Manned spacecraft 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...

AI Technical Summary

Problems solved by technology

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 requirement for mobile communication. The communication rate of this method is not too high, and there is no communication requirement for personnel activities on the spacecraft. It is suitable in certain circumstances, but if the communication rate is required to exceed 100M bps or even Gigabit bps, and there are personnel activity communication requirements on the device, this method is not suitable
