FPGA-Based System for Velocity of Detonation Measurements on Detonating Cords

Abstract

This work presents the most important aspects of the development of a system designed to measure the velocity of detonation (VOD) of detonating cords used in the mining industry. The system utilizes the point-to-point measuring method, employing optical fibers as sensing elements. It comprises an FPGA device that enables the implementation of a multi-channel, easily scalable system, and a microcontroller that manages the user’s interface. This instrument was developed in response to a request from a detonating cords manufacturing company, addressing the absence of such equipment in the national market. The VOD meter developed is capable of measuring velocities greater than 7500 m/s, covering most applications in the mining and oil industry.
