Satellite fault diagnosis inference engine system and method

The invention provides a satellite fault diagnosis inference engine system, which is operated based on satellite subsystems and comprises a plurality of subsystem inference modules and a load controller, and any subsystem inference module corresponds to one satellite subsystem and is used for performing inference operation on knowledge rules of the satellite subsystems; and the load controller is in communication connection with the subsystem reasoning module, and is used for obtaining the load pressure of the satellite subsystem reasoning module, adjusting the operation range of the inference engine system according to the load pressure, and controlling the system load. 本发明提供一种卫星故障诊断推理机系统，基于卫星分系统运行，包括多个分系统推理模块及负载控制器，其中，任一分系统推理模块对应一个卫星分系统，用于对卫星分系统的知识规则进行推理运算；负载控制器与分系统推理模块可通信地连接，用于获取卫星分系统推理模块的负载压力，并根据负载压力调整推理机系统的运算范围，控制系统负载。
