Description

technical field [0001] The invention belongs to the technical field of safety design of an electronic detonator detonation system, and in particular relates to a safety network device for an electronic detonator detonation system and a method for using the same. Background technique [0002] In the existing electronic detonator detonation system, usually the detonator of the electronic detonator is directly connected with the electronic detonator, or the detonator of the electronic detonator is connected with the electronic detonator through a repeater and / or a network device. [0003] In the way in which the detonator is directly connected to the electronic detonator, both the detonation voltage (charging voltage) and the communication voltage of the electronic detonator are provided by the detonator, and there is an intrinsic safety problem. That is, during the electronic detonator communication process, if the detonation voltage is charged into the electronic detonator, i...
