General platform system of uTCA hardware

Abstract

The invention relates to a general platform system of uTCA hardware. The system is characterized in that: the main body is a chassis; two power supply modules, an Oring circuit module for power supply redundancy configuration, a rear panel, and a uTCA carrier hub (MCH) module, asynchronous communication control modules (AMC) and a fan radiating unit arranged in parallel on the rear panel are arranged in the chassis, wherein the power supply modules are common power supply modules and arranged on the exterior of the rear panel. The number of the AMC is 1 to 12; 12 full high-size AMC board cards can simultaneously run in parallel; and the rear panel is provided with hot plug control circuits which form one-to-one corresponding control relationships together with an MCH board block, AMC board blocks and the fan radiating unit respectively. A standard uTCA power supply board card is not adopted, and the common module power supply is adopted, so that the power supply management is simpler, difficulty and cost of developing a management level with low association with the system are reduced, double-MCH module master and slave backups are supported, the reliability is enhanced, 12 full configured full high-size advanced mezzanine card (AMC) modules are supported, and the capacity of the system is improved.

Description

technical field [0001] The invention relates to a carrier-level universal hardware platform, which is based on the uTCA standard, can be compatible with standard AMC boards, reduces hardware costs, increases capacity, and greatly enhances the uTCA hardware universal platform system. Background technique [0002] As a supplement to the AdvanedTCA standard, a popular modular hardware platform standard in today's industry, the uTCA hardware technology standard is mainly aimed at applications such as network communication, medical image processing, embedded control, and military industry. Its high bandwidth, modularization, and flexibility And the advantages of high cost performance have been applied to a wider range of application fields, and become the preferred standard for building a cost-effective modular standard hardware platform today. [0003] A typical uTCA system includes: 10 AMC (Advanced Mezzanine Card) modules, 1 or 2 MCH (uTCA Carrier Hub), interconnection backpla...

AI Technical Summary

Problems solved by technology

There are also some 19-inch uTCA chassis on the market, but these products use standard uTCA power modules. Since the power module occupies the slot, these chassis can only support 10 full-height AMC boards. Although 4 A half-height AMC board can also reach the capacity of 12 AMC boards on these chassis

However, because the AMC board itself is very compact and the density of components on the board is very high, if it is to be made into a half-height size, on the one hand, the height of the components is difficult to meet the requirements, and on the other hand, it is very difficult for the half-height AMC board to dissipate heat. High-size AMC boards are very rare in the market

Therefore, the standard uTCA platform we purchased in the early stage can only use 10 AMC boards, and there are two half-height slots, so it is a waste of waste, and it does not meet the standard 12 AMC board capacity.

In the standard uTCA, the power supply
