附图说明
为了更清楚地说明本发明实施例的技术方案,下面将对本发明实施例的描述中所需要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅仅是本发明的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动性的前提下,还可以根据这些附图获得其他的附图。

具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
如图1所示,本发明实施例提供一种设备失效率的确定方法,包括如下步骤:
S101,根据综合模块化航空电子系统中每种设备类型的重要度值、复杂度值、维修值、测试值,确定每种设备类型的分配失效率。
其中,综合模块化航空电子系统的设备可以包括:通用处理模块、电源 控制模块、交换模块、远程数据集中器、机柜、开关等,本实施例对此不做具体限定。
需要说明的是,由于综合模块化航空电子系统是交联系统,设备间关系较复杂,其架构图见图2。其中,综合模块化航空电子系统包含:GPM(General process module,通用处理模块),其主要完成系统的数据计算功能;PCM(Power control module,电源控制模块),其主要完成系统的功率转换及电源输出控制、风机控制等功能;SWM(Switch module,交换模块),其主要完成系统数据转发传输功能;RDU(Remote data concentrator,远程数据集中器),其主要完成系统数据转换功能;机柜,其主要完成系统设备交联和风扇等功能;开关,其主要完成系统的开关功能。
由于,综合模块化航空电子系统串并联模式混合,并且对不同驻留应用,使用的GPM也不相同,分析复杂,不便于工程实践。考虑后续进行可靠性预计时会输入设备的可靠性指标,本实施例将IMA系统按照串联模型进行建模,对于所有的并联模型均按照串联模型进行化简。其可靠性模型的如图3所示。
IMA系统的可靠性R s为各设备的乘积,即:
R s=R n1·R n2·R n3·R n4·R n5·R n6
各设备的可靠性
Figure PCTCN2022075835-appb-000001
则为:
Figure PCTCN2022075835-appb-000002
分配失效率λ作为设备可靠性的另一个基本参数,其度量方法通常为:在规定的条件下和规定的时间内,产品的故障总数与同一时间内累积的工作时间之比。例如,比如一台机器在27度(规定条件)从今天开始连续运行 1000天(规定时间)共运行10000小时(累计工作时间)设备产生故障两次,则分配失效率λ=2/10000。
平均故障间隔时MTBF作为设备可靠性的一个基本参数,通常针对可修复设备。其度量方法为:在规定的条件下和规定的时间内,产品累积的工作时间除以同一时间内的故障总数。由此得到,分配失效率λ与平均故障间隔时MTBF关系为:
Figure PCTCN2022075835-appb-000003
由于综合模块化航空电子系统中的设备为电子设备,因此假设其失效率函数为指数函数,其失效率R s(t)为:
Figure PCTCN2022075835-appb-000004
由R s=R n1·R n2·R n3·R n4·R n5·R n6可得
Figure PCTCN2022075835-appb-000005
Figure PCTCN2022075835-appb-000006
则可知系统失效率λ s为:
λ s=λ n1n2n3n4n5n6
各设备类型的分配失效率
Figure PCTCN2022075835-appb-000007
为:
Figure PCTCN2022075835-appb-000008
其中,N为对应设备类型中的数量,i即代表对应的设备类型,本实施例中的设备类型的数量可以为6,即包括通用处理模块、电源控制模块、交换模块、远程数据集中器、机柜、开关,6种设备类型。
在本发明提供的一个可选实施例中,根据综合模块化航空电子系统中每种设备类型的重要度值、复杂度值、维修值、测试值,确定每种设备类型的分配失效率,包括:
S1011,针对每种设备类型的重要度值、复杂度值、维修值、测试值, 确定对应设备类型的第一分值。
在本实施例中,重要度值、复杂度值、维修值、测试值可以按照1-10分进行评分。其中,重要度值用于表示设备的重要程度,对于重要度值的评估,可按照开发保证等级进行评分,开发保证等级从A-E,A-E按照10-1进行逐级分配,A为10,B为8,C为6、D为4,E为2,按照每级两分的间隔进行逐级降低,同等级的设备重要度值按照实际项目难度进行衡量;复杂度值用于表示设备的复杂程度,复杂度值的评分按照设备的数量进行评分,以设备数量最多的数目作为基准,进行统一化衡量,设备数量越多则对应的分值越低,相同数量的设备以开发保证等级越高的得分越低;维修值的评分,以预估维修时间作为基准进行,维修时间越长则得分越低;测试值的评分,以故障检测时间为基准进行,检测时间越长则得分越低。
具体的,本实施例可以首先确定每种设备类型的重要度值、复杂度值、维修值、测试值,如表1中列出了重要度值、复杂度值、维修值、测试值分别对应的分值,然后对于每一行的数据进行相加,得到对应设备类型的第一分值,如表1中GPM的第一分值为38,SWM的第一分值为35。
表1
Figure PCTCN2022075835-appb-000009
S1012,对所有设备类型的第一分值进行累加,得到系统第一分值。
如上表1所示,本实施例对所有设备类型的第一分值进行累加,得到系统第一分值为38+35+40+17+18+29=177。
S1013,通过计算每种设备类型的第一分值分别与所述系统第一分值的比值,得到每种设备类型的第一指标分配系数。
如表1所示,各设备类型的第一分值为M 1-M 6,设IMA系统分配的系统失效率为λ s或者MTBF s,二者可以相互转换。令:
Figure PCTCN2022075835-appb-000010
则第一指标分配系数为:
Figure PCTCN2022075835-appb-000011
S1014,通过计算每种设备类型的第一指标分配系数分别与系统分配失效率的乘积,确定每种设备类型的分配失效率。
具体的,可通过下述公式表示表1中各设备类型的分配失效率:
Figure PCTCN2022075835-appb-000012
进一步的,在通过计算每种设备类型的第一指标分配系数分别与系统分配失效率的乘积,确定每种设备类型的分配失效率之后,还可以针对每种设备类型的分配失效率和设备数量的比值,确定对应设备类型中各个设备的分配失效率。
具体的,可通过下述公式计算各个设备的分配失效率:
Figure PCTCN2022075835-appb-000013
其中,N为对应设备类型的设备数量。λ k为具体设备的分配失效率。
R(t)=e -λt
由于失效率相乘等于指数的相加,也即是失效率的相加,因为具体设备的失效率均为一样的,所以具体设备的分配失效率为对应类型设备的分配失效率的均值。
S102,将分配失效率小于对应的预估失效率的设备类型,确定为目标设备类型。
对于设备的预估失效率,可按照供应商提供的预计或者随项目进展提供的λ ki预估(i=1,2…,6)进行可靠性预估,则各设备类型的预估失效率为:

其中,
Figure PCTCN2022075835-appb-000015
为某个设备类型的预估失效率,n i为对应设备类型中的设备数量,λ ki预估为对应设备类型中设备的预估失效率;
由此,IMA系统的预估失效率λ s预估为:

具体的,本实施例将各设备类型的分配失效率与预估失效率进行比对,若
Figure PCTCN2022075835-appb-000017
则将其排除在优化序列(无需重新确定失效率),若

则需要进行可靠性优化,即将分配失效率小于对应的预估失效率的设备类型,确定为目标设备类型(需要优化的设备类型)。
设共有L(L≤6)种设备类型需要重新确定失效率,对需要重新确定失效率的设备类型的分配失效率进行按照由低到高重新排序记为

然后根据排列顺序依次重新确定目标设备的失效率。
S103,根据目标设备类型的重要度值、成本值、时间值、质量值,分配失效率和对应的预估失效率,重新确定目标设备类型的失效率。
其中,对于目标设备类型的重要度值、成本值、时间值、质量值,可按 照1-10分进行评分,对于不需要重新确定失效率的设备类型记得分为0。具体的,对于重要度值的评估,按照开发保证等级进行评分,开发保证等级从A-E,按照每级两分的间隔进行逐级降低,同等级的设备评分按照实际项目难度进行衡量;成本值的评分按照预估降低失效率所需要的成本进行评分,成本越多则得分越低;时间值的评分,以预估提升可靠性所需的时间作为基准进行,时间越长则得分越低;质量值的评分,以提升可靠性是否会增加系统质量为基准进行,质量增加越多则得分越低。
