Paper Abstract

A fiber optics explosion primer is proposed to remove the major drawback of the electrical cable links by transmiting of the ignition primer signals through an optical fiber cable, insensitive to the electromagnetic induction generated by the atmospheric electric discharges. The primer consists of a transmitter, an optical cable and a receiver. The system has some features that assures a completely safety operation. The first feature is the signal encoding and the microcontroller supervision. Both transmitter and receiver are microcontroller assisted and all comands for the receiver operation and priming are coded and password-protected. The other feature is the absence of the power source (battery) on the receiver, preventing from accidental priming. The receiver power supply is replaced by a capacitor that is charged by the energy of the light beam coming through the optical cable to a PiN photodiode operating in photovoltaic regime. The primer operates in two steps. In the first step the capacitor is charged and all devices of the receiver are powered, while in the second step all the optical signals coming through the fiber are considered as commands. Wrong or unauthorized (nonmatching passwords) commands reset the receiver and cut off the power supply by discharging the capacitor.
