Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with a system that has an acquisition calculation function, an actuation calculation function, and two control calculation functions:

[0031] Build steps:

[0032] 1. Analyze the input data and output data of control calculation function 1 and control calculation function 2, and on this basis, compile these two control calculation functions into control calculation component 1 (7) and control calculation component 2 (7) ( The dependent input data temporarily uses local local data); analyze the input data and output data of the acquisition calculation function and the action calculation function (in this example, it is assumed that the acquisition calculation function does not depend on other input data, and the action calculation function does not depend on other output data) , compiling the acquisition calculation function into an acquisition calculation component (7), and compiling the actuation f...

Abstract

The invention belongs to a fly-by-wire calculation technology, and relates to a fly-by-wire software data stream partition framework and a construction method of the framework. The method comprises the following steps: defining an input partition (1), a calculation partition (2), an output partition (3) and a system data dictionary (4); constructing a customer function corresponding to input data and a producer function corresponding to output data for each partition; establishing a mapping relation between the input data and the output data as well as a global data dictionary; defining a sequence calling assembly, an input output assembly and a calculation assembly according to a componentization principle. The framework provided by the invention can perform effective management on the full-system data stream in partition-based fly-by-wire system software, and reduces module coupling and verification costs.

Description

technical field [0001] The invention belongs to the fly-by-wire flight control computing technology, and relates to a software data flow framework of a fly-by-wire flight control system and a method for building the framework. Background technique [0002] In the computing platform of fly-by-wire flight control, data flow is the focus of system structural design and the basic element of interaction between various functional modules. The management of data flow directly affects the correctness of the system. In the prior art, since there is no partition in the software, the management of the data flow is dispersed in each functional module, resulting in large module coupling and difficulty in verification. The method provided by the invention can effectively manage the data flow of the whole system in the partition-based fly-by-wire flight control system software, and reduce module coupling and verification costs. Contents of the invention [0003] The object of the prese...
