Automatic large fireworks ignition system

Abstract

The invention discloses an automatic large fireworks ignition system which comprises a main control computer and a plurality of ignition box groups, wherein the main control computer is connected with the ignition box groups through a wireless module. The automatic large fireworks ignition system is characterized in that ignition heads of the ignition box groups are connected with an ignition output end and a detection output end of an ignition circuit, the ignition circuit is controlled by a triode switch, the ignition output end outputs in a unidirectional conducting manner through a diode, and the detection output end outputs after unidirectional conduction of the diode and current-limiting of a current-limiting resistor. Double chips are used for control, a timer delays electrification, and double relay switches are used for control. Delay is effectively prevented, the whole system eliminates the probability of accidental ignition in detection in the operating process of setting off fireworks, and personnel security is ensured.

Description

technical field [0001] The invention relates to a large-scale automatic ignition system for fireworks, specifically, it has a very high safety factor in the detection and ignition of the discharge, which ensures effective detection in the entire discharge process and stops the discharge control in some dangerous areas, thereby ensuring safety. The premise is to greatly reduce the impact on the discharge effect. Background technique [0002] Currently, there are two types of fireworks display control technology, one is the use of professional audio equipment that supports time code signal output, and the other is the self-developed ignition system controlled by a single-chip microcomputer, which runs related control software through the computer and plays The music side sends the control command to the remote device through the communication interface to realize the controlled discharge of fireworks. [0003] In summary, the above two methods lack an effective risk control m...

Problems solved by technology

[0003] In summary, the above two methods lack an effective risk control mechanism in the discharge detection stage, and the probability of misplaced points during the detection stage is relatively high. Once a misplaced point of detection occurs, it will cause great danger to the construction personnel on site; in addition In the process of actual discharge, if you encounter a dangerous situation, you can only stop all the discharge or continue to discharge without dealing with the crisis, which will greatly sacrifice the effect and personnel safety.
