An initiative warning system comprises a protective area for accommodating objects and defining an area network, a plurality of sensors respectively installed on the objects, a detecting mainframe connected with the area network, and a terminal communicated with the detecting mainframe through the area network. Wherein, the arrangement of the area network promotes the connection between the detecting main frame and substitutes the conventional wiring allocation, so as to streamline installations of the detecting mainframe and the sensors. Additionally, the sensors can regularly transmit oscillating signals to the detecting mainframe for a further recognition and comparison. Thus, a controlling signal would be timely sent to trigger a warning command showing on the terminal through the area network when the compatible signals between the sensors and the detecting mainframe are not detected by the detecting mainframe, thereby preferably attaining an active warning effect. |
