Electronic detonator capable of improving communication reliability

Abstract

The invention discloses an electronic detonator capable of improving communication reliability. The electronic detonator comprises a rectification and communication circuit, a control module, an ignition module and a switch structure, wherein the control module is connected with the ignition module and the rectification and communication circuit, the rectification and communication circuit is connected with an initiator, one end of the switch structure is connected with the rectification and communication circuit, the other end of the switch structure is connected with the initiator, the switch structure is controlled by the control module, after the control module receives an initiation instruction sent by the initiator and starts to execute initiation, the control module controls the switch structure to be in an off state, and at the moment, an electronic detonator module is physically separated from the initiator and other electronic detonator modules. According to the electronic detonator capable of improving the communication reliability, the problem that when the electronic detonator is used in complex scenes such as a small section, a metal mine, a downhole and a tunnel, theelectronic detonator refuses to detonate due to electric signal interference in the process of receiving the initiation instruction and executing initiation is solved, and the communication reliability and safety of the electronic detonator are greatly improved.

Description

technical field [0001] The invention relates to an electronic detonator, in particular to an electronic detonator with improved communication reliability. 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 basically consists of a detonator and a detonator. Multiple electronic detonator modules are connected to the detonator in parallel. The detonator can simultaneously control multiple electronic detonators to work. [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 sectio...

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.
