Design of the crane anti-collision alarming system based on electric field measurement

The design of the crane anti-collision alarming system based on electric field measurement is introduced in this paper. The crane anti-collision alarming system consists of many electric field acquisition devices and an alarm device. The electric field acquisition devices are responsible for collecting the electric field value of each point. The alarming device can receive all the signals sent by the various electric field acquisition devices wirelessly, and then the different alarming information is given by judging the safe electric field value to ensure the safety of the working cranes in the occasion of the high-voltage transmission wire.
