Fault diagnosis system of carrier rocket

Abstract

The invention discloses a fault diagnosis system of a carrier rocket. The fault diagnosis system of the carrier rocket comprises a main fault diagnosis microcomputer, an auxiliary fault diagnosis microcomputer, a data processing server, an information display terminal and a network switch. The main fault diagnosis microcomputer, the auxiliary fault diagnosis microcomputer, the data processing server and the information display terminal are all connected with the network switch. The main fault diagnosis microcomputer and the auxiliary fault diagnosis microcomputer carry out fault diagnosis through telemetry data received from relevant systems in real time according to the specific diagnosis mode of a readied segment and a preset criterion. When the main fault diagnosis microcomputer breaks down, the auxiliary fault diagnosis microcomputer is used for completing fault diagnosis and fault display, then launching safety and launching reliability of the carrier rocket are ensured, and the system is easy to implement. The fault diagnosis system of the carrier rocket is successfully applied to fault diagnosis of the readied segment of a manned space flight, and ensures the life safety of astronauts in the readied segment.

Description

technical field [0001] The invention relates to a fault diagnosis system for a carrier rocket, in particular to a fault diagnosis system for a launch stage of a carrier rocket, which belongs to the technical field of fault diagnosis. Background technique [0002] The fault diagnosis of the stage to be launched refers to receiving relevant system test data in real time during the period from "-30min" to "ignition" before the rocket launch, and performing fault diagnosis and display according to the specific fault mode of the stage to be launched according to the predetermined criteria, and the diagnosis results It is provided to commanders and designers at all levels as an important basis for making decisions about launching rockets according to the scheduled time, and is an important guarantee link to ensure the success of the launch mission. At present, the launch vehicle does not have a fault diagnosis system for specific failure modes and criteria during the launch phase....
