Reliability study of the digital rocket-ground signal detection and analysis system

Abstract

The digital rocket-ground signal detection and analysis system is mainly used to remote and local real-time detect and acquire the signals from the key equipments of the control system of the carrier rockets. As a supporting product of the launch vehicles, this system has strict reliability requirements for the hardware and software. With the design of a multi-channel, integrated, real-time detection scheme, the methods of how to improve the hardware and software reliability of the system was discussed. The reliability of related hardware were expected with the method of stress analysis from the component level, unit circuit level, function modules and system-level, and the results show that the reliability of the system is great and can meet the system requirements.
