本文提供了一种用于水下声遥控的多声频“串序”编码信号与控制逻辑。 为了抵御宽带噪声源对这种信号的干扰,文中给出了两种译码逻辑与控制系统,其原理是在接收端鉴定每一个声频的出现和持续时间,或者在接收机的译码电路中插入一定数量的“寂静时间段”来鉴定。 采用本系统可大大提高工作的可靠性。 This article provides a multi-audio “string order” coded signal and control logic for underwater acoustic remote control. In order to resist the interference of the broadband noise source to such signals, two decoding logic and control systems are given in this paper. The principle is to identify the appearance and duration of each audio at the receiving end, or in the decoding circuit of the receiver Insert a number of “silent periods” to identify. The system can greatly improve the reliability of the work.
