Method and device for connecting and controlling electronic detonator priming device and electronic detonator

Abstract

An electric detonator primer and a method and a device for connecting and controlling an electric detonator. An electric detonator controller is added between the electric detonator primer and the electric detonator. Energy and a signal transferred between the electric detonator primer and the electric detonator are both forwarded via the electric detonator controller. Magnetic ring induction is adopted for transferring energy and a downlink communication signal of the electric detonator controller between the electric detonator primer and the electric detonator controller. Radio wave is adopted for transferring an uplink communication signal between the electric detonator controller and the electric detonator primer. Therefore, the wiring between the electric detonator primer and the electric detonator is simplified, a good anti-electromagnetic interference effect is achieved, and further the breakdown of the entire explosive network due to the failure of a certain electric detonator is prevented.

Description

technical field [0001] The invention relates to a method and device for controlling an electronic detonator, in particular to a method for connecting and controlling an electronic detonator detonator and an electronic detonator. Background technique [0002] At present, the magnetoelectric detonator is a kind of detonator that appeared in the early 1990s. It adopts the principle of transformer and the frequency selection characteristics of soft magnetic materials such as manganese zinc ferrite, and the product has better anti-electromagnetic interference ability. However, it has problems such as poor series reliability and poor delay accuracy. The electronic detonator is a new type of detonator that appeared in the late 1990s. It consists of an electronic integrated chip (including a communication circuit with the detonator, an electronic timing circuit), an energy storage device, an electronic ignition switch and components of the basic electric detonator. It has a two-way ...

AI Technical Summary

Problems solved by technology

However, most of the international and domestic electronic detonators that realize two-way communication with the detonator are used in parallel, and it is necessary to realize the electrical direct connection between the detonator leg and the detonator output bus. This process has many disadvantages, such as: complicated operation, large-scale The application is labor-intensive;

[0003] When the electronic detonator fails, it may generate a large consumption current. When there is such an electronic detonator in the parallel network, it may cause other electronic detonators in the same network to be unable to use normally; no matter what kind of direct electrical connection, the exposed metal contact is The place with the worst waterproof performance; the Chinese patent has published a patent application with the application number "200420104510.5", which proposes a magnetoelectric electronic delay electric detonator, and its structure shows that it is an electronic device that fails to realize two-way communication with the detonating device. The detonator cannot carry out two-way communication after the electronic detonator is installed, and it is impossible to confirm whether the electronic detonator with the installed hole is normal, and there are major defects in use

[0004] Electronic detonators need to be used in the field. If wireless control is used to detonate, the general method is to let it have a built-in battery for power supply, and turn on the battery switch when it needs to be used. However, such products are not environmentally friendly and are prone to safety problems.

There are foreign reports of electronic detonators using microwaves for detonation control, but their cost is high, and there may be dead angles in wireless communication in both directions, so the value in actual use is not high
