Performance test system based on embedded VPX board cards

Abstract

The embodiment of the invention discloses a performance test system based on embedded VPX board cards. Support legs are arranged at four corners of the bottom end of a box body, an air inlet is arranged in the center of the bottom of the box body, an air outlet is arranged in the center of the top of the box body, the system further comprises a controller, battery modules, the VPX board cards, a pushing mechanism, a heat dissipation mechanism, an adjusting mechanism, a first air pump, a second air pump, an air inlet pipe and a heat dissipation air pipe, the plurality of battery modules and theVPX board cards are vertically arranged in the box body, the pushing mechanism is arranged along the arrangement direction of the VPX board cards, the heat dissipation mechanism and the adjusting mechanism are in transmission connection with the pushing mechanism, one end of the air inlet pipe is communicated with the air inlet, the other end of the air inlet pipe is communicated with the heat dissipation mechanism, the first air pump is arranged on the air inlet pipe, the other end of the heat dissipation air pipe communicates with the air outlet, the second air pump is arranged on the heatdissipation air pipe, and the controller is electrically connected with the first air pump and the second air pump. The system is ingenious in structural design, convenient and efficient to use and good in cooling effect, and the performance test accuracy of the VPX board cards is greatly improved.

Description

technical field [0001] The embodiment of the present invention relates to the field of computer technology, 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 based on its VME bus. The basic specifications, mechanical structure and bus signals of the VPX bus are all defined in the ANSI / VITA46 series 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 and tested one by one mainly by...

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.
