Abstract: In order to make the health monitoring system suit for the distributed architecture multi engine of the propulsion system in manned spacecraft, and improve its reliability, the distributed component object integrated method was adopted The modifying and decision making algorithm among components was given A prototype system in health monitoring for propulsion system in a manned spacecraft was developed The simulation results indicate that the new method is more suitable for the distributed system than the traditional Object Oriented Programming (OOP) It is an effective method for the health monitoring for the propulsion system of a manned spacecraft

Key words: Spacecraft propulsion;Engine failure;Fault detection;Distributed architecture

摘要： 为了适应载人航天器推进系统多发动机的分布式结构 ,提高健康监测系统的可靠性 ,应用组件技术构造了分布式多智能组件集成的健康监测系统 ,给出了组件之间的协调修正和决策算法。原型系统仿真结果表明 ,该技术比传统的面向对象 (OOP)技术更适用于分布式系统 ,可应用于载人航天器推进系统的健康监测。
