Detonator blasting system based on electronic delay body

Abstract

The invention discloses a detonator blasting system based on an electronic delay body. The detonator blasting system comprises a detonating primer and an electronic delay body detonator which are connected through a power line, wherein the electronic delay body detonator replaces a chemical delay agent by employing the electronic delay body, and the chemical agent pollution in the production process and the lead pollution in the blasting site are eliminated; and meanwhile, in order to keep the simplicity and reliability of the blasting system, a complex communication protocol is not adopted between the detonating primer and the electronic delay body detonator, the detonating primer starts to supply power, the electronic delay body detonator starts self-checking, a self-checking state output circuit respectively switches different circuits in the self-checking process and during normal and abnormal self-checking under control of a digital control circuit, so that the current on the power line is changed, and the detonating primer obtains the state of the electronic delay body detonator through a mode of detecting the current on the power line; and therefore, the problem that the conventional detonator system communicates through a complex communication protocol so as to cause complicated redundancy of the system is solved.

Description

technical field [0001] The invention relates to the field of pyrotechnics and electronic technology, in particular to a 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 serious. [0003...
