本发明实施例的主要思路是: 在设备的电源单板上只进行电压的欠压 检测, 当检测到欠压告警后, 将欠压告警信号上报给主控单板, 由主控单 板来检测设备业务单板的运行状态, 如果发现业务单板运行异常, 则在欠 压告警消失之后, 自动下发复位命令, 使得异常的业务单板重新初始化, 恢复正常状态。
如图 1 所示, 本发明一实施例提出一种低电压升高后设备状态恢复的 方法, 包括:
步驟 S101 , 主控单板接收到电源单板上报的欠压告警信号时, 检测业 务单板的运行状态;
由于通信设备对电压的敏感, 都配备有自身的电源单板, 实现浪涌保 护、 过载保护等, 可以在电源单板上实现欠压和过压保护。 本实施例方法 采用一种单板级的保护方式, 对于某些实际上不会影响设备的业务单板不 需与其他业务单板一起断电。
具体地, 在设备的电源单板上进行电压的欠压检测, 当电源单板上电 后, 电源单板对输入电压进行实时检测, 并将检测结果通过内部信号线传 输给主控单板。 当电源单板检测到电压低于预先设定的门限电压时, 则输 出欠压告警信号至主控单板。 主控单板收到电源单板上报的欠压告警信号 后, 检测业务单板的运行状态。
在业务单板侧, 当业务单板上电后, 在运行过程中, 业务单板实时检 测自身的运行状态, 当检测到运行状态异常时, 比如业务单板检测自身业 务芯片存在有配置丟失、 芯片状态异常等, 则向主控单板上报状态异常信 号, 作为告警指示。
若主控单板接收到业务单板上报的状态异常信号, 则表明检测到业务 单板运行异常; 否则, 检测到业务单板运行正常。 步驟 S102, 当检测到业务单板运行异常, 且接收到电源单板上报的欠 压告警消失信号时, 向业务单板发送复位指令, 使业务单板恢复正常状态。
当电源单板检测到电压从低于预先设定的门限电压恢复至正常电压 时, 则输出欠压告警消失信号至主控单板。 主控单板正常运行过程中, 接 收到电源单板上报的欠压告警消失信号时, 向异常的业务单板发送复位指 令, 异常的业务单板收到复位指令后, 重新进行初始化操作, 恢复正常状 态。
本发明实施例根据通信设备具备外部使能复位的特点, 以电源单板的 低电压检测结果, 在机房电源异常时, 电源单板上报欠压告警信号, 主控 单板检测业务单板的运行状态; 当业务单板运行异常, 在电源单板上报欠 压告警消失信号时, 主控单板向业务单板发送复位指令, 使状态异常的业 务单板恢复正常状态, 从而最大限度的保护了用户的业务正常运行, 并减 少了用户的投资成本。
如图 1 所示, 本发明另一实施例提出一种低电压升高后设备状态恢复 的方法, 包括:
步驟 S201 , 主控单板接收到电源单板上报的欠压告警信号时, 在非易 失存储器中写入欠压告警标识, 并检测业务单板的运行状态;
步驟 S202, 当检测到业务单板运行异常, 且接收到电源单板上报的欠 压告警消失信号时, 向业务单板发送复位指令, 使业务单板恢复正常状态; 步驟 S203 , 根据电源单板上报的欠压告警消失信号清除非易失寄存器 中的欠压告警标识。
本实施例与上述实施例的区别在于, 主控单板接收到电源单板上报的 欠压告警信号时, 在非易失存储器中写入欠压告警标识, 同时, 在主控单 板上电运行时, 主控单板要判断非易失存储器中是否存在欠压告警标识, 若存在, 则检测业务单板的运行状态, 当检测到业务单板运行异常, 且接 收到电源单板上报的欠压告警消失信号时, 向业务单板发送复位指令, 使 业务单板恢复正常状态。 同时, 根据电源单板上报的欠压告警消失信号清 除非易失寄存器中的欠压告警标识。
此外, 在主控单板重新上电运行时, 进行了之前一系列的判断和复位 处理之后, 并且判断当前电源单板没有欠压告警信号上报, 若非易失存储 器中存在欠压告警标识, 则对其进行清除。
本实施例根据通信设备具备外部使能复位的特点, 以电源单板的低电 压检测结果, 在机房电源异常时, 电源单板上报欠压告警信号, 主控单板 检测业务单板的运行状态; 当业务单板运行异常, 在电源单板上报欠压告 警消失信号时, 主控单板向业务单板发送复位指令, 使状态异常的业务单 板恢复正常状态; 同时, 通过非易失寄存器存储记录欠压告警标识, 使得 主控单板可以实时监控电源单板的检测结果, 同时更好的控制业务单板的 运行状态。 从而最大限度的保护了设备承载的业务正常运行, 即提高了设 备承载业务性能, 并减少了用户的投资成本。
如图 3 所示, 本发明一实施例提出一种低电压升高后设备状态恢复的 主控单板, 包括: 接收检测模块 301及控制模块 302, 其中:
接收检测模块 301 , 用于接收到电源单板上报的欠压告警信号时,检测 业务单板的运行状态;
控制模块 302, 用于当检测到业务单板运行异常,且接收到电源单板上 报的欠压告警消失信号时, 向业务单板发送复位指令, 使业务单板恢复正 常状态。
由于通信设备对电压的敏感, 都配备有自身的电源单板, 实现浪涌保 护、 过载保护等, 可以在电源单板上实现欠压和过压保护。 本实施例采用 一种单板级的保护方式, 对于某些实际上不会影响设备的业务单板不需与 其他业务单板一起断电。 具体地, 在设备的电源单板上进行电压的欠压检测, 当电源单板上电 后, 电源单板对输入电压进行实时检测, 并将检测结果通过内部信号线传 输给主控单板。 当电源单板检测到电压低于预先设定的门限电压时, 则输 出欠压告警信号至主控单板。 主控单板的接收检测模块 301 收到电源单板 上报的欠压告警信号后, 检测业务单板的运行状态。
在业务单板侧, 当业务单板上电后, 在运行过程中, 业务单板实时检 测自身的运行状态, 当检测到运行状态异常时, 比如业务单板检测自身业 务芯片存在有配置丟失、 芯片状态异常等, 则向主控单板上报状态异常信 号, 作为告警指示。
若主控单板接收到业务单板上报的状态异常信号, 则表明检测到业务 单板运行异常; 否则, 检测到业务单板运行正常。
当电源单板检测到电压从低于预先设定的门限电压恢复至正常电压 时, 则输出欠压告警消失信号至主控单板。 在主控单板正常运行过程中, 控制模块 302接收到电源单板上报的欠压告警消失信号时, 向异常的业务 单板发送复位指令, 异常的业务单板收到复位指令后, 重新进行初始化操 作, 恢复正常状态。
如图 4所示, 本发明另一实施例提出一种低电压升高后设备状态恢复 的主控单板, 包括: 接收检测模块 401、 控制模块 402以及清除模块 403 , 其中:
接收检测模块 401 , 用于接收到电源单板上报的欠压告警信号时, 在非 易失存储器中写入欠压告警标识, 并检测业务单板的运行状态;
控制模块 402, 用于当检测到业务单板运行异常,且接收到电源单板上 报的欠压告警消失信号时, 向业务单板发送复位指令, 使业务单板恢复正 常状态。
清除模块 403 ,用于根据电源单板上报的欠压告警消失信号清除非易失 寄存器中的欠压告警标识。
进一步的, 接收检测模块 401 还用于当主控单板上电运行时, 判断非 易失存储器中是否存在欠压告警标识, 若存在, 则检测业务单板的运行状 态。
本实施例与上述实施例的区别在于, 主控单板的接收检测模块 401接 收到电源单板上报的欠压告警信号时, 在非易失存储器中写入欠压告警标 识, 同时, 在主控单板上电运行时, 接收检测模块 401要判断非易失存储 器中是否存在欠压告警标识, 若存在, 则检测业务单板的运行状态, 当检 测到业务单板运行异常, 且接收到电源单板上报的欠压告警消失信号时, 控制模块 402向业务单板发送复位指令, 使业务单板恢复正常状态。
同时, 由清除模块 403根据电源单板上报的欠压告警消失信号清除非 易失寄存器中的欠压告警标识。
如图 5 所示, 本发明还提出一种低电压升高后设备状态恢复的系统, 包括: 电源单板 501、 业务单板 502以及主控单板 503 , 其中:
电源单板 501 , 用于向业务单板 502输入电源, 并当检测到电压低于预 设的门限电压时, 向主控单板 503 上报欠压告警信号; 当检测到电压恢复 正常时, 向主控单板 503上报欠压告警消失信号;
业务单板 502, 用于接收电源单板 501输入的电源, 并在检测到自身的 运行状态异常时, 向主控单板 503上报状态异常信号; 当收到主控单板 503 发送的复位指令时, 进行重新初始化操作, 恢复正常状态;
主控单板 503 , 用于接收到电源单板上报的欠压告警信号时,检测业务 单板 502的运行状态; 当检测到业务单板 502运行异常, 且接收到电源单 板 501上报的欠压告警消失信号时, 向业务单板 502发送复位指令, 使业 务单板 502恢复正常状态。
进一步的, 主控单板 503还用于当接收到电源单板 501上报的欠压告 警信号时, 在非易失存储器中写入欠压告警标识; 并根据电源单板 501 上 报的欠压告警信号清除非易失寄存器中的欠压告警标识。
更进一步的, 主控单板 503还用于上电运行时, 判断非易失存储器中 是否存在欠压告警标识, 若存在, 则检测业务单板 502的运行状态。
