Abstract

The invention provides an efficient satellite SpaceWire Plug-and-Play (PnP) network topology construction method. According to the efficient satellite SpaceWire PnP network topology construction method, construction constraint of a SpaceWire network topology, constraint of nodes in a SpaceWire network, a most time-saving network construction mode of the network traversal and the like are provided. Based on the networking and data transmission characteristics of a SpaceWire bus, time consumed by traversal during initialization of the satellite SpaceWire PnP network is reduced, treatment efficiency of a satellite for coping with sudden failures is increased, design reference and basis are provided for rapid construction of the SpaceWire network on the satellite, and a certain engineering application value is obtained.

Description

technical field [0001] The invention relates to a method for constructing a satellite SpaceWire network, which is used to ensure that the constructed satellite SpaceWire network consumes the least time during network traversal through plug and play in the initialization stage. Background technique [0002] With the rapid development of aerospace technology, the demand for satellite use and load data equipment is ever-changing, and higher and higher requirements are put forward for the dynamic configuration, rapid assembly, testing, and launch of new satellite equipment. provides a good solution. In order to realize the plug-and-play of the satellite SpaceWire network, the master control node first needs to discover the topology structure and connected devices in the network through the network traversal algorithm. If the number of nodes in the network is given, and the master control node uses timing to wait for the response of each router port to determine whether there is...
