the correspondence for receiving.When by TR
The data that component optical port 2 sends are sent to No. 30 optical port of signal extension set through path C, then signal extension set is according to reception data frame
Optical fiber logical address in head re-starts mapping.This ensure that in the case that actual physics connection is changed, via reflecting
After penetrating sequence, the physical location of the actual TR components of correspondence is corresponded with the weight coefficient of respective channel during digital beam froming.
Which simplify cable connection, system flexibility is enhanced.
