[0002] At present, electronic detonators are widely used in tunnel excavation, hazard removal blasting, demolition blasting, ore-rock separation, open-pit mine blasting and other occasions. The existing electronic detonators are mainly wired electronic detonators. The wired electronic detonators mainly include foot wires, control modules, ignition bridge wires with ignition powder, basic powder and basic tube shell, etc. The wired electronic detonators communicate through wired communication. It is necessary to use a sufficiently long wire to connect the wired electronic detonator to the electronic detonator initiator. The detonation control data sent by the electronic detonator initiator is transmitted to the control module set on the wired electronic detonator through the wire, so that the electronic detonator initiator controls the wired electronic detonator to implement the blasting operation. Among them, the control module is mainly composed of an integrated control chip connected to the circuit board. , igniter, energy storage capacitor, etc.; this wired communication connection method is suitable for general onshore blasting scenarios, but when used for underwater blasting operations, the wired electronic detonator needs to be arranged underwater, and the wires used to connect the wired electronic detonator and the electronic detonator initiator are prone to waterproof failure, resulting in all or part of the control modules set on the wired electronic detonator being unable to receive the initiation control data, and then causing all or part of the wired electronic detonators connected to the waterproof failed wires to refuse to explode; in addition, the wires connected between the wired electronic detonator and the electronic detonator initiator are easily broken under the action of water flow and waves, making it difficult to ensure that the control module on the wired electronic detonator can receive the initiation control data.
