具体实施方式
现在将参考示例实施方式讨论本文描述的主题。应该理解，讨论这些实施方式只是为了使得本领域技术人员能够更好地理解从而实现本文描述的主题，并非是对权利要求书中所阐述的保护范围、适用性或者示例的限制。可以在不脱离本公开内容的保护范围的情况下，对所讨论的元素的功能和排列进行改变。各个示例可以根据需要，省略、替代或者添加各种过程或组件。例如，所描述的方法可以按照与所描述的顺序不同的顺序来执行，以及各个步骤可以被添加、省略或者组合。另外，相对一些示例所描述的特征在其它例子中也可以进行组合。
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。
如本文中使用的，术语“变送器的测量信息”是指变送器所监测到的测量信号或者变送器的测量状态信息，所述测量状态信息例如可以是变送器的工作状态正常或者异常等。
图1示出了现有技术中的变送器测量系统的结构的一个示例的示意图。
如图1所示，变送器111和112与分布式I/O设备130连接，例如，变送器111和112通过HART总线(HART网络)来与分布式I/O设备130连接，从而变送器111和112与分布式I/O设备130之间采用HART协议来进行数据传输。变送器111例如可以是不具有显示屏的温度变送器，以及变送器112可以是具有显示屏的压力传感器。在图1中，虽然示出的是仅仅2个变送器，在其它示例结构中，也可以包括更多或更少数目的变送器。
在本公开中，变送器是指将与其直接连接的传感器的测量信息转换成标准信号的设备。例如，压力变送器112是一种将压力转换成气动信号或 电动信号进行控制和远传的设备。它能将测压元件传感器感受到的气体、液体等物理压力参数转变成标准的电信号(比如，4～10mADC等)，以供给指示报警仪、记录仪、调节器等二次仪表进行测量、指示和过程调节。
分布式I/O设备130通过比如采用PROFIBUS DP协议的总线网络120连接到具有显示屏的设备管理器110。在工厂自动化的应用中，设备管理器110可以使用PROFIBUS DP协议来在总线网络120上与连接到总线网络120上的比如分布式I/O设备130的其它设备之间进行数据通信，以获取各个变送器和/或其它过程设备的信息。分布式I/O设备130例如可以是ET100M或者ET100S。
设备管理器110例如可以是SIMATIC PDM。SIMATIC PDM是用于组态、参数分配、调试、诊断以及维护智能过程设备和自动化部件的制造商通用工具。SIMATIC PDM用户界面是基于微软Windows标准指南设计的。它提供菜单结构、工具栏以及浏览器视图，从而使得在参数组之间进行浏览变得更为简单。利用SIMATIC PDM，可以使用单一的软件程序来对不同制造商生产的各种现场设备进行组态，并且可以对过程设备数据进行方便的设置、修改、检查似真性、管理和仿真。此外，还可以在线监视和显示过程设备所监测到的过程值、报警信息和状态信号。
变送器111和112所监测到的数据通过HART总线传送到分布式I/O设备130，然后经由总线网络120传送到设备管理器110，以在设备管理器110的显示屏上进行显示。
在图1中示出的变送器测量系统中，针对不具有显示屏的变送器，在操作人员需要了解该变送器的测量信息时，操作人员需要来到设备管理器110面前，在设备管理器110的显示屏上观看该变送器的测量信息，或者例如通过远程通信的方式来从设备管理器110获取该变送器的测量信息。在这种情况下，由于变送器和设备管理器110之间的距离通常比较远，从而使得操作人员从设备管理器110中获取变送器的测量信息非常不方便，并且也无法及时准确地了解这些不具有显示屏的变送器的工作状况。
为了使得操作人员能够在无需从设备管理器获取变送器的测量信息或者去设备管理器的显示屏上查看变送器的测量信息的情况下，及时准确地了解变送器(比如，不具有显示屏的变送器或者与操作人员相距较远的具 有显示屏的变送器)的测量信息，本公开提供了一种用于在第一变送器的显示屏上显示至少一个第二变送器的测量信息的系统。利用该系统，通过在具有显示屏的第一变送器、至少一个第二变送器以及分布式I/O设备之间配置好测量信息传输路径，并且至少一个第二变送器的测量信息经由所配置好的测量信息传输路径来经由分布式I/O设备传送到第一变送器。然后，在第一变送器接收到用于显示至少一个第二变送器的测量信息的显示指令时，在第一变送器上的显示屏上显示出对应的第二变送器的测量信息，从而使得操作人员能够在无需从设备管理器获取测量信息或者去设备管理器的显示屏上查看变送器的测量信息的情况下，及时准确地了解到第二变送器的测量信息，并且进而获取第二变送器的工作状况。
图2示出了根据本公开的实施例的用于在第一变送器的显示屏上显示至少一个第二变送器的测量信息的系统(下文中简称为屏幕共享显示系统)1的方框图。
如图2所示，屏幕共享显示系统1包括第一变送器20、至少一个第二变送器30和分布式I/O设备40。第一变送器20具有显示屏210。显示屏210用于显示第一变送器20所监测到的测量信息。第一变送器20例如可以是压力变送器。至少一个第二变送器30可以包括一个或多个第二变送器30，分别用于感测对应的测量信息。至少一个第二变送器30例如可以是温度变送器等。在本公开中，第二变送器30可以是不具有显示屏的变送器，也可以是具有显示屏的变送器，例如，与操作人员相距较远的具有显示屏的变送器或者任意具有显示屏的变送器，由此使得能够显示不具有显示屏的变送器上的测量信息，或者能够显示操作人员不易到达的距离较远的具有显示屏的变送器上的测量信息，或者能够在单个变送器上实现多个变送器的测量信息显示。
在本公开中，第一变送器20、至少一个第二变送器30和分布式I/O设备40可以是HART设备，并且第一变送器20和至少一个第二变送器30与分布式I/O设备40之间通过HART总线连接。第一变送器20和至少一个第二变送器30与分布式I/O设备40之间预先配置好数据传输路径，并且采用HART(Highway addressable remote transducer)协议来按照预先配置的数据传输路径进行数据通信。
HART协议是可寻址远程传感器高速通道的开放通信协议。HART协议采用基于Bell102标准的FSK频移键控信号，在低频的4-10mA模拟信号上叠加幅度为0.5mA的音频数字信号进行双向数字通讯，数据传输率为1.2kbps。由于FSK信号的平均值为0，不影响传送给控制系统模拟信号的大小，保证了与现有模拟系统的兼容性。
在本公开中，所述预先配置的数据传输路径是依据用户任务需求手动或者自动地设置的测量信息传输路径。例如，可以将距离操作人员较近的具有显示屏的变送器选定为第一变送器20，以及将操作人员需要进行测量信息监控的至少一个变送器作为至少一个第二变送器30。然后，在所选定的第一变送器20、所选定的至少一个第二变送器30和关联分布式I/O设备40之间预先配置好数据传输路径，由此使得至少一个第二变送器30上监测到的测量信息能够按照预先配置好的数据传输路径传送到第一变送器20，从而实现在第一变送器20的显示屏上进行显示。
此外，第一变送器20还被配置为在获取到用于显示至少一个第二变送器30的测量信息的显示指令后，在第一变送器20的显示屏210上显示至少一个第二变送器30的测量信息，从而实现第一变送器20的显示屏210在至少一个第二变送器30之间的屏幕共享显示。这里要说明的是，所述至少一个第二变送器30可以是预先与第一变送器20之间配置好数据传输路径的第二变送器30中的部分或者全部。
此外，在本公开的另一示例中，屏幕共享显示系统1还可以包括报警器(未示出)。报警器可以在当前显示屏210上所显示出的测量信息指示信息异常时，发送报警信号。比如：当前所显示的温度变送器的温度测量信息异常时，报警器会发出温度报警信号，比如，发送声音告警或者闪烁指示灯，以提醒工程师们对温度变送器进行维修。
图3示出了根据本公开的实施例的第一变送器20的一个示例的结构方框图。如图3所示，第一变送器20包括显示屏210和屏幕共享显示装置220。
屏幕共享显示装置220被配置为在获取到用于显示至少一个第二变送器30的测量信息的显示指令后，在第一变送器20的显示屏210上显示该至少一个第二变送器30的测量信息。这里，至少一个第二变送器30的测量信息可以是按照预先配置的数据传输路径来经由分布式I/O设备40获取 的。例如，在第二变送器30监测到测量信息后，第二变送器30可以按照预先配置的数据传输路径将所监测到的测量信息传送到分布式I/O设备40，并且存储到分布式I/O设备40中，以供第一变送器20接收到显示指令后获取。或者，分布式I/O设备40可以在从第二变送器30中接收到测量信息，然后将所接收的测量信息按照预先配置的数据传输路径转发给第一变送器20，由第一变送器20进行存储以供后续显示使用。
所述显示指令可以是从第一变送器20的外部获取，例如，在一个示例中，所述显示指令可以是从第二变送器30上发出并经由分布式I/O设备40发送到第一变送器20，或者从分布式I/O设备40发送到第一变送器20。或者，在另一示例中，第一变送器20可以包括至少一个显示指令按钮230。所述显示指令是通过操作第一变送器20上的至少一个显示指令按钮230来获取的。这里要说明的是，所述显示指令可以是对应于预先配置好数据传输路径的第二变送器30中的一个变送器、部分变送器或者全部变送器。
至少一个显示指令按钮230可以设置在第一变送器20的显示屏210上或者设置在第一变送器20的其它合适位置处，并且被用户使用来发起针对至少一个第二变送器30的测量信息的显示指令。例如，至少一个显示指令按钮230可以被设计为是显示屏210上的硬件按钮装置或虚拟按钮，并且至少一个显示指令按钮230中的每一个按钮被设置为与至少一个第二变送器30中的一个第二变送器对应，从而在该显示指令按钮230被用户操作时，发出针对该对应的第二变送器的测量信息的显示指令。或者，至少一个显示指令按钮230中的每一个按钮也可以被设置为与至少一个第二变送器30中的多个第二变送器对应，从而在该显示指令按钮230被用户操作时，触发针对所对应的多个第二变送器中的变送器选择操作菜单，以供用户进行变送器选择，并且在用户选择好目标第二变送器后，发出针对所选择的第二变送器的测量信息的显示指令。
至少一个第二变送器30的测量信息可以是在获取到所述显示指令后由第一变送器20从第二变送器30或分布式I/O设备40获取的，或者是与所述显示指令一起发送给第一变送器20的，或者是在获取到所述显示指令之前由第一变送器20从第二变送器30或分布式I/O设备40获取的。
在至少一个第二变送器30的测量信息是在获取到所述显示指令之前由 第一变送器20从第二变送器30或分布式I/O设备40获取的情况下，第一变送器20还可以包括测量信息数据库240。测量信息数据库240用于对第二变送器30的测量信息和第二变送器30的唯一标识信息进行相关联地存储。所述唯一标识信息例如可以是第二变送器30的设备标识信息、位置信息或者能够唯一标识该第二变送器的其他唯一标识信息。相应地，所述显示指令可以包括至少一个第二变送器30的唯一标识信息。在接收到所述显示指令后，第一变送器20基于所述显示指令中的包括的第二变送器30的唯一标识信息，从测量信息数据库240中获取对应的第二变送器30的测量信息，并进行显示。
此外，在本公开的另一示例中，所述测量信息可以是指在当前预定时间段内的测量信息，比如：当前10秒内的测量信息。
图4示出了根据本公开的实施例的屏幕共享显示装置220的一个示例的方框图。如图4所示，屏幕共享显示装置220包括测量信息获取单元221、显示指令获取单元223和显示单元225。
测量信息获取单元221被配置为获取至少一个第二变送器30的测量信息。显示指令获取单元223被配置为获取用于显示至少一个第二变送器30的测量信息的显示指令。
在本公开的一个示例中，测量信息获取单元221可以是在获取到所述显示指令后，从第二变送器30或分布式I/O设备40获取至少一个第二变送器30的测量信息。在另一示例中，测量信息获取单元221可以是与所述显示指令一起从第二变送器30或者分布式I/O设备40获取至少一个第二变送器30的测量信息。或者，测量信息获取单元221可以是在获取到所述显示指令之前，从第二变送器30或分布式I/O设备40获取至少一个第二变送器30的测量信息。
