Control system for active movement of astronaut and control method thereof

Abstract

The invention relates to the field of astronaut motion control, in particular to a control system for active motion of an astronaut and a control method thereof. The system comprises a current resistance module coaxial with a rotating shaft of the running machine and a control module used for controlling the current resistance module. The control module comprises a tablet computer, a digital signal processor connected with the tablet computer, a digital-to-analog converter connected with the digital signal processor, an operational amplifier connected with the digital-to-analog converter, a current mirror connected with the operational amplifier, and a Hall sensor. The system is installed on a space running machine, the current resistance module is adopted as a resistance source to be installed on the rotating shaft, resistance output of the rotating shaft of the running machine is controlled, rotation of a running belt of the running machine is blocked, and therefore the muscles of an astronaut actively exert force to overcome resistance, and the active movement effect is achieved. The exercise effect of the astronaut can be evaluated in real time through an algorithm, and the on-orbit active exercise function of the astronaut is achieved.

Description

technical field [0001] The invention relates to the field of motion control of astronauts, in particular to a control system for active motion of astronauts and a control method thereof. Background technique [0002] Under microgravity conditions, astronauts lose bone at a rate of 1% to 2% per month (especially in the lower extremities such as the proximal femur), accompanied by serious effects such as muscle atrophy, which seriously restricts astronauts' in-orbit and Work. With the development of manned spaceflight, the requirements for the physical health of astronauts in orbit are getting higher and higher, and the demand for astronauts' exercise products will also increase, which has attracted great attention and widespread attention in the United States, Germany, the United Kingdom and other countries. s concern. [0003] NASA's active space treadmill uses a DC motor to drive the running belt to achieve the purpose of exercise. The exerciser's muscles are passively ex...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the disadvantages of bone loss and muscle atrophy caused by the passive running of existing astronauts on orbit, the present invention provides a control system and control method for active movement of astronauts, so that astronauts need to actively exercise to exert force Overcome the resistance movement, and can evaluate the exercise effect of astronauts in real time, so as to achieve the purpose of active exercise for astronauts in orbit
