相关技术中，基于宽带电力线载波通信的多联空调机组通信网络，以供电电力网络为数据通信线，可以省去通信线安装的工程量，减少通信线路接触不良的现象，但采用PLC通信需要对内、外机、线控器进行一一配对，空调机组才能正常运行，从而造成空调机组配对过程复杂，操作不方便问题。为解决上述问题，本申请实施例提供了相应的解决方案，以下详细说明。
根据本申请实施例，提供了一种空调系统的实施例，图1是根据本申请实施例的空调系统，如图1所示，该空调系统包括：
多个空调机组；
多个空调机组中的至少一个外机与至少一个内机接入电力网，并采用第一通信方式进行通信；至少一个内机与相应的线控器通过第二通信方式进行通信；
其中，第一通信方式包括：PLC方式；第二通信方式包括：除PLC方式之外的通信方式。第二通信方式包括以下至少之一：内机与线控器通过CAN总线通信；内机与线控器通过RS485总线通信；内机与线控器通过家庭总线系统HBS进行通信。
对于第一通信方式，即PLC方式，可以通过在空调系统中设置PLC模块实现，例如，如图2所示，空调系统中还包括：与多个空调机组对应的多个PLC模块20；多个PLC模块20中任意一个PLC模块的一端接入电力网中，另一端接入多个空调机组的控制器22，设置为将从电力网接收的数据发送至至少一个空调机组；或者，将来自至少一个空调机组的控制器的待传输数据通过电力网传输至空调系统中的其他PLC模块。可选地，在空调机组为外机时，上述控制器为外机的控制器220；上述空调机组为内机时，上述控制器为内机的控制器222。
可选地，多个PLC模块之间采用CSMA/CD通信协议进行通信；多个PLC模块与多个空调机组的控制器之间通过串行通信接口连接，如图2所示，空调机组的主控控制器(例如外机的控制器或内机的控制器)与PLC模块间，通过串口通信方式交互通信数据；PCL模块与其他PLC模块之间，通过供电电力线组成通信网络，PLC模块之间采用CSMA/CD通信机制，并且PLC模块可以采用数据管理仲裁机制自主发送或接收数据，可以使整个多联空调网络架构实现多主结构，网络拓扑中任意节点可实现自主发送和接收数据，解决了主从网络架构方式效率慢问题。
作为一个可选实施例，PLC模块可以独立设置在一个电路板中，也可以和相应机组的控制器设置于同一电路板中，例如，对于与内机对应的PLC模块，可以与内机的控制器共同设置于内机的主板中。
其中，由于PLC模块间可以通过电力网进行通信，因此，可以通过PLC组成空调系统中的PLC通信网络。为实现空调系统中机组间的PLC通信，PLC模块可以在将待传输数据发送至电力线之前，对带传输数据进行调制，以使得待传输数据适于在电力线上传输，例如将载有待传输数据的高频信号加载于电流中，并通过电力线传输；在接收侧，将高频信号从电流中解析出来，得到上述待传输数据。
正如上面所述，PLC模块可以实现自主数据传输，此时，多个PLC模块中的任意一个PLC模块，还设置为在检测到来自任意一个PLC模块内部的触发事件时，将待传输数据通过电力网发送至其他PLC模块。PLC模块内部的触发事件是指数据管理仲裁机制触发的事件，例如，检测到当前PLC通信网络空闲、PLC模块内部的定时触发事件、PLC内接收到多个待传输数据时，依据预设优先级自主发送数据等。
相关技术中，在宽带电力线通信技术(PLC)中,PLC通信自身是属于主从方式的网络架构，也就是说PLC通信需要确定主节点来负责电力网络中所有站点的通信管理和维护。为了摆脱其主从的通信方式，正如上面所述，本申请实施例中的PLC模块可以实现自主传输数据，因此，具有上述PLC模块的空调系统中可以具有一个多主结构的通信网络，从而实现任意节点任意时刻均可自主发送、接收数据。具体地：
1)上行网络：PLC模块与其他PLC模块之间的通信网络；
2)下行网络：PLC模块与空调控制器之间的通信网络。
首先PLC模块与其他PLC模块之间组成上行网络，采用CSMA/CD的通信机制，使上行网络实现机组之间的数据交互；然后，单个空调机组的控制器与PLC模块组成下行网络，实现空调控制器与PLC的数据交互。下行网络数据与上行网络数据通过PLC模块进行数据交互，从而实现了空调机组内部的数据交互。PLC模块与其他PLC模块 之间具有数据管理、仲裁机制，使任意节点在任意时刻均可以自主发送数据，实现了多主的多联空调网络架构。
可选地，多个PLC模块中的任意一个PLC模块，还设置为检测电力网的通信质量；并依据通信质量调整任意一个PLC模块和控制器之间的传输速率和/或任意一个PLC模块的功率。
具体地，可以通过信号强度表示通信质量，则检测电力网的通信质量并依据通信质量进行调整：依据信号强度和预设的比较结果确定是否对PLC模块和控制器之间的传输速率和/或任意一个PLC模块的功率进行调整，例如，信号强度大于等于第一预设阈值时，将传输速率和功率均增大或将传输速率和功率中的其中一个参数增大，同理，信号强度小于第一预设阈值时，将传输速率和功率均减小或将传输速率和功率中的一个参数减小。根据电力网络质量自适应通信速率、通信模块功率等，提高了外机与内机之间数据通信的效率，保证了数据传输的可靠性。
本申请实施例采用了宽带电力线载波通信，基于宽带电力线通信的多联空调机组通信控制网络,具有宽带电力线通信的通信速度快、通信数据量大、可靠性高等优点，但也存在供电电力网络结构较为复杂、通信干扰和数据量时变性较大等特点。为实现多联空调机组的有效控制，首先应检测电力网的通信质量，进而设定多联空调机组主控控制模块的串口通信波特率，设定PLC模块功率，以适应宽带电力线载波通信控制模块的通信波特率，从而提高网络通信效率。
PLC电力载波通信技术在物理上解决了空调机组的通信问题，各内、外机节点需要有唯一的网络地址用于设备之间的识别ID，且一个空调系统中，以外机为中心，每台内机均需要和外机进行配对，这样才能保证控制网络中的每台空调机组正常运行。因此，空调网络中，需要进行地址识别从而将空调的内外机进行配对。而系统中每个内机与各自的线控器之间有且有独立的通信线进行连接，这样为内外机的配对带来便利。例如：
外机还设置为获取外机的本地外机标识ID，并将本地外机标识发送至至少一个内机；至少一个内机，还设置为获取目标外机的目标外机ID，并在目标外机ID和本地外机ID一致时，向外机发送确认指令；外机，还设置为在接收到确认指令后，将至少一个内机的内机ID与外机进行绑定。其中，外机包括控制器，通过控制器获取外机的本地标识ID，并将本地外机标识发送至至少一个内机；内机包括内机控制器；将至少一个内机的内机ID与外机进行绑定，即将至少一个内机与外机进行配对。
在本申请实施例中，提供一种可选的应用场景：空调机组上电之后，进入首次配 对模式：
首先，外机的控制器读取并显示自身的识别ID，同时通过PLC模块发送至电力线中所有内机节点；
然后，在每个内机节点侧，通过线控器输入需要配对的目标外机的目标外机ID，线控器发送目标外机ID至内机控制器。
最后，当内机控制器接收到外机控制器发送的ID与线控器输入的目标外机ID一致时，则内机控制器发送配对确认信号至相应的外机控制器。外机控制器收到确认命令后，把该内机的ID列入配对列表，表示外机与内机配对完成，并发送配对完成标志至对应的内机控制器，内机所在的线控器显示成功字符。
按此方式完成其余内机的配对后，空调网络组网配对完成，空调机组即可通信和运行。
可选地，如图3所示，多个空调机组还包括：集中控制器、网关设备，多个空调机组还可以包括调试设备。
通过宽带电力线载波通信与有线通信相结合的多联机空调网络系统拓扑结构，以各空调机组为通信站点，以电源线和有线通信线为通信介质的通信网络拓扑结构，为多联空调机组的安装提供了极大的便利性。内机与外机处于PLC网络，但内机与线控器是通过有线通信方式连接，即通过物理连接方式，无需配对，这样为工程的调试以及配对带来了便利。

步骤S404，PLC模块采用第二通信方式将数据发送至第一机组的控制器；
其中，第一通信方式包括：电力线通信PLC方式；第二通信方式包括：除PLC方式之外的通信方式。

可选地，PLC模块在检测到来自任意一个PLC模块内部的触发事件时，将来自控制器的待传输数据通过电力网发送至其他PLC模块。
