中文摘要:

      烟花在发射到最高点爆炸时产生较强的声光信号，在地面适当位置安放声音传感器与光传感器采集声信号和光信号，由于传播速度不同且相差较大，声和光信号传播到传播到地面传感器有一定的时间差。基于烟花的声光特性，传感器输出的信号经电压比较电路后输入AT89S52单片机，AT89S52单片机对信号处理后测出时间差，用声音在空气中的速度乘以时间差可计算出烟花爆炸的高度。

英文摘要:

      Fireworks at the launch,will have a sound and light signals,using the characteristics of sound and light fireworks,the measurement of the height of the fireworks can be completed.Fireworks at the highest point of the explosion produces a strong sound and light signals,as the speed of sound and light being different and varied widely,when sound and light signals are transmitted to the sensors on the ground,there is a certain time difference.Light sensors and sound sensors are placed properly on the ground,used to capture the light and sound signals.AT89S52 MCU processes the signals collected by sensors,and measures the time difference,Fireworks explosion height can be calculated using the time difference multiplied by the speed of sound.
