The present invention provides a 3D visual intelligent simulation monitoring system and a simulation display method thereof, comprising a plurality of monitoring devices and at least one central control device. The monitoring devices capture video screens and generate a plurality of image signals to the central control device. A signal receiving unit of the central control device receives the image signals of the monitoring devices and transmits to an operational simulation unit, and the operational simulation unit operates the image signals with a location data and a geographic data incorporatively and generates at least one 3D simulation image. Thereby monitoring personnel can directly monitor with the 3D simulation image of the central control device, thus achieving comprehensive viewing and perfect monitoring, and functions of responding and manipulating at the first instant through the central control device.
