智能化列车引擎，以避免事故的发生

this is sleep and time function, you can have a look. it is programming by c language, the gold of this program is achieve   1.how to use time functions to measure time 2. to understand program execution in a multi-task environment 3. to understand the concept of time drift

基于8051的FFT计算代码，经过修改可实现任意长度的FFT运算。 可用于估计采样信号频谱。 该代码已经经过测试。

通过提升机械传动轴的转角脉冲计数,将计数值与预置值作对比,即可确定驱动电机的启停升降,达到平层就位的目的.以AT89C51为CPU,在中断处理程序中对外来脉冲计数.-Through enhancing the mechanical shaft angle of the pulse count, will be of value for comparison with preset values, you can determine the start and stop the motor-driven movements, to achieve the purpose of flat layers in place. To AT89C51 for the CPU, interrupt handling procedures in foreign pulse counting.
