英文摘要：

In this study on mechanical and electrical equipment signal disposal system fault self-healing,by analyzing the structure,parameters,and typical fault characteristics of signal disposal systems,we evaluate the system decay resistance after establishing a health factor group. By analyzing the biological immunity mechanism,we build a mapping relationship from the immune system to the self-healing system,a model of the fault self-healing system structure based on the immune principle,and introduce the main modules in the model structure and its algorithm. According to the fault self-healing model establishment method,we set up a signal conditioning system model and analyze the system failure. Simulation experiments are carried out to verify its feasibility and effectiveness and the results show that the fault self-healing system for signal disposal based on the immune principle can realize self-healing of the system＇s main faults.
