Pyrotechnic ignition device using supercapacitor module

Abstract

The invention relates to an initiating-explosive-device igniter with a super-capacitor module. The initiating-explosive-device igniter comprises an input module, a power module, a charging detonating module and a master control module, wherein the input module, the power module, the charging detonating module and the master control module are sequentially connected. In order to reliably achieve ignition of an initiating explosive device, the design scheme of a high-reliability ignition execution-grade circuit is adopted for a system. The initiating-explosive-device igniter with the super-capacitor module can meet the initiating-explosive-device detonating requirement in the large-current-requiring discharging environment, the applicable voltage range is wide, the applicable temperature range is wide, and the defect that a traditional initiating-explosive-device detonator is prone to failure under the low temperature condition is overcome; the size and the mass of a traditional initiating explosive device are greatly reduced through the circuit and the structure of the initiating-explosive-device igniter with the super-capacitor module, carrying is convenient, safety is good, battery pollution is avoided, the service life is long, maintenance is convenient, and maintenance cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of pyrotechnics, in particular to an ignition device for pyrotechnics using a supercapacitor module, which realizes the detonation function by charging and discharging the supercapacitor module. Background technique [0002] Initiating explosive devices are a general term for disposable components and devices that contain gunpowder or explosives and burn or explode after being stimulated by the outside to ignite gunpowder, detonate explosives or perform mechanical work. Pyrotechnics are important action devices and are widely used in civil and military fields, especially in the aerospace field. [0003] In the prior art, the ignition device of pyrotechnic products generally adopts an electric detonator, and the activation of the electric detonator is determined by the ignition current and ignition power, that is, the electric energy is converted into heat energy through the bridge wire with a certain resista...

AI Technical Summary

Problems solved by technology

It can be seen that the use of electric detonators requires a large ignition current and instantaneous high power to achieve normal detonation. In order to realize normal detonation, electric detonators can only use large-capacity batteries to directly discharge to realize the activation of electric detonators. Using large-capacity batteries to discharge directly will increase the volume and quality of pyrotechnics, which is difficult to meet in some environments that have strict requirements on quality and volume.

In addition, large-capacity batteries need to be replaced frequently, resulting in higher maintenance costs and polluting the environment
