Description
Technical field
The present invention relates to a kind of carrier-class general hardware platform, this platform is based on the uTCA standard, and AMC integrated circuit board that can compatibility standard has reduced hardware cost and increased capacity, the mu TCA hardware common platform system that its practicality is strengthened greatly.
Background technology
As the popular modularized hardware platform standard of current industry--replenishing of AdvanedTCA standard, uTCA hardware technology standard mainly for be the application of network service, medical imaging processing, embedded Control and military project etc., the advantage of the aspects such as its high bandwidth, modularization, dirigibility and high performance-price ratio, be applied to more widely application, become the preferred standard of current structure high performance-price ratio modularization standard hardware platform.
A typical uTCA system comprises: 10 AMC (Advanced Mezzanine Card) module, 1 or 2 MCH (uTCA Carrier Hub), interconnection backboard and the modules such as power supply and heat radiation.The AMC integrated circuit board has four kinds of forms according to its physical size difference: single wide overall height, single wide half height, two wide overall heights, two wide half height, but in fact because factor affecting such as element height space heat eliminations, the most common with single wide overall height, the integrated circuit board of other three kinds of forms is being difficult to find trace on the market, does not generally also adopt these three kinds of modes in development.
Although the uTCA standard is not made concrete regulation to the physical construction of cabinet, 19 inches frame has been the construction standard of telecommunications room, so general telecommunication apparatus all is 19 inches width.19 inches uTCA cabinets on the market also have, what but these products all used is the uTCA power module of standard, because power module has taken the groove position, so that these cabinets can only be supported the AMC integrated circuit board of 10 overall height sizes, although use the AMC integrated circuit board of 4 half high sizes also can reach the capacity of 12 AMC integrated circuit boards above the cabinet at these.But because AMC integrated circuit board itself is just very compact, density of components is very high on the plate, be difficult to meet the requirements if make the words one side components and parts height of half high size, the AMC integrated circuit board heat radiation of other half high size is very difficult, substantially can not see so the AMC integrated circuit board of half high size is very rare on the market.So the standard uTCA platform that early stage, we bought can only use 10 AMC integrated circuit boards, there is the groove position of two and half high sizes not waste like this and says, and do not reach 12 AMC integrated circuit board capacity of standard code.All to be controlled by power module in the AMC integrated circuit board power supply of the uTCA the inside of standard, these characteristics are so that the uTCA system uses particularly troublesome, in general power supply only has been responsible for power supply just, and in uTCA system the inside, need power module and MCH, the communication of AMC integrated circuit board just to be come to power to functional module by power module later on, here relate to some more loaded down with trivial details IPMI communications protocol, so that power module is very complicated, general producer is difficult to exploitation; Could allow the AMC integrated circuit board for powering on so sometimes bring the debugging of a power panel calorie requirement long period; And the power module consultation of different manufacturers is a bit different, and is compatible bad each other, debugged one power supply integrated circuit board and must again debug with other one power module again, although standard is arranged, can each complete compatibility of actual product.
