具体地,在整个通信设备中,每个主电源接入板 21能够为多个单板供电, 当插接新的单板 1后, 该单板 1与 n个主电源接入板 21连接, 此时单板 1中 的 n个开关模块 12是断开状态, 功能模块 11没有上电, 仅仅电源选择模块 13上电, 功耗很小, 电源选择模块 13检测与该单板 1连接的 n个主电源接入 板 21的剩余功率, 首先判断这 n个主电源接入板 21是否能满足该单板 1的 额定功率要求, 若这 n个主电源接入板 21的剩余功率都小于该单板 1的额定 功率, 则 n个开关模块 12保持断开, 该单板 1不会上电; 若这 n个主电源接 入板 21 中部分或全部主电源接入板 21的剩余功率大于或等于该单板 1的额 定功率, 则从中选择一个剩余功率最小的主电源接入板 21作为供电电源接入 板, 控制与该供电电源接入板连接的开关模块 12导通, 使得功能模块 11上 电, 未与该供电电源接入板连接的开关模块 12保持断开, 该单板 1由 n个主 电源接入板 21中使用率最高的一个主电源接入板 21来供电。
本实施例中的单板, 通过开关模块与多个主电源接入板连接, 并选择其 中使用率最高的一个来供电, 即在插入新的单板时, 会从多个主电源接入板 中优先选择一个已经使用的主电源接入板进行供电, 避免了电源接入板的浪 费。 另外, 由于同一个单板可以从多个主电源接入板中进行选择, 因此如果 一路主电源接入板损坏, 该单板可以方便的切换到其他路主电源接入板进行 供电。
可选地, 如图 2所示, 当上述 n个主电源接入板 21相互独立时, 上述每 个开关模块包括正极支路开关 S1和负极支路开关 S2; 正极支路开关 S1的一 端用于连接主电源接入板 21的正极, 正极支路开关 S1的另一端连接于功能 模块 11的正极; 负极支路开关 S2的一端用于连接主电源接入板 21的负极, 负极支路开关 S2的另一端连接于功能模块 11的负极。正极支路开关 S1和负 极支路开关 S2的控制端连接于上述电源选择模块(图 1中未示出 ), 当某个 主电源接入板 21作为供电电源接入板为单板供电时, 电源选择模块控制与这 个供电电源接入板连接的正极支路开关 S1和负极支路开关 S2导通, 未与该 供电电源接入板连接的正极支路开关 S 1和负极支路开关 S2断开。 由于 n个 主电源接入板 21的正极合路接入功能模块 11的正极, n个主电源接入板 21 的负极合路接入功能模块 11 的负极, 而一个主电源接入板 21可能为多个单 板供电, 因此, 为了保证某个主电源接入板 21正极的电流只流向该主电源接 入板 21的负极, 需要在正极支路和负极支路均设置开关。
可选地, 如图 3所示, 当上述 n个主电源接入板 21共用正极时, 上述每 个开关模块可以仅包括负极支路开关 S2,负极支路开关 S2的一端用于连接主 电源接入板 21的负极,负极支路开关 S2的另一端连接于功能模块 11的负极。
可选地, 如图 4所示, 当上述 n个主电源接入板 21共用负极时, 上述每 个开关模块可以仅包括正极支路开关 S1 ,正极支路开关 S1的一端用于连接主 电源接入板 21的正极,正极支路开关 S1的另一端连接于功能模块 11的正极。
具体地, 上述开管模块中的开关器件可以为金属氧化层半导体场效晶体 管( Metal-Oxide- Semiconductor Field-Effect Transistor, MOSFET ),如图 5所示, 上述正极支路开关 S 1或负极支路开关 S2可以包括串联的第一 MOSFET和第 二 MOSFET, 上述第一 MOSFET和第二 MOSFET的寄生二极管方向相反。 由于 MOSFET具有反并的寄生二极管, 即使 MOSFET断开,如果有反向电流 也能够通过寄生二极管反灌。 由于多个主电源接入板 21合路与单板中的功能 模块 11连接, 为了避免供电电源接入板的电流反灌至其他主电源接入板, 因 此由寄生二极管方向相反的两个 MOSFET串联来避免反灌风险。 为其他可控的开关器件。
具体地, 如图 6所示, 上述 n个开关模块 12的第二端还用于分别连接 n 个备用电源接入板 22, n个备用电源计入板 22与上述 n个主电源接入板 21 ——对应, 当某个主电源接入板 21无法使用时, 可以通过相应的备用电源接 入板 22来供电。
可选地,上述 n=2,此时单板和整个通信系统的结构较为简单,容易实现。 单板的具体结构和工作原理与上述实施例相同, 在此不再赘述。
本实施例中的单板, 通过开关模块与多个主电源接入板连接, 并选择其 中使用率最高的一个来供电, 即在插入新的单板时, 会从多个主电源接入板 中优先选择一个已经使用的主电源接入板进行供电, 避免了电源接入板的浪 费。 另外, 由于同一个单板可以从多个主电源接入板中进行选择, 因此如果 一路主电源接入板损坏, 该单板可以方便的切换到其他路主电源接入板进行 供电。
