需要说明的是，上述系统1可以认为是上述实施例中的一个多联机空调系统，系统2也可以认为是上述实施例中的一个多联机空调系统，但并不限于此。

图5是根据本发明优选实施例提供的自动组网流程示意图，如图5所示，该流程包括：
步骤1、上电后，外机可以但不限于利用自身具备的条形码建立唯一的通讯网络。
步骤2、通过操作让外机发起组网，同时禁止白名单，即允许内机无网络密钥入网，并实时统计入网内机数量。
步骤3、未加入网络的内机监听附近的通讯网络，并判断网络信号强度，如果出现网络信号强度大于设定阈值(相当于上述实施例中的预设阈值)的(该阈值可根据电力线载波通讯信号跨过电表的衰减值来制定)，且为开放网络，则主动加入该外机网络。
步骤4、外机统计入网内机数量，并对逐台内机进行试运行确认：
1)当检测到环境温度Th≥Ts时，制冷模式运行，运行一段时间后，检测系统高压Pg，当Pg≤Ps1(相当于上述实施例中的第一阈值)则确认为本系统内机，并写入白名单，否则非本系统内机，删除入网，内机离网；
2)当检测到环境温度Th＜Ts时，制热模式运行，运行一段时间后，检测系统低压Pd，当Pd≥Ps2(相当于上述实施例中的第二阈值)则则确认为本系统内机，并写入白名单，否则非本系统内机，删除入网，内机离网。
步骤5、如果所有入网内机已经完成试运行，则完成组网，启动白名单，否则重复步骤4。
由此，实现采用电力线载波通讯技术的多联机自动入网、自动确认，解决内机无法操作及显示的入网问题，组网可靠便捷。
