example 1

[0078] Example 1. Confidentiality and simplicity of data transmission

[0079] Take the commonly used GBK encoding for the conversion of the 7-character field of "I donate oil for the motherland" as an example, as shown in Table 2:

[0080] Table 2 GBK encoding example

[0081]

[0082]

[0083] In the large base code, the decimal 346153123902322394217053359017831 in the large base system (such as the billion base system) is only 346153 nanoseconds, 123902322 nanoseconds, 39421705 nanoseconds and 359017831 nanoseconds. Four pulses of 3 carry, 2 carry and 1 carry. From the point of view of simplicity, the four energy pulses can be completed in an instant and do not occupy traffic; from the point of view of confidentiality, most of them cannot be deciphered by anyone who intercepts them.

example 2

[0084] Example 2. Simulated data transmission rate and byte count

[0085] In order to compare with the traditional method, a set of 64 columns × 20 rows of hexadecimal random numbers is simulated, see Figure 5 shown.

[0086] It adopts a 10-channel, 64-bit in-line transmission method using large base conversion, and the data body is divided into 2 blocks for processing. In a single line in 1024 base (2^10, easy to compare and convert), see the carry analog comparison diagram Image 6 shown.

[0087] Depend on Image 6 It can be seen that the 64-bit random number in the same row only needs 26-bit positions in the 1024 base to express. Therefore, the comparison between the two expressions is shown in Table 3:

[0088] Table 3 Comparison between the traditional transmission mode and the hourly transmission mode of the present invention

[0089]

[0090] From the above, it can be seen that the advantages of using time as the scale system in terms of transmission rate, r...

Abstract

The invention discloses a data transmission method, which comprises the following steps of: converting information to be transmitted into a time system number, and representing the information to be transmitted by the time system number through a time numerical value; determining a time period for sending a pulse corresponding to the to-be-transmitted information according to the time system number and the time step length; and sending pulses corresponding to the information to be transmitted at intervals according to the time period. The invention also discloses a data transmission method. The method comprises the following steps: receiving pulses corresponding to transmission information at intervals; determining a time period of receiving pulses corresponding to the transmission information at intervals; according to the time period and the time step length, determining a time system number corresponding to the transmission information, the time system number representing the information to be transmitted with a time value; and restoring the transmission information according to the time system number. The invention further discloses a data transmission device. According to theinvention, data transmission with concise coding, difficult cracking of transmission encryption and ultra-low flow can be realized.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a data transmission method and device. Background technique [0002] This section is intended to provide a background or context to embodiments of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] Existing data transmission usually uses binary, octal, hexadecimal or decimal and other decimal systems to encode data to achieve transposition and transmission, such as the current international ASCII code, Unicode, Chinese character set encoding table, etc., the current The data transfer mode suffers from the following problems: [0004] A: The encoding is cumbersome due to the small base, for example, the hexadecimal code of Hanzi "seven" is ****. The limitation of the base size makes it impossible for humans to create and use a large number of single characters, such as 1, 2, A, ...
