Abstract

The invention relates to a method for realizing data communication between software components forming software under the reuse of on-board software framework, in particular to a static planning-based software bus data communication management method. Software design and data balance load are optimized through decomposition reuse and static planning, and redundant fault-tolerant design is adopted for a message between the software components, so that errors in message transmission can be detected; and process deadlock is avoided through finite retransmission and software restarting, so that the problems of lack of reliability, relatively low timeliness under the condition of large data volume communication, difficult data interaction and low bus utilization rate for a conventional on-board software bus are solved, and the reliability and timeliness of data communication between a software bus framework and the software components are improved.

Description

technical field [0001] The invention relates to a method for realizing data communication between software components constituting the software under the multiplexing of the on-board software framework, specifically a method for managing data communication of the software bus based on static programming. Background technique [0002] The idea of ​​software bus began to appear in the 1990s with the development of middleware technology. The concept of software bus (Software Bus) was first proposed by Purtilo and Suodgras of the University of Maryland in the United States in 1994, and a software bus prototype POLYLITH was described. POLYLITH realizes the integration of heterogeneous components in a distributed environment. [0003] Along with the increasingly large scale and highly complex structure of spaceborne software, different development modes have been launched one after another, and the development and integration mode of the software bus has shown strong vitality. Th...
