在机电装备信号调理系统的故障自愈研究中,通过对信号调理系统的结构特点、参数特性及典型故障特征等进行分析,并建立健康因子群,对系统抗衰性能进行评估.在深入分析生物免疫机理的基础上,建立自愈系统与免疫系统映射关系,构建基于免疫原理的故障自愈系统结构模型,并给出模型中主要模块结构和实现算法.根据系统故障自愈模型建立的方法,建立信号调理系统的模型,分析系统的故障,并对此模型进行仿真实验,验证故障自愈系统模型的可行性和有效性.经仿真实验证明,基于免疫原理构建的信号调理故障自愈系统可以实现其主要故障的自愈.
In the research of fault self-healing of mechanical and electrical equipment signal conditioning system, this paper analyzes the structural characteristics, parameter characteristics and typical fault characteristics of the signal conditioning system and builds a group of health factors to evaluate the anti-aging performance of the system.In the further analysis of biological Based on immune mechanism, the mapping relationship between self-healing system and immune system is established, and the structural model of fault self-healing system based on immune principle is built, and the main module structure and algorithm are given.According to the method of system self- The signal conditioning system model is established, the system failure is analyzed, and the model is simulated to verify the feasibility and effectiveness of the fault self-healing system model.The simulation results show that the signal conditioning fault self-healing system based on immune principle can be Achieve self-healing of its major failures.
