需要说明的是：无线通讯是基于宽带电力线载波通讯(PLC)的通讯；有线通讯包括但不限于：控制器局域网络(CAN)、RS485、HBS等通讯。
需要说明的是：在宽带电力线(PLC)通讯技术的相关技术中，其PLC通讯自身是属于主从方式的网络架构，也就是说PLC通讯需要确定主节点来负责电力线网络中所有站点的通讯管理和维护。
为了摆脱宽带电力线(PLC)通讯技术的相关技术中，其PLC通讯自身是属于主从方式的网络架构，可选地，在本申请实施例提供的多联空调机组的网络系统中，多个内部设备与电力线之间均设有电力线载波通讯模块，其中，每个内部设备均通过电力线载波通讯模块进行电力线载波通讯，也即，每个内部设备均可以通过电力线载波通讯模块进行电力线载波通讯，进而达到建立了一种多主方式的空调机组内网络结构， 实现任意内部设备(任意节点)任意时刻均可自主发送、接收数据。
如图2所示，设置为空调机组内部设备之间的数据交换的电力线载波通讯网络10分成上行网络和下行网络，其中，上行网络是指：多个电力线载波通讯模块之间通过电力线进行数据交换的上行网络；下行网络是指：电力线载波通讯模块与其对应的空调内机(空调内机控制器)/空调外机(空调外机控制器)之间进行数据交换的下行网络。而上行网络与下行网络通过电力线载波通讯模块进行数据交互，从而实现了空调机组内部设备之间的数据交互。

作为一个可选的示例，可选地，在本申请实施例提供的多联空调机组的网络系统中，电力线载波通讯模块包括：数据管理子模块，设置为收集、存储和处理信息数据；和/或信息发送子模块，设置为依据信道状态发送信息。
需要说明的是：空调机组内部设备不仅仅包括空调外机和空调内机，同时还包括：其他待连接空调机组内部设备之间进行数据通讯的电力线载波通讯网络10的设备，例如线控器。
需要说明的是，基于本申请提供的多联空调机组的网络系统是采用无线通讯与有线通讯相结合的网络架构，且空调机组之间采用有线通讯的方式，因此该多联空调机组的网络系统可以兼容多种通讯网络，也可以兼容任何接入该有线通讯网络20的设备。例如，如图3所示，可选地，在本申请实施例提供的多联空调机组的网络系统中，有线通讯网络20连接以下设备至少之一：上位机网关、集中控制器以及远程网络监控。
本申请实施例还提供了一种多联空调机组的网络系统的建立方法，需要说明的是，本申请实施例的多联空调机组的网络系统的建立方法可以用于建立本申请实施例所提供的用于多联空调机组的网络系统。以下对本申请实施例提供的多联空调机组的网络系统进行介绍。
图4是根据本申请实施例提供的多联空调机组的网络系统的建立方法的流程图。如图4所示，该方法包括：
步骤S401：对多个空调机组的内部设备进行配对，得到配对结果。
步骤S402：依据配对结果，组建各个空调机组对应的电力线载波通讯网络，其中，每个电力线载波通讯网络用于通讯连接其对应的空调机组多个内部设备，内部设备包 括空调外机和空调内机。
步骤S403：组建各个空调机组之间的有线通讯网络，其中，有线通讯网络用于通讯连接多个空调机组的空调外机。
步骤S404：依据有线通讯网络和多个电力线载波通讯网络，建立多联空调机组的网络系统。
本申请实施例提供的多联空调机组的网络系统的建立方法，通过对多个空调机组的内部设备进行配对，得到配对结果；依据配对结果，组建各个空调机组对应的电力线载波通讯网络，其中，每个电力线载波通讯网络用于通讯连接其对应的空调机组多个内部设备，内部设备包括空调外机和空调内机；组建各个空调机组之间的有线通讯网络，其中，有线通讯网络用于通讯连接多个空调机组的空调外机；依据有线通讯网络和多个电力线载波通讯网络，建立多联空调机组的网络系统，解决了相关技术中有线通讯连接多个空调设备时，其走线安装困难以及走线成本高的问题。通过上述步骤建立多联空调机组的网络系统，即令空调机组内部设备均利用供电电源线接入供电电力线网络，通过宽带电力线载波通讯技术(PLC)，以供电电力线网络为传输媒介，实现空调机组内部设备之间的数据交互；以及令每个空调机组的外机通过通讯数据线进行连接，实现空调机组之间的数据交互。达到了在空调机组安装时不需布置空调机组内的通讯走线，只需在空调机组之间确认走线的技术效果。
需要说明的是：由于在同一电力线网络中可以存在多个空调机组，即存在多个电力线载波通讯网络。但是各个空调机组对应的电力线载波通讯网络又必须相互独立、互不干涉，采用保证电力线载波通讯网络的正常数据交换，以及保证空调机组的正常运行。而为了达到上述技术目的，本申请通过步骤S401，对多个空调机组的内部设备进行配对，进而区别不同空调机组的内部设备，并通过步骤S402，依据配对结果，组建各个空调机组对应的电力线载波通讯网络，且各个空调机组对应的电力线载波通讯网络相互独立、互不干涉。进而再通过步骤S403，组建各个空调机组之间的有线通讯网络，形成多联空调机组的网络系统。
需要说明的是：在宽带电力线(PLC)通讯技术的相关技术中，其PLC通讯自身是属于主从方式的网络架构，也就是说PLC通讯需要确定主节点来负责电力线网络中所有站点的通讯管理和维护。
为了摆脱宽带电力线(PLC)通讯技术的相关技术中，其PLC通讯自身是属于主从方式的网络架构，可选地，在本申请实施例提供的多联空调机组的网络系统的建立方法中，多个内部设备与电力线之间均设有电力线载波通讯模块，其中，每个内部设备均通过电力线载波通讯模块进行电力线载波通讯，也即，每个内部设备均可以通过 电力线载波通讯模块进行电力线载波通讯，进而达到建立了一种多主方式的空调机组内网络结构，实现任意内部设备(任意节点)任意时刻均可自主发送、接收数据。
如图2所示，设置为空调机组内部设备之间的数据交换的电力线载波通讯网络分成上行网络和下行网络，其中，上行网络是指：多个电力线载波通讯模块之间通过电力线进行数据交换的上行网络；下行网络是指：电力线载波通讯模块与其对应的空调内机(空调内机控制器)/空调外机(空调外机控制器)之间进行数据交换的下行网络。而上行网络与下行网络通过电力线载波通讯模块进行数据交互，从而实现了空调机组内部设备之间的数据交互。
需要说明的是：多个电力线载波通讯模块之间通过电力线进行数据交换的上行网络，采用CSMA/CD的通讯机制，使上行网络实现机组之间的数据交互。也即电力线载波通讯模块之间具有数据管理和仲裁机制，以使任意节点在任意时刻均可以自主发送数据，避免数据发送时产生发送纠纷的情况。
为了精准地建立电力线载波通讯网络，可选地，在本申请实施例提供的多联空调机组的网络系统的建立方法中，依据配对结果，组建各个空调机组对应的电力线载波通讯网络包括：空调机组的空调外机读取空调机组的唯一标识信息；空调机组的空调外机依据配对结果中空调机组的空调外机对应的空调内机发送唯一标识信息；空调机组的空调外机接收空调机组的空调内机基于唯一标识信息返回的确认信息；空调机组的空调外机依据唯一标识信息和确认信息，建立电力线载波通讯网络。
也即，宽带电力线载波通讯技术(PLC)在物理上解决了空调机组的通讯问题，而空调机组的唯一标识信息(唯一的网络地址)解决了内部设备之间的识别。进而保证了空调机组的正常运行。
需要说明的是：空调机组内部设备节点之间有效通讯交互的还要依赖于软件层协议的制定。
作为一个可选的示例，在空调机组通电之后，空调机组的主控控制模块读取主板控制器中ID识别码，在与电力线载波通讯模块建立串口通讯有效连接后，将ID识别码下发至电力线载波通讯模块，直至接收到电力线载波通讯模块ID识别码的确认回复。PLC模块之间通过此唯一的ID识别码进行组网，组网成功后，各设备就按此功能码作为自身IP地址，从而进行数据交互。
需要说明的是：电力线载波通讯具有通讯速度快、通讯数据量大、可靠性高等优点；但也存在供电电力线网络结构较为复杂、通讯干扰和数据量时变性较大等特性。
基于上述电力线载波通讯的自身特性，可选地，在本申请实施例提供的多联空调机组的网络系统的建立方法中，依据配对结果，组建各个空调机组对应的电力线载波 通讯网络之后，该方法还包括：确定电力线载波通讯网络的预设通讯指标的实际测量值；依据预设通讯指标的实际测量值，调节电力线载波通讯模块的功率和内部设备的串口通讯波特率。也即，通过检测宽带供电电力线通讯网络的通讯质量，进而设定内部设备的串口通讯波特率和电力线载波通讯模块的功率，以适应电力线载波通讯模块的通讯波特率，进而提高电力线载波通讯网络通讯效率，以实现对多联空调机组的有效控制。
需要说明的是：电力线载波通讯网络的预设通讯指标的实际测量值包括但不限于：电力线载波通讯网络的通讯速率、通讯数据量、通讯可靠性、通讯波特率等。
并且，本申请可以实现如下技术效果：1、采用无线通讯与有线通讯相结合的网络架构，实现空调机组内无线连接，不需要在外机与内机之间单独连接通讯线，而是以供电电力线网络为数据通讯线，将多联机组供电电源线接入供电电力线通讯网络，达到了省去通讯线安装的工程量，也减少了通讯线路接触不良的现象；2、采用无线通讯与有线通讯相结合的网络架构，且空调机组之间采用有线通讯，达到有线通讯网络可以兼容市面上现有的通讯网络，兼容任何接入该有线通讯网络的设备；3、通过检测宽带供电电力线通讯网络的通讯质量，自适应确定机组的通讯速率、电力线载波通讯模块功耗，从而提高通讯可靠性；4、通过在多个内部设备与电力线之间均设有电力线载波通讯模块，使电力线载波通讯网络成为多主机结构通讯网络，实现任意内部设备(任意节点)任意时刻均可自主发送、接收数据，提高了通讯效率，解决了主从网络架构方式效率慢的问题。
需要说明的是，在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行，并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
