Intelligent artificial hand control system

Abstract

The invention discloses an intelligent artificial hand control system. The intelligent artificial hand control system comprises a driving motor, a signal acquisition module, a signal processing module, a power supply module, a master control module and a motor driving module. The signal acquisition module is used for acquiring electromyographic signals on the surface of an arm; the signal processing module is used for filtering and amplifying the electromyographic signals and then sends the electromyographic signals to the master control module; the master control module is used for carrying out motion classified calculation to the received electromyographic signals to obtain a control signal and sends the control signal to the motor driving module; the motor driving module is used for controlling the driving motor; and the power supply module supplies power to the driving motor and the master control module through secondary voltage conversion, and can provide different output voltages by changing parameter values of electronic components. Current isolation between the driving motor and the master control is achieved, influence of the driving motor on the master control module is avoided, at the same time, the intelligent artificial hand control system can control artificial hands of different models through different output voltages.

Description

technical field [0001] The invention relates to the field of rehabilitation medical equipment, in particular to an intelligent artificial hand control system. Background technique [0002] For a long time, thousands of patients with physical disabilities caused by various diseases, work-related injuries, natural disasters, traffic accidents, etc., have many inconveniences in work, study and life due to the disability of the limbs. Prosthetics are in high demand as one of the main methods for these physically disabled persons to partially restore their limb function. As upper limb disabilities account for a large proportion of physical disabilities, the demand for prosthetic hands is also increasing. Therefore, research and development of the control and monitoring of prosthetic hands is of great significance to help people with physical disabilities to take care of themselves and improve their quality of life. [0003] Most of the existing prosthetic hand control systems i...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing prosthetic hand control systems include signal acquisition, main control, drive and other modules, but a designed prosthetic hand control system can only control a specific prosthetic hand, and the model, power, and rated voltage of the prosthetic hand drive motor are fixed. To replace the control system, the prosthetic hand control system is not universal

Moreover, the feedback functions of most prosthetic hand control systems are not comprehensive, and the speed detection, over-current protection, over-current warning, communication and display modules are missing or partially missing

At the same time, the monitoring function during the operation of the prosthetic hand is relatively lacking. At present, the movement of the prosthetic hand is mostly observed visually. Even if some systems have display modules, they cannot effectively display the speed, position information and changes of the prosthetic hand in real time.
