A stereographic network monitoring system is provided to display a stereographic representation of an abnormal unit in a controlled device monitored via a network, wherein the stereographic representation shows the abnormal unit and its relative position, so that a supervisor can be clearly informed the relative position of the component inside the controlled device and promptly take appropriate measures to remedy. This system includes a monitoring server, a database, at least a controlled device, a network unit and a display unit. The monitoring server is connected to the database and controlled device via the network unit. When the controlled device sends an abnormal message to the monitoring server, it can retrieve the device stereogram and basic data of the unit components of the controlled device for display in the displaying unit.
