The board is used for simple smooth filtering of the input power, so the function is simple and the volume is small. In the second case, the environment power supply cannot meet the SDH equipment. The input voltage requirement cannot directly supply power to the device. Therefore, the SDH device needs to be powered by the power conversion board. The device needs to use the power conversion board to convert the ambient power into a voltage that the device can support. The board is used to reverse the DC power through the oscillating circuit. It becomes an alternating current, and after being boosted by a transformer, it is rectified to obtain high-voltage direct current, so the function is complicated and the volume is large.

If the power interface board or the power conversion board occupies more slots, the number of slots occupied by the service board is reduced. For the second case, each of the larger power conversion boards occupies one slot, which cannot meet the space requirements of the compact device. This reduces the slot of the service board and affects the service access capacity. Summary of the invention

以下结合附图， 对本发明的具体实施方式进行详细描述。  The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.
本发明提供的 SDH设备的槽位布局方法将电源功能板槽位和业务板槽 位兼容布局在背板上的兼容槽位。 其中， 电源功能板包括电源转换板、 电 源接口板等用于电源控制的器件， 该兼容槽位的槽位结构、 总线连接方式 都与业务板槽位类似， 不仅支持电源功能板插入， 还支持业务板插入。 当 该兼容槽位插电源功能板时， 电源功能板与兼容槽位提供的电源功能板总 线连接； 当该兼容槽位插业务板时， 业务板与兼容槽位提供的业务板总线 连接。 例如当 SDH设备在某种应用场景中， 环境电源不能满足 SDH设备 的输入电压要求， 无法直接给设备供电时， 需要将电源转换板插在背板的 对应槽位上给 SDH设备供电， 由于电源转换板体积较大， 每个电源转换板 占用子架上的一个整体的兼容槽位； 同时， 该兼容槽位还支撑业务板的插 入使用。 较佳地， 背板上有两个兼容槽位。 The slot layout method of the SDH device provided by the present invention is compatible with the slot of the power function board and the slot of the service board in a compatible slot on the backplane. The power function board includes a power conversion board, a power interface board, and the like for power control. The slot structure and the bus connection mode of the compatible slot are similar to those of the service board slot, and not only support the power function board insertion, but also support. Business board is inserted. When the compatible slot is inserted into the power function board, the power board is connected to the power board bus provided by the compatible slot. When the compatible slot is inserted into the service board, the service board is connected to the service board bus provided by the compatible slot. For example, when an SDH device is in an application scenario, the environment power supply cannot satisfy the SDH device. The input voltage is required. When the power supply cannot be directly supplied to the device, the power conversion board needs to be inserted into the corresponding slot on the backplane to supply power to the SDH device. Because the power conversion board is large, each power conversion board occupies one of the subracks. The overall compatible slot; at the same time, the compatible slot also supports the insertion and use of the service board. Preferably, there are two compatible slots on the backplane.
如图 1所示的实施方式中， 子架具有 8个整体槽位。 其中， 主用电源 接口板槽位 1和备用电源接口板槽位 2釆用 1+1主备保护的模式， 布局在 背板上的一个共用槽位，每个电源接口板槽位占用 1/2的整体槽位。 由于电 源接口板仅用于接入环境电源， 且处理过程较简单， 体积较小， 因此这种 布局方式能够有效节省设备空间。 例如当环境电源提供 48V的电压时， 可 直接将电源接口板插在电源接口板槽位 1 , 为插在业务板槽位 5、 业务板槽 位 6、 业务板槽位 7、 业务板槽位 8、 业务板槽位 9等槽位的业务板供电。  In the embodiment shown in Figure 1, the subrack has eight integral slots. The main power supply board slot 1 and the standby power interface board slot 2 are in the 1+1 active/standby mode. The layout is on a common slot on the backplane. Each power interface board slot occupies 1/1. 2 overall slot. Since the power interface board is only used to access the environment power supply, and the processing process is simple and small, this layout method can effectively save equipment space. For example, when the ambient power supply provides a voltage of 48 V, you can directly insert the power interface board into the slot of the power interface board. The slot is in slot 5 of the service board, slot 6 of the service board, slot 7 of the service board, and slot of the service board. 8. The service board of the service board slot is powered by 9 slots.
电源转换板槽位（即电源功能板槽位） 同样釆用 1+1保护模式， 包括 主用电源转换板槽位和备用电源转换板槽位， 二者各占用背板上的一个兼 容槽位， 即图 1中的兼容槽位 3和兼容槽位 4, 这两个兼容槽位同时支持业 务板的插入使用。 例如当环境电源提供 24V的电压， 而设备需要 48V电压 时， 可直接将电源转换板插在兼容槽位 3 ,从而为插在背板上的各业务板供 电。  The power conversion board slot (that is, the power function board slot) also uses the 1+1 protection mode, including the main power conversion board slot and the standby power conversion board slot, which each occupy a compatible slot on the backplane. That is, compatible slot 3 and compatible slot 4 in Figure 1, these two compatible slots support the insertion of the service board at the same time. For example, when the ambient power supply provides 24V and the device requires 48V, the power conversion board can be directly inserted into the compatible slot 3 to supply power to each service board inserted in the backplane.
本实施方式的槽位布局方式具有很强的适用性， 不仅能够用于普通的 电源环境， 而且在需要转换电压的特殊电源环境下， 不需要修改背板专门 设计电源转换板槽位， 就能满足供电需求， 同时避免电源功能板占用过多 槽位而对设备的业务容量造成影响。  The slot layout mode of the embodiment has strong applicability, and can be used not only in an ordinary power supply environment, but also in a special power environment where a voltage needs to be converted, without modifying the backplane to specifically design a power conversion board slot. The power supply needs are met, and the power function board is prevented from occupying too many slots, which affects the service capacity of the device.
在本实施方式 SDH设备的槽位布局方法中， 还对兼容槽位提供的各种 总线进行合理布局。  In the slot layout method of the SDH device in this embodiment, various buses provided in compatible slots are also reasonably arranged.
电源功能板总线包括多种， 例如对于电源转换板， 电源功能板总线包 括电源接口和电源转换板控制总线， 电源接口即电源转换板的接口插座， 通常需要保证其安装的牢固性； 电源转换板控制总线用于网元控制板对电 源转换板进行监控， 网元控制板还可通过电源接口板控制总线对电源接口 板进行监控， 这些控制总线包括在位线、 输入电压告警线等。 业务板总线 包括开销总线、 控制总线、 数据总线、 时钟总线等。 为了便于信息的顺利 传输和网元控制板的有效监控， 同一兼容槽位中的电源功能板总线与业务 板总线应当分开布局。 为了避免电源接口与电源转换板控制总线之间的相 互影响， 同一兼容槽位提供的电源转换板控制总线与电源接口也分开布局。 The power function board bus includes a plurality of types, for example, a power conversion board, the power function board bus includes a power interface and a power conversion board control bus, and the power interface is an interface socket of the power conversion board.

When the power conversion board control bus and the common slot provide the main power interface board control bus and the standby power interface board control bus, the main power conversion board control bus is shared with the main power interface board control bus, and the standby power conversion board controls the bus and The standby power interface board controls bus sharing. For example, the bit line 1 of the main power supply interface board and the compatible slot 3 are shared by the bit line and the input voltage alarm line. The slot of the standby power interface board 2 and the compatible slot 4 are shared by the bit line and the input voltage alarm line.
