AI Technical Summary
In complex underground environments, open-ground wireless electronic detonators have limited signal transmission capabilities, making it difficult to achieve reliable long-distance communication and control. They are also susceptible to electromagnetic interference, which affects the safety and reliability of blasting operations.
It adopts a ground-penetrating wireless electronic detonator detonation control device, which uses low-frequency signals to penetrate soil or rock. The signal power is amplified and transmitted over long distances through a relay transceiver module, MCU control module, power amplifier module and ground-penetrating transmitting antenna. Combined with encryption and decryption units, it ensures communication security.
It achieves reliable long-distance communication and precise detonation control in complex underground environments, overcoming the signal attenuation and interruption problems of open-ground detonators under electromagnetic interference, and improving the safety and reliability of blasting operations.
