Embodiment Construction

[0033] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0034] The invention aims at the problem of tremor in the existing arm movement process, and provides a system for assisting arm movement.

[0035] Such as figure 1 As shown, the system for assisting arm movement provided by the embodiment of the present invention includes: a detection module 11, a control module 12, an actuator 13, and a power supply module 14 for supplying power to the detection module 11, the control module 12, and the actuator 13; ,

[0036] The detection module 11 is configured to detect the motion feedback signal of the user's arm;

[0037] The control module 12 is configured to analyze the detected motion feedback signal of the user's arm, use the signal separation algorithm to filter the analysis result to obtain the tremor sig...

Abstract

The invention provides a system for assisting arm movement. The system can inhibit and relieve trembling behaviors of a user and comprises a detection module, a control module, an execution module anda power source module for powering the detection module, the control module and the execution module, the detection module is used for detecting a movement feedback signal of a user arm, and the control module is used for analyzing the movement feedback signal of the user arm acquired by detection, utilizing a signal separation algorithm to filter an analysis result to acquire a trembling signalof the arm and utilizing a feedforward control strategy and PID controller to control the execution mechanism according to the acquired trembling signal of the arm, wherein the PID controller refers to a proportion, integration and differentiation controller.

Description

technical field [0001] The invention relates to the field of sensing measurement and electronic control, in particular to a system for assisting arm movement. Background technique [0002] Parkinson's disease (Parkinson's Disease, PD) is a neurodegenerative disease that leads to the gradual loss of the brain's ability to control muscles, but so far, the real cause of Parkinson's disease has not been found. [0003] The well-known main obvious symptom of Parkinson's disease is resting tremor. In addition, patients will also have symptoms such as muscle and joint stiffness, stiffness of body parts, slow movement and poor balance. As the number of patients with Parkinson's disease is increasing year by year, the data shows that the growth rate of the number of Parkinson's patients in my country has entered a stage of rapid growth, which not only adds great pressure to the patients themselves, but also brings great pressure to the patients' families and society. come a heavy bur...
