Method and system used for processing instrument flight parameters of simple simulated flight trainer

Abstract

The invention discloses a method and a system used for processing instrument flight parameters of a simple simulated flight trainer. A trainer main machine is connected with an instrument by a low-speed interface; when the instrument is driven, the received data are subjected to a spline fitting algorithm and a sensitivity adjusting algorithm, a high-sample frequency data sequence is simulated by recent data nodes, the instrument is driven to work according to the characteristic of a step motor, an excellent smooth feeling is obtained, the delay is offset, and low-sample frequency data are prevented from directly driving the instrument to bring the jump feeling to eyes.

Description

technical field [0001] The invention relates to the field of aircraft training data processing, in particular to a method and system for processing instrument flight parameters in a simple simulated flight training device. Background technique [0002] In the development of the flight training device, it is necessary to transmit the main flight parameters produced by the simulation software to the instrument equipment in real time to reduce the influence of signal transmission delay, which is one of the key technologies to improve the fidelity of the flight training device. For simple-level trainers, the delay mainly comes from the frequency of data collection and the time consumption of data transmission on the bus. In order to overcome this delay, the traditional method is to increase the frequency of data collection as much as possible, and use dedicated High-speed transmission network system, which results in high cost and increases the difficulty of research and develop...

For simple-level trainers, the delay mainly comes from the frequency of data collection and the time consumption of data transmission on the bus. In order to overcome this delay, the traditional method is to increase the frequency of data collection as much as possible, and use dedicated High-speed transmission network system, which causes high cost and increases the difficulty of research and development

At present, RS485, USB or CAN buses are popularly used in low-cost simple trainers. Due to the limited data throughput of this low-cost bus system, it is necessary to ensure low data acquisition frequency and transmission rate to ensure access to more There are many node devices and stability, so the data transmission delay of the trainer based on this bus system is relatively obvious, which reduces the trainee's sense of reality and affects the training effect
