Description

用于程序文件编写和运行处理的方法及装置、系统 技术领域
本公开通常涉及自动化系统领域,更具体地,涉及用于程序文件编写和运行处理的方法及装置以及用于程序文件处理的系统。
背景技术
自动化系统提供商(比如,西门子、ABB和施耐德等)通常将编程工具(例如,编程软件STEP 7)和程序运行器(例如,可编程逻辑控制器(Programmable Logic Controller,PLC))一起提供给客户。通常而言,编程工具不能与来自不同提供商的程序运行器一起使用。这意味着,尽管来自不同提供商的程序运行器之间可以经由开源协议来进行通信,工程人员仍然需要在工程站中配置多种不同的编程工具(Engineering Tool)为来自不同提供商的程序运行器编写程序代码。
由此,在现有技术条件下,为了满足能够针对各种程序运行器(Runtime)实现程序代码编写,需要在工程站中配置多种不同的编程工具,然而有些来自不同提供商的编程工具并不能安装在同一台计算机上,从而使得难以对工程站进行配置。
另外,由于针对不同程序运行器的程序分布在工程站中的不同编程工具中,并且不同的编程工具使用彼此不兼容的文件格式,从而造成工程技术人员在进行程序编写时,需要了解所有程序的全局信息(比如,整体结构和逻辑),并且分别在不同的编程工具上进行程序编写。
此外,由于工程技术人员所编写的程序代码分布在不同的编程工具中,使得在进行程序调试时,需要在不同的编程工具之间频繁切换,从而为工程技术人员的工作带来许多不便。
而且,在现有技术中,当出于某些原因(例如,性能,可靠性,部署等),工程技术人员可能希望将程序从一个程序运行器迁移到另一程序运行器,或者使用新的程序运行器进行替换时,如果两个程序运行器来自不同 的提供商,则由于不能将程序从一种编程工具转换为另一种编程工具,工程技术人员需要重新编写程序。
另外,在现有技术中,一旦发生编程工具升级而对应的程序运行器未升级,则会发生编程工具的版本与程序运行器的版本不兼容的问题。
鉴于此,IEC发布了一系列标准,如IEC-61131-3和IEC-61499,以标准化不同PLC的编程语言,并将TC6XML标准定义为不同程序运行器提供商的通用文件格式。基于此,IEC希望所有提供商的编程工具都支持所有IEC61131编程语言,并使用TC6作为通用文件交换格式。
但是,尽管许多程序运行器提供商声称它们支持IEC61131,但它们的实现之间仍然存在一些差异。其原因在于,每个提供商在自己的实现方式中都具有自己的专有技术,他们不希望这部分技术能够在其他提供商所提供的程序运行器中运行。
为了对程序运行器提供商施加更多压力以遵循标准编程语言和文件格式,开源社区和一些公司提供严格遵循IEC标准的开源或免费解决方案(包括工程工具和运行时)。例如,Beremiz/CodeSys是IEC61131的开源/免费解决方案;4DIAC是IEC61499的开源解决方案。越来越多的用户(特别是对成本敏感的用户)现在利用这些免费工具开发他们的控制系统。虽然这些标准解决方案可以更容易地相互交换程序,但是安装,部署和调试对于工程技术人员来说仍然是一项繁重的工作。
对于对开源/免费解决方案没有信心的重要应用程序的用户,他们通常使用/编写特殊的程序转换器来在不同的程序运行器之间进行程序转换。这些类型的程序转换通常首先对一个提供商所提供的程序运行器中的程序进行解析并将其匹配到某个模式,然后将此模式编码为另一个提供商的程序格式。这是与不同程序运行器提供商合作的唯一可行解决方案。但是,经过上述转换后的程序通常与原有程序不完全相同,由此,为了保持与原有程序相同,工程技术人员需要付出很大的努力来进行代码修改。

图1示出了根据本公开的实施例的用于程序文件处理的系统(下文中称为程序文件处理系统10)的方框示意图。
如图1所示,程序文件处理系统10包括至少一个程序文件编写处理装置110、至少一个云端处理装置120和至少一个程序文件运行处理装置130。此外,可选地,程序文件处理系统10还可以包括至少一个程序文件监控/调试装置140。另外,在图1中,还示出了至少一个编程器20和至少一个程序运行器30。
至少一个程序文件编写处理装置110从至少一个编程器20获取已经编写好的程序文件。所述程序文件例如可以是利用各种提供商所提供的编程器,按照该提供商所规定的程序文件格式编写好的程序文件。例如,所述程序文件可以是自动控制系统的程序文件。这里,各个提供商所规定的程序文件格式相同或者不同。在本公开中,所述程序文件可以是利用线上系统或线下系统编写的,优选地,利用线下系统编写。
在本公开中,从至少一个编程器20获取程序文件可以是由该编程器主动提交给至少一个程序文件编写处理装置110,也可以是响应于至少一个程序文件编写处理装置110的请求而发送给至少一个程序文件编写处理装置110。另外,程序文件可以是实时获取的,也可以是预先获取并存储的。
在获取到程序文件后,至少一个程序文件编写处理装置110从该程序文件中抽取出程序节点描述模型,所述程序节点描述模型用于描述该程序文件中的各个节点之间的引用关系。所述程序节点描述模型可以采用适用于描述程序文件中的节点之间的引用关系的能力的描述语言来进行描述。例如,所述描述语言可以包括下述描述语言中的一种:OPC-UA地址空间格式的描述语言;JSON格式的描述语言;和XML格式的描述语言。
图2示出了根据本公开的实施例的程序文件编写处理装置110的方框 示意图。如图2所示,程序文件编写处理装置110包括程序文件类型确定单元111、选择单元113和至少一个程序描述抽象单元115。
在从编程器20获取程序文件后,编程工具类型确定单元111基于所获取的程序文件的格式,确定该程序文件的编程工具类型。这里,程序文件的编程工具类型例如可以包括连续功能图(Continuous Function Chart,CFC)编程器、Model.sys编程器、LabVIEW编程器、C++编程器、Python编程器等。然后,选择单元113从至少一个程序描述抽象单元115中选择与所确定的编程工具类型匹配的程序描述抽象单元。例如,在本公开的一个示例中,选择单元113可以根据预先配置的编程工具类型-程序描述抽象单元对应表来选择与所确定的编程工具类型匹配的程序描述抽象单元。在本公开的其他示例中,选择单元113可以根据本领域中的其他合适方式来选择与所确定的编程工具类型匹配的程序描述抽象单元。然后,使用所选择的程序描述抽象单元115来从该程序文件中抽取出程序节点描述模型。
在本公开中,每个程序描述抽象单元对应一种程序文件格式,用于从对应格式的程序文件中抽取出程序节点描述模型。例如,程序描述抽象单元可以是开放型跨语言接口,例如,其可以是用于过程控制的OPC-UA客户端的接口/界面。
在本公开中,程序文件编写处理装置110可以位于云端服务器中,也可以位于本地终端设备中。比如,程序文件编写处理装置110可以是云端服务器或本地终端设备中的一个硬件模块或软件模块,例如,程序文件编写处理装置可以是位于本地终端设备上的第一客户端中的一个软件模块。该第一客户端可以是基于网页的客户端,用户可以利用浏览器来浏览或访问该客户端以进行相应的操作。
在程序文件编写处理装置110位于本地终端设备中时,程序文件编写处理装置110还可以包括发送单元117,用于将所抽取出的程序节点描述模型发送给至少一个云端处理装置120,以供云端处理装置120分发给至少一个程序运行器。例如,发送单元117可以采用有线或无线的方式来将所抽取出的程序节点描述模型发送给云端处理装置120,比如,采用HTTP/GET协议来将所抽取出的程序节点描述模型发送给云端处理装置120。云端处理装置120可以是指位于云端的任何存储装置,例如,位于云端服务器中的 任何存储装置。在本公开中,程序运行器可以是PLC。
图3示出了根据本公开的实施例的用于程序文件编写处理的方法的流程图。图3中示出的方法由位于本地终端设备的程序文件编写处理装置执行。
如图3所示,在S310,至少一个程序文件编写处理装置110从至少一个编程器20接收程序文件。接着,在S320,基于所接收的程序文件的格式,确定该程序文件的编程工具类型。S320的操作与上面参照图2描述的编程工具类型确定单元111的操作相同。
然后,在S330,从至少一个程序描述抽象方式中选择与所确定的编程工具类型匹配的程序描述抽象方式,所述至少一个程序描述抽象方式中的每个程序描述抽象方式对应一种程序文件格式,并且具有从对应格式的程序文件中抽取出程序节点描述模型的能力。S330的操作与上面参照图2描述的选择单元113的操作相同。
在选择出匹配的程序描述方式后,在S340,利用所选择的程序描述抽象方式来从程序文件中抽取出程序节点描述模型。这里,程序描述抽象方式对应于图2中描述的程序描述抽象单元。然后,在S350,将所抽取出的程序节点描述模型发送给至少一个云端处理装置120。云端处理装置120可以是指位于云端的任何存储装置,例如,位于云端服务器中的任何存储装置。S350的操作与上面参照图2描述的发送单元117的操作相同。
在本公开的另一示例中,程序文件编写处理装置110也可以是在云端服务器中实现,在这种情况,程序文件编写处理装置110不包括发送单元117,相应地,用于程序文件编写处理的方法也不包括S350的操作。
在获取程序文件的程序节点描述模型后,至少一个云端服务器中的至少一个云端处理装置120存储所获取的程序节点描述模型,并且在程序文件运行处理装置130需要执行程序文件运行处理时,响应于程序文件运行处理装置130的请求,将所存储的程序节点描述模型发送给程序文件运行处理装置130。然后,程序文件运行处理装置130对所接收的程序节点描述模型执行转换处理,以基于程序节点描述模型中的各个节点之间的引用关系,转换出程序运行器30可执行的程序文件。
图4示出了根据本公开的实施例的程序文件运行处理装置130的方框 示意图。
如图4所示,程序文件运行处理装置130包括描述模型获取单元131。描述模型获取单元131用于从(例如,至少一个云端服务器中的)至少一个云端处理装置120获取至少一个程序节点描述模型。如上所述,所述程序节点描述模型用于描述程序文件中的各个节点之间的引用关系。
程序文件运行处理装置130还包括与运行程序文件的程序运行器匹配程序文件转换单元133。程序文件转换单元133用于基于所获取的至少一个程序节点描述模型中的各个节点之间的引用关系,将所获取的至少一个程序节点描述模型转换为所述程序运行器可执行的程序文件。在本文中,“转换”过程是指根据至少一个程序节点描述模型中包含的节点以及各个节点之间的引用关系,按照对应程序运行器可执行的程序文件所要求的格式,将至少一个程序节点描述模型转换为对应的可运行程序代码。在本公开的一个示例中,程序文件运行处理装置130可以仅仅包括一个与运行程序文件的程序运行器匹配的程序文件转换单元133。在这种情况下,该程序文件运行处理装置130仅仅对应一个程序运行器。在本公开的其他示例中,程序文件运行处理装置130可以包括多个程序文件转换单元133,每个程序文件转换单元133对应一种程序运行器。在这种情况下,该程序文件运行处理装置130可以对应于多个程序运行器。相应地,程序文件运行处理装置13可以包括程序文件转换单元选择器,用于基于运行程序文件的程序运行器来确定用于程序文件转换的程序文件转换单元。
可选地,程序文件运行处理装置130还可以包括加载单元135。加载单元135用于将所述转换后的程序文件加载到程序运行器的处理内核,以由处理内核来运行该程序文件,从而得到程序文件的运行数据。
图5示出了根据本公开的实施例的用于程序文件运行处理的方法的流程图。
如图5所示,首先,在S510,在程序运行器30需要运行程序文件时,程序运行器30向程序文件运行处理装置130发送程序文件获取请求。在接收到程序文件获取请求后,在S520,程序文件运行处理装置130向至少一个云端处理装置120发送程序文件描述模型获取请求。例如,在OPC-UA环境下,由于OPC-UA的地址空间是共享的,多个云端处理装置(即,多 个云端服务器)维护的是同一个地址空间,所以程序文件运行处理装置130可以向任何一个云端处理装置120发送程序文件描述模型获取请求。在接收到程序文件描述模型获取请求后,在S530,至少一个云端处理装置120向程序文件运行处理装置130返回至少一个程序节点描述模型。所述程序节点描述模型用于描述程序文件中的各个节点之间的引用关系。
然后,在S540,在程序文件运行处理装置130处,经由与运行所述程序文件的程序运行器匹配的程序文件转换单元,基于所获取的至少一个程序节点描述模型中的各个节点之间的引用关系,将所获取的至少一个程序节点描述模型转换为程序运行器可执行的程序文件。然后,在S550,将所转换出的可执行程序文件加载到程序运行器30,例如,加载到程序运行器30的处理内核,以由程序运行器30来执行,由此生成程序运行数据。
此外,程序文件运行处理系统10还可以包括至少一个监控/调试装置140。至少一个监控/调试装置140用于从至少一个云端处理装置120接收所述实时运行数据和历史运行数据,并且基于所接收的实时运行数据和历史运行数据来进行监控和/或调试。相应地,至少一个云端处理装置120还用于:存储所述至少一个程序运行器30执行完所加载的程序文件后得到的实时运行数据以及历史运行数据。
图6示出了根据本公开的实施例的用于程序文件监控及调试的方法的流程图。
如图6所示,在S610,在程序运行器30运行完程序文件后,将所得到的实时运行数据和历史运行数据经由无线或有线的方式发送给至少一个云端处理装置120。例如,可以经由HTTP来将实时运行数据发送给至少一个云端处理装置120以存储到实时运行数据库中,以及经由FTP来将历史运行数据发送给至少一个云端处理装置120以存储到历史运行数据库中。要说明的是,程序运行器30也可以采用其他合适的协议来将实时运行数据和历史运行数据发送给至少一个云端处理装置120。然后,在S620,至少一个云端处理装置120将实时运行数据和历史运行数据与程序节点描述模型中的对应节点相关联地存储。
在如上针对运行数据进行存储后,如果在S630,至少一个云端处理装置从至少一个程序文件监控/调试装置140接收程序文件运行监控及调试请 求,则在S640,至少一个云端处理装置120将对应的实时运行数据和历史运行数据发送给至少一个程序文件监控/调试装置140。然后,在S650,至少一个程序文件监控/调试装置140基于所接收的实时运行数据和历史运行数据进行监控和调试。
图7示出了根据本公开的实施例的程序文件处理系统10在OPC-UA环境下的操作过程的示意图。
如图7所示,程序文件处理系统10包括程序文件编写处理装置110、云端处理装置120-1、120-2、程序文件运行处理装置130-1、130-2以及程序程序文件监控/调试装置140。这里要说明的是,图7中示出的程序文件编写处理装置、云端处理装置、程序文件运行处理装置以及程序程序文件监控/调试装置的数量仅仅是示例,在其他示例中,程序文件编写处理装置、云端处理装置、程序文件运行处理装置以及程序程序文件监控/调试装置的数量可以是其他合适的数量。
参见图7,在程序编写阶段,在编程器20已经编写好程序文件后,发送给程序文件编写处理装置110。然后,编程工具类型确定单元111基于所获取的程序文件的格式,确定该程序文件的编程工具类型,例如图7中的文件是利用CFC编程器编写的程序,则该程序文件的编程工具类型是CFC编程器。然后,选择单元113从至少一个程序描述抽象单元115中选择与CFC编程器匹配的程序描述抽象单元115-2。这里,程序描述抽象单元115是OPC-UA客户端119的接口/界面。然后,使用程序描述抽象单元115-2来从该程序文件中抽取出程序节点描述模型。在抽取出程序节点描述模型后,由程序文件编写处理装置110上的OPC-UA客户端119,经由HTTP/GET协议来将所抽取出的程序节点描述模型发送给云端处理装置120来进行存储,以供程序运行处理装置130后续下载使用。
在程序运行阶段,如果程序运行器30(比如,DCRT Runtime 30-1,ForteRuntime 30-2)需要运行程序文件,则程序运行器30向程序文件运行处理装置130发送程序文件获取请求。在接收到程序文件获取请求后,程序文件运行处理装置130经由OPC-UA客户端119向至少一个云端处理装置发送程序文件描述模型获取请求。在OPC-UA环境下,由于OPC-UA的地址空间是共享的,多个云端处理装置(即,多个云端服务器)维护的是同一 个地址空间,所以程序文件运行处理装置130可以向任何一个云端处理装置发送程序文件描述模型获取请求。在接收到程序文件描述模型获取请求后,至少一个云端处理装置120向程序文件运行处理装置130返回至少一个程序节点描述模型。然后,经由与运行所述程序文件的程序运行器30匹配的程序文件转换单元133-1/133-2,基于所获取的至少一个程序节点描述模型中的各个节点之间的引用关系,将所获取的至少一个程序节点描述模型转换为程序运行器可执行的程序文件50-1、50-2。接着,将所转换出的可执行程序文件50-1/50-2加载到程序运行器30,例如,加载到程序运行器30的处理内核,以由程序运行器30来执行,由此生成程序运行数据。
在程序监控/调试阶段,至少一个监控/调试装置140经由OPC-UA客户端119向至少一个云端处理装置120发送数据获取请求。在接收到数据获取请求后,至少一个云端处理装置120将所存储的实时运行数据和历史运行数据发送给至少一个监控/调试装置140。至少一个监控/调试装置140的处理器内核60中的数据接收器70接收到实时运行数据和历史运行数据后,利用视图模型80来转换为相应的视图90,以提供给用户进行监控和/或调试。
