为了更好地理解本发明实施例，以下结合优选的实施例对本发明做进一步解释。
本发明优选实施例的目的在于自动检测信号噪声，当信号噪声较大时候实现自动切换电力线相序，让信号在相对干净的电力线中传输，从而提高信号的可靠性。
本发明优选实施例提供一种接在三相电源下信道检测并自动切换装置，具体的可以参考上述图1，检测三相电力线上的信号噪声，并自动切换到噪声较小信道。
如图1所示，信道切换装置(相当于上述实施例中的信道切换模块)连接在L1、L2、L3、N上。
图3是根据本发明优选实施例提供的信道切换流程示意图，如图2所示，结合图1，该流程包括：
信道检测并自动切换装置上电时自动检测接到L1和N上、接到L2和N上、接到L3和N上的内机IP，并存储这些信息，当系统内机数量增加或减少时，装置重新检测并存储。
一般信号在L1上传输时信号耦合到L2和L3上确保接到L2和L3下的模块能有效接收信号。本发明优选实施例提供了一种信道自动切换技术，噪声检测模块内部设定噪声阈值，当噪声超过这个阈值时可能导致通讯异常。该噪声检测模块发送实时噪声幅值给芯片，芯片通过选取某一时间段的噪声幅值计算均方根值，时间段的选取可以根据实际测试情况调整。该芯片将获得均方根值反馈给噪声检测模块，噪声检测模块将均方根值与该阈值比较，在该均方根值大于该阈值的情况下，向信道切换装置发送切换命令，指示信道切换装置对信号进行信道切换，或者噪声检测模块将噪声阈值也发送给了芯片，芯片将得到的均方根值与噪声阈值比较，在该均方根值大于该阈值的情况下，向信道切换装置发送切换命令，指示信道切换装置对信号进行信道切换。当信号在L1信道上传输时，此时L1上噪声最大且大于设定阈值，L2上噪声最小，芯片或噪声检测模块发出信号切换命令，然后信号切换到信道L2上，且停止此时间段信号耦合到L2和L3上，切换到新信道后，芯片将此时间段数据发送给信道切换装置，信道切换装置存储数据传输给接到L1和L2上的内机，避开噪声干扰最大的信道。
通过上述优选实施例，可以实现以下技术效果：避开噪声最大信道，并自动切换；噪声较大超过阈值时候，通过信道切换装置作为数据中转站，把数据传输给其他信道； 当噪声大于阈值时会影响通讯，实时监测信道噪声。进而可以有效提高通讯质量。
