US12480752 - Enhanced safety and reliability for a networked detonator blasting system

Ethernet systems, methods and blasting machines are presented for remote turn on of the blasting machine and reliable fire and arm commands issuance. Systems, methods, blasting machines and wireless bridge units are presented for wireless blasting for safe firing of detonators under control of a remote wireless master controller in which the blasting machine is connected by cabling to the wireless bridge unit and power to a firing circuit of the blasting machine is remotely controlled via the bridge unit. The bridge unit or Ethernet primary controller selectively provides first and second firing messages to the blasting machine contingent upon acknowledgment of safe receipt of the first firing message by the blasting machine, and the blasting machine fires the connected detonators only if the first and second firing messages are correctly received from the bridge unit.

The patent describes a networked detonator blasting system that enhances safety and reliability through Ethernet communication for remote activation and control of blasting machines. It includes protective measures against electrical effects from detonations and ensures that firing commands are only executed upon confirmed receipt of safety messages.

Claim 1

1 . A blasting method, comprising: establishing an Ethernet communication link between an Ethernet controller and a blasting machine via a switch and a router using an Ethernet address and an Ethernet communication protocol; operatively coupling a protected Ethernet connection box in one or more connection paths between the Ethernet controller and the blasting machine, including clamping elements to protect network elements including at least one of the blasting machine, the switch, the router, and the Ethernet controller against electrical after effects associated with a blast or detonation, after the communication link is established, applying power to the blasting machine; and displaying at least one function, message, or status of the blasting machine on a display associated with the controller. establishing an Ethernet communication link between an Ethernet controller and a blasting machine via a switch and a router using an Ethernet address and an Ethernet communication protocol; operatively coupling a protected Ethernet connection box in one or more connection paths between the Ethernet controller and the blasting machine, including clamping elements to protect network elements including at least one of the blasting machine, the switch, the router, and the Ethernet controller against electrical after effects associated with a blast or detonation, after the communication link is established, applying power to the blasting machine; and displaying at least one function, message, or status of the blasting machine on a display associated with the controller.
