Long-distance multi-channel boosting detonation device

Abstract

The invention discloses a long-distance multi-channel boosting detonation device. The long-distance multi-channel boosting detonation device comprises a communication cable, a bus controller and a plurality of boosting detonation modules, wherein the bus controller and the boosting detonation modules are connected to the communication cable. The bus controller issues a deprotection instruction and a communication triggering instruction to the boosting initiation modules to control the boosting initiation modules to perform synchronous ignition or time-sharing ignition; each boosting detonation module comprises a communication and security circuit and a boosting ignition circuit; each communication and security circuit is triggered by the deprotection instruction to release an internal electric safety signal and output an energy signal required by the boosting ignition circuit; when each boosting ignition circuit receives the energy signal, the boosting ignition circuit boosts the energy signal so as to charge energy storage capacitor; And after a communication triggering instruction is received, the energy storage capacitor is controlled to discharge to an initiating explosive device. According to the invention, the bus controller sends the information instruction to the corresponding boosting initiation circuits to finish multi-path long-distance accurate ignition, so that the anti-interference capability between ignition channels and the comprehensive performance of an in-line ignition system are improved.

Description

technical field [0001] The invention belongs to the technical field of explosive detonation control, and more specifically relates to a long-distance multi-channel boosted detonation device. Background technique [0002] Pyrotechnics, also known as fire equipment, are widely used in military projects such as strategic missiles, nuclear weapons, and aerospace systems. As a miniaturized and sensitive explosive energy source, pyrotechnics are not only the "source" for weapons and explosive systems to complete their intended functions, but also the "root" for these systems to accidentally explode and cause personal casualties. Therefore, as a pyrotechnic product of explosive energy, the reliability and safety of its ignition circuit are very important. [0003] Due to the interference between different ignition paths and strong electromagnetic interference in the environment, the existing multi-channel pyrotechnic ignition circuit needs to adopt a complex electromagnetic shield...

AI Technical Summary

Problems solved by technology

[0003] Due to the interference between different ignition paths and strong electromagnetic interference in the environment, the existing multi-channel pyrotechnic ignition circuit needs to adopt a complex electromagnetic shielding design, which is costly and not reliable. Fully guaranteed; in addition, when only relying on capacitor charging and discharging to achieve ignition, the reliability and sensitivity are poor, which reduces the practicability of the existing ignition circuit
