具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
本申请提供的通信模块间通信方法，可以应用于如图1所示的应用环境中，如图1所示，通讯设备包括多个通信模块，多个通信模块之间采用串口通信，本申请提供的通信模块间通信方法具体是应用在第一通信模块中，该第一通信模块是通讯设备包括的多个通信模块中的任一个。通讯设备可以是直放站。
本申请实施例提供的通信模块间通信方法、装置、计算机设备和可读存储介质，旨在解决传统技术中，通讯设备中的多个通信模块之间采用串口通信的方式进行通信时，通信速率慢的技术问题。下面将通过实施例并结合附图具体地对本申请的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面这几个具体地实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。
需要说明的是，本申请实施例提供的通信模块间通信方法，其执行主体可以是通信模块间通信装置，该通信模块间通信装置可以通过软件、硬件或者软硬件结合的方式实现成为第一通信模块的部分或者全部。下述方法实施例中，均以执行主体是第一通信模块为例来进行说明。
请参考图2，其示出了本申请实施例提供的一种通信模块间通信方法的流程图，如图2所示，本实施例通信模块间通信方法可以包括以下步骤：
步骤S100，获取通信数据。
第一通信模块获取的通信数据是应用层发送的串口数据。
传统技术中，第一通信模块获取到应用层发送的串口数据后，直接将该串口数据通过串口发送至第二通信模块。由于串口数据没有开始和结束符，串口传输时，可能会将该串口数据拆分，分多次发送至第二通信模块，由此造成第一通信模块与第二通信模块之间传输速率慢。
步骤S200，将通信数据按照以太网数据的封装格式进行封装，得到封装后的数据。
本实施例中，第一通信模块获取通信数据，并将该通信数据按照以太网数据的封装格式进行封装，具体是将通信数据按照以太网帧格式进行封装，对该通信数据添加对应的包头信息和包尾信息，得到封装后的数据。
以太网帧格式有多种，本实施例中，对通信数据添加的包头信息和包尾信息随选用的以太网帧格式的不同而不同。例如，以太网常用帧格式有Ethernet II及IEEE 802.3格式，其中，Ethernet II中包含一个Type字段，Type字段描述了以太网首部后面所跟数据包的类型，例如，Type为0x8000时为IP协议包，Type为8060时为ARP协议包；而IEEE 802.3格式中，此位置是长度字段。本实施例对第一通信模块采用的封装格式不做具体限制。
步骤S300，通过第一通信模块的串口将封装后的数据发送至多个通信模块中的第二通信模块。
其中，第一通信模块与第二通信模块处于同一网段，以确保第二通信模块能够识别第一通信模块发送的封装后的数据。
本实施例中，第一通信模块将通信数据按照以太网数据的封装格式进行封装，得到封装后的数据后，通过第一通信模块的串口将封装后的数据发送至通讯设备包括的多个通信模块中的第二通信模块，由此，第一通信模块和第二通信模块之间传输的封装后的数据是以太网数据，串口传输时，会根据封装后的数据的包头信息和包尾信息，发送完整数据包。
本实施例中，通讯设备包括的多个通信模块之间采用串口通信，通信模块间的连接结构比较简单，避免了多个通信模块之间采用以太网连接造成的通信线较多，网口体积比较大，影响设备小型化的问题。
本实施例通讯设备包括的多个通信模块之间采用串口通信，多个通信模块中的第一通信模块获取通信数据；将通信数据按照以太网数据的封装格式进行封装，得到封装后的数据；通过第一通信模块的串口将封装后的数据发送至多个通信模块中的第二通信模块，第一通信模块与第二通信模块处于同一网段；由此，本实施例第一通信模块与第二通信模块之间传输的数据是按照以太网数据的封装格式封装后的，避免了传统技术中，第一通信模块与第二通信模块之间传输的是串口数据，由于串口数据没有开始和结束符，串口传输时可能会将一个完整的串口数据包分多次发送，由此造成的传输速率慢的问题。本实施例提升了第一通信模块与第二通信模块之间的通信速率。
图3为另一个实施例提供的通信模块间通信方法的流程示意图。在上述图2所示实施例的基础上，本实施例第一通信模块中设置有虚拟网络设备，本实施例步骤S100包括：
步骤S110，通过虚拟网络设备接收应用层传递的通信数据。
本实施例中，通讯设备包括的多个通信模块分别创建有对应的虚拟网络设备，且各虚拟网络设备的IP地址均处于同一网段，以确保多个通信模块之间可以基于按照以太网数据的封装格式封装后的数据进行通信。
第一通信模块通过虚拟网络设备接收应用层传递的通信数据，具体地，第一通信模块监测虚拟网络设备虚拟网口的数据，从虚拟网口获取通信数据，该通信数据是应用层传递至虚拟网络设备的；第一通信模块获取通信数据后，将通信数据按照以太网数据的封装格式进行封装，得到封装后的数据；通过第一通信模块的串口将封装后的数据发送至多个通信模块中的第二通信模块。由此，提升了第一通信模块与第二通信模块之间的通信速率。
在另一个实施例中，基于上述图2所示的实施例，参见图4，图4为本实施 例中步骤S300的细化步骤示意图。本实施例通信模块间通信方法中，步骤S300包括步骤S310和步骤S320，具体地：
步骤S310，将封装后的数据存入发送缓存。
由于通信模块将封装后的数据写入串口的速率快，而串口传输封装后的数据的速率较慢，容易造成通信模块写入串口的封装后的数据，来不及被串口发送所导致的数据丢失的问题。
本实施例中，第一通信模块设置有发送缓存，第一通信模块获取通信数据，将通信数据按照以太网数据的封装格式进行封装，得到封装后的数据后，将封装后的数据存入发送缓存。
步骤S320，从发送缓存中读取封装后的数据，并通过第一通信模块的串口将封装后的数据发送至多个通信模块中的第二通信模块。
第一通信模块将封装后的数据存入发送缓存后，再从发送缓存中读取封装后的数据，并通过第一通信模块的串口将封装后的数据发送至多个通信模块中的第二通信模块，由此，避免了封装后的数据的丢失，提升了通信模块间的通信传输的准确性。
图5为另一个实施例提供的通信模块间通信方法的流程示意图。在上述图2所示实施例的基础上，本实施例通信模块间通信方法还包括：
步骤S410，从第一通信模块的串口读取目标数据。
目标数据是按照以太网数据的封装格式进行封装得到的。
在第一通信模块作为接收端时，通讯设备包括的多个通信模块中的其它通信模块作为发送端，发送端首先获取通信数据，该通信数据可以是应用层发送的串口数据，然后将通信数据按照以太网数据的封装格式进行封装，得到封装 后的数据，再通过当前发送端通信模块的串口将封装后的数据发送至第一通信模块的串口。
第一通信模块监测串口的数据，从第一通信模块的串口读取发送端发送的封装后的数据，即目标数据。
步骤S420，对目标数据进行解封装，得到解封装后的数据。
第一通信模块对目标数据的封装格式进行解封装，具体是对目标数据的包头信息和包尾信息进行解封装，得到解封装后的串口数据，供应用层获取该串口数据，并对该串口数据进行处理。
本实施例中，对于应用层来说，基于各通信模块的串口物理连接实现了应用层的网络通信。物理层使用串口数据通信，应用层使用以太网数据进行处理，通过通信模块间简单的串口连接，应用层可以灵活地使用TCP、UDP、FTP、TFTP等网络协议来实现不同的业务需求，且应用层不用处理底层具体的数据包发送问题，提高了应用层软件的开发效率。
在另一个实施例中，基于上述图5所示的实施例，参见图6，图6为本实施例中步骤S420的细化步骤示意图。本实施例通信模块间通信方法中，步骤S420包括步骤S421和步骤S422，具体地：
步骤S421，将目标数据存入接收缓存。
本实施例中，作为一种实施方式，第一通信模块设置有接收缓存，第一通信模块从第一通信模块的串口读取目标数据后，将目标数据存入接收缓存。
步骤S422，从接收缓存中读取目标数据，并将目标数据包括的包头信息和包尾信息解除，得到解封装后的数据。
第一通信模块从接收缓存中读取存入的目标数据，并将目标数据包括的包头信息和包尾信息解除，得到解封装后的串口数据，供应用层获取该串口数据， 并对该串口数据进行处理。由此，避免了在数据传输过程中，由于第一通信模块获取目标数据的速率与应用层获取解封装后的数据的速率不一致，导致的数据丢失的问题，确保了数据传输的准确性。
图7为另一个实施例提供的通信模块间通信方法的流程示意图。在上述图6所示实施例的基础上，本实施例第一通信模块中设置有虚拟网络设备，本实施例通信模块间通信方法还包括：
步骤S430，通过虚拟网络设备将解封装后的数据传递至应用层。
本实施例中，作为一种实施方式，第一通信模块作为接收端与通讯设备包括的多个通信模块中的其它通信模块进行通信时，其它通信模块作为发送端，发送端的应用层软件发送通信数据到发送端的虚拟网络设备，发送端从该虚拟网络设备读取通信数据，发送端将通信数据按照以太网数据的封装格式进行封装，得到封装后的数据，并将封装后的数据存入发送缓存中；发送端从发送缓存中读取封装后的数据，并通过发送端的串口将封装后的数据发送至第一通信模块。进一步地，第一通信模块，即接收端的串口接收到目标数据，即该封装后的数据后，第一通信模块将目标数据存入接收缓存，并从接收缓存中读取目标数据，并将目标数据包括的包头信息和包尾信息解除，得到解封装后的串口数据，发送该解封装后的串口数据到第一通信模块的虚拟网络设备，应用层从第一通信模块的虚拟网络设备的端口读取该解封装后的串口数据进行处理。可以理解的是，通讯设备包括的多个通信模块中，任一个通信模块既可以作为发送端，也可以作为接收端。
由此，通讯设备的各通信模块之间采用串口连接，通信模块将串口数据与以太网数据互相转换，物理层使用串口数据通信，应用层使用以太网数据进行处理，提高了应用层软件的开发效率，提升了通讯设备中各通信模块之间的通 信速率。
参见图8，图8为另一个实施例提供的通信模块间通信方法的流程示意图。在上述图3所示实施例的基础上，本实施例通信模块间通信方法还包括：
步骤S500，基于第一通信模块当前的通信模式，设置第一通信模块包括的虚拟网络设备的IP地址。
IP地址的网段和第二通信模块所对应的网段相同，通信模式包括主机模式或从机模式。
本实施例中，第一通信模块根据第一通信模块的拨码开关的状态，识别第一通信模块当前的通信模式为主机模式或从机模式；具体地，通讯设备包括的各通信模块均设置有拨码开关，拨码开关的不同状态表示当前通信模块不同的通信模式，例如，表示主机模式、从机1模式、从机2模式，等等。
进一步地，参见图9，图9为本实施例中步骤S500的细化步骤示意图，如图9所示，本实施例步骤S500包括步骤S510和步骤S520，具体地：
步骤S510，若第一通信模块当前的通信模式为主机模式，则创建虚拟网桥，并设置虚拟网桥的IP地址。
虚拟网桥用于虚拟网络设备与第一通信模块的对外连接网口连接。
步骤S520，将虚拟网桥的IP地址设置为虚拟网络设备的IP地址。
为了更清楚地说明本实施例的实施方式，请结合图1，假设本实施例通讯设备包括如图1所示的通信模块1、通信模块2以及通信模块3，通信模块1作为主机模式，其拨码开关设置为00；通信模块2作为从机1模式，拨码开关设置为01，通信模块3作为从机2模式，拨码开关设置为11，本实施例第一通信模块则为图1所示的通信模块1。
如图1所示，每个通信模块都包括两个串口：串口1和串口2。通信模块1的MCU与串口1和串口2连接，通信模块2的MCU与串口1连接，通信模块3的MCU与串口2连接，三个通信模块的串口1和串口2分别通过端子连接。由此，通信模块1可通过串口1与通信模块2通信、通过串口2与通信模块3通信，通信模块2的串口2用来直通通信模块1和通信模块3之间的串口数据。
各通信模块创建对应的虚拟网络设备，第一通信模块根据第一通信模块的拨码开关的状态，识别第一通信模块当前的通信模式为主机模式时，通过系统命令创建网桥，并设置网桥的IP地址，例如设置为192.168.10.100，并将虚拟网桥的IP地址设置为第一通信模块的虚拟网络设备的IP地址。
进一步地，作为一种实施方式，本实施例步骤S500还包括步骤S530：
步骤S530，将虚拟网桥的IP地址设置为对外连接网口的IP地址，以供外部调测模块通过对外连接网口的IP地址，对与虚拟网桥的IP地址处于同一网段的各通信模块进行调测。
第一通信模块将虚拟网桥的IP地址设置为对外连接网口的IP地址，即将第一通信模块虚拟网络设备的虚拟网口和对外连接网口加入到网桥中。
通信模块2为从机1模式，通信模块2设置其虚拟网络设备的IP地址与网桥的IP地址同一网段，比如设置为192.168.10.101。通信模块3为从机2模式，通信模块3设置其虚拟网络设备的IP地址与网桥的IP地址同一网段，且与通信模块2的虚拟网络设备的IP地址不同，比如设置为192.168.10.102。由此，通信模块1、通信模块2以及通信模块3之间建立网络连接。
在另一个实施例中，参见图10，图10为另一个实施例中步骤S500的细化步骤示意图，如图10所示，本实施例步骤S500包括步骤S540和步骤S550，具体地：
步骤S540，若第一通信模块当前的通信模式为从机模式，则获取当前通信模式为主机模式的通信模块所对应的IP网段。
步骤S550，设置虚拟网络设备的IP地址，并将虚拟网络设备的IP地址的网段与获取到的IP网段保持一致。
请继续参见图1，若第一通信模块当前的通信模式为从机模式，即第一通信模块为图1所示的通信模块2或通信模块3，则获取当前通信模式为主机模式的通信模块所对应的IP网段，即获取通信模块1所对应的IP网段。
通信模块1完成网桥的IP地址的设置后，通信模块1的虚拟网络设备的虚拟网口和对外连接网口均归入该网桥中，即均和该网桥的IP地址相同。第一通信模块获取通信模块1的网桥IP地址，确定网段，并设置第一通信模块的虚拟网络设备的IP地址，将第一通信模块的虚拟网络设备的IP地址的网段与通信模块1的IP网段保持一致，以建立连接。
本实施例中，通讯设备的每一个通信模块均包含两个串口，每个通信模块的两个串口使用端子连接，如图1所示，每个通信模块的串口1与其它通信模块的串口1相连，每个通信模块的串口2与其它通信模块的串口2相连。通信模块之间的通信协议为主从机通信。各通信模块设置有拨码开关，各通信模块根据对应的拨码开关的状态确定通信模块当前的工作模式。工作模式包括主机模式、从机1模式、从机2模式，通信模块处于不同工作模式时，物理连接上选择与串口1和串口2是否连接，主机模式与串口1和串口2连接，从机1模式与串口1连接，从机2模式与串口2连接。由此，主机模式的通信模块的两个串口可实现分别与两个从机模式的通信模块的串口相连。
以通讯设备为直放站为例，当仅需要单频设备时，选用一个通信模块，设置拨码开关的状态为主机模式即可。当需要双频设备时，选用两个通信模块， 分别设置拨码开关的状态为主机模式和从机1模式。需要三频设备时，选用三个通信模块，分别设置拨码开关的状态为主机模式、从机1模式，从机2模式，等等。
本实施例中，对于应用层来说，虚拟网络设备的网口可看做一个普通的网口对其进行操作，例如，主机模式的通信模块1需要定时轮询从机模式的通信模块2或通信模块3的数据，由于通信模块1、通信模块2及通信模块3均处于同一网段，各通信模块设置其固定的端口作为UDP端口，通信模块1则可以与通信模块2或通信模块3之间分别建立UDP连接。通信模块1与通信模块2、通信模块1与通信模块3则可以通过UDP连接进行查询、设置等操作。进一步地，如果通信模块2或通信模块3需要从通信模块1下载文件，通信模块1搭建好FTP服务器，通信模块2或通信模块3作为FTP客户端通过虚拟网络设备建立与通信模块1的FTP连接，这样便可从通信模块1下载或者上传指定的文件。避免了传统技术中，主机和从机之间仅使用串口数据进行通信，文件传输必须通过主从通信协议，导致的传输效率慢的问题。
本实施例中，调测工具可以通过通信模块1的对外连接网口直接连接到通信模块2和通信模块3进行调测，在通讯设备生产时，传统技术中，需要通过主从通信协议进行各通信模块工作模式的转换，调测工具只能对主机进行调测，导致调测效率低，因此本申请提高了调测效率，提高了通讯设备的生产效率。
应该理解的是，虽然图2-10的流程图中的各个步骤按照箭头的指示依次显示，但是这些步骤并不是必然按照箭头指示的顺序依次执行。除非本文中有明确的说明，这些步骤的执行并没有严格的顺序限制，这些步骤可以以其它的顺序执行。而且，图2-10中的至少一部分步骤可以包括多个子步骤或者多个阶段，这些子步骤或者阶段并不必然是在同一时刻执行完成，而是可以在不同的时刻 执行，这些子步骤或者阶段的执行顺序也不必然是依次进行，而是可以与其它步骤或者其它步骤的子步骤或者阶段的至少一部分轮流或者交替地执行。
