Embodiment Construction

[0036] The present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0037] The spacecraft matrix signal link is generally composed of five parts: matrix main controller, electrical connector, transmission wire, matrix load, and matrix standby controller, such as figure 1 shown. The matrix cable network is the thick line part in the figure, including electrical connectors, transmission wires (including splitters) and other accessories.

[0038] The matrix signal is generated by the matrix controller. When a row is pulled high and a column is pulled low, a device is driven. The matrix signal of spacecraft utilizes the characteristics of the vertical and horizontal arrangement of the matrix and the intersecting rows and columns. The user equipment is arranged at the intersection of the row and column signals, and the control equipment is arranged at the source and tail of the row and column signals. The source and ...

Abstract

The invention provides a satellite matrix cable network designing method. The satellite matrix cable network designing method comprises the following steps: (1) determining the constitution of a matrix signal link; (2) determining a topological structure of the matrix link; (3) determining a matrix signal traversal sequence of the matrix link; (4) performing matrix signal resource allocation, establishing an interface circuit connection relationship between matrix user equipment to be allocated and a matrix control end, and forming a matrix junction allocation table; (5) performing cable branch design, lead type selection, electrical connector type selection and de-concentrator type selection design to form a cable network transmission channel table; and (6) finishing cable trend design according to the cable network transmission channel table, and forming a file which can be used for guiding cable production, binding and pavement. In the method, the structural design and electrical design of a matrix cable are combined organically, a stand-alone traversal sequence is determined through selection of an optimal cable path, and an electrical signal design is performed on the basis, so that forward and backward movement of the same signal lead between upper and lower equipment on a deck can be reduced effectively, and the weight of the cable is reduced.

Description

technical field [0001] The invention provides a satellite matrix cable network design method, which is applied to the satellite matrix cable network design and belongs to the technical field of electronic circuits. Background technique [0002] The satellite matrix cable network is a part of the low-frequency cable network, which is a low-frequency cable network connecting the matrix controller and the matrix user equipment. The difference between the matrix cable network and the ordinary low-frequency cable network is that its topology is daisy-chain or bus-like or a combination of the two, and the cable form is retractable. During the forward process of the cable, the diameter of the cable bundle shows a trend of gradually decreasing. , at the same time, the weight of the cable is closely related to the traversal order of the user equipment, the matrix signal distribution relationship, and the cable direction. [0003] At present, the contact connection relationship of or...
