如本文中使用的,术语“包括”及其变型表示开放的术语,含义是“包括但不限于”。术语“基于”表示“至少部分地基于”。术语“一个实施例”和“一实施例”表示“至少一个实施例”。术语“另一个实施例”表示“至少一个其他实施例”。术语“第一”、“第二”等可以指代不同的或相同的对象。下面可以包括其他的定义,无论是明确的还是隐含的。除非上下文中明确地指明,否则一个术语的定义在整个说明书中是一致的。
本公开提出了一种利用生产排程系统文档、产品设计规格文档以及工厂中的数据采集自动化控制系统采集的数据来自动给数据加标签的方法。根据本公开的方法,基于数据采集自动化控制系统所采集的数据得到表示数据的状态特性的数据模型,并将所确定的数据模型与基于生产排程系统文档和产品设计规格文档所生成物联网模型进行匹配,来补充数据的上下文信息,根据匹配结果可以确定生产订单的状态,例如当前设备加工的产品和订单号等。通过这样的方案,减少了对数据进行标记的成本,使得生产更加高效,并且可以帮助管理者了解工厂的生产状态,辅助进行生产排程。
现在结合附图来描述根据本公开的实施例的生产订单状态的监控方法和装置。
图1是示出了根据本公开的一个实施例的监控工厂生产订单状态的方法100的示例性过程的流程图。
在图1中,首先在方框S102中,基于生产排程系统文档生成至少一个生产物联网模型(下文中也称为生产IOT模型)。
生产IOT模型是用于表示生产订单的生产状态的模型。具体地,可以针对所述生产排程系统文档中的每一个订单号生成一个生产IOT模型。
如图3是示出生产IOT模型300的一个具体示例的示意图。图3所示的生产IOT模型300是关于生产订单301为04001180301的IOT模型。IOT 模型中可以包括:订单号302为04001180301;开始时间303例如为4月8日304;结束时间305为4月18日306;该订单包括的工艺有C14、C03和C07;其中307表示下一个工艺,即C14的下一个工艺是C03,C03的下一个工艺是C07,308表示前一个工艺。
在一个示例中,可以根据SCADA(Supervisory Control And Data Acquisition,数据采集与监视控制)系统描述文件来生成生产IOT模型。也可以由操作人员手工设置。针对不同的生产线,可以设置不同的生产IOT模型,例如包括不同的对象属性以及属性之间的关系和对象之间的关系。
接着,在方框S104中,基于产品设计规格文档生成产品物联网模型(下文中也称为产品IOT模型)。
产品IOT模型是用于表示产品的生产工艺信息的模型。产品IOT模型可以确定生产线的重要元数据来得到生产的特征信息。
在根据本公开的方法中,所生成的生产IOT模型和产品IOT模型都包括产品加工的工艺这个属性,通过工艺属性可以将两个IOT模型关联起来。
产品IOT模型例如可以从软件设计工具、例如PLM(产品生命周期管理)、EPLAN等,提取产品元数据,基于元数据来生成产品IOT模型。
产品设计规格文档的具体格式例如可以是表格文档、XML文档、CVS文档等。
在一个示例中,产品设计规格文档可以是表格型文档,对于这种表格型文档,可以用产品设计规格文档的每一列表头作为所述产品IOT模型的属性,用每一列的值作为所述产品IOT模型的属性的值,来生成产品IOT模型。
接下来,在方框S106中,针对生产IOT模型,找到与其具有相同工艺属性的产品IOT模型进行关联。
通过将生产IOT模型和产品IOT模型相关联,可以从这两个IOT模型中的属性值确定关于生产订单的多种具体信息,例如当前设备加工的产品和订单号等。
接下来,在方框S108中,对由工厂中的数据采集自动化控制系统采集的生产设备的数据进行学习来得到表示产品的加工步骤的数据模型。
其中,所述数据采集自动化控制系统例如可以包括但不限于以下中的 至少一项:振动传感器、电流传感器、温度传感器、湿度传感器等,利用这些传感器来采集所述生产设备的数据。
其中,例如可以利用数据的三个维度:数据的改变时间、数据的改变周期和数据的幅值中的至少一项,采用数据聚类引擎对数据进行学习。数据聚类引擎可以标注传感器数据的事件并进行分析得到数据模型,该数据模型可以表示产品的加工步骤。
本领域技术人员可以理解,还可以通过统计的方法或者机器学习方法,对监测得到的数据进行统计分析或者机器学习,从而获得数据模型。此外,在数据分析或者机器学习过程中,可以根据用户的反馈对所采用的规则和参数进行更新,进而更新数据模型。
最后,在方框S110中,将所述加工步骤与所述产品IOT模型中的工艺属性进行匹配,基于匹配结果确定工厂的生产订单状态。
具体地,例如可以通过以下过程来将所述加工步骤与所述产品IOT模型中的工艺属性进行匹配。
首先在产品IOT模型中搜索是否存在与数据模型中的加工步骤的数据同时改变、具有相同的周期或者相同的幅值的变量,如果存在这样的变量,则可以认为产品IOT模型与数据模型匹配,可以根据生产IOT模型和产品IOT模型中的属性值确定当前设备加工的产品和订单号。
如果在产品IOT模型中没有找到与该数据模型有直接联系的变量,则可以将产品IOT模型与基于其他传感器采集的数据所获得的数据模型进行匹配,直到对所有基于不同传感器数据所获得的数据模型都进行匹配。
如果没有找到匹配的变量,则可以反馈不存在必要的数据。
根据本公开的监控生产订单状态的方法,可以将工厂生产中的原始数据与生产过程进行匹配,来确定工厂的生产状态,例如订单的状态、设备的状态等。减少了对数据进行标记的成本,使得生产更加高效,并且可以帮助管理者了解工厂的生产状态,辅助进行生产排程。
图2是示出了根据本公开的一个实施例的监控工厂生产订单状态的装置200的示例性配置的框图。
如图2所示,监控工厂生产订单状态的装置200包括:生产IOT模型生成单元202、产品IOT模型生成单元204、物联网模型关联单元206、数 据模型获得单元208和订单状态确定210。
其中,生产IOT模型生成单元202被配置为基于生产排程系统文档生成至少一个生产IOT模型,所述生产物联网模型至少包括产品加工的工艺属性。
产品IOT模型生成单元204被配置为基于产品设计规格文档生成至少一个产品IOT模型,所述产品物联网模型也至少包括产品加工的工艺属性。
物联网模型关联单元206被配置为针对一个生产物联网模型,找到与其具有相同工艺属性的一个产品物联网模型进行关联。
数据模型获得单元208被配置为被配置为对由工厂中的数据采集自动化控制系统采集的生产设备的数据进行学习来得到表示产品的加工步骤的数据模型。
订单状态确定单元210被配置为将所述加工步骤与所述产品物联网模型的工艺属性进行匹配,基于匹配结果确定工厂的生产订单状态。
其中,所述生产IOT模型生成单元204进一步被配置为:针对所述生产排程系统文档中的每一个订单号生成一个生产IOT模型。
其中,所述产品IOT模型生成单元206进一步被配置为:从软件设计工具中提取产品元数据,来生成所述产品IOT模型。
其中,订单状态确定单元210进一步被配置为:如果所述数据模型中的加工步骤的数据变化与所述产品物联网模型的加工属性相匹配,则根据所述生产物联网模型以及所述产品物联网模型来确定当前设备加工的产品和订单号。
其中,所述数据采集自动化控制系统包括振动传感器、电流传感器、温度传感器、湿度传感器中的至少一项。其中,所述数据模型获得单元208进一步被配置为:基于数据的改变时间、数据的改变周期和数据的幅值中的至少一项,采用数据聚类引擎对所述数据进行学习,来得到表示产品的加工步骤的数据模型监控工厂生产订单状态的装置200的各个部分的操作和功能的细节例如可以与参照结合图1描述的本公开的监控工厂生产订单状态的方法100的实施例的相关部分相同或类似,这里不再详细描述。
在此需要说明的是,图2所示的监控工厂生产订单状态的装置200及其组成单元的结构仅仅是示例性的,本领域技术人员可以根据需要对图2 所示的结构框图进行修改。
下面结合在SME(小中型)工厂中追踪订单状态的一个具体示例来说明根据本公开的方法的应用。
传统的机床通常没有任何数据接口用于远程控制和状态检查。因此,无法在这种机床上直接追踪订单状态。但是可以安装一些传感器来使得机床的工作状态透明化。例如,电流传感器、振动传感器、温度传感器、湿度传感器等。
下面的表1是从订单管理系统得到的一个生产排程系统文档。
Figure PCTCN2019108241-appb-000001
表1
从表1可以看到,订单号为04001180301的这个订单具有3个工艺,C14、C03和C07。从生产排程可以了解某个时间点,机床在哪个工位工作等信息。
基于表1,可以得到如图3所示的针对04001180301这个订单的生产IOT模型300。
图3所示的生产IOT模型300中包括订单号、开始时间、结束时间、工艺编号以及它们之间的关系。
下面的表2是一个产品设计规格表的示例。
Figure PCTCN2019108241-appb-000002
表2
基于该设计规格表,可以得到如图4所示的一个产品IOT模型400中的各个参数。通过工艺属性C03可以将图4的IOT模型和图3所示的IOT模型相关联。
其中,对象401指明单元号为V101971。工艺参数402包括四个加工步骤4021、4022、4023、4024。每个工艺步骤分别包括加工时间4021-1、4022-1、4023-1、4024-1和旋转速度4021-2、4022-2、4023-2、4024-2,其中时间为2分钟。图4中的IOT模型还示出了C03的下一个工艺403为C07,前一个工艺404为C14,在图4中省略了工艺C07和C14所包括的一些属性。图4中的IOT模型还包括工具405,工具405可以包括属性机床4051,机床4051的编号为X6140。
图3和图4的IOT模型中,主要示出了在本示例中关注的一些重要信息,而省略了一部分信息。
本领域技术人员可以理解,图3和图4所示的IOT模型仅仅是为了举例说明,并不对本发明的保护范围有任何限制。
在一个示例中,还可以从工厂的数据采集自动化控制系统得到产品IOT模型中的各个参数。此外,也可以从产品说明书获得各个参数的推荐值。
基于以上所得到的IOT模型,针对订单04001180301中的单元V101971,可以确定机床x6140的生产过程如下:
1.在工艺C03中,机床进行了4个加工步骤
2.每个状态分别持续2分钟
如果在X6140机床中存在相同的工艺,则可以比较两个订单的下一个工艺,直到找到两个订单中的不同工艺进行比较。
此外,通过对由机床上设置的振动传感器监测到的数据进行学习可以确定基于振动数据表示的加工步骤的数据模型,图5是振动数据模型500的一个示意图,从图5所示的振动数据模型可以确定以下生产过程:
1.在C03中机床X6140具有4个步骤S1、S2、S3和S4。
2.每个状态分别持续2分钟。
接下来,可以对生产IOT模型所示出的生产状态以及产品IOT模型所示出的产品的生产工艺信息与基于数据学习得到的数据模型进行比较。
具体地,首先在产品IOT模型中搜索是否存在与基于振动数据的数据 模型中的加工步骤的数据同时改变、具有相同的周期或者相同的幅值的变量,如果存在这样的变量,则可以根据产品物联网模型确定当前设备加工的产品和订单号。
如果在订单04001180301的产品IOT模型中没有找到与该数据模型有直接联系的变量,则可以与基于其他传感器采集的数据所获得的数据模型进行匹配,直到对所有基于不同传感器数据所获得的数据模型都进行匹配。例如电流传感器采集的电流数据、温度传感器采集的温度数据等。
如果没有找到匹配的变量,则可以反馈不存在必要的数据。
图6是IOT模型的工艺过程与数据模型的步骤匹配结果600的一个示意图。通过对IOT模型和数据模型进行匹配,可以确定V101971的工艺C03的四个的工艺过程P1、P2、P3和P4与数据模型的四个加工步骤S1、S2、S3和S4匹配,从而根据产品IOT模型可以确定目前在C03的机床上正在进行的订单是0400110301。
在某些情况下,可能由于每个过程具有不同的时间间隔,对振动数据进行分析得到了如图7所示的错误的数据模型700,可以看到,图7中的振动数据模型包括三个步骤Sa、Sb和Sc。
在这种情况下,可以手动将结果修改为四个步骤,然后反馈给数据分析引擎来优化学习过程中所采用的规则和参数。例如,可以将时间间隔从秒级减小到微秒级。
X6140的振动传感器的数据与订单号0400110301中的V101971的C03工艺匹配。当振动传感器的数据与生产工艺匹配时,可以确定在C03机床上正在进行的订单是0400110301。
根据本公开的监控生产订单状态的方法,可以将工厂生产中的原始数据与生产过程进行匹配,来确定工厂的生产状态,例如订单的状态、设备的状态等。减少了对数据进行标记的成本,使得生产更加高效,并且可以帮助管理者了解工厂的生产状态,辅助进行生产排程。
如上参照图1到图7,对根据本公开的实施例的监控生产订单状态的装置和方法的实施例进行了描述。以上所述的监控生产订单状态的装置可以 采用硬件实现,也可以采用软件或者硬件和软件的组合来实现。
图8示出了根据本公开的实施例的监控生产订单状态的电子设备800的方框图。根据一个实施例,电子设备800可以包括至少一个处理器802,处理器802执行在计算机可读存储介质(即,存储器1004)中存储或编码的至少一个计算机可读指令(即,上述以软件形式实现的元素)。
