Control method of booster switching of gas distribution platform based on high-speed data acquisition

Abstract

The invention relates to a gas distribution bench supercharging switching control method based on high-speed data collection. A pre-launch supercharging mode is firstly adopted in a power measurement and control system. Firstly, front end pressure parameters are received, then by means of data cleaning, smooth filtering, pressure band threshold judgment and a two-out-of-three decision, a supercharging valve on-off signal of a ground gas distribution bench is directly obtained, and a power relay equipment cabinet is used to drive a supercharging valve of the ground gas distribution bench to work, so that the timeliness of data transmission and processing is realized, and the influences of front and rear end network faults are eliminated. According to the invention, three modes of front end self-closed-loop supercharging control (pre-launch supercharging), rear end remote measurement supercharging control (hand-operated supercharging) and rear end geologic measurement supercharging control (test supercharging) are fused by the method, the dependency of supercharging control on the network is substantially lowered, and the system requirements on low-temperature carrier rocket reliable supercharging under various fault modes are met by the multi-mode switching mode, so that the advancement and the practical value are extremely high.

Description

technical field [0001] The invention belongs to the technical field of launch vehicle power measurement and control, is especially designed for a large-scale low-temperature power launch vehicle, and relates to a control method for pressurization switching of a gas distribution platform based on high-speed data collection. Background technique [0002] In the design of the new cryogenic power rocket power system, important design criteria including unattended operation after the start of liquid hydrogen filling / before release, allowing long-term delays in launching capabilities, and simplifying the relationship between the rocket and the ground interface are proposed. These criteria bring With the change of the design principle and operation mode of the air supply and distribution system, the previous manual on-duty method will no longer be applicable to the current launch mode, so it is necessary to adopt redundant design, remote control and other technologies in the air sup...

AI Technical Summary

Problems solved by technology

The new generation of low-temperature launch vehicle has greatly compressed the pre-launch process after propellant filling, and because of the huge cost of the reverse process, it also puts forward higher requirements for the reliability of various functional actions before launch. Its high safety requirements for unattended front-end, the above-mentioned traditional pressurization control methods can no longer meet the requirements of the new generation of cryogenic launch vehicles
