  • Publication number: 20210333078
    Abstract: Provided is a method of operating a wireless blasting system in which a blasting device and electric detonators perform communications via a wireless network. Detonator reference times of the electric detonators are synchronized with a blasting reference time of the blasting device. Communication delay times of the electric detonators are calculated. The blasting device transmits a blasting command including a blasting time to the electric detonators. Whether or not the electric detonators are ready to perform blasting is determined by determining initial input states and detonator states of the electric detonators. When the electric detonators are ready, the electric detonators perform the blasting by counting ignition initialization times thereof in which the communication delay times are reflected.
