A large-scale initiation method of digital electronic detonator for engineering blasting

Abstract

The invention relates to the technical field of blasting engineering priming control and discloses a digital electronic detonator large-scale priming system for engineering blasting and a method thereof. A priming network main machine is sequentially connected with a plurality of priming network auxiliary machines in series through an RS-485 serial communication cable; and each priming network auxiliary machine is connected with a digital electronic detonator group. According to operation on the priming network main machine, fault detection, order control, information inquiry and display are performed to a whole priming network. According to an order of the priming network main machine, each priming network auxiliary machine performs +24 voltage-to-digital converter (VDC) power supplying and sends an order information code to the digital electronic detonator group connected. Corresponding power supply control action-charging and priming are performed and corresponding communication information is fed back. According to the digital electronic detonator large-scale priming system for the engineering blasting and the method thereof, visible operation of large-scale complex priming can be achieved, a priming safety factor is increased, dangerous operation is reduced, environmental pollution is reduced, and good economic and social benefits are achieved and the digital electronic detonator large-scale priming system for the engineering blasting and the method thereof are suitable for being used in a high-precision millisecond blasting occasion.

Description

technical field

[0001] The invention relates to the technical field of blasting engineering initiation control, in particular to a large-scale initiation system and method of a digital electronic detonator for engineering blasting, which are suitable for large-scale, high-precision differential blasting occasions. Background technique

[0002] Traditional large-scale blasting projects mainly rely on the electric detonator initiation system. The larger the blasting project, the more detonators are used; the higher the required detonation voltage, the lower the safety of on-site use. Moreover, the general electric detonator only needs an ordinary power supply to detonate, which is easy to be used by illegal blasters, which is not conducive to the safety supervision of the use of the detonator.

[0003] In addition, in large-scale blasting projects, due to the complex terrain on site, in order to achieve the best blasting effect, the blasting process is strictly controlled, an...
