Abstract

The invention discloses a general data processing framework and method based on a flight simulator, comprising: a data acquisition module, a data processing module, a configuration management module, a mode selection module and a network communication module. The data processing module is used to provide a data processing base class and has analog quantity, digital quantity, and combination switch data processing classes. The developer implements the processing of other types of signals by inheriting the data processing base class; the configuration management module uses It is used to realize the parameter configuration of data analysis and packaging according to different types through the graphical interface. The present invention can be used for analyzing, processing and packaging data of various types of acquisition cards of various types of flight simulators. The data processing framework of the present invention has a clear hierarchy, is efficient and stable, and has good scalability. The present invention can improve development efficiency and simplify Developers work.

Description

technical field [0001] The invention belongs to the technical field of flight simulators, and in particular relates to a general data processing framework for flight simulators. Background technique [0002] As the complexity of aircraft increases, flight simulators also become more complex, and more and more types of data need to be collected and processed in real time. As the basic guarantee for the normal operation of flight simulators, data collection and processing provide data sources for other aircraft simulation systems by providing real-time, accurate and stable collection and processing of cockpit equipment data. The data acquisition and processing system mainly completes the data interaction between the cockpit equipment hardware and other systems. On the one hand, it collects hardware analog signals, digital signals, ARINC429, RS-422 and other bus signals, processes the collected signals, and sends them to Flight simulation, avionics simulation, integrated contr...

Problems solved by technology

[0004] 1. Low reusability, consuming repetitive labor

In addition to the different number of devices, each custom program has great similarities in other parts, such as commonly used digital quantities, analog quantities, combined switch processing, etc., which will lead to a lot of unnecessary repeated development work

[0005] 2. Scalability and poor maintainability

In the later stage, it is often necessary to add equipment or change equipment wiring problems or add one or several bus signals; the analog quantity will have zero drift problems due to the deformation of the mechanism; the analog quantity needs to be linearly transformed according to the protocol, and the transformation target value will vary according to the engineering experiment requirements.
