Special configurable 3U CPCIE CPU board

Abstract

The invention belongs to the field of industrial CPCIE systems and relates to a special configurable 3U CPCIE CPU board. The special configurable 3U CPCIE CPU board comprises a CPCIE interface loading board, various on-board interfaces, a CPU core module, a cooling fin, a 2.5'' hard disk, a hard disk frame, an upper interface board, a CPCI panel, a panel interface and a CPCIE interface, wherein the CPCIE interface loading board is a standard 3U CPCI board card and mainly bears other components and leads out various signal interfaces; the upper portion of the CPCIE interface loading board is directly connected with the CPU core module through a connector directly; various signals of the CPU core module are led to the on-board interfaces, and other signals are led to the interface of the upper interface board. The special configurable 3U CPCIE CPU board is mainly divided into two interface boards and one CPU core module, so that after division, any one of the two interface boards and the CPU core module needs to be changed and configured again, the other two do not need to be changed, the cost is lowered, and use is convenient.

Description

technical field [0001] The invention belongs to the industrial CPCIE (Compact Peripheral Component Interconnect Express, CPCIE for short) system field, and relates to a 3U configurable special CPCIE CPU board. Background technique [0002] The characteristics of Hot Swap, high openness, high reliability and robustness of the CPCI (Compact Peripheral Component Interconnect) system make it widely used in the field of industrial control. As time goes by, CPCI The PCI bus in the system is replaced by the more advanced and faster PCI Express, and CPCIE is the PCI Express bus used, which is the product of the CPCI system upgrade. At present, there are few CPU boards used in the CPCIE system field in China, and most of them adopt the integrated design, the boards are relatively large, and the application of 3U CPCI boards is relatively small, because the area of ​​3U standard CPCI boards is relatively small, the design The CPU board of a single board is highly integrated and diffi...

Problems solved by technology

At present, there are few CPU boards used in the CPCIE system field in China, and most of them adopt the integrated design, the boards are relatively large, and the application of 3U CPCI boards is relatively small, because the area of ​​3U standard CPCI boards is relatively small, the design The CPU board of a single board is highly integrated and difficult. Because of the small area, the interfaces that can be provided on the board are relatively limited. Generally, the external interface is placed at the position of the CPCI board baffle. If it is a single-layer CPU board , can also be placed in a row, which has great limitations; in addition, if the design of the CPU board interface and so on is a whole, when a small change is required in a certain aspect, the entire CPU board needs to be redesigned. To re-manufacture and test verification, a lot of time, effort and money are wasted
