(4) matrix signal transmission channel is designed
Transmission channel design is the electrical design of matrix cable, and transmission channel refers to the physical channel of matrix signal transmission, bag
Containing cable branch design, conductor selection, electric connector type selecting, deconcentrator Selection and Design etc..
The design of matrix signal transmission channel is according to above-mentioned unit traversal order, across cabin scheme, topological structure, matrix resource point
With progress.One matrix is using a cable, user equipment one cable branch of correspondence.
MA1 matrixes link constitutes 1 big cable, and cable branch includes W01, W01-1, W01-2；
MA2 matrixes link constitutes 1 big cable, and cable branch includes W02, W02-1, W02-2；
Conductor loading cable is 0.5A, and electric current is smaller, it is considered to which volume drops in electric current one-level.
The type of electric connector type selecting matrix device end electric connector matching, wire, the selection of deconcentrator should be met
The in-orbit environmental demand of spacecraft, electric current, the temperature drop volume of component should meet I grades of drop volumes.For matrix signal transmission requirement, one
As selection standard density connector transmission signal, such as J14A, D-SUB, J6W type.Deconcentrator is class bus type cable knot
The expansion line element device of structure, realizes that signal wire 1 enters the 2 expansion line functions of going out, structure is as shown in Figure 8.
Specific transmission channel table is as follows, is contained in table：Branch information, signal name, wire gauge, deconcentrator mark
Deng, wherein, deconcentrator identification field has indicated position and the deconcentrator mark of required setting deconcentrator.Set according to above-mentioned input condition
The matrix signal transmission channel table of the example satellite has been counted, 9 are shown in Table.
The matrix signal transmission channel table of table 9
Can be input condition, cable network transmission channel table by traversal order, matrix resource allocation after the completion of the step
For output file, verification input and the uniformity of output reappraise traversal, topology, the feasibility of matrix resource allocation, if
In the presence of very big optimization space, will repeatedly it be designed the step of return above.
(5) matrix cable louding is designed
Cable louding design is completed according to cable network transmission channel table, formation can instruct cable production, colligation, the text laid
Part.The file for instructing cable to produce can be two kinds of forms, and one kind is cable branch length table, and each branch is marked respectively
Cable length on cable between associated electrical connector；One kind is cable louding Prototype drawing, as shown in Figure 9.
In actual design, cable louding design drawing information can be more rich, in place comprising connector information, deconcentrator mark institute
Put.Design is moved towards in satellite instrument device layout, cable system should facilitate equipment installation and the installation and dismounting of cable system, matrix electricity
Cable net layout should facilitate connector plugging and fastening, and cloth should have enough flexibility ratios and appropriate length.Matrix cable system and high frequency
Cable beam splitting is connected up, and away from radiation source.
On matrix cable distribution, generally using the wiring of different colours, colligation differentiation is carried out to different matrix links, just
In recognition detection.Matrix instruction wire in same matrix link answers independent colligation with matrix remote measurement wire, it is impossible to when splitting, close
To be a branch of.For ease of the mounting and installation of matrix cable, the main tree cable of matrix should be unidirectional and move ahead, and forbid cyclization.Matrix cable system
From bifurcation to being less than 300mm on the distance principle of user equipment connector.Matrix cable routing should meet that cabling is most short, electromagnetism
The best condition of compatibility, usual cable beam diameter is no more than 5cm.Cable is every certain length with nylon cable tie banding in structure
On, it is to avoid cabling passes through sharp, coarse and hard edge.Matrix cable should be kept away in shaping, layout, colligation and fixation procedure
Exempt to make wire, terminal and electric connector bear overstress.
Equally, after the step is completed, according to matrix device traversal order, matrix cable transmission channel table, satellite instrument
Device device layout, checks matrix cable louding figure, it is ensured that cable louding is not cyclic, and cable louding is consistent with traversal order, patches
Part, deconcentrator mark are consistent with transmission channel table mark.If it is correct to check result, the cable design is completed.If checked
As a result there is mistake, then the step of returning above, carry out amendment design.The weight of cable can also be estimated according to cable distribution result
Amount and portability, if there is very big optimization space, will return to the 2nd step and are designed repeatedly.
Under the guidance of design philosophy of the present invention, the matrix cable system development and design work of multi-satellite has been smoothly completed
Make, design efficiency is high, product weight is light, cable transplanting is feasible, signalling channel transmission is errorless, is fully verified.Follow-up
