High-precision wired setting and timing detonator and timing detonating method

Abstract

The invention discloses a high-precision wired setting and timing detonator and a timing detonating method. The detonator comprises a setter and a detonator body. The setter comprises a keying unit, a single-chip microcomputer I, a data transmitting unit, a setting opening I and a display unit connected with the single-chip microcomputer I, wherein the keying unit, the single-chip microcomputer I, the data transmitting unit and the setting opening I are sequentially connected. The detonator body comprises a setting opening II, a data transmitting unit, a single-chip microcomputer II, a security unit, a detonating unit, and a navigational satellite receiving unit connected with the single-chip microcomputer II, wherein the setting opening II, the data transmitting unit, the single-chip microcomputer II, the security unit and the detonating unit are sequentially connected. The setting opening I and the setting opening II are connected in a wired mode. The setter is used for setting the setting time and sending the setting time to the detonator body, after receiving the setting time, the detonator body feeds the setting time back to the setter and quits setting after confirmation, the detonator body delays according to the delay time calculated through the setting time and the received timing time, receives the timing time again before delaying is finished, and detonates according to the timing time, the high-precision timing detonation is achieved, and use is safe and reliable.

Description

technical field [0001] The invention relates to the field of fuzes, in particular to a high-precision wired fixed timing detonator. Background technique [0002] The traditional timing detonation has a clock and watch method. When using it, the watch must be adjusted to synchronize with the local time, then the detonation time is set, and the detonation is performed until the detonation time is reached. There are problems such as large error, large volume and low reliability. There is also an electronic delay detonation mode, the detonation time is determined by the opening time, the opening time is different, the detonation time is just different, and its delay time is fixed. There is also a wired electronic delay detonator that can be installed, and its delay time can be set, and the delay time is flexible. It is difficult for them to achieve precise timing detonation. Some detonators are stored and transported separately from the charge, and are combined during use wit...

AI Technical Summary

Problems solved by technology

They are difficult to achieve precise timing detonation

Some detonators are stored and transported separately from the charge, and are recombined when used, without isolation insurance; some detonators are equipped with setting insurance, which will be released after a certain period of time after the setting is completed; these methods are not safe
