Problems solved by technology

The main disadvantage of this device and method is: only the size of the energized current of the pyrotechnics control system can be tested, and the energized sequence (that is, the circuit on and off time and its sequence) cannot be tested
This manual detection scheme has the following main disadvantages: 1) During the test process, a tester usually has to complete a variety of actions, and in addition to the large number of signal lights and the fleeting intervals between flashes, it is impossible to complete real-time data processing and can only be interpreted afterwards; 2) The flashing time and interval of the signal lights are very short, and the testers need to slow down or even playback the video files frame by frame, which takes a long time and the interpretation efficiency is low; 3) The status monitoring of the signal lights depends entirely on the naked eye judgment of the testers, This not only easily causes personnel fatigue, but also easily causes missed judgments and misjudgments; 4) multiple equivalent devices are monitored by multiple cameras respectively, and correspond to multiple video channels on the video recorder. The clock is seriously inconsistent (several seconds to tens of seconds), resulting in the inability to uniformly interpret the entire timing sequence, and the timing detection accuracy is low

Embodiment

[0082] The non-contact pyrotechnic product control timing detection device for directional demolition blasting is installed at the demolition site of buildings, and is used to detect whether the power-on control timing of the demolition system of directional demolition buildings is correct. Due to the very precise control of the pyrotechnics, the explosion sequence of each detonation point must correspond to the design sequence, so the current excitation method is used to control its detonation. Due to the one-time nature of the ignition and detonation work, it is impossible to test the entire detonation system with genuine pyrotechnic products. Therefore, after the on-site installation of the detonation system is completed, an equivalent device is used instead of the genuine product to connect to the detonation system. A signal light on the equivalent device is correspondingly connected to a detonation point in the detonation system, and multiple detonation points in adjacent ...
