Fireworks air caption positioning method and device

Abstract

The fireworks airborne captions direction detection method and the equipment, it has a launch board, is vertical on the launch board to launches the pan even cloth to have certain decides as the hole or the set lever, delimits according to the letter writing either the design pen on the launch board on the index hole or the set lever the corresponding establishment fireworks also guaranteed each fireworks launcher tube diameter equal, the launch dose is same, simultaneously lights the fireworks explosive propellant, causes the fireworks simultaneously to lift off to identically highly explodes, in airborne forms one and the launch board plane vertical color flame writing or the design. The invention technique simple, use convenient, the modelling is reliable, but effectively improves the fireworks to set off watches the effect, is suitable for to take the company celebration, time the jubilation holiday sets off watches the fireworks.

Description

technical field [0001] The invention belongs to the fireworks manufacturing technology, in particular to a method and device for positioning subtitles in the sky of fireworks. Background technique [0002] Firework bombs are a kind of fireworks product developed in recent years, because they have a combination of sound, light and color effects when they are set off. Therefore, it has become a kind of fireworks product that people like very much. At present, there are many varieties of fireworks shells on the market, which not only have the effect of sound, light, and color combination, but can even form some simple patterns in the air; adding a lot of color to the night sky for people to celebrate festivals. But because existing fireworks shell is that prefabricated simple pattern is installed in a shell shell, promptly forms certain pattern by colored effect in the air after fireworks shell blasts into the air. Since the fireworks shells will rotate as a whole after they ...

AI Technical Summary

Problems solved by technology

Since the fireworks shells will rotate as a whole after they are lifted into the air, when they explode at a high altitude, the patterns produced cannot be positioned, which greatly reduces the viewing effect on the ground; at the same time, the height of each fireworks shell is not easy to determine when it is launched, so , the pattern coherence produced by the fireworks bomb after the high-altitude explosion is not good, which affects the overall viewing effect
