Method and jig for automatically detecting open pluggable interfaces of video output devices

Abstract

The invention discloses a method and a jig for automatically detecting open pluggable interfaces of video output devices. The method includes electrically coupling an open pluggable interface of a video output device to an open pluggable interface of the jig at first; enabling a video processing unit to receive an acknowledgement signal from the video output device after the jig is started up; then outputting a high-definition multimedia interface signal and a test signal to the open pluggable interface of the jig; requesting the video output device to transmit information via the open pluggable interface of the video output device; enabling the video processing unit to detect the open pluggable interface of the video output device and determine whether the open pluggable interface of the video output device is normal or not according to the information which is transmitted back to the video processing unit; outputting a screen display picture to the video output device and displaying a detection result. The jig further comprises the video processing unit which is electrically coupled with the open pluggable interface of the jig. The information is relevant to the received signals.

Description

technical field [0001] The invention relates to a detection method and a jig, in particular to a method for automatically detecting an open easy-to-plug interface and a jig. Background technique [0002] The existing factory production line produces electronic billboards with open pluggable interfaces. When detecting the open pluggable interfaces of electronic billboards, the host is provided with the information of the existing billboards with open pluggable interfaces, such as Personal computers, minicomputers, set-top boxes, etc. for testing. This kind of detection method needs to wait for the billboard information to provide the mainframe to be turned on, and then manually select each function option in the on-screen display (OSD) interface to confirm whether the signal pins of the open easy-to-plug interface of the electronic billboard are correct one by one. All function normally. And whenever an electronic billboard is detected, it is necessary to shut down the host...

Problems solved by technology

And whenever an electronic billboard is detected, it is necessary to shut down the host computer that provides the billboard information first, and then restarts the host computer that provides the billboard information after connecting the next electronic billboard to be detected. It takes a long time to carry out detection, and because the detection process cannot exclude human factors, it is easy to lack accuracy
