Problems solved by technology

However, the existing general parsing algorithms can only do simple one-to-one text conversion, that is, a binary value can only correspond to one text field; there are also general parsing algorithms based on fixed protocols, but it is necessary to limit the length of each data block and order
Existing general-purpose parsing algorithms are difficult to meet complex log parsing requirements, and cannot be applied to parsing occasions of various binary files

Embodiment 1

[0042] Embodiment 1 provides a method for parsing a binary file, which aims to display the relationship between binary members by establishing a tree structure of the structure. When parsing a binary file, a recursive algorithm is used to obtain the parsed text. In this way, it can adapt to binary membership relationships of various depths and binary structures of various lengths without repeated programming.

[0043] A recursive function refers to a function that calls the function itself. The definition of a recursive function is as follows: For a certain function f(x), its domain is the set A, then if for a certain value X0 in the set A, its function The value f(x0) is determined by f(f(x0)), then f(x) is called a recursive function. The recursive function will stop the recursive call when the termination condition is reached. The termination condition is usually that there is no element to call. The recursive function will return the linked list after the recursive call en...

Abstract

The invention discloses a binary file analysis method, which relates to the technical field of embedded software development. The invention is used for solving the problem of complicated binary valueconversion of the existing equipment, and comprises the following steps of: obtaining an analysis rule description file, and calling a recursive function to construct a structural body tree structureaccording to the analysis rule description file; receiving a binary file, and converting the binary file into a plurality of binary structure bodies; and sequentially recursively calling the structurebody tree structure through the plurality of binary structure bodies to obtain an analysis text of the binary file. The invention further discloses a binary file analysis device, electronic equipmentand a computer storage medium. According to the method, a tree structure is constructed through a recursive calling method, and then the binary file is analyzed by taking the tree structure as an analysis rule of a recursive function.

Description

technical field [0001] The invention relates to the technical field of embedded software development, in particular to a binary file parsing method, device, equipment and medium. Background technique [0002] Status information and operation logs of embedded products are commonly used data in the daily use and maintenance of equipment. This type of data has the characteristics of huge data volume and high storage frequency. Due to the limited storage resources and low computing power of embedded devices, it is difficult to read and write a large amount of text data at high frequency. Therefore, the current common practice is to store the status information and operation logs of products in files in the form of binary structures. , and convert it into a readable text file through specific parsing software when necessary. [0003] At present, there are many types of embedded products, and the binary meanings stored in different embedded products are different, requiring diffe...
