本发明涉及通信领域， 尤其涉及一种告警方法和装置。
背景技术
在微波传输系统中， 需要实时检测该系统中的室外单元 (Outdoor Unit, ODU)的 运行状态。 当室外单元出现故障隐患时， 做到及时发现并排除该故障隐患是保 证微波传输系统的传输质量和提高客户满意度的必要工作。
现有技术中， 只有在微波传输系统的室外单元出现损坏并发出告警的情况 下才对微波传输系统的室外单元进行故障排查和维修。 但是， 由于微波传输系 统的室外单元通常安装于铁塔、 楼顶或偏远的山区， 对微波传输系统中出现损 坏的室外单元排除故障时， 则需要占用较长的时间， 有的需要几天、 有的甚至 需要一两个月的时间， 这样对微波传输系统的业务和客户满意度造成了严重影 响。
因此， 微波传输系统的室外单元若能做到自身的告警， 即微波传输系统的 室外单元已经出现故障但还没有达到影响微波传输系统的业务的程度时， 就及 时发出预警信息就显得十分重要。
目前， 通过定期检测微波传输系统中的室外单元内部的电路状态可以来达 到预警的目的。 但是， 该室外单元的内部电路状态的检测点很多， 通常要设置 很多检测点， 这样不但会增加成本， 而且往往会误报达不到预警的目的。 发明内容

具体实施方式
下面通过附图和实施例， 对本发明的技术方案做进一步的详细描述。
本发明公开了一种告警方法和装置， 该方法和装置获取主用单元的第一接 收功率和备用单元的第二接收功率， 通过对第一接收功率和第二接收功率的功 率对比来决定备用单元需要重点关注并对备用单元告警还是主用单元需要重点 关注并对主用单元告警； 或者获取本端单元的第一接收功率和第一发射功率以 及对端单元的第二接收功率和第二发射功率， 通过对第一接收功率、 第一发射 功率、 第二接收功率和第二发射功率的功率对比来决定对端单元需要重点关注 并对对端单元告警还是本端单元需要重点关注并对本端单元告警。
图 1为本发明实施例提供的一网元釆用 1+1保护配置方式的示意图。 如图 所示， 本发明实施例的网元结构具体包括： 主用单元 11、 备用单元 12、 合路器 13和天线 14。 该网元应用于微波室外单元， 并釆用了 1+1保护配置方式。 1+1 保护配置方式是微波链路的一种保护配置方式， 具体包括釆用热备份 ( Hot StandBy, HSB )、 空间分集（ Space Diver s i ty, SD )、 频率分集（ Frequency Divers i ty, FD ) 的配置方式。 其中， HSB方式指的是一种保障设备安全运行的 方法， 两个设备都是启动的， 一个设备在工作， 另一个设备处于备用状态。 一 旦工作的设备发生故障， 备用的设备可以马上接管工作。 SD方式指的是釆用两 个或两个以上具有一定空间间隔的天线同时发送或接收同一信息， 然后进行选 择， 以减轻衰落影响。 目前 SD方式一般只釆用接收分集的方式。 FD方式指的是 一种分频方案， 釆用两个或两个以上具有一定频率间隔的微波频率同时发送和 接收同一信息， 然后进行选择， 以减轻衰落影响。
下面以 HSB方式为例， 具体说明该设置为 1+1保护配置方式的网元的各个 组成部分的功能。
主用单元 11和备用单元 12 负责射频处理， 实现中频、 射频信号转换。 通 常情况下， 主用单元 11开启射频发射， 而备用单元 12则保持静默。 当主用设 备 11出现故障时， 则从备用设备 12选收业务， 同时关闭主用单元 11的射频发 射， 同时开启备用单元 12的射频开关以保证发送到对端设备接收的业务能够恢 复正常。 主用单元 11和备用单元 12均接收来自对端设备的信号。 其中， 对端 设备也釆用 1+1保护配置方式。
合路器 13用来汇合来自两个设备单元（主用单元 11和备用单元 12 ) 的信 号并把射频信号传送给天线， 或者把来自天线的信号分流到两个设备单元即主 用单元 11和备用单元 12。
天线 14 的作用把主用单元 11 或备用单元 12发出的射频能量定向辐射出 去， 或者把接收下来的射频能量传输给主用单元 11和备用单元 12。
因此， 微波室外单元的网元釆用 1+1 保护配置方式， 可以提高整个通信系 统的可靠性， 而且釆用备用单元的方法， 可以对主用单元和波道进行保护。 因 为网元中除了传送信息的主用单元或工作波道外， 还附有作为备份手段的备用 单元和备用波道。 一旦主用单元发生故障， 或是误码率恶化到一定门限， 可以 自动切换到备用单元或备用波道上去或者强制切换到备用单元或备用波道上。
图 2 为本发明实施例提供的一告警方法的流程图。 如图所示， 本发明实施 例具体包括以下步骤：
步骤 201 , 获取主用单元的第一接收功率 RSL1和备用单元的第二接收功率 RSL2。
具体的， 主用单元利用室外单元实现； 同时， 备用单元也利用室外单元实 现 因此获取的第一接收功率 RSL1为主用室外单元的第一接收功率 RSL1; 同理， 获取的备用单元的第二接收功率 RSL2为备用室外单元的第二接收功率 RSL2。
另外， 步骤 201还可以先查询网元是否设置为 1+1保护配置方式。 其中， 1+1保护配置方式是微波链路的一种保护配置方式， 该方式不仅具有主用设备即 主用单元， 还具有备份设备即备用单元。 只有当该网元设置为 1+1 保护配置方 式， 表明利用软件巡检工具能够实现对于该网元的主用单元和备用单元的运行 状态自动判断， 并确定是否需要发出告警信息时， 再获取主用单元的第一接收 功率 RSL1和备用单元的第二接收功率 RSL2。
步骤 202 , 计算第一接收功率 RSL1与第二接收功率的功率差值 dl。 其中， 功率差值 dl的计算过程如公式（ 1 ) 所示。
dl=RSLl-RSL2 公式（ 1 ) 步骤 203 , 判断功率差值 dl是否为正值。 当功率差值 ^为正值时， 则进行 步骤 104; 当功率差值 dl不为正值时， 则进行步骤 206。
步骤 204 , 判断功率差值 dl是否不小于第一阔值 Tl。 当第一差值 dl不小 于第一阔值 T1时， 则进行步骤 205; 当第一差值 dl小于第一阔值 T1时， 则进 行步骤 209。
步骤 205 , 当功率差值 dl不小于第一阔值 T1时， 如公式（2 )所示。 则对 备用单元告警。
d\ > T\ 公式（2 ) 其中， 该第一阔值 T1是根据实际情况设置的， 比如设置为 15db。
具体地， 当功率差值 dl不小于第一阔值 T1 时， 说明此时备用单元的功率 衰减很厉害， 否则之前就报警了， 这时备用单元需要重点关注， 有可能产生故 障或者存在隐患， 还有可能此时备用单元已经出现故障但还没有影响微波传输 业务， 所以此时告警， 可以提前对其进行检查和处理， 从而将隐患消除在萌芽 状态或者出现重大事故之前， 这样对保障业务运行质量和客户满意度有很大的 帮助。
步骤 206, 判断功率差值 dl是否为负值。 当功率差值 dl为负值时， 则进行 步骤 207; 当功率差值 dl为 0时， 则进行步骤 209。
步骤 207 , 判断功率差值 dl是否不小于第二阔值 T2。 当功率差值 dl不小 于第一阔值 T2时， 则进行步骤 208; 当功率差值 dl小于第一阔值 T1时， 则进 行步骤 209。
步骤 208 , 当功率差值 dl不小于第二阔值 T2时， 如公式（3 )所示。 则对 主用单元告警。
d ≥T2 公式（3 ) 其中， 该第一阔值 T2是根据实际情况设置的， 比如设置为 -9db。 另外， 该 第一阔值 T2也可以与第一阔值 T1可以相同， 也可以不同。
具体地， 当功率差值 dl不小于第一阔值 T2时， 说明此时主用单元的功率 衰减很厉害， 否则之前就报警了， 这时主用单元需要重点关注， 有可能产生故 障或者存在隐患， 还有可能此时主用单元已经出现故障但还没有影响微波传输 业务， 所以此时告警， 可以提前对其进行检查和处理， 从而将隐患消除在萌芽 状态或者出现重大事故之前， 这样对保障业务运行质量和客户满意度有很大的 帮助。
步骤 209 , 巡检结束， 表明网元运行状态正常， 不发出告警信号。
另外， 本发明实施例提供的告警方法是将查询网元的保护配置方式， 以及 为了决定是否发出预警信号而进行功率比对的方法加入到软件巡检工具中， 利 用该软件巡检工具对微波传输系统进行巡检的。
因此， 本发明实施例提供的告警方法， 该方法通过获取主用单元的第一接 收功率和备用单元的第二接收功率， 通过对第一接收功率和第二接收功率的功 率对比来决定对备用单元告警还是对主用单元告警， 实现了对主用单元和备用 单元的潜在故障进行预警的目的， 即主用单元和备用单元在还没有达到影响业 务的程度是及时预警， 而且该方法易于实现， 还不增加过多的成本。
图 3为本发明实施例提供的另一网元釆用 1+0保护配置方式的示意图。 如 图所示， 该网元设置了 1+0保护配置， 其具体包括： 本端单元 31、 对端单元 32、 本端天线 33和对端天线 34。 该网元应用于微波链路的两端， 并釆用了 1+0保护 配置方式。 其中， 1+0保护配置方式是微波链路的另一种保护配置方式。 下面具 体说明该设置为 1+1保护配置方式的网元的各个组成部分的功能。
本端单元 31和对端单元 32 负责射频处理， 实现中频、 射频信号转换。 本 端单元 31和对端单元 32均开启射频发射， 均接收来自对端设备的信号。
本端天线 33的作用是把本端单元 31发出的射频能量定向辐射出去， 把接 收下来的射频能量传输给本端单元 31。
对端天线 34的作用是把对端单元 32发出的射频能量定向辐射出去， 把接 收下来的射频能量传输给对端单元 32。
图 4 为本发明实施例提供的另一告警方法的流程图。 如图所示， 本发明实 施例具体包括以下步骤：
步骤 401 , 获取本端单元的第一接收功率 RSL1和第一发射功率 TX1以及对 端单元的第二接收功率 RSL2和第二发射功率 TX2。
具体的， 本端单元利用室外单元实现， 同时， 对端单元也室外单元实现， 因此获取的第一接收功率 RSL1和第一发射功率 TX1为本端室外单元的第一接收 功率 RSL1和第一发射功率 TX1; 同理， 获取的对端单元的第二接收功率 RSL2和 第二发射功率 ΤΧ2为对端室外单元的第二接收功率 RSL2和第二发射功率 ΤΧ2。
另外， 步骤 401还可以先查询网元是否设置为 1+0保护配置方式。 其中， 1+0保护配置方式是微波链路的另一种保护配置方式， 在该方式中微波链路的本 地端只有主用设备即主用单元， 而没有备份设备即备用单元； 同时对端也只有 主用设备即主用单元， 而没有备份设备即备用单元。 只有当该网元设置为 1+0 保护配置方式， 表明利用软件巡检工具能够实现对于该网元链路两端的本端单 元和对端单元的运行状态自动判断， 并确定是否需要发出告警信息时， 再获取 本端单元的第一接收功率 RSL1和第一发射功率 TX1以及对端单元的第二接收功 率 RSL2和第二发射功率 ΤΧ2。
步骤 40 计算第一发射功率 TX1与第二接收功率 RSL2的第一功率差值 dl, 其中第一功率差值 ^的计算过程如公式（4 )所示。 dl=TXl-RSL2 公式（ 4 ) 步骤 40¾计算第二发射功率 TX2与第一接收功率 RSL1的第二功率差值 d 其中第二功率差值 d2的计算过程如公式（ 5 )所示。
d2=TX2-RSLl 公式（ 5 ) 步骤 404, 计算第一功率差值 dl与第二功率差值 d2的之间的功率差值的绝 对值 6 )所示。
Figure imgf000009_0001
公式（ 6 ) 步骤 405, 判断第一功率差值 dl与第二功率差值 d2的之间的功率差值的绝 对值 d3是否不小于预设阔值 T。 当第一功率差值 dl与第二功率差值 ^的之间 的功率差值的绝对值 d3不小于预设的阔值 时， 则进行步骤 408; 当所第一功 率差值 dl与第二功率差值 d2的之间的功率差值的绝对值 d3小于预设的阔值 时， 则进行步骤 407。 其中， 预设阔值 是根据实际情况提前设置的， 比如设置 为 10db。
步骤 406 , 巡检结束， 表明网元运行状态正常， 不发出告警信号。
步骤 407, 判断第一功率差值 dl是否大于第二功率差值 d2。 当第一功率差 值 dl大于第二功率差值 d2时， 则进行步骤 409; 当第一功率差值 dl不大于功 率第二差值 d2时， 则进行步骤 410。
步骤 408, 当确认第一功率差值 dl大于第二功率差值 d2时， 则对对端单元 告警。
具体地， 当确认第一功率差值 dl 大于第二功率差值 d2时， 说明此时对端 单元的功率衰减很厉害， 否则之前就报警了， 这时对端单元需要重点关注， 有 可能产生故障或者存在隐患， 还有可能此时对端单元已经出现故障但还没有影 响微波传输业务， 所以此时告警， 可以提前对其进行检查对故障网元进行检查 和处理， 从而将隐患消除在萌芽状态或者出现重大事故之前， 这样对保障业务 运行质量和客户满意度有很大的帮助。
步骤 409, 当确认第一功率差值 dl不大于第二功率差值 d2时， 则对本端单 元告警。
具体地， 当确认第一功率差值 dl不大于第二功率差值 d2时， 说明此时本 端单元的功率衰减很厉害， 否则之前就报警了， 这时本端单元需要重点关注， 有可能产生故障或者存在隐患， 还有可能此时本端单元已经出现故障但还没有 影响微波传输业务， 所以此时告警， 可以提前对其进行检查对故障网元进行检 查和处理， 从而将隐患消除在萌芽状态或者出现重大事故之前， 这样对保障业 务运行质量和客户满意度有很大的帮助。
另外， 本发明实施例提供的告警方法是将查询网元的保护配置方式， 以及 为了决定是否发出预警信号而进行功率比对的方法加入到软件巡检工具中， 利 用该软件巡检工具对微波传输系统进行巡检的。
因此， 本发明实施例提供的告警方法， 通过获取本端单元的第一接收功率 和第一发射功率以及对端单元的第二接收功率和第二发射功率， 通过对第一接 收功率、 第一发射功率、 第二接收功率和第二发射功率的功率对比来决定对对 端室外单元告警还是对本端单元告警， 实现了对对端单元和本端单元的潜在故 障进行预警的目的， 即对端单元和本端单元在还没有达到影响业务的程度是及 时预警， 而且该方法易于实现， 还不增加过多的成本。

具体地， 当功率差值 dl不小于第一阔值 T1 时， 说明此时备用单元的功率 衰减很厉害， 否则之前就报警了， 这时备用单元需要重点关注， 有可能产生故 障或者存在隐患， 还有可能此时备用单元已经出现故障但还没有影响微波传输 业务， 所以此时告警， 可以提前对其进行检查和处理， 从而将隐患消除在萌芽 状态或者出现重大事故之前， 这样对保障业务运行质量和客户满意度有很大的 帮助。
当功率差值 dl 不小于第一阔值 T2时， 说明此时主用单元的功率衰减很厉 害， 否则之前就报警了， 这时主用单元需要重点关注， 有可能产生故障或者存 在隐患， 还有可能此时主用单元已经出现故障但还没有影响微波传输业务， 所 以此时告警， 可以提前对其进行检查和处理， 从而将隐患消除在萌芽状态或者 出现重大事故之前， 这样对保障业务运行质量和客户满意度有很大的帮助。
