Electronic detonator initiation system achieving communication through repeater and control method of electronic detonator initiation system

Abstract

The invention discloses an electronic detonator initiation system achieving communication through a repeater and a control method of the electronic detonator initiation system. The repeater and a coder are in wireless communication with a detonation controller, the repeater is in wired communication with an electronic detonator through a signal bus, and a power source is provided for the electronic detonator; meanwhile, wireless communication signals coming from the detonation controller and the coder are transferred to the electronic detonator in a wired communication signal manner, and feedback information, responding to various commands of the detonation controller and the coder, of the electronic detonator is returned to the detonation controller and the coder in a wireless communication signal manner; wireless transmitting-receiving units and the power sources of multiple electronic detonators are integrated to the repeater, the cost of signal electronic detonators is reduced, hardware circuits of the electronic detonators are simplified, and the working reliability of the electronic detonator initiation system is improved; and meanwhile, the friendliness to the detonation surrounding environment is improved, the signal transmission distance of detonation networks of the repeater is increased, and the coverage scope of detonation zones when one-time detonation operation is implemented is expanded.

Description

technical field [0001] The invention relates to the detonation technology of pyrotechnics, in particular to an electronic detonator detonation system and its control method through repeater communication. Background technique [0002] Electronic detonator is the main detonating material of a blasting project. Its function is to generate detonation energy to detonate various explosives, detonating cords and detonators. It is also called digital electronic detonator, digital detonator or industrial digital electronic detonator. The electronic control module controls the detonation process of the electric detonator, which can realize the control of the detonation process through logic control and two-way communication, and prevent illegal detonation. [0003] Existing electronic detonators usually use traditional physical wire connections to communicate information between the detonator and the controller. The traditional physical wire connection connects all electronic detona...

Problems solved by technology

[0004] However, in the existing design of the wireless electronic detonator detonation system, each wireless electronic detonator needs to be equipped with an independent power supply. Wireless communication signal transceiver unit, so when carrying out blasting operations, the project site preparation cycle and manual workload are increased

The structure and circuit of the single-shot wireless electronic detonator are more complicated than the traditional wired electronic detonator, but its working reliability cannot be guaranteed at the same time, and the cost of the single-shot wireless electronic detonator is much higher than that of the traditional wired electronic detonator.
