Problems solved by technology

CRC check is also called cyclic redundancy check. Although it has strong error detection ability and is easy to implement, it cannot detect two or more errors, and its polynomial generator is used for comparison of original numbers. For a long time, you can only check for errors, not correct them, and cannot locate them

Embodiment 1

[0121] A method for verifying information transmission, the steps of the method are as follows:

[0122] The S1 collection terminal collects data information to form a computing information body;

[0123]In this embodiment, 6 segments of data, each of which has 6 elements of data, are taken as an example to further describe the specific verification method. The collected data is expressed as follows:

[0124] F2 A0 00 00 00 CD 06 33 00 18 00 D8 07 00 00 FF 47 D3 08 82 00 3E 00D4 09 11 00 C2 07 27 71 26 02 02 01 42

[0125] Remove the function code at the head end and the check code at the end of the collected data information as follows:

[0126] A0 00 00 00 33 00 18 00 00 00 FF 47 82 00 3E 00 11 00 C2 07 26 02 0201

[0127] S2 processes and calculates the information body to form a matrix of order n*m;

[0128] Composing the above information into a 6*4 matrix is ​​expressed as follows:

[0129]

[0130] Set a row matrix for level-1 verification as follows:

Abstract

The invention relates to the technical field of information transmission, in particular to an information transmission verification method and system. The system firstly forms data information into acalculation information body; a plurality of n*m-order matrixes are formed; the n*m-order matrix and a preset line array are converted for multiple times to obtain a multi-level check code; the acquisition end sends the acquired data information and the multi-level check code to a receiving end; the receiving end also adopts a preset line array to carry out conversion for multiple times to obtaina corresponding multi-level check code; and the multi-level check code is compared with the multi-level check code of the acquisition end to find out error data. According to the information transmission verification method, deep mining analysis can be carried out on real-time data and historical data, the development and operation rules of all the data are mastered, planning of the data information is optimized, global control over the data information and optimal control over system resources are achieved, and the safety and reliability of the data information are improved.

Description

technical field [0001] The invention relates to the technical field of information transmission, in particular to an information transmission verification method and system. Background technique [0002] In the process of data transmission, it will be affected by various interferences, such as pulse interference, random noise interference and artificial interference, etc., which will cause data errors. In order to control the errors in the transmission process, the communication system must take effective measures to control the generation of errors. [0003] Commonly used error control methods allow each transmitted data unit to have redundant information sufficient to enable the receiving end to discover errors. This method cannot correct errors, but can detect data errors. This method is easy to implement and has a fast error detection speed. Errors are corrected by retransmission, so it is a very common error detection scheme. When there is a lot of data collected in r...
