火箭在飞行过程中经常发生各种故障,因此需要对其飞行状态进行监视、判断,及时有效地做出相应的安全控制决策。在分析原有火箭安控系统的基础上,针对火箭飞行的特点及不确定的规则知识,提出了基于智能决策的火箭安控系统。首先给出了集弹道数据处理和安全控制决策于一体的计算机决策支持系统模型;然后根据安控系统的特点,对安控知识进行分类,给出了安控系统知识不确定的表示方法,形成了相应的安控决策网络;最后以Visual C++6.0为开发平台,构建了安控推理决策模型,给出相应的推理流程。仿真实验表示,该方法能实时监测出火箭的飞行状态,对其进行有效的管理,为安控领域专家的最终决策提供支持。
During the flight, the rocket often has various faults, so it needs to monitor and judge its flight status and make corresponding safety control decisions in time. Based on the analysis of the original rocket safety control system, a rocket safety control system based on intelligent decision-making is proposed for the characteristics of rocket flight and the uncertain rules. Firstly, the model of computer decision support system integrating the data processing and security control decision-making in the trajectory is given. Then, the security control knowledge is classified according to the characteristics of the security control system, and the representation of the security control system knowledge uncertainty is given. Finally, taking Visual C ++ 6.0 as the developing platform, this paper constructs the security control inference decision-making model and gives the corresponding reasoning flow. Simulation experiments show that the method can monitor the rocket’s flight status in real time, manage it effectively and provide support for the final decision-making of experts in security control field.
