Abstract

The invention relates to a multi-computer display control switching method for a VPX case, and belongs to the technical field of VPX module display control. According to the invention, a computer module is connected with an exchange board module, a DP display switching module and a USB switching module in the exchange board are utilized to realize a function of multi-input and one-output of display control signals, and the output single display control signal can be connected to display control equipment (a keyboard, a mouse and a display) for testing and debugging, so that the debugging and operation convenience of multiple computer modules of the VPX case is improved. By means of the method, the use amount of display control equipment in the debugging process of the multi-computer moduleVPX case is reduced, and the demand for display control debugging interfaces of the VPX case is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of VPX module display and control, in particular to a multi-computer display control switching method for a VPX chassis. Background technique [0002] With the development and progress of science and technology, the performance and integration requirements of computers in various fields are getting higher and higher. It is necessary to integrate multiple independent computer modules in one device to complete their own independent tasks. It has the advantages of high-speed interconnection bus and Highly integrated VPX-based computer cases are increasingly being used in military, aerospace and other high-end fields and various industries. However, high integration has brought great difficulties to the overall debugging of the system. In order to debug each computer module in the system online, it is often necessary to connect the display control signals of each computer module, keyboard and mouse, etc. to the ...
