This paper is designed to simulate fireworks device to achieve the type of sound and effects by the electronic components ,some dust pollution and the risk of explosion hazard safety, environment, peoples environmental protection has brought a relaxed atmosphere. Use STC89C52RC smallest single-chip system for each part of the electronic fireworks, real time control.Use buzzer to replace the traditional sound effect .And add some songs make music richer effect.Use LED dot matrix instead of traditional fireworks show that can show more font and flower.The key switch to solve the drawbacks of tro=aditional fireworks device control.The The new circuit structure, element small, easy to debug, for homemade. It can also be used for small businesses open design engineering and technical personnel reference. The device can be used for family, friends, celebration, party, childrens toys and some interesting places Keywords: Small electronic acousto-optic ceremony Flower ；Festival fireworks ；nvironmental protection 目 录 1 引言 1 1.1 课题研究的背景及意义 1 1.2 课题研究的现状及发展趋势 1 1.3 课题研究的内容 1 2 总体方案设计 2 2.1 设计要求 2 2.2 方案选择 2 2.2.1 单片机芯片的方案 2 2.2.2 显示模块的方案 2 2.2.3 发声模块的方案 2 2.2.4 按键模块的方案 2 3 系统硬件设计 4 3.1 单片机控制模块 4 3.1.1 STC8
