Abstract

The invention relates to the technical field of computer application, and discloses a dual-computer hot standby control method and system supporting PPT demonstration, and the system comprises a screen connection processor, two PPT playing workstations, a control host, a page turning pen, and a plurality of splicing screens. The two PPT playing workstations comprise a main PPT playing workstationand a standby PPT playing workstation; the two PPT playing workstations are respectively connected with the screen connection processor; the screen connection processor is connected with the pluralityof spliced screens; and the screen connection processor is used for splicing the plurality of spliced screens into a large screen and managing video signal switching. According to the invention, theplaying states of the two PPT workstations are synchronized in real time, the host is controlled to monitor the playing state of the main PPT playing workstation in real time, the abnormal playing condition is accurately judged, manual monitoring and processing are not needed, and the response is quick. According to the invention, adverse effects caused by equipment faults during reporting demonstration are avoided, and the overall high availability of the system is improved.

Description

technical field [0001] The invention relates to the technical field of computer applications, in particular to a dual-computer hot standby control method and system supporting PPT demonstration. Background technique [0002] Enterprise users will start the presentation of the PPT containing business content on the workstation and put it on the large screen of the command center. The effect of playing the PPT on the large high-definition screen is very shocking and can give visitors a good communication effect. [0003] The existing technology can use dual signal sources as a backup solution for the splicing screen, but it cannot achieve the goal of high availability. It still needs to manually judge whether to switch to the backup device, and manually switch the device. The effect brought about by this is that in the presentation report scene, if the PPT software fails to turn pages, the workstation is black screen, etc., the staff will respond on the spot and switch the sig...
