Abstract

The invention discloses a safe and reliable igniter circuit for an initiating explosive device explosion test and a working method thereof. The purpose of how to ensure that an ignition circuit is ina safe state in both working and non-working states in the initiating explosive device explosion test is achieved. Control circuits controlling the on and off of the circuit are added separately in atraditional ignition circuit of an initiating explosive device explosion test circuit, and the action of starting the ignition is broken up into three steps of closing the ignition circuit, giving anignition signal and cutting off the ignition circuit to be carried out, and a light-emitting indicator is arranged to show the on and off of the ignition circuit, so that the ignition process is regulated from a safety point of view, the safety of the igniter circuit in use, recycling and storage is ensured, and a safe and practical operation method and technology is provided for field test operators.

Description

technical field [0001] The invention relates to an igniter circuit for explosion test of pyrotechnics, in particular to a safe and reliable igniter circuit for explosion test of pyrotechnics and its working method. Background technique [0002] After the design, production and assembly of new pyrotechnic products are completed, explosion tests are generally required. The explosion test is carried out through an igniter. The ignition circuit in the igniter receives an ignition start signal and outputs a Ignition current, ignites pyrotechnics, and makes it complete the explosion test; the existing igniter circuit has the following problems in use, recovery and storage: (1) During the ignition test, it cannot be accurately judged whether the ignition signal circuit is connected (2) When using the same igniter to test multiple pyrotechnics, there is a high risk of accidental explosion during the replacement of pyrotechnics; (3) The safety of the ignition circuit operation is uns...
