Embodiment Construction

[0041] In the embodiment of the present invention, in order to simplify the power management complexity of the PM to the AMC, the PM provided to the AMC is connected to more than one AMC, and the PM needs to detect the hot plug state of the AMC. When each AMC is plugged in stably, according to The AMC plug-in signal from the bearer management unit commands the enable signal to provide 3.3V power for the AMC.

[0042] image 3 It is a schematic diagram of the system structure of the embodiment of the present invention. see image 3 As shown, in the embodiment of the present invention, the MicroTCA system includes more than one AMC, a first PM, and a bearer management unit. The bearer management unit is connected to the first PM, which is not shown in the figure. When the more than one AMC includes at least two AMCs, the first PM may be connected to the at least two AMCs through a bus topology. Since the bus topology is used to connect to the at least two AMCs, backplane res...

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...
