A kind of self-service speculum type successive consultation method and black box system

Abstract

The invention provides a self-service speculum type successive diagnosis method and a black box system, which flexibly cooperate with two recording modes of "diagnosis" mode and "hard trigger" mode, under the remote control of the ground computer, through the computer software interface The self-service real-time diagnosis of the health status of the black box through the endoscope window makes the black box change from "unpredictable" to "quick knowledge at a glance", which ensures the measurability of the internal data flow and the visibility of the status of the black box before launch; It further designs an irreversible "hard trigger" start command, and embeds this command belonging to the telemetry system into the launch process of the control system, effectively participating in the aircraft's pre-launch command set, ensuring that the peep data shows the health of the black box In the case of abnormal state, the launch process can be terminated, which solves the security problem of the black box recording data during the launch process.

Description

technical field [0001] The invention relates to a self-service speculum type successive diagnosis method and a black box system, belonging to the field of aerospace measurement and control. Background technique [0002] The telemetry system is an indispensable part of the spacecraft test, and its performance directly affects the development progress and performance improvement of the spacecraft. The data black box in the telemetry system is the only test method for the aircraft when it is in the launch tube, underwater or returning to the "black barrier" of the atmosphere. The safety performance of the stored data is directly related to the success or failure of the entire test system. With the continuous development of aerospace test technology, the test object and capacity are constantly expanding, and the data security of the telemetry black box is becoming more and more prominent. The high reliability and complete recording of the entire test process has become a key ind...

Problems solved by technology

[0004] When the aircraft enters the launch process, all execution steps are irreversible one-way flow operations. The safety assessment of the telemetry black box in the "black box" state can no longer rely on the readback data after the test is over, and can only rely entirely on the pre-launch The extrapolation of multiple test results brings great uncertainty risk to the success of the test, because once the black box is in the failure mode at this moment, it means the failure of the whole test
