Microgravity environment simulation operation training system and control method thereof

Abstract

The invention relates to a microgravity environment simulation operation training system and a control method thereof, the training system comprises an industrial personal computer, a router, a single-person training device and a VR head-mounted display, the single-person training device is composed of a main control board, a fixed platform, eight flexible cable driving units, eight flexible cables and an end effector; the flexible cable driving units are fixedly connected to eight end points of the fixed platform respectively to control the position of the platform, and the end effector corresponding to the acting position of a virtual task object receives interaction force applied by an astronaut to the end effector through the six-axis force sensor. An upper computer program of the industrial personal computer can render a virtual task scene picture in real time through a control method, transmit the virtual task scene picture to the VR head-mounted display and control the flexible cable driving unit to change the position of a fixed platform in the single-person training device to simulate a microgravity environment; the single-person training device can flexibly adjust an actual site, and the astronauts can see real-time training information in a virtual task scene through rapid image rendering, so that the feeling is more intuitive, and the training is more efficient.

Description

technical field [0001] The invention relates to the control technology of a cable-driven parallel robot, in particular to a training system and a control method for astronauts in a microgravity environment simulation operation. Background technique [0002] In the field of astronaut microgravity environment simulation operation training, many existing technologies have disclosed the training system invented by them, but there is still a lack of an efficient microgravity environment simulation operation training system for actual training. At this stage, MATLAB and dSPACE are mostly used for debugging and training systems. This method is very efficient in domains that do not require real-time rendering of images. But in the field of microgravity environment simulation operation training, this debugging method is complicated, because astronauts need to see the rendered virtual mission scene in real time, and debuggers also need to see some real-time data information from the ...
