为了更清楚地说明本发明的实施例或现有技术中的技术方案，下 面将对描述背景技术和实施例时所使用的附图作简单的介绍。显而易 见地， 下面附图中描述的仅仅是本发明的一部分实施例，对于本领域 普通技术人员来讲， 在不付出创造性劳动的前提下，还可以根据这些 附图和描述得到其他的附图或实施例，而本发明旨在涵盖所有这些衍 生的附图或实施例。
图 1是 FTTdp组网中反向供电线路示意图； 图 2是本发明实施例反向供电方法流程示意图； 图 3是本发明实施例反向供电设备模块示意图；
图 4是本发明实施例反向供电***示意图。
具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白， 以下结合 附图及实施例， 对本发明进行进一步详细说明。 应当理解， 此处所描 述的具体实施例仅仅用以解释本发明， 并不用于限定本发明。 显然， 所描述的实施例仅仅是本发明一部门实施例， 而不是全部的实施例。 基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动 前提下所获得的所有其他实施例， 都属于本发明保护的范围。
图 1是本发明实施例具体应用场景图， 如图 1所示， 在一个家庭 内部走线环境下， 存在多个面板接口 （图中以 3个作为示例）， 分别 标记为接口 1、 接口 2和接口 3 , 在其中任意一个面板接口， 连接一 个反向供电设备 (图 1中为连接接口 1 ) , 通过线路为配线设备供电， 这里的配线设备可以是 FTTdp ( Fiber To The Distribution Point , 光纤 到配线点）设备， 也可以称作线路交接箱， 这里的线路釆用双绞线。
本发明一实施例提供了一种反向供电方法， 如图 2所示：
S220,反向供电设备启动线路测试模块判断线路上是否存在用户 终端设备。
其中， 在反向供电设备启动线路测试模块之前， 开启配线设备和 供电设备的开关，使供电***处于不供电状态。反向供电设备判断线 路上是否存在用户终端设备， 这里的用户终端设备可以是电话机， 这 里的线路可以通过双绞线连接，这里的判断方式可以是通过测试线路 上的电容是否达到一临界值， 如果通过测试发现， 线路上的电容超过 了临界值， 那么认为线路上很可能存在用户终端设备， 这里的电容临 界值可以参考为大于 l uF (微法）， 即如果测试线路上的电容值大于 luF时， 推测线路上存在用户终端设备。
可选地 ,这里的判断方式也可以通过测试线路上的电阻是否达到 一临界值， 如果通过测试发现， 线路上的电阻超过了临界值， 那么认 为线路上很可能存在用户终端设备，这里的电阻临界值可以参考为大 于 300欧姆， 即如果测试线路上的电阻值大于 300欧姆时，推测线路 上存在用户终端设备。 S230,如果推测线路上没有存在用户终端设备， 反向供电设备通过铃流发送模块发送铃流信号，发送一段时间，检测 是否有用户终端摘机。
其中，如果测试线路上的电容值小于 luF时，推测线路上没有存 在用户终端设备。 可选地， 反向供电设备向线路上发送铃流信号， 这 里的铃流信号可以是电话铃声， 频率可以是 25HZ,发送一段时间后， 这里的一段时间， 可以是大于 1秒的时间，检测用户终端设备是否存 在被摘机情况， 这里的用户终端设备可以是电话机， 这里的摘机情况 可以是用户在家中接听电话行为。
S240,如果推测线路上存在用户终端设备，反向供电设备通过指 示灯方式发出告警信号， 并且不能给配线设备供电， 这里的告警信号 用于提示用户切断用户终端。
其中， 如果测试线路上的电容值大于 luF, 那么反向供电设备就 发出告警信号， 这里的告警信号可以开启指示灯的方式， 也可以釆用 其他方式告警， 此时， 反向供电设备不给向配线设备供电， 用户接收 到告警信号后， 切断用户终端， 反向供电设备正常给配线设备供电。
S250 ,如果反向供电设备发现用户终端没有摘机，反向供电设备 则通过远程开关控制模块控制配线设备的开关闭合，反向供电设备控 制本地开关闭合， 给配线设备供电。
其中， 如果反向供电设备发送铃流信号一段时间后， 这里的一段 时间， 可以是一般情况下， 用户在听到电话铃声后， 去接听电话的合 理时间段， 最终没有摘机行为， 反向供电设备向配线设备供电。
S260 ,如果反向供电设备发现用户终端摘机， 则反向供电设备通 过发出告警信号， 这里的告警信号为提示用户切断该电话机， 切断之 前， 不能给配线设备供电。
在本步骤中，如果反向供电设备发送铃流信号后，用户终端摘机， 则反向供电设备发出告警信号， 这里的告警信号可以通过指示灯发 出， 还可以釆用其他方式， 此时， 反向供电设备不给配线设备供电。
通过以上技术方案，反向供电设备向线路上提供电力资源时， 通 过检测线路上是否存在用户终端， 一旦检测到有用户终端存在， 即产 生告警信号， 直到消除线路上的用户终端才正常供电， 避免了用户终 端被毁坏。
本发明实施例还提供了一种反向供电设备， 如图 3所示，反向供 电设备 300包含线路 310、远程开关控制模块 320、线路测试模块 330、 铃流发送和检测模块 340、 ***控制模块 350、 供电模块 360、 开关 S2 370 , 其中， 供电模块 360—端与开关 S2 370连接， 远程开关控制 模块 320—端与线路 310连接， 一端与***控制模块 350连接， 线路 测试模块 330—端与线路 310连接， 一端与***控制模块 350连接， 铃流发送和检测模块 340—端与线路 310连接，一端与***控制模块 350连接， 包括：

其中， 这里的临界值可以是： 如果是测试电容值， 可以参考 1微 法； 如果是测试电阻值， 可以参考 300欧姆。
铃流发送和检测模块 340 ,用于当线路测试模块 330推测线路 310 上不存在用户终端时， 向线路 310上发送铃流信号， 并检测线路 310 上终端是否有正在使用中； 如果经过一段合理时间后， 有用户应答所 述铃流信号， 则认为线路上存在用户终端， 此时， ***控制模块 350 发出告警信号， 并且反向供电设备不能向线路 310上提供电力； 如果 经过一段合理时间后， 没有用户应答所述铃流这里的铃流信号， 则认 为线路上不存在用户终端， 此时， 反向供电设备可以通过***控制模 块 350关闭开关 S2 370 ,并通过远程开关控制模块 320控制配线设备 的开关闭合，使得供电模块 360可以向配线设备提供电力资源，其中， 这里的一段合理时间， 可以是用户听到电话铃声， 通常接听电话的时 间； 这里的铃流信号可以是 25HZ。
***控制模块 350, 用于当所述线路测试模块确认所述线路上存 在所述用户终端时，发出告警信号； 还可以用于当铃流发送和检测模 块 340认为线路上不存在用户终端时， 控制开关 S2 370闭合， 使得 供电模块 360向线路 310上提供电力资源。
供电模块 360 , 用于向线路 310提供反向电压和电流。
开关 S2 370, 用于控制是否向线路 110上供电。
通过以上技术方案，反向供电设备向线路上提供电力资源时， 通 过检测线路上是否存在用户终端， 一旦检测到有用户终端存在， 即产 生告警信号， 直到消除线路上的用户终端才正常供电， 避免用户终端 被毁坏。
本发明实施例还提供了一种反向供电***， 如图 4所示，反向供 电***包括配线设备 ( Distribution Point Unit, 简称 DPU )和反向供 电设备 ( Power Supply Equipment, 简称 PSE ), DPU和 PSE通过双 绞线相连， DPU包括线路 310、 开关 S1 510、 业务模块 520、 取电模 块 530、开关上电控制电路 540, 其中， 业务模块一端连接在线路 310 上，取电模块一端连接在线路 310上， 开关上电控制电路 540—端与 开关 S1 510相连， 一端与线路 310相连， 用于控制开关 S1的开启或 者闭合， 同时， 开关上电控制电路 540受到反向供电设备 300的远程 开关控制模块 320的控制； PSE包括线路 310、远程开关控制模块 320、 线路测试模块 330、 铃流发送和检测模块 340、 ***控制模块 350、 供电模块 360、 开关 S2 370, 其中， 供电模块 360—端与开关 S2 370 连接， 远程开关控制模块 320—端与线路 310连接，一端与***控制 模块 350连接， 线路测试模块 330—端与线路 310连接， 一端与*** 控制模块 350连接， 铃流发送和检测模块 340—端与线路 310连接， 一端与***控制模块 350连接，下面结合具体的应用场景来进一步说 明反向供电***， 包括：
步骤一， DPU无供电， 开关 S1处于打开状态。
步骤二， PSE上电后， 开关 S2 370处于打开状态。
步骤三， PSE启动线路测试模块 330来判断线路 310上是否存在 用户终端， 如电话机。
步骤四， 如果通过测试， 发现存在用户终端， PSE通过***控制 模块 350发出告警信号， 并且不给 DPU供电， 直到用户切断了用户 终端电话机， ***控制模块 350控制开关 S2闭合， 并且通知远程开 关控制模块 320闭合开关 S1 520,反向供电设备 300正常供电， DPU 可以正常取电， 业务模块 520正常工作。
步骤五， 如果通过测试， 发现不存在用户终端， PSE再启动铃流 发送模块 340发送铃流信号， 发送一段时间后，检测该铃流信号是否 有用户响应， 即是否有用户接听电话， 如果有， 则认为线路 310上存 在用户终端， 按照步骤四的方式告警， 并且不给 DPU供电。
步骤六， 如果没有用户接听电话机， PSE通过远程开关控制模块 320来控制 DPU的开关 S1关闭， PSE控制开关 S2关闭， PSE正常 供电工作， DPU正常取电， 业务模块 520正常。 通过以上技术方案，反向供电设备向线路上提供电力资源时， 通 过检测线路上是否存在用户终端，一旦检测到有用户终端存在， 即产 生告警信号， 直到消除线路上的用户终端才正常供电， 避免了用户终 端被毁坏。
