Monitoring and early warning system for preventing power transmission line from intrusion of external force

The utility model discloses a monitoring and early warning system for preventing a power transmission line from the intrusion of an external force. The system comprises two parts, namely a hardware system and a monitoring center. A precise microwave radar in the hardware system acquires an external force invasion signal of the power transmission line. A fixed camera acquires a video image signal of a monitoring area. The acquired signals are sent to a computer of the monitoring center by wireless communication modules. After the signals are processed by monitoring software, if the external force invasion exists, the monitoring center sends an instruction to allow an audible and visual alarm to work. Meanwhile, monitoring personnel are informed by a short message or a multimedia message to talk in the monitoring center and remind suspicious personnel to depart from a dangerous area through the output of a talking loudspeaker. According to the technical scheme of the utility model, due to the adoption of the sy
