Embodiment

[0054] 1. Extract the wire number information according to the "cable wire contact table", and generate the wire number part of the off-line table;

[0055] (1) Create an empty hash table;

[0056] (2) Read the wire number information

[0057] exist figure 2 Find the start mark of each cable in the contact table shown, and use the word "beginning" in the contact table as the start mark. According to the relationship between the start mark and the cable code, read the row and column where the "cable code" is located to get the "cable code" data. Information related to the electrical connector can be extracted according to the relative position, including the code and specification of the electrical connector.

[0058] (3) Add the cable code, electrical connector information, wire diameter, and quantity to the hash table:

[0059] To read the line where the contact relationship is located line by line, you only need to read the wire diameter and root number information, and...

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...
