Plug and play method based on SpaceWire

Abstract

The invention discloses a plug and play method based on the SpaceWire, and belongs to the field of satellite-borne equipment self-management. The method includes the steps that firstly, SpaceWire node devices which have access to all ports in a network are detected by utilizing a network manager, the types of the SpaceWire node devices are determined, and the topological relation between the SpaceWire node devices is determined; secondly, if a new SpaceWire node device has access to one port in the network or an original device is pulled out, a route informs the network manager to trigger the network manager to launch topological information updating aiming at the port; thirdly, the network manager has access to all SpaceWire node devices in the network according to the topological relation and reads a service register of each SpaceWire node device; fourthly, source sink types of the SpaceWire node devices are judged according to source sink attributes in service information, corresponding information sink of each information source is found, and therefore source sink matching of all SpaceWire node devices can be obtained. The plug and play method is applied to plug and play of SpaceWire devices.

Description

technical field [0001] The invention belongs to the field of self-management of space-borne equipment, and in particular relates to a plug-and-play method based on SpaceWire. Background technique [0002] Plug and Play, referred to as PnP, is used to quickly integrate peripheral devices without manually installing software drivers. It is commonly used in the consumer electronics industry, such as USB drivers. A USB device can be connected to almost all computers, and Within seconds, the user can use the device. The plug-and-play interface technology can also discover the services provided by the device, such as the Dynamic Host Configuration Protocol (DHCP) used on TCP / IP, and the wireless communication based on the Built-in Service ID Mechanisms. Standards such as Bluetooth and ZigBee. [0003] PnP is currently limited to non-aerospace applications. [0004] SpaceWire is the preferred data bus standard solution for spaceborne high-speed communications in the aerospace fi...

Problems solved by technology

However, although the SpaceWire protocol has the advantages of high speed, fault tolerance, and topology flexibility, and is even compatible with the Ethernet protocol to a certain extent, SpaceWire is still only a communication interface standard adopted by everyone. For a specific task situation, it is still necessary to build and configure the SpaceWire network, usually using customized hardware devices and corresponding software services, and going through the construction, assembly, testing, and launch links

This leads to a very long development cycle for the SpaceWire network

[0005] Therefore, aerospace technology is no longer satisfied with just using a unified interface standard
