摘　　要：标准莫尔斯码中,码间隔、字间隔、词间隔三种信号时间长度的比为1∶3∶5,而手工拍发的莫尔斯码各信号间的比例随机性较强,自动译码准确度不高。针对这一问题,研究了人工拍发莫尔斯码信号类别的识别算法,描述了该算法的思想及其程序实现。算法的关键是根据码速的实时变化,动态计算三种间隔信号时间长度的界定值。用C语言进行了PIC单片机的软件编程,给出了识别算法程序设计流程图及分析说明。In the standard Morse code, the proportion for the code-gap, character-gap and word-gap is 1 ： 3 ： 5, however, the proportion of the Morse handcraft code is around and random, which may decrease the precision of auto-coding. The signal sort recognition algorithm was studied aimed at the Morse code beaten by handcraft,and the design and the application program for this means were described in detail. The core of the algorithm is calculating the threshold values of the 3 kinds of gap signals dynamically, according to the real-time code-speed. C language for PIC single-chip was used for programming, and the main design flow chart and the analysis of the sort distinguish algorithm were presented.
