Abstract

The invention discloses a determination method for length and number of low-frequency cable conductors of a spacecraft. The determination method comprises the following steps: (1) reading the information of all branches of to-be-processed cables, information of electrical connector pairs and the specification and number information of the conductors used between each pair of electrical connectors in an external cable junction table, and acquiring a cable conductor number table containing the information of all the branches of to-be-processed cables, the information of the electrical connector pairs and the specification and number information of the conductors; (2) acquiring a cable branch length diagram, and compiling structural cable branch length data; (3) working out the length of the conductors between each pair of electrical connectors in each cable. According to the method disclosed by the invention, automatic computation of the length of complicated cables is realized, the workload of manual computation and processing is greatly reduced, the development requirements on high-efficiency and high-quality aerospace products are met, and the problem and the difficulty puzzling the development effort of the low-frequency cables of the spacecraft for a long time are solved, so that the automation level of the development effort of the low-frequency cable products of the spacecraft is further improved.

Description

technical field

[0001] The invention belongs to the field of spacecraft low-frequency cable production, and relates to a method for determining the length and quantity of spacecraft low-frequency cable conductors. Background technique

[0002] The spacecraft low-frequency cable network is an important device to realize functions such as power transmission, command transmission, and information exchange between spacecraft subsystems and equipment or ground equipment. It is the "blood vessel" and "neural network" in the star and ship systems. The quality of spacecraft low-frequency cable network is crucial to the overall performance of the spacecraft and determines the success or failure of the mission, especially for the manned mission, which is related to the life of the astronauts.

[0003] At present, the task of research and development of spacecraft low-frequency cable network products is very heavy. However, traditionally, due to the particularity of spacecraft low-freq...
