An electronic detonator with improved communication reliability and anti-interference performance

Abstract

The invention discloses an electronic detonator with improved communication reliability and anti-interference performance, which comprises a rectification and communication circuit, a control module, an ignition module, a first switch structure and a second switch structure, and the control module is respectively connected to the ignition module and the rectification and Communication circuit, the rectification and communication circuit is connected to the detonator, one end of the first switch structure is connected to the rectification and communication circuit, the other end is connected to the detonator, one end of the second switch structure is connected between the rectification and communication circuit and the detonator, and the other end is grounded, when After the control module receives the detonation instruction issued by the detonator and starts to execute the detonation, the control module controls the first switch structure to be in the open state, and controls the second switch structure to be in the closed state, so that the electronic detonator module is connected with the detonator and other electronic devices at this time. The detonator modules are physically separated. The invention greatly improves the anti-interference performance and safety of the electronic detonator.

Description

technical field [0001] The invention relates to an electronic detonator, in particular to an electronic detonator with improved communication reliability and anti-interference performance. Background technique [0002] Electronic detonators, also known as digital electronic detonators, digital detonators or industrial digital electronic detonators, generally use electronic detonator blasting control systems to control electronic detonators for blasting. [0003] The electronic detonator blasting control system is basically composed of a detonator and a detonator. Multiple electronic detonator modules are connected to the detonator in parallel, and the detonator can simultaneously control multiple electronic detonators. [0004] Electronic detonators are generally blasted after receiving the detonation signal from the detonator. The signal transmission between the electronic detonator and the detonator is generally through wired transmission, but when used in complex working ...

AI Technical Summary

Problems solved by technology

[0004] Electronic detonators are generally blasted after receiving the detonation signal from the detonator. The signal transmission between the electronic detonator and the detonator is generally through wired transmission, but when used in complex working environments such as small sections, metal mines, underground mines and tunnels At the same time, the signal transmission between the electronic detonator and the detonator is often interfered, which leads to the problem that the electronic detonator fails to explode, which is not conducive to the safety of the electronic detonator.
