Zusammenfassung: | The invention provides an electronic detonator charging current self-adaptive adjusting method and system. The system comprises an exploder, a two-bus connected with the exploder and a plurality of electronic detonators connected to the two-bus in parallel. The detonator adjusts the charging current in the electronic detonator chip based on the number of the electronic detonators and the bus resistance according to the loading capacity of the detonator so as to limit the maximum charging current on the bus, and the networking number of the electronic detonators can be obtained through code scanning registration before networking or online scanning after networking. And the detonator bus resistance can be estimated by utilizing more than two feedback current gears in the electronic detonator chip. A plurality of charging current gears are designed in the electronic detonator chip, and selection of the feedback current gears and the charging current gears can be realized through instructions issued by an explod |
