  • Wireless detonator, wireless detonation system, and wireless detonation method
    Patent number: 10584949
    Abstract: A wireless detonator (10) includes a detonation side receiving antenna (11), a detonation side transmitting antenna (18), an initiator (14) and a detonation side electronic circuit. The detonation side receiving antenna (11) receives energy for driving the detonation side electronic circuit, a control signal and an initiation signal. The detonation side electronic circuit receives the energy, the control signal and the initiation signal via the detonation side receiving antenna (11), transmits a response signal via the detonation side transmitting antenna (18) and ignites the initiator (14) in accordance with the initiation signal. A response frequency of the response signal is set to be greater than or equal to 100 MHz and less than or equal to 1 GHz.
    Type: Grant

  • Wireless detonation system, wireless detonation method, and detonator and explosive unit used in same
    Patent number: 9709373
    Abstract: A wireless detonator is provided with: a detonation part; a control part for igniting the detonation part, the control part being connected to the detonation part; a tube for accommodating the detonation part and the control part; and a detonation-side antenna used by the control part for wireless communication and capable of being used for sending and receiving without separately having a transmission-only antenna and a reception-only antenna; the detonation-side antenna being a soft magnetic body coil antenna, and the control part receiving, via the detonation-side antenna, a transmission signal at an operating frequency of 100-500 KHz.
