Abstract

The invention discloses an upper limb rehabilitation system based on biological signals. An EEG cap is attached to the surface of the brain, and the EEG signal is sensed through the EEG cap. After the EEG signal is amplified, filtered, and denoised, the CSP feature The extraction algorithm and the classifier with adaptive LDA classification algorithm perform feature extraction and classification, and convert them into driving instructions for controlling the driving motor equipment and pneumatic muscle auxiliary equipment, and the central processing unit of the system combines the driving instructions and the motion state collected by the motion state collector After the data is fused and sorted, the number is fed back to the drive motor equipment, pneumatic tendon auxiliary equipment and mobile terminal, so as to drive the mechanical arm to perform rehabilitation exercises; the staff can remotely monitor the patient's exercise and rehabilitation status through the mobile terminal, and the patient can also input it through voice , The output device invokes the rehabilitation game in the display platform to perform auxiliary rehabilitation training. This improves the effectiveness of patient training while ensuring safety and stability during training.

Description

technical field

[0001] The invention belongs to the technical field of computer intelligent control, and more specifically relates to an upper limb rehabilitation system based on biological signals. Background technique

[0002] In modern society, upper limb movement disorders caused by stroke, hemiplegia and other brain diseases have brought many difficulties to the lives of many middle-aged and elderly people. They need scientific rehabilitation training to help them restore limb motor function. In this context, the upper limb rehabilitation system based on biosignals has attracted people's attention as an effective device for upper limb rehabilitation training.

[0003] There are about 100 billion nerve cells in the human brain, of which there are 14 billion cells in the cerebral cortex, and each nerve cell has 10,000 neural connections at the same time, forming an extremely complex and huge network of nerve cells. Nerve cells are mainly composed of three parts: dendrite...
