Abstract

The invention provides a system health state assessing method and device. The method comprises the following steps: partitioning functional levels for a device system, and determining the layer structure of a task system to be assessed in the device system; performing failure analysis processing on the task system, and determining a failure node of each layer structure of the task system; determining the health index parameters of each layer structure of the task system according to the failure node of each bottom layer structure of the task system, and test point data of each bottom layer structure of the task system; and assessing and determining the health state of the task system according to the health index parameters of each bottom layer structure of the task system. Through adoption of the technical scheme, the health state assessment for a complex task system with a multilayer structure can be realized.

Description

technical field [0001] The present invention relates to the technical field of system health assessment, in particular to a system health state assessment method and device. Background technique [0002] With the development of industrial technology, the structure of the equipment system in the industrial field is becoming more and more complex, the tasks that can be performed are becoming more and more abundant, and the operating status is more diverse. At the same time, in order to ensure the smooth execution of system tasks, it is increasingly necessary to evaluate the health status of the task system. [0003] The traditional system health status assessment method is usually realized by the fuzzy comprehensive assessment method, but the fuzzy comprehensive assessment method is more suitable for evaluating the health status of simple equipment or simple systems. For complex task systems, due to their complex system structure and more diverse operating states, there is no...
