Title: Metal protective net and protection monitoring system

Abstract: The present invention relates to a metal protective net, including: multiple steel wires arranged in parallel; multiple metal connecting sheets arranged in parallel, where the metal connecting sheets and the steel wires are arranged to intersect with each other at multiple intersections without being connected; insulating members which are provided between the steel wires and the metal connecting sheets and located at the intersections, and fixedly connected therewith; and connecting terminals, where both ends of each steel wire each are connected with one connecting terminal, and both ends of each metal connecting sheet each are connected with one connecting terminal; and a monitoring device electrically connected with the connecting terminals. The steel wires and the metal sheets, which form the metal protective net, are not electrically conductive with each other, forming many individual loops. If the metal net is broken, an alarm can be sent by the monitoring device.
