[0002] During the hoisting process of the gates of large hydropower stations, a hooking and unhooking beam is required to be used to hook and unhook the gates underwater. The upper end of the automatic hooking and unhooking beam is connected to the pulley of the gantry hoist, and the lower end is unhooked from the gate underwater to complete the lifting action. At present, the mechanical automatic hooking and unhooking beam and the hydraulic automatic hooking and unhooking beam are gradually replaced by the newly proposed electromagnetic automatic hooking and unhooking beam. The electromagnetic automatic hooking and unhooking beam uses electromagnetic magnetism to attract or release the gate to realize the hoisting of the gate, which changes the hooking and unhooking mode of the traditional automatic hooking and unhooking beam with horizontal pins.

[0003] Because the electromagnetic automatic hanging and detaching beam is set underwater and works with the gate, the operator needs to transmit the control signal to the underwater through the control device to control the electromagnetic automatic hanging and detaching beam equipment. The current control equipment usually uses radio electromagnetic wave signals for remote control. However, the internal electrode structure of the electromagnetic automatic hanging and detaching beam is extremely complex, and there may be electromagnetic interference that leads to problems such as poor control signal reception and poor response efficiency; at the same time, the automatic hanging and detaching beam needs to operate underwater, so the control signal needs to be transmitted from the air to the water, and due to water absorption and multipath effects, the amount of information transmitted by the control signal may be limited, affecting the response efficiency of the equipment. Therefore, a better electromagnetic automatic hanging and detaching beam underwater operation communication equipment is needed to solve the problem of limited communication under different propagation media.
