Problems solved by technology

[0010] The Morse newspaper was originally sent by a code-printing telegraph, which is a completely manual telegraph, and the sending of messages is completely controlled by humans. Before using the code-printing telegraph to send Morse, it took a lot of time to Training operators is time-consuming, labor-intensive and expensive. Due to the limitations of the human body, the manual sending speed of Morse newspapers is limited, resulting in low work efficiency, and there will be some unpredictable errors, which makes Morse The communication quality of the Morse newspaper declined; later, the invention of the printing telegraph greatly improved the communication quality of the Morse newspaper. To meet the needs of modern communication, the maximum rate of this transmission method is only 80 yards per minute, which is four or five times faster than the code printing telegraph, but it is far from meeting the demand
Disadvantages of the Morse newspaper communication method: low efficiency, time-consuming, labor-intensive and money-consuming, communication quality cannot be guaranteed, and communication speed cannot meet the requirements

Embodiment 1

[0037]In the present invention, the transmission content can be randomly input on the software interface, or it can be a randomly generated scheme, and the code rate is randomly set without limitation, but in view of the hearing ability of the human ear, the code rate is generally not greater than 300 yards / minute . According to the regulations of Morse code code symbols, first judge whether the input message content is reasonable, code symbols are usually divided into: English letter code symbols (referred to as "word code"), digital code symbols (referred to as "digital"), mixed Code is the electric code symbol that word code and digital long code are mixed together. If it meets the requirements of the code symbol, then call the Morse newspaper database, otherwise, do not do any processing, and exit the workflow.

[0038] Establish the Morse newspaper database, according to the English letter A~Z, a~z code symbol table, the English letter code symbol table, the digital 0~9 ...

Embodiment 2

[0049] On the basis of the above examples, if figure 2 As shown, the present invention relates to a variable and controllable code rate Morse newspaper software programming method, wherein, comprising the following steps:

[0050] Step 101: According to the regulations of the Morse code code symbol, judge whether the input message content is reasonable, if yes, call the Morse newspaper database; otherwise, exit;

[0051] Step 102: Calculate the number of "points" converted into the code symbol corresponding to each character in the Morse newspaper database, and save it;

[0052] Step 103: Calculate the number of "dots" corresponding to the sent content, call the function interface, the sent content is composed of a series of characters, save it as a string of CString type, and judge from the first character to the last character cyclically, Call the Morse newspaper database, and save the total number of "dots" corresponding to the code symbols of the characters in the string...

Abstract

The invention provides a software programming method of Morse telegraph at variable controllable code rate. The method include the steps of 101, judging whether input message content is reasonable or not; 102, calculating the number of 'points' converted from a code symbol corresponding to each character in a Morse telegraph database; 103, calculating the number of 'points' corresponding to content to be transmitted; 104, calculating the number of spaces and the number of non-space characters in a message, and setting a 'point' time; 105, calculating the time of transmitting one 'point' at the set code rate; 106, establishing a Morse telegraph transmission database till the code symbol corresponding to the last character is transmitted. The method according to the scheme has the advantages that labor is greatly saved, material and property resources are saved, work efficiency and communication efficiency are improved, message content and code rate are controllable, and Morse telegraph communication is more flexible.

Description

technical field [0001] The invention belongs to the technical field of software programming, and in particular relates to a variable and controllable code rate Morse newspaper software programming method. Background technique [0002] The Morse newspaper, commonly known as the telegraph, is widely used in the military field. It is a code symbol consisting of dots (.) and dashes (-). At present, the transmission of Morse newspapers mainly relies on code-printing telegraphs and printing telegraphs. Code-printing telegraphs, namely Morse telegraphs, are the earliest tools used to send messages. When sending messages, operators need to Combination of electric code Press or release the electric key to control the circuit, print dots and strokes on the paper, so as to realize the transmission of Morse newspapers. For example, when sending Chinese telegrams, it is necessary to first translate Chinese characters into numbers, and then convert the numbers into The electric code is a...
