本文介绍了实时遥控群控系统的特点,并从指令码结构和伪随机码结构的设计着手,提出了一种起始相位可随机浮动的系统瞬间同步方法.这种方法的特点是电路结构简单,不存在传统同步方法中的同步跟踪时间和同步保持时间,保证了被控对象反应迅速、动作准确,达到了实时遥控的要求. This paper introduces the characteristics of real-time remote control group control system, and from the design of the code structure and pseudo-random code structure, an instantaneous synchronization method of system with initial phase can be randomly floated, which is characterized by simple circuit structure , There is no synchronization tracking time and synchronization holding time in the traditional synchronization method to ensure that the controlled object responds promptly and moves accurately and meets the requirements of real-time remote control.
