| 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...

| Abstract: | 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,us... |
