Embodiment Construction

[0049] The present invention is described in detail below in conjunction with accompanying drawing:

[0050] see figure 1, a mind-controlled intelligent prosthetic movement system, including an EEG acquisition module, an EEG analysis module, a drive control module, and a joint angle feedback module.

[0051] EEG acquisition module: collect the EEG signals of the cerebral cortex and amplify them and convert them into analog-to-digital conversion. The signals are transmitted from the Bluetooth module to the EEG analysis module;

[0052] EEG analysis module: perform feature extraction and pattern recognition on incoming EEG signals, and transfer the pattern recognition results to the drive control module;

[0053] Drive control module: According to the input pattern recognition result, the angular position information of the corresponding pattern in the memory is retrieved, and combined with the angle information fed back by the angle sensor to form a control instruction, so as ...

Abstract

The invention belongs to the control field and relates to an intelligent artificial limb movement system based on idiodynamics and control methods thereof. The problems of single recognition mode and low universality of an existing artificial limb system in the prior art are solved. The system comprises an electroencephalogram acquisition module, an electroencephalogram analysis module, a drive control module and a joint angle feedback module. The control methods include the control method in a training mode and the control method in a using mode. The training mode and the using mode are switched through a key. In the training mode, other electroencephalograms are selectively entered as required except a quiescent state, and the quiescent state is a necessary enter item to ensure accurate control of the system. When a user completes electroencephalogram entering in the training mode, a system state is switched to the using mode, and the user can send corresponding electroencephalograms to control the arms to execute corresponding actions.

Description

technical field [0001] The invention belongs to the field of control, and relates to an intelligent artificial limb movement system based on idea control and a control method thereof. Background technique [0002] In today's society, millions of people are forced to amputate due to diseases, industrial injuries, wars, traffic accidents and some accidental injuries. With the acceleration of modernization, this number is growing at an alarming rate. According to the survey, there are about 60 million physically disabled people in my country, and there is little hope in the near future to completely rely on foreign products to meet the needs of domestic disabled people. In the second half of the 20th century, prosthetic technology has achieved rapid development. The traditional prosthesis control method is mainly to implant electrodes into the contact part of the patient's body and the prosthesis, and use the myoelectric signals collected by the electrodes to control the move...
