Internet of things system for monitoring storage stage state of solid rocket engine

Abstract

An internet of things system for state monitoring of a solid rocket engine in a storage stage belongs to the technical field of rocket monitoring, and is characterized by comprising an intelligent edge monitoring subsystem, a multi-source data fusion subsystem and an intelligent application support subsystem, based on solid rocket engine technical characteristics and storage stage state monitoring service logic, a three-level system structure of an intelligent edge monitoring subsystem, a multi-source data fusion subsystem and an intelligent application support subsystem is used as a framework; according to the invention, through a hierarchical function which is characterized by extensible acquisition of multi-source heterogeneous data, direct-reading-demand-oriented data preprocessing and deep mining-driven supporting design and is oriented to tasks, one-type and multi-style hardware requirements and channel expansion resource requirements can be met, so that the overall level of a state monitoring system and user convenience are improved.

Description

technical field [0001] The invention belongs to the technical field of rocket monitoring, and in particular relates to an Internet of Things system for monitoring the state of a solid rocket motor in a storage stage. Background technique [0002] The solid rocket motor state monitoring technology uses sensors such as strain gauges embedded in the interior or on the surface to test the deformation, vibration, temperature and other responses of the grains, shells, nozzles and other structures in real time, and uses the detected responses to detect the grains, etc. The damage severity of the structure and the safety of the main body of the structure are evaluated. [0003] The Internet of Things is a network structure based on information carriers such as the Internet and telecommunication networks, which realizes information interconnection and interconnection of physical individuals with independent functions. It has been widely used in transportation, industrial manufacturin...
