ADS-B系统的故障模式、影响及危害度分析(FMECA)

Failure Mode,Effects and Criticality Analysis( FMECA) of ADS-B System

针对空中交通管制领域使用的ADS-B这种新兴设备和技术,根据该系统5年的故障数据,利用故障模式、影响及危害度分析(FMECA)方法,对故障模式进行了统计、分类、原因分析和危害度计算,制定了系统FMECA工作表,指出了该系统的可靠性薄弱环节,为可靠性设计和分析并制定可靠性保障措施提供了依据。

ADS-B is a newly developing equipment and technology applied in ATC field.Statistics,classification,reason analysis and criticality calculation of fault modes have been made,a system FMECA schedule developed and the weaknesses of the system reliability are shown by the method of failure mode,effects and criticality analysis （FMECA） and on the basis of the data of system failures in the last 5 years,serving as the basis on which reliability is designed and protective measures are analyzed and put foward.
