具体实施方式
本说明书提供的数据处理方法旨在为工业控制系统中的FPGA与I/O模块之间建立端到端的通信，并为FPGA与每个I/O模块之间建立多条通信链路，以在任一通信链路出现故障的情况下依然能保证FPGA与I/O模块之间的正常通信。
为使本说明书的目的、技术方案和优点更加清楚，下面将结合本说明书具体实施例及相应的附图对本说明书技术方案进行清楚、完整地描述。所描述的实施例仅是本说明书一部分实施例，而不是全部的实施例。基于本说明书中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本说明书保护的范围。
以下结合附图，详细说明本说明书各实施例提供的技术方案。
在本说明书中，本说明书实施例提供一种数据处理系统，该数据处理系统可以包括：工业控制系统中的第一单元以及第二单元。第一单元可以是指工业控制系统中用于控制各第二单元的组件，比如FPGA等。第二单元可以是指工业控制系统中用于监测和采集各工业设备运行过程中产生的数据的组件，比如I/O模块等。另外，第二单元还可以对工业控制系统中各工业设备运行时所需的数据进行配置。其中，各工业设备运行过程中产生的数据或所需的数据可以包括：输入的数字信号数据、输出的数字信号数据、输入的模拟信号数据、输出的模拟信号数据等，各工业设备运行过程中产生的数据或所需的数据可以包括：电压数据、电流数据、温度数据、湿度数据等。
在工业控制系统中，一个第一单元可以控制多个第二单元。在本说明书实施例中， 工业控制系统中包括与每个第一单元对应的多个第一收发器，以及与每个第二单元对应的多个第二收发器。第一收发器和第二收发器的结构相同，第一收发器和第二收发器可以是RS-485收发器。若第一收发器和第二收发器为RS-485收发器，则第一单元与第二单元之间的通信协议为RS-485协议。另外，由于RS-485收发器采用的是半双工的通信模式，所以，RS-485收发器无法同时接收数据和发送数据，因此，RS-485收发器在进行数据收发时需要进行收发状态的切换。
针对每个第二单元，该第二单元与第一单元之间存在多条通信链路，针对每条通信链路，该通信链路是由该第二单元的一个第二收发器和第一单元的一个第一收发器连接所构成的。这样，当第一单元与任一第二单元之间的通信链路存在异常时，不会影响其他的第二单元与第一单元之间的通信。另外，针对每个第二单元与第一单元之间的通信链路，若该第二单元与第一单元之间的一条通信链路存在异常时，可以采用其他通信链路进行通信，以保证该第二单元与第一单元能够正常通信，以此提高工业控制系统的通信稳定性。
基于上述对第一单元与各第二单元之间的通信链路的描述，本说明书实施例提供第一单元与各第二单元之间的多条通信链路的结构示意图，如图1所示。
在图1中，以1个FPGA和3个I/O模块为例，针对每个I/O模块，FPGA可以与该I/O模块之间存在两条通信链路。
接下来，对第一单元与第二单元之间的通信过程进行说明。
第一单元可以响应于接收到数据操作请求，确定需要执行数据操作的第二单元，作为目标第二单元。然后，通过第一单元与目标第二单元之间的多条通信链路，将数据操作请求发送给目标第二单元。其中，数据操作请求中可以携带有需要执行数据操作的第二单元的标识、需要执行数据操作的第二单元的通信地址以及数据操作指令。另外，数据操作请求可以包括：数据采集请求、数据配置请求等。
具体的，第一单元可以在接收到数据操作请求之后，可以先从数据操作请求中确定出需要执行数据操作的第二单元，作为目标第二单元。然后，可以从多个第一收发器中确定出与目标第二单元对应连接的各第一收发器，作为各目标第一收发器。之后，将各目标第一收发器的收发状态由数据接收状态切换为数据发送状态。最后，可以根据目标第二单元的通信地址以及第一单元与目标第二单元之间的多条通信链路对应的通信协议，将数据操作请求发送给目标第二单元。即，通过第一单元与目标第二单元之间的通 信链路，将数据操作请求发送给目标第二单元。在将数据操作请求发送给目标第二单元之后，第一单元可以将各目标第一收发器的收发状态由数据发送状态切换为数据接收状态。
目标第二单元可以通过多个第二收发器接收数据操作请求，并根据数据操作请求中的数据操作指令，确定待操作的目标数据，并对目标数据进行处理，得到处理结果，并将处理结果发送给第一单元。其中，针对不同的数据操作请求或数据操作指令，对目标数据进行处理的处理方式也不同，对应的处理结果也不同。比如：针对数据采集请求或数据采集指令，可以对目标数据进行采集并汇总，得到汇总后的数据集(即，处理结果)。针对数据配置请求或数据配置指令，对目标数据进行重新配置，得到重新配置后的数据，并将配置完成信息作为处理结果。
具体的，目标第二单元检测多个第二收发器是否接收到数据操作请求。若多个第二收发器均接收到数据操作请求，依次对数据操作请求中的数据操作指令进行执行。若多个第二收发器中只有部分第二收发器接收到数据操作请求，只对部分第二收发器接收的数据操作请求中的数据操作指令进行执行。
其中，目标第二单元包含的多个第二收发器可以包括：主第二收发器、辅第二收发器。辅第二收发器可以是多个。其中，主第二收发器的优先级高于辅第二收发器的优先级，主第二收发器和辅第二收发器是互为冗余的第二收发器。
进一步，目标第二单元检测主第二收发器是否接收到第一单元通过第一单元与目标第二单元之间的多条通信链路所发送的数据操作请求，若主第二收发器接收到数据操作请求，将数据操作请求保存到第一缓存区。若主第二收发器未接收到数据操作请求，检测辅第二收发器是否接收到数据操作请求。若辅第二收发器接收到数据操作请求，将数据操作请求保存到第二缓存区。其中，第一缓存区用于缓存通过主第二收发器所接收到的数据，第二缓存区用于缓存通过辅第二收发器所接收到的数据。
目标第二单元检测第一缓存区中是否包含有数据操作请求，若第一缓存区中包含有数据操作请求，根据第一单元与目标第二单元之间的通信协议，对数据操作请求进行解析，得到数据操作指令。然后，将数据操作指令保存到第一任务队列中。若第一缓存区中未包含有数据操作请求，检测第二缓存区中是否包含有数据操作请求，若第二缓存区中包含有数据操作请求，根据第一单元与目标第二单元之间的通信协议，对数据操作请求进行解析，得到数据操作指令。然后，将数据操作指令保存到第二任务队列中。其中，第一任务队列和第二任务队列可以是用于保存待执行的任务指令的环形队列。任务指令 可以是指数据操作指令。
再进一步，检测第一任务队列中是否包含有数据操作指令，若第一任务队列中包含有数据操作指令，可以根据数据操作指令，确定待操作的目标数据。然后，对目标数据进行处理，得到处理结果。
若第一任务队列中不包含数据操作指令，检测第二任务队列中是否包含数据操作指令。若第二任务队列中包含数据操作指令，可以根据数据操作指令，确定待操作的目标数据，并对目标数据进行处理，得到处理结果。
以采集温度数据为例，第一单元将数据采集请求通过第一单元与目标第二单元之间的多条通信链路发送给目标第二单元。目标第二单元根据数据采集请求中的数据采集指令，确定出需要采集的温度数据(即，目标数据)，然后，获取各温度数据并进行汇总，得到针对温度数据的数据集(即，处理结果)。最后，将数据集发送给第一单元。
在目标第二单元得到处理结果之后，将多个第二收发器的收发状态由数据接收状态切换为数据发送状态。然后，可以通过多个第二收发器将处理结果分别发送给第一单元。目标第二单元在将处理结果发送给第一单元之后，可以将多个第二收发器的收发状态由数据发送状态切换为数据接收状态。
需要说明的是，目标第二单元需要对主第二收发器和辅第二收发器所接收的数据操作指令都执行，即，先后对数据操作指令进行执行，并先后将生成处理结果发送给第一单元。这样，可以避免第一单元和第二单元之间的任意一条通信链路存在异常时，第二单元都能将处理结果发送给第一单元。
在目标第二单元将处理结果发送给第一单元之后，第一单元可以通过各目标第一收发器接收目标第二单元发送的处理结果，并根据处理结果，确定出针对数据操作请求的响应策略，并执行确定出的响应策略。
具体的，第一单元在将各目标第一收发器的收发状态由数据发送状态切换为数据接收状态后，第一单元可以在预设时长内，检测各目标第一收发器是否接收到目标第二单元发送的处理结果。其中，预设时长大于目标第二单元执行数据操作指令的最大执行时长。
第一单元若检测到各目标第一收发器均接收到目标第二单元发送的处理结果，可以根据接收到的第一个处理结果，确定出针对数据操作请求的响应策略，并执行响应策略。同时，删除在接收到第一个处理结果之后接收到的处理结果，以减小第一单元的缓存压 力。其中，响应策略可以包括：将处理结果转发给发送数据操作请求的设备、向发送数据操作请求的设备返回数据操作完成信息等至少一种策略。
若检测到各目标第一收发器均未接收到目标第二单元发送的处理结果，确定出针对数据操作请求的超时处理策略，并执行超时处理策略。其中，超时处理策略可以包括：向目标第二单元重新发送数据操作请求、向发送数据操作请求的设备返回超时提示信息等至少一种策略。
另外，在第一单元接收到处理结果之后，可以将各目标第一收发器的收发状态由数据接收状态切换为数据发送状态。
继续沿用上例，在目标第二单元将数据集发送的第一单元之后，第一单元在接收到数据集之后，可以将数据集转发给发送数据采集请求的设备。
需要说明的是，针对第一单元，多个第一收发器的收发状态默认为数据发送状态，针对第二单元，多个第二收发器的收发状态默认为数据接收状态。
基于上述对第一单元和第二单元之间的通信过程的描述，图2为本说明书实施例提供的一种数据处理方法的流程示意图，该数据处理方法应用于工业控制系统中的第一单元，该数据处理方法包括：
S200：响应于接收到数据操作请求，确定需要执行数据操作的第二单元，作为目标第二单元。
S202：通过所述第一单元与所述目标第二单元之间的多条通信链路，将所述数据操作请求发送给所述目标第二单元，以使所述目标第二单元通过所述多个第二收发器接收所述数据操作请求，并根据所述数据操作请求中的数据操作指令，对待操作的目标数据进行处理，得到处理结果，并将所述处理结果发送给所述第一单元。
S204：接收所述目标第二单元发送的所述处理结果，并根据所述处理结果，执行针对所述数据操作请求的响应策略。
在本说明书实施例中，该数据处理方法应用于工业控制系统中的第一单元，第一单元对应设置多个第一收发器。工业控制系统中还包括多个第二单元，针对每个第二单元，该第二单元对应设置多个第二收发器，该第二单元与第一单元之间存在多条通信链路，针对每条通信链路，该通信链路是由该第二单元的一个第二收发器和第一单元的一个第一收发器连接所构成的。
在第一单元与第二单元进行通信时，第一单元响应于数据操作请求，确定需要执行数据操作的第二单元，作为目标第二单元。然后，通过第一单元与目标第二单元之间的多条通信链路，将数据操作请求发送给目标第二单元，以使目标第二单元通过多个第二收发器接收数据操作请求，并根据数据操作请求中的数据操作指令，对待操作的目标数据进行处理，得到处理结果，并将处理结果发送给第一单元。
第一单元接收目标第二单元发送的处理结果，并根据处理结果，执行针对数据操作请求的响应策略。
在接收处理结果时，从多个第一收发器中确定出与目标第二单元对应连接的各第一收发器，作为各目标第一收发器。将各目标第一收发器的收发状态由数据发送状态切换为数据接收状态。然后，在预设时长内，检测各目标第一收发器是否接收到目标第二单元发送的处理结果。其中，预设时长大于目标第二单元执行数据操作指令的最大执行时长。
若检测到各目标第一收发器均接收到目标第二单元发送的处理结果，根据接收到的第一个处理结果，执行针对数据操作请求的响应策略，并删除在接收到第一个处理结果之后接收到的处理结果。最后，将各目标第一收发器的收发状态由数据接收状态切换为数据发送状态。
若检测到各目标第一收发器均未接收到目标第二单元发送的处理结果，确定出针对数据操作请求的超时处理策略，并执行超时处理策略。
另外，基于上述对第一单元和第二单元之间的通信过程的描述，图3为本说明书实施例提供的另一种数据处理方法的流程示意图，该数据处理方法应用于工业控制系统中的第二单元，该数据处理方法包括：
S300：通过与第二单元对应的多个第二收发器接收第一单元通过所述第一单元与所述第二单元之间的多条通信链路所发送的数据操作请求，其中，所述数据操作请求是所述第一单元所接收到的。
S302：根据所述数据操作请求中的数据操作指令，确定待操作的目标数据，并对所述目标数据进行处理，得到处理结果。
S304：通过所述多个第二收发器，将所述处理结果发送给所述第一单元，以使所述第一单元根据接收到的处理结果，执行针对所述数据操作请求的响应策略。
在本说明书实施例中，该数据处理方法应用于工业控制系统中任意的第二单元。工 业控制系统中还包括第一单元，第一单元对应设置多个第一收发器。针对每个第二单元，该第二单元对应设置多个第二收发器，该第二单元与第一单元之间存在多条通信链路，针对每条通信链路，该通信链路是由该第二单元的一个第二收发器和第一单元的一个第一收发器连接所构成的。其中，多个第二收发器可以包括：主第二收发器、辅第二收发器。
需要说明的是，任意的第二单元可以对应于上述的目标第二单元。
在第一单元与第二单元进行通信时，第二单元可以通过多个第二收发器接收第一单元通过第一单元与第二单元之间的多条通信链路所发送的数据操作请求。其中，数据操作请求是第一单元所接收到的。
第二单元可以根据数据操作请求中的数据操作指令，确定待操作的目标数据，并对目标数据进行处理，得到处理结果。通过多个第二收发器，将处理结果发送给第一单元，以使第一单元根据接收到的处理结果，执行针对数据操作请求的响应策略。
在第二单元接收数据操作请求时，第二单元可以检测主第二收发器是否接收到第一单元通过第一单元与第二单元之间的多条通信链路所发送的数据操作请求。
若主第二收发器接收到数据操作请求，将数据操作请求保存到第一缓存区，并对数据操作请求进行解析，得到数据操作指令，将数据操作指令保存到第一任务队列中。
若主第二收发器未接收到数据操作请求，检测辅第二收发器是否接收到数据操作请求。

若第一任务队列中不包含数据操作指令，检测第二任务队列中是否包含数据操作指令，若第二任务队列中包含数据操作指令，根据数据操作指令，确定待操作的目标数据，并对目标数据进行处理，得到处理结果。
最后，第二单元可以通过多个第二收发器，将处理结果发送给第一单元，以使第一单元根据接收到的处理结果，确定针对数据操作请求的响应策略。

本说明书还提供了一种计算机可读存储介质，所述存储介质存储有计算机程序，所述计算机程序被处理器执行时可用于执行上述图2和图3提供的数据处理方法。
基于图2和图3所示的数据处理方法，本说明书实施例还提供了图6所示的电子设备的结构示意图。如图6，在硬件层面，该电子设备包括处理器、内部总线、网络接口、内存以及非易失性存储器，当然还可能包括其他业务所需要的硬件。处理器从非易失性存储器中读取对应的计算机程序到内存中然后运行，以实现上述图3和图2所述的数据处理方法。
当然，除了软件实现方式之外，本说明书并不排除其他实现方式，比如逻辑器件抑或软硬件结合的方式等等，也就是说以下处理流程的执行主体并不限定于各个逻辑单元，也可以是硬件或逻辑器件。
在20世纪90年代，对于一个技术的改进可以很明显地区分是硬件上的改进(例如，对二极管、晶体管、开关等电路结构的改进)还是软件上的改进(对于方法流程的改进)。然而，随着技术的发展，当今的很多方法流程的改进已经可以视为硬件电路结构的直接改进。设计人员几乎都通过将改进的方法流程编程到硬件电路中来得到相应的硬件电路结构。因此，不能说一个方法流程的改进就不能用硬件实体模块来实现。例如，可编程逻辑器件(Programmable Logic Device,PLD)(例如现场可编程门阵列(Field Programmable Gate Array，FPGA))就是这样一种集成电路，其逻辑功能由用户对器件编程来确定。由设计人员自行编程来把一个数字系统“集成”在一片PLD上，而不需要请芯片制造厂商来设计和制作专用的集成电路芯片。而且，如今，取代手工地制作集成电路芯片，这种编程也多半改用“逻辑编译器(logic compiler)”软件来实现，它与程序开发撰写时所用的软件编译器相类似，而要编译之前的原始代码也得用特定的编程语言来撰写，此称之为硬件描述语言(Hardware Description Language，HDL)，而HDL也并非仅有一种，而是有许多种，如ABEL(Advanced Boolean Expression Language)、AHDL(Altera Hardware Description Language)、Confluence、CUPL(Cornell University Programming Language)、HDCal、JHDL(Java Hardware Description Language)、Lava、Lola、MyHDL、PALASM、RHDL(Ruby Hardware Description Language)等，目前最普遍使用的是VHDL(Very-High-Speed Integrated Circuit Hardware Description Language)与Verilog。本领域技术人员也应该清楚，只需要将方法流程用上述几种硬件描述语言稍作逻辑编程并编程到集成电路中，就可以很容易得到实现该逻辑方法流程的硬件电路。
控制器可以按任何适当的方式实现，例如，控制器可以采取例如微处理器或处理器 以及存储可由该(微)处理器执行的计算机可读程序代码(例如软件或固件)的计算机可读介质、逻辑门、开关、专用集成电路(Application Specific Integrated Circuit，ASIC)、可编程逻辑控制器和嵌入微控制器的形式，控制器的例子包括但不限于以下微控制器：ARC 625D、Atmel AT91SAM、Microchip PIC18F26K20以及Silicone Labs C8051F320，存储器控制器还可以被实现为存储器的控制逻辑的一部分。本领域技术人员也知道，除了以纯计算机可读程序代码方式实现控制器以外，完全可以通过将方法步骤进行逻辑编程来使得控制器以逻辑门、开关、专用集成电路、可编程逻辑控制器和嵌入微控制器等的形式来实现相同功能。因此这种控制器可以被认为是一种硬件部件，而对其内包括的用于实现各种功能的装置也可以视为硬件部件内的结构。或者甚至，可以将用于实现各种功能的装置视为既可以是实现方法的软件模块又可以是硬件部件内的结构。
上述实施例阐明的系统、装置、模块或单元，具体可以由计算机芯片或实体实现，或者由具有某种功能的产品来实现。一种典型的实现设备为计算机。具体的，计算机例如可以为个人计算机、膝上型计算机、蜂窝电话、相机电话、智能电话、个人数字助理、媒体播放器、导航设备、电子邮件设备、游戏控制台、平板计算机、可穿戴设备或者这些设备中的任何设备的组合。
为了描述的方便，描述以上装置时以功能分为各种单元分别描述。当然，在实施本说明书时可以把各单元的功能在同一个或多个软件和/或硬件中实现。
本领域内的技术人员应明白，本说明书的实施例可提供为方法、系统、或计算机程序产品。因此，本说明书可采用完全硬件实施例、完全软件实施例、或结合软件和硬件方面的实施例的形式。而且，本说明书可采用在一个或多个其中包含有计算机可用程序代码的计算机可用存储介质(包括但不限于磁盘存储器、CD-ROM、光学存储器等)上实施的计算机程序产品的形式。
本说明书是参照根据本说明书实施例的方法、设备(系统)、和计算机程序产品的流程图和/或方框图来描述的。应理解可由计算机程序指令实现流程图和/或方框图中的每一流程和/或方框、以及流程图和/或方框图中的流程和/或方框的结合。可提供这些计算机程序指令到通用计算机、专用计算机、嵌入式处理机或其他可编程数据处理设备的处理器以产生一个机器，使得通过计算机或其他可编程数据处理设备的处理器执行的指令产生用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的装置。
这些计算机程序指令也可存储在能引导计算机或其他可编程数据处理设备以特定 方式工作的计算机可读存储器中，使得存储在该计算机可读存储器中的指令产生包括指令装置的制造品，该指令装置实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能。
这些计算机程序指令也可装载到计算机或其他可编程数据处理设备上，使得在计算机或其他可编程设备上执行一系列操作步骤以产生计算机实现的处理，从而在计算机或其他可编程设备上执行的指令提供用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的步骤。
在一个典型的配置中，计算设备包括一个或多个处理器(CPU)、输入/输出接口、网络接口和内存。
内存可能包括计算机可读介质中的非永久性存储器，随机存取存储器(RAM)和/或非易失性内存等形式，如只读存储器(ROM)或闪存(flash RAM)。内存是计算机可读介质的示例。
计算机可读介质包括永久性和非永久性、可移动和非可移动媒体可以由任何方法或技术来实现信息存储。信息可以是计算机可读指令、数据结构、程序的模块或其他数据。计算机的存储介质的例子包括，但不限于相变内存(PRAM)、静态随机存取存储器(SRAM)、动态随机存取存储器(DRAM)、其他类型的随机存取存储器(RAM)、只读存储器(ROM)、电可擦除可编程只读存储器(EEPROM)、快闪记忆体或其他内存技术、只读光盘只读存储器(CD-ROM)、数字多功能光盘(DVD)或其他光学存储、磁盒式磁带，磁带磁磁盘存储或其他磁性存储设备或任何其他非传输介质，可用于存储可以被计算设备访问的信息。按照本文中的界定，计算机可读介质不包括暂存电脑可读媒体(transitory media)，如调制的数据信号和载波。
还需要说明的是，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、商品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、商品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、商品或者设备中还存在另外的相同要素。
本领域技术人员应明白，本说明书的实施例可提供为方法、系统或计算机程序产品。因此，本说明书可采用完全硬件实施例、完全软件实施例或结合软件和硬件方面的实施例的形式。而且，本说明书可采用在一个或多个其中包含有计算机可用程序代码的计算 机可用存储介质(包括但不限于磁盘存储器、CD-ROM、光学存储器等)上实施的计算机程序产品的形式。
本说明书可以在由计算机执行的计算机可执行指令的一般上下文中描述，例如程序模块。一般地，程序模块包括执行特定任务或实现特定抽象数据类型的例程、程序、对象、组件、数据结构等等。也可以在分布式计算环境中实践本说明书，在这些分布式计算环境中，由通过通信网络而被连接的远程处理设备来执行任务。在分布式计算环境中，程序模块可以位于包括存储设备在内的本地和远程计算机存储介质中。
本说明书中的各个实施例均采用递进的方式描述，各个实施例之间相同相似的部分互相参见即可，每个实施例重点说明的都是与其他实施例的不同之处。尤其，对于系统实施例而言，由于其基本相似于方法实施例，所以描述的比较简单，相关之处参见方法实施例的部分说明即可。
以上所述仅为本说明书的实施例而已，并不用于限制本说明书。对于本领域技术人员来说，本说明书可以有各种更改和变化。凡在本说明书的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本说明书的权利要求范围之内。
