Electronic detonator detonation control method, device and system

Abstract

The invention discloses an electronic detonator detonation control method, device and system. The method comprises the steps of receiving a detonation instruction sent by a control device, wherein the detonation instruction comprises sequence information of the detonation instruction being sent; calculating initiation starting time according to the sequence information; and when the detonation starting time is reached, triggering detonation to be started, wherein the detonation instruction is sent by control equipment for multiple times, the sequence information corresponds to the number of times of sending the detonating instruction, and the detonation starting time is preset time after the last time of detonation instruction is sent. Therefore, the situations of missed explosion and wrong explosion of a detonator due to missed collection or wrong collection of the detonation instruction by the detonator are effectively avoided.

Description

technical field [0001] The invention relates to the field of electronic detonators, in particular to an electronic detonator detonation control method, device and system. Background technique [0002] The master control device (detonator) needs to communicate with the slave device (electronic detonator) for parameter configuration and verification, and finally sends a detonation command to notify all detonators to detonate. The network of the master-slave device is a parallel network. The master control device connects two twisted-pair wires, which are usually called busbars; all slave devices lead out two short wires, usually called leg wires; all slave device leg wires are connected to the busbar in parallel form a network. The master device communicates with each slave device serially, conducts a session, and completes the configuration and verification of the slave devices one by one. Due to the complex environment of the electronic detonator construction site, the len...

AI Technical Summary

Problems solved by technology

However, the final detonation command is a group command, all slave devices (electronic detonators) receive the command together and respond at the same time, and there is no response to the command

Therefore, after the main device sends out the detonation command, it cannot confirm that each detonator has received the detonation command

If hundreds of detonators connected to a bus are affected by interference, there will be a certain probability that the detonators will not receive the detonation command correctly, resulting in missed explosions and wrong explosions, which will affect the blasting effect and threaten production safety to a certain extent.
