Description

唤醒远端设备的方法和系统 技术领域
本发明属于控制远端设备功耗的方法和系统， 尤其是一种通过线缆唤醒远端设备的方 法和系统。
背景技术
普通固定电话系统具有远程唤醒和状态检测的能力， 即局端设备可以通过双绞线远程 唤醒终端设备并检测终端状态。
图 1显示了一个普通电话系统用户网络接口部分的框图，包括局端接口设备 1、 电话机 2和连接局端接口设备与电话机的双绞线 3，其中局端接口设备 1又由话音收发模块 11、供 电和监测模块 12、铃流发生器模块 13、变压器 14和 15等组成，电话机由话音处理模块 21、 稳压电源模块 22、 振铃模块 23、 叉簧开关 24、 整流模块 25以及外接于端口 E的耳机和外 接于端口 M的麦克风组成。
根据 GB-T 15279规范， 在挂机状态下， 电话机 2的叉簧开关 24处于断开的状态， 电 话机的漏电电流应小于 25微安， 局端接口设备 1输出的馈电电压为直流 48伏； 在取机状 态下，叉簧开关 24处于闭合状态， 电话机的直流电阻小于 350欧姆，正常工作耗电约 18-60 毫安。 供电和监测模块 12通过检测馈电电流， 判断出电话机已处于取机活动状态后， 一方 面将该活动状态通过端口 W送至局端其他模块进一步处理， 另一方面将自身馈电输出电压 调整到 10伏左右。 支持远程计费指示的供电和监测模块 12还具有交换馈电电压极性的功 能， 在建立通话连接以后， 可以根据馈电控制端口〗的指示， 将在双绞线 3上输出的馈电 电压正负极性对调。
在局端接口设备 1中设置有铃流发生器模块 13， 在电话机 2中设有振铃模块 23。 为了 通知电话被叫用户有来话到达， 铃流发生器模块 13用输入电压 VR产生一个约 90伏 25赫 兹的交流电压， 通过变压器 14和 15输出到电话双绞线 3， 再经过双绞线 3施加到电话机 2 中的振铃模块 23， 使振铃模块 23响铃。 铃流发生器模块 13以工作 1秒停 4秒的间歇方式 产生铃流电压。在铃流发生器模块 13输出铃流电压的 1秒钟期间，暂停供电和监测模块 12 的馈电电压输出和馈电电流检测； 在铃流发生器模块 13停止输出铃流电压的 4秒钟期间， 启用供电和监测模块 12的馈电电压输出和馈电电流检测。
当电话用户打电话时， 人工闭合叉簧开关 24， 电话机 2中更多的电路模块开始工作消 耗电流， 导致流经电话双绞线 3的馈电电流大增， 供电和监测模块 12通过检测馈电电流， 判断出电话机 2处于取机活动状态。
模拟电话系统的上述唤醒方法需要单独提供的铃流发生装置， 并且存在与摘挂机电流 检测系统存在冲突， 系统结构相当复杂。 而且使用 90伏交流铃流的响铃方式耗电大、 成本 高， 不符合节能环保的要求， 应当予以取消。
信息时代普通电话正逐渐被数字用户线调制解调器所取代。 人们希望 DSL调制解调器 也能够像普通电话那样， 可以仅依靠局端远程供电工作； 在没有数据需要传输时进入几乎 不耗能的休眠状态； 在本地有数据需要发送时主动自举进入工作状态， 在被其它网络设备 呼叫时由局端设备唤醒进入工作状态。
然而普通电话的唤醒和呼叫方式适合于人的操作，不适合 DSL调制解调器的工作方式。 对于挂接了多个设备的电话线， 人可以保证只有唯一设备在线工作， 而 DSL调制解调器设 备无法保证。 如果同一条电话线上有两台设备同时主动启动工作， 或因为同时收到被叫信 号而启动工作， DSL调制解调器通常都不能正常建立连接。 目前公开的其它远程唤醒的技术， 均与远程唤醒计算机相关。 这些唤醒方法要求计算 机安装了可提供额外休眠电源的机箱电源， 以及支持远程唤醒的主板和网卡。 实际上所有 机箱电源、 电脑主板和网卡均处于带电工作状态， 只是因为关闭了耗能较高的部分功能而 使工作电流大幅度下降， 并非真正整台电脑都不耗电能的断电状态。
此外智能家庭或办公场所， 也存在某些设备需要远程唤醒供电的情况。 如用于间歇监 控的摄像头、 智能照明灯具等。 目前这些设备只能人工启动， 或者一直开机供电， 还不能 实现远程唤醒。
本发明拟解决或改善上述公开的某些问题之一。

本发明的有益效果：
1. 唤醒能耗低
采用 90伏铃流馈电的传统振铃唤醒方式，振铃期间局端需要提供超过 1瓦的铃流功率。 这对于端口密度较高的局端设备而言， 功耗与散热都是一种挑战， 限制了集成度的进一步 提高。 而采用本发明的远程唤醒方式， 所需功率不超过数毫瓦， 在不影响原有唤醒能力的 前提下大大降低了局端能耗和热设计难度， 符合低碳经济的趋势。
2. 降低了耐压工艺要求
本发明完全取消了高达 90伏交流电压的铃流发生器模块，整个系统的最高工作电压降 低了到正常工作所必须提供的额定直流电压， 对系统漏触电安全和耐压工艺要求都大为降 低， 便于系统向更广阔领域的应用和系统自身集成度的进一步提高。
3. 可唤醒真正休眠的系统 本发明的一种实施方案通过产生和识别反极性电压信号， 实现对远端设备的唤醒。远端设 备可以处于完全切断电源的状态： 在被唤醒时， 只需要对唤醒信号进行整流， 就可以获得唤醒 供电模块工作所需的电能， 也可以依靠唤醒信号电压提供电源功率。避免了目前依靠信令信号 实现唤醒的网卡和调制解调器唤醒方法， 均需要设备提供一定功率的维持电源的情况。
4. 应用范围广， 易于实施
本发明所公开的产生和识别反极性电压信号都是简单方法， 产生唤醒信号的一种实施 方案仅需一个双刀双掷开关即可， 识别唤醒信号的一种实施方案也仅需要一支二极管， 易 于实施。 整个唤醒系统仅包括唤醒信号发生装置、 远端设备供电装置和唤醒信号馈线， 不 涉及远端设备的特殊应用，几乎任何需要远程唤醒并可以提供有线连接的场合均可以应用， 具有广泛的应用前景。

具体实施方式
下面描述本发明的具体实施例。 为了提供这些实施例的简明描述， 本文件中未描述实际实 现方案的所有特征。 应当认识到， 在任何实际实现方案的开发过程中， 可能还必须做出一些针 对特定应用的其它具体决定， 以符合与特定系统和业务相关的约束条件。 对于受益于本公开内 容的普通技术人员而言， 这些可能复杂而耗时的具体决定只是设计、 制造和生产的常规任务。 第一实施例
本实施例是一种以反极性直流电压作为唤醒信号的远程唤醒系统和方法。
在本实施例中， 远程唤醒系统包括： "唤醒信号发生装置 4"、 "远端设备供电装置 5 " 和连接 "唤醒信号发生装置 4"与 "远端设备供电装置 5 " 的 "唤醒信号馈线 6"。
"唤醒信号发生装置 4"用以产生包括唤醒信号、常态信号和占用信号在内的不同特性 的电压信号， 并通过 "唤醒信号馈线 6"送达 "远端设备供电装置 5 "。
"远端设备供电装置 5 "用以在休眠的情况下被远程唤醒而产生本地电源供电输出， 并 通过 "唤醒信号馈线 6"将远端设备供电状态信号反馈给 "唤醒信号发生装置 4"。
"唤醒信号发生装置 4"还同时通过检测输出到 "唤醒信号馈线"中的馈线电流， 并在 馈线电流超过规定阈值时判定远端设备已经处于被唤醒的工作状态。 "唤醒信号发生装置 4"可以是一个单独的设备， 也可以是其它设备中的一部分， 类似 于普通模拟电话局端接口设备中的供电和监测模块 12。
"唤醒信号发生装置 4"与 "唤醒信号馈线 6"的连接可以是直接的连接， 如图 2所示， 也可以是通过某种中间装置的耦合连接。如图 3、图 4、图 5中所示， "唤醒信号发生装置 4" 分别以不同的方式经过变压器耦合连接到 "唤醒信号馈线 "。
用于连接 "唤醒信号发生装置 4"与 "远端设备供电装置 5"， 并传递 "唤醒信号发生 装置 4"所产生的唤醒信号和 "远端设备供电装置 5"所产生的供电状态信号的 "唤醒信号 馈线 6"， 可以是多种形式的导电线缆。
最简单的 "唤醒信号馈线 6"实现方式是两根平行导线。 图 3、 图 4和图 5分别给出了 "唤醒信号馈线 6"采用一对双绞线 6A、 一对双绞线 6B1加一根导线 6B2， 和 6C1加 6C2 两对双绞线的不同实施例。 对于低频等效电路而言， 由于所述连接方法的耦合变压器对于 传输唤醒信号和供电状态信号而言相当于串联电阻， 双绞线等效于单根直导线， 实施例所 给出的唤醒信号馈线实施方案在电路原理上与图 2中的两根平行导线是等价的。
"远端设备供电装置 5"在休眠状态下不消耗电流， 因此 "唤醒信号馈线"上没有电流或 只存在极小的泄漏电流。 而一旦 "远端设备供电装置 5"被唤醒进入正常工作状态， "唤醒信 号馈线 "中可以承载一个较大的电流， 作为供电状态信号指示。 当馈线电流小于某个规定阈值 时， 例如小于 2毫安时， 可以认为 "远端设备供电装置"处于休眠状态； 而当馈线电流大于某 个规定阈值时， 例如大于 5毫安时， 可以认为 "远端设备供电装置" 已经处于正常工作状态。
如果规定的判定处于休眠状态和判定处于工作状态的两个阈值不同， 那么可能存在重 叠或未定义的状态。 例如当规定馈线电流小于 2毫安为休眠状态， 馈线电流大于 5毫安为 正常工作状态， 则馈线电流处于 2毫安至 5毫安之间时即为未定义状态。 通常未定义状态 出现于将 "唤醒信号馈线"作为总线， 挂接了过多设备时的情况。 多个设备较小的泄漏电 流叠加以后可能会比较大。 减少同时挂接工作的设备， 或縮减判定休眠和判定工作两种状 态而规定的两个阈值的差距， 可以减少或消除出现未定义状态的概率。
"远端设备供电装置 5"正常工作时为远端设备提供工作电源。 输出的电源可以是单一电 压的直流电源， 也可以是多种电压值的稳压或不稳压的直流电源， 甚至可以提供交流电源。 图 2中给出的供电电压输出端口只是表明输出电源电压的位置，并不是指只能输出一种电源电压。
"远端设备供电装置 5"与 "唤醒信号馈线 6"的连接也可以有多种变形形式， 分别如 图 2所示的直接相连和图 3、 图 4和图 5所示的耦合连接方式。
本实施例中的所述的唤醒信号是与常态信号极性相反的直流电压。 如果规定在远端设 备没有正常工作时唤醒信号馈线上施加了指定极性的直流电压， 并称此直流电压为常态信 号， 那么可以规定唤醒信号是与常态信号极性相反的直流电压。
为了帮助实施所述的 "唤醒信号发生装置"和 "远端设备供电装置"， 本实施例中的 "唤 醒信号发生装置 4"包括了： 输入供电端口 VB、 唤醒控制端口 G、 远端状态输出端口 S、 馈线 输出端口 61、 电源模块 41、 电流检测模块 42和唤醒信号发生模块 43。 "远端设备供电装置 5" 包括了： 唤醒馈线端口 62、 唤醒信号检测模块 53、 可控电源模块 51和供电电压输出端口 V。
所述的 "电源模块 41 "从输入供电端口 VB取得电能， 经过变换以后输出给 "唤醒信 号发生装置" 中的其他模块使用。
电源模块 41可以输出多种电源电压， 并且可以是交流输入交流输出、 交流输入直流输 出、 直流输入交流输出和直流输入直流输出等多种实施方案。 所有这些实施方法市场上均 有成熟产品可以选用。
例如德州仪器公司的标准隔离型直流到直流变换系列稳压电源就可以用 PT4141 产生 3.3伏电压输出， PT4142产生 5伏电压输出， PT4244产生 12伏电压输出， PT4564产生 15 伏电压输出。 此外深圳华达艾诺斯电源有限公司、 北京惠泽伟业公司、 上海意泽电气有限 公司等许多公司都提供 48伏标准通信电源模块和其他多种型号的直流稳压电源模块。
对于采用稳定的电池供电的系统， 电源模块甚至可以是图 6 所示的简单直导线连接 411。对于采用交流输入交流输出的电源模块，则可以采用图 7所示的抽头输出变压器实现， 也可以是市售的其他标准交流调压模块或变频调压设备。
所述的 "唤醒信号发生模块 43"根据 "唤醒控制端口 G" 的指示， 向 "馈线输出端口 61 "输出与常态信号极性相反的直流电压唤醒信号。 "唤醒信号发生模块 43"可以用双刀双 掷的开关 K1或继电器来实现，如图 8所示。唤醒信号发生模块 431包括了一个双刀双掷的 开关 Kl， 它可以是一个继电器的受控开关部分， 将输入电压 VI控制变换成需要的极性输 出。输出端 V+和 V-不是表示输出电压的极性，而是仅表示在常态信号状态下输出电压的两 个不同极性。 唤醒信号发生器模块 43也可以采用一个全桥驱动电路实现。 例如采用美国国 家半导体公司生产的 LMD18245、 荷兰恩智普公司生产的 UBA2036、 以及 Allegro公司生 产的 A3959等市售成熟芯片， 均可以方便地实现根据唤醒控制端口 G的指示来控制输出不 同极性的直流电压唤醒信号， 具体电路见相关芯片手册中的推荐参考设计。
定义占用信号是与常态信号极性相反的直流电压， 唤醒信号发生模块 43还需要在收到 外部控制信号时产生并输出占用信号。
所述的 "电流检测模块 42"可以是一个电流表； 也可以是如图 8中所示的直流电流检 测模块 421或者如图 9中所示的交流电流检测模块 422; 也可以是如图 10所示的电流检测 模块 423， 包括光耦元件 4231和 4232， Vp接正电源， 由电源模块 41提供； 还可以由市售 成熟芯片来实现， 如凌力尔特公司的 LT2940芯片， 具体电路可以参考相关芯片手册中的说 明和推荐参考设计。 电流检测模块 42的具体位置可以根据自身的性质设置， 例如直流电流 检测模块应放置在 "电源模块 41 "与 "唤醒信号发生模块 43"之间， 交流电流检测模块放 在 "电源模块 41 "与 "唤醒信号发生模块 43"之间或 "唤醒信号发生模块 43"之后。
所述的 "唤醒信号检测模块 53"在感知到唤醒信号时能产生并输出唤醒指示， 使 "可 控电源模块 51 "能够取得电能而进入正常工作状态， 向本地设备输出稳定的电源电压。
"唤醒信号检测模块 53"可以由如图 11所示的唤醒信号检测模块 531实现。当输入常 态信号时， 由于串联的二极管 D1和 D2反向截止， 唤醒信号检测模块 531在输出端无法提 供有效的唤醒指示。 当输入电压极性反转的唤醒信号时， 二极管 D1和 D2均导通， 反极性 的唤醒信号电压经过电阻 R1和 R2分压， 然后经过二极管 D3输出， 可作为控制可控电源 模块 51的使能信号。
"唤醒信号检测模块 53"也可以由图 12所示的唤醒信号检测模块 532实现。当输入常 态信号时， 由于二极管 D4反向截止， 场效应管也截止， 电阻 R5输出高电平， 表示没有唤 醒信号到达。 当输入唤醒信号时， 二极管 D4 导通， 场效应管也导通， 唤醒信号检测模块 532输出低电平信号， 该信号可作为控制可控电源模块 51的使能信号。
"唤醒信号检测模块 53"还可以由图 13所示的带记忆能力的唤醒信号检测模块 533 来实现。唤醒信号检测模块 533包括了一个常规的唤醒信号检测模块 5331和一个智能处理 模块 5332。 所述的常规唤醒信号检测模块 5331可以是图 11所示唤醒信号检测模块 531， 也可以是图 12所示的唤醒信号检测模块 532。智能处理模块 5332可以用纯数字逻辑器件来 设计， 可以使用现场可编程门阵列 FPGA实现， 也可以使用诸如 51单片机或 ARM嵌入式 智能芯片实现。 当常规唤醒信号检测模块 5331检测到唤醒信号并输出指示后， 智能处理模 块 5332可以记忆唤醒信号一段时间， 并在记忆有效时间范围内持续输出。
所述的 "可控电源模块 51 "可以是从唤醒信号馈线上取得电能的远程供电可控电源模 块， 也可以是直接从本地取得电能的本地供电可控电源模块。
对于远程供电可控电源模块而言， 可控电源模块 51可以是如图 14所示的可控电源模 块 511。 优选实施例可控电源模块 511包括了输入滤波电路 （Cl、 Ll、 L2和 C2)、 集成稳 压电路 （LM2575HV、 L3和 D511 ) 和输出滤波电路 （C3) 三部分电路。 所述的可控电源 模块 511在收到唤醒信号检测模块 53输出的低电平有效唤醒指示信号时， 从唤醒信号馈线 上取得电能， 经变换后稳压输出， 为本地需电设备提供出稳定的直流电压。 此时可控电源 模块 511消耗较大的电流， 并将此电流作为供电状态信号通过唤醒馈线端口输出。
优选实施例可控电源模块 511 中选用了带有使能控制的稳压集成电路芯片 LM2575HV。 更多更典型的直流稳压电源可能没有使能控制端口。 这时可以采用图 15所示 的可控电源模块 512。为了使可控电源模块在收到唤醒指示后能持续地取得电能，在输入端 串联了单向可控硅 D512。 当可控硅的输入端输入正向触发电压时， 可控硅导通， 稳压电路 5121工作，输出稳定的直流电压。稳压电路 5121可以是任何一种市售的成熟稳压电源模块。
由于唤醒信号馈线上的电压极性有可能翻转， 稳压电源模块应该在其输入部分串联一 个整流模块， 以保证直流稳压电源模块正常工作所需的输入电源极性。
除了美国国家半导体公司生产的 LM2575HV外， 上海爱立信公司生产的 PKM5000D、 摩托罗拉公司生产的 A78S40、 POWER公司生产的 TNY268、安森美公司生产的 NCP3063 等市售成熟芯片均可用于实现可控电源模块 51， 具体电路可以参考相关芯片手册中的说明 和推荐参考设计。
对于采用本地供电方式的可控电源模块而言， 可控电源模块 51可以用如图 16所示的 可控电源模块 513来实现。 该模块带有本地电源输入端口 VL， 并从本地电源输入端口 VL 取得电能。 可控电源模块 513在收到唤醒信号检测模块 53的唤醒指示后， 从本地电源输入 端口 VL取得电能， 经变换后稳压输出， 为本地需电设备提供稳定的直流电压。
为了向唤醒信号发生装置反馈远端设备工作状态， 采用本地供电的可控电源模块 513 需要增加一个远端设备工作状态信号发生模块 5132。 优选的远端工作状态信号发生模块是 一个继电器， 其接法示于图 16。 图 16中的稳压电源模块 5131可以是可控电源模块 511或 可控电源模块 512。
当稳压电源模块 5131 正常工作输出电压时， 作为远端设备工作状态信号发生器模块 5132的继电器吸合， 为 "唤醒信号馈线 6"提供电流回路， 产生用作远端设备供电状态指 示的馈线电流。 当稳压电源模块处于休眠状态而无电压输出时， 继电器控制端的绕阻无电 流通过， 受控端的开关断开， 此时 "唤醒信号线 6" 中无电流。
在初态情况下， 所有远端设备供电装置处于休眠状态， 唤醒信号发生装置 4输出常态 信号， 唤醒信号馈线 6中无电流， 唤醒信号发生装置 4检测到唤醒信号馈线 6中的电流小 于预设阈值， 判断出远端设备处于休眠状态， 并通过远端状态输出端口 S输出。
"唤醒信号发生模块 4"可产生与常态信号极性相反的直流电压唤醒信号， 唤醒连接在 唤醒信号馈线 6上的远端设备供电装置。 可分为两种情况：
第一种情况，连接在"唤醒信号馈线 6"上的所有远端设备供电装置在收到唤醒信号时， 被即时唤醒。 具体可用三个步骤完成。
