In recent years, international and domestic terrorist activities have been active, and major and vicious terrorist incidents have occurred frequently. Reliable power supply is related to social stability. As the main power equipment, power grid facilities are easily targeted by terrorists and are key targets of prevention. Counter-terrorism tasks are heavy and responsible. big. Therefore, it is particularly necessary to equip switch stations and substations with unmanned aerial systems.
Drone drive away
At present, the anti-UAV technology of various countries is mainly divided into three categories. The first is the interference blocking category, which is mainly realized through technologies such as signal interference and sound wave interference. The second is direct destruction, including the use of laser weapons and drones. The third is monitoring and control, which is mainly realized by hijacking radio control. The second type of technology is mainly used in the military field and is the first type of fixed UAV equipment of China Southern Power Grid.
At present, the control of UAVs mostly uses radio communication technology. By transmitting high-power jamming signals to the target UAVs and suppressing the control signals, the UAVs can be forced to land or return by themselves. The electronics we introduced for landing drones take advantage of this principle. This one installs an electronic drone jammer on the frame of the step. Once the trigger is pulled, the jammer will send a full-band jamming signal to the drone, making the drone out of the control of the operator and unable to receive control. signal and automatically land on the ground. Spokesman Li Xiaolin said that once the drone's signal is in chaos, it usually has three options: fall to the ground, return to the operator, or descend smoothly. The effective range of this step is 1000 meters.
Electromagnetic suppression system
The electromagnetic suppression system can lock and attack the target in a moving state, cut off the communication connection between the small UAV and the GPS satellite signal, the communication signal with the remote control and the image transmission signal, and smoothly suppress the landing of the UAV.
Power grid equipment and substations are important facilities of a country, and their security level is no less than that of a theater command. The safety system of electrical equipment is related to social stability and national security. If it is not well protected, no one can afford the consequences. Therefore, under the trend of continuous updating of new technologies, every country should deploy a large number of advanced weapons around power facilities, monitor and give early warning to UAVs in real time, and strengthen daily management norms. It is not difficult to attack them. Dot.
