Description

单板运行状态的监控方法及装置 技术领域 本发明涉及通讯领域， 尤其涉及一种单板运行状态的监控方法及装置。 背景技术 目前， 无线通信的系列基站越来越多地使用微型电信计算架构 （Micro
Telecom Computing Architecture, 简称为 uTCA ), 使用主控板和受控板间的 相互协调来进行通信工作。 在无线通信系统的基站系统中， 监控基站的整个 运行过程是至关重要的。 对运行过程进行监控可以最大程度地掌握单板及系 统状况， 给技术人员和用户提供故障解决依据。 当有部分单板出现故障， 如 上电后不工作， 系统无法正常加载等情况时， 需要了解单板运行到何种程度， 问题出在哪一步的执行上。 因此， 在系统运行中， 尽早、 尽最大程度地对单 板的运行状态进行监控对系统维护具有重要意义。 才艮据现有技术， 记录单板的上电运行状态是在系统初始化后， 通过监控 进程进行监控， 例如： 使用黑匣子技术或单板告警来记录。 但是这些技术都 是在单板上电成功后， 基于操作系统之上或利用操作系统的功能来进行的， 而当单板在上电过程中就出现故障， 上电初始化未完成不能进入操作系统时 这些监控手段就不起作用。 单板上电故障中断， 其他监控手段所依赖的一些 工具或设备还未来得及初始化， 监控机制本身未建立起来， 对这段时间的单 板运行状况无法监控。 系统自身结构简单， 环境资源不够， 不足以提供一些 诸如网口等通信方式时， 监控也艮困难。 同时在 uTCA架构下， 受控板均通 过网口进行信息上报， 一旦网口出现异常， 将导致所有信息均上报失败。 因此， 为更全面地监控系统单板的运行过程， 必须从单板上电时起就进 行监控， 但是， 现有技术对此尚未提出有效地解决方案。 发明内容 考虑到现有技术对单板监控不全面的问题而 #丈出本发明， 为此， 本发明 的主要目的在于提供一种单板运行状态的监控方法及装置， 以解决现有技术 中的上述问题。 根据本发明的一个方面， 提供了一种单板运行状态的监控方法。 根据本发明的方法包括： 受控板上电时建立其与主控板之间的模块管理 控制器 MMC通信通道； 受控板通过 MMC通信通道， 居预先设置的一个 或多个监控信息点向主控板上报受控板的运行状态信息。 优选地， 受控板通过 MMC通信通道向主控板上报受控板的运行状态信 息， 进一步包括： 受控板向 MMC发送受控板的运行状态信息； MMC通过 智能平台管理接口 IPMI通道向主控板转发受控板的运行状态信息。 优选地， 受控板向 MMC发送受控板的运行状态信息， 进一步包括： 受 控板与 MMC通信的串口未完成初始化时， 通过写 CPU串口寄存器向 MMC 发送运行状态信息； 受控板与 MMC通信的串口已完成初始化时， 通过调用 标准写接口向 MMC发送运行^！ 态信息。 优选地， 受控板向 MMC发送受控板运行状态信息时， 增加预设延时； 和 /或受控板的运行状态信息小于 20字节。 优选地， 监控信息点用以表示受控板的运行阶段的运行状态， 其中， 运 行阶段包括以下至少之一： 汇编代码运行阶段、 小系统运行阶段、 引导应用 程序执行阶段、 单板控制运行阶段、 上层应用运行阶段。 根据本发明的另一方面， 还提供了一种单板运行状态的监控装置。 根据本发明的装置包括： 建立模块， 用于受控板上电时建立其与主控板 之间的 MMC通信通道； 上 4艮模块， 用于通过 MMC通信通道， 才艮据预先设 置的一个或多个监控信息点向主控板上报受控板的运行状态信息。 优选地， 上 4艮模块进一步包括： 第一上 4艮子模块， 用于向 MMC发送受 控板的运行状态信息； 第二上 4艮子模块， 用于 MMC通过 IPMI通道向主控 板转发受控板的运行状态信息。 优选地,第一上报子模块通过写 CPU串口寄存器或者通过调用标准写接 口向 MMC发送运行状态信息。 优选地， 该装置进一步包括： 设置模块， 用于预先设置一个或多个监控 信息点， 其中， 监控信息点用以表示受控板的运行阶段的运行状态， 运行阶 段包括以下至少之一： 汇编代码运行阶段、 小系统运行阶段、 引导应用程序 执行阶段、 单板控制运行阶段、 上层应用运行阶段。 才艮据本发明的上述技术方案， 通过 uTCA架构的 MMC的功能通道， 受 控板向主控板上 4艮从上电时刻起到系统稳定运行的工作过程的运行状态， 解 决了现有技术中对单板进行监控不全面的问题， 能够完整地记录受控板的运 行状态， 使得在常规监控手段无效情况下依旧可以收集受控板的运行状态， 对于系统的维护和故障解决具有重要的参考价值。 附图说明 此处所说明的附图用来提供对本发明的进一步理解， 构成本申请的一部 分， 本发明的示意性实施例及其说明用于解释本发明， 并不构成对本发明的 不当限定。 在附图中： 图 1是根据本发明实施例的单板运行状态的监控方法的流程图； 图 2是根据本发明实施例的主控板与受控板的框架架构示意图； 图 3是根据本发明实施例的单板运行状态的监控方法的优选处理方案的 流程图； 图 4是根据本发明实施例的单板运行阶段的流程图； 图 5是根据本发明实施例的 MMC通信流程图； 图 6是根据本发明系统实施例的单板运行状态的监控装置的框图； 图 7是根据本发明系统实施例的单板运行状态的监控装置的优选结构的 框图。 具体实施方式 本发明的主要思想主要在于： 利用 uTCA 架构下的模块管理控制器 ( Module Management Controller, 简称为 MMC ) 的功能通道， 受控板向主 控板上报从上电时刻起到系统稳定运行的工作过程的运行状态， 解决了现有 技术中对单板监控的不全面的问题， 通过本发明， 能够完整地记录受控板的 运行状态， 对系统的维护和故障解决具有重要的参考价值。 需要说明， 本发 明不仅适用于码分多址数字无线技术 ( Code-Division Multiple Access, 简称 为 CDMA ) 的基站系统， 也适合其他通信体制的无线通信基站系统， 例如： 全 3求 波接入互操作生 ( World Interoperability for Microwave Access, 简称为 WiMAX )、 时分同步码分多址技术 （Time Division-Synchronous CDMA, 简 称为 TD-SCDMA )、宽带码分多址技术（ Wideband CDMA,简称为 WCDMA )、 全球移动通讯系统（ Global System for Mobile Communications , 简称为 GSM ) 等。 为使本发明的目的、 技术方案和优点更加清楚， 以下结合附图及具体实 施例， 对本发明作进一步地详细说明。 方法实施例 根据本发明的实施例， 提出了一种单板运行状态的监控方法。 图 1是根 据本发明实施例的单板运行状态的监控方法的流程图， 如图 1所示， 该方法 包括： 步 4聚 S 102, 受控板上电时建立其与主控板之间的 MMC通信通道； 步骤 S 104, 受控板通过 MMC通信通道， 居预先设置的一个或多个监 控信息点向主控板上报受控板的运行状态信息。 为使受控板能够尽早上报运行状态信息， 需要在受控板上电之初就建立 向主控板的上 4艮通道， 因此， 在单板一上电后执行汇编代码的时候就初始化 MMC通信通道， 具体地， 通过汇编代码初始化同 MMC通信的串口， 这样， 就保障了受控板能够完整地上报其运行状态信息。 在受控板， MMC 收到数 据后进行解释， 并通过智能平台管理接口 （Intelligent Platform Management Interface, 简称为 IPMI ) 通道转发到主控板。 主控板与受控板的框架架构参 考图 2, 主控板与受控板通过背板通信， 受控板的运行状态上报模块向主控 板的运行状态记录模块上报运行状态数据。 图 3是根据本发明实施例的单板运行状态的监控方法的优选处理方案的 流程图， 如图 3所示， 该处理包括： 步骤 S302, 主控板启动消息接收监控进程， 随时准备接收来自受控板上 报的运行状态数据， 保障主控板和受控板间的 MMC通信通道的通畅及准确 性， 保证主控板有一定的资源（如存储空间， 任务调度执行等）， 作好监控过 程的准备工作； 步骤 S304, 受控板上电， 初始化开始; 步骤 S306, 判断监控信息点信息是否上报。 单板的运行状态可以分为若 千个阶段， 参考图 4, 单板的运行状态包括： 汇编代码运行阶段、 小系统运 行阶段、 引导 （Boot ) 应用程序执行阶段、 单板控制运行阶段、 上层应用运 行阶段。 根据监控需求， 可以在每个阶段布置一个或多个监控点， 对单板的 各种运行情况进行监控。 一般的上 4艮流程为， 在上电阶段从执行汇编代码初 始化时开始上 4艮启动状态， 随后在 Boot应用程序启动中选择启动点向 MMC 发数据。 依次类推， 在单板控制阶段及上层应用程序阶段选取一些特定的阶 段点上报启动状态。 当然， 对于不需要监控的运行阶段， 也可以不设置监控 信息点； 步骤 S308 , 通过 MMC上 4艮监控信息点的启动轨迹， MMC解释接收到 的消息， 再通过 IPMI通道向主控板上报消息数据； 步骤 S310,驻留在主控板上的消息接收进程接收到数据后对数据进行解 释， 并记录数据到相应数据库中； 步 4聚 S312, 受控板继续运行； 步骤 S314, 判断受控板运行是否完成， 如果没完成则执行步骤 S306, 否则本流程结束。 受控板在上电启动过程中会有一些自检操作， 结果也随同消息一同上报 给主控板。 如果受控板上电启动成功， 则在启动记录中会有完整的运行状态 记录及各种检测结果； 如果启动失败， 则记录中会一直持续到启动失败的前 一刻， 并记录这期间的一些自检结果。 经过上述处理， 用户在主控板上调用 相应命令查看数据库， 能够查到相应受控板整个启动过程轨迹。 轨迹的记录 可以釆用一系列的代码标记， 需要了解具体某项内容时， 只需将记录下的代 号与相应的对照表进行对比即可。 需要注意的是， 由于 CPU串口緩冲区较小， 为避免数据还未发送出去就 被覆盖， 受控板向 MMC发送的数据帧格式应尽量简单， 并且在向串口写数 据时增加一定的延时。 图 5是根据本发明实施例的 MMC通信流程图， 参考 图 5 , 在单板启动后期， MMC通信串口设备初始化后， 串口会被初始化为标 准的 I/O设备进行读写， 此时不能再直接通过写 CPU寄存器来操作串口， 而 需要通过写接口向串口发送数据。 优选地， 受控板向 MMC发送的数据帧应 小于 20字节。 通过上述实施例， 可以非常全面地监控到单板从上电时刻起， 到整个系 统正常工作的运行状态， 形成一个链式监控手段， 可以弥补现有技术对单板 监控的一些空白阶段。 本发明实施例巧妙地利用了 uTCA架构里 MMC的功 能通道， 使得在常规通道失效情况下依旧可以收集受控板的运行状态。 装置实施例 根据本发明的实施例， 还提供了一种单板运行状态的监控装置， 该装置
图 6是根据本发明系统实施例的单板运行状态的监控装置的框图， 图 7 是根据本发明系统实施例的单板运行状态的监控装置的优选结构的框图。 如图 6所示， 根据本发明实施例的单板运行状态的监控装置包括： 建立 模块 10和上报模块 20。 其中， 建立模块 10, 用于受控板上电时建立其与主 控板之间的 MMC通信通道； 上 4艮模块 20 , 连接至建立模块 10 , 用于通过 MMC 通信通道， 根据预先设置的一个或多个监控信息点向主控板上报受控 板的运行状态信息。 如图 7所示， 在图 6所示结构的基础上， 上 4艮模块 20进一步包括： 第 一上报子模块 210 , 用于向 MMC发送受控板的运行状态信息； 第二上报子 模块 220 , 用于 MMC通过 IPMI通道向主控板转发受控板的运行状态信息。 其中，第一上报子模块 210通过写 CPU串口寄存器或者通过调用标准写接口 向 MMC发送运行状态信息。具体地， 在单板启动前期， 第一上报子模块 210 通过写 CPU寄存器来操作串口，在单板启动后期， 第一上报子模块 210通过 调用标准写接口向 MMC的串口发送数据。 由上述叙述可知， 优选地， 第一上报子模块 210 , 位于受控板； 第二上 艮子模块 220 , 位于 MMC。 在第一上 4艮子模块 210 向第二上 4艮子模块 220 发送数据过程中， 数据帧要尽量简单， 优选地小于 20 字节， 且在发送数据 时， 增加一定的数据延时， 以避免运行状态数据还未发送就被删除。 本实施 例单板运行状态的监控装置还可以包括运行状态记录模块， 位于主控板， 与 第二上报模块 220相连， 用于接收第二上报模块 220上报的运行状态数据。 并且， 该装置可以进一步包括： 设置模块（未示出）， 用于预先设置一个 或多个监控信息点， 其中， 监控信息点用以表示受控板的运行阶段的运行状 态， 运行阶段包括以下至少之一： 汇编代码运行阶段、 小系统运行阶段、 引 导应用程序执行阶段、 单板控制运行阶段、 上层应用运行阶段。 在具体实施过程中， 本发明实施例提供的单板运行状态的监控装置的具 体工作流程可以参考图 1至图 5所示的流程。 综上所示， 根据本发明的上述技术方案， 通过 uTCA架构下 MMC的功 能通道， 受控板向主控板上报从上电时刻起， 到系统稳定运行的工作过程的 运行状态， 解决了现有技术中对单板监控的不全面的问题， 能够完整地记录 受控板的运行状态， 使得在常规通道失效情况下依旧可以收集受控板的运行 状态， 对于系统的维护和故障解决具有重要的参考价值。 以上所述仅为本发明的实施例而已， 并不用于限制本发明， 对于本领域 的技术人员来说， 本发明可以有各种更改和变化。 凡在本发明的 ^"神和原则 之内， 所作的任何修改、 等同替换、 改进等， 均应包含在本发明的权利要求 范围之内。
