Automatic generation system of C language code on the basis of data configuration in trackside control unit

Abstract

The invention discloses an automatic generation system of a C language code on the basis of data configuration in a trackside control unit. The system comprises a database analysis module, a data structure module, an interlocking rule library module, a logic tree module and a C language generation module, wherein the data structure module defines a data structure required for interlocking expression and logic operation; the interlocking rule library module defines an operation rule based on an interlocking specification; the database analysis module reads interlocking data and configuration data and is combined with the data structure module and the interlocking rule library module to express interlocking data as a complex logic expression; the logic tree module analyzes the complex logic expression into a basic logic expression; and the C language generation module takes the list of the basic logic expression as input and is combined with the data structure module and the interlocking rule library module, and a final C language code file is generated according to the configuration data, the interlocking data and existing source code information. The analysis and the code compiling of the complex logic expression on the basis of the data configuration can be accurately processed.

Description

technical field [0001] The present invention relates to software code generation technology. Background technique [0002] At present, the interlocking software of the trackside control unit in the CBTC (Communication Based Train Control) system of the subway needs to deal with complex signal scenarios based on complex logic expressions. Software engineers need to read data tables and manually Analyze complex logic expressions, and then write codes based on the analyzed signal logic. In this process, on the one hand, complex logic expressions have complex logic, large amount of data, and high degree of data coupling. Manual analysis is prone to errors. On the other hand, due to the high similarity of basic data types, expressions with similar logic have similar parsing algorithms, but due to the different data content, a large number of repetitive manual parsing processes and code writing and debugging processes have been caused. How to efficiently and accurately process t...
