Interaction control device and method oriented to intelligent indoor assisting system

Abstract

The invention discloses an interaction control device and an interaction control system oriented to an intelligent indoor assisting system, which are used for controlling postural transform of an intelligent wheel chair body among sitting, laying and standing, the motions of the intelligent wheel chair and automatic jointing between the wheel chair body and a bed body. The device comprises an embedded upper computer, a motion control unit, a postural transform control unit, a non-visual sensing unit, a visual sensing and processing unit and a human-computer interaction unit. Under the cooperative control of each unit, the intelligent wheel chair body can work in the three operating modes of wheel chair assistance, postural transform and bed body automatic-entry jointing, and simultaneously can visually display and monitor the working condition information of the wheel chair, the physiological parameter information of a human body and ambient environment information. The invention also discloses a visual servo-based method for the intelligent wheel chair to automatically enter the bed body for jointing by using the interaction control device.

Description

technical field [0001] The invention relates to the fields of intelligent control systems, embedded image processing and visual servoing, in particular to an interactive control system oriented to intelligent indoor motion assistance systems. Background technique [0002] In order to meet the needs of patients and the elderly in different positions such as lying down and standing, and reduce the labor intensity of nursing staff, it is of practical significance to design an intelligent mobility system with strong functions to meet daily needs and easy to operate and control. The existing problems of the current assisting system include: poor flexibility and operability when in a wheelchair state; when in a prone position, its width and height cannot meet the nursing requirements and lack comfort; The transition process between sitting, lying and standing positions of the moving system is complicated; the control method and human-computer interaction method are single; the req...
