Abstract

The invention relates to the technical field of radio, and discloses a Morse code recognition method, device and equipment based on a newspaper machine and a storage medium, which are used for improving the Morse code recognition efficiency. The method comprises the following steps: receiving a Morse code message, and judging according to a preset judgment threshold; wherein the level is a high level when greater than or equal to the judgment threshold and is a low level when less than the judgment threshold; carrying out edge capture to obtain duration time of a high level and duration time of a low level; calculating and adjusting a reference interval according to a preset rule, and determining a point code, a scratching code, a character interval and a word interval of the Morse code message in a current period of time according to the reference interval; separating character boundaries according to the dot codes, the scribing codes, the character intervals and the word intervals; and querying and obtaining corresponding characters in a preset Morse code comparison table according to the dot-row combination of the Morse message, and determining an identification result of the Morse message according to the characters and character boundaries.

Description

technical field [0001] The invention relates to the technical field of radio communication, in particular to a method, device, equipment and storage medium for identifying a Morse code based on a telegram machine. Background technique [0002] The Morse signal is similar to the ASK signal. It is a signal that is on and off. When the telegraph is pressed, it sends a single frequency signal. When the telegraph is released, it does not send a signal. Different letters and numbers are sent through different sending sequences. and punctuation marks. For variable-speed Morse code recognition, it is necessary to continuously update and adjust the reference interval according to the received Morse code data, so that the dot code, stroke code, word interval and word interval in a received Morse signal can be judged, and obtained by query recognition corresponding characters. However, the calculation and update of the reference interval are relatively complicated at present, and the...
