  • Publication number: 20240060760
    Abstract: 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.
