Micro telecommunication and computer general hardware platform architecture system and electric power control method

Abstract

The invention discloses a micro telecommunication and computation general hardware platform architecture (MicroTCA) system, which simplifies the complexity of power management of a PM on AMCs. The system comprises a first MicroTCA power module (PM) and more than one advanced mezzanine card (AMC), wherein the first power module PM comprises a 3.3V power control circuit, an AMC control unit and a 3.3V power control unit; the AMC control unit is used for detecting whether a corresponding AMC is stably inserted according to a PS1intersecting parallels port of each AMC, and enabling an enabling signal according to an AMC stable insertion signal command of a load management unit when the AMC is stably inserted; the 3.3V power control unit controls the 3.3V power control circuit according to the enabling signal when the AMC is stably inserted; and the 3.3V power control circuit is used for providing a 3.3V power supply for the AMC according to control of the 3.3V power control unit. Simultaneously, the invention provides a power management device and a power control method for the MicroTCA system.

Description

technical field [0001] The present invention relates to the technical field of power supply control, in particular to a small telecommunication and computing universal hardware platform architecture (Micro Telecommunications Computing Architecture, MicroTCA) system and a power supply control method thereof. Background technique [0002] MicroTCA is a general-purpose hardware platform architecture for small telecommunications and computing developed by the PCI Industrial Computer Manufacturers Group (PICMG). MicroTCA uses Advanced Mezzanine Cards (AMC) to build systems. AMCs that support hot swapping can Plugs directly into the backplane of the MicroTCA. MicroTCA mainly targets low-end, cost-sensitive telecom or computing applications that require a small physical size. The main applications include wireless base stations, routers, media gateways, etc. The name of the basic MicroTCA specification is MicroTCA.0, which defines MicroTCA's chassis structure, management, power s...

AI Technical Summary

Problems solved by technology

[0012] (1) The PM power supply control in the MicroTCA system is complicated, the connector density is high, and the PM design cost is high;

[0013] (2) PM management is complex and reliability is reduced;

The occupation of backplane resources will limit the transmission of service board signals, affect business processing capabilities, and reduce the system performance of MicroTCA

[0015] (4) The PM board needs to support the power supply of up to 16 load boards and the power on and off control of the power supply. The complexity is relatively high, which brings certain difficulties to the layout and wiring of the PM board.
