Method for synchronously triggering large-equivalent warhead static explosion experiment multi-parameter testing devices

Abstract

The invention provides a method for synchronously triggering large-equivalent warhead static explosion experiment multi-parameter testing devices. A center management system broadcasts trigger output signals through a wireless transmission system according to received trigger input signals; data acquisition devices distributed on an explosion site receive the trigger output signals and start to collect experiment testing data at the same time; a GPS module conducts time service on the data acquisition devices and records the triggering zero time of the data acquisition devices starting to collect the experiment testing data; a remote trigger monitoring meter monitors the trigger states of the data acquisition devices in real time through the wireless transmission system and conducts time-synchronization data processing on the collected experiment testing data. By adopting the method, multi-parameter testing devices which are distributed in a wide-range and long-distance mode can be effectively, wirelessly and synchronously triggered, and therefore the purpose of accurately estimating the power performance of large-equivalent arms and ammunitions is achieved.

Description

technical field [0001] The invention belongs to the technical field of explosion damage test, in particular to a wireless synchronous triggering method for multi-test equipment in a range explosion test. Background technique [0002] In recent years, the successful tests of the "Mother of Bombs" of the United States and the "Father of Bombs" of the Russian Army have demonstrated the deterrence of giant bombs to the world. The equivalent has reached the ton level or even higher, and the damage capability has been continuously improved. In the process of testing the power performance parameters of large-equivalent warheads, more and more test parameters are involved, such as fragment distribution, fragment velocity, shock wave, seismic wave, harmful gas concentration and other parameters that need to be tested at the same time; the test involves a large area and requires There are many layout points, and various test equipment are often arranged within a 360° range centered o...

Problems solved by technology

However, this traditional wired test has many problems in the large-yield warhead explosion test. The lead wire required by the wired trigger method is too long, reaching several kilometers, and the workload is huge; it is also easy to mix in interference electrical signals, which is easy False triggering, the protection of the triggering line of the remote device is not good, it is easy to disconnect before the detonation, causing the device to trigger in advance; in addition, the current test trigger system is only for single parameter test equipment, multi-parameter test equipment has multiple trigger sources, no one Unified trigger standard, unable to achieve synchronization

Therefore, the above-mentioned test triggering system has disadvantages such as long lead wires, heavy wiring workload, easy false triggering and early triggering, asynchronous triggering of multi-parameter test equipment, and a single triggering method.
