Power measurement and control method and system for liquid carrier rocket

Abstract

The invention discloses a power measurement and control method and system for a liquid carrier rocket, and the system comprises a PLC measurement and control combination which is connected with a ground controlled object corresponding to an on-rocket power system, and is used for obtaining the measurement parameters of all stages of the ground; the measurement and control rear-end device is connected with the PLC measurement and control combination, is connected with an on-rocket controlled object corresponding to the on-rocket power system through the measurement system, and is used for indirectly acquiring on-rocket telemetry parameters of the on-rocket controlled object at each stage from the measurement system; a corresponding first ground control signal is determined according to the telemetry parameters of each stage on the rocket and the measurement parameters of each stage on the ground, and the corresponding first ground control signal is transmitted to the PLC measurement and control combination; the PLC measurement and control combination is connected with a ground controlled object through the relay combination, and the PLC measurement and control combination is used for controlling the on-off of the relay combination in the corresponding stage according to the first ground control signal of each stage, and further controlling the ground controlled object to be matched with the rocket in each stage.

Description

technical field [0001] The present application relates to the field of aerospace technology, in particular to a method and system for power measurement and control of a liquid launch vehicle. Background technique [0002] Rocket launch is a complex and precise work that requires the cooperation between the rocket body and ground equipment. Taking liquid propellant filling before rocket launch as an example, the ground equipment needs to provide the rocket with the right time, quantity, and quality assurance in accordance with the control requirements. There are a lot of information interaction links during the completion of propellant filling, leaking, discharge, withdrawal, etc. Since the information interaction links are controlled by many control systems, the degree of integration is not high. Therefore, in order to prevent rocket launch accidents due to system coordination problems, it is necessary to develop a safe, reliable and highly integrated power measurement and c...
