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 communication process of the electronic detonator, if the communication voltage is charged into the electronic de...

AI Technical Summary

Problems solved by technology

That is, in the process of electronic detonator communication, if the communication voltage is charged into the electronic detonator, it is easy to cause the electronic detonator to explode by mistake, resulting in safety accidents

[0004] In the way that the electronic detonator is connected to the electronic detonator through a repeater and / or a network device, although the detonation voltage and the communication voltage are provided separately, this connection method cannot fundamentally solve the security problem. In addition, with the increase of the network scale The number of repeaters and / or network devices is also increasing, which increases the cost of network deployment
