Abstract

The invention provides a communication protocol analysis method and system based on field descriptions. The method comprises: decomposing a communication protocol data frame into a series of field descriptions; on the basis of the field descriptions, analyzing each piece of byte data of an input communication message from front to back according to the field descriptions, wherein anayzling each piece of field data comprises the following steps that firstly, calculating an existence condition judgment formula; acquiring specific attribute parameters of a referenced field according to referencedefinition attributes of the field descriptions; initializing a repetition frequency counter of the current field as a repetition frequency value of the field; determining the data type of the field,and if the data type of the field is a field block type, executing analysis of each sub-field by adopting a nesting mode; if the type is not the field block type, acquiring data in the communication message according to the data length of the field; calculating a formula of a protocol identification judgment condition, and if a result is wrong, outputting an analysis error prompt; if the result iscorrect, executing the next step; and outputting a character string analysis result of the current field.

Description

technical field [0001] The invention relates to the technical field of digital communication, in particular to a communication protocol analysis method and system based on field description. Background technique [0002] A large number of different industrial sites have defined and adopted a variety of communication protocol standards in order to meet the needs of data collection and communication. Implementing these protocols in devices and equipment requires a significant programming effort. Especially when it is implemented based on programming languages, the development and debugging based on programming languages ​​such as C and Java are complicated and the workload is heavy. When the protocol is modified and upgraded, it is necessary to read and view the code for further programming and debugging tests. The Chinese invention patent "A Configurable Communication Protocol Identification and Analysis Processing System" (patent number: 201410012234.8) proposes a configur...
