Problems solved by technology

[0003] When the number of electronic detonators in the network is large, the charging time is long, and the charging time interval between the first and the last two electronic detonators is longer, and each electronic detonator needs to be operated separately, which increases the probability of failure to detonate when the charge is not enough; The charging voltage is judged by the first detection, and the whole voltage division is used for charging. The charging voltage at each stage must control the charging current. If the voltage division method is adopted, the operation instructions are extremely complicated, the charging process is more cumbersome, and the charging time is longer. Homework adds more uncertainties

Embodiment 1

[0034] Such as figure 1 As shown, this embodiment provides a segmented charging method for electronic detonators in a networking state. The segmented charging method for electronic detonators is used to charge the capacitors of electronic detonators in the electronic detonator network. The electronic detonators also include a charging switch. The switch is connected in series with the capacitor, and when the capacitor is charged, the charging switch is closed. The electronic detonator network includes n electronic detonators connected in parallel to the same electronic detonator detonator, and each electronic detonator is numbered 1 to n in turn. Before charging the capacitor of the electronic detonator, a preset voltage should be set on the capacitor as a basis for judging whether the capacitor is fully charged: when the charging voltage of the capacitor reaches the preset voltage, the capacitor is fully charged.

Abstract

The invention discloses a segmented charging method for electronic detonators in a networking state and electronic detonator networking, relates to the technical field of electronic detonators, and is used for charging the capacitance of electronic detonators in the electronic detonator networking, including the following steps: Choose one of the capacitors from 2 to n‑1, charge the selected capacitor to n capacitors; choose one of the uncharged capacitors, charge the selected capacitor to n capacitors; repeat the previous Steps until the capacitors numbered 1 to n are all charged. The method provided by the invention not only shortens the charging time, but also does not need cumbersome operation instructions under the premise of ensuring the blasting probability.

Description

【Technical field】 [0001] The invention relates to the technical field of electronic detonators, in particular to a segmented charging method for electronic detonators in a networking state and a network of electronic detonators. 【Background technique】 [0002] With the continuous development and improvement of electronic detonator technology, its technical superiority has been more and more widely recognized in the global blasting industry. The principle of detonation is to operate the electronic detonator chip to charge the energy storage capacitor through control instructions. After charging is completed The primer is ignited by a discharge to the bridge wire. In the prior art, the communication between the detonator and the electronic detonator mainly adopts parallel connection. Due to the limited output power of the detonator, if there are too many electronic detonators connected to the detonator, the excessive current will exceed the limit of the detonator output when ...
