doi:10.3969/j.issn.1000-1093.2013.08.018

Abstract

Abstract:

An ultrasonic-based detection system for detecting the broken and weak points of small-diameter lead sheathed detonating cord is proposed in view of the limited detection means, low detection efficiency and low accuracy of existing non-contact detection method for lead sheathed detonating cord. This system can meet the measurement requirements of broken and weak points of detonating cord. Experiments and practical use show that this method is feasible and can effectively improve the detection efficiency and precision, and the system runs reliably.

Key words: instrument and meter technique, detonating cord, broken and weak points detection, ultrasonic, non-contact detection
