背景技术
PoE(Power Over Ethernet)指的是在现有的以太网Cat.5布线基础架构不作任何改动的情况下，在为一些基于IP的终端传输数据信号的同时，还能为此类设备提供直流供电的技术。PoE技术能在确保现有结构化布线安全的同时保证现有网络的正常运作，最大限度地降低成本。
PoE有时也被称为基于局域网的供电系统(PoL，Power over LAN)或有源以太网(Active Ethernet)，有时也被简称为以太网供电，这是利用现存标准以太网传输电缆的同时传送数据和电功率的最新标准规范，并保持了与现存以太网系统和用户的兼容性。IEEE 802.3af标准是基于以太网供电系统PoE的新标准，它在IEEE 802.3的基础上增加了通过网线直接供电的相关标准，是现有以太网标准的扩展，也是第一个关于电源分配的国际标准。
一个完整的PoE系统包括供电端设备(PSE，Power Sourcing Equipment)和受电端设备(PD，Powered Device)两部分。PSE是为以太网客户端设备供电的设备，同时也是整个PoE以太网供电过程的管理者；而PD是接受供电的PSE负载，即PoE系统的客户端设备，如IP电话、网络安全摄像机、AP及掌上电脑(PDA)或移动电话充电器等许多其他以太网设备(实际上，任何功率不超过13W的设备都可以从RJ45插座获取相应的电力)。两者基于IEEE 802.3af标准建立有关受电端设备PD的连接情况、设备类型、功耗级别等方面的信息联系，并以此为根据PSE通过以太网向PD供电。
在相关技术中，PoE的供电过程一般如下：PSE在端口输出较小的电压，然后再输出另一电压，通过两个电压对应电流的变化得到一个负载阻抗，如果这个负载阻抗在标准范围之内，那么即可判断已经连接到一个标准的PD；当检测到PD之后，PSE会根据负载阻抗的大小，为PD进行分类，并且评估此PD所需的功率损耗，进而为其供电。即在现有的以太网供电过程中，PSE一直为PD提供固定的供电功率，但是PD并不是一直处于满负荷运行，有时是处于空闲或休眠状态，这将导致电能浪费。
上述内容仅用于辅助理解本发明的技术方案，并不代表承认上述内容是现有技术。

当在以太网系统中包括多个PD时，则在该步骤中，分别获取各个PD的运行模式。
