Abstract

The invention relates to a man-machine display control signal remote transmission method for a 6U VPX computer module, and belongs to the technical field of VPX module display control. The signal enhancement modules are respectively added on the VGA and PS / 2 display control interfaces of the computer module, so that the signal driving capability is improved, and the function of remotely transmitting the VGA and PS / 2 signals in a display control manner is achieved. The technology can meet the application requirements of the display control signals of the computer module on the far-end display control equipment, and is suitable for the scenes that the 6UVPX computer module and the display control equipment need to be arranged and used in a long-distance distributed manner. The transmission distance of the display control signal cable can reach more than 20 meters. The technology can meet the application requirements of computer module display and control signals on far-end display and control equipment, and is particularly suitable for the scenes that computers and display and control equipment need to be arranged and used in a long-distance distributed mode.

Description

technical field [0001] The invention relates to the technical field of VPX module display and control, in particular to a method for remote transmission of man-machine display and control signals for a 6U VPX computer module. Background technique [0002] With the development and progress of science and technology, the requirements for computer performance in various fields are getting higher and higher. In some special application fields, the computer and the display and control equipment need to be placed in different spaces, which makes the distance between the display and control equipment and the computer The cable length exceeds the limit length. For VGA and PS / 2 and other display control signals, the cable length generally does not exceed 5 meters. If the signal cable length exceeds the limit value, the video will be unstable and the display quality will be lower than that of the PS / 2 keyboard. , The mouse cannot be recognized and other problems.
