When the grounding wire is illegally stolen, the sensing loop is immediately cut off, and an alarm signal is generated to carry out remote alarm. Compared with the current transformer used as the anti-theft cutting sensor, the method has high concealment, low cost, simplicity and easy implementation and good anti-theft effect on the anti-theft cutting of the grounding wire.
Fig. 10 is a schematic structural view of an anti-theft cutting sensor for a ground wire according to another exemplary embodiment of the present application. As shown in fig. 10, the ground wire anti-theft sensor includes a magnetic switch provided on the ground box, and generates alarm information when the magnetic switch is separated.
For the anti-prying of the grounding box, a magnetic switch is adopted as a sensor. Under normal conditions, the grounding box is in a closed state, and when an illegal person prizes the grounding box to break, the magnetic switch can be separated, so that an alarm signal can be timely generated.
In one embodiment, the monitoring terminal may include an infrared sensor disposed in the power tunnel that generates an alarm message when the infrared sensor is triggered.
The infrared sensor includes an optical system, a detection element, and a conversion circuit. Optical systems can be classified into transmission type and reflection type according to their structures. The detecting elements can be classified into thermosensitive detecting elements and photoelectric detecting elements according to the working principle. The most commonly used thermistors are thermistors. When the thermistor is irradiated by infrared rays, the temperature rises, the resistance changes, and the temperature becomes an electric signal output through a conversion circuit. The photodetection element is usually a photosensitive element, and is usually made of materials such as lead sulfide, lead selenide, indium arsenide, antimony arsenide, ternary mercury cadmium telluride alloy, germanium and silicon doping. When illegal personnel enter the electric power tunnel, the installed infrared triggering sensor generates an alarm signal to inform the monitoring platform. Meanwhile, the body temperature of the human body is about 36-37 ℃, and far infrared rays with the peak value of 9-10 mu m are emitted, so that the far infrared rays can be set and removed through a system, and the situation of false alarm is greatly avoided.

The electronic fence is an active intrusion crossing-preventing fence, and is used for countering an intrusion attempt, knocking back an intruder, delaying the intrusion time, not threatening the life of a person, and sending an intrusion signal to a monitoring platform so as to ensure that a manager can know the condition of an alarm area in time and quickly process the situation. The solar battery mainly comprises a solar controller (a photovoltaic controller, a wind-light complementary controller, a solar storage battery and a solar inverter).
In one embodiment, the communication sub-center transmits the alarm information by adopting an ISM band wireless digital transmission mode.
