摘 要: 通过研究运动体的信号采集及信号传输的光通信互联模型,分析了瞬态光传输窗口的可行性.利用中断嵌套在系统软件中实现了周期性采样与瞬态数据传输.设计出基于电池驱动低功耗微处理器的运动体信号采集与瞬态无线光传输系统.该系统能在最高速率为25 m/s的周期运动机体上实现以0.7 ks/s的采样速率采样,1 Mb/s的传输速率瞬时传输数据. By studing signal acquisition of moving objects and optical interconnection model used in signal transmission, feasibility analysis of the optical transmission window is given, Using interrupt nesting in the system software, the periodic sampling and transient data transmission are fulfilled. The signal acquisition and transient wireless optical transmission system based on battery-driven low-power microprocessor is designed. The system can work on a cyclical movement object with the highest rate 25 m/s. The system's sampling rate can achieve 0.7 ks/s and the rate of instantaneous transmission can reach 1 Mb/s.
