Device and method for testing time delay of aircraft simulator system

Abstract

The invention relates to a device and a method for testing time delay of an aircraft simulator system, and belongs to the technical field of computer distributed simulation application. The invention discloses a device and a method for testing time delay of an aircraft simulator system. The device comprises a high-speed oscilloscope and a photosensitive sensor. The photosensitive sensor is used for converting an image brightness change signal of the visual system into a voltage change signal; the high-speed oscilloscope is used for receiving cabin control signals and photosensitive sensor signals, and the cabin control signals and the photosensitive sensor signals belong to different channels; wherein the cabin control signal is an electric signal converted from a control instruction of a cabin control device acquired by a digital quantity and / or analog quantity acquisition module. The method has the following advantages: 1, the transmission delay of the aircraft simulator system is detected by using the high-speed oscilloscope, so that relatively accurate delay time can be obtained; and 2, the test method is rapid and visual, and has relatively high reliability and relatively strong universality.

Description

technical field [0001] The invention relates to a device and method for testing the time delay of an aircraft simulator system, belonging to the technical field of computer distributed simulation applications. Background technique [0002] At present, with a large number of aircraft simulators equipped troops, more and more users pay more and more attention to the real-time performance of the simulator, and the time delay of the aircraft simulator system is one of the key indicators for evaluating the real-time performance of the simulator. According to the requirements of the national military standard GJB1395A-2009 "General Specifications for Aircraft Simulators", "Aircraft simulators should have the minimum system time delay. The time delay should be less than 140ms". [0003] The transmission delay of the aircraft simulator system is mainly reflected in the time consumed by the pilot's operation data from the cockpit simulation system to the visual system through the in...

Problems solved by technology

At present, there is no specific detection method in China. If you purchase foreign detection equipment and install it, the cost is high, which is not conducive to the scientific research and production of simulators in large quantities.

At present, there is no specific detection method for the transmission delay of the simulator system in most domestic, mainly relying on the pilot's intuitive feeling to identify, or the method of theoretical analysis
