Abstract

Aiming at the industrial pain points that traditional blasting control equipment lacks an independent discharge output assembly and multi-channel delay initiators are short of core supporting modules, a discharge output assembly for blasting controllers with automatic high-voltage detection adapted to multi-channel delay initiators was designed. The assembly adopts a modular architecture, consisting of an output voltage circuit, a comparison and detection circuit, a dual-channel assembly interface and a discharge control unit, and is powered by a lithium battery. It can realize accurate automatic detection and real-time feedback of the discharge voltage of high-voltage capacitors as well as precise control of discharge on-off. This assembly fills the market gap, solves the problems of no voltage detection, no state feedback and poor stability of traditional circuits, and is convenient for production, installation and maintenance. It can significantly improve the discharge stability of blasting controllers, provide core technical support for the marketization of multi-channel delay initiators, and has prominent engineering application value.
