Nonpolar double-wire communication digital electronic detonator capable of self-delaying and detonation method thereof

Abstract

A nonpolar double-wire communication digital electronic detonator capable of self-delaying, comprises a leg wire and a pipe body, wherein the pipe body comprises a pipe casing, and an ignition device, a detonator charging and tail plugging device, a control circuit and an ignition energy storage device, which are installed in the pipe casing. The control circuit comprises a power supply module, a communication module, a core control module and an ignition loop module, which are orderly electrically connected; input terminals A and B of the power supply module are connected to the leg wire, the ignition loop module is electrically connected with the ignition device and the ignition energy storage device; and a detonation method comprises: (1) detonator configuration, (2) networking, and (3) detonation operation. The nonpolar double-wire communication digital electronic detonator has a UID code and detonation authorization code verifying function, has advantages of controllable itself, high authority security, convenient self-delay, on-site laying, accuracy detonation control, good explosion effect, no need to distinguish polarities of the leg wire, convenient usage and low human error rate, and can obtain higher delay precision by using an internal clock module or an external clock module.

Description

technical field [0001] The invention relates to an explosive, in particular to a non-polar two-line communication digital electronic detonator capable of autonomous delay and its detonation method. Background technique [0002] The detonator itself is a dangerous product. If insufficient supervision leads to illegal flow into the society, it will pose a great threat to public safety. Most of the existing electric detonators are managed by marking the casing, and the detonators without marking are not allowed to leave the factory, be sold or used. Such a system regulates the production management of the detonator market, but it cannot prevent the illegal use of detonators. If criminals obtain detonators through illegal channels, they can easily use them for blasting. At this time, there is no restriction on the coding of the shell. force. [0003] Due to the above defects of the old-fashioned electric detonator, the digital electronic detonator and blasting system came into...
