Mechanical exoskeleton data acquisition control device

Abstract

The invention provides a mechanical exoskeleton data acquisition control device, which comprises a first traction rope and a shell sheath. A positioning block is arranged at one end of the shell sheath; a sleeve is arranged at the other end of the shell sheath; the shell sheath comprises a plurality of limiting blocks; an adjusting block corresponding to the positioning block is arranged at one end of the first traction rope, and a first displacement sensor is arranged at the other end of the first traction rope; a first limiting block is arranged on the first traction rope; and a first elastic piece is arranged between the first limiting block and the sleeve. During working, the limb drives the shell sheath and the first traction rope to bend to trigger the first displacement sensor to work, and the first displacement sensor generates a signal, processes the signal and transmits the signal to an external motor to drive the first traction rope to work. The mechanical exoskeleton data acquisition control device can accurately reflect human motion details, is high in data acquisition precision, has a displacement signal amplification function, and is sensitive in signal response, lowin error rate and good in user experience effect.

Description

technical field [0001] The invention relates to the field of sensor data acquisition, in particular to a mechanical exoskeleton data acquisition control device. Background technique [0002] With the frequent occurrence of people's physical health problems in modern society, the health problems of the elderly and some disabled people have received widespread attention from the whole society, among which limb disability is an important problem that affects people's lives. Exoskeleton control devices can provide external assistance for people with physical mobility difficulties and help them recover a certain degree of exercise ability, which is of great significance for improving physical mobility difficulties and reducing the burden on families and society. [0003] The exoskeleton data acquisition and control device is an acquisition and control device installed on the exoskeleton control device. It is composed of an acquisition system and a control system. There are two ma...

AI Technical Summary

Problems solved by technology

[0005] 1. Due to the need to place sensors at different positions of the human body, the cost of the acquisition device will be too high, and the installation of multiple sensors makes the overall structure more complicated, the error rate is high, and the corresponding motion information cannot be accurately collected. Poor use effect;

[0006] 2. Set the biomass sensor and use the electromyographic signal to control. Due to the immature biosensing system at present, the electromyographic signal cannot completely correspond to the joint torque, which makes the information acquisition rate of the entire acquisition device slow and the cost is high.
