具体实施方式
为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分的实施例，而不是全部的实施例。基于本申请中的实施例，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，都应当属于本申请保护的范围。
需要说明的是，本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含。
本申请提供了一种多联空调机组***的实施例。
本申请实施例提供的多联空调机组***包括至少一个空调机组和控制设备，每个空调机组包括多个空调机，空调机可以是空调内机或空调外机。多联空调机组***中的至少一个空调机组通过电力线(供电电源线)接入电力线载波PLC通讯网络且采用PLC通讯技术进行通讯。
至少一个空调机组包括第一空调机组，控制设备用于通过无线网络与第一空调机组进行通讯，控制设备可以包括以下至少一种：线控器、移动终端、遥控器，控制设备能够通过无线网络与第一空调机组进行通讯。可选的，在控制设备包括多个线控器、 第一空调机组为空调内机组且空调内机组包括多个空调内机的情况下，多个线控器与多个空调内机之间可以是一一对应地，每个线控器与对应的空调内机之间通过无线网络进行通讯。由于控制设备与第一空调机组通过无线网络通讯，第一空调机组中的每个空调机可以包括用于与控制设备进行无线通讯的无线通讯模块，和用于与PLC通讯网络中的其它设备采用PLC通讯技术进行通讯的电力载波模块，其中，无线通讯模块可以为以下之一：无线保真WIFI模块、蓝牙模块、红外模块。
进一步地，至少一个空调机组还包括第二空调机组，控制设备可以通过第一空调机组与第二空调机组进行通讯。例如，如图1所示，多联空调机组***中包括第一空调机组11和第二空调机组12，以及控制设备20，其中，控制设备20与第一空调机组11之间通过无线网络进行通讯，第一空调机组11和第二空调机组12通过电力线接入同一个PLC网络中，控制设备20能够通过第一空调机组11与第二空调机组12进行通讯。该实施例提供的多联空调机组***无需额外进行布线，仅需利用已经存在的电力线组成PLC通讯网络，每个空调机均可以通过电力线接入PLC通讯网络中进行通讯，而控制设备(例如，线控器)与空调机之间也无需通过有线连接，降低了安装工程的复杂度和成本。
可选的，第一空调机组为空调内机组，第二空调机组为空调外机组，也即，该实施例提供的多联空调机组***的空调内机组与控制设备之间通过无线网络进行通讯，而空调内机组和空调外机组通过PLC通讯网络进行通讯。
作为上述实施例一种可选的实施方式，由于至少一个空调机组可以包括多个空调机(空调机可以是空调内机或空调外机)，每个空调机可以包括通过串口模块通讯的电力载波模块(PLC模块)和控制器，每个空调机的电力载波模块通过对应的电力线接入PLC通讯网络，其中，电力载波模块用于利用电力线传输数据，控制器用于处理数据。
例如，如图2所示，该实施例提供的多联空调机组***包括空调内机组和空调外机组、以及线控器，空调外机组中的每个空调外机包括外机控制器和PLC模块，每个空调外机的外机控制器和PLC模块之间通过串口模块进行串口通讯，空调内机组中的每个空调内机包括内机控制器和PLC模块，内机控制器与PLC模块之间通过串口模 块进行串口通讯，线控器包括线控器控制器，线控器控制器与空调内机的内机控制器之间通过无线通讯模块进行无线通讯。每个空调内机的PLC模块和每个空调外机的PLC模块通过电力线组成PLC通讯网络，采用PLC通讯技术进行通讯。
现有技术中的PLC通讯网络通常是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PLC网络中所有节点的通讯管理和维护。为了摆脱其主从的通讯方式，作为一种可选的实施例，PLC通讯网络中的每个PLC模块之间采用载波监听多路访问/冲突检测CSMA/CD通讯机制进行通讯，使整个PLC通讯网络实现了多主结构，网络拓扑中的任意节点(每个节点为一个空调机)可实现自主发送和接收数据，解决了现有技术中采用主从网络架构效率慢的问题。
可选的，PLC通讯网络还可以用于连接以下设备至少之一：调试设备、集中控制器以及网关设备。
下面结合图3为上述实施例提供的多联空调机组***的一种可选的实施方式进行说明如下：
如图3所示，在该实施例提供的多联空调机组***中，所有室内机(也称空调内机、内机)组和室外机(也称空调外机、外机)组都是利用供电电源线(电力线)接入供电电力线网络(PLC通讯网络)，通过宽带电力线载波通讯技术(PLC通讯技术)进行通讯，PLC通讯网络中的通讯数据以供电电力线网络为传输媒介，实现空调机组之间的互相通讯。内机和线控器之间则采取无线通讯的通讯方式连接。该实施例提供的多联空调机组***省去了工程安装的通讯线，利用无线网络和已有的电力线进行通讯，实现了无通讯线的内外机网络架构。
该实施例提供的多联空调机组***采用PLC通讯+无线通讯相结合的网络架构，如图3所示，网络1为PLC通讯网络，PLC通讯网络包括空调内机组和空调外机组，进一步地，还可以包括如图3所示的调试设备、集中控制器以及网关设备。网络2为无线通讯网络，无线通讯网络为空调内机组与线控器之间的通讯网络，每个空调内机与对应的线控器之间通过无线网络进行通讯。
PLC通讯与无线通讯两层网络是互通的，具体而言，PLC通讯与无线通讯两层网 络通过内机连接，通过内机作为通讯网关将两层网络连通。这种通讯网络架构可以使用无线的线控器、遥控器、手机等无线设备控制空调机组，无线通讯方式包括但不限于WIFI、蓝牙、红外等通讯方式。
该实施例的多联空调机组***提供的两种通讯入口(PLC通讯和无线通讯)为未来物联网奠定基础，例如，远程监控设备或其它第三方控制设备均可以通过PLC通讯或无线通讯的方式接入并控制空调机组。目前市场上无线通讯设备、PLC电力猫等设备越来越多，本申请可根据实际情况，灵活选择不同的通讯方式控制空调机组，或与其它电器设备连接，为智能家居提供有利条件。
该实施例提供的多联空调机组***中的通讯网络分成上行/下行网络，如图2所示，上行网络为PLC模块与其它PLC模块之间的PLC通讯网络，下行网络为PLC模块与其对应的空调机控制器之间的串口通讯网络。具体而言，PLC模块与其它PLC模块之间组成上行网络，采用CSMA/CD的通讯机制，PLC模块与其它PLC模块之间具有数据管理、仲裁机制，使网络拓扑中的任意节点(PLC模块)在任意时刻均可以自主发送和接收数据，使上行网络中空调机之间的数据交互实现了多主结构，然后，每个空调机中的控制器与PLC模块组成下行网络，实现空调机内部的控制器与PLC模块之间的数据交互。下行网络的数据与上行网络的数据通过PLC模块进行数据交互，从而实现了空调机之间的数据交互。
PLC通讯技术具有通讯速度快、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点，为实现多联空调机组***有效控制，在实际应用中，应检测PLC通讯网络的通讯质量，进而设定每个空调机的控制器的串口通讯波特率，并设定PLC模块功率，以适应PLC通讯模块的通讯波特率，从而提高网络通讯效率。
上述本申请实施例的顺序不代表实施例的优劣。
在本申请的上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。在本申请所提供的几个实施例中，应该理解到，所揭露的技术内容，可通过其它的方式实现。
以上所述仅是本申请的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本申请的保护范围。
工业实用性
本申请通过至少一个空调机组，通过电力线接入电力线载波PLC通讯网络且采用PLC通讯技术进行通讯，其中，至少一个空调机组包括第一空调机组；控制设备，设置为通过无线网络与第一空调机组进行通讯，解决了相关技术中的多联空调机组工程安装成本高的技术问题，进而实现了能够降低多联空调机组安装成本的技术效果。
