Abstract

The invention provides a rule-based programmable 1553B bus system testing method, which comprises the following steps of step 1.concluding a system configuration rule, a message flow sign configuration rule and a message configuration rule of a 1553B bus through analyzing a message transfer mode and a message transfer process of each 1553 bus in a satellite; and step 2.realizing system monitoring, bus communication simulation, data storage and post-processing functions of the 1553B bus in a full testing process of the satellite by a ground testing system through identifying the system configuration rule, the message flow sign configuration rule and the message configuration rule of the 1553B bus. The method can be suitable for various stages of a satellite installation test of each sub-system of the satellite, a whole-satellite test and a large-scale test, and meets the requirements for satellite model research and test.

Description

Technical field [0001] The invention relates to satellite system testing, in particular, to a rule-based programmable 1553B bus system testing method. Background technique [0002] The digital time division system command / response multiplex data bus (ie 1553B bus) is widely used in the development of satellite models due to its strong anti-interference, reliable data transmission, strong real-time performance, and suitable for centralized control. In recent years, with the increasing utilization of the satellite 1553B bus and the increasing complexity of the application function process, it is necessary to monitor and store the 1553B bus data during the entire process of satellite model development and testing, and to replay the stored data when necessary. , Post-processing and other operations to ensure the normal function of the on-board bus. [0003] Generally, some satellites use purchased general-purpose bus monitoring equipment to monitor certain remote terminal sub-addresse...
