Description

Technical Field

[0001] The present invention relates to the technical field of multi-screen management, and in particular to a multi-screen picture display management method and system. Background Art

[0002] In the nuclear power environment, in order to facilitate the simultaneous viewing of different types of screen information (alarms, trends, logs, etc.), a host needs to use multiple monitors; however, traditional multi-screen display management has some defects and does not support adaptive adjustment of the number of screens and screen resolution. When the number of on-site screens or the resolution changes, serious problems such as monitoring screen offset, overlap, exceeding the screen range, and display confusion will occur, and they cannot be restored online.

[0003] The existing multi-screen management solution uses logical IDs to distinguish different screens. However, when the number of screens changes, the logical IDs will be reallocated, the screen coordinates will change, and the monitoring screen will shift during operation, resulting in overlapping and chaotic display.
