Abstract

The invention provides an electrical bus applicable to micro satellites, comprising physical topology, working mode and interface definition. According to the physical topology, a power bus and a data bus are connected in parallel and carry out transmission independently. In the aspect of working mode, hot backup is adopted. In the aspect of interface definition, the electrical bus leads out a power signal and a data signal through a three-way electrical connector, and the electrical bus and an on-satellite standalone device are interconnected by the same electrical connector. According to the invention, the power bus and the data bus are integrated on the same electrical connector, the contact is defined as the general cable standard, the design ensures that power signals and data signals are transmitted independently and do not interfere with each other, the complexity of whole-satellite power supply and data transmission is reduced, the degree of product standardization and interface unification is improved, the complexity and weight of a whole-satellite cable are reduced, and the design idea of 'plug and play' for micro satellite electronic products is realized.

Description

technical field [0001] The invention relates to an electrical bus design method suitable for micro-satellites. The electrical bus design method is suitable for the technical field of micro-satellite cable networks and can meet the needs of rapid design and rapid manufacturing of micro-satellites. Background technique [0002] At present, the micro-satellite power signal transmission uses the power bus to carry out successful flight practice on many small satellites abroad. It has the characteristics of light weight and small space occupation. It is in its infancy in China. However, the traditional pure power bus often needs special customization. , Most of them use bus bars, which increases the cost of development. The information transmission on the tiny satellite adopts the data bus technology. Commonly used data buses include MIL-STD-1553B, SpaceWire, RS-232, RS-485, I2C, CAN and other types. The CAN bus has strong anti-interference, high efficiency, The advantage of goo...
