Embodiment Construction

[0025] The technical solutions of the present invention will be further described below with reference to the accompanying drawings.

[0026] like figure 1 As shown, an automatic integration method of IO signals based on FADEC operating system includes the following steps:

[0027] (1) Use Eclipse CDT to parse out all the structure variables in the As_interface.h file, and store all the structure variables in the linked list A, each element in the linked list contains all the information of the corresponding structure variables;

[0028] (1.1) Use CDT to parse all the variables defined in the As_interface.h interface file (integer, floating-point, enumeration, etc.), including variables of basic data types, macro definitions, and user-defined structure variables, such as figure 2 as shown in a;

[0029] (1.2) Extract the structure variable defined by the user, and store the structure variable information to form a linked list A.

[0030] (2) Extract the effective informati...

Abstract

The invention discloses an automatic IO signal integration method based on an FADEC operating system, and the method comprises the following steps: analyzing all structural body variables in an Ainterface.h file by using Eclipse CDT, and storing all structural body variables in a linked list A; extracting effective information of each element in the linked list, and storing the information in a new linked list B; according to structure variable names A0-An-1 which are formulated in advance and used for signal interaction between the AS and the OS, the chain table B is converted into n syntax trees through a recursive algorithm, and root nodes of the syntax trees are A0-An-1 in sequence; performing depth-first search on the generated n syntax trees, and automatically generating all signal names; and generating an IO signal integration record file according to a pre-formulated IO signal integration template. According to the method, the nested structural body is automatically converted into the syntax tree, so that the labor time is saved; according to the invention, depth-first search is carried out on the syntax tree to automatically generate all IO signals, which is simple and accurate.

Description

technical field [0001] The invention relates to an automatic integration technology of IO signals of a FADEC operating system, in particular to an automatic integration method of IO signals based on a FADEC operating system. Background technique [0002] Aero-engine control software (FADEC software) is usually coded in C language. At present, most FADEC software consists of operating system software (Operating Software, OS software) and application layer software (Application Software, AS software). OS software and AS software perform their respective duties, and share and interact with signals through the As_interface.h interface file, so as to ensure the normal and stable operation of the FADEC software. The As_interface.h interface file contains power-on self-check signals (CPU math operation and logic operation self-check, RAM self-check, FLASH self-check, watchdog self-check, CPU timer self-check), analog input signal, switch Input signal, analog output signal, switch...
