Explosion initiating system and method

Abstract

The invention discloses an explosion initiating method. The explosion initiating method comprises the following steps: encoding explosion information including passwords of digital electronic detonators and delay time sent by an intelligent terminal and received by a power supply terminal, and transmitting the explosion information to the digital electronic detonators; performing switching of power after receiving information that the passwords are successfully unlocked and information that detonators wait for explosion initiation returned by all the digital electronic detonators, switching operation voltage into explosion voltage, controlling bus to charge capacitors in the detonators through data and sending information that a system waits for explosion initiation to the intelligent terminal; transmitting explosion initiation commands to the detonators after receiving the explosion initiation commands sent by the intelligent terminal according to the information that the system waits for explosion initiation, and enabling the detonators to perform explosion initiation according to the self-configured delay time. The invention also discloses an explosion initiating system. The explosion initiating system can be simplified; the explosion cost is reduced.

Description

technical field [0001] The invention relates to the technical field of blasting, in particular to a blasting system and method. Background technique [0002] The existing digital electronic detonator detonation system generally uses a detonator to connect multiple programmers, and then multiple programmers are connected to several electronic detonators to realize the detonation system with password detection and delay functions. [0003] First, carry out the blasting design for the blasting project and the site, design the number, position and delay time of the detonators of the entire blasting site, and input the blasting information into the detonator; the detonator decomposes the design content, and then downloads it to multiple programmers; each programming The detonator charges, tests, and programs each digital electronic detonator in its own control section, and all digital electronic detonators form a blasting network; then the detonator conducts system online testing...

Problems solved by technology

[0005] However, because this type of system uses a multi-level relay structure, in order to realize data transmission and detonation power supply, multiple programmers are required to cooperate with the detonator, and then the programmer is connected to the detonator, which makes the preparation for the blasting operation very complicated and time-consuming; And because of its special structure, many wires are needed to complete the system connection, which brings a lot of wire consumption to the blasting operation; although the digital electronic detonator detonation system in the existing technology has a delay function, most of them use a 555 timing circuit for timing, which cannot provide accurate timing. Delay, unable to meet the requirements of micro-difference blasting operations; in addition, the cost of digital electronic detonators in the prior art is relatively high

Therefore, this type of system has the disadvantages of a large number of equipment, complex operation, high blasting cost, and low delay accuracy.
