Frequency diversity remote controlled initiation system |
摘要 |
A blasting system includes a wireless link between a blast controller and a plurality of electronic detonators. Each detonator includes a respective electronic initiator and an explosive charge. Charge storage devices of the initiators are chargeable by a carrier of a first signal having a first frequency (f 1 ) in the order of 400 MHz-500 MHz and which is broadcasted by the blast controller. Each initiator further includes logic circuitry driven by a clock signal which is derived from the first signal and having a clock frequency of about 4 kHz, which is substantially less than the first frequency.
