Abstract: In view of the problem that the location of the operation and maintenance personnel and emergency leading group of the railway bureau group were located in two places and there was no shared visual interface with the computer room monitoring center, this article designed a visual emergency monitoring and early warning system for railway information center. The system adopted IPKVM, large screen display, audio and video transmission and other technologies. It solved the problem that daily operation and emergency command and disposal were restricted by region and could not share operating system. The practice proves that the proposed system can meet the management requirements of quick response and quick disposal of emergency work, and can greatly improve the timeliness of railway information system network monitoring and early warning and emergency disposal.
