Description
本公开通常涉及自动化系统技术领域,更具体地,涉及现场设备的控制方法、现场设备、移动设备以及存储介质。
随着嵌入式设备实现越来越多的功能性,要求具有非常复杂的用户界面。因此,大量的嵌入式设备目前集成真彩色LCD屏幕以及触摸传感器来提供全特征的交互。
然而,这种方式不符合成本效益。LCD屏幕和触摸传感器可能非常昂贵,而如果降低这些用户界面部件的成本又可能对用户体验产生很大的不利影响。
目前通常采用以下两种方式来解决这个问题。
一、共享用户界面硬件
由于用户界面部件(例如LCD屏幕、触摸传感器)通常很昂贵,一种可能的解决方案是让许多设备共享同一个用户界面部件,特别是当用户界面不经常被访问时。例如,许多工业控制系统为操作员提供便携式HMI(人机接口)面板。操作员可以通过网络或物理连接将他们的HMI面板连接到设备上,这样就可以访问该设备提供的用户界面。然而,这样的便携式HMI面板可能仍然非常昂贵。
二、用户移动应用提供可选的用户界面
现在很多嵌入式设备使用移动应用程序进行用户互动。它要求用户安装某个移动应用(app),该应用可以连接到他们的设备进行数据交换,并在该移动应用上提供用户接口。然而,这样的移动应用程序是针对特定目标的,这意味着一个移动应用程序只针对某个特定设备设计。如果设备的固件发生变化,制造商也需要升级相应的移动应用程序。更重要的是,如果安装基础有不同版本的固件,移动应用程序也需要考虑向后兼容的问题,这使得移动应用程序的维护变得非常复杂。
发明内容
在下文中给出关于本发明的简要概述,以便提供关于本发明的某些方面的基本理解。应当理解,这个概述并不是关于本发明的穷举性概述。它并不是意图确定本发明的关键或 重要部分,也不是意图限定本发明的范围。其目的仅仅是以简化的形式给出某些概念,以此作为稍后论述的更详细描述的前序。
有鉴于此,本公开提出了一种现场设备的控制方法,采用NFC通信协议在现场设备和移动设备之间传送矢量图(现场设备->移动设备)和用户事件(移动设备->现场设备)。
根据本公开的一个方面,提供了一种现场设备的控制方法,包括:

事件生成模块,被配置为接收用户对所述图形用户界面的动作,基于所述动作生成控制事件信息;以及
发送模块,被配置为将所述控制事件信息通过NFC协议发送给现场设备。
根据本公开的另一方面,提供了计算设备,包括:至少一个处理器;以及与所述至少一个处理器耦合的一个存储器,所述存储器用于存储指令,当所述指令被所述至少一个处理器执行时,使得所述处理器执行如上所述的方法。
根据本公开的另一方面,提供了一种非暂时性机器可读存储介质,其存储有可执行指令,所述指令当被执行时使得所述机器执行如上所述的方法。
根据本公开的另一方面,提供了一种计算机程序,包括计算机可执行指令,所述计算机可执行指令在被执行时使至少一个处理器执行如上所述的方法。
根据本公开的另一方面,提供了一种计算机程序产品,所述计算机程序产品被有形地存储在计算机可读介质上并且包括计算机可执行指令,所述计算机可执行指令在被执行时使至少一个处理器执行如上所述的方法。
根据本公开的现场设备的控制方法,由于NFC通信可以在现场设备进入用户的移动设备的NFC范围内时自动建立,使得用户和现场设备的互动可以非常方便、直观。当移动设备物理上接近一个现场设备时,移动应用程序将显示现场设备的用户界面;当移动设备物理上离开现场设备时,用户界面将消失。不需要将移动应用程序与现场设备连接或配对,用户可以轻松地在不同现场设备的用户界面之间切换,甚至不需要切换应用程序。
由于是将矢量图传送到移动设备进行显示,即使在不同的移动设备上渲染,所显示的图形用户界面看起来也应该是一样的,这样确保用户界面在不同设备上的显示是相同的。此外,矢量图是可扩展的,所以可以适应不同的屏幕分辨率,保持良好的图像质量。
在本公开的方法中,移动设备可以是用户随时携带的移动电话,因此具有很好的用户体验,成本很低,现在大多数现代智能手机都已经安装了NFC芯片,可以支持NFC通信。另一方面,在现场设备上添加NFC芯片也要比LCD屏幕和触摸传感器便宜得多。

有鉴于此,本公开提出了一种针对现场设备的控制方法,这种方法利用用户的移动设备来提供用户界面,与现有技术中的方法不同的是,根据本公开的方法无需在现场设备和移动设备之间传送过程数据。
下面将结合附图来描述根据本公开的实施例的现场设备的控制方法。
图1是现场设备500和用户的移动设备600之间进行通信交互的示意图。
其中,现场设备500可以是仪器、仪表、电机等任意工业设备,移动设备600可以是手机、平板电脑、笔记本电脑等任何可以被用户持有的便携式移动设备,现场设备500和移动设备600之间通过NFC(Near Field Communication,近场通信)协议进行通信,用户通过移动设备600可以实现与现场设备500的交互控制。
图2是根据本公开实施例的现场设备的控制方法200的示例性过程的流程图。
首先,在图2的方框S202中,将现场设备的用户界面编码为可放缩矢量图(Scalable Vector Graphics,SVG),简称为矢量图,并将矢量图通过NFC协议发送给移动设备。
接着,在方框S204中,移动设备通过NFC协议接收矢量图,并基于接收到的矢量图在移动设备的屏幕上渲染图形用户界面。
这里,需要现场设备和移动设备都支持NFC通信方式,例如具有NFC天线。
上述将用户界面编码为矢量图以及基于矢量图渲染图形用户界面都可以采用现有技术中的常用方法,本发明对于所采用的具体方法不做限定,在此不再详述。
接着,在方框S206中,移动设备接收用户对渲染的图形用户界面的动作,基于动作 生成控制事件信息,并将控制事件信息通过NFC协议发送给现场设备。
在该步骤中,用户可以对移动设备上渲染的图形用户界面根据需要进行操作,再通过下面的步骤就可以实现对现场设备的控制。
最后,在方框S208中,现场设备对接收到的控制事件信息进行解析获得用户输入指令,并基于用户输入指令来对现场设备进行控制。
根据本公开的方法无需在现场设备和移动设备之间传送过程数据,而是通过标准ISO15693的NFC协议将用户界面编码的矢量图发送给移动设备。
根据本公开的现场设备的控制方法主要通过采用可扩展矢量图(SVG)技术和NFC技术来实现。可扩展矢量图提供了一种增量传送矢量图的标准方式,从而提供了在相对较低的带宽连接(如NFC)上进行图形传输的可能性。同时,最新的NFC技术已经可以支持50Kbit/s以上的数据速率,从而也可以保证通信质量。
换言之,在移动设备上的应用程序没有任何业务逻辑,而是只负责将来自现场设备的矢量图渲染到屏幕上,并且将用户事件发送回现场设备。在现场设备上生成矢量图,并且在现场设备上处理用户事件。这意味着用户界面仍然运行在现场设备中,只是在外部呈现出来。
根据本公开的现场设备的控制方法具有以下技术优势中的一项或多项。
能够提供直观的界面
由于NFC通信可以在现场设备进入用户的移动设备的NFC范围内时自动建立,使得用户和现场设备的互动可以非常方便、直观。当移动设备物理上接近一个现场设备时,移动应用程序将显示现场设备的用户界面;当移动设备物理上离开现场设备时,用户界面将消失。不需要将移动应用程序与现场设备连接或配对,用户可以轻松地在不同现场设备的用户界面之间切换,甚至不需要切换应用程序。
具有通用性和一致性
由于是将矢量图传送到移动设备进行显示,即使在不同的移动设备上渲染,所显示的图形用户界面看起来也应该是一样的,这样确保用户界面在不同设备上的显示是相同的。此外,矢量图是可扩展的,所以可以适应不同的屏幕分辨率,保持良好的图像质量。
低成本的良好用户体验
在本公开的方法中,移动设备可以是用户随时携带的移动电话,因此具有很好的用户体验,成本很低,现在大多数现代智能手机都已经安装了NFC芯片,可以支持NFC通信。 另一方面,在现场设备上添加NFC芯片也要比LCD屏幕和触摸传感器便宜得多。
作为一个具体示例,矢量图在压缩后可能只有32Kbit,在NFC可以支持50Kbit/s的数据速率的情况下,这意味着可以在1秒内通过NFC将矢量图传输到用户的屏幕上。此外,在手机和NFC芯片之间的一个连接会话中,只有矢量图的差异会被传输(SVG支持增量更新),这需要更少的带宽。
在图2所示的根据本公开实施例的现场设备的控制方法中,涉及现场设备和移动设备两个方面。对于现场设备,其执行的操作步骤如图3所示。图3为根据本公开实施例在现场设备处执行的控制方法300的示例性过程的流程图,所述方法具体包括:
首先,在S302中,将现场设备的用户界面编码为矢量图。
接着,在S304中,通过NFC协议将所述矢量图发送出去。
在S306中,通过NFC协议接收来自用户的控制事件信息。
在S308中,对所述控制事件信息进行解析获得用户输入指令。
最后,在S310中,基于所述用户输入指令来对所述现场设备进行控制。
以上参照图3说明了在执行根据本公开的现场设备的控制方法的过程中,在现场设备侧所执行的操作步骤。移动设备侧所执行的操作步骤如图4所示。图4为根据本公开实施例在移动设备处执行的现场设备的控制方法400的示例性过程的流程图,所述方法具体包括:
首先,在S402中,通过NFC协议接收来自现场设备的矢量图。
在S404中,基于所述矢量图在移动设备的屏幕上渲染图形用户界面。
在S406中,接收用户对所述图形用户界面的动作,基于所述动作生成控制事件信息。
在S408中,将所述控制事件信息通过NFC协议发送给现场设备。
图5示出了用于执行图3所示的现场设备的控制方法的现场设备500的示例性配置的框图。
在图5中,现场设备500包括:矢量编码模块502、发送模块504、接收模块506、解析模块508和控制模块510。
其中,矢量编码模块502被配置为将现场设备的用户界面编码为矢量图。
发送模块504被配置为采用NFC协议将所述矢量图发送出去。
接收模块506被配置为通过NFC协议接收来自用户的控制事件信息。
解析模块508被配置为对所述控制事件信息进行解析获得用户输入指令。
控制模块510基于所述用户输入指令来对所述现场设备进行控制。
图6示出了用于执行图4所示的现场设备的控制方法的移动设备600的示例性配置的框图。
在图6中,移动设备600包括:接收模块602、渲染模块604、事件生成模块606和发送模块608。
其中,接收模块602被配置为通过NFC协议接收来自现场设备的矢量图;
渲染模块604被配置为基于所述矢量图在移动设备的屏幕上渲染图形用户界面;
事件生成模块606被配置为接收用户对所述图形用户界面的动作,基于所述动作生成控制事件信息。
发送模块608被配置为将所述控制事件信息通过NFC协议发送给现场设备。
需要说明的是,图5所示的现场设备500和图6所示的移动设备600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5和图6所示的结构框图进行修改。
现场设备500和移动设备600的各个部分的操作和功能的细节例如可以与参照结合图1-4描述的本公开的现场设备的控制方法的实施例的相关部分相同或类似,这里不再详细描述。
在根据本发明的现场设备的控制方法中,在现场设备和移动设备之间传送的数据是矢量图(现场设备->移动设备)和用户事件(移动设备->现场设备),而不是业务数据或者位图数据,因此需要传输的数据量很小,从而可以采用提供的带宽较小的NFC通信协议来实现。
用户使用移动设备来呈现用户界面,而无需本地的HMI或者便携式HMI面板,因此具有良好的用户体验和低成本。
实际的用户界面寄主在现场设备上而不是一定设备上,这样对于用户的移动设备来说不存在后向兼容的问题。
当用户的移动设备移动至现场设备的NFC范围之内时,可以自动在移动设备上显示用户界面,无需进行配对或者连接。
如上参照图1至图6,对根据本公开的实施例的现场设备的控制方法以及现场设备和 移动设备的实施例进行了描述。以上所述的现场设备和移动设备的各个单元可以采用硬件实现,也可以采用软件或者硬件和软件的组合来实现。

上文对本说明书特定实施例进行了描述。其它实施例在所附权利要求书的范围内。在一些情况下,在权利要求书中记载的动作或步骤可以按照不同于实施例中的顺序来执行并且仍然可以实现期望的结果。另外,在附图中描绘的过程不一定要求示出的特定顺序或者连续顺序才能实现期望的结果。在某些实施方式中,多任务处理和并行处理也是可以的或者可能是有利的。
上述各流程和各系统结构图中不是所有的步骤和单元都是必须的,可以根据实际的需要忽略某些步骤或单元。上述各实施例中描述的装置结构可以是物理结构,也可以是逻辑 结构,即,有些单元可能由同一物理实体实现,或者,有些单元可能分别由多个物理实体实现,或者,可以由多个独立设备中的某些部件共同实现。
上面结合附图阐述的具体实施方式描述了示例性实施例,但并不表示可以实现的或者落入权利要求书的保护范围的所有实施例。在整个本说明书中使用的术语“示例性”意味着“用作示例、实例或例示”,并不意味着比其它实施例“优选”或“具有优势”。出于提供对所描述技术的理解的目的,具体实施方式包括具体细节。然而,可以在没有这些具体细节的情况下实施这些技术。在一些实例中,为了避免对所描述的实施例的概念造成难以理解,公知的结构和装置以框图形式示出。
