根据Gartner的定义,运营技术(Operational Technology,OT)集合了硬件和软件,通过直接地监视和/或控制物理设备(称为OT设备),检测或触发企业中过程的变化或发生的事件。OT利用计算机监视或改变诸如工业控制系统(Industrial Control System,ICS)的物理状态。其中,工业控制系统是基于计算机实现的设施、系统和设备,用于远程监视和/或控制关键的工业过程,实现物理功能。“OT”这个词的叫法用于将工业控制系统和传统的信息技术(Information Technology,IT)系统在技术实现和功能上加以区分。
IT域、OT域融合在企业数字化转型过程中变得日趋重要。其中,一个亟待解决的问题是企业如何采用易于理解、而不是IT域编程的方式来收集OT域的数据并控制OT域过程。
目前,市场上存在诸多IT低代码开发工具或平台。其中,部分工具针对物联网的使用场景,面向有经验的IT工程师,而OT工程师和初级IT工程师则难以理解其范式。而部分工具更适用于IT域低代码开发的使用场景,不能很好地适用于OT域。

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。
本发明提出了一种采用通用信息模型来实现软件平台和OT域的工作单元之间的通信的信息处理方法,收集OT域的数据并控制OT域过程,所有工作流的元素都采用通用信息模型来描述,以有助于实现IT域和OT域的融合。
下面结合附图对本申请实施例进行详细说明。
在本文中,提出了“工作单元(Workcell)”的概念,工作单元可以是能够实现一个相对完整和独立的控制流程和操作的系统或设备组合。本实施例中,以工作单元为基本单位进行工作流创建,更符合工业控制的特点,可提高开发的集成度,并降低开发的复杂度。例如,以工业技术领域为例,工作单元可以根据实际的工业场景定义,比如:可以定义一个工序对应一个工作单元,或者也可以定义工序中的一个工站为一个工作单元,又或者也可以定义工站中的一个工位对应一个工作单元等,不同的工作单元的工艺流程不同。
在本发明的一个实施例中,工作流可以为OT域工作流;工作单元可以为OT域内的工作单元;所述设备可以为OT设备。这里,OT设备可包括但不限于:物联网(Internet of Things,IoT)设备、可编程逻辑控制器(Programmable Logic Controller,PLC)、机器人(Robotics)、人工过程(Manual Process)、工控机(Industrial Personal Computer,IPC)等。
图1示出了根据本申请实施例的信息处理方法在工业自动化领域的一个应用场景。用户在软件平台10上操作,生成一个OT域工作流,该OT域工作流定义了图1右侧所示的作为一个工作单元20的生产线要执行的操作。将生成的工作流部署到工作单元20的主控制器的运行时30,以便由运行时30控制完成工作单元20的生产线操作。用户可在图1中的图形用户界面GUI中通过拖拽编辑包括功能块节点在内的各个节点实现对OT域工作流的编辑,比 如:从数据库&服务器处获取所需的数据(比如:工件加工参数),控制整个工作单元的运行。这里的工作单元为一个生产线,生产线上可以包括机器、传送带、机械臂、人、PLC、AGB等。
图2为示出了根据本发明第一方面的实施例在软件平台侧执行的信息处理方法200的示例性过程的流程图。
首先,在步骤S202中,软件平台接收用户输入的指令。
在一个具体示例中,用户输入的指令可以是用户根据需要在软件平台的图形用户界面上拖拽编辑功能块,来实现对OT域工作流的编辑。
接着,在步骤S204中,基于所述指令生成采用通用信息模型描述的OT域中的一个工作流。OT域工作流用于定义OT域中一个工作单元要执行的操作,其中,工作单元的主控制器连接工作单元中的各OT设备,可以控制各OT设备按照OT域工作流的定义完成工作单元要执行的操作。
在本发明的信息处理方法中,所生成的工作流中的所有元素都采用通用信息模型进行描述。
在步骤S206中,将所述通用信息模型描述的所述工作流部署到所述工作单元的主控制器的运行时中。
上面是在软件平台侧执行的信息处理方法,在软件平台侧,基于用户输入的指令生成了采用通用信息模型描述的工作流,并将这这样的工作部署到工作单元的主控制器的运行时中。
接下来,将说明根据本发明实施例第二方面在工作单元侧执行的信息处理方法。图3为示出了根据本发明实施例第二方面的信息处理方法300的示例性过程的流程图。
首先,在步骤S302中,OT域中的一个工作单元的主控制器接收采用通用信息模型描述的OT域中的一个工作流。
接着,在步骤S304中,所述主控制器的运行时基于所述通用信息模型解析所述工作流,来控制所述工作单元中的OT设备按照所述工作流执行相应的操作。
在本发明的信息处理方法中,采用通用信息模型来描述在软件平台和工作单元之间交换的所有元素。通过采用通用信息模型的元信息,使得工作流中的每一个元素都是标准化并且可索引,最终形成一个生态系统。
下面参照图4说明在本发明的实施例中采用的一种通用信息模型400的格式的具体示例。
根据本发明实施例所采用的通用信息模型可以采用标记语言例如XML(可扩展标记语 言)描述,并且可被XML Schema(XSD)原型校验,以验证通用信息模型实例的XML格式是正确的,因此标记格式(schema)是通用信息模型的核心。本发明的通用信息模型是针对IT域和OT域的、领域特定的通用信息模型。
如图4所示,通用信息模型400包括:信息模型基础402、信息模型结构规范404和信息模型实例库406三个部分。
其中,信息模型基础402中描述通用信息模型的数据类型的定义和所述信息模型结构规范中的元数据的元定义。在信息模型基础中包括元数据本身的元定义(可以称之为“元之元”)。信息模型基础是用于校验其它通用信息模型格式的基础格式。
此外,信息模型基础402还可以包括命名空间、基本数据类型、元数据类型等信息。
信息模型结构规范404中描述对于信息模型实例库中的每一个信息模型实例的结构定义。所有的通用信息模型格式都符合信息模型结构规范中所定义的结构,并且按照这样的结构进行校验。
图5示出了信息模型结构规范404的格式的一个具体示例。
优选地,信息模型结构规范404可以包括四个部分:元数据、用户界面信息UI、数据和资源。
其中元数据是强制必须有的。元数据是通用信息模型的可索引部分,用于索引出该通用信息模型实例在整个系统中的位置。元数据可以包括:全局统一命名空间、UUID、实例的URI、通用信息模型的元信息和证书信息等基本信息信息。
用户界面信息用于描述所述软件平台的用户界面上可以看到的所有信息,具体可以包括数据的显示名称(例如电压、电流、机器人、PLC等)、用户界面图形数据等。
数据(Data)用于描述工作流中的数据的信息,可以包括数据标签名称、数据属性以及数据结构等。
数据标签名称和数据属性用于索引到数据中的具体某一个数据结构。
数据结构优选采用行为树(behavior tree)逻辑的树(tree)形式,此外,数据结构还可以采用有向图(directed graph)或者其它形式。
在本发明的通用信息模型中,数据本身与用户界面信息是无关的,例如,数据的显示名称可以是多语言、不同颜色的,将这些信息放在用户界面信息中,实现了数据和用户界面信息的解耦。在元数据部分中,包括一个全局唯一命名空间,可以用于唯一识别采用通用信息模型描述的元素在整个系统中的位置。
资源用于描述所述工作流中的所有静态资源,通常采用二进制形式表示。静态资源不是描述数据本身,而是一些辅助信息,例如可以包括图片、视频、音乐、数据文件(例如一个 pdf文件)和源代码等。对于静态资源,不用解析其具体内容,而是附在信息模型后面。
以上四个部分组成了通用信息模型的信息模型结构规范的一个具体示例。可以理解,本领域技术人员可以根据需要修改这个四个部分中的具体内容,还可以根据需要增加其它部分或减少某个部分,而不限于这里具体描述的内容。
将OT域中的所有元素都采用通用信息模型来描述为信息模型实例,这些信息模型实例就构成了信息模型实例库406。
优选地,信息模型实例406可以包括采用通用信息模型描述的OT域中的一个工作流、一个功能块或者资源描述的实例。所有的信息模型实例都由信息模型格式校验。
利用以上所定义的通用信息模型,步骤S204具体可以包括:基于所述用户在所述软件平台的图形用户界面上编辑的OT域工作流,用所述元数据描述与所述数据流有关的信息的索引;描述所述软件平台的用户界面中的信息;描述所述工作流中的数据,所述数据包括:数据标签名称、数据属性、以及由行为树或者有向图表示的数据结构中的至少一项;以及描述所述工作流的静态资源,包括:图标、图像、数据文件和源代码中的至少一项。
根据本发明的信息处理方法,IT域和OT域所有的领域专有技术(domain knowledge)以及有关的元素(例如工作流、功能块、资源描述等)都可以描述为通用信息模型实例,生成领域专有技术和定制用例的实例,从而形成一个IT域和OT域的通用信息模型生态系统。
