Abstract: | In accordance with the software in the field of automatic control,analyses the general characteristics of fault diagnosis part,this paper introduces a fault diagnosis software design method.This method uses a fault tree as the basic logic of causal relationship,making use of distributed computing technology,combining with a variety of failure modes of reasoning, using component technology,and designs and implements a complete fault diagnosis software system with data acquisition, data filtering,and man-machine interaction.The software can be combined with user's knowledge and experience,dynami- cally adjust the parameters according to the characteristics of the fault data acquisition link,balance the accuracy and re- al-time of fault generation and recovery.Combined with flowcharts,the software's human-machine interface can be flexibly configured according to the user's preferences. |
