Embodiment approach

[0038] Such as figure 2 As shown, according to an embodiment of the present invention, the command transmission method between the spacecraft and the vehicle of the present invention includes:

[0039] S1. Trigger the first command in the mechanical trigger subsystem, and send it to the vehicle and the electrical trigger subsystem respectively;

[0040] S2. The electrical triggering subsystem receives the first command, triggers the second command in the electrical triggering subsystem and sends it to the subsystems in the spacecraft.

[0041] combine Figure 3a and Figure 3b As shown, according to an embodiment of the present invention, the mechanical triggering subsystem 11 is directly triggered by the basic mechanical state of the spacecraft and generates the first command. In this embodiment, the mechanical triggering subsystem 11 uses the electric conductor 111 to pass through different compartments or mechanical components, and the on-off state of the passage throug...

Abstract

The invention relates to a command transmission method between a spacecraft and a carrier. The command transmission method is implemented based on a command transmission system that comprises a mechanical triggering sub-system and an electrical triggering sub-system. The command transmission method comprises the steps of S1, triggering a first command in the mechanical triggering sub-system, and separately sending the first command to the carrier and the electrical triggering sub-system; and S2, receiving the first command by using the electrical triggering sub-system, and triggering a secondcommand in the electrical triggering sub-system and sending the second command to a sub-system in the spacecraft. High reliable command transmission when the spacecraft and the carrier fly normally orescape during an ascent flying phase by using the way of combining the mechanical triggering sub-system with the electrical triggering sub-system. The method provided by the invention has a redundantdesign of dual-channel, multi-touch and multi-command-center, and completely eradicates the hidden dangers of mistakenly transmission and leaking of the commands.

Description

technical field [0001] The invention relates to an instruction transmission method, in particular to an instruction transmission method between a spacecraft and a vehicle. Background technique [0002] The electrical interface between the spacecraft and the vehicle serves as an information exchange channel between the two equipment, used to synchronize the time reference of the vehicle and the spacecraft, and to coordinate various actions of the vehicle and the spacecraft during the ascent flight, usually including the launch A series of command actions such as take-off, weapon and arrow separation, and fairing throwing. [0003] Different from general spacecraft missions, manned spaceflight missions usually design escape systems to ensure the safety of astronauts during the ascent flight. The task of the escape system is to safely return the spacecraft to the capsule and escape from the danger zone of the failure in accordance with the life-saving requirements if a major f...
