Background technique

The integrated business unit of high-orbit communication satellites is space-borne telemetry and remote control equipment, mainly including temperature measurement module, analog quantity collection module, bi-level quantity collection module, matrix command management and drive module, matrix telemetry collection module, load equipment telemetry and remote control two class bus, etc. The device has two working modes, one is the normal mode, in which the device completes data interaction with other onboard devices through the 1553B bus; Complete data interaction with other devices. the

In order to verify whether the function and performance of the integrated business unit meet the requirements of technical indicators, it is necessary to verify the comprehensive function and performance verification of the test equipment. The traditional verification equipment is a separate device, which tests each module and function separately, including temperature acquisition and verification equipment, analog quantity acquisition and verification equipment, and bi-level quantity acquisition and verification equipment. Several functional indicators were tested. The independent verification equipment mainly has the following two problems: 1. Each verification device only tests a few functional indicators, and it takes more time and energy to complete all the tests; 2. Separate tests cannot verify multiple performances Whether there is a correlation between the indicators, for example, it is impossible to test whether the process of sending instructions will interfere with certain telemetry values, so the coverage of the test is not enough, and the problem of functional correlation is left to the whole star testing stage. the

At present, the integrated business unit adopts the integrated module design idea, and the function concentration is high in complexity, so the traditional verification equipment can no longer adapt to the test verification of the current equipment. the
