Design and Implementation of Diamond Press'S Pressure Hammer Protection Based on Voiceprint Recognition

Abstract

In the manufacturing process of artificial diamond micro powder, if tungsten steel pressure hammer of diamond press makes a tungsten steel hammer pressure crack due to fatigue of workpiece, it is always leading to significant economic losses. The pressure hammer detection and protection device of the diamond press introduced in this paper takes advantage of the voiceprint recognition technology. Firstly, it extracts the characteristic parameters of pressure hammer breaking voice and establishes a sound pressure hammer breaking template library. And then, the paper compares the work field sound characteristic parameters of diamond press and pressure hammer breaking template library. If they are consistent with each other, the work power of diamond press will be cut down. Thus, it implements protection for the rest good pressure hammers.
