Manned Spacecraft Information Network System

Abstract

The invention provides a manned spacecraft network system, comprising a communication network, a bus control network and a terminal device. The terminal device comprises a wired terminal device and a wireless terminal device; the bus control network comprises a top-layer bus controller and a bus group; the top-layer bus controller is connected with the wired terminal device through the bus group, and is used for sending a control command to the wired terminal device through the bus group, and receiving telemetry information sent by the wired terminal device, through the bus group; the communication network comprises a top-layer switch, an access switch and a wireless access point; the access switch is connected with the top-layer switch, and the wired terminal device is connected with the top-layer switch or the access switch so as to access to the communication network; and the wireless access point is connected with the top-layer switch or the access switch, the wireless terminal device accesses to the communication network through the wireless access point, or the wireless terminal device directly performs communication through the wireless access point.

Description

technical field

[0001] The invention relates to the field of aerospace information systems, in particular to a manned spacecraft information network system. Background technique

[0002] In the prior art, RS485 bus, CAN bus, and 1553B bus are generally used to control the equipment on the device. 1553B bus applications generally include 1553B bus controller (BC) and 1553B bus remote terminal (RT). For high-speed data communication, transmission methods such as RS422 and LVDS are generally used.

[0003] At present, there is generally only one set of 1553B bus in the application of 1553B bus. This method is suitable when there are few devices and simple control information, but it is not suitable for a large number of devices and strict control information requirements. of. At present, high-speed data communication generally adopts RS422, LVDS and other transmission methods. The transmission rate is generally in the tens of megabytes or tens of megabytes, and there is no r...

Embodiment Construction

[0028] The present invention will be described in detail below in terms of specific embodiments in conjunction with the accompanying drawings. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It is to be noted that other embodiments may be utilized or structural and functional modifications may be made to the embodiments set forth herein without departing from the scope and spirit of the invention.

[0029] The invention is an information network system framework for a large-scale manned spacecraft, which is divided into two parts: a control network and a communication network. The control network is composed of the top-level bus controller and multiple groups of 1553B buses, and each group of buses adopts A and B redundant backup. The control network adopts hierarchical topology design, figure 1 The terminal equipment in the system can be composed of different applicati...
