Design of beacon light switch based on spatial diversity laser communication

为了解决空间分集激光通信中信标光同步快速切换的问题,提出一种使用FPGA实现阵列信标光同步转换设计,解决了基于分集激光通信中多路信标光同步快速切换的问题。在此使用卡诺图编程方式,生成电机驱动时序,通过原理图编程方式设计多路粗精信标切换电路。实验结果表明,该方法实现了分集激光通信中多光路的协同工作,并有效地简化了传统信标光切换复杂的系统结构。

A new FPGA-based design of array beacon light synchronism switching is proposed to solve the problem of the multiplexing beacon light synchronism fast switching in spatial diversity laser communication.Karnaugh map programming method was used to generate the time sequence for driving four motors.The multiplexing rough and fine beacon light switching circuit was designed by means of the schematic diagram programming method.The experiment results show that the cooperative work of multiple light paths can be achieved in the diversity laser communication with the method.It simplified the complex structure of the traditional beacon light switch system.
