A performance testing system based on embedded vpx board

Abstract

Examples of the present invention disclose a performance testing system based on embedded VPX board cards. The four corners of the bottom of the box have a portable foot, the bottom of the bottom of the box is equipped with a air outlet, a rowing outlet in the center of the box, and also includes control.Instruments, battery modules, VPX board cards, promotion mechanisms, heat dissipation mechanisms, regulating mechanisms, first air pumps, second air pumps, air pipes and heat dissipation ducts, multiple battery modules and VPX cards are arranged vertically in the box, along the alongsThe VPX board card arrangement has a promotion mechanism, promoting the mechanism to drive the connection with heat dissipation mechanisms and regulating agencies. One end of the air pipe is connected to the air outlet.One end of the cooling duct connects to the heat dissipation mechanism, and the exhaust air outlet is connected to the other end of the heat dissipation air duct, and a second air pump is provided on the cooling duct, the controller is connected to the first air pump and the second air pump.The design of the invention is clever, easy to use, and good cooling effect, which greatly improves the performance test accuracy of the VPX board card.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of computers, in particular to a performance testing system based on an embedded VPX board. Background technique [0002] VPX is a new generation of high-speed serial bus standard proposed by VITA (VME International Trade Association, VME International Trade Association) in 2007 on the basis of its VME bus. The basic specifications, mechanical structure and bus signals of the VPX bus are all defined in the ANSI / VITA46 series of technical specifications. VPX is a new generation bus standard based on high-speed serial bus. The original purpose of this standard is to protect the users of VME bus, inherit and continue VME bus. [0003] With the continuous development of products such as VPX reinforced motherboards, in order to meet market needs, it is necessary to test the performance of VPX boards before application. In the prior art, the VPX boards are arranged in a test box for testing...

AI Technical Summary

Problems solved by technology

In the prior art, the VPX boards are arranged and tested one by one mainly by setting up a test box, but due to the tight arrangement of the VPX boards, the heat dissipation space is small, which seriously affects the accuracy of the performance test of the VPX boards

If only a simple heat dissipation fan structure is installed on the test box, it is difficult to achieve an ideal heat dissipation effect, especially when testing a single VPX board, it is difficult to accurately reflect the heat to be tested due to the influence of self-heating and adjacent VPX boards.
