一种射频拉远模块的温度检测方法和装置
技术领域
本申请涉及通信技术，特别是涉及一种射频拉远模块的温度检测方法和 装置。 背景技术
目前的宽带移动通信中， 大多釆用分布式基站架构， 即室内基带处理单 元 ( Building Base band Unit, BBU )和射频拉远模块 ( Radio Remote Unit, RRU )釆用光纤连接， 但是， RRU通常都安装于较高的天线塔端， 工作环 境比较恶劣， 散热方式釆用的是无源散热， 并且由于 RRU要暴露在室外的 环境， 因此机箱需要密封。
因此， 当空气温度较高时， 尤其是在夏季的中午时段， RRU 的散热能 力受到严峻的挑战， RRU内部的关键部件， 如功放、 电源、 FPGA ( Field - Programmable Gate Array, 现场可编辑逻辑门阵列 )等的性能和寿命会较大 程度的收到温度的大影响。 情况严重时可能会导致 RRU的部件失效， 如功 放烧毁、 电源模块过温保护性断电（烧毁）等， 进而导致所在基站不能工作， 影响网络的覆盖。
由此在 RRU中配置了过温告警， 即设定一个温度门限值， 当 RRU内温 度传感器监测到的箱内温度大于该门限值时， 会向主站上报过温告警消息， 此后没有进一步的处理操作。 同时， 温度监测会每隔一段时间更新一次。
但是， 上述方法中当箱内温度超过门限值后， 虽然上报了过温告警， 但 RRU仍然继续工作且不会进行其他处理操作， RRU机箱内温度可能会继续 上升， 最终可导致功放或电源模块烧毁， 基站失效。 上述的方法仍然没有解 决 RRU温度过高的问题。 发明内容 本申请实施例提供了一种射频拉远模块的温度检测方法和装置， 以解决

为使本申请的上述目的、 特征和优点能够更加明显易懂， 下面结合附图 和具体实施方式对本申请作进一步详细的说明。
本申请实施例提供了一种 RRU的温度检测方法，可以通过配置 RRU的 功率数据， 或关闭 RRU的射频通道来控制 RRU的温度， 防止 RRU由于温 度过高而出现零件烧毁， 基站失效的问题。
实施例一
参照图 1 , 给出了本申请实施例一所述 RRU的温度检测方法流程图。 步骤 101 , 获取 RRU的温度数据。
本实施例中， 可以在 RRU的机箱中配置一个或若干个传感器， 所述传 感器为温度传感器， 因此通过传感器测量 RRU的机箱内的温度， 从而获取 RRU的温度数据。
步骤 102, 检测所述温度数据是否大于温度阈值。
本实施例中配置了一个温度阈值， 所述温度阈值是衡量 RRU的温度是 否过高的标准之一， 所述温度阈值是一个温度范围。
由于温度的变化通常是一个连续的过程， 因此 RRU中温度的变化过程 也是由正常到较高再到过高的。 因此， 本实施例依据温度阈值对温度数据进 行检测时， 可以依据 RRU中温度所处的不同位置， 执行相应的操作， 从而 可以在最初发现 RRU中温度较高时， 就进行相应的处理操作， 保护 RRU稳 定、 正常的工作。
若是， 即所述温度数据大于温度阈值， 则执行步骤 104; 若否， 即所述 温度数据不大于温度阈值， 则执行步骤 105。
可选的， 预置温度门限， 其中， 所述温度门限包括： 第一门限、 第二门 限、 第三门限和第四门限， 所述温度门限中第四门限大于第三门限， 并且第 三门限大于第二门限， 并且第二门限大于第一门限； 釆用温度门限构建温度 阈值对所述温度数据进行分级检测。
步骤 103 , 依据所述温度数据配置所述 RRU的功率数据。
所述温度数据不大于温度阈值包括两种情况： 一种是所述温度数据小于 温度阈值， 另一种是所述温度数据处于温度阈值内。
在 RRU工作时会配置一定的功率数据， 由于相同时间内， 功率越大产 生的热量也就越大， 因此在检测到在温度数据不大于温度阈值时， 可以依据 所述温度数据配置所述 RRU的功率数据， 例如， 将 RRU的功率数据降低几 分贝 （db )等。 从而通过改变功率数据来控制散热量， 从而控制 RRU的温 度。
可选的， 当所述温度数据小于温度阈值时， 依据所述温度数据配置所述 射频拉远模块的功率数据， 包括： 当温度数据小于第一门限时， 所述温度数 据小于温度阈值； 调整所述射频拉远模块的功率数据为初始值。
可选的， 调整所述射频拉远模块的功率数据为初始值之前， 还包括： 若 所述射频拉远模块的射频通道已关闭， 则开启所述射频通道； 若所述射频拉 远模块的射频通道已开启， 则确定所述射频拉远模块的功率数据不等于初始 值。
可选的， 当所述温度数据处于温度阈值内时， 依据所述温度数据配置所 述射频拉远模块的功率数据， 包括：
1 ) 当所述温度数据大于或等于第一门限， 且所述温度数据小于第二门 限时， 所述温度数据处于温度阈值内； 以所述功率数据继续运行所述射频拉 远模块
2 )当温度数据大于或等于第二门限， 且所述温度数据小于第三门限时， 所述温度数据处于温度阈值内； 调整所述射频拉远模块的功率数据为第一功 率值。 3 )当温度数据大于或等于第三门限， 且所述温度数据小于第四门限时， 所述温度数据处于温度阈值内； 调整所述射频拉远模块的功率数据为第二功 率值。
步骤 104, 关闭所述 RRU的射频通道。
可选的， 当所述温度数据大于或等于所述第四门限时， 所述温度数据大 于温度阈值， 则关闭所述射频拉远模块的射频通道。
当所述温度数据大于温度阈值时， 此时 RRU中的温度可能已经过高， 仅改变功率数据可能已经无法控制 RRU的温度了， 因此可以关闭所述 RRU 的射频通道以停止射频通道的工作， 控制 RRU的温度， 防止 RRU由于温度 过高而损坏。
可选的， 所述获取射频拉远模块的温度数据之后， 还包括： 对所述射频 拉远模块的射频通道的开关状态进行检测。
综上所述， 本实施例在获取 RRU的温度数据后， 若温度数据小于或处 于温度阈值内， 则配置 RRU的功率数据， 若温度数据大于温度阈值， 则关 闭 RRU的射频通道。
控制操作， 从而 RRU由于温度过高而损坏（ 实施例二
参照图 2, 给出了本申请实施例二所述 RRU的温度检测方法流程图。 步骤 201 , 预置温度门限。
其中， 所述温度门限包括： 第一门限 TL、 第二门限 TH、 第三门限 Tu 和第四门限 Toff, 并且， TL<TH<Tu<Toff。 假设 RRU的温度数据是 T。 具 体包括：
1 ) 第一门限 TL。
TL是恢复正常功率的温度门限， 也可以作为恢复开启射频通道的门限。 即在达到丁<11^时， 可以将 RRU的功率恢复正常， 即恢复为初始值。
其中， 若 RRU的射频通道处于关闭状态， 则开启射频通道并将 RRU的 功率恢复为初始值。若 RRU的射频通道处于开启状态，则此时还要将该 RRU 的功率数据与初始值进行比较， 在确定该 RRU的功率数据是初始值时， 可 以继续以初始值运行该 RRU, 而不执行其他操作； 此时若确定该 RRU的功 率数据不是初始值， 则将 RRU的功率恢复为初始值。
2 ) 第二门限 TH。
TH是下调 RRU功率的温度门限之一， 用于对 RRU的温度进行控制。 即在 T>TH时， 可以下调 RRU的功率。
3 ) 第三门限 Tu。
Tu是另一个下调 RRU功率的温度门限， 用于进一步对 RRU的温度进 行控制。 即在 T>Tu时， 则进一步调整该 RRU的功率。
4 ) 第四门限 Toff。
Toff是关闭射频通道的门限， 即在检测 T>Toff时， 可以关闭 RRU的射 频通道，从而对 RRU的温度进行控制，防止由于温度过高造成 RRU的损坏。
通过上述温度门限， 可以对温度进行分级检测。
其中， 在配置温度门限时， 可以依据设备在研发阶段高低温测试中得到 的统计数据， 以保护设备在极端条件下不被损坏为原则。 由于不同设备的容 限有区别， 所以温度门限值需要根据各款设备的实测数据作为设置依据， 以 保证设备能够工作在安全温度范围之内。
例如， 通过实验数据分析得知， 温度为 90°C以上会导致某 RRU中关键 部件受损或烧毁， 而在温度为 70 °C以内时设备中各器件均无损坏风险， 因 此可以将上述各温度门限设置为：
TL = 70 °C, TH = 75 °C, Tu = 85 °C, Toff= 90 oC。
步骤 202, 釆用温度门限构建温度阈值。
因而可以釆用温度门限构建温度阈值， 从而实现对 RRU的温度数据进 行分级检测， 依据温度数据所处的不同温度范围， 执行相应的操作， 更好地 控制 RRU的温度。
步骤 203 , 获取 RRU的温度数据。
现有技术在获取温度数据时， 有时可能会获取的不准确的异常数值， 但 由于没有异常数值的检测方法， 因而可能会获取异常的温度数据， 从而导致 RRU中温度获取不准确。
本实施例针对上述问题， 在 RRU中配置了若干传感器， 并配置了设定 值， 用于检测传感器传输的温度是否出现异常。
可选的， 所述获取 RRU的温度数据， 包括：
读取所述 RRU中各传感器传输的温度， 若任意两个传感器传输的温度 的绝对差值大于设定值， 则重新读取各传感器传输的温度； 否则， 将各传感 器传输的温度作为所述 RRU的温度数据。
本实施例在 RRU的各功放（功率放大器）处， 和 RRU中出功放外的其 他区域分别配置了传感器， 因此， 根据传感器所处的不同位置， 对传输的温 度的衡量方法也略有不同， 具体包括如下步骤：
参照图 3 , 给出了本申请实施例二所述 RRU的温度获取方法流程图。 可选的， 所述读取所述射频拉远模块中各传感器传输的温度， 若任意两 个传感器传输的温度的绝对差值大于设定值， 则重新读取各传感器传输的温 度； 否则， 将各传感器传输的温度构成所述射频拉远模块的温度数据， 包括 以下步骤：
