附图说明
为了更清楚地说明本发明实施例中的技术方案,下面将对实施例描述中所需要使用的附图作一简单地介绍,显而易见地,下面描述中的附图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的前提下,还可以根据这些附图获得其他的附图。

图3本本发明一实施例提供的一种介质的结构示意图;
图4为本发明一实施例提供的一种设备的结构示意图;
具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚,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。
在本发明实施例中使用的术语是仅仅出于描述特定实施例的目的,而非旨在限制本发明。在本发明实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式,除非上下文清楚地表示其他含义,“多种”一般包含至少两种。
取决于语境,如在此所使用的词语“如果”、“若”可以被解释成为“在……时”或“当……时”或“响应于确定”或“响应于检测”。类似地,取决于语境,短语“如果确定”或“如果检测(陈述的条件或事件)”可以被解释成为“当确定时”或“响应于确定”或“当检测(陈述的条件或事件)时”或“响 应于检测(陈述的条件或事件)”。
现有的设备健康监控预警方法主要采用机理模型+数据模型的原理,发展了设备故障自动发现的能力,但这些系统对故障的识别是0和1的关系,即是非故障和故障的关系,缺乏故障发生前的预警能力,设备健康监控过程不完善。同时,数据模型的创建需要采集大量的数据样本,而现有技术中,这些数据样本需要本领域经验丰富的专家花费大量的时间和精力去采集,分析,之后再建模,整个数据模型的获取,花费了企业巨大的财力物力,导致现有的设备健康监控预警方法只适用于极少数的场合和特定的设备类型,不具备推广的可行性。
针对上述问题,本发明提供了一种设备健康监控预警方法、系统、储存介质和设备。本发明提供的技术方案中,主要通过对设备伴随状态的监控,解决了设备故障发生前的紧急预警问题,为设备零故障运行提供技术保障,具体的,本发明提出建立动态设备故障状态向量库的方法,通过在线自动学习故障发生前一段时间的设备故障状态向量序列,构建故障趋势预警机制,实现提前发现故障趋势、提前预警。其中,方法、系统、介质和设备的实现原理相似,此处不再赘述。
在介绍了本发明的基本原理之后,下面具体介绍本发明的各种非限制性实施方式。
本发明实施例可以应用于各种场景和各种设备类型,用以监控设备的健康状况。需要注意的是,本发明提供的实施例仅是为了便于理解本发明的精神和原理而示出,本发明的实施方式在此方面不受任何限制。相反,本发明的实施方式可以应用于适用的任何场景。
本发明实施例提供了一种设备健康监控预警方法,如图1所示,该方法包括:
S101、实时在线捕获设备故障发生时间点之前的设备状态故障前走势,建立设备故障伴随状态库;
S102、获取设备实时状态走势;
S103、对比设备实时状态走势与设备状态故障前走势;
S104、当设备状态实时走势与设备状态故障前走势接近,且接近程度大于或等于预设指标时,判断为设备即将出现故障,发出故障趋势预警。
本实施例中,所述设备状态包括至少一个维度的设备运行状态数据,此时,所述设备运行状态包括至少一个维度的设备数据,称为设备状态向量,所述状态向量包括设备故障前状态向量和设备实时状态向量。
设设备故障前N(N>1)个连续状态向量构成设备故障前设备状态矩阵,也称设备故障前状态向量序列;设最近的连续N(N>1)个设备实时状态向量构成设备故障前设备状态矩阵,也称设备实时状态向量序列;所述设备故障伴随状态库为设备故障伴随状态矩阵库;所述设备故障伴随状态矩阵库包括设备类型、故障类型、设备故障前状态向量序列,当然,在其它实施例中,设备故障伴随状态矩阵库所包含的不限于此。
本实施例中,设N=30,即设备故障前状态向量序列和设备实时状态向量序列均为长度为30的先进先出序列,当长度大于30时,自动删除序列最前面的状态向量。
S101中,可以采用设备机理模型系统或人工识别设备故障状态,不需要行业专家标定故障起始演化时间点,不依赖故障标本的线下积累,只依赖故障发生时间点,即可实现对设备状态故障前走势的在线获取。
本发明提出的实施例适用于一开始设备故障伴随状态矩阵库为空的场景,随着设备的使用,不断的完善设备故障伴随状态矩阵库,即步骤S101贯穿整个方法的使用,不局限于只用在第一步骤,一旦识别到故障,即收集设备故障前状态向量序列,加入设备故障伴随状态矩阵库。
S102中,采用周期性监控设备实时状态走势,即周期性获得设备实时状态向量,从而获得所需的设备实时状态向量序列,本实施例采用监控时间间隔为1分钟。
S103中,设设备实时状态向量序列为(V 1,V 2,...V N),N>1为序列的长度,设备实时状态向量序列中最后S个状态向量为(V N-S+1,V N-S+2,...V N);
设L={V f}=(V f 1,V f 2,...V f N)是设备故障伴随状态矩阵库中的一个收集设备 故障前状态向量序列;
在S104中,对比设备实时状态向量序列和设备故障前状态向量序列,如果|v N-S+i-v f di|小于预设值,其中1≤d 1<d 2<...<d s<N,则称设备最近S个状态向量落入设备故障伴随状态矩阵库中,当:
S>0时,判断为设备进入故障演进轨迹;
S≥故障预设值,判断为设备即将出现故障,发出故障预警,所述故障预设值可以根据实际情况和需求设定。
当处于故障预警状态,且S=0时,说明故障预警状态得到解除,即设备脱离了故障演进轨迹或者维护人员关停了设备。
本实施例中,令S=3,当然,在其它实施例中,S可以是其它数值;此时,设备实时状态向量序列为(V 1,V 2,...V 30),最后的S个状态向量为(V 28,V 29,V 30),遍历设备故障伴随状态矩阵库中相同设备类型的记录,检查其设备故障前状态向量序列是否包含有(V 28,V 29,V 30),如包含,则发出故障预警。
发出故障预警后,连续跟踪后续状态,持续报警,直到设备实时状态向量序列脱离所有相关故障伴随状态向量序列。

设设备实时状态向量序列为(V 1,V 2,...V N),N>1为序列的长度,设备实时状态向量序列中最后S个状态向量为(V N-S+1,V N-S+2,...V N);
设L={V f}=(V f 1,V f 2,...V f N)是设备故障伴随状态矩阵库中的一个收集设备故障前状态向量序列;
对比设备实时状态向量序列和设备故障前状态向量序列,如果|v N-S+i-v f di|小于预设值,其中1≤d 1<d 2<...<d s<N,则称设备最近S个状态向量落入设备故障伴随状态矩阵库中,当:
S>0时,判断为设备进入故障演进轨迹;
S≥故障预设值,判断为设备即将出现故障,发出故障预警,所述故障预设值可以根据实际情况和需求设定。

  5. 根据权利要求4所述的方法,其中,所述设备实时状态向量序列为(V 1,V 2,...V N),N>1为序列的长度,设备实时状态向量序列中最后S个状态向量为(V N-S+1,V N-S+2,...V N);L={V f}=(V f 1,V f 2,...V f N)是设备故障伴随状态矩阵库中的一个收集设备故障前状态向量序列;如果|v N-S+i-v f di|小于预设值,其中 1≤d 1<d 2<...<d s<N,则判断设备最近S个状态向量落入设备故障伴随状态矩阵库中。
  6. 根据权利要求5所述的方法,其中,当S>0时,判断为设备进入故障演进轨迹;当S≥故障预设值,判断为设备即将出现故障,发出故障预警。
  7. 根据权利要求1所述的方法,其中,设备故障发生时间点由设备故障监控系统发现,或由人工识别发现。
  8. 一种设备健康监控预警系统,其中,包括:
    采集模块,被配置为获取设备状态故障前走势;
    监控模块,被配置为监控获取设备实时状态走势;
    分析模块,被配置为将所述获取设备实时状态走势与设备状态故障前走势对比分析;
    预警模块,被配置为当分析模块判断为设备即将出现故障,发出故障趋势预警。
  9. 一种设备健康监控预警设备,其中,包括:存储器、处理器;所述存储器上存储有可执行代码,当所述可执行代码被所述处理器执行时,使所述处理器执行如权利要求1至7中任一项所述的设备健康监控预警方法。
  10. 一种存储介质,所述存储介质上存储有可执行代码,当所述可执行代码被电子设备的处理器执行时,使所述处理器执行如权利要求1至7中任一项所述的设备健康监控预警方法。
