Problems solved by technology

[0006] 1. The network transmission method is limited by the underlying network transmission protocol, and the network transmission speed is difficult to meet the real-time requirements of the centrifugal dynamic flight simulator for the centrifugal dynamic flight command transmission, so that the centrifugal dynamic flight command obtained by the manned centrifuge side The curve is in a large ladder shape, which introduces system disturbance, causing high-frequency vibration of the manned centrifuge, reducing the service life of the manned centrifuge, and causing discomfort to the pilot;
[0007] 2. The network transmission methods include isochronous network and non-isochronous network, which are limited to the transmission between two different operating systems of manned centrifuges and flight simulators. The network transmission method is usually non-isochronous network. For non-isochronous networks, the command transmission time interval will fluctuate within a certain range. If the centrifugal dynamic flight command is directly interpolated, it is difficult to achieve the optimal interpolation effect due to the uncertain command transmission time interval.

Embodiment Construction

[0077] The present invention will be further described below in conjunction with accompanying drawing:

[0078] Such as figure 1 As shown, the pilot operates the throttle, joystick and other flight equipment to generate real-time operation instructions, which are processed by the flight simulator to generate centrifugal dynamic flight real-time instructions, which are transmitted to the manned centrifuge through the network, and the manned centrifuge responds to the centrifugal force. Dynamic flight real-time command to realize centrifugal dynamic flight simulation process.

[0079] The manned centrifuge is composed of a motion control system and a three-degree-of-freedom centrifuge, and the real-time interpolation method described in the present invention is implemented in the motion control system. When the centrifugal dynamic flight real-time command is transmitted to the motion control system, the program in the motion control system is processed according to the real-tim...

Abstract

The invention discloses a real-time interpolation method for a centrifugal dynamic flight instruction fit for network transmission. The method comprises the following steps: receiving a centrifugal dynamic flight real-time instruction; storing a present instruction as a cache instruction; receiving the real-time instruction, generating and sending a trigger signal; receiving the trigger signal and statistically recording interpolation count; assessing and acquiring the maximum stable interpolation count; receiving the trigger signal and statistically recording an instruction updating period; assessing and acquiring the maximum stable interpolation instruction period; selecting an interpolation method complying with the equipment running rule; performing interpolation between the real-time instruction and the cache instruction, thereby acquiring an interpolation flight instruction; and correcting and adjusting the maximum stable interpolation count and the maximum stable interpolation instruction period. According to the real-time interpolation method provided by the invention, the function of automatically matching with different network transmission periods is achieved, the optimum stable interpolation centrifugal dynamic flight instruction can be acquired and the vibration problem of a centrifugal dynamic flight stimulator caused by disturbance of the dynamic flight instruction can be effectively solved.

Description

technical field [0001] The invention relates to a centrifugal dynamic flight command interpolation method, in particular to a centrifugal dynamic flight command real-time interpolation method suitable for network transmission. Background technique [0002] With the development of high-performance fighters, the abnormal speed, acceleration and angular motion stimulation produced by their high-speed and large maneuvering characteristics will seriously affect the physiological and psychological state of the pilots, and easily cause loss of consciousness (G-LOC), spatial orientation disorder (SD ), etc., threatening flight safety. The field of aviation medicine believes that carrying out manned centrifuge training is an indispensable and important measure to improve the pilot's physical adaptability in the air and ensure flight safety, and it is regarded as an indispensable, safe and economical training item for pilot training. [0003] Centrifugal dynamic flight simulator is a...
