Description
Technical Field
The invention belongs to the field of Morse code emission, and particularly relates to a Morse code emission method and a Morse code emission device.
Background
Morse code, also translated into Morse code, is a signal code that is on and off at any time, and expresses different English letters, numbers and punctuation marks by different arrangement sequences. It was invented in 1837, the inventor had controversy that the American person was either Samuir. Morse or Elfeld. Vill. Morse code is an early form of digitized communication, but unlike modern binary codes that use only zero and one states, its code includes five: dots, strokes, pauses between dots and strokes, short pauses between each character, medium pauses between each word, and long pauses between sentences.
Since the advent of radio and morse code, military communication has entered a new era, but radio communication is an open system, and the party can receive the message and at the same time the other party can "make a glance" so that the code that has been appeared in the course of war in history of mankind can be immediately combined with radio to obtain radio code.
The traditional morse code is a fixed single frequency; resulting in poor ability to resist interference with communications during automatic reception of morse code by a computer.

Example 1:
as shown in fig. 1, the present embodiment provides a morse code that is resistant to interference, and audio signal bands of a plurality of frequencies are inserted into a signal of the morse code, and the audio signal bands serve as identification codes for analysis by a receiving end. The band of audio signals inserted between an interval of the morse code signal codes is a single frequency. That is, at the same time, the signal is emitted with only one frequency, in fig. 1, F1 represents the frequency of morse code, and F2, F3, F (n-1), F n are the inserted audio signal bands. When the Morse code is transmitted, the codes of the Morse code have time pause, the pause forms the interval between the codes, and when the audio signal wave band is inserted, the mode of the control switch is used, when the codes are input, the audio signal wave generating circuit can be controlled by the switch circuit, the audio signal wave generating circuit is opened to generate a section of audio signal wave band in the pause time period of the Morse code input, and the audio signal wave generating circuit is closed by the switch circuit between the next Morse code input; thus, signal waves which do not cross and influence each other are realized.
The Morse code signal is identified in a specific audio signal wave band by inserting the audio signal wave bands with a plurality of frequencies into the Morse code signal, taking the audio signal wave bands as identification codes for a receiving end to analyze, receiving the Morse code signal with the audio signal wave bands with a plurality of frequencies at the receiving end and identifying according to the audio signal wave bands, so that the Morse code signal is identified in the specific audio signal wave band, and the anti-interference capability of the Morse code is improved; the problem that the traditional Morse code is a fixed single frequency, so that the ability of resisting interference communication in the receiving process of the Morse code is poor is solved.
In particular, the audio signal band may include long, medium, short, ultra-short and/or microwave. The audio signal wave band can select various waves to perform anti-interference processing on Morse code, and the method is suitable for realizing independent receiving among different codes in the same environment, and embodies the operability and practicability of the method. The audio signal band is inserted between intervals of the Morse code signal codes. Through inserting the audio signal wave band between the interval of morse code signal code, can avoid the influence to morse code signal code, the interference killing feature of realization morse code signal that again can be fine improves the practicality.
In specific implementation, the Morse code filters the inserted audio signal wave band by a filter during manual copying, and then obtains the frequency signal of the Morse code. Considering that the Morse telegraph also needs manual transcription in certain environments, the Morse telegraph can obtain the Morse telegraph code with single frequency after filtering the inserted audio signal wave band through the filter, thereby receiving the telegraph code through the manual transcription, realizing the anti-interference when using the computer to receive, and being compatible with the effect of the manual transcription.
In particular, by inserting a single frequency audio signal band between each Morse code signal code interval, the power of the device is prevented from being affected. The audio signals are inserted into intervals of the Morse code signal codes according to a preset sequence, and the receiving end analyzes the audio signals according to the preset sequence. Each interval of the Morse code signal codes is interleaved with a band of audio signals of one frequency.
Example 2
As another embodiment of embodiment 1, a plurality of audio signal bands of frequencies are inserted into the morse code signal, and the audio signal bands are used as identification codes for the receiving end to analyze. The audio bandwidth of the audio signal wave band is 20 Hz-20 KHz. For example, the emitted Morse code signal codes are 20Hz between the first intervals, 80Hz between the second intervals, and 160Hz between the third intervals, and then the audio signal bands of the three frequencies are cyclically inserted at the following intervals. Of course, the insertion is not limited to 3 frequencies, and more intermediate frequency audio signal bands may be inserted according to the requirement.
Example 3
The Morse code signal is inserted with a plurality of frequency audio signal wave bands, and the audio signal wave bands are used as identification codes for analysis of a receiving end. In particular, the audio signal band may include long, medium, short, ultra-short and/or microwave.

The audio signal band is inserted between intervals of the morse code signal codes. In particular, the band of audio signals inserted between an interval of the morse code signal codes is a single frequency. In specific implementation, the insertion is performed according to the preset number of intervals when the audio signal wave band is inserted.
When the audio signal wave band is inserted, the audio signal wave band can be inserted at each interval of Morse code signal codes, or the audio signal wave band can be inserted at certain intervals, and the corresponding decoding mode is adopted for analysis during decoding, so that different decoding modes are realized.
Example 4
The Morse code signal is inserted with a plurality of frequency audio signal wave bands, and the audio signal wave bands are used as identification codes for analysis of a receiving end. The audio signal band comprises long wave, medium wave, short wave, ultra-short wave and/or microwave. The audio signal band is inserted between intervals of the Morse code signal codes. Further, the preset number of intervals is the same number of intervals. Of course, the number of the preset intervals may be the same or different. In a specific implementation, for example, the morse code signal code that is transmitted sequentially transmits one high-frequency signal, two morse code codes, one intermediate-frequency signal, and two morse code codes from the first code; thus, it is equivalent to inserting one other signal every interval by one interval number; of course, the number of the inserted intervals and the frequency signal inserted each time can also be inserted according to a preset insertion algorithm, for example, a preset encryption algorithm is adopted; meanwhile, the same decryption algorithm is adopted at the computer identification end for identification, and Morse code anti-interference transmission is achieved.
