Remote centralized control monitoring display system

The invention relates to a remote centralized control monitoring display system. The system comprises a loop-through hard disk video recorder, a display, four four-frame control systems, four four-frame dividers, four monitors and a computer, wherein front-end 16-path video signals are connected with the four four-frame dividers through the loop-through hard disk video recorder and the display, the four four-frame dividers are respectively connected with the four monitors, the computer is connected with the four four-frame control systems, and the four four-frame control systems are respectively connected with the four four-frame dividers. The system has advantages of high display real-timeness, low cost, small occupation space and flexible and reliable control mode and is suitable for a segment market with limited space, restricted cost and high display real-timeness requirements on medium and small monitoring system control chambers. An RS485 bus communication mode is employed, problems of error operation a
