图 7为本发明信息处理系统实施例的结构示意图。 具体实施方式 首先说明本发明实施例的信息处理方法和设备所应用的系统环境, 图 1 为本发明信息处理方法实施例应用的 FTT dp系统架构图, 如图 1所示, 在 FTT dp的系统架构中, 从局端到分线点设备都是釆用光纤传输, 而从分线点 设备到用户家庭内部是通过铜线传输, 该铜线例如是双绞线。
图 2为本图 1中的分线点设备与用户家庭内部的用户端设备的连接结构 图, 如图 2所示, 示出了分线点设备和用户端设备的各自结构、 以及两者之 间的连接。 其中, 用户端设备与用户侧的计算机连接, 该用户端设备可以包 括: DSL终端模块 11、功率整合器 12、供电模块 13和直流 /交流转换模块 14; 分线点设备包括: 功率检测器 21、 DSL局端模块 22。 用户端设备和分线点设 备通过双绞线 30连接。 此外, 所述的分线点设备还可以包括: 功率分离器、 直流模块和光纤传输模块等。
本实施例中, 分线点设备是由用户端设备进行反向供电提供电能, 具体 的,用户端设备通过直流 /交流转换模块 14将家庭内部的 220V交流电转换为 直流电, 然后通过供电模块 13和功率整合器 12将该直流电传递到双绞线 30 上, 由双绞线 30将直流电传输至分线点设备。 在分线点设备上, 功率分离器 将直流电分离给功率检测器 21 , 功率检测器 21可以对该直流电进行功率检 测, 并将直流电传递给直流模块, 由直流模块对 DSL局端模块 22、 光纤传输 模块进行供电。 DSL局端模块 22使用该供电与用户端设备中的 DSL终端模 块 11进行通信, 实现高速的数据传输。
本发明实施例所述的信息处理方法, 是分线点设备执行, 并且是用于说 明在反向供电时, 分线点设备接收到用户端设备供给的电能后, 根据该电能 所做的处理; 本发明实施例的信息处理设备是分线点设备。 详细说明如下: 实施例一
图 3为本发明信息处理方法一实施例的流程示意图, 本实施例的方法由 分线点设备执行, 并且结合图 2中所示的分线点设备的结构来描述本实施例 的处理方法; 如图 3所示, 该方法可以包括:
301、 接收用户端设备提供的供电电能;
其中, 分线点设备的功率分离器接收双绞线传输来的供电电能, 该供电 电能例如是由用户端设备反向供给来的直流电。 功率分离器将接收到的供电 电能发送至分线点设备中的功率检测器。
302、 检测所述供电电能的功率;
其中, 功率检测器检测供电电能的功率, 该功率指的是供电电能所能提 供的最大功率。 具体实施中, 功率检测器可以有多种方式检测供电电能所能 提供的最大功率, 例如, 可以检测该供电电能作用下的负载的电压和电流, 通过该电压和电流的乘积得到所述最大功率。
303、 根据所述供电电能的功率, 获取与所述功率相适应的数字用户线 DSL通信的工作参数;
其中, 功率检测器会将其检测到的供电电能所能提供的最大功率发送至 分线点设备中的 DSL局端模块, 该 DSL局端模块将根据该供电电能的功率, 获取与所述功率相适应的 DSL通信的工作参数。
DSL局端模块在与用户端设备的 DSL终端模块通信时,双方都釆用相同 的工作参数, 该工作参数例如是帧格式、 功率谱密度和数据传输速率等, 这 些工作参数是由 DSL局端模块确定并在 DSL激活过程中传递至 DSL终端模 块的。 用户端设备中的 DSL终端模块可以根据所述的工作参数, 调整其与 DSL局端模块通信时的帧格式、 数据传输速率等, 按照该工作参数规定的格 式与 DSL局端模块通信。
釆用不同的工作参数, 将使得 DSL局端模块的功耗不同, 相应的 DSL 局端模块对于供电电能的功率需求也不同; 例如, DSL局端模块确定的数据 传输速率越高, 其功耗就越大, 则就需要供电电能提供的功率也越大, 否则 如果供电电能提供的功率较低, 就不能满足 DSL局端模块正常工作的功耗需 求, 就可能导致分线点设备异常。
因此,本实施例中, DSL局端模块将根据实际检测到的供电电能的功率, 获取与所述功率相适应的工作参数。 这里所述的相适应指的是, 釆用所述的 工作参数进行通信所需要的功耗是能够由所述的供电电能的功率支持的, 比 如, 假设 DSL局端模块釆用某种工作参数, 其引起的功耗是 20w, 如果供电 电能的功率大于 20w例如是 22w , 则可以称为该供电电能的功率与所述工作 参数是相适应的; 而如果供电电能的功率小于 20w例如是 15w, 则此时该供 电电能的功率将不能支持 DSL局端模块的正常工作, 可能引起设备异常, 这 时其实供电电能的功率与所述工作参数是不相适应的。
304、 使用所述工作参数与用户端设备进行 DSL通信。
其中, 分线点设备的 DSL局端模块在确定与供电电能的功率相适应的工 作参数后, 后续将使用该工作参数与用户端设备的 DSL终端模块进行通信。 具体的, 分线点设备在启动时将接收到用户端设备反向供电的电能, DSL局 端模块根据该供电电能的功率确定工作参数后, 将开始执行与 DSL终端模块 之间的 DSL激活过程, 并在 DSL激活过程中的握手阶段、 信道训练阶段将 确定的工作参数传递至 DSL终端模块, 在正常数据收发阶段则 DSL局端模 块和 DSL终端模块双方将根据该工作参数执行数据通信。
需要说明的是, 本发明实施例所述的信息处理方法的执行, 可以是在分 线点设备启动时, 也可以是在分线点设备与用户端设备进行通信的过程中。 例如, 分线点设备启动时, 其接收反向供电的电能, 并进行上述的功率检测 以及工作参数的获取等处理; 又例如, 分线点设备在与用户端设备进行通信 的过程中, 可以设定一个检测周期, 周期性的检测供电电能的功率并根据检 测的功率更新使用的工作参数。 具体实施中, 分线点设备可以仅在设备启动 时执行本实施例的处理方法, 或者仅在通信过程中周期执行本实施例的处理 方法, 或者既在启动时执行也在通信过程中周期性执行。
本实施例的信息处理方法, 分线点设备是根据实际检测到的供电电能的 功率, 获取与所述功率相适应的工作参数, 因此, 能够使得分线点设备进行 数据通信时所使用的工作参数与供电电能提供的功率是匹配的, 供电电能能 够支持分线点设备的工作, 能够满足分线点设备的通信需求, 从而避免了分 线点设备由于供电功率不足而造成的设备故障。
实施例二
本实施例是对实施例一的信息处理方法的更详细的说明, 对分线点设备 所执行的每一处理步骤都进行具体的举例描述。 图 4为本发明信息处理方法 另一实施例的流程示意图, 如图 4所示, 该方法可以包括:
401、分线点设备启动,功率分离器接收用户端设备反向供电的供电电能; 其中, 用户端设备通过直流 /交流转换模块将家庭内部的 220V交流电转 换为直流电, 然后通过供电模块和功率整合器将该直流电传递到双绞线上, 由双绞线将直流电传输至分线点设备, 具体是由分线点设备中的功率分离器 接收该直流电; 本实施例将该直流电称为供电电能。
402、 功率分离器将接收到的供电电能发送至功率检测器;
403、 功率检测器检测该供电电能的功率;
其中, 功率检测器检测的所述功率是反向供电的供电电能提供的最大功 率。 具体实施中, 功率检测器可以釆用多种方式进行功率检测, 本实施例提 供了一种可选的检测功率的方法, 参见图 5所示, 图 5为本发明信息处理方 法另一实施例中的功率检测示意图。 图 5示出了功率分离器与功率检测器内 部结构的连接, 并且是仅仅示出了用于检测功率的部分电路结构, 实际在功 率检测器内可能还包括其他的功能单元或者结构, 但是在该图 5中未示出。
例如, 在该功率检测器内, 设置有负载 R、 开关 K1和 K2、 电压检测器、 电流检测器以及功率计算单元(该功率计算单元未示出)等; 功率分离器与 功率检测器连接, 实际上是将功率分离器连接到开关 K1和 Κ2, 功率检测器 通过控制开关 K1和 Κ2闭合, 将功率分离器与负载 R连接, 接通上述图 5 中所示的电路, 功率分离器提供的供电电能将在图 5所示的通路中存在, 负 载 R在该供电电能的作用下, 有电流经过并有电压存在。 本实施例通过电压 检测器检测负载 R两端的电压, 并通过电流检测器检测负载 R流经的电流。 此外, 功率检测器中的功率计算单元可以将上述检测得到的负载 R上的电压 和电流做乘积运算得到的即为供电电能的功率。 例如, 假设负载 R上的电压 是 V0, 电流是 10, 则供电电能的功率即为 P= V0* I0。
404、 功率检测器将检测到的供电电能的功率发送至 DSL局端模块; 其中, 本实施例所述的 DSL局端模块相当于局端的 xDSL收发器, 主要 用于对数据进行调制解调处理、 以及将处理后的数据发送至线路中或者从线 路中分离出要处理的数据,该 DSL局端模块中包括 DSL调制解调器,该 DSL 调制解调器负责数据的调制解调处理。 本实施例的功率检测器将检测到的供 电电能的功率实际上是发送至 DSL局端模块的 DSL调制解调器。
本实施例中, 功率检测器将检测到的供电电能的功率发送至 DSL局端模 块的方式可以有多种, 例如, 功率检测器可以将检测到的功率发送至直流模 块, 再由直流模块传递至 DSL局端模块; 或者, 如图 2中的虚线所示, 功率 检测器可以直接将检测到的功率发送至 DSL局端模块。
405、 DSL局端模块根据供电电能的功率,获取与功率相适应的工作参数; 其中, 本实施例提供如下一种可选的工作参数的获取方式:
首先, 在获取与所述功率相适应的工作参数之前, 具体可以是在接收到 供电电能之前, 预先存储至少两个参考功率、 以及与所述两个参考功率分别 对应的工作参数;
具体的, DSL局端模块的功耗是与很多因素有关的, 在本实施例中可以 选择对 DSL局端模块的功耗影响较大的几个工作参数, 本实施例选择了三个 工作参数,分别为帧格式参数(例如,在每个帧中有几个子帧用于传输数据 )、 信号发送的功率语密度( Power Spectrum Density, 简称: PSD ) 、 以及数据 传输峰值速率(即最大收发数据速率) ; 当然, 具体实施中, 也可以选择其 他参数, 也可以变更选择的工作参数的数量例如选择四个参数等。 本实施例 建立的是釆用某个特定值的工作参数时, DSL局端模块的功耗与该工作参数 的对应关系, 所述 DSL局端模块的功耗釆用 DSL局端模块的峰值功率, 并 将该峰值功率称为参考功率。 参见如下的表 1所示:
Figure imgf000009_0001
峰值功率 PI PSD 1
帧格式参数 1
数据传输峰值速率 1
峰值功率 P2 PSD 2
帧格式参数 2
数据传输峰值速率 2
峰值功率 P3 PSD 3
帧格式参数 3
数据传输峰值速率 3
其他(低于 P3 ) 不能激活 如表 1所示, 本实施例预先在 DSL局端模块中存储了三个参考功率, 相 当于三个等级的参考功率, 假设峰值功率 Pl 值功率 P2>峰值功率 P3; 并 且存储了与每个等级的参考功率分别对应的工作参数, 本实施例是上述的三 个工作参数, 即釆用某个等级的工作参数, DSL局端模块的功耗就是表 1中 该工作参数对应的峰值功率。
上述的与参考功率对应的工作参数的取值的确定, 是根据工作参数与功 耗的关系来执行的。 例如, DSL局端模块根据其每秒处理 DSL符号数与功耗 的关系, 来决定对应某个参考功率的帧格式参数, 每秒处理的 DSL符号数越 多功耗越大, 则参考功率值增大时可以将帧格式参数设置为每帧中的承载数 据的子帧数越多; 又例如, DSL局端模块根据用户速率带宽与功耗的关系, 来决定对应某个参考功率的数据传输峰值速率, 通常用户速率带宽越大功耗 越大, 则参考功率值增大时可以相应增加数据传输峰值速率; 再例如, 可以 根据 DSL信号带宽、 信号的总功率与功耗的关系, 来决定对应某个参考功率 的 PSD等。 还可以结合考虑数字前端 (Digital Front End, 简称: DFE)和模拟 前端 (Analog Front End, 简称: AFE)的静态功耗设置某个等级的参考功率。
此外, 在设置与参考功率对应的工作参数的取值时, 在保持一定的参考 功率值不变的条件下,本实施例的上述三个工作参数可以按照一定的优先级, 优先满足某个工作参数取值的最大化。 比如, 如果分线点设备与用户端设备 之间的距离较长, 数据需要传输较远的距离, 则优先使得 PSD的值尽量大, 因为较大的 PSD有利于将数据传输较远的距离; 或者, 如果分线点设备与用 户端设备之间的距离较短, 可以优先使得帧格式参数尽量大, 提高数据传输 的效率。
进一步的, 由表 1中还可以看到, 在所列举的三个等级的参考功率之外, 还示出了一种情况, 即当供电电能的功率低于峰值功率 P3时, DSL局端模块 将不能执行 DSL激活流程, 即无法正常工作, 不能与 DSL终端模块通信。 此时, 实际是相当于将峰值功率 P3作为一个阈值, 只有不低于该阈值的功率 才能保证 DSL局端模块的正常通信, 这样可以更加有效的避免 DSL局端模 块由于供电功率不足而导致的设备异常。
接着, DSL局端模块将接收到的供电电能的功率, 与存储的至少两个参 考功率例如上述表 i中的三个等级的参考功率进行比较, 确定小于或等于所 述供电电能的功率的最大的参考功率。
例如, 设峰值功率 Pl 值功率 P2>峰值功率 P3 , 并且, 供电电能的 功率的值是位于 P1和 P2之间, 即峰值功率 Pl>供电电能的功率>峰值功率 P2, 则小于或等于所述供电电能的功率的最大的参考功率就是 P2。
然后, DSL局端模块将确定的所述最大的参考功率对应的工作参数, 作 为与所述供电电能的功率相适应的工作参数。 比如, 上述的例子中, 所述最 大的参考功率是 P2, 则将表 1中的与 P2对应的工作参数作为与所述供电电 能的功率相适应的工作参数即可, 即表 1中的 PSD 2、 帧格式参数 2和数据 传输峰值速率 2。
此外,如果在将所述供电电能的功率与表 1中的参考功率进行比较之后, 发现所述供电电能的功率小于表 1中的任何一个参考功率, 比如, 峰值功率 Pl 值功率 P2>峰值功率 P3的情况下, 供电电能的功率小于 P3 , 则 DSL 局端模块将不再执行后续的 DSL激活流程, 不再与用户端设备进行通信, 因 为此时供电电能的功率较低, 无法满足 DSL局端模块正常工作的功率需求, 这样可以更加有效避免 DSL局端模块由于供电功率不足而导致的设备异常。
上述提供的 DSL局端模块执行的工作参数的获取方式, 实际上是相当于 根据预先存储的工作参数与参考功率的对应关系模板(即表 1 ) , 来确定与 供电电能的功率相适应的工作参数。 可选的, 具体实施中, DSL局端模块也 可以实时计算, 比如可以在接收到供电电能的功率时, 再根据该功率、 以及 工作参数与功耗的关系, 实时计算得到与所述功率相适应的工作参数。
406、 DSL局端模块执行 DSL激活流程, 并在该激活流程中将确定的工 作参数发送至 DSL终端模块;
其中, DSL激活流程包括: G.994.1握手阶段、 信道训练阶段和正常数据 收发阶段; 在 G.994. 1与信道训练阶段, DSL局端模块与 DSL终端模块将交 互工作参数, 此时, DSL局端模块会将在 405中获取的工作参数传递给 DSL 终端模块。本实施例中, DSL局端模块可以釆用时分复用-正交频分独用(Time domain duplex- Orthogonal Frequency Division Multiplexing,简称: TDD-OFDM) 作为调制解调技术, 在信道训练阶段将开始发送 TDD-OFDM信号。
本实施例的方案中, 是以分线点设备在启动时, 执行上述的功率检测和 工作参数的获取等处理, 具体实施中, DSL局端模块也可以在与用户端设备 的 DSL终端模块的通信过程中, 周期性检测反向供电能提供的最大功率, 并 根据检测到功率调整自己的工作参数。 比如, 在 DSL局端模块与 DSL终端 模块通信过程中, 可能由于某种原因导致供电电能的功率下降, 此时, 分线 点设备的功率检测器在根据预设周期周期性检测供电电能的功率时, 将得到 最新的即变化后的供电功率, 并发送至 DSL局端模块; DSL局端模块将会根 据功率的变化实时调整与该功率相适应的工作参数, 并将最新的工作参数发 送至 DSL终端模块, 使得 DSL终端模块也更新自身侧的工作参数, 分线点 设备和用户端设备后续将按照该更新的工作参数进行通信。 其中, 周期性检 测时的预设周期的时间本实施例不做限制,可以根据实际应用需求具体设定。
本实施例的信息处理方法, 通过使用与供电电能的功率相适应的工作参 功耗的作用, 不会盲目的釆用超出供电功率负荷的工作参数。
407、 分线点设备与用户端设备使用所述工作参数正常通信。
