Embodiment Construction

[0045] Such as figure 1 Shown is a block diagram of the digital electronic detonator blasting system provided by the present invention. The digital electronic detonator blasting system includes a detonator 20, a programmer 30, and multiple digital electronic detonators 10, and the detonator 20, the programmer 30, and the digital electronic detonators 10 are connected by bus.

[0046]The detonator 20 is the general controller of the blasting system. First, the detonator 20 carries out blasting design for the blasting project and the scene, and designs the digital electronic detonator quantity, position and delay time of the whole blasting site. For example, the blasting design requires 500 blasting engineering. Send digital electronic detonators, choose the location of each blasting point, 500 rounds of detonators, divided into 50 groups, and the delay interval of each group is 25 milliseconds; then decompose the design content, that is, assign different digital electronic deto...

Abstract

The invention provides a digital electronic detonator blasting system and a control method thereof; the digital electronic detonator blasting system comprises an initiator, one or a plurality of programming units, and one or a plurality of digital electronic detonators; the initiator, the programming units and the digital electronic detonators are connected in a double bus way. The control methodof the digital electronic detonator blasting system comprises the following steps: self-detection of the initiator, authentication of operating personnel of the initiator, blasting design, authentication of the initiator, obtaining license information o f the initiator, data decryption of initiation, validity authentication of time and position information, self-detection of the programming unit,authentication of operating personnel of the programming unit, blasting design task decomposition, detonator charging, detection of working state of the detonator, programming, system test, initiating command authentication, synchronous test, initiating authorization verification, broadcasting initiating command and data backup.

Description

technical field [0001] The invention relates to the technical field of pyrotechnics, in particular to a digital electronic detonator blasting system and a control method thereof. Background technique [0002] The existing electric detonator detonators generally use a series or series-parallel combination electric detonator network. When thousands of detonators are connected in series, in order to ensure that all the detonators in the network can detonate at the same time, the detonator detonator should be able to generate a current of one to several amperes instantaneously. There will be phenomena such as rejection of explosion and half explosion. The resistance of a single generator detonator is generally about one to several ohms, so the above-mentioned electric detonator detonator needs to have a boost circuit and be able to provide an output voltage of the order of kilovolts. Therefore, the above-mentioned electric detonator detonator has certain danger in use. [000...
