Description

一种BBU设备
【技术领域】
本发明涉及通信设备技术领域，特别涉及一种BBU设备。
【背景技术】
为了产品能顺利工作，一般BBU（Building Base band Unit，室内基带处理单元）产品都会配置风扇模块来进行辅助散热。风扇模块一般会通过器件与其它部分进行连接，保持信号和电源正常接通。而风扇模块是否是正常的操作拔出，或者没有装配到位，在同类产品中没有进行监控，只是风扇模块在拔出后，系统才会知道风扇模块已不在位，无法识别在不位的原因。风扇模块的工作顺序如下：
BBU风扇模块单元使用时，将模块单元插入系统机框中, 风扇模块单元控制板上的连接器与背板连接器对插后，上电及信号通信，风扇开始运转；当取出风扇模块单元时，连接器分离，断电，风扇停止运行。
在这个过程中，无法识别风扇模块的不在位是被有意识地拔出，还是因为其它原因导致的拔出或者没有插拔到位。为了更好地监控风扇模块的工作状态，需要一个能对于风扇模块的不在位具有识别功能的新模块，从而对风扇模块单元进行管理，使上级系统能即时得到风扇模块的工作状态。
