High-precision detonator blasting system based on electronic delay body

Abstract

The invention discloses a high-precision detonator blasting system based on an electronic delay body. The high-precision detonator blasting system comprises a detonating primer and an electronic delay body detonator which are connected through a power line. In order to keep the simplicity and reliability of the blasting system, a communication protocol method is not adopted between the detonating primer and the electronic delay body detonator to control the detonation of the electronic delay body detonator, and the detonation is realized through state recognition only. By adoption of the electronic delay body, a chemical delay agent is replaced, and the chemical agent pollution in the production process and the lead pollution in the blasting site are eliminated; by adoption of an open source commerce (OSC) oscillator, the precision of 99 percent can be achieved by utilizing laser correction; and due to the mode of reducing the voltage of the power line, the state recognition is realized, a fixed time period T is kept, at the moment that the fixed time period T is kept, each electronic detonator is started and timed, and the high-precision delay of the system is guaranteed.

Description

technical field [0001] The invention relates to the field of pyrotechnics and electronic technology, in particular to a high-precision detonator blasting system based on an electronic delay body. Background technique [0002] Most of the current delay detonators use chemical delay agents. By adjusting the formula of the agents, the lead tubes are filled and stretched multiple times to form multi-core lead extensions, which are then cut, loaded into the detonators, pinched at the waist, and assembled into delay detonators. According to the characteristics of the delay of chemical agents, several time periods have been formulated to achieve different delay times. Due to the discrete nature of chemical agents, there is a large deviation in the delay time between the extension bodies of the same length, and the delay detonators often appear in series during high delay periods, resulting in product scrapping. In addition, lead pollution caused by chemical delay agents is very se...
