A wireless transient trigger control method for explosive field

Abstract

A wireless transient triggering control method of a blast field comprises the following steps that 1) a modulation light source device and a photoelectric signal processing device are fixed near a blast source and a test node respectively; 2) a modulation signal wire is wound around an explosive column, a system is electrified, and the size of a laser spot in the test node is adjusted; 3) operation of the same frequency and the same phase is carried out on square waves generated by second and first controllers; 4) the amplification multiple of a secondary amplification circuit is adjusted, an output voltage V6 of a phase-locked amplification circuit is amplified as possible, a reference voltage Va of a comparison circuit is adjusted, so that the reference voltage Va of the comparison circuit is slightly lower than a negative-end input voltage V7, namely Va<V7, and an output voltage V8 is in low level; and 5) a photoelectric processing device is protected, and the second controller generates a triggering signal when a blast signal arrives. Thus, problems, in the triggering systems, that triggering response is slow, onsite wiring is inconvenient and influence of ambient light on the triggering system needs to be reduced are solved.

Description

technical field [0001] The invention relates to the field of control methods for testing explosion parameters in an external field, in particular to a wireless transient trigger control method for an explosion field. Background technique [0002] When various ammunition explodes, the detonation products of high temperature and high pressure destroy the projectile body and form a variety of damage elements, such as fireballs, fragments and shock waves. The test and evaluation of the damage effect is a necessary link in the development process of various explosives. However, the test environment of the explosion field is very harsh, and various types of explosives, weapon warhead power tests and rocket engine tests will be carried out in this environment. There are many parameters to be tested in the explosion field. There are many on-site test nodes, and there can be as many as dozens of measurement nodes for the same parameter. The trigger signals in various acquisition syst...
