Description

数据交互模型更新方法、装置、电子设备和存储介质 技术领域
本申请实施例涉及工业自动化技术领域,尤其涉及一种数据交互模型的更新方法、装置、电子设备和存储介质。
背景技术
在自动化控制系统中,与现场设备的通信至关重要。因此需要为工业以及其它对数据通信的安全性、可靠性、互操作能力有更高要求的领域制定的互操作标准。另一方面,由于各平台是独立的,同一系统间的各平台的信息不能以统一方式被访问,因此需要为不同厂家的设备提供无差异的数据描述和操作接口。
目前,为了解决上述问题,一种常见的方法是通过OPC UA通信技术作为关键技术实现工业设备互联互通,能够提供一致、完整的地址空间和服务模型,解决了过去同一系统间的各平台的信息不能以统一方式被访问的问题。同时OPC UA提供了快速建模方法,实现数据语义表达,简化数据互联互通、降低数据融合难度。
然而,部分OPC UA服务器不支持按照OPC UA的规范创建模型更新事件,导致OPC UA客户端不能够确定对连接在OPC UA服务器上的对象节点所进行的更新的具体信息。导致了每次OPC UA服务器维护工程师对OPC UA对象节点进行更新时,需要OPC UA服务器维护工程师手动对各数据交互对象的配置信息进行更新,进而导致对OPC UA服务器进行维护的效率较低。

具体实施方式
为了使本领域的人员更好地理解本申请实施例中的技术方案,下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅是本申请实施例一部分实施例,而不是全部的实施例。基于本申请实施例中的实施例,本领域普通技术人员所获得的所有其他实施例,都应当属于本申请实施例保护的范围。
数据交互模型更新方法
图1是本申请一个实施例的数据交互模型更新方法的流程图,如图1所示,该数据交互模型更新方法100包括如下步骤:
步骤101、接收对象节点更新信息。
首先接收对象节点更新信息,该对象节点更新信息可以是由OPC UA服务器维护工程师通过用户界面发送的。对象节点更新信息用于指示对连接在OPC UA服务器上的对象节点进行的更新。
例如,接收到的对象节点更新信息为删除对象节点1,此时的对象节点更新信息用于指示对连接在OPC UA服务器上的对象节点1进行删除操作。
需要说明的是,对象节点更新信息可以包括指示新增连接至OPC UA服务器的对象节点/指示删除连接至OPC UA服务器的对象节点/指示对连接至所述OPC UA服务器的对象节点进 行修改等信息,在此处不作限定。
步骤102、根据对象节点更新信息,向OPC UA服务器发送模型更新指令。
在接收到对象节点更新信息后,向OPC UA服务器发送模型更新指令。模型更新指令用于指示OPC UA服务器对数据交互模型进行更新。
步骤103、根据对象节点更新信息,生成配置更新指令。
在接收到对象节点更新信息后,生成配置更新指令。配置更新指令用于指示数据交互对象对配置信息进行更新,配置信息包括被更新的对象节点的属性信息。
步骤104、将配置更新指令发送给至少一个数据交互对象。
在生成配置更新指令后,将配置更新指令发送给至少一个数据交互对象。每个数据交互对象分别根据对应的配置更新指令进行更新后,各数据交互对象能够分别与更新后的数据交互模型中对应的部分达成数据同步。
在本申请实施例中,通过接收对象节点更新信息,能够确定对连接在OPC UA服务器上的对象节点所进行的更新,进而根据对象节点更新信息,向OPC UA服务器发送模型更新指令,指示OPC UA服务器对数据交互模型进行更新,使数据交互模型能够与更新后的对象节点进行数据交互。同时根据对象节点更新信息,生成并向至少一个数据交互对象发送配置更新指令,使数据交互对象确定被更新的对象节点信息以及更新操作信息,进而根据配置更新指令对配置信息进行更新,使配置信息与更新后的对象节点相匹配,无需手动对各数据交互对象的配置信息进行更新,提高对OPC UA服务器进行维护的效率。
在一种可能实现的方式中,将配置更新指令发送给至少一个数据交互对象时,可以根据对象节点更新信息所指示更新对应的至少一个对象节点,确定订阅配置更新指令的目标数据交互对象,进而将配置更新指令发送给目标数据交互对象。
在将配置更新指令发送给至少一个数据交互对象的过程中,由于并非所有数据交互对象都需要接收配置更新指令,因此首先需要根据对象节点更新信息所指示更新对应的至少一个对象节点,确定订阅配置更新指令的目标数据交互对象。在确定订阅配置更新指令的目标数据交互对象后,将配置更新指令发送给目标数据交互对象,以使目标数据交互对象能够根据配置更新指令自动对配置信息进行更新。
在本申请实施例中,通过根据对象节点更新信息所指示更新对应的至少一个对象节点,确定了需要进行更新的对象节点。由于不同的目标数据交互对象订阅了不同部分的对象节点更新信息,因此通过需要进行更新的对象节点确定需要下发配置更新指令的目标数据交互对象,进而避免了在下发配置更新指令时,对所有数据交互对象进行下发,造成了部分数据交互对象接收到了无效的配置更新指令,产生了垃圾数据,提高了数据交互对象对配置信息进 行更新的安全性。
在一种可能实现的方式中,在接收对象节点更新信息之外,可以向OPC UA服务器发送模型请求指令,并接收OPC UA服务器响应于模型请求指令发送的模型信息,然后通过用户界面对模型信息进行展示。
在进行数据交互模型更新中,还可以向OPC UA服务器发送模型请求指令,模型请求指令用于请求读取数据交互模型的模型信息。
在OPC UA服务器响应于模型请求指令后,会发送模型信息。接收该模型信息后,通过用户界面对模型信息进行展示。
例如,用户界面可以是通过面向对象的计算机编程语言进行编译获得的应用界面,在应用界面中展示模型信息。
在本申请实施例中,通过向OPC UA服务器发送模型请求指令,进而获取OPC UA服务器发送的模型信息,再通过用户界面对该模型信息进行展示,能够方便OPC UA服务器维护工程师通过用户界面进行下发对象节点更新信息等操作,提高了工作人员的使用体验。
在一种可能实现的方式中,根据对象节点更新信息向OPC UA服务器发送模型更新指令时,如果若对象节点更新信息指示新增连接至OPC UA服务器的对象节点,则可以生成模型新增指令,将模型新增指令作为模型更新指令发送给OPC UA服务器。
由于对象节点更新信息可以包括指示新增连接至OPC UA服务器的对象节点/指示删除连接至OPC UA服务器的对象节点/指示对连接至所述OPC UA服务器的对象节点进行修改等信息,因此针对对象节点更新信息指示新增连接至OPC UA服务器的对象节点的情况,对应生成模型新增指令。此时的模型更新指令即为模型新增指令,模型新增指令用于指示OPC UA服务器在数据交互模型中新增第一数据交互服务,第一数据交互服务用于新增的对象节点与数据交互对象进行数据交互。
在本申请实施例中,针对对象节点更新信息包括信息的新增情况,相应生成模型新增指令,能够直接指示OPC UA服务器完成需要执行的更新操作为新增操作,提高了更新效率。
在一种可能实现的方式中,根据对象节点更新信息向OPC UA服务器发送模型更新指令时,如果若对象节点更新信息指示删除连接至OPC UA服务器的对象节点,则可以生成模型删除指令,将模型删除指令作为模型更新指令发送给OPC UA服务器。
由于对象节点更新信息可以包括指示新增连接至OPC UA服务器的对象节点/指示删除连接至OPC UA服务器的对象节点/指示对连接至所述OPC UA服务器的对象节点进行修改等信息,因此针对对象节点更新信息指示删除连接至OPC UA服务器的对象节点的情况,对应生成模型删除指令。此时的模型更新指令即为模型删除指令,模型删除指令用于指示OPC UA 服务器将数据交互模型中的第二数据交互服务删除,第二数据交互服务用于被删除的对象节点与数据交互对象进行数据交互。
在本申请实施例中,针对对象节点更新信息包括信息的删除情况,相应生成模型删除指令,能够直接指示OPC UA服务器完成需要执行的更新操作为删除操作,提高了更新效率。
在一种可能实现的方式中,根据对象节点更新信息向OPC UA服务器发送模型更新指令时,如果若对象节点更新信息指示修改连接至OPC UA服务器的对象节点,则可以生成模型修改指令,将模型修改指令作为模型更新指令发送给OPC UA服务器。
由于对象节点更新信息可以包括指示新增连接至OPC UA服务器的对象节点/指示删除连接至OPC UA服务器的对象节点/指示对连接至所述OPC UA服务器的对象节点进行修改等信息,因此针对对象节点更新信息指示修改连接至OPC UA服务器的对象节点的情况,对应生成模型修改指令。此时的模型更新指令即为模型修改指令,模型修改指令用于指示OPC UA服务器将数据交互模型中的第三数据交互服务删除,并在数据交互模型中新增第四数据交互服务,第三数据交互服务用于被修改之前的对象节点与数据交互对象进行数据交互,第四数据交互服务用于修改之后的对象节点与数据交互对象进行数据交互。
在本申请实施例中,针对对象节点更新信息包括信息的修改情况,相应生成模型修改指令,能够直接指示OPC UA服务器完成需要执行的更新操作为修改操作,提高了更新效率。
在一种可能实现的方式中,在完成OPC UA服务器对数据交互模型进行更新,以及数据交互对象对配置信息进行更新后,生成模型更新日志。
在数据交互模型更新过程中,可以通过根据对象节点更新信息,生成模型更新日志的方式,对对象节点更新信息进行存储。
在接收到来自数据交互对象的日志读取请求之后,响应于来自数据交互对象的日志读取请求,将模型更新日志发送给数据交互对象。
数据交互对象可以发送日志读取请求,在接收到数据交互对象发送的日志读取请求后,响应于来自数据交互对象的日志读取请求,将模型更新日志发送给数据交互对象。
在本申请实施例中,通过根据对象节点更新信息,生成模型更新日志,对对象节点更新信息进行存储。数据交互对象可以通过发送日志读取请求获取模型更新日志,进而获得对象节点更新信息。使各数据交互对象可以随时查询对象节点更新信息,进而对配置信息进行校验,提高了数据的安全性。

图2是本申请一个实施例的数据交互模型更新装置的示意图,如图2所示,该数据交互模型更新装置200包括:接收模块201、第一发送模块202、生成模块203和第二发送模块 204。
接收模块201,用于接收对象节点更新信息,其中,对象节点更新信息用于指示对连接在OPC UA服务器上的对象节点进行的更新。
首先通过接收模块201接收对象节点更新信息,该对象节点更新信息可以是由OPC UA服务器维护工程师通过用户界面发送的。对象节点更新信息用于指示对连接在OPC UA服务器上的对象节点进行的更新。
例如,接收到的对象节点更新信息为修改对象节点2,此时的对象节点更新信息用于指示对连接在OPC UA服务器上的对象节点2进行修改操作。
需要说明的是,对象节点更新信息可以包括指示新增连接至OPC UA服务器的对象节点/指示删除连接至OPC UA服务器的对象节点/指示对连接至所述OPC UA服务器的对象节点进行修改等信息,在此处不作限定

模型修改指令子模块2023,用于当对象节点更新信息指示修改连接至OPC UA服务器301的对象节点303时,生成模型修改指令。
针对对象节点更新信息指示修改连接至OPC UA服务器301的对象节点303的情况,对应生成模型修改指令。此时的模型更新指令即为模型修改指令,模型修改指令用于指示OPC UA服务器301将数据交互模型中的第三数据交互服务删除,并在数据交互模型中新增第四数据交互服务,第三数据交互服务用于被修改之前的对象节点303与数据交互对象302进行数据交互,第四数据交互服务用于修改之后的对象节点303与数据交互对象302进行数据交互。
在本申请实施例中,通过第三生成模块205根据对象节点更新信息,生成模型更新日志,对对象节点更新信息进行存储。数据交互对象302可以通过发送日志读取请求获取模型更新日志,进而获得对象节点303更新信息。使各数据交互对象302可以随时查询对象节点303更新信息,进而对配置信息进行校验,提高了数据的安全性。针对对象节点更新信息包括信息的新增情况,模型新增指令子模块2021相应生成模型新增指令,能够直接指示OPC UA服务器301完成需要执行的更新操作为新增操作。针对对象节点更新信息包括信息的删除情况,模型删除指令子模块2022相应生成模型删除指令,能够直接指示OPC UA服务器301完成需要执行的更新操作为删除操作。针对对象节点更新信息包括信息的修改情况,模型修改指令子模块2023相应生成模型修改指令,能够直接指示OPC UA服务器301完成需要执行的更新操作为修改操作,提高了更新效率。
在一种可能实现的方式中,第二发送模块204,还用于根据对象节点更新信息所指示更新对应的至少一个对象节点303,确定订阅配置更新指令的目标数据交互对象302。
在将配置更新指令发送给至少一个数据交互对象302的过程中,由于并非所有数据交互对象302都需要接收配置更新指令,因此首先需要根据对象节点更新信息所指示更新对应的至少一个对象节点303,确定订阅配置更新指令的目标数据交互对象302。
第二发送模块204,还用于将配置更新指令发送给目标数据交互对象302。
在确定订阅配置更新指令的目标数据交互对象302后,第二发送模块204将配置更新指令发送给目标数据交互对象302,以使目标数据交互对象302能够根据配置更新指令自动对配置信息进行更新。
在本申请实施例中,第二发送模块204通过根据对象节点更新信息所指示更新对应的至少一个对象节点303,确定了需要进行更新的对象节点303。由于不同的目标数据交互对象302订阅了不同部分的对象节点更新信息,因此第二发送模块204通过需要进行更新的对象节点303确定需要下发配置更新指令的目标数据交互对象302,进而避免了在下发配置更新 指令时,对所有数据交互对象302进行下发,造成了部分数据交互对象302接收到了无效的配置更新指令,产生了垃圾数据,提高了数据交互对象302对配置信息进行更新的安全性。
在一种可能实现的方式中,数据交互模型更新系统300还包括:第四发送模块和接收模块。
第四发送模块,用于向OPC UA服务器301发送模型请求指令。
在进行数据交互模型更新中,还可以通过第四发送模块向OPC UA服务器301发送模型请求指令,模型请求指令用于请求读取数据交互模型的模型信息。
接收模块,用于接收OPC UA服务器301响应于第四发送模块发送的模型请求指令后发送的模型信息。
数据交互模型更新系统300通过用户界面对模型信息进行展示。
在OPC UA服务器301响应于第四发送模块发送的模型请求指令后,会发送模型信息。接收模块接收该模型信息后,数据交互模型更新系统300通过用户界面对模型信息进行展示。
