Embodiment 2

[0039] Embodiment 2 of the present invention provides a transmission method for managing power supply, the method including:

[0040] converting the external power supply into a management power supply;

[0041] The management power supply is sequentially passed through the bus, and the branch line divided by the bus and connected to the backplane slot is input to the backplane slot.

[0042] Wherein, the branch line includes a primary branch line, and the primary branch line is connected to the backplane slot. Specifically, the management power is sequentially input to the backplane slot through the bus and the primary branch line.

[0043] Wherein, the branch line may include a primary branch line and a secondary branch line, and the primary branch line and the secondary branch line are respectively connected to the backplane slots. Specifically, the management power supply is sequentially input through the bus, the primary branch line, and the secondary branch line. to the...

Abstract

The invention discloses a power supply system of MicroTCA, which comprises a power supply device and a wire that is positioned on a back plate and is connected with the power supply device and a back plate groove, the wire comprises a bus connected with the power supply device and branch wires which are divided by the bus and are connected with the back plate groove; the power supply device comprises a circuit switching module used for switching external power supply input into a management power supply and inputting the management power supply into the wire, and the wire used for receiving the management power supply through the bus and outputting the management power supply to the back plate groove through the branch wires. The technical scheme can simplify the management complexity of the power supply system of MicroTCA, and lower the system cost.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a MicroTCA power supply system and a transmission method for managing power supply. Background technique [0002] Micro Telecommunication Computing Architecture (Micro Telecommunication Computing Architecture, MicroTCA) uses standard Advanced Mezzanine Card (AMC) modules to build a small-capacity and low-cost modular communication platform, which is mainly used in small telecommunications in the central office (Central Office) equipment or enterprise-class communications equipment. [0003] MicroTCA system structure such as figure 1 As shown, the system includes: a power module (Power Module, PM), a MicroTCA management switching module (MicroTCA Carrier Hub, MCH), AMC and a fan module (Cooling Unit, CU). [0004] refer to figure 2 , the MicroTCA power supply system adopts a star architecture, and the power module PM mainly includes a power conversion module, an enhanced...
