Problems solved by technology

[0003] At present, there are no reference materials for the adaptive bus protocol test scheme in China, which leads to the inability to fully verify the adaptive 1553B bus communication function of the new generation of satellite integrated electronic subsystems, which brings difficulties to the effectiveness and reliability of satellite bus communication. certain challenge
The traditional 1553B bus test method can no longer meet the test needs of the adaptive 1553B bus. In order to fully verify the communication function of the communication satellite adaptive 1553B bus, it is necessary to design an accurate and efficient automatic test method and system

Embodiment Construction

[0021] In the present invention, the difference from the conventional communication satellite bus protocol testing method is that, aiming at the self-adaptive 1553B bus protocol communication function, the test scheme is designed from the whole star and sub-system level, and an accurate and efficient automatic testing method and system are built. The dynamic acquisition function of RT self-describing information and the polling function of A / B bus were tested and verified respectively for the adaptive 1553B bus protocol. This test method has been verified for the first time on a communication satellite platform, and the application effect is good. Technical scheme of the present invention mainly comprises two aspects content:

[0022] 1. Use the bus terminal monitoring and processing system to verify the dynamic acquisition function of RT self-describing information from the sub-system level;

[0023] 2. Verify A / B bus polling function from full star using telemetry change be...

Abstract

The invention discloses a method and system for testing a communication function based on an adaptive 1553B bus. The system includes an adaptive 1553B bus simulation and test platform, including a busterminal monitoring and processing system, upper computer software, and a bus interface tester. The bus terminal monitoring and processing system obtains data information of a to-be-tested star management unit, and then performs preprocessing, and transmits the preprocessed data information to the upper computer software. The upper computer software processes the preprocessed data information according to an external instruction, sends the data information to the ground, and controls a star management unit BC end and an integrated business unit to complete the whole star test. The bus interface tester performs the monitoring and testing of the interaction of data information between the bus terminal monitoring and processing system and the star management unit according to an external instruction.

Description

technical field [0001] The invention relates to the professional technical field of bus protocol function testing of a satellite platform integrated electronic subsystem, in particular to a communication function testing method and system based on an adaptive 1553B bus. Background technique [0002] Satellites mainly use 1553B bus, which is a fast serial data bus designed and produced according to the US military standard MIL-STD-1553B. Testing also puts higher demands on it. In the traditional 1553B bus protocol, before the master control terminal (BC terminal) of the upper computer communicates with the remote terminal (RT terminal) of the lower computer, the service information required by the RT terminal needs to be preset in the application software of the BC terminal in advance, resulting in the traditional The bus protocol has insufficient self-adaptability, poor versatility, inflexible data interaction mechanism and bus task cycle. In order to further improve the a...
