Abstract

The invention provides a method and device for real-time interaction of spaceflight measurement and control data. The method comprises the following steps: acquiring first message data sent by application software of a processor; querying a local subscription/release relation table according to the first message data to obtain information of other processors subscribing the first message data; and sending the first message data to other processors subscribing the first message data according to the queried information of other processors. The high-frequency spaceflight measurement and control data interaction is designed into a subscription-release interaction architecture, the data transmission topology architecture is designed into a non-centralized P2P-based topology architecture, the topology architecture has high expandability, the function of a central server is dispersed to each node, each network node is not divided into a master node and a slave node, and the problems of single-point fault and local network congestion are solved. Based on P2P architecture state message transmission, the method does not pass through any intermediate node, and has high real-time performance.

Description

technical field [0001] The invention relates to the technical field of data interaction of aerospace measurement and control systems, in particular to a method and device for real-time interaction of aerospace measurement and control data. Background technique [0002] With the development of my country's aerospace industry, the complexity of space missions is getting higher and higher, followed by the measurement and control software system becoming larger and more complex, and the data interaction between subsystems is becoming more and more complex. More and more frequently, more and more data formats. A large amount of task data needs to be interacted between various application systems in real time and reliability must be guaranteed for highly reliable data. Traditional message middleware cannot take into account real-time and reliable requirements. Contents of the invention [0003] Aiming at the problems in the prior art, the present invention provides a real-time i...
