Description

数据传输方法和装置 技术领域
本发明涉及通信技术领域，尤其涉及数据传输方法和装置。
背景技术
目前，随着通信技术的发展，物联网成为新一代信息技术的趋势。物联网可以利用各种通信技术，将传感器、控制器、设备等连在一起，形成物与物相连，从而实现信息化、远程管理控制和智能化的网络。
在某些物联网(例如工业物联网)中，由于物联网设备的生产厂商、物联网设备的类型等差异，会导致物联网中数据传输的差异，即物联网中会存在多种数据传输协议实现数据传输。因此，物联网中负责继续数据汇集的中间件设备、负责数据分析处理的服务设备可以连接采用多个协议进行通信的物联网设备，所述协议可以为：传输控制协议(Transmission Control Protocol，TCP)/因特网协议(Internet Protocol，IP)、用于过程控制的对象连接与嵌入(Object Linking andEmbedding，OLE)(OLE for Process Control，OPC)协议、OPC统一架构(OPC Unified Architecture，OPC UA)协议、S7协议、Modbus协议等。因此中间件设备或服务设备作为数据接收设备，需要维护多种协议，并针对每种协议的数据报文，采用相应的协议接收。
由于传统的控制层和数据层的紧密耦合，导致物联网中的数据接收设备需要针对使用每种协议的物联网设备，需要维护相应的协议以便接收数据。因此，在物联网部署、扩展或维护的过程中，数据接收设备均需要根据连接的物联网设备使用的协议，适应性调整自身维护的协议，造成协议使用灵活性较差，进而提高了数据接收设备维护多个协议复杂度。

具体实施方式
为了使本发明实施例的目的、技术方案和优点更加清楚明白，以下参照附图本发明实施例进一步详细说明。其中，后续描述的实施例仅仅是本发明实施例的一部分，而非全部的实施例。
本发明实施例提供一种数据传输方法和装置，用以解决现有技术中协议使用灵活性较差 的问题。其中，由于方法及装置解决问题的原理相似，因此装置与方法的实施可以相互参见，重复之处不再赘述。
在本发明实施例中，数据接收设备获取连接自身的目标输入端口的目标物联网设备采用的目标协议的信息后，确定该目标协议，并根据所述目标协议，对该目标物联网设备通过该目标输入端口发送的第一数据报文进行解封装，得到数据。在该方案中，数据接收设备无需预先为目标物联网设备配置目标协议，而是可以自适应地根据目标物联网设备采用的目标协议的信息确定目标协议，因此，通过该方案，可以提高数据接收设备中协议的使用灵活性，从而可以降低数据接收设备维护多个协议的复杂度。
以下对本发明实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
1)、物联网设备，为物联网中的提供数据连通性的设备，或数据生成设备。在不同的场景中，物联网设备也不同。例如物联网设备可以为传统的物联网设备中的手持式设备、车载设备、可穿戴设备、计算设备等。又例如物联网设备可以为工业物联网设备中的各种传感器、温度计、以及各种机器等。
其中，该物联网设备在向物联网中的其他设备发送数据时，均需要采用相应的协议对数据进行封装。显然，不同的物联网设备采用的协议可能不同。
2)、数据接收设备，为物联网设备中用于接收物联网设备的数据的设备，例如数据采集网关等，具有数据汇聚功能的汇聚设备，以及实现数据服务功能的服务器等。可选的，当数据接收设备为还需要向上一层设备(如服务器)上传接收的数据的数据采集网关或汇聚设备时，所述数据接收设备还可以为称为中间件。
3)、协议，为通信双方必须遵循的规则和约定。协议定义了通信双方传输数据使用的格式，以及通信双方处理数据的方法。通信发送方需要将待发送的数据采用协议封装成数据报文，才能实现数据传输，相应的，通信接收方同样需要接收到数据报文后，只有采用该协议对数据报文进行解封装，才能得到通信发送方发送的数据。
目前，由于物联网设备的生产厂商、物联网设备的类型等差异，导致物联网中存在多种协议，例如，TCP/IP、OPC协议、OPC UA协议、S7协议、Modbus协议等等。
4)、连接模型，可以部署在数据接收设备中。其中，该连接模型中包含连接数据接收设备每个输入端口的物联网设备采用的协议的信息，即连接模型规定了每个输入端口与连接该输入端口的物联网设备采用的协议的信息的对应关系。可选的，连接模型中还包含：每个输入端口连接的物联网设备的设备信息(例如：设备标识、IP地址等)，即该连接模型还规定了每个输入端口与连接该输入端口的物联网设备的设备信息的对应关系。
通过该连接模型，数据接收设备可以确定：当前物联网的网络拓扑情况、需要向数据接 收设备发送数据的物联网设备采用的协议，以及连接的物联网设备的设备信息等。
可选的，连接模型可以为用户根据实际物联网现场的网络拓扑情况设置，并部署到数据接收设备中的。
5)、协议模型，为生成协议的模板，保存在数据接收设备中。某协议的协议模型是对采用该协议的设备在处理数据时采用的方法或规则的抽象。所述数据接收设备可以对某协议的协议模型进行实例化，得到具体的协议。可选的，在通过软件实现协议模型和协议时，协议模型可以为类，而具体的协议为对象。
为了更加清晰的描述本发明实施例的技术方案，下面结合附图，对本发明实施例进行具体说明。
图1示出了本发明实施例的一种可能的数据传输系统的架构，在该数据传输系统中，包括：数据接收设备101、至少一个物联网设备102(如图中所示的物联网设备102-a、物联网设备102-b)。
每个物联网设备102，用于生成或采集数据，并将数据传输给数据接收设备101。其中，在每个物联网设备102生成或采集到待发送的数据后，需要通过各自采用的协议，将数据封装为数据报文，从而实现数据的传输。
数据接收设备101，连接数据传输系统中的至少一个物联网设备102，并接收每个物联网设备102发送的数据报文，并通过相应的协议对接收的数据报文进行解封装，得到相应的数据。其中，数据接收设备101中包含多个输入端口，每个输入端口可以连接一个物联网设备102，这样，数据接收设备101可以通过输入端口接收物联网设备102的数据报文。
例1，采用S7协议的物联网设备102-a连接数据接收设备101的输入端口Port1，采用OPC协议的物联网设备102-b连接数据接收设备101的输入端口Port2。
在上述场景中，那么物联网设备102-a在存在待发送的数据1后，通过S7协议，将该待发送的数据Data1封装为S7协议的数据报文，并将该S7协议的数据报文发送给数据接收设备101；而物联网设备102-b在存在待发送的数据Data1后，通过OPC协议，将该待发送的数据封装为OPC协议的数据报文并将该S7协议的数据报文发送给数据接收设备101。
数据接收设备101通过Port1接收物联网设备102-a发送的该S7协议的数据报文，并通过S7协议，对该S7协议的数据报文进行解封装，得到物联网设备102-a的数据Data1；数据接收设备101通过Port2接收物联网设备102-b发送的该OPC协议的数据报文，并通过OPC协议，对该OPC协议的数据报文进行解封装，得到物联网设备102-b的数据Data2。
可选的，该数据传输系统中还包括服务设备103，数据接收设备101得到物联网设备发送的数据后，还可以将得到的数据发送给该服务设备103。当然，所述数据接收设备101也 需要确定服务设备103采用的协议，并通过确定的协议，将得到的数据封装为数据报文，并将封装好的数据报文发送给该服务设备103。
继续以例1为例，在数据接收设备101确定服务设备103采用TCP/IP的情况下，在数据接收设备101得到Data1和Data2后，可以将Data1和Data2通过TCP/IP封装为TCP/IP的数据报文，并将封装后的TCP/IP的数据报文发送给服务设备103。
参阅图2所示，本发明实施例提供了一种数据传输方法，该方法适用于如图1所示的数据传输系统中，本方法涉及的数据接收设备101可以为该数据传输系统中的数据接收设备101。下面，以数据接收设备101执行该方法为例，对该方法的流程加以说明。图2所示的方法包括如下步骤：
步骤201：数据接收设备101获取连接目标输入端口的目标物联网设备102采用的目标协议的信息，该目标输入端口为该数据接收设备101的一个输入端口。
可选的，该目标协议的信息为该目标协议的标识、语义描述信息等唯一可以表示该目标协议的信息。
可选的，该数据接收设备101可以通过以下几种实现方式，执行步骤201：
第一种实现方式：该数据接收设备101可以通过用户输入的指令，得到连接该目标输入端口的目标物联网设备102采用的该目标协议的信息；
第二种实现方式：该数据接收设备101可以获取服务设备103发送的连接该目标输入端口的目标物联网设备102采用的该目标协议的信息；
第三种实现方式：该数据接收设备101获取连接模型，其中，该连接模型中包含连接该数据接收设备101每个输入端口的物联网设备102采用的协议的信息；该数据接收设备101在该连接模型中，获取连接该目标输入端口的目标物联网设备102采用的该目标协议的信息。
由于该连接模型中包含连接该数据接收设备101每个输入端口的物联网设备102采用的协议的信息，因此，该数据接收设备101在获取自身多个输入端口中任一个输入端口的连接的物联网设备102采用的协议的信息时，均可以采用上述第三种实现方式。
通过前序中对连接模型的描述可知，连接模型可以为用户根据实际物联网现场的网络拓扑情况设置，并部署到数据接收设备101中的。且该连接模型不仅可以包含连接数据接收设备101每个输入端口的物联网设备102采用的协议的信息，还可以包含：每个输入端口连接的物联网设备102的设备信息(例如：设备标识、IP地址等)，即该连接模型还规定了每个输入端口与连接该输入端口的物联网设备102的设备信息的对应关系。
因此，为了保证数据接收设备101可以根据该连接模型，准确地确定每个输入端口连接的物联网设备102采用的协议，因此，该数据接收设备101在获取到该连接模型之后，在执 行步骤201之前，该数据接收设备101对该连接模型的准确性或可实施性进行验证。
例如，该连接模型中规定了数据接收设备101的输入端口Port3，连接采用S7协议的物联网设备102，且该物联网设备102的IP地址为XXX.XXX.XXXX，那么该数据接收设备101可以通过Port3，发送一个目的地址为XXX.XXX.XXXX的通过S7协议封装的验证请求，若该数据接收设备101接收到该物联网设备102返回的验证响应后，说明验证成功，否则验证失败。
通过设置该连接模型，在物联网重新布网或更改现场网络环境的情况下，无需物联网管理员对物联网中的每个数据接收设备101调整或配置需要使用的协议，数据接收设备101即可得到物联网的网络拓扑情况，以及连接的每个物联网设备102使用的协议情况，因此可以降低人力成本，并提高物联网布网效率。
步骤202：该数据接收设备101在多个协议中，确定该目标协议的信息所对应的该目标协议。
可选的，该数据接收设备101可以通过以下步骤，执行步骤202：
该数据接收设备101根据该目标协议的信息，在预设的该多个协议的协议模型中确定目标协议模型，其中，任一协议的协议模型为生成该任一协议的模板；
该数据接收设备101对该目标协议模型进行实例化，得到该目标协议。
可选的，该数据接收设备101在保存多种协议的协议模型时，也相应的保存了每个协议模型对应的协议的信息，即该数据接收设备101保存了多个协议模型和协议的信息的对应关系，这样，该数据接收设备101可以直接通过上述对应关系，准确地得到该目标协议的信息所对应的所述目标协议模型。
通过前序中对协议模型的描述可知，该目标协议模型为对采用该目标协议的设备在处理数据时采用的方法或规则的抽象。因此，该数据接收设备101需要对该目标协议模型进行实例化，才可以得到该目标协议。
可选的，该目标协议可以为以下任意一项：TCP/IP、OPC协议、OPC UA协议、S7协议、Modbus协议等。
可选的，该数据接收设备101中存储有多种协议的协议模型，例如，TCP/IP模型、OPC协议模型、OPC UA协议模型、S7协议模型、Modbus协议模型等。这样，该数据接收设备101可以在获取到多种不同的协议的信息的情况下，依然可以确定每种协议的协议模型，从而得到每种协议，提高该数据接收设备101确定具体协议的效率。
另外，可以将多种协议模型存储在该数据接收设备101中，便于该数据接收设备101对存储的多种协议模型进行添加、修改或删除等管理。
步骤203：该数据接收设备101根据该目标协议，对通过该目标输入端口接收的第一数据报文进行解封装，得到数据，该第一数据报文为该目标物联网设备102发送的。
通过步骤203，该数据结束设备可以得到该目标物联网设备102发送的数据。
可选的，在数据接收系统中还包括服务设备103的情况下，在步骤203之后，所述方法还包括：
该数据接收设备101根据服务设备103使用的协议，对该数据进行封装，得到第二数据报文；
该数据接收设备101将该第二数据报文发送给该服务设备103。
可选的，上述连接模型中还包含该数据接收设备101输出端口连接的服务设备103采用的协议的信息。因此，该数据接收设备101在根据服务设备103使用的协议，对该数据进行封装之前，还包括：
通过该服务设备103采用的协议的信息，确定该服务设备103使用的协议。其中，在本步骤中，具体的确定过程可以参见上述步骤202中确定该目标协议的过程，此处不再赘述。
需要说明的是，该数据接收设备101可以采用上述方法，确定连接每个输入端口的物联网设备102采用的目标协议，进而在通过每个输入端口接收到数据报文后，可以根据相应的协议，对接收的数据报文进行解封装，从而得到每个物联网设备102发送的数据。
采用本发明实施例提供的数据传输方法，数据接收设备获取连接自身的目标输入端口的目标物联网设备采用的目标协议的信息后，确定该目标协议，并根据所述目标协议，对该目标物联网设备通过该目标输入端口发送的第一数据报文进行解封装，得到数据。在该方案中，数据接收设备无需预先为目标物联网设备配置目标协议，而是可以自适应地根据目标物联网设备采用的目标协议的信息确定目标协议，因此，通过该方案，可以提高数据接收设备中协议的使用灵活性，从而可以降低数据接收设备维护多个协议的复杂度。
基于以上实施例，本发明实施例还提供了一种对上述方法实施例涉及到的数据接收设备的一种可选的实现方式，参阅图3所示，该数据接收设备101可以包括：获取模块301、处理模块302以及通信模块303，其中，

可选的，该至少一个处理器402在该数据接收设备在多个协议中，确定该目标协议的信息所对应的该目标协议时，具体用于：
根据该目标协议的信息，在预设的该多个协议的协议模型中确定目标协议模型，其中，任一协议的协议模型为生成该任一协议的模板；
对该目标协议模型进行实例化，得到该目标协议。
可选的，该至少一个处理器402，还用于：
在得到该数据之后，根据服务设备103使用的协议，对该数据进行封装，得到第二数据报文；
通过该至少一个端口中的输出端口，将该第二数据报文发送给该服务设备103。
可选的，该至少一个存储器401，用于存储计算机程序。具体地，该程序可以包括程序代码，该程序代码包括计算机操作指令。该至少一个存储器401可能包含至少一个随机存取存储器(Random Access Memory，RAM)，也可能还包括至少一个非易失性存储器(non-volatile memory)，例如是至少一个磁盘。其中至少一个处理器402调用至少一个存储器401中存储的计算机程序，可以实现上述功能，从而实现如图2所示的数据传输方法。
本发明实施例提供了一种数据接收设备，该数据接收设备获取连接自身的目标输入端口的目标物联网设备采用的目标协议的信息后，确定该目标协议，并根据所述目标协议，对该目标物联网设备通过该目标输入端口发送的第一数据报文进行解封装，得到数据。在该方案中，数据接收设备无需预先为目标物联网设备配置目标协议，而是可以自适应地根据目标物联网设备采用的目标协议的信息确定目标协议，因此，通过该方案，可以提高数据接收设备中协议的使用灵活性，从而可以降低数据接收设备维护多个协议的复杂度。
本发明实施例还提供了一种计算机可读介质，该计算机可读介质上存储用于使一机器执行如本文所述的数据传输方法的计算机指令。具体地，可以提供配有该计算机可读介质的系统或者装置，在该计算机可读介质上存储着实现上述实施例中任一实施例的功能的软件程序代码，且使该系统或者装置的计算机(或中央处理器(Central Processing Unit，CPU)或微处理器(Micro Processor Unit，MPU))读出并执行存储在存储介质中的程序代码。
在这种情况下，从存储介质读取的程序代码本身可实现上述实施例中任何一项实施例的功能，因此程序代码和存储程序代码的存储介质构成了本发明实施例的一部分。
用于提供程序代码的存储介质实施例包括软盘、硬盘、磁光盘、光盘(如只读光盘驱动器(Compact Disc Read-Only Memory，CD-ROM)、可录光盘(Compact Disk-Recordable，CD-R)、可擦写光盘(Compact Disk-ReWritable，CD-RW)、数字视盘(Digital Video Disc-Read Only Memory，DVD-ROM)、数字多功能光盘随机存储器(Digital Versatile Disc-Random Access Memory，DVD-RAM)、可重写型数字多功能光盘(Digital Versatile Disc±ReWritable，DVD±RW)等)、磁带、非易失性存储卡和只读存储器(Read-Only Memory，ROM)。可选择地，可以由通信网络从服务器计算机上下载程序代码。
此外，应该清楚的是，不仅可以通过执行计算机所读出的程序代码，而且可以通过基于程序代码的指令使计算机上操作的操作系统等来完成部分或者全部的实际操作，从而实现上述实施例中任意一项实施例的功能。
此外，可以理解的是，将由存储介质读出的程序代码写到插入计算机内的扩展板中所设置的存储器中或者写到与计算机相连接的扩展单元中设置的存储器中，随后基于程序代码的 指令使安装在扩展板或者扩展单元上的CPU等来执行部分和全部实际操作，从而实现上述实施例中任一实施例的功能。
需要说明的是，上述各流程和各系统结构图中不是所有的步骤和模块都是必须的，可以根据实际的需要忽略某些步骤或模块。各步骤的执行顺序不是固定的，可以根据需要进行调整。上述各实施例中描述的系统结构可以是物理结构，也可以是逻辑结构，即，有些模块可能由同一物理实体实现，或者，有些模块可能分由至少两个物理实体实现，或者，可以由至少两个独立设备中的某些部件共同实现。
以上各实施例中，硬件单元可以通过机械方式或电气方式实现。例如，一个硬件单元可以包括永久性专用的电路或逻辑(如专门的处理器，现场可编程门阵列(Field-Programmable Gate Array，FPGA)或专用集成电路(Application Specific Intergrated Circuits，ASIC)等)来完成相应操作。硬件单元还可以包括可编程逻辑或电路(如通用处理器或其它可编程处理器)，可以由软件进行临时的设置以完成相应操作。具体的实现方式(机械方式、或专用的永久性电路、或者临时设置的电路)可以基于成本和时间上的考虑来确定。
上文通过附图和优选实施例对本发明实施例进行了详细展示和说明，然而本发明实施例不限于这些已揭示的实施例，基与上述实施例本领域技术人员可以知晓，可以组合上述不同实施例中的代码审核手段得到本发明更多的实施例，这些实施例也在本发明实施例的保护范围之内。
