本发明涉及塔机通信技术领域，具体地，涉及一种用于建立通信连接的方法、装置、塔机及存储介质。
塔机设备的远程控制装置由两个通信设备组成，其中一个通信设备安装在塔机设备上，可以直接有线接入塔机设备；另一个通信设备则由操作人员进行远程控制，当两个通信设备配对完成后，操作人员通过操作另一个通信设备可以实现对塔机设备的远程控制。这两个通信设备的配对关系在出厂时被固化在遥控的固定存储器里，只能按照出厂时的配对关系进行使用。

以下结合附图对本发明的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明，并不用于限制本发明。
为了便于更好地理解本发明的技术方案，图1是根据本发明实施例提供的用于建立通信连接的方法的流程图之一，如图1所示，本发明提供一种用于建立通信连接的方法，包括以下步骤：
步骤101，第一通信设备获取与第一通信设备通信的塔机设备的第一标识信息；
步骤102，第一通信设备接收第二通信设备发送的连接请求，连接请求包含第二标识信息；
步骤103，第一通信设备将第一标识信息与第二标识信息进行比对；
步骤104，在第一标识信息与第二标识信息一致的情况下，第一通信设备确定第一通信设备与第二通信设备配对成功；
步骤105，第一通信设备确认第一通信设备的连接状态；
步骤106，在连接状态为未连接的情况下，第一通信设备与第二通信设备建立通信连接。
图2是根据本发明实施例提供的第一通信设备与第二通信设备的连接示意图，可参见图2，第一通信设备可以直接设置在塔机上，第一通信设备与塔机可以通过有线连接进行通信，具体地，第一通信设备可以与塔机监控器有线连接，这样第一通信设备可以自动获取塔机的第一标识信息，即塔机的唯一标识。有线通信的方式可以是CAN总线(Controller Area Network，控制器局域网络)、RS-485、RS-232、PROFIBUS(过程现场总线)和ethernet(以太网)等。
第二通信设备可以为塔机的远程控制设备，即第二通信设备可以为遥控发射器，而第一通信设备可以为遥控接收器，遥控发射器与遥控接收器无线连接。每个塔机监控器具有唯一的ID(Identity Document，身份标识号)，可以是设备硬件ID，可以是物联网卡卡号，也可以是用户自定义的具有区别性的编码。因此只要第二通信设备和第一通信设备都获取到了塔机的ID，那么就可以用这个ID来作为配对的依据。塔机监控器的ID就可以理解是塔机的ID，塔机的ID可 以理解是塔机的标识信息。
在一实施例中，塔机遥控配对方法的流程如下：操作者获取当前塔机监控器的唯一ID；操作者将当前塔机监控器的唯一ID输入第二通信设备；第一通信设备与塔机监控器建立连接后自动获取塔机监控器的唯一ID；当第一通信设备获取的ID与第二通信设备接收输入的ID一致时，完成配对；第一通信设备只接收配对成功的第二通信设备发送的信息或控制指令。
操作者通过查看塔机监控器的显示屏可以获取到塔机监控器的ID，也可以事先将ID贴在塔机下方，方便操作者不用上塔也能获取到塔机监控器的ID。获取到ID后，如果第二通信设备本身带有按键和屏幕的，可以通过按键输入ID；如果没有按键和显示屏的，也可以通过拨码开关来输入ID，成本都比现有方案中的移动存储器要低。而第一通信设备只要与塔机监控器建立连接，就可以通过软件通信的方式获取到塔机监控器的ID。当第二通信设备和第一通信设备都获取到了塔机监控器的ID，那么第一通信设备就可以只接收包含监控器ID的无线信息，从而实现遥控发射器(第二通信设备)和遥控接收器(第一通信设备)的配对。
第二通信设备在实现对塔机的远程控制之前，需要与塔机上的第一通信设备建立通信连接。具体地，第一通信设备会比对自身获取的第一标识信息与第二通信设备发送的连接请求中的第二标识信息，只有在第一标识信息与第二标识信息比对一致的情况下，第一通信设备与第二通信设备才配对成功，然后在配对成功的情况下，当第一通信设备的连接状态为未连接，此时，第一通信设备响应于第二通信设备的连接请求，与第二通信设备建立通信连接。
这样，相比现有技术中固定存储配对关系，在本发明实施例中，之前未配对的第二通信设备与塔机上的第一通信设备在出厂后可以重新进行配对；可以通过塔机的唯一标识来实现第二通信设备和第一通信设备的配对关系；使用和维护都更方便。相比使用移动存储配对关系的接收，由于需要增加移动存储器，增加了成本，移动存储器是小物品，容易遗失，造成财产损失；本发明实施例中，成本更低，且没有易丢失的器件，不会带来财产损失。
不同的第二通信设备均可以实现灵活地与第一通信设备通信，而且只有在第一通信设备的连接状态为未连接的情况下，第一通信设备才会与第二通信设备建立通信连接，这样可以避免多个不同的第二通信设备同时与第一通信设备建立通信。不同塔机上的第一通信设备也可以实现灵活地与第二通信设备通信，通过第二通信设备与多个第一通信设备之间的灵活配对，操作人员只需持有一台第二通信设备即可分时控制多台塔机，能够实现灵活切换控制不同塔机，提高了资源的利用率。
在一实施例中，为了防止不同遥控发射器(即第二通信设备)同时与接收器(即第一通信设备)建立通信，可以采用以下方法：(1)每个遥控发射器本身包含一个唯一地址，以此来区别不同的遥控发射器；(2)采取先到独占策略，也就是哪个遥控发射器先申请控制权，哪个遥控发射器就可以一直与接收器进行通信，其他同样拥有塔机监控器ID的遥控发射器也无法进行抢占，除非当前通信的遥控发射器释放控制权，后面的遥控发射器才能申请控制权并进行通信。
在一实施例中，在第一通信设备与第二通信设备建立通信连接之后，第一通信设备向第二通信设备发送连接成功消息，之后第二通信设备可以向第一通信设备发送对于塔机的控制指令，实现了塔机的远程控制。
在一实施例中，在第一标识信息与第二标识信息比对不一致的情况下，第 一通信设备向第二通信设备发送配对失败消息；在连接状态为已连接的情况下，第一通信设备向第二通信设备发送连接失败消息。
在一实施例中，在配对成功的情况下，第二通信设备保存第二标识信息，其中第二标识信息与塔机设备一一对应，第二标识信息是塔机设备的唯一标识；第二通信设备选定保存后的一个或多个第二标识信息中的目标标识信息，其中目标标识信息与多个塔机设备中的目标塔机设备对应；在目标塔机设备对应的第一通信设备的连接状态为未连接的情况下，第二通信设备与目标塔机设备对应的第一通信设备建立通信连接。可以理解地，遥控器发射器可以保存多个塔机监控器的ID，这样只需要通过按键切换ID，就能非常方便地切换对不同塔机的控制。
图3是根据本发明实施例提供的用于建立通信连接的方法的流程图之二，如图3所示，本发明提供一种用于建立通信连接的方法，包括以下步骤：
步骤301，第一通信设备接收进入配对模式指令；
步骤302，第一通信设备确认第一通信设备的连接状态；
步骤303，在连接状态为未连接的情况下，第一通信设备响应于进入配对模式指令而进入配对模式；以及
步骤304，第一通信设备与进入配对模式的第二通信设备建立通信连接。
遥控发射器(即第二通信设备)与接收器(即第一通信设备)可以在软件上设置一个配对模式，可以通过按键或者屏幕操作来进入配对模式。在配对模式下，没有配对过的遥控发射器和接收器也可以进行相互通信。可以理解地，在一实施例中，当第一通信设备的连接状态为未连接，且第一通信设备与第二通信设备同时进入配对模式的情况下，第一通信设备与第二通信设备建立通信连接。
在一实施例中，在第一通信设备与进入配对模式的第二通信设备建立通信连接之后，第一通信设备接收并保存第二通信设备发送的第二身份信息；第一通信设备向第二通信设备发送配对成功消息。在一实施例中，在第一通信设备与进入配对模式的第二通信设备建立通信连接之后，第二通信设备接收并保存第一通信设备发送的第一身份信息；第二通信设备接收第一通信设备发送的配对成功消息。其中，第一身份信息包括第一通信设备的通信地址和/或身份标识号，第二身份信息包括第二通信设备的通信地址和/或身份标识号。也就是，自动保存对方的通信地址或者ID，以实现互相配对的目的。
在一实施例中，退出配对模式，且第一通信设备与第二通信设备断开连接之后，第一通信设备可以接收第二通信设备发送的连接请求，连接请求包含第二身份信息；第一通信设备将接收的第二身份信息与保存的第二身份信息进行比对；第一通信设备确认第一通信设备的连接状态；在接收的第二身份信息与保存的第二身份信息比对一致，且连接状态为未连接的情况下，第一通信设备与第二通信设备建立通信连接。也就是，退出配对模式后，只有遥控接收器保存过遥控发射器的通信地址或者ID，遥控发射器才能与遥控接收器进行通信连接，进而对塔机进行远程控制。
本发明实施例提供一种用于建立通信连接的装置，包括：
第一通信设备，被配置成执行上述的用于建立通信连接的方法。
具体地，用于建立通信连接的装置还包括：

接收第一通信设备发送的配对成功消息。
本发明实施例提供一种塔机，包括上述实施例中任一实施例的用于建立通信连接的装置。
本发明实施例提供一种机器可读存储介质，该机器可读存储介质上存储有指令，该指令用于使得机器执行上述实施例中任一实施例的用于建立通信连接的方法。
下面以另外一些实施例来对工程机械(例如塔机)的建立通信连接的方法来进行详细说明。
图4为本发明用于建立通信连接的方法一实施例的流程示意图。参照图4，在本发明实施例中，用于建立通信连接的方法包括以下步骤：
S10：第二通信设备接收多个工程机械上设置的多个第一通信设备发送的广播消息及特征信息，其中，广播消息包括第一通信设备的连接状态信息。
可以理解的是，本发明实施例的执行主体为第二通信设备。现有技术中通常需要为每个工程机械分别配备一个第一通信设备和一个第二通信设备，第一通信设备和第二通信设备固定配对。以工程机械是塔机为例，在塔群作业时，要实现各塔机的控制，需要在各塔机上均接入第一通信设备，并且配备多个与第一通信设备匹配的第二通信设备，导致通信设备管理难度大，寻找和更换第二通信设备时费时费力。而且当某塔机对应的第二通信设备丢失或故障，其他第二通信设备即便空闲也无法用来对该塔机进行操作，只能等待厂家处理，既耽误了施工进度，又造成了资源的浪费。
本发明实施例通过第二通信设备与多个第一通信设备灵活配对，只需要一个第二通信设备即可实现对多个第一通信设备的分时控制，在操作人员需要对其他塔机进行控制时，无需更换第二通信设备，避免了资源浪费，也提高了施工建设的效率。
在具体实现中，为了实现对塔机的远程控制，塔机上会设置第一通信设备，第一通信设备向第二通信设备发送广播消息和特征信息，由操作人员控制的第二通信设备根据接收到的信息与符合条件的第一通信设备建立自动连接。
需要说明的是，第一通信设备的连接状态信息可以是有线连接状态或无线连接状态。当工程机械是塔机时，连接状态信息为无线连接状态。
图5为本发明实施例的第二通信设备和第一通信设备的结构示意图。一并参照图4和图5，第二通信设备由操作人员掌握，第一通信设备安装在塔机上，二者通过无线技术进行通讯。第二通信设备主要包括输入单元、显示单元、控制 单元以及无线通讯单元，操作人员可以通过显示单元观察到塔机的参数、运行状态以及无线连接状态等信息，通过操作输入单元可以控制塔机进行起升、回转、调幅等动作。第一通信设备主要包括无线通讯单元、控制单元以及总线通讯单元，第一通信设备相当于第二通信设备和塔机之间的桥梁，其中的无线通讯单元用于与第二通信设备进行远程通讯，总线通讯接口用于与塔机通讯。
应当理解的是，特征信息可以是信号强度、位置信息或距离等信息，本发明实施例对此不加以限制。
S20：第二通信设备根据特征信息确定第二通信设备是否进入目标工程机械的工作区域。
应当理解的是，当操作人员需要通过操作第二通信设备控制指定的工程机械时，操作人员可以在第二通信设备上根据实际工况选择手自动模式、设置目标工程机械的工作区域。
在手动模式下，操作人员可以根据第二通信设备上显示的各第一通信设备的身份信息以及特征信息，快速准确地选中要连接的第一通信设备，实现人工配对。
在自动模式下，第二通信设备根据各第一通信设备的特征信息确定是否进入目标工程机械的工作区域。
以工程机械是塔机、特征信息为第一通信设备的信号强度或位置信息为例，第二通信设备可以确定多个第一通信设备中信号强度最大或位置最近的候选第一通信设备的数量；在候选第一通信设备的数量为1的情况下，确定候选第一通信设备是否为设置在目标工程机械的设备；在候选第一通信设备为设置在目标工程机械的设备的情况下，确定第二通信设备进入目标工程机械的工作区域。
应当理解的是，如果各塔机上的第一通信设备广播至第二通信设备的信号强度或位置信息中，只有一个第一通信设备的信号强度最大或位置最近，并且该第一通信设备是目标塔机上的通信设备，则可以确定第二通信设备进入目标工程机械的工作区域。
在另一个示例中，在候选第一通信设备的数量大于1的情况下，在预设时长之后获取候选第一通信设备发送的特征信息；确定候选第一通信设备发送的特征信息的变化量；根据变化量确定第二通信设备是否进入目标工程机械的工作区域。
具体地，可以在变化量为信号强度变大或位置变近的情况下，确定变化量对应的候选第一通信设备是否为设置在目标工程机械的设备；在确定变化量对应的候选第一通信设备为设置在目标工程机械的设备的情况下，确定第二通信设备进入目标工程机械的工作区域。
应当理解的是，如果各塔机上的第一通信设备广播至第二通信设备的信号强度或位置信息中，同时存在两个或两个以上的第一通信设备的信号强度最大或位置最近，将该两个或两个以上的第一通信设备称为候选第一通信设备。在预设时长之后再次获取候选第一通信设备发送的特征信息，选择信号强度变大或位置变近的候选第一通信设备，如果该候选第一通信设备是目标塔机上的设备，则可以确定第二通信设备进入目标工程机械的工作区域。
在又一个示例中，在候选第一通信设备的数量大于1的情况下，确定多个候选第一通信设备与预设点的距离；确定与预设点的距离最近的候选第一通信设备是否为设置在目标工程机械的设备；在确定预设点的距离最近的候选第一通信设备为设置在目标工程机械的设备的情况下，确定第二通信设备进入目标工程机 械的工作区域。
应当理解的是，操作人员还可以根据塔机的使用工况在第二通信设备中设置预设点，如果各塔机上的第一通信设备广播至第二通信设备的信号强度或位置信息中，同时存在两个或两个以上的第一通信设备的信号强度最大或位置最近，将该两个或两个以上的第一通信设备称为候选第一通信设备。通过各候选第一通信设备广播的位置信息可以确定各候选第一通信设备与预设点的距离，如果与预设点的距离最近的候选第一通信设备同时也是目标塔机上的设备，则可以确定第二通信设备进入目标工程机械的工作区域。
如此，第二通信设备实现了在第一通信设备广播的特征信息相同的情况下，确定自己是否进入目标工程机械的工作区域，以便于与目标工程机械上的第一通信设备实现自动连接。
S30：第二通信设备在确定第二通信设备进入工作区域的情况下，将目标工程机械上设置的第一通信设备作为目标通信设备，并根据目标通信设备的连接状态信息确定目标通信设备的连接状态。
应当理解的是，目标通信设备的连接状态可以分为连接和未连接，当目标通信设备的连接状态是连接时，第二通信设备禁止与目标通信设备建立连接，当目标通信设备的连接状态是未连接时，第二通信设备可以与目标通信设备建立连接，如此可以有效避免目标通信设备同时被多个第二通信设备控制。
S40：第二通信设备在确定目标通信设备的连接状态为未连接的情况下，向目标通信设备发送连接请求，以与目标通信设备建立通信连接。
当第二通信设备进入了目标工程机械的工作区域，并且目标通信设备未连接的情况下，第二通信设备向目标通信设备发送连接请求，实现与目标通信设备的自动连接。
在一个示例中，广播消息还包括第一通信设备的身份信息；连接请求包括第二通信设备的身份信息、第二通信设备的连接状态信息以及目标通信设备的身份信息。
其中，身份信息可以是设备名称、地址或设备标识等信息，本发明实施例对此不加以限制。图6为本发明实施例的第二通信设备和目标通信设备配对信号流示意图，一并参照图4至图6，第二通信设备发送的连接请求中包括第二通信设备的身份信息和连接状态信息、目标通信设备的身份信息。当目标通信设备接收到连接请求，得到了第二通信设备的身份信息，则配对完成。通过在广播消息中加入第一通信设备的身份信息，以及在连接请求中加入第二通信设备的身份信息和目标通信设备的身份信息，提高了配对的准确性。
本发明实施例通过第二通信设备接收多个工程机械上设置的多个第一通信设备发送的广播消息及特征信息，其中，广播消息包括第一通信设备的连接状态信息；第二通信设备根据特征信息确定第二通信设备是否进入目标工程机械的工作区域；第二通信设备在确定第二通信设备进入工作区域的情况下，将目标工程机械上设置的第一通信设备作为目标通信设备，并根据目标通信设备的连接状态信息确定目标通信设备的连接状态；第二通信设备在确定目标通信设备的连接状态为未连接的情况下，向目标通信设备发送连接请求，以与目标通信设备建立通信连接。如此，通过第二通信设备与多个第一通信设备之间的灵活配对，操作人员只需持有一台第二通信设备即可分时控制多台工程机械，提高了资源的利用率。
图7为本发明用于建立通信连接的方法另一实施例的流程示意图。如图7所示，本发明实施例中，用于建立通信连接的方法还可以包括以下步骤：
S50：第二通信设备确定与目标通信设备的通信连接是否成功。
应当理解的是，当目标通信设备接收到第二通信设备的连接请求后，与第二通信设备建立通信连接。在一个示例中，当通信连接完成后，目标通信设备会向第二通信设备发送回执信息，第二通信设备根据回执信息确定连接是否成功。
S60：在通信连接成功的情况下，第二通信设备向目标通信设备发送响应触发信息和控制信息，以使目标通信设备根据响应触发信息响应控制信息。
在一个示例中，响应触发信息可以包括第二通信设备的身份信息和目标通信设备的身份信息，目标通信设备可以确定是否接收到第二通信设备的身份信息和目标通信设备的身份信息；在接收到第二通信设备的身份信息和目标通信设备的身份信息的情况下，响应控制信息。
图8为本发明实施例的第二通信设备和目标通信设备的数据传输信号流示意图。一并参照图7和图8，在通信连接成功后，第二通信设备与目标通信设备之间进行控制信息传输时，都会带上响应触发信息，该响应触发信息包括双方的身份信息。并且，在双方通信过程中，仅响应带有双方身份信息的消息。例如，第二通信设备只有在接收到带有双方身份信息的响应触发信息，才响应目标通信设备发送的其他信息；目标通信设备只有在接收到带有双方身份信息的响应触发信息，才响应控制信息。
在另一个示例中，响应触发信息还可以包括加密信息，目标通信设备在接收到加密信息后，对加密信息进行解密，在解密成功的情况下，响应控制信息。
进一步地，在通信连接成功的情况下，第二通信设备还可以禁止向除目标通信设备以外的其他第一通信设备发送连接请求，如此可以有效避免第二通信设备同时控制多台第一通信设备。
本发明实施例通过第二通信设备确定连接成功的情况下，向目标通信设备发送响应触发信息和控制信息，以使目标通信设备根据响应触发信息响应控制信息，实现了两个通信设备之间数据的传输。由于通信设备只会响应带自身身份信息的消息，避免了消息的错误响应导致的控制出错，提高了通信的准确率。
图9为本发明用于建立通信连接的方法又一实施例的流程示意图。如图9所示，本发明实施例中，用于建立通信连接的方法应用于工程机械，工程机械上设置有第一通信设备，该方法可以包括以下步骤：
S11：第一通信设备向第二通信设备发送广播消息，广播消息包括第一通信设备的连接状态信息。
可以理解的是，本发明实施例的执行主体为第一通信设备。为了实现与第二通信设备的配对，第一通信设备会向第二通信设备发送广播消息。
在具体实现中，第一通信设备的连接状态信息可以是有线连接状态或无线连接状态。当工程机械是塔机时，连接状态信息为无线连接状态。
S21：向第二通信设备发送特征信息，以使第二通信设备根据特征信息确定是否进入目标工程机械的工作区域。
应当理解的是，特征信息可以是信号强度、位置信息或距离等信息，本发明实施例对此不加以限制。
其中，第二通信设备根据特征信息确定第二通信设备是否进入目标工程机械的工作区域的具体方案可以参照上述实施例，在此不再赘述。
S31：接收第二通信设备发送的连接请求；
S41：响应于连接请求，与第二通信设备建立通信连接。
当第二通信设备进入了目标工程机械的工作区域，并且目标工程机械上的 第一通信设备未连接的情况下，第二通信设备向第一通信设备发送连接请求，第一通信设备实现与第二通信设备的自动连接。
进一步地，第一通信设备发送的广播消息还可以包括第一通信设备的身份信息；第二通信设备发送的连接请求可以包括第二通信设备的身份信息、第二通信设备的连接状态信息以及目标通信设备的身份信息。第一通信设备在与第二通信设备建立连接成功之后，向第二通信设备发送的数据中，也可以包括第一通信设备的身份信息以及第二通信设备的身份信息。如此，第一通信设备和第二通信设备只响应带有双方身份信息的消息即可，避免了消息的错误响应。
进一步地，在通信连接成功的情况下，第一通信设备还可以禁止与其他第二通信设备建立通信连接，如此可以有效避免第一通信设备同时被多台第二通信设备控制。
本发明实施例通过第一通信设备向第二通信设备发送广播消息，广播消息包括第一通信设备的连接状态信息；向第二通信设备发送特征信息，以使第二通信设备根据特征信息确定是否进入目标工程机械的工作区域；接收第二通信设备发送的连接请求，响应于连接请求，与第二通信设备建立通信连接。如此，实现了第二通信设备与第一通信设备之间的灵活配对，操作人员只需持有一台第二通信设备即可分时控制多台工程机械，提高了资源的利用率。
图10为本发明用于建立通信连接的方法再一实施例的流程示意图。如图10所示，本发明实施例中，用于建立通信连接的方法应用于工程机械，工程机械上设置有第一通信设备，该方法可以包括以下步骤：
S12：第一通信设备接收多个第二通信设备发送的广播消息及特征信息，其中，广播消息包括第二通信设备的连接状态信息。
可以理解的是，本发明实施例的执行主体为设置在工程机械上的第一通信设备。现有技术中通常需要为每个工程机械分别配备一个第一通信设备和一个第二通信设备，第一通信设备和第二通信设备固定配对。以工程机械是塔机为例，在塔群作业时，要实现各塔机的控制，需要在各塔机上均接入第一通信设备，并且配备多个与第一通信设备匹配的第二通信设备，导致寻找与第一通信设备配对的第二通信设备时费时费力。
本发明实施例通过第一通信设备与多个第二通信设备灵活配对，第一通信设备可以快速从众多的第二通信设备中选择一个自动匹配，也提高了施工建设的效率。
在具体实现中，为了实现与第二通信设备的自动匹配，第一通信设备接收多个第二通信设备发送的广播消息和特征信息，并根据接收到的信息与符合条件的第二通信设备建立自动连接。
S22：第一通信设备根据特征信息确定第二通信设备是否进入工程机械的工作区域。
在具体实现中，确定第二通信设备是否进入所述工程机械的工作区域的方法可以参考上述实施例，将上述实施例中的第一通信设备与第二通信设备互换即可，在此不再赘述。
S32：第一通信设备在确定第二通信设备进入工作区域的情况下，将进入工作区域的第二通信设备作为目标通信设备，并根据目标通信设备的连接状态信息确定目标通信设备的连接状态。
应当理解的是，目标通信设备的连接状态可以分为连接和未连接，当目标通信设备的连接状态是连接时，第一通信设备禁止与目标通信设备建立连接，当 目标通信设备的连接状态是未连接时，第一通信设备可以与目标通信设备建立连接，如此可以有效避免目标通信设备同时被多个第一通信设备控制。
S42：第一通信设备在确定目标通信设备的连接状态为未连接的情况下，向目标通信设备发送连接请求，以与目标通信设备建立通信连接。
当目标通信设备进入了工程机械的工作区域，并且目标通信设备未连接的情况下，第一通信设备向目标通信设备发送连接请求，实现与目标通信设备的自动连接。
本发明实施例实现了在存在多个第二通信设备时，设置在工程机械上的第一通信设备与进入工程机械的第二通信设备建立自动连接，提高了通信连接的效率。
以上结合附图详细描述了本发明的优选实施方式，但是，本发明并不限于上述实施方式中的具体细节，在本发明的技术构思范围内，可以对本发明的技术方案进行多种简单变型，这些简单变型均属于本发明的保护范围。
