本发明的实施方式
为了便于本领域技术人员的理解，下面结合附图对本发明作进一步的描述，并不能用来限制本发明的保护范围。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的各种方式可以相互组合。
参见图1，本发明实施例提出了一种检测信号的方法，包括：
步骤100、检测设备根据从第一数据码流中恢复出的时钟在标准电压阈值同步接收第二数据码流得到基准测试点的第一数据。
本步骤中，检测设备如何根据从第一数据码流中恢复出的时钟和标准电压阈值同步接收第二数据码流得到基准测试点的第一数据属于本领域技术人员的公知技术，并不用于限定本发明的保护范围，这里不再赘述。
本步骤中，基准测试点是指在以电压阈值和时钟为坐标轴的坐标系中，从第一数据码流中恢复出的时钟和标准电压阈值所对应的点。
本步骤中，根据恢复出的时钟在标准电压阈值同步接收第二数据码流得 到基准测试点的第一数据是指：根据恢复出的时钟在每一个信号周期的中心位置接收信号，将接收的信号与标准电压阈值进行比较，如果接收的信号大于或等于标准电压阈值，则该信号周期对应的码元取值为1，如果接收的信号小于标准电压阈值，则该信号周期对应的码元取值为0。
例如，信号周期为5毫秒(ms)，每一个信号周期从5k ms开始，k为大于或等于0的整数，则根据恢复出的时钟在2.5k ms处接收第二数据码流。
步骤101、检测设备分别采用不同相位的时钟在不同的电压阈值同步接收第二数据码流得到不同非基准测试点的第二数据。
本步骤中，不同相位的时钟是指偏离恢复出的时钟不同的相位的时钟。
例如，根据恢复出的时钟在2.5k ms处接收第二数据码流，则可以在0.5k ms、k ms、1.5k ms、2k ms等同步接收第二数据码流。0.5、1、1.5、2等表示不同的相位。
本步骤中，如何分别采用不同相位的时钟在不同的电压阈值同步接收第二数据码流得到不同非基准测试点的第二数据属于本领域技术人员的公知技术，并不用于限定本发明的保护范围，这里不再赘述。
本步骤中，每一个非基准测试点是指在以电压阈值和时钟为坐标轴的坐标系中，每一个时钟和每一个电压阈值所对应的点。
其中，步骤100和步骤101不分先后顺序执行。

其中，SER为每一个非基准测试点的误码率，N为每一个非基准测试点的第二数据中与第一数据不同的码元的个数；M为每一个非基准测试点的第二数据或第一数据的码元总数。
其中，M的取值与相邻两个误码率之间的差值相关。例如，如果相邻两个误码率之间的差值为10-9，则M要求在109以上。
该方法之前还包括：
检测设备将单位间隔(UI，Unit Interval)区域划分为多个区域，预先设置划分得到的区域和操作之间的对应关系。
其中，UI相当于一个时钟周期。
其中，UI区域是指以时钟坐标轴上UI和电压阈值坐标轴上最大电压值和最小电压值之间的差值所对应的区域，如图2所示。
其中，检测设备在对UI区域进行划分时，可以划分成相互嵌套的任意图形，如正方形、长方形、圆形、椭圆形等，如图3(a)～(d)所示。
该方法还包括：
步骤103、检测设备确定生成的眼图所在的区域，在对应关系中查找确定出的区域对应的操作，执行查找到的操作。
本步骤中，检测设备可以通过眼图上的点来确定生成的眼图所在的区域。例如，如果眼图上超过一定数量的点落在某一区域内，则说明眼图落在该区域上。眼图可以同时落在一个或多个区域上，当眼图落在多个区域上时，可以按照优先级别依次执行每一个区域对应的操作，也可以只执行优先级别最高的区域对应的操作，也可以确定眼图所在的区域为级别最高的区域。
其中，可以设置越往里的区域优先级别越高。
本步骤中，操作包括但不限于以下任意组合：红色告警、保护倒换、黄色告警等。
通过本发明实施例的方案，通过第二数据码流的眼图对第二数据码流进行检测，实现了对物理层的信号质量的检测。
