Accurate rocket two-stage electronic delay ignition device

Abstract

The invention provides an accurate rocket two-stage electronic delay ignition device. The accurate rocket two-stage electronic delay ignition device comprises a power supply module, an acceleration detection module, an AD acquisition module, a main control module I, a safety ignition circuit I, a super-capacitor module, a main control module II and a safety ignition circuit II, wherein the power supply module, the acceleration detection module, the AD acquisition module, the main control module I and the safety ignition circuit I form a first-stage ignition device; the super-capacitor module,the main control module II and the safety ignition circuit II form a second-stage ignition device; and the power supply module is used for supplying power to the acceleration detection module, the ADacquisition module and the main control module I, supplying power to the main control module II of the second-stage ignition device before the two stages of circuits are separated, and charging the super-capacitor module of the second-stage ignition device. The delay ignition time is controlled through the two stages of ignition devices, dependence on the combustion performance of initiating explosive devices is avoided, and the accuracy is high.

Description

technical field [0001] The invention relates to the technical field of rocket ignition devices, in particular to an accurate two-stage electronic delay ignition device for rockets. Background technique [0002] Rockets are widely used in civilian fields. When a civilian rocket is launched, it generally realizes the corresponding function by providing electric energy to detonate the pyrotechnic product in the rocket at a specified delay time point. The ignition delay time of traditional civilian rockets is related to the combustion performance of pyrotechnics inside the rocket body. The accuracy of the delay time depends on the process of pyrotechnics, and there are errors, which restrict the function expansion of civilian rockets. Contents of the invention [0003] In view of this, the present invention provides a precise rocket two-stage electronic delayed ignition device, which controls the delayed ignition time through the two-stage ignition device, does not depend on ...
