Module unit for satellite

Abstract

The invention provides a module unit for a satellite. The module unit comprises a shell, at least one standard interface and a management module; wherein the standard interface is arranged on the surface, and comprises a power interface for providing power supply transmission, a communication module for realizing data interaction and communication, and a magnetic attraction module for realizing physical connection among different module units. The management module is arranged in the shell and comprises a node self-identification chip which is in communication connection with the power-on interface and is used for identifying other module units connected with the module unit; a wireless module that is used for transmitting backup data in each module unit; a lithium battery module that is electrically connected with the magnetic suction module and is used for providing basic power for the module unit; a power supply management module that is used for managing the power supply of the module units and providing power within 5V; and an electromagnetic unlocking module that is in communication connection with the magnetic attraction module and is used for managing the magnetic attraction module of each standard interface of the module unit.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a module unit for satellites. Background technique [0002] With the continuous development of satellite technology, a single satellite can achieve more and more functions. In order to achieve more functions, the number of subsystems or functional modules configured in the satellite increases accordingly, and the structure of the satellite is more complex. In order to meet the launch conditions, the layout of each module or subsystem is very important. Therefore, this leads to The cost and cycle of satellite development continue to increase. In order to reduce the development cycle of satellites and realize the rapid layout of satellite structures, modular design methods are increasingly used in satellite R&D centers. For example, patent CN106628253 provides a vertebral-column modular satellite platform architecture, which sets standard interfaces on each module of the satel...

Problems solved by technology

[0003] Although the above two satellite structures can quickly realize the design of satellites, the standard interfaces of the module units used are fixed on the designated surface, and the connection between the module units is relatively complicated, which makes it possible to use the module units only Build a satellite of a specific shape, and at the same time, the entire assembly process must be completed on the ground
